JUDGMENT
K.G. Balakrishnan, C.J.I.
Leave granted in SLP (Crl.) Nos. 10 of 2006 and 6711 of 2007.
1. The legal questions in this batch of criminal appeals relate
to the involuntary administration of certain scientific
techniques, namely narcoanalysis, polygraph examination and
the Brain Electrical Activation Profile (BEAP) test for the
1
purpose of improving investigation efforts in criminal cases.
This issue has received considerable attention since it involves
tensions between the desirability of efficient investigation and
the preservation of individual liberties. Ordinarily the judicial
task is that of evaluating the rival contentions in order to
arrive at a sound conclusion. However, the present case is not
an ordinary dispute between private parties. It raises pertinent
questions about the meaning and scope of fundamental rights
which are available to all citizens. Therefore, we must examine
the implications of permitting the use of the impugned
techniques in a variety of settings.
2. Objections have been raised in respect of instances where
individuals who are the accused, suspects or witnesses in an
investigation have been subjected to these tests without their
consent. Such measures have been defended by citing the
importance of extracting information which could help the
investigating agencies to prevent criminal activities in the
future as well as in circumstances where it is difficult to
gather evidence through ordinary means. In some of the
2
impugned judgments, reliance has been placed on certain
provisions of the Code of Criminal Procedure, 1973 and the
Indian Evidence Act, 1872 to refer back to the responsibilities
placed on citizens to fully co-operate with investigation
agencies. It has also been urged that administering these
techniques does not cause any bodily harm and that the
extracted information will be used only for strengthening
investigation efforts and will not be admitted as evidence
during the trial stage. The assertion is that improvements in
fact-finding during the investigation stage will consequently
help to increase the rate of prosecution as well as the rate of
acquittal. Yet another line of reasoning is that these scientific
techniques are a softer alternative to the regrettable and
allegedly widespread use of `third degree methods' by
investigators.
3. The involuntary administration of the impugned techniques
prompts questions about the protective scope of the `right
against self-incrimination' which finds place in Article 20(3) of
our Constitution. In one of the impugned judgments, it has
3
been held that the information extracted through methods
such as `polygraph examination' and the `Brain Electrical
Activation Profile (BEAP) test' cannot be equated with
`testimonial compulsion' because the test subject is not
required to give verbal answers, thereby falling outside the
protective scope of Article 20(3). It was further ruled that the
verbal revelations made during a narcoanalysis test do not
attract the bar of Article 20(3) since the inculpatory or
exculpatory nature of these revelations is not known at the
time of conducting the test. To address these questions among
others, it is necessary to inquire into the historical origins and
rationale behind the `right against self-incrimination'. The
principal questions are whether this right extends to the
investigation stage and whether the test results are of a
`testimonial' character, thereby attracting the protection of
Article 20(3). Furthermore, we must examine whether relying
on the test results or materials discovered with the help of the
same creates a reasonable likelihood of incrimination for the
test subject.
4
4. We must also deal with arguments invoking the guarantee
of `substantive due process' which is part and parcel of the
idea of `personal liberty' protected by Article 21 of the
Constitution. The first question in this regard is whether the
provisions in the Code of Criminal Procedure, 1973 that
provide for `medical examination' during the course of
investigation can be read expansively to include the impugned
techniques, even though the latter are not explicitly
enumerated. To answer this question, it will be necessary to
discuss the principles governing the interpretation of statutes
in light of scientific advancements. Questions have also been
raised with respect to the professional ethics of medical
personnel involved in the administration of these techniques.
Furthermore, Article 21 has been judicially expanded to
include a `right against cruel, inhuman or degrading
treatment', which requires us to determine whether the
involuntary administration of the impugned techniques
violates this right whose scope corresponds with evolving
international human rights norms. We must also consider
5
contentions that have invoked the test subject's `right to
privacy', both in a physical and mental sense.
5. The scientific validity of the impugned techniques has been
questioned and it is argued that their results are not entirely
reliable. For instance, the narcoanalysis technique involves the
intravenous administration of sodium pentothal, a drug which
lowers inhibitions on part of the subject and induces the
person to talk freely. However, empirical studies suggest that
the drug-induced revelations need not necessarily be true.
Polygraph examination and the BEAP test are methods which
serve the respective purposes of lie-detection and gauging the
subject's familiarity with information related to the crime.
These techniques are essentially confirmatory in nature,
wherein inferences are drawn from the physiological responses
of the subject. However, the reliability of these methods has
been repeatedly questioned in empirical studies. In the context
of criminal cases, the reliability of scientific evidence bears a
causal link with several dimensions of the right to a fair trial
such as the requisite standard of proving guilt beyond
6
reasonable doubt and the right of the accused to present a
defence. We must be mindful of the fact that these
requirements have long been recognised as components of
`personal liberty' under Article 21 of the Constitution. Hence it
will be instructive to gather some insights about the
admissibility of scientific evidence.
6. In the course of the proceedings before this Court, oral
submissions were made by Mr. Rajesh Mahale, Adv. (Crl. App.
No. 1267 of 2004), Mr. Manoj Goel, Adv. (Crl. App. Nos. 56-57
of 2005), Mr. Santosh Paul, Adv. (Crl. App. No. 54 of 2005)
and Mr. Harish Salve, Sr. Adv. (Crl. App. Nos. 1199 of 2006
and No. 1471 of 2007) - all of whom argued against the
involuntary administration of the impugned techniques.
Arguments defending the compulsory administration of these
techniques were presented by Mr. Goolam E. Vahanvati,
Solicitor General of India [now Attorney General for India] and
Mr. Anoop G. Choudhari, Sr. Adv. who appeared on behalf of
the Union of India. These were further supported by Mr. T.R.
Andhyarujina, Sr. Adv. who appeared on behalf of the Central
7
Bureau of Investigation (CBI) and Mr. Sanjay Hegde, Adv. who
represented the State of Karnataka. Mr. Dushyant Dave, Sr.
Adv., rendered assistance as amicus curiae in this matter.
7. At this stage, it will be useful to frame the questions of law
and outline the relevant sub-questions in the following
manner:
I. Whether the involuntary administration of the impugned
techniques violates the `right against self-incrimination'
enumerated in Article 20(3) of the Constitution?
I-A. Whether the investigative use of the impugned
techniques creates a likelihood of incrimination for the
subject?
I-B. Whether the results derived from the impugned
techniques amount to `testimonial compulsion' thereby
attracting the bar of Article 20(3)?
8
II. Whether the involuntary administration of the impugned
techniques is a reasonable restriction on `personal liberty' as
understood in the context of Article 21 of the Constitution?
8. Before answering these questions, it is necessary to
examine the evolution and specific uses of the impugned
techniques. Hence, a description of each of the test procedures
is followed by an overview of their possible uses, both within
and outside the criminal justice system. It is also necessary to
gauge the limitations of these techniques. Owing to the dearth
of Indian decisions on this subject, we must look to precedents
from foreign jurisdictions which deal with the application of
these techniques in the area of criminal justice.
DESCRIPTIONS OF TESTS - USES, LIMITATIONS AND
PRECEDENTS
Polygraph Examination
9. The origins of polygraph examination have been traced back
to the efforts of Lombroso, a criminologist who experimented
9
with a machine that measured blood pressure and pulse to
assess the honesty of persons suspected of criminal conduct.
His device was called a hydrosphygmograph. A similar device
was used by psychologist William Marston during World War I
in espionage cases, which proved to be a precursor to its use
in the criminal justice system. In 1921, John Larson
incorporated the measurement of respiration rate and by 1939
Leonard Keeler added skin conductance and an amplifier to
the parameters examined by a polygraph machine.
10. The theory behind polygraph tests is that when a subject
is lying in response to a question, he/she will produce
physiological responses that are different from those that arise
in the normal course. During the polygraph examination,
several instruments are attached to the subject for measuring
and recording the physiological responses. The examiner then
reads these results, analyzes them and proceeds to gauge the
credibility of the subject's answers. Instruments such as
cardiographs, pneumographs, cardio-cuffs and sensitive
electrodes are used in the course of polygraph examinations.
10
They measure changes in aspects such as respiration, blood
pressure, blood flow, pulse and galvanic skin resistance. The
truthfulness or falsity on part of the subject is assessed by
relying on the records of the physiological responses. [See:
Laboratory Procedure Manual - Polygraph Examination
(Directorate of Forensic Science, Ministry of Home Affairs,
Government of India, New Delhi - 2005)]
11. There are three prominent polygraph examination
techniques:
i. The relevant-irrelevant (R-I) technique
ii. The control question (CQ) technique
iii. Directed Lie-Control (DLC) technique
Each of these techniques includes a pre-test interview during
which the subject is acquainted with the test procedure and
the examiner gathers the information which is needed to
finalize the questions that are to be asked. An important
objective of this exercise is to mitigate the possibility of a
feeling of surprise on part of the subject which could be
triggered by unexpected questions. This is significant because
11
an expression of surprise could be mistaken for physiological
responses that are similar to those associated with deception.
[Refer: David Gallai, `Polygraph evidence in federal courts:
Should it be admissible?' 36 American Criminal Law Review
87-116 (Winter 1999) at p. 91]. Needless to say, the polygraph
examiner should be familiar with the details of the ongoing
investigation. To meet this end the investigators are required
to share copies of documents such as the First Information
Report (FIR), Medico-Legal Reports (MLR) and Post-Mortem
Reports (PMR) depending on the nature of the facts being
investigated.
12. The control-question (CQ) technique is the most commonly
used one and its procedure as well as scoring system has been
described in the materials submitted on behalf of CBI. The test
consists of control questions and relevant questions. The
control questions are irrelevant to the facts being investigated
but they are intended to provoke distinct physiological
responses, as well as false denials. These responses are
compared with the responses triggered by the relevant
12
questions. Theoretically, a truthful subject will show greater
physiological responses to the control questions which he/she
has reluctantly answered falsely, than to the relevant
questions, which the subject can easily answer truthfully.
Conversely, a deceptive subject will show greater physiological
responses while giving false answers to relevant questions in
comparison to the responses triggered by false answers to
control questions. In other words, a guilty subject is more
likely to be concerned with lying about the relevant facts as
opposed to lying about other facts in general. An innocent
subject will have no trouble in truthfully answering the
relevant questions but will have trouble in giving false answers
to control questions. The scoring of the tests is done by
assigning a numerical value, positive or negative, to each
response given by the subject. After accounting for all the
numbers, the result is compared to a standard numerical
value to indicate the overall level of deception. The net
conclusion may indicate truth, deception or uncertainty.
13
13. The use of polygraph examinations in the criminal justice
system has been contentious. In this case, we are mainly
considered with situations when investigators seek reliance on
these tests to detect deception or to verify the truth of previous
testimonies. Furthermore, litigation related to polygraph tests
has also involved situations where suspects and defendants in
criminal cases have sought reliance on them to demonstrate
their innocence. It is also conceivable that witnesses can be
compelled to undergo polygraph tests in order to test the
credibility of their testimonies or to question their mental
capacity or to even attack their character.
14. Another controversial use of polygraph tests has been on
victims of sexual offences for testing the veracity of their
allegations. While several states in the U.S.A. have enacted
provisions to prohibit such use, the text of the Laboratory
Procedure Manual for Polygraph Examination [supra.] indicates
that this is an acceptable use. In this regard, Para 3.4 (v) of
the said Manual reads as follows:
14
"(v) In cases of alleged sex offences such as intercourse
with a female child, forcible rape, indecent liberties or
perversion, it is important that the victim, as well as the
accused, be made available for interview and polygraph
examination. It is essential that the polygraph examiner
get a first hand detailed statement from the victim, and
the interview of the victim precede that of the suspect or
witnesses. ..."
[The following article includes a table which lists out the
statutorily permissible uses of polygraph examination in the
different state jurisdictions of the United States of America:
Henry T. Greely and Judy Illes, `Neuroscience based lie-
detection: The urgent need for regulation', 33 American
Journal of Law and Medicine, 377-421 (2007)]
15. The propriety of compelling the victims of sexual offences
to undergo a polygraph examination certainly merits
consideration in the present case. It must also be noted that in
some jurisdictions polygraph tests have been permitted for the
purpose of screening public employees, both at the stage of
recruitment and at regular intervals during the service-period.
In the U.S.A., the widespread acceptance of polygraph tests for
checking the antecedents and monitoring the conduct of
15
public employees has encouraged private employers to resort
to the same. In fact the Employee Polygraph Protection Act,
1998 was designed to restrict their use for employee screening.
This development must be noted because the unqualified
acceptance of `Lie-detector tests' in India's criminal justice
system could have the unintended consequence of
encouraging their use by private parties.
16. Polygraph tests have several limitations and therefore a
margin for errors. The premise behind these tests is
questionable because the measured changes in physiological
responses are not necessarily triggered by lying or deception.
Instead, they could be triggered by nervousness, anxiety, fear,
confusion or other emotions. Furthermore, the physical
conditions in the polygraph examination room can also create
distortions in the recorded responses. The test is best
administered in comfortable surroundings where there are no
potential distractions for the subject and complete privacy is
maintained. The mental state of the subject is also vital since
a person in a state of depression or hyperactivity is likely to
16
offer highly disparate physiological responses which could
mislead the examiner. In some cases the subject may have
suffered from loss of memory in the intervening time-period
between the relevant act and the conduct of the test. When the
subject does not remember the facts in question, there will be
no self-awareness of truth or deception and hence the
recording of the physiological responses will not be helpful.
Errors may also result from `memory-hardening', i.e. a process
by which the subject has created and consolidated false
memories about a particular incident. This commonly occurs
in respect of recollections of traumatic events and the subject
may not be aware of the fact that he/she is lying.
17. The errors associated with polygraph tests are broadly
grouped into two categories, i.e., `false positives' and `false
negatives'. A `false positive' occurs when the results indicate
that a person has been deceitful even though he/she answered
truthfully. Conversely a `false negative' occurs when a set of
deceptive responses is reported as truthful. On account of
such inherent complexities, the qualifications and competence
17
of the polygraph examiner are of the utmost importance. The
examiner needs to be thorough in preparing the questionnaire
and must also have the expertise to account for extraneous
conditions that could lead to erroneous inferences.
18. However, the biggest concern about polygraph tests is that
an examiner may not be able to recognise deliberate attempts
on part of the subject to manipulate the test results. Such
`countermeasures' are techniques which are deliberately used
by the subject to create certain physiological responses in
order to deceive the examiner. The intention is that by
deliberately enhancing one's reaction to the control questions,
the examiner will incorrectly score the test in favour of
truthfulness rather than deception. The most commonly used
`countermeasures' are those of creating a false sense of mental
anxiety and stress at the time of the interview, so that the
responses triggered by lying cannot be readily distinguished.
19. Since polygraph tests have come to be widely relied upon
for employee screening in the U.S.A., the U.S. Department of
18
Energy had requested the National Research Council of the
National Academies (NRC) to review their use for different
purposes. The following conclusion was stated in its report,
i.e. The Polygraph and Lie-Detection: Committee to Review the
scientific evidence on the Polygraph (Washington D.C.: National
Academies Press, 2003) at pp. 212-213:
"Polygraph Accuracy: Almost a century of research in
scientific psychology and physiology provides little basis
for the expectation that a polygraph test could have
extremely high accuracy. The physiological responses
measured by the polygraph are not uniquely related to
deception. That is, the responses measured by the
polygraph do not all reflect a single underlying process: a
variety of psychological and physiological processes,
including some that can be consciously controlled, can
affect polygraph measures and test results. Moreover,
most polygraph testing procedures allow for uncontrolled
variation in test administration (e.g., creation of the
emotional climate, selecting questions) that can be
expected to result in variations in accuracy and that limit
the level of accuracy that can be consistently achieved.
Theoretical Basis: The theoretical rationale for the
polygraph is quite weak, especially in terms of differential
fear, arousal, or other emotional states that are triggered
in response to relevant or comparison questions. We have
not found any serious effort at construct validation of
polygraph testing.
Research Progress: Research on the polygraph has not
progressed over time in the manner of a typical scientific
field. It has not accumulated knowledge or strengthened
its scientific underpinnings in any significant manner.
19
Polygraph research has proceeded in relative isolation
from related fields of basic science and has benefited
little from conceptual, theoretical, and technological
advances in those fields that are relevant to the
psychophysiological detection of deception.
Future Potential: The inherent ambiguity of the
physiological measures used in the polygraph suggests
that further investments in improving polygraph
technique and interpretation will bring only modest
improvements in accuracy."
20. A Working Party of the British Psychological Society (BPS)
also came to a similar conclusion in a study published in
2004. The key finding is reproduced below, [Cited from: A
Review of the current scientific status and fields of application
of polygraph deception detection - Final Report (6 October,
2004) from The British Psychological Society (BPS) Working
Party at p. 10]:
"A polygraph is sometimes called a lie detector, but this
term is misleading. A polygraph does not detect lies, but
only arousal which is assumed to accompany telling a lie.
Polygraph examiners have no other option than to
measure deception in such an indirect way, as a pattern
of physiological activity directly related to lying does not
exist (Saxe, 1991). Three of the four most popular lie
detection procedures using the polygraph
(Relevant/Irrelevant Test, Control Question Test and
Directed Lie Test, ...) are built upon the premise that,
while answering so-called `relevant' questions, liars will
20
be more aroused than while answering so-called `control'
questions, due to a fear of detection (fear of getting
caught lying). This premise is somewhat naive as truth
tellers may also be more aroused when answering the
relevant questions, particularly: (i) when these relevant
questions are emotion evoking questions (e.g. when an
innocent man, suspected of murdering his beloved wife,
is asked questions about his wife in a polygraph test, the
memory of his late wife might re-awaken his strong
feelings about her); and (ii) when the innocent examinee
experiences fear, which may occur, for example, when
the person is afraid that his or her honest answers will
not be believed by the polygraph examiner. The other
popular test (Guilty Knowledge Test, ...) is built upon the
premise that guilty examinees will be more aroused
concerning certain information due to different orienting
reactions, that is, they will show enhanced orienting
responses when recognising crucial details of a crime.
This premise has strong support in psychophysiological
research (Fiedler, Schmidt & Stahl, 2002)."
21. Coming to judicial precedents, a decision reported as Frye
v. United States, (1923) 54 App DC 46, dealt with a precursor
to the polygraph which detected deception by measuring
changes in systolic blood pressure. In that case the defendant
was subjected to this test before the trial and his counsel had
requested the court that the scientist who had conducted the
same should be allowed to give expert testimony about the
results. Both the trial court and the appellate court rejected
the request for admitting such testimony. The appellate court
21
identified the considerations that would govern the
admissibility of expert testimony based on scientific insights. It
was held, Id. at p. 47:
"... Just when a scientific principle or discovery crosses
the line between the experimental and demonstrable
stages is difficult to define. Somewhere in this twilight
zone the evidential force of the principle must be
recognized, and while courts will go a long way in
admitting expert testimony deduced from a well-
recognized scientific principle or discovery, the thing from
which the deduction is made must be sufficiently
established to have gained general acceptance in the
particular field in which it belongs.
We think the systolic blood pressure deception test has
not yet gained such standing and scientific recognition
among physiological and psychological authorities as
would justify the courts in admitting expert testimony
deduced from the discovery, development, and
experiments thus far made."
22. The standard of `general acceptance in the particular field'
governed the admissibility of scientific evidence for several
decades. It was changed much later by the U.S. Supreme
Court in Daubert v. Merrell Dow Pharmaceuticals Inc., 509
US 579 (1993). In that case the petitioners had instituted
proceedings against a pharmaceutical company which had
marketed `Bendectin', a prescription drug. They had alleged
22
that the ingestion of this drug by expecting mothers had
caused birth defects in the children born to them. To contest
these allegations, the pharmaceutical company had submitted
an affidavit authored by an epidemiologist. The petitioners had
also submitted expert opinion testimony in support of their
contentions. The District Court had ruled in favour of the
company by ruling that their scientific evidence met the
standard of `general acceptance in the particular field' whereas
the expert opinion testimony produced on behalf of the
petitioners did not meet the said standard. The Court of
Appeals for the Ninth Circuit upheld the judgment and the
case reached the U.S. Supreme Court which vacated the
appellate court's judgment and remanded the case back to the
trial court. It was unanimously held that the `general
acceptance' standard articulated in Frye (supra.) had since
been displaced by the enactment of the Federal Rules of
Evidence in 1975, wherein Rule 702 governed the admissibility
of expert opinion testimony that was based on scientific
findings. This rule provided that:
23
If scientific, technical, or other specialized knowledge will
assist the trier of fact to understand the evidence or to
determine a fact in issue, a witness qualified as an expert
by knowledge, skill, experience, training, or education,
may testify thereto in the form of an opinion or otherwise.
23. It was held that the trial court should have evaluated the
scientific evidence as per Rule 702 of the Federal Rules of
Evidence which mandates an inquiry into the relevance as well
as the reliability of the scientific technique in question. The
majority opinion (Blackmun, J.) noted that the trial judge's
first step should be a preliminary assessment of whether the
testimony's underlying reasoning or methodology is
scientifically valid and whether it can be properly applied to
the facts in issue. Several other considerations will be
applicable, such as:
7 whether the theory or technique in question can be and
has been tested
7 whether it has been subjected to peer review and
publication
7 its known or potential error rate
24
7 the existence and maintenance of standards controlling
its operation
7 whether it has attracted widespread acceptance within
the scientific community
24. It was further observed that such an inquiry should be a
flexible one, and its focus must be solely on principles and
methodology, not on the conclusions that they generate. It was
reasoned that instead of the wholesale exclusion of scientific
evidence on account of the high threshold of proving `general
acceptance in the particular field', the same could be admitted
and then challenged through conventional methods such as
cross-examination, presentation of contrary evidence and
careful instructions to juries about the burden of proof. In this
regard, the trial judge is expected to perform a `gate-keeping'
role to decide on the admission of expert testimony based on
scientific techniques. It should also be kept in mind that Rule
403 of the Federal Rules of Evidence, 1975 empowers a trial
judge to exclude any form of evidence if it is found that its
probative value will be outweighed by its prejudicial effect.
25
25. Prior to the Daubert decision (supra.), most jurisdictions
in the U.S.A. had disapproved of the use of polygraph tests in
criminal cases. Some State jurisdictions had absolutely
prohibited the admission of polygraph test results, while a few
had allowed consideration of the same if certain conditions
were met. These conditions included a prior stipulation
between the parties to undergo these tests with procedural
safeguards such as the involvement of experienced examiners,
presence of counsel and proper recording to enable
subsequent scrutiny. A dissonance had also emerged in the
treatment of polygraph test results in the different Circuit
jurisdictions, with some jurisdictions giving trial judges the
discretion to enquire into the reliability of polygraph test
results on a case-by-case basis.
26. For example, in United States v. Piccinonna, 885 F.2d
1529 (11th Circ. 1989), it was noted that in some instances
polygraphy satisfied the standard of `general acceptance in the
particular field' as required by Frye (supra.). It was held that
26
polygraph testimony could be admissible under two situations,
namely when the parties themselves agree on a stipulation to
this effect or for the purpose of impeaching and corroborating
the testimony of witnesses. It was clarified that polygraph
examination results could not be directly used to bolster the
testimony of a witness. However, they could be used to attack
the credibility of a witness or even to rehabilitate one after
his/her credibility has been attacked by the other side.
Despite these observations, the trial court did not admit the
polygraph results on remand in this particular case.
27. However, after Daubert (supra.) prescribed a more liberal
criterion for determining the admissibility of scientific
evidence, some Courts ruled that weightage could be given to
polygraph results. For instance in United States v. Posado,
57 F.3d 428 (5th Circ. 1995), the facts related to a pre-trial
evidentiary hearing where the defendants had asked for the
exclusion of forty-four kilograms of cocaine that had been
recovered from their luggage at an airport. The District Court
had refused to consider polygraph evidence given by the
27
defendants in support of their version of events leading up to
the seizure of the drugs and their arrest. On appeal, the Fifth
Circuit Court held that the rationale for disregarding
polygraph evidence did not survive the Daubert decision. The
Court proceeded to remand the case to the trial court and
directed that the admissibility of the polygraph results should
be assessed as per the factors enumerated in Daubert
(supra.). It was held, Id. at p. 434:
"There can be no doubt that tremendous advances have
been made in polygraph instrumentation and technique
in the years since Frye. The test at issue in Frye
measured only changes in the subject's systolic blood
pressure in response to test questions. [Frye v. United
States ...] Modern instrumentation detects changes in the
subject's blood pressure, pulse, thoracic and abdominal
respiration, and galvanic skin response. Current research
indicates that, when given under controlled conditions,
the polygraph technique accurately predicts truth or
deception between seventy and ninety percent of the
time. Remaining controversy about test accuracy is
almost unanimously attributed to variations in the
integrity of the testing environment and the qualifications
of the examiner. Such variation also exists in many of the
disciplines and for much of the scientific evidence we
routinely find admissible under Rule 702. [See
McCormick on Evidence 206 at 915 & n. 57] Further,
there is good indication that polygraph technique and the
requirements for professional polygraphists are becoming
progressively more standardized. In addition, polygraph
technique has been and continues to be subjected to
extensive study and publication. Finally, polygraph is
28
now so widely used by employers and government
agencies alike.
To iterate, we do not now hold that polygraph
examinations are scientifically valid or that they will
always assist the trier of fact, in this or any other
individual case. We merely remove the obstacle of the per
se rule against admissibility, which was based on
antiquated concepts about the technical ability of the
polygraph and legal precepts that have been expressly
overruled by the Supreme Court."
(internal citations omitted)
28. Despite these favourable observations, the polygraph
results were excluded by the District Court on remand.
However, we have come across at least one case decided after
Daubert (supra.) where a trial court had admitted expert
opinion testimony about polygraph results. In United States
v. Galbreth, 908 F. Supp 877 (D.N.M. 1995), the District
Court took note of New Mexico Rule of Evidence 11-707 which
established standards for the admission of polygraph evidence.
The said provision laid down that polygraph evidence would be
admissible only when the following conditions are met: the
examiner must have had at least 5 years experience in
conducting polygraph tests and 20 hours of continuing
education within the past year; the polygraph examination
29
must be tape recorded in its entirety; the polygraph charts
must be scored quantitatively in a manner generally accepted
as reliable by polygraph experts; all polygraph materials must
be provided to the opposing party at least 10 days before trial;
and all polygraph examinations conducted on the subject
must be disclosed. It was found that all of these requirements
had been complied with in the facts at hand. The District
Court concluded with these words, Id. at p. 896:
"... the Court finds that the expert opinion testimony
regarding the polygraph results of defendant Galbreth is
admissible. However, because the evidentiary reliability of
opinion testimony regarding the results of a particular
polygraph test is dependent upon a properly conducted
examination by a highly qualified, experienced and skilful
examiner, nothing in this opinion is intended to reflect
the judgment that polygraph results are per se
admissible. Rather, in the context of the polygraph
technique, trial courts must engage upon a case specific
inquiry to determine the admissibility of such testimony."
29. We were also alerted to the decision in United States v.
Cordoba, 104 F.3d 225 (9th. Circ. 1997). In that case, the
Ninth Circuit Court concluded that the position favouring
absolute exclusion of unstipulated polygraph evidence had
effectively been overruled in Daubert (supra.). The defendant
30
had been convicted for the possession and distribution of
cocaine since the drugs had been recovered from a van which
he had been driving. However, when he took an unstipulated
polygraph test, the results suggested that he was not aware of
the presence of drugs in the van. At the trial stage, the
prosecution had moved to suppress the test results and the
District Court had accordingly excluded the polygraph
evidence. However, the Ninth Circuit Court remanded the case
back after finding that the trial judge should have adopted the
parameters enumerated in Daubert (supra.) to decide on the
admissibility of the polygraph test results. It was observed, Id.
at p. 228:
"With this holding, we are not expressing new
enthusiasm for admission of unstipulated polygraph
evidence. The inherent problematic nature of such
evidence remains. As we noted in Brown, polygraph
evidence has grave potential for interfering with the
deliberative process. [Brown v. Darcy, 783 F.2d 1389 (9th
Circ. 1986) at 1396-1397] However, these matters are for
determination by the trial judge who must not only
evaluate the evidence under Rule 702, but consider
admission under Rule 403. Thus, we adopt the view of
Judge Jameson's dissent in Brown that these are matters
which must be left to the sound discretion of the trial
court, consistent with Daubert standards."
31
30. The decisions cited above had led to some uncertainty
about the admissibility of polygraph test results. However, this
uncertainty was laid to rest by an authoritative ruling of the
U.S. Supreme Court in United States v. Scheffer, 523 US
303 (1998). In that case, an eight judge majority decided that
Military Rule of Evidence 707 (which made polygraph results
inadmissible in court-martial proceedings) did not violate an
accused person's Sixth Amendment right to present a defence.
The relevant part of the provision follows:
"(a) Notwithstanding any other provision of law, the
results of a polygraph examination, the opinion of a
polygraph examiner, or any reference to an offer to take,
failure to take, or taking of a polygraph examination,
shall not be admitted into evidence."
31. The facts were that Scheffer, a U.S. Air Force serviceman
had faced court-martial proceedings because a routine
urinalysis showed that he had consumed methamphetamines.
However, a polygraph test suggested that he had been truthful
in denying the intentional consumption of the drugs. His
defence of `innocent ingestion' was not accepted during the
court-martial proceedings and the polygraph results were not
32
admitted in evidence. The Air Force Court of Criminal Appeals
affirmed the decision given in the court-martial proceedings
but the Court of Appeals for the Armed Forces reversed the
same by holding that an absolute exclusion of polygraph
evidence (offered to rebut an attack on the credibility of the
accused) would violate Scheffer's Sixth Amendment right to
present a defence. Hence, the matter reached the Supreme
Court which decided that the exclusion of polygraph evidence
did not violate the said constitutional right.
32. Eight judges agreed that testimony about polygraph test
results should not be admissible on account of the inherent
unreliability of the results obtained. Four judges agreed that
reliance on polygraph results would displace the fact-finding
role of the jury and lead to collateral litigation. In the words of
Clarence Thomas, J., Id. at p. 309:
"Rule 707 serves several legitimate interests in the
criminal trial process. These interests include ensuring
that only reliable evidence is introduced at trial,
preserving the jury's role in determining credibility, and
avoiding litigation that is collateral to the primary
purpose of the trial. The rule is neither arbitrary nor
disproportionate in promoting these ends. Nor does it
33
implicate a sufficiently weighty interest of the defendant
to raise a constitutional concern under our precedents."
33. On the issue of reliability, the Court took note of some
Circuit Court decisions which had permitted trial courts to
consider polygraph results in accordance with the Daubert
factors. However, the following stance was adopted, Id. at p.
312:
"... Although the degree of reliability of polygraph
evidence may depend upon a variety of identifiable
factors, there is simply no way to know in a particular
case whether a polygraph examiner's conclusion is
accurate, because certain doubts and uncertainties
plague even the best polygraph exams. Individual
jurisdictions therefore may reasonably reach differing
conclusions as to whether polygraph evidence should be
admitted. We cannot say, then, that presented with such
widespread uncertainty, the President acted arbitrarily or
disproportionately in promulgating a per se rule
excluding all polygraph evidence."
34. Since a trial by jury is an essential feature of the criminal
justice system in the U.S.A., concerns were expressed about
preserving the jury's core function of determining the
credibility of testimony. It was observed, Id. at p. 314:
" ... Unlike other expert witnesses who testify about
factual matters outside the jurors' knowledge, such as
the analysis of fingerprints, ballistics, or DNA found at a
crime scene, a polygraph expert can supply the jury only
34
with another opinion, in addition to its own, about
whether the witness was telling the truth. Jurisdictions,
in promulgating rules of evidence, may legitimately be
concerned about the risk that juries will give excessive
weight to the opinions of a polygrapher, clothed as they
are in scientific expertise and at times offering, as in
respondent's case, a conclusion about the ultimate issue
in the trial. Such jurisdictions may legitimately determine
that the aura of infallibility attending polygraph evidence
can lead jurors to abandon their duty to assess
credibility and guilt. ..."
35. On the issue of encouraging litigation that is collateral to
the primary purpose of a trial, it was held, Id. at p. 314:
"... Allowing proffers of polygraph evidence would
inevitably entail assessments of such issues as whether
the test and control questions were appropriate, whether
a particular polygraph examiner was qualified and had
properly interpreted the physiological responses, and
whether other factors such as countermeasures
employed by the examinee had distorted the exam
results. Such assessments would be required in each and
every case. It thus offends no constitutional principle for
the President to conclude that a per se rule excluding all
polygraph evidence is appropriate. Because litigation over
the admissibility of polygraph evidence is by its very
nature collateral, a per se rule prohibiting its admission
is not an arbitrary or disproportionate means of avoiding
it."
36. In the same case, Kennedy, J. filed an opinion which was
joined by four judges. While there was agreement on the
questionable reliability of polygraph results, a different stand
35
was taken on the issues pertaining to the role of the jury and
the concerns about collateral litigation. It was observed that
the inherent reliability of the test results is a sufficient ground
to exclude the polygraph test results and expert testimony
related to them. Stevens, J. filed a dissenting opinion in this
case.
37. We have also come across a decision of the Canadian
Supreme Court in R v Beland, [1987] 36 C.C.C. (3d) 481. In
that case the respondents had been charged with conspiracy
to commit robbery. During their trial, one of their accomplices
had given testimony which directly implicated them. The
respondents contested this testimony and after the completion
of the evidentiary phase of the trial, they moved an application
to re-open their defence while seeking permission for each of
them to undergo a polygraph examination and produce the
results in evidence. The trial judge denied this motion and the
respondents were convicted. However, the appellate court
allowed their appeal from conviction and granted an order to
re-open the trial and directed that the polygraph results be
36
considered. On further appeal, the Supreme Court of Canada
held that the results of a polygraph examination are not
admissible as evidence. The majority opinion explained that
the admission of polygraph test results would offend some well
established rules of evidence. It examined the `rule against
oath-helping' which prohibits a party from presenting evidence
solely for the purpose of bolstering the credibility of a witness.
Consideration was also given to the `rule against admission of
past or out-of-court statements by a witness' as well as the
restrictions on producing `character evidence'. The discussion
also concluded that polygraph evidence is inadmissible as
`expert evidence'.
38. With regard to the `rule against admission of past or out-
of-court statements by a witness', McIntyre, J. observed (in
Para. 11):
"... In my view, the rule against admission of consistent
out-of-court statements is soundly based and
particularly apposite to questions raised in connection
with the use of the polygraph. Polygraph evidence when
tendered would be entirely self-serving and would shed
no light on the real issues before the court. Assuming, as
in the case at bar, that the evidence sought to be
37
adduced would not fall within any of the well recognized
exceptions to the operation of the rule - where it is
permitted to rebut the allegation of a recent fabrication or
to show physical, mental or emotional condition - it
should be rejected. To do otherwise is to open the trial
process to the time-consuming and confusing
consideration of collateral issues and to deflect the focus
of the proceedings from their fundamental issue of guilt
or innocence. This view is summarized by D.W. Elliott in
`Lie-Detector Evidence: Lessons from the American
Experience' in Well and Truly Tried (Law Book Co., 1982),
at pp. 129-30:
A defendant who attempts to put in the results of a
test showing this truthfulness on the matters in
issue is bound to fall foul of the rule against self-
serving statements or, as it is sometimes called, the
rule that a party cannot manufacture evidence for
himself, and the falling foul will not be in any mere
technical sense. The rule is sometimes applied in a
mechanical unintelligent way to exclude evidence
about which no realistic objection could be raised,
as the leading case, Gillie v. Posho shows; but
striking down defence polygraph evidence on this
ground would be no mere technical reflex action of
legal obscurantists. The policy behind the doctrine
is a fundamental one, and defence polygraph
evidence usually offends it fundamentally. As some
judges have pointed out, only those defendants who
successfully take examinations are likely to want
the results admitted. There is no compulsion to put
in the first test results obtained. A defendant can
take the test many times, if necessary "examiner-
shopping", until he gets a result which suits him.
Even stipulated tests are not free of this taint,
because of course his lawyers will advise him to
have several secret trial runs before the prosecution
is approached. If nothing else, the dry runs will
habituate him to the process and to the expected
relevant questions."
38
39. On the possibility of using polygraph test results as
character evidence, it was observed (Para. 14):
"... What is the consequence of this rule in relation to
polygraph evidence? Where such evidence is sought to be
introduced it is the operator who would be called as the
witness and it is clear, of course, that the purpose of his
evidence would be to bolster the credibility of the accused
and, in effect, to show him to be of good character by
inviting the inference that he did not lie during the test.
In other words, it is evidence not of general reputation
but of a specific incident and its admission would be
precluded under the rule. It would follow, then, that the
introduction of evidence of the polygraph tests would
violate the character evidence rule."
40. Mcintyre, J. offered the following conclusions (at Paras. 18,
19 and 20):
"18. In conclusion, it is my opinion, based upon a
consideration of rules of evidence long established and
applied in our courts, that the polygraph has no place in
the judicial process where it is employed as a tool to
determine or to test the credibility of witnesses. It is
frequently argued that the polygraph represents an
application of modern scientific knowledge and
experience to the task of determining the veracity of
human utterances. It is said that the courts should
welcome this device and not cling to the imperfect
methods of the past in such an important task. This
argument has a superficial appeal, but, in my view, it
cannot prevail in the face of realities of court procedures.
19. I would say at once that this view is not based on a
fear of the inaccuracies of the polygraph. On that
39
question we were not supplied with sufficient evidence to
reach a conclusion. However, it may be said that even the
finding of a significant percentage of errors in its results
would not, by itself, be sufficient ground to exclude it as
an instrument for use in the courts. Error is inherent in
human affairs, scientific or unscientific. It exists within
our established court procedures and must always be
guarded against. The compelling reason, in my view, for
the exclusion of the evidence of polygraph results in
judicial proceedings is two-fold. First, the admission of
polygraph evidence would run counter to the well
established rules of evidence which have been referred to.
Second, while there is no reason why the rules of
evidence should not be modified where improvement will
result, it is my view that the admission of polygraph
evidence will serve no purpose which is not already
served. It will disrupt proceedings, cause delays, and lead
to numerous complications which will result in no
greater degree of certainty in the process than that which
already exists.
20. Since litigation replaced trial by combat, the
determination of fact, including the veracity of parties
and their witnesses, has been the duty of judges or juries
upon an evaluation of the statements of witnesses. This
approach has led to the development of a body of rules
relating to the giving and reception of evidence and we
have developed methods which have served well and have
gained a wide measure of approval. They have facilitated
the orderly conduct of judicial proceedings and are
designed to keep the focus of the proceedings on the
principal issue, in a criminal case, the guilt or innocence
of the accused. What would be served by the introduction
of evidence of polygraph readings into the judicial
process? To begin with, it must be remembered that
however scientific it may be, its use in court depends on
the human intervention of the operator. Whatever results
are recorded by the polygraph instrument, their nature
and significance reach the trier of fact through the mouth
40
of the operator. Human fallibility is therefore present as
before, but now it may be said to be fortified with the
mystique of science. ..."
Narcoanalysis technique
41. This test involves the intravenous administration of a drug
that causes the subject to enter into a hypnotic trance and
become less inhibited. The drug-induced hypnotic stage is
useful for investigators since it makes the subject more likely
to divulge information. The drug used for this test is sodium
pentothal, higher quantities of which are routinely used for
inducing general anaesthesia in surgical procedures. This
drug is also used in the field of psychiatry since the
revelations can enable the diagnosis of mental disorders.
However, we have to decide on the permissibility of resorting to
this technique during a criminal investigation, despite its'
established uses in the medical field. The use of `truth-serums'
and hypnosis is not a recent development. Earlier versions of
the narcoanalysis technique utilised substances such as
scopolamine and sodium amytal. The following extracts from
an article trace the evolution of this technique, [Cited from:
41
C.W. Muehlberger, `Interrogation under Drug-influence: The
so-called Truth serum technique', 42(4) The Journal of
Criminal Law, Criminology and Police Science 513-528 (Nov-
Dec. 1951) at pp. 513-514]:
"With the advent of anaesthesia about a century ago, it
was observed that during the induction period and
particularly during the recovery interval, patients were
prone to make extremely naove remarks about personal
matters, which, in their normal state, would never have
revealed.
Probably the earliest direct attempt to utilize this
phenomenon in criminal interrogation stemmed from
observations of a mild type of anaesthesia commonly
used in obstetrical practice during the period of about
1903-1915 and known as `Twilight sleep'. This
anaesthesia was obtained by hypodermic injection of
solutions of morphine and scopolamine (also called
`hyoscine') followed by intermittent chloroform
inhalations if needed. The pain relieving qualities of
morphine are well known. Scopolamine appears to have
the added property of blocking out memories of recent
events. By the combination of these drugs in suitable
dosage, morphine dulled labor pains without materially
interfering with the muscular contractions of labor, while
scopolamine wiped out subsequent memories of the
delivery room ordeal. The technique was widely used in
Europe but soon fell into disrepute among obstetricians
of this country, largely due to overdosage.
During the period of extensive use of `twilight sleep' it
was a common experience that women who were under
drug influence, were extremely candid and uninhibited in
their statements. They often made remarks which
obviously would never have been uttered when in their
42
normal state. Dr. Robert E. House, an observant
physician practising in Ferris, Texas, believed that a drug
combination which was so effective in the removal of
ordinary restraints and which produced such utter
candor, might be of value in obtaining factual
information from persons who were thought to be lying.
Dr. House's first paper presented in 1922 suggested drug
administration quite similar to the standard `twilight
sleep' procedure: an initial dose of < grain of morphine
sulphate together with 1/100 grain of scopolamine
hydrobromide, followed at 20-30 minute intervals with
smaller (1/200 - 1/400 grain) doses of scopolamine and
periods of light chloroform anaesthesia. Subjects were
questioned as they recovered from the light chloroform
anaesthesia and gave answers which subsequently
proved to be true. Altogether, Dr. House reported about
half-a-dozen cases, several of which were instrumental in
securing the release of convicts from State prisons, he
also observed that, after returning to their normal state,
these subjects had little or no recollection of what had
transpired during the period of interrogation. They could
not remember what questions had been asked, nor by
whom; neither could they recall any answers which they
had made."
42. The use of the `Scopolamine' technique led to the coining
of the expression `truth serum'. With the passage of time,
injections of sodium amytal came to be used for inducing
subjects to talk freely, primarily in the field of psychiatry. The
author cited above has further observed, Id. at p. 522:
"During World War II, this general technique of delving
into a subject's inner consciousness through the
instrumentality of narcotic drugs was widely used in the
43
treatment of war neuroses (sometimes called `Battle
shock' or `shell shock'). Fighting men who had been
through terrifically disturbing experiences often times
developed symptoms of amnesia, mental withdrawal,
negativity, paralyses, or many other mental, nervous, and
physical derangements. In most instances, these patients
refused to talk about the experiences which gave rise to
the difficulty, and psychiatrists were at a loss to discover
the crux of the problem. To intelligently counteract such
a force, it was first necessary to identify it. Thus, the use
of sedative drugs, first to analyze the source of
disturbance (narcoanalysis) and later to obtain the
proper frame of mind in which the patient could and
would `talk out' his difficulties, and, as they say `get them
off his chest' - and thus relieve himself (narco-synthesis
or narco-therapy) - was employed with signal success.
In the narcoanalysis of war neuroses a very light narcosis
is most desirable. With small doses of injectable
barbiturates (sodium amytal or sodium pentothal) or with
light inhalations of nitrous oxide or somnoform, the
subject pours out his pent-up emotions without much
prodding by the interrogator."
43. It has been shown that the Central Investigation Agency
(C.I.A.) in the U.S.A. had conducted research on the use of
sodium pentothal for aiding interrogations in intelligence and
counter-terrorism operations, as early as the 1950's [See
`Project MKULTRA - The CIA's program of research in
behavioral modification', On file with Schaffer Library of Drug
Policy, Text available from <www.druglibrary.org>]. In recent
44
years, the debate over the use of `truth-serums' has been
revived with demands for their use on persons suspected of
involvement in terrorist activities. Coming to the test
procedure, when the drug (sodium pentothal) is administered
intravenously, the subject ordinarily descends into
anaesthesia in four stages, namely:
(i) Awake stage
(ii) Hypnotic stage
(iii) Sedative stage
(iv) Anaesthetic stage
44. A relatively lighter dose of sodium pentothal is injected to
induce the `hypnotic stage' and the questioning is conducted
during the same. The hypnotic stage is maintained for the
required period by controlling the rate of administration of the
drug. As per the materials submitted before us, the behaviour
exhibited by the subject during this stage has certain specific
characteristics, namely:-
7 It facilitates handling of negative emotional
responses (i.e. guilt, avoidance, aggression,
45
frustration, non-responsiveness etc.) in a positive
manner.
7 It helps in rapid exploration and identification of
underlying conflicts in the subject's mind and
unresolved feelings about past events.
7 It induces the subject to divulge information which
would usually not be revealed in conscious
awareness and it is difficult for the person to lie at
this stage
7 The reversal from this stage occurs immediately
when the administration of the drug is
discontinued.
[Refer: Laboratory Procedure Manual - Forensic Narco-Analysis
(Directorate of Forensic Science, Ministry of Home Affairs,
Government of India, New Delhi - 2005); Also see John M.
Macdonald, `Truth Serum', 46(2) The Journal of Criminal Law,
Criminology and Police Science 259-263 (Jul.-Aug. 1955)]
45. The personnel involved in conducting a `narcoanalysis'
interview include a forensic psychologist, an anaesthesiologist,
46
a psychiatrist, a general physician or other medical staff and a
language interpreter if needed. Additionally a videographer is
required to create video-recordings of the test for subsequent
scrutiny. In India, this technique has been administered either
inside forensic science laboratories or in the operation theatres
of recognised hospitals. While a psychiatrist and general
physician perform the preliminary function of gauging whether
the subject is mentally and physically fit to undergo the test,
the anaesthesiologist supervises the intravenous
administration of the drug. It is the forensic psychologist who
actually conducts the questioning. Since the tests are meant
to aid investigation efforts, the forensic psychologist needs to
closely co-operate with the investigators in order to frame
appropriate questions.
46. This technique can serve several ends. The revelations
could help investigators to uncover vital evidence or to
corroborate pre-existing testimonies and prosecution theories.
Narcoanalysis tests have also been used to detect `malingering'
(faking of amnesia). The premise is that during the `hypnotic
47
stage' the subject is unable to wilfully suppress the memories
associated with the relevant facts. Thus, it has been urged
that drug-induced revelations can help to narrow down
investigation efforts, thereby saving public resources. There is
of course a very real possibility that information extracted
through such interviews can lead to the uncovering of
independent evidence which may be relevant. Hence, we must
consider the implications of such derivative use of the drug-
induced revelations, even if such revelations are not
admissible as evidence. We must also account for the uses of
this technique by persons other than investigators and
prosecutors. Narcoanalysis tests could be requested by
defendants who want to prove their innocence. Demands for
this test could also be made for purposes such as gauging the
credibility of testimony, to refresh the memory of witnesses or
to ascertain the mental capacity of persons to stand trial.
Such uses can have a direct impact on the efficiency of
investigations as well as the fairness of criminal trials. [See
generally: George H. Dession, Lawrence Z. Freedman, Richard
C. Donnelly and Frederick G. Redlich, `Drug-Induced
48
revelation and criminal investigation', 62 Yale Law Journal
315-347 (February 1953)]
47. It is also important to be aware of the limitations of the
`narcoanalysis' technique. It does not have an absolute
success rate and there is always the possibility that the
subject will not reveal any relevant information. Some studies
have shown that most of the drug-induced revelations are not
related to the relevant facts and they are more likely to be in
the nature of inconsequential information about the subjects'
personal lives. It takes great skill on part of the interrogators
to extract and identify information which could eventually
prove to be useful. While some persons are able to retain their
ability to deceive even in the hypnotic state, others can
become extremely suggestible to questioning. This is especially
worrying, since investigators who are under pressure to deliver
results could frame questions in a manner that prompts
incriminatory responses. Subjects could also concoct fanciful
stories in the course of the `hypnotic stage'. Since the
responses of different individuals are bound to vary, there is
49
no uniform criteria for evaluating the efficacy of the
`narcoanalysis' technique.
48. In an article published in 1951, C.W. Muehlberger (supra.)
had described a French case which attracted controversy in
1948. Raymond Cens, who had been accused of being a Nazi
collaborator, appeared to have suffered an apoplectic stroke
which also caused memory loss. The French Court trying the
case had authorised a board of psychiatrists to conduct an
examination for ascertaining the defendant's amnesia. The
narcoanalysis technique was used in the course of the
examination and the defendant did not object to the same.
However, the test results showed that the subject's memory
was not impaired and that he had been faking amnesia. At the
trial, testimony about these findings was admitted, thereby
leading to a conviction. Subsequently, Raymond Cens filed a
civil suit against the psychiatrists alleging assault and illegal
search. However, it was decided that the board had used
routine psychiatric procedures and since the actual physical
damage to the defendant was nominal, the psychiatrists were
50
acquitted. At the time, this case created quite a stir and the
Council of the Paris Bar Association had passed a resolution
against the use of drugs during interrogation. [Refer C.W.
Muehlberger (1951) at p. 527; The Raymond Cens case has
also been discussed in the following article: J.P. Gagnieur,
`The Judicial use of Psychonarcosis in France', 40(3) Journal of
Criminal Law and Criminology 370-380 (Sept.-Oct. 1949)]
49. An article published in 1961 [Andre A. Moenssens,
`Narcoanalysis in Law Enforcement', 52(4) The Journal of
Criminal Law, Criminology and Police Science 453-458 (Nov.-
Dec. 1961)] had surveyed some judicial precedents from the
U.S.A. which dealt with the forensic uses of the narcoanalysis
technique. The first reference is to a decision from the State of
Missouri reported as State v. Hudson, 314 Mo. 599 (1926). In
that case, the defence lawyer in a prosecution for rape
attempted to rely on the expert testimony of a doctor. The
doctor in turn declared that he had questioned the defendant
after injecting a truth-serum and the defendant had denied his
guilt while in a drug-induced state. The trial court had refused
51
to admit the doctor's testimony by finding it to be completely
unreliable from a scientific viewpoint. The appellate court
upheld the finding and made the following observation, Id. at
p. 602:
"Testimony of this character - barring the sufficient fact
that it cannot be classified otherwise than a self-serving
declaration - is, in the present state of human
knowledge, unworthy of serious consideration. We are
not told from what well this serum is drawn or in what
alembic its alleged truth compelling powers are distilled.
Its origin is as nebulous as its effect is uncertain. ..."
50. In State v. Lindemuth, 56 N.M. 237 (1952) the testimony
of a psychiatrist was not admitted when he wanted to show
that the answers given by a defendant while under the
influence of sodium pentothal supported the defendant's plea
of innocence in a murder case. The trial court's refusal to
admit such testimony was endorsed by the appellate court,
and it was noted, Id. at p. 243:
"Until the use of the drug as a means of procuring the
truth from people under its influence is accorded general
scientific recognition, we are unwilling to enlarge the
already immense field where medical experts, apparently
equally qualified, express such diametrically opposed
views on the same facts and conditions, to the despair of
the court reporter and the bewilderment of the fact-
finder."
52
51. However, Andre Moenssens (1961) also took note of a case
which appeared to endorse an opposing view. In People v.
Jones, 42 Cal. 2d 219 (1954), the trial court overruled the
prosecution's objection to the introduction of a psychiatrist's
testimony on behalf of the defendant. The psychiatrist had
conducted several tests on the defendant which included a
sodium pentothal induced interview. The Court found that this
was not sufficient to exclude the psychiatrist's testimony in its
entirety. It was observed that even though the truth of
statements revealed under narcoanalysis remains uncertain,
the results of the same could be clearly distinguished from the
psychiatrist's overall conclusions which were based on the
results of all the tests considered together.
52. At the federal level, the U.S. Court of Appeals for the Ninth
Circuit dealt with a similar issue in Lindsey v. United States,
237 F. 2d 893 (9th Circ. 1956). In that case, the trial court had
admitted a psychiatrist's opinion testimony which was based
on a clinical examination that included psychological tests and
53
a sodium pentothal induced interview. The subject of the
interview was a fifteen-year old girl who had been sexually
assaulted and had subsequently testified in a prosecution for
rape. On cross-examination, the credibility of the victim's
testimony had been doubted and in an attempt to rebut the
same, the prosecution had called on the psychiatrist. On the
basis of the results of the clinical examination, the psychiatrist
offered his professional opinion that the victim had been
telling the truth when she had repeated the charges that were
previously made to the police. This testimony was admitted as
a prior consistent statement to rehabilitate the witness but not
considered as substantive evidence. Furthermore, a tape
recording of the psychiatrist's interview with the girl, while she
was under narcosis, was also considered as evidence. The jury
went on to record a finding of guilt. When the case was
brought in appeal before the Ninth Circuit Court, the
conviction was reversed on the ground that the defendant had
been denied the `due process of law'. It was held that before a
prior consistent statement made under the influence of a
sodium pentothal injection could be admitted as evidence, it
54
should be scientifically established that the test is absolutely
accurate and reliable in all cases. Although the value of the
test in psychiatric examinations was recognised, it was
pointed out that the reliability of sodium pentothal tests had
not been sufficiently established to warrant admission of its
results in evidence. It was stated that "Scientific tests reveal
that people thus prompted to speak freely do not always tell
the truth". [Cited from Andre A. Moenssens (1961) at pp. 455-
456]
53. In Lawrence M. Dugan v. Commonwealth of Kentucky,
333 S.W.2d. 755 (1960), the defendant had been given a truth
serum test by a psychiatrist employed by him. The trial court
refused to admit the psychiatrist's testimony which supported
the truthfulness of the defendant's statement. The defendant
had pleaded innocence by saying that a shooting which had
resulted in the death of another person had been an accident.
The trial court's decision was affirmed on appeal and is was
reasoned that no court of last resort has recognised the
admissibility of the results of truth serum tests, the principal
55
ground being that such tests have not attained sufficient
recognition of dependability and reliability.
54. The U.S. Supreme Court has also disapproved of the
forensic uses of truth-inducing drugs in Townsend v. Sain,
372 US 293 (1963). In that case a heroin addict was arrested
on the suspicion of having committed robbery and murder.
While in custody he began to show severe withdrawal
symptoms, following which the police officials obtained the
services of a physician. In order to treat these withdrawal
symptoms, the physician injected a combined dosage of 1/8
grain of Phenobarbital and 1/230 grain of Hyoscine. Hyoscine
is the same as `Scopolamine' which has been described earlier.
This dosage appeared to have a calming effect on Townsend
and after the physician's departure he promptly responded to
questioning by the police and eventually made some
confessional statements. The petitioner's statements were duly
recorded by a court reporter. The next day he was taken to the
office of the prosecutor where he signed the transcriptions of
the statements made by him on the previous day. [The facts of
56
this case have also been discussed in: Charles E. Sheedy,
`Narcointerrogation of a Criminal Suspect', 50(2) The Journal
of Criminal Law, Criminology and Police Science 118-123 (July-
Aug 1959) at pp. 118-119]
55. When the case came up for trial, the counsel for the
petitioner brought a motion to exclude the transcripts of the
statements from the evidence. However, the trial judge denied
this motion and admitted the court reporter's transcription of
the confessional statements into evidence. Subsequently, a
jury found Townsend to be guilty, thereby leading to his
conviction. When the petitioner made a habeas corpus
application before a Federal District Court, one of the main
arguments advanced was that the fact of Scopolamine's
character as a truth-serum had not been brought out at the
time of the motion to suppress the statements or even at the
trial before the State Court. The Federal District Court denied
the habeas corpus petition without a plenary evidentiary
hearing, and this decision was affirmed by the Court of
Appeals. Hence, the matter came before the U.S. Supreme
57
Court. In an opinion authored by Earl Warren, C.J. the
Supreme Court held that the Federal District Court had erred
in denying a writ of habeas corpus without giving a plenary
evidentiary hearing to examine the voluntariness of the
confessional statements. Both the majority opinion as well as
the dissenting opinion (Stewart, J.) concurred on the finding
that a confession induced by the administration of drugs is
constitutionally inadmissible in a criminal trial. On this issue,
Warren, C.J. observed, 372 US 293 (1963), at pp. 307-308:
"Numerous decisions of this Court have established the
standards governing the admissibility of confessions into
evidence. If an individual's `will was overborne' or if his
confession was not `the product of a rational intellect and
a free will', his confession is inadmissible because
coerced. These standards are applicable whether a
confession is the product of physical intimidation or
psychological pressure and, of course, are equally
applicable to a drug-induced statement. It is difficult to
imagine a situation in which a confession would be less
the product of a free intellect, less voluntary, than when
brought about by a drug having the effect of a `truth
serum'. It is not significant that the drug may have been
administered and the questions asked by persons
unfamiliar with hyoscine's properties as a `truth serum',
if these properties exist. Any questioning by police
officers which in fact produces a confession which is not
the product of a free intellect renders that confession
inadmissible."

56. In United States v. Swanson, 572 F.2d 523 (5th Circ.
1978), two individuals had been convicted for conspiracy and
extortion through the acts of sending threatening letters. At
the trial stage, one of the defendants testified that he suffered
from amnesia and therefore he could not recall his alleged acts
of telephoning the co-defendant and mailing threatening
letters. In order to prove such amnesia his counsel sought the
admission of a taped interview between the defendant and a
psychiatrist which had been conducted while the defendant
was under the influence of sodium amytal. The drug-induced
statements supposedly showed that the scheme was a joke or
a prank. The trial court refused to admit the contents of this
sodium amytal induced interview and the Fifth Circuit Court
upheld this decision. In holding the same, it was also
observed, Id. at p. 528:
"... Moreover, no drug-induced recall of past events which
the subject is otherwise unable to recall is any more
reliable than the procedure for inducing recall. Here both
psychiatrists testified that sodium amytal does not
ensure truthful statements. No re-creation or recall, by
photograph, demonstration, drug-stimulated recall, or
otherwise, would be admissible with so tenuous a
predicate."
59
57. A decision given by the Ninth Circuit Court in United
States v. Solomon, 753 F. 2d 1522 (9th Circ. 1985), has been
cited by the respondents to support the forensic uses of the
narcoanalysis technique. However, a perusal of that judgment
shows that neither the actual statements made during
narcoanalysis interviews nor the expert testimony relating to
the same were given any weightage. The facts were that three
individuals, namely Solomon, Wesley and George (a minor at
the time of the crime) were accused of having committed
robbery and murder by arson. After their arrest, they had
changed their statements about the events relating to the
alleged offences. Subsequently, Wesley gave his consent for a
sodium amytal induced interview and the same was
administered by a psychiatrist named Dr. Montgomery. The
same psychiatrist also conducted a sodium amytal interview
with George, at the request of the investigators.
58. At the trial stage, George gave testimony which proved to
be incriminatory for Solomon and Wesley. However, the
statements made by Wesley during the narcoanalysis interview
60
were not admitted as evidence and even the expert testimony
about the same was excluded. On appeal, the Ninth Circuit
Court held that there had been no abuse of discretion by the
trial court in considering the evidence before it. Solomon and
Wesley had contended that the trial court should have
excluded the testimony given by George before the trial judge,
since the same was based on the results of the sodium amytal
interview and was hence unreliable. The Court drew a
distinction between the statements made during the
narcoanalysis interview and the subsequent statements made
before the trial court. It was observed that it was open to the
defendants to show that George's testimony during trial had
been bolstered by the previous revelations made during the
narcoanalysis interview. However, the connection between the
drug-induced revelations and the testimony given before the
trial court could not be presumed. It was further noted, Id. at
p. 1525:
"The only Ninth Circuit case addressing narcoanalysis
excluded a recording of and psychiatric testimony
supporting an interview conducted under the influence of
sodium pentothal, a precursor of sodium amytal.
[Lindsey v. United States, 237 F.2d 893 (9th Cir. 1956) ...]
61
The case at bar is distinguishable because no testimony
concerning the narcoanalysis was offered at trial. Only
George's current recollection of events was presented.
In an analogous situation, this circuit has held that the
current recollections of witnesses whose memories have
been refreshed by hypnosis are admissible, with the fact
of hypnosis relevant to credibility only [United States v.
Adams, 581 F.2d 193, 198-199 (9th Cir. 1978) ...], cert.
denied. We have cautioned, however, that "great care
must be exercised to insure" that statements after
hypnosis are not the product of hypnotic suggestion. Id.
We find no abuse of discretion in the trial court's ruling
to admit the testimony of the witness George. The court's
order denying Solomon's Motion to Suppress reflects a
careful balancing of reliability against prejudicial
dangers:"
59. However, Wesley wanted to introduce expert testimony by
Dr. Montgomery which would explain the effects of sodium
amytal as well as the statements made during his own drug-
induced interview. The intent was to rehabilitate Wesley's
credibility after the prosecution had impeached it with an
earlier confession. The trial court had held that even though
narcoanalysis was not reliable enough to admit into evidence,
Dr. Montgomery could testify about the statements made to
him by Wesley, however without an explanation of the
circumstances. On this issue, the Ninth Circuit Court referred
62
to the Frye standard for the admissibility of scientific
evidence. It was also noted that the trial court had the
discretion to draw the necessary balance between the
probative value of the evidence and its prejudicial effect. It
again took note of the decision in Lindsey v. United States,
237 F. 2d 893 (1956), where the admission of a tape recording
of a narcoanalysis interview along with an expert's explanation
of the technique was held to be a prejudicial error. The
following conclusion was stated, 753 F.2d 1522, at p. 1526:
"Dr. Montgomery testified also that narcoanalysis is
useful as a source of information that can be valuable if
verified through other sources. At one point he testified
that it would elicit an accurate statement of subjective
memory, but later said that the subject could fabricate
memories. He refused to agree that the subject would be
more likely to tell the truth under narcoanalysis than if
not so treated.
Wesley wanted to use the psychiatric testimony to bolster
the credibility of his trial testimony that George started
the fatal fire. Wesley's statement shortly after the fire was
that he himself set the fire. The probative value of the
statement while under narcoanalysis that George was
responsible, was the drug's tendency to induce truthful
statements.
Montgomery admitted that narcoanalysis does not
reliably induce truthful statements. The judge's exclusion
of the evidence concerning narcoanalysis was not an
abuse of discretion. The prejudicial effect of an aura of
63
scientific respectability outweighed the slight probative
value of the evidence."
60. In State of New Jersey v. Daryll Pitts, 56 A.2d 1320
(N.J. 1989), the trial court had refused to admit a part of a
psychiatrist's testimony which was based on the results of the
defendant's sodium-amytal induced interview. The defendant
had been charged with murder and had sought reliance on the
testimony to show his unstable state of mind at the time of the
homicides. Reliance on the psychiatrist's testimony was
requested during the sentencing phase of the trial in order to
show a mitigating factor. On appeal, the Supreme Court of
New Jersey upheld the trial court's decision to exclude that
part of the testimony which was derived from the results of the
sodium-amytal interview. Reference was made to the Frye
standard while observing that "in determining the
admissibility of evidence derived from scientific procedures, a
court must first ascertain the extent to which the reliability of
such procedures has attained general acceptance within the
relevant scientific community." (Id. at p. 1344) Furthermore,
the expert witnesses who had appeared at the trial had given
64
conflicting accounts about the utility of a sodium-amytal
induced interview for ascertaining the mental state of a
subject with regard to past events. It was stated, Id. at p.
1348:
"On the two occasions that this Court has considered the
questions, we have concluded, based on the then-existing
state of scientific knowledge, that testimony derived from
a sodium-amytal induced interview is inadmissible to
prove the truth of the facts asserted. [See State v. Levitt,
36 N.J. 266, 275 (1961)...; State v. Sinnott, ...132 A.2d
298 (1957)] Our rule is consistent with the views
expressed by other courts that have addressed the issue.
... The expert testimony adduced at the Rule 8 hearing
indicated that the scientific community continues to view
testimony induced by sodium amytal as unreliable to
ascertain truth. Thus, the trial court's ruling excluding
Dr. Sadoff's testimony in the guilt phase was consistent
with our precedents, with the weight of authority
throughout the country, and also with contemporary
scientific knowledge as reflected by the expert testimony.
..."
(internal citations omitted)
61. Since a person subjected to the narcoanalysis technique is
in a half-conscious state and loses awareness of time and
place, this condition can be compared to that of a person who
is in a hypnotic state. In Horvath v. R, [1979] 44 C.C.C. (2d)
385, the Supreme Court of Canada held that statements made
65
in a hypnotic state were not voluntary and hence they cannot
be admitted as evidence. It was also decided that if the post-
hypnotic statements relate back to the contents of what was
said during the hypnotic state, the subsequent statements
would be inadmissible. In that case a 17 year old boy
suspected for the murder of his mother had been questioned
by a police officer who had training in the use of hypnotic
methods. During the deliberate interruptions in the
interrogation sessions, the boy had fallen into a mild hypnotic
state and had eventually confessed to the commission of the
murder. He later repeated the admissions before the
investigating officers and signed a confessional statement. The
trial judge had found all of these statements to be
inadmissible, thereby leading to an acquittal. The Court of
Appeal had reversed this decision, and hence an appeal was
made before the Supreme Court.
62. Notably, the appellant had refused to undergo a
narcoanalysis interview or a polygraph test. It was also evident
that he had not consented to the hypnosis. The multiple
66
opinions delivered in the case examined the criterion for
deciding the voluntariness of a statement. Reference was made
to the well-known statement of Lord Summer in Ibrahim v. R,
[1914] A.C. 599 (P.C.), at p. 609:
"It has long been established as a positive rule of English
criminal law that no statement made by an accused is
admissible in evidence against him unless it is shown by
the prosecution to have been a voluntary statement, in
the sense that it has not been obtained from him either
by fear of prejudice or hope of advantage exercised or
held out by a person in authority."
63. In Horvath v. R (supra.), the question was whether
statements made under a hypnotic state could be equated
with those obtained by `fear of prejudice' or `hope of
advantage'. The Court ruled that the inquiry into the
voluntariness of a statement should not be literally confined to
these expressions. After examining several precedents, Spence
J. held that the total circumstances surrounding the
interrogation should be considered, with no particular
emphasis placed on the hypnosis. It was observed that in this
particular case the interrogation of the accused had resulted
in his complete emotional disintegration, and hence the
67
statements given were inadmissible. It was also held that the
rule in Ibrahim v. R (supra.) that a statement must be
induced by `fear of prejudice' or `hope of advantage' in order to
be considered involuntary was not a comprehensive test. The
word `voluntary' should be given its ordinary and natural
meaning so that the circumstances which existed in the
present case could also be described as those which resulted
in involuntary statements.
64. In a concurring opinion, Beetz., J. drew a comparison
between statements made during hypnosis and those made
under the influence of a sodium-amytal injection. It was
observed, at Para. 91:
"91. Finally, voluntariness is incompatible not only with
promises and threats but actual violence. Had Horvath
made a statement while under the influence of an amytal
injection administered without his consent, the
statement would have been inadmissible because of the
assault, and presumably because also of the effect of the
injection on his mind. There was no physical violence in
the case at bar. There is not even any evidence of bodily
contact between Horvath and Sergeant Proke, but
through the use of an interrogation technique involving
certain physical elements such as a hypnotic quality of
voice and manner, a police officer has gained
unconsented access to what in a human being is of the
68
utmost privacy, the privacy of his own mind. As I have
already indicated, it is my view that this was a form of
violence or intrusion of a moral or mental nature, more
subtle than visible violence but not less efficient in the
result than an amytal injection administered by force."
65. In this regard, the following observations are instructive
for the deciding the questions before us, at Paras. 117,118:
"117. It would appear that hypnosis and narcoanalysis
are used on a consensual basis by certain police forces
as well as by the defence, and it has been argued that
they can serve useful purposes.
118. I refrain from commenting on such practices, short
of noting that even the consensual use of hypnosis and
narcoanalysis for evidentiary purposes may present
problems. Under normal police interrogation, a suspect
has the opportunity to renew or deny his consent to
answer each question, which is no longer the case once
he is, although by consent, in a state of hypnosis or
under the influence of a `truth serum'."
(internal citation omitted)
66. Our attention has also been drawn to the decision reported
as Rock v. Arkansas, 483 US 44 (1987), in which the U.S.
Supreme Court ruled that hypnotically-refreshed testimony
could be admitted as evidence. The constitutional basis for
admitting such testimony was the Sixth Amendment which
gives every person a right to present a defence in criminal
69
cases. However, the crucial aspect was that the trial court had
admitted the oral testimony given during the trial stage rather
than the actual statements made during the hypnosis session
conducted earlier during the investigation stage. It was found
that such hypnotically-refreshed testimony was the only
defence available to the defendant in the circumstances. In
such circumstances, it would of course be open to the
prosecution to contest the reliability of the testimony given
during the trial stage by showing that it had been bolstered by
the statements made during hypnosis. It may be recalled that
a similar line of reasoning had been adopted in United States
v. Solomon, 753 F. 2d 1522 (9th Circ. 1985), where for the
purpose of admissibility of testimony, a distinction had been
drawn between the statements made during a narcoanalysis
interview and the oral testimony given during the trial stage
which was allegedly based on the drug-induced statements.
Hence, the weight of precedents indicates that both the
statements made during narcoanalysis interviews as well as
expert testimony relating to the same have not been given
weightage in criminal trials.
70
Brain Electrical Activation Profile (BEAP) test
67. The third technique in question is the `Brain Electrical
Activation Profile test', also known as the `P300 Waves test'. It
is a process of detecting whether an individual is familiar with
certain information by way of measuring activity in the brain
that is triggered by exposure to selected stimuli. This test
consists of examining and measuring `event-related potentials'
(ERP) i.e. electrical wave forms emitted by the brain after it
has absorbed an external event. An ERP measurement is the
recognition of specific patterns of electrical brain activity in a
subject that are indicative of certain cognitive mental activities
that occur when a person is exposed to a stimulus in the form
of an image or a concept expressed in words. The
measurement of the cognitive brain activity allows the
examiner to ascertain whether the subject recognised stimuli
to which he/she was exposed. [Cited from: Andre A
Moenssens, `Brain Fingerprinting - Can it be used to detect
the innocence of persons charged with a crime?' 70 University
71
of Missouri at Kansas City Law Review 891-920 (Summer
2002) at p. 893]
68. By the late 19th century it had been established that the
brain functioned by emitting electrical impulses and the
technology to measure them was developed in the form of the
electroencephalograph (EEG) which is now commonly used in
the medical field. Brain wave patterns observed through an
EEG scan are fairly crude and may reflect a variety of
unrelated brain activity functions. It was only with the
development of computers that it became possible to sort out
specific wave components on an EEG and identify the
correlation between the waves and specific stimuli. The P300
wave is one such component that was discovered by Dr.
Samuel Sutton in 1965. It is a specific event-related brain
potential (ERP) which is triggered when information relating to
a specific event is recognised by the brain as being significant
or surprising.
72
69. The P300 waves test is conducted by attaching electrodes
to the scalp of the subject, which measure the emission of the
said wave components. The test needs to be conducted in an
insulated and air-conditioned room in order to prevent
distortions arising out of weather conditions. Much like the
narcoanalysis technique and polygraph examination, this test
also requires effective collaboration between the investigators
and the examiner, most importantly for designing the stimuli
which are called `probes'. Ascertaining the subject's familiarity
with the `probes' can help in detecting deception or to gather
useful information. The test subject is exposed to auditory or
visual stimuli (words, sounds, pictures, videos) that are
relevant to the facts being investigated alongside other
irrelevant words and pictures. Such stimuli can be broadly
classified as material `probes' and neutral `probes'. The
underlying theory is that in the case of guilty suspects, the
exposure to the material probes will lead to the emission of
P300 wave components which will be duly recorded by the
instruments. By examining the records of these wave
components the examiner can make inferences about the
73
individual's familiarity with the information related to the
crime. [Refer: Laboratory Procedure Manual - Brain Electrical
Activation Profile (Directorate of Forensic Science, Ministry of
Home Affairs, Government of India, New Delhi - 2005)]
70. The P300 wave test was the precursor to other
neuroscientific techniques such as `Brain Fingerprinting'
developed by Dr. Lawrence Farwell. The latter technique has
been promoted in the context of criminal justice and has
already been the subject of litigation. There is an important
difference between the `P300 waves test' that has been used by
Forensic Science Laboratories in India and the `Brain
Fingerprinting' technique. Dr. Lawrence Farwell has argued
that the P300 wave component is not an isolated sensory
brain effect but it is part of a longer response that continues to
take place after the initial P300 stimulus has occurred. This
extended response bears a correlation with the cognitive
processing that takes place slightly beyond the P300 wave and
continues in the range of 300-800 milliseconds after the
exposure to the stimulus. This extended brain wave
74
component has been named as the MERMER (Memory-and-
Encoding-Related-Multifaceted-Electroencephalographic
Response) effect. [See generally: Lawrence A. Farwell, `Brain
Fingerprinting: A new paradigm in criminal investigations and
counter-terrorism', (2001) Text can be downloaded from
<www.brainwavescience.com>]
71. Functional Magnetic Resonance Imaging (FMRI) is another
neuroscientific technique whose application in the forensic
setting has been contentious. It involves the use of MRI scans
for measuring blood flow between different parts of the brain
which bears a correlation to the subject's truthfulness or
deception. FMRI-based lie-detection has also been advocated
as an aid to interrogations in the context of counter-terrorism
and intelligence operations, but it prompts the same legal
questions that can be raised with respect to all of the
techniques mentioned above. Even though these are non-
invasive techniques the concern is not so much with the
manner in which they are conducted but the consequences for
the individuals who undergo the same. The use of techniques
75
such as `Brain Fingerprinting' and `FMRI-based Lie-Detection'
raise numerous concerns such as those of protecting mental
privacy and the harms that may arise from inferences made
about the subject's truthfulness or familiarity with the facts of
a crime. [See generally: Michael S. Pardo, `Neuroscience
evidence, legal culture and criminal procedure', 33 American
Journal of Criminal Law 301-337 (Summer 2006); Sarah E.
Stoller and Paul Root Wolpe, `Emerging neurotechnologies for
lie detection and the fifth amendment', 33 American Journal of
Law and Medicine 359-375 (2007)]
72. These neuroscientific techniques could also find
application outside the criminal justice setting. For instance,
Henry T. Greely (2005, Cited below) has argued that
technologies that may enable a precise identification of the
subject's mental responses to specific stimuli could potentially
be used for market-research by business concerns for
surveying customer preferences and developing targeted
advertising schemes. They could also be used to judge mental
skills in the educational and employment-related settings
76
since cognitive responses are often perceived to be linked to
academic and professional competence. One can foresee the
potential use of this technique to distinguish between students
and employees on the basis of their cognitive responses. There
are several other concerns with the development of these
`mind-reading' technologies especially those relating to the
privacy of individuals. [Refer: Henry T. Greely, `Chapter 17:
The social effects of advances in neuroscience: Legal problems,
legal perspectives', in Judy Illes (ed.), Neuroethics - Defining
the issues in theory, practice and policy (Oxford University
Press, 2005) at pp. 245-263]
73. Even though the P300 Wave component has been the
subject of considerable research, its uses in the criminal
justice system have not received much scholarly attention. Dr.
Lawrence Farwell's `Brain Fingerprinting' technique has
attracted considerable publicity but has not been the subject
of any rigorous independent study. Besides this preliminary
doubt, an important objection is centred on the inherent
difficulty of designing the appropriate `probes' for the test.
77
Even if the `probes' are prepared by an examiner who is
thoroughly familiar with all aspects of the facts being
investigated, there is always a chance that a subject may have
had prior exposure to the material probes. In case of such
prior exposure, even if the subject is found to be familiar with
the probes, the same will be meaningless in the overall context
of the investigation. For example, in the aftermath of crimes
that receive considerable media-attention the subject can be
exposed to the test stimuli in many ways. Such exposure
could occur by way of reading about the crime in newspapers
or magazines, watching television, listening to the radio or by
word of mouth. A possibility of prior exposure to the stimuli
may also arise if the investigators unintentionally reveal
crucial facts about the crime to the subject before conducting
the test. The subject could also be familiar with the content of
the material probes for several other reasons.
74. Another significant limitation is that even if the tests
demonstrate familiarity with the material probes, there is no
conclusive guidance about the actual nature of the subject's
78
involvement in the crime being investigated. For instance a by-
stander who witnessed a murder or robbery could potentially
be implicated as an accused if the test reveals that the said
person was familiar with the information related to the same.
Furthermore, in cases of amnesia or `memory-hardening' on
part of the subject, the tests could be blatantly misleading.
Even if the inferences drawn from the `P300 wave test' are
used for corroborating other evidence, they could have a
material bearing on a finding of guilt or innocence despite
being based on an uncertain premise. [For an overview of the
limitations of these neuroscientific techniques, see: John G.
New, `If you could read my mind - Implications of neurological
evidence for twenty-first century criminal jurisprudence', 29
Journal of Legal Medicine 179-197 (April-June 2008)]
75. We have come across two precedents relatable to the use
of `Brain Fingerprinting' tests in criminal cases. Since this
technique is considered to be an advanced version of the P300
Waves test, it will be instructive to examine these precedents.
In Harrington v. Iowa, 659 N.W.2d 509 (2003), Terry J.
79
Harrington (appellant) had been convicted for murder in 1978
and the same had allegedly been committed in the course of
an attempted robbery. A crucial component of the
incriminating materials was the testimony of his accomplice.
However, many years later it emerged that the accomplice's
testimony was prompted by an offer of leniency from the
investigating police and doubts were raised about the
credibility of other witnesses as well. Subsequently it was
learnt that at the time of the trial, the police had not shared
with the defence some investigative reports that indicated the
possible involvement of another individual in the said crime.
Harrington had also undergone a `Brain Fingerprinting' test
under the supervision of Dr. Lawrence Farwell. The test
results showed that he had no memories of the `probes'
relating to the act of murder. Hence, Harrington approached
the District Court seeking the vacation of his conviction and
an order for a new trial. Post-conviction relief was sought on
grounds of newly discovered evidence which included
recantation by the prosecution's primary witness, the past
suppression of police investigative reports which implicated
80
another suspect and the results of the `Brain Fingerprinting'
tests. However, the District Court denied this application for
post-conviction relief. This was followed by an appeal before
the Supreme Court of Iowa.
76. The appellate court concluded that Harrington's appeal
was timely and his action was not time barred. The appellant
was granted relief in light of a `due process' violation, i.e. the
failure on part of the prosecution at the time of the original
trial to share the investigative reports with the defence. It was
observed that the defendant's right to a fair trial had been
violated because the prosecution had suppressed evidence
which was favourable to the defendant and clearly material to
the issue of guilt. Hence the case was remanded back to the
District Court. However, the Supreme Court of Iowa gave no
weightage to the results of the `Brain Fingerprinting' test and
did not even inquire into their relevance or reliability. In fact it
was stated: "Because the scientific testing evidence is not
necessary to a resolution of this appeal, we give it no further
consideration." [659 N.W.2d 509, at p. 516]
81
77. The second decision brought to our attention is Slaughter
v. Oklahoma, 105 P. 3d 832 (2005). In that case, Jimmy Ray
Slaughter had been convicted for two murders and sentenced
to death. Subsequently, he filed an application for post-
conviction relief before the Court of Criminal Appeals of
Oklahoma which attempted to introduce in evidence an
affidavit and evidentiary materials relating to a `Brain
Fingerprinting' test. This test had been conducted by Dr.
Lawrence Farwell whose opinion was that the petitioner did
not have knowledge of the `salient features of the crime scene'.
Slaughter also sought a review of the evidence gathered
through DNA testing and challenged the bullet composition
analysis pertaining to the crime scene. However, the appellate
court denied the application for post-conviction relief as well
as the motion for an evidentiary hearing. With regard to the
affidavits based on the `Brain Fingerprinting' test, it was held,
Id. at p. 834:
"10. Dr. Farwell makes certain claims about the Brain
Fingerprinting test that are not supported by anything
other than his bare affidavit. He claims the technique has
82
been extensively tested, has been presented and analyzed
in numerous peer-review articles in recognized scientific
publications, has a very low rate of error, has objective
standards to control its operation, and is generally
accepted within the `relevant scientific community'. These
bare claims, however, without any form of corroboration,
are unconvincing and, more importantly, legally
insufficient to establish Petitioner's post-conviction
request for relief. Petitioner cites one published opinion,
Harrington v. State, 659 N.W.2d 509 (Iowa 2003), in
which a brain fingerprinting test result was raised as
error and discussed by the Iowa Supreme Court (`a novel
computer-based brain testing'). However, while the lower
court in Iowa appears to have admitted the evidence
under non-Daubert circumstances, the test did not
ultimately factor into the Iowa Supreme Court's
published decision in any way."
Accordingly, the following conclusion was stated, Id. at p. 836:
"18. Therefore, based upon the evidence presented, we
find the Brain Fingerprinting evidence is procedurally
barred under the Act and our prior cases, as it could
have been raised in Petitioner's direct appeal and, indeed,
in his first application for post-conviction relief. We
further find a lack of sufficient evidence that would
support a conclusion that Petitioner is factually innocent
or that Brain Fingerprinting, based solely upon the
MERMER effect, would survive a Daubert analysis."
CONTENTIOUS ISSUES IN THE PRESENT CASE
78. As per the Laboratory Procedure manuals, the impugned
tests are being conducted at the direction of jurisdictional
courts even without obtaining the consent of the intended test
83
subjects. In most cases these tests are conducted
conjunctively wherein the veracity of the information revealed
through narcoanalysis is subsequently tested through a
polygraph examination or the BEAP test. In some cases the
investigators could first want to ascertain the capacity of the
subject to deceive (through polygraph examination) or his/her
familiarity with the relevant facts (through BEAP test) before
conducting a narcoanalysis interview. Irrespective of the
sequence in which these techniques are administered, we have
to decide on their permissibility in circumstances where any of
these tests are compulsorily administered, either
independently or conjunctively.
79. It is plausible that investigators could obtain statements
from individuals by threatening them with the possibility of
administering either of these tests. The person being
interrogated could possibly make self-incriminating
statements on account of apprehensions that these techniques
will extract the truth. Such behaviour on part of investigators
is more likely to occur when the person being interrogated is
84
unaware of his/her legal rights or is intimidated for any other
reason. It is a settled principle that a statement obtained
through coercion, threat or inducement is involuntary and
hence inadmissible as evidence during trial. However, it is not
settled whether a statement made on account of the
apprehension of being forcibly subjected to the impugned tests
will be involuntary and hence inadmissible. This aspect merits
consideration. It is also conceivable that an individual who has
undergone either of these tests would be more likely to make
self-incriminating statements when he/she is later confronted
with the results. The question in that regard is whether the
statements that are made subsequently should be admissible
as evidence. The answers to these questions rest on the
permissibility of subjecting individuals to these tests without
their consent.
I. Whether the involuntary administration of the
impugned techniques violates the `right against self-
incrimination' enumerated in Article 20(3) of the
Constitution?
85
80. Investigators could seek reliance on the impugned tests to
extract information from a person who is suspected or accused
of having committed a crime. Alternatively these tests could be
conducted on witnesses to aid investigative efforts. As
mentioned earlier, this could serve several objectives, namely
those of gathering clues which could lead to the discovery of
relevant evidence, to assess the credibility of previous
testimony or even to ascertain the mental state of an
individual. With these uses in mind, we have to decide
whether the compulsory administration of these tests violates
the `right against self-incrimination' which finds place in
Article 20(3) of the Constitution of India. Along with the `rule
against double-jeopardy' and the `rule against retrospective
criminalisation' enumerated in Article 20, it is one of the
fundamental protections that controls interactions between
individuals and the criminal justice system. Article 20(3) reads
as follows:
"No person accused of any offence shall be compelled to
be a witness against himself."
86
81. The interrelationship between the `right against self-
incrimination' and the `right to fair trial' has been recognised
in most jurisdictions as well as international human rights
instruments. For example, the U.S. Constitution incorporates
the `privilege against self-incrimination' in the text of its Fifth
Amendment. The meaning and scope of this privilege has been
judicially moulded by recognising it's interrelationship with
other constitutional rights such as the protection against
`unreasonable search and seizure' (Fourth amendment) and
the guarantee of `due process of law' (Fourteenth amendment).
In the International Covenant on Civil and Political Rights
(ICCPR), Article 14(3)(g) enumerates the minimum guarantees
that are to be accorded during a trial and states that everyone
has a right not to be compelled to testify against himself or to
confess guilt. In the European Convention for the Protection of
Human Rights and Fundamental Freedoms, Article 6(1) states
that every person charged with an offence has a right to a fair
trial and Article 6(2) provides that `Everybody charged with a
criminal offence shall be presumed innocent until proved
guilty according to law'. The guarantee of `presumption of
87
innocence' bears a direct link to the `right against self-
incrimination' since compelling the accused person to testify
would place the burden of proving innocence on the accused
instead of requiring the prosecution to prove guilt.
82. In the Indian context, Article 20(3) should be construed
with due regard for the inter-relationship between rights, since
this approach was recognised in Maneka Gandhi's case,
(1978) 1 SCC 248. Hence, we must examine the `right against
self-incrimination' in respect of its relationship with the
multiple dimensions of `personal liberty' under Article 21,
which include guarantees such as the `right to fair trial' and
`substantive due process'. It must also be emphasized that
Articles 20 and 21 have a non-derogable status within Part III
of our Constitution because the Constitution (Fourty-Fourth
amendment) Act, 1978 mandated that the right to move any
court for the enforcement of these rights cannot be suspended
even during the operation of a proclamation of emergency. In
this regard, Article 359(1) of the Constitution of India reads as
follows:-
88
"359. Suspension of the enforcement of the rights
conferred by Part III during emergencies. - (1) Where a
Proclamation of Emergency is in operation, the President
may by order declare that the right to move any court for
the enforcement of such of the rights conferred by Part III
(except Articles 20 and 21) as may be mentioned in the
order and all proceedings pending in any court for the
enforcement of the rights so mentioned shall remain
suspended for the period during which the Proclamation
is in force or for such shorter period as may be specified
in the order. ..."
83. Undoubtedly, Article 20(3) has an exalted status in our
Constitution and questions about its meaning and scope
deserve thorough scrutiny. In one of the impugned judgments,
it was reasoned that all citizens have an obligation to co-
operate with ongoing investigations. For instance reliance has
been placed on Section 39, CrPC which places a duty on
citizens to inform the nearest magistrate or police officer if
they are aware of the commission of, or of the intention of any
other person to commit the crimes enumerated in the section.
Attention has also been drawn to the language of Section
156(1), CrPC which states that a police officer in charge of a
police station is empowered to investigate cognizable offences
even without an order from the jurisdictional magistrate.
89
Likewise, our attention was drawn to Section 161(1), CrPC
which empowers the police officer investigating a case to orally
examine any person who is supposed to be acquainted with
the facts and circumstances of the case. While the overall
intent of these provisions is to ensure the citizens' cooperation
during the course of investigation, they cannot override the
constitutional protections given to accused persons. The
scheme of the CrPC itself acknowledges this hierarchy between
constitutional and statutory provisions in this regard. For
instance, Section 161(2), CrPC prescribes that when a person
is being examined by a police officer, he is not bound to
answer such questions, the answers of which would have a
tendency to expose him to a criminal charge or a penalty or
forfeiture.
84. Not only does an accused person have the right to refuse
to answer any question that may lead to incrimination, there
is also a rule against adverse inferences being drawn from the
fact of his/her silence. At the trial stage, Section 313(3) of the
CrPC places a crucial limitation on the power of the court to
90
put questions to the accused so that the latter may explain
any circumstances appearing in the evidence against him. It
lays down that the accused shall not render himself/herself
liable to punishment by refusing to answer such questions, or
by giving false answers to them. Further, Proviso (b) to Section
315(1) of CrPC mandates that even though an accused person
can be a competent witness for the defence, his/her failure to
give evidence shall not be made the subject of any comment by
any of the parties or the court or give rise to any presumption
against himself or any person charged together with him at the
trial. It is evident that Section 161(2), CrPC enables a person
to choose silence in response to questioning by a police officer
during the stage of investigation, and as per the scheme of
Section 313(3) and Proviso (b) to Section 315(1) of the same
code, adverse inferences cannot be drawn on account of the
accused person's silence during the trial stage.
Historical origins of the `right against self-incrimination'
85. The right of refusal to answer questions that may
incriminate a person is a procedural safeguard which has
91
gradually evolved in common law and bears a close relation to
the `right to fair trial'. There are competing versions about the
historical origins of this concept. Some scholars have
identified the origins of this right in the medieval period. In
that account, it was a response to the procedure followed by
English judicial bodies such as the Star Chamber and High
Commissions which required defendants and suspects to take
ex officio oaths. These bodies mainly decided cases involving
religious non-conformism in a Protestant dominated society,
as well as offences like treason and sedition. Under an ex
officio oath the defendant was required to answer all questions
posed by the judges and prosecutors during the trial and the
failure to do so would attract punishments that often involved
physical torture. It was the resistance to this practice of
compelling the accused to speak which led to demands for a
`right to silence'.
86. In an academic commentary, Leonard Levy (1969) had
pointed out that the doctrinal origins of the right against self-
incrimination could be traced back to the Latin maxim `Nemo
92
tenetur seipsum prodere' (i.e. no one is bound to accuse
himself) and the evolution of the concept of `due process of
law' enumerated in the Magna Carta. [Refer: Leonard Levy,
`The right against self-incrimination: history and judicial
history', 84(1) Political Science Quarterly 1-29 (March 1969)]
The use of the ex officio oath by the ecclesiastical courts in
medieval England had come under criticism from time to time,
and the most prominent cause for discontentment came with
its use in the Star Chamber and the High Commissions. Most
scholarship has focussed on the sedition trial of John Lilburne
(a vocal critic of Charles I, the then monarch) in 1637, when
he refused to answer questions put to him on the ground that
he had not been informed of the contents of the written
complaint against him. John Lilburne went on to vehemently
oppose the use of ex-officio oaths, and the Parliament of the
time relented by abolishing the Star Chamber and the High
Commission in 1641. This event is regarded as an important
landmark in the evolution of the `right to silence'.
93
87. However, in 1648 a special committee of Parliament
conducted an investigation into the loyalty of members whose
opinions were offensive to the army leaders. The committee's
inquisitional conduct and its requirement that witnesses take
an oath to tell the truth provoked opponents to condemn what
they regarded as a revival of Star Chamber tactics. John
Lilburne was once again tried for treason before this
committee, this time for his outspoken criticism of the leaders
who had prevailed in the struggle between the supporters of
the monarch and those of the Parliament in the English civil
war. John Lilburne invoked the spirit of the Magna Carta as
well as the 1628 Petition of Right to argue that even after
common-law indictment and without oath, he did not have to
answer questions against or concerning himself. He drew a
connection between the right against self-incrimination and
the guarantee of a fair trial by invoking the idea of `due
process of law' which had been stated in the Magna Carta.
88. John H. Langbein (1994) has offered more historical
insights into the emergence of the `right to silence'. [John H.
94
Langbein, `The historical origins of the privilege against self-
incrimination at common law', 92(5) Michigan Law Review
1047-1085 (March 1994)] He draws attention to the fact that
even though ex officio oaths were abolished in 1641, the
practice of requiring defendants to present their own defence
in criminal proceedings continued for a long time thereafter.
The Star Chamber and the High Commissions had mostly
tried cases involving religious non-conformists and political
dissenters, thereby attracting considerable criticism. Even
after their abolition, the defendants in criminal courts did not
have the right to be represented by a lawyer (`right to counsel')
or the right to request the presence of defence witnesses (`right
of compulsory process'). Hence, defendants were more or less
compelled to testify on their own behalf. Even though the
threat of physical torture on account of remaining silent had
been removed, the defendant would face a high risk of
conviction if he/she did not respond to the charges by
answering the material questions posed by the judge and the
prosecutor. In presenting his/her own defence during the trial,
there was a strong likelihood that the contents of such
95
testimony could strengthen the case of the prosecution and
lead to conviction. With the passage of time, the right of a
criminal defendant to be represented by a lawyer eventually
emerged in the common law tradition. A watershed in this
regard was the Treason Act of 1696 which provided for a `right
to counsel' as well as `compulsory process' in cases involving
offences such as treason. Gradually, the right to be defended
by a counsel was extended to more offences, but the role of the
counsel was limited in the early years. For instance defence
lawyers could only help their clients with questions of law and
could not make submissions related to the facts.
89. The practice of requiring the accused persons to narrate or
contest the facts on their own corresponds to a prominent
feature of an inquisitorial system, i.e. the testimony of the
accused is viewed as the `best evidence' that can be gathered.
The premise behind this is that innocent persons should not
be reluctant to testify on their own behalf. This approach was
followed in the inquisitional procedure of the ecclesiastical
courts and had thus been followed in other courts as well. The
96
obvious problem with compelling the accused to testify on his
own behalf is that an ordinary person lacks the legal training
to effectively respond to suggestive and misleading
questioning, which could come from the prosecutor or the
judge. Furthermore, even an innocent person is at an inherent
disadvantage in an environment where there may be
unintentional irregularities in the testimony. Most importantly
the burden of proving innocence by refuting the charges was
placed on the defendant himself. In the present day, the
inquisitorial conception of the defendant being the best source
of evidence has long been displaced with the evolution of
adversarial procedure in the common law tradition. Criminal
defendants have been given protections such as the
presumption of innocence, right to counsel, the right to be
informed of charges, the right of compulsory process and the
standard of proving guilt beyond reasonable doubt among
others. It can hence be stated that it was only with the
subsequent emergence of the `right to counsel' that the
accused's `right to silence' became meaningful. With the
consolidation of the role of defence lawyers in criminal trials, a
97
clear segregation emerged between the testimonial function
performed by the accused and the defensive function
performed by the lawyer. This segregation between the
testimonial and defensive functions is now accepted as an
essential feature of a fair trial so as to ensure a level-playing
field between the prosecution and the defence. In addition to a
defendant's `right to silence' during the trial stage, the
protections were extended to the stage of pre-trial inquiry as
well. With the enactment of the Sir John Jervis Act of 1848,
provisions were made to advise the accused that he might
decline to answer questions put to him in the pre-trial inquiry
and to caution him that his answers to pre-trial interrogation
might be used as evidence against him during the trial stage.
90. The judgment in Nandini Satpathy v. P.L. Dani, (1978) 2
SCC 424, at pp. 438-439, referred to the following extract from
a decision of the US Supreme Court in Brown v. Walker, 161
US 591 (1896), which had later been approvingly cited by
Warren, C.J. in Miranda v. Arizona, 384 US 436 (1966):
98
"The maxim nemo tenetur seipsum accusare had its origin
in a protest against the inquisitorial and manifestly
unjust methods of interrogating accused persons, which
have long obtained in the continental system, and, until
the expulsion of the Stuarts from the British throne in
1688, and the erection of additional barriers for the
protection of the people against the exercise of arbitrary
power, were not uncommon even in England. While the
admissions or confessions of the prisoner, when
voluntarily and freely made, have always ranked high in
the scale of incriminating evidence, if an accused person
be asked to explain his apparent connection with a crime
under investigation, the case with which the questions
put to him may assume an inquisitorial character, the
temptation to press the witness unduly, to browbeat him
if he be timid or reluctant, to push him into a corner, and
to entrap him into fatal contradictions, which is so
painfully evident in many of the earlier state trials,
notably in those of Sir Nicholas Throckmorton, and Udal,
the Puritan minister, made the system so odious as to
give rise to a demand for its total abolition. The change in
the English criminal procedure in that particular seems
to be founded upon no statute and no judicial opinion,
but upon a general and silent acquiescence of the courts
in a popular demand. But, however adopted, it has
become firmly embedded in English, as well as in
American jurisprudence. So deeply did the inequities of
the ancient system impress themselves upon the minds
of the American colonists that the State, with one accord,
made a denial of the right to question an accused person
a part of their fundamental law, so that a maxim, which
in England was a mere rule of evidence, became clothed
in this country with the impregnability of a constitutional
enactment."
99
Underlying rationale of the right against self-incrimination
91. As mentioned earlier, `the right against self-incrimination'
is now viewed as an essential safeguard in criminal procedure.
Its underlying rationale broadly corresponds with two
objectives - firstly, that of ensuring reliability of the
statements made by an accused, and secondly, ensuring that
such statements are made voluntarily. It is quite possible that
a person suspected or accused of a crime may have been
compelled to testify through methods involving coercion,
threats or inducements during the investigative stage. When a
person is compelled to testify on his/her own behalf, there is a
higher likelihood of such testimony being false. False
testimony is undesirable since it impedes the integrity of the
trial and the subsequent verdict. Therefore, the purpose of the
`rule against involuntary confessions' is to ensure that the
testimony considered during trial is reliable. The premise is
that involuntary statements are more likely to mislead the
judge and the prosecutor, thereby resulting in a miscarriage of
justice. Even during the investigative stage, false statements
100
are likely to cause delays and obstructions in the investigation
efforts.
92. The concerns about the `voluntariness' of statements allow
a more comprehensive account of this right. If involuntary
statements were readily given weightage during trial, the
investigators would have a strong incentive to compel such
statements - often through methods involving coercion,
threats, inducement or deception. Even if such involuntary
statements are proved to be true, the law should not
incentivise the use of interrogation tactics that violate the
dignity and bodily integrity of the person being examined. In
this sense, `the right against self-incrimination' is a vital
safeguard against torture and other `third-degree methods'
that could be used to elicit information. It serves as a check on
police behaviour during the course of investigation. The
exclusion of compelled testimony is important, otherwise the
investigators will be more inclined to extract information
through such compulsion as a matter of course. The frequent
reliance on such `short-cuts' will compromise the diligence
101
required for conducting meaningful investigations. During the
trial stage, the onus is on the prosecution to prove the charges
levelled against the defendant and the `right against self-
incrimination' is a vital protection to ensure that the
prosecution discharges the said onus.
93. These concerns have been recognised in Indian as well as
foreign judicial precedents. For instance, Das Gupta, J. had
observed in State of Bombay v. Kathi Kalu Oghad, [1962] 3
SCR 10, at pp. 43-44:
"... for long it has been generally agreed among those who
have devoted serious thought to these problems that few
things could be more harmful to the detection of crime or
conviction of the real culprit, few things more likely to
hamper the disclosure of truth than to allow investigators
or prosecutors to slide down the easy path of producing
by compulsion, evidence, whether oral or documentary,
from an accused person. It has been felt that the
existence of such an easy way would tend to dissuade
persons in charge of investigation or prosecution from
conducting diligent search for reliable independent
evidence and from sifting of available materials with the
care necessary for ascertainment of truth. If it is
permissible in law to obtain evidence from the accused
person by compulsion, why tread the hard path of
laborious investigation and prolonged examination of
other men, materials and documents? It has been well
said that an abolition of this privilege would be an
incentive for those in charge of enforcement of law `to sit
102
comfortably in the shade rubbing red pepper into a poor
devils' eyes rather than to go about in the sun hunting
up evidence.' [Sir James Fitzjames Stephen, History of
Criminal Law, p. 442] No less serious is the danger that
some accused persons at least, may be induced to
furnish evidence against themselves which is totally false
- out of sheer despair and an anxiety to avoid an
unpleasant present. Of all these dangers the Constitution
makers were clearly well aware and it was to avoid them
that Article 20(3) was put in the Constitution."
94. The rationale behind the Fifth Amendment in the U.S.
Constitution was eloquently explained by Goldberg. J. in
Murphy v. Waterfront Commission, 378 US 52 (1964), at p.
55:
"It reflects many of our fundamental values and most
noble aspirations: our unwillingness to subject those
suspected of crime to the cruel trilemma of self-
accusation, perjury or contempt; our preference for an
accusatorial rather than an inquisitorial system of
criminal justice; our fear that self-incriminating
statements will be elicited by inhumane treatment and
abuses; our sense of fair play which dictates a fair state-
individual balance by requiring the government to leave
the individual alone until good cause is shown for
disturbing him and by requiring the government in its
contests with the individual to shoulder the entire load;
our respect for the inviolability of the human personality
and of the right of each individual to a private enclave
where he may lead a private life; our distrust of self-
deprecatory statements; and our realization that the
privilege, while sometimes a shelter to the guilty, is often
a protection to the innocent."
103
A similar view was articulated by Lord Hailsham of St.
Marylebone in Wong Kam-ming v. R , [1979] 1 All ER 939, at
p. 946 :
"... any civilised system of criminal jurisprudence must
accord to the judiciary some means of excluding
confessions or admissions obtained by improper
methods. This is not only because of the potential
unreliability of such statements, but also, and perhaps
mainly, because in a civilised society it is vital that
persons in custody or charged with offences should not
be subjected to ill treatment or improper pressure in
order to extract confessions. It is therefore of very great
importance that the courts should continue to insist that
before extra-judicial statements can be admitted in
evidence the prosecution must be made to prove beyond
reasonable doubt that the statement was not obtained in
a manner which should be reprobated and was therefore
in the truest sense voluntary."
95. V.R. Krishna Iyer, J. echoed similar concerns in Nandini
Satpathy's case, (1978) 2 SCC 424, at p. 442:
"...And Article 20(3) is a human article, a guarantee of
dignity and integrity and of inviolability of the person and
refusal to convert an adversary system into an
inquisitorial scheme in the antagonistic ante-chamber of
a police station. And in the long run, that investigation is
best which uses stratagems least, that policeman
deserves respect who gives his fists rest and his wits
restlessness. The police are part of us and must rise in
people's esteem through firm and friendly, not foul and
sneaky strategy."
104
96. In spite of the constitutionally entrenched status of the
right against self-incrimination, there have been some
criticisms of the policy underlying the same. John Wigmore
(1960) argued against a broad view of the privilege which
extended the same to the investigative stage. [Refer: John
Wigmore, `The privilege against self-incrimination, its
constitutional affectation, raison d'etre and miscellaneous
implications', 51 Journal of Criminal Law, Criminology and
Police Science 138 (1960)] He has asserted that the doctrinal
origins of the `rule against involuntary confessions' in evidence
law and those of the `right to self-incrimination' were entirely
different and catered to different objectives. In the learned
author's opinion, the `rule against involuntary confessions'
evolved on account of the distrust of statements made in
custody. The objective was to prevent these involuntary
statements from being considered as evidence during trial but
there was no prohibition against relying on statements made
involuntarily during investigation. Wigmore argued that the
privilege against self-incrimination should be viewed as a right
that was confined to the trial stage, since the judge can
105
intervene to prevent an accused from revealing incriminating
information at that stage, while similar oversight is not always
possible during the pre-trial stage.
97. In recent years, scholars such as David Dolinko (1986),
Akhil Reed Amar (1997) and Mike Redmayne (2007) among
others have encapsulated the objections to the scope of this
right. [See: David Dolinko, `Is There a Rationale for the
Privilege Against Self-Incrimination?', 33 University of
California Los Angeles Law Review 1063 (1986); Akhil Reed
Amar, The Constitution and Criminal Procedure: First Principles
(New Haven: Yale University Press, 1997) at pp. 65-70; Mike
Redmayne, `Re-thinking the Privilege against Self-
incrimination', 27 Oxford Journal of Legal Studies 209-232
(Summer 2007)] It is argued that in aiming to create a fair
state-individual balance in criminal cases, the task of the
investigators and prosecutors is made unduly difficult by
allowing the accused to remain silent. If the overall intent of
the criminal justice system is to ensure public safety through
expediency in investigations and prosecutions, it is urged that
106
the privilege against self-incrimination protects the guilty at
the cost of such utilitarian objectives. Another criticism is that
adopting a broad view of this right does not deter improper
practices during investigation and it instead encourages
investigators to make false representations to courts about the
voluntary or involuntary nature of custodial statements. It is
reasoned that when investigators are under pressure to deliver
results there is an inadvertent tendency to rely on methods
involving coercion, threats, inducement or deception in spite of
the legal prohibitions against them. Questions have also been
raised about conceptual inconsistencies in the way that courts
have expanded the scope of this right. One such objection is
that if the legal system is obliged to respect the mental privacy
of individuals, then why is there no prohibition against
compelled testimony in civil cases which could expose parties
to adverse consequences. Furthermore, questions have also
been asked about the scope of the privilege being restricted to
testimonial acts while excluding physical evidence which can
be extracted through compulsion.
107
98. In response to John Wigmore's thesis about the separate
foundations of the `rule against involuntary confessions', we
must recognise the infusion of constitutional values into all
branches of law, including procedural areas such as the law of
evidence. While the above-mentioned criticisms have been
made in academic commentaries, we must defer to the judicial
precedents that control the scope of Article 20(3). For instance,
the interrelationship between the privilege against self-
incrimination and the requirements of observing due process
of law were emphasized by William Douglas, J. in Rochin v.
California, 342 US 166 (1951), at p. 178:
"As an original matter it might be debatable whether the
provision in the Fifth Amendment that no person `shall
be compelled in any criminal case to be a witness against
himself' serves the ends of justice. Not all civilized legal
procedures recognize it. But the choice was made by the
framers, a choice which sets a standard for legal trials in
this country. The Framers made it a standard of due
process for prosecutions by the Federal Government. If it
is a requirement of due process for a trial in the federal
courthouse, it is impossible for me to say it is not a
requirement of due process for a trial in the state
courthouse."
108
I-A. Whether the investigative use of the impugned
techniques creates a likelihood of incrimination for the
subject?
99. The respondents have submitted that the compulsory
administration of the impugned tests will only be sought to
boost investigation efforts and that the test results by
themselves will not be admissible as evidence. The next prong
of this position is that if the test results enable the
investigators to discover independent materials that are
relevant to the case, such subsequently discovered materials
should be admissible during trial. In order to evaluate this
position, we must answer the following questions:
7 Firstly, we should clarify the scope of the `right against
self-incrimination' - i.e. whether it should be construed
as a broad protection that extends to the investigation
stage or should it be viewed as a narrower right confined
to the trial stage?
7 Secondly, we must examine the ambit of the words
`accused of any offence' in Article 20(3) - i.e. whether the
109
protection is available only to persons who are formally
accused in criminal cases, or does it extend to include
suspects and witnesses as well as those who apprehend
incrimination in cases other than the one being
investigated?
7 Thirdly, we must evaluate the evidentiary value of
independent materials that are subsequently discovered
with the help of the test results. In light of the `theory of
confirmation by subsequent facts' incorporated in Section
27 of the Indian Evidence Act, 1872 we need to examine
the compatibility between this section and Article 20(3).
Of special concern are situations when persons could be
compelled to reveal information which leads to the
discovery of independent materials. To answer this
question, we must clarify what constitutes `incrimination'
for the purpose of invoking Article 20(3).
Applicability of Article 20(3) to the stage of investigation
100. The question of whether Article 20(3) should be narrowly
construed as a trial right or a broad protection that extends to
110
the stage of investigation has been conclusively answered by
our Courts. In M.P. Sharma v. Satish Chandra, [1954] SCR
1077, it was held by Jagannadhadas, J. at pp. 1087-1088:
"Broadly stated, the guarantee in Article 20(3) is against
`testimonial compulsion'. It is suggested that this is
confined to the oral evidence of a person standing his
trial for an offence when called to the witness-stand. We
can see no reason to confine the content of the
constitutional guarantee to this barely literal import. So
to limit it would be to rob the guarantee of its substantial
purpose and to miss the substance for the sound as
stated in certain American decisions. ..."
"Indeed, every positive volitional act which furnished
evidence is testimony, and testimonial compulsion
connotes coercion which procures the positive volitional
evidentiary acts of the person, as opposed to the negative
attitude of silence or submission on his part. Nor is there
any reason to think that the protection in respect of the
evidence so procured is confined to what transpires at
the trial in the court room. The phrase used in Article
20(3) is `to be a witness' and not to `appear as a witness':
It follows that the protection afforded to an accused in so
far as it is related to the phrase `to be a witness' is not
merely in respect of testimonial compulsion in the court
room but may well extend to compelled testimony
previously obtained from him. It is available therefore to
a person against whom a formal accusation relating to
the commission of an offence has been levelled which in
the normal course may result in prosecution. Whether it
is available to other persons in other situations does not
call for decision in this case."
111
101. These observations were cited with approval by B.P.
Sinha, C.J. in State of Bombay v. Kathi Kalu Oghad &
Others, [1962] 3 SCR 10, at pp. 26-28. In the minority
opinion, Das Gupta, J. affirmed the same position, Id. at p. 40:
"... If the protection was intended to be confined to being
a witness in Court then really it would have been an idle
protection. It would be completely defeated by compelling
a person to give all the evidence outside court and then,
having what he was so compelled to do proved in court
through other witnesses. An interpretation which so
completely defeats the constitutional guarantee cannot,
of course, be correct. The contention that the protection
afforded by Article 20(3) is limited to the stage of trial
must therefore be rejected."
102. The broader view of Article 20(3) was consolidated in
Nandini Satpathy v. P.L. Dani, (1978) 2 SCC 424:
"... Any giving of evidence, any furnishing of information,
if likely to have an incriminating impact, answers the
description of being a witness against oneself. Not being
limited to the forensic stage by express words in Article
20(3), we have to construe the expression to apply to
every stage where furnishing of information and
collection of materials takes place. That is to say, even
the investigation at the police level is embraced by Article
20(3).This is precisely what Section 161(2) means. That
sub-section relates to oral examination by police officers
and grants immunity at that stage. Briefly, the
Constitution and the Code are coterminus in the
protective area. While the code may be changed, the
Constitution is more enduring. Therefore, we have to
base our conclusion not merely upon Section 161(2) but
112
on the more fundamental protection, although equal in
ambit, contained in Article 20(3)."
(at p. 435)
"If the police can interrogate to the point of self-
accusation, the subsequent exclusion of that evidence at
the trial hardly helps because the harm has already been
done. The police will prove through other evidence what
they have procured through forced confession. So it is
that the foresight of the framers has pre-empted self-
incrimination at the incipient stages by not expressly
restricting it to the trial stage in court. True, compelled
testimony previously obtained is excluded. But the
preventive blow falls also on pre-court testimonial
compulsion. The condition, as the decisions now go, is
that the person compelled must be an accused. Both
precedent procurement and subsequent exhibition of
self-incriminating testimony are obviated by intelligent
constitutional anticipation." (at p. 449)
103. In upholding this broad view of Article 20(3), V.R.
Krishna Iyer, J. relied heavily on the decision of the US
Supreme Court in Ernesto Miranda v. Arizona, 384 US 436
(1966). The majority opinion (by Earl Warren, C.J.) laid down
that custodial statements could not be used as evidence
unless the police officers had administered warnings about the
accused's right to remain silent. The decision also recognised
the right to consult a lawyer prior to and during the course of
custodial interrogations. The practice promoted by this case is
113
that it is only after a person has `knowingly and intelligently'
waived of these rights after receiving a warning that the
statements made thereafter can be admitted as evidence. The
safeguards were prescribed in the following manner, Id. at pp.
444-445:
"... the prosecution may not use statements, whether
exculpatory or inculpatory, stemming from custodial
interrogation of the defendant unless it demonstrates the
use of procedural safeguards effective to secure the
privilege against self-incrimination. By custodial
interrogation, we mean questioning initiated by law
enforcement officers after a person has been taken into
custody or otherwise deprived of his freedom of action in
any significant way. [...] As for the procedural safeguards
to be employed, unless other fully effective means are
devised to inform accused persons of their right of silence
and to assure a continuous opportunity to exercise it, the
following measures are required. Prior to any
questioning, the person must be warned that he has a
right to remain silent, that any statement he does make
may be used as evidence against him, and that he has a
right to the presence of an attorney, either retained or
appointed. The defendant may waive effectuation of these
rights, provided the waiver is made voluntarily,
knowingly and intelligently. If, however, he indicates in
any manner and at any stage of the process that he
wishes to consult with an attorney before speaking there
can be no questioning. Likewise, if the individual is alone
and indicates in any manner that he does not wish to be
interrogated, the police may not question him. The mere
fact that he may have answered some questions or
volunteered some statements on his own does not deprive
him of the right to refrain from answering any further
114
inquiries until he has consulted with an attorney and
thereafter consents to be questioned."
104. These safeguards were designed to mitigate the
disadvantages faced by a suspect in a custodial environment.
This was done in recognition of the fact that methods involving
deception and psychological pressure were routinely used and
often encouraged in police interrogations. Emphasis was
placed on the ability of the person being questioned to fully
comprehend and understand the content of the stipulated
warning. It was held, Id. at pp. 457-458:
"In these cases, we might not find the defendant's
statements to have been involuntary in traditional terms.
Our concern for adequate safeguards to protect the
precious Fifth Amendment right is, of course, not
lessened in the slightest. In each of the cases, the
defendant was thrust into an unfamiliar atmosphere and
run through menacing police interrogation procedures. ...
It is obvious that such an interrogation environment is
created for no purpose other than to subjugate the
individual to the will of his examiner. This atmosphere
carried its own badge of intimidation. To be sure, this is
not physical intimidation, but it is equally destructive of
human dignity. [Professor Sutherland, `Crime and
Confessions', 79 Harvard Law Review 21, 37 (1965)] The
current practice of incommunicado interrogation is at
odds with one of our Nation's most cherished principles -
that the individual may not be compelled to incriminate
himself. Unless adequate protective devices are employed
to dispel the compulsion inherent in custodial
115
surroundings, no statement obtained from the defendant
can truly be the product of his free choice."
105. The opinion also explained the significance of having a
counsel present during a custodial interrogation. It was noted,
Id. at pp. 469-470:
"The circumstances surrounding in-custody interrogation
can operate very quickly to overbear the will of one
merely made aware of his privilege by his interrogators.
Therefore, the right to have counsel present at the
interrogation is indispensable to the protection of the
Fifth Amendment privilege under the system we delineate
today. Our aim is to assure that the individual's right to
choose between silence and speech remains unfettered
throughout the interrogation process. A once-stated
warning, delivered by those who will conduct the
interrogation, cannot itself suffice to that end among
those who most require knowledge of their rights. A mere
warning given by the interrogators is not alone sufficient
to accomplish that end. Prosecutors themselves claim
that the admonishment of the right to remain silent
without more `will benefit only the recidivist and the
professional.' [Brief for the National District Attorneys
Association as amicus curiae, p. 14] Even preliminary
advice given to the accused by his own attorney can be
swiftly overcome by the secret interrogation process.
[Cited from Escobedo v. State of Illinois, 378 U.S. 478,
485 ...] Thus, the need for counsel to protect the Fifth
Amendment privilege comprehends not merely a right to
consult with counsel prior to questioning, but also to
have counsel present during any questioning if the
defendant so desires."
116
106. The majority decision in Miranda (supra.) was not a
sudden development in U.S. constitutional law. The scope of
the privilege against self-incrimination had been progressively
expanded in several prior decisions. The notable feature was
the recognition of the interrelationship between the Fifth
Amendment and the Fourteenth Amendment's guarantee that
the government must observe the `due process of law' as well
as the Fourth Amendment's protection against `unreasonable
search and seizure'. While it is not necessary for us to survey
these decisions, it will suffice to say that after Miranda
(supra.), administering a warning about a person's right to
silence during custodial interrogations as well as obtaining a
voluntary waiver of the prescribed rights has become a
ubiquitous feature in the U.S. criminal justice system. In the
absence of such a warning and voluntary waiver, there is a
presumption of compulsion with regard to the custodial
statements, thereby rendering them inadmissible as evidence.
The position in India is different since there is no automatic
presumption of compulsion in respect of custodial statements.
117
However, if the fact of compulsion is proved then the resulting
statements are rendered inadmissible as evidence.
Who can invoke the protection of Article 20(3)?
107. The decision in Nandini Satpathy's case, (supra.) also
touched on the question of who is an `accused' for the purpose
of invoking Article 20(3). This question had been left open in
M.P. Sharma's case (supra.). Subsequently, it was addressed
in Kathi Kalu Oghad (supra.), at p. 37:
"To bring the statement in question within the
prohibition of Article 20(3), the person accused must
have stood in the character of an accused person at the
time he made the statement. It is not enough that he
should become an accused, anytime after the statement
has been made."
108. While there is a requirement of formal accusation for a
person to invoke Article 20(3) it must be noted that the
protection contemplated by Section 161(2), CrPC is wider.
Section 161(2) read with 161(1) protects `any person supposed
to be acquainted with the facts and circumstances of the case'
in the course of examination by the police. The language of
this provision is as follows:
118
161. Examination of witnesses by police.
(1) Any police officer making an investigation under this
Chapter, or any police officer not below such rank as the
State Government may, by general or special order,
prescribe in this behalf, acting on the requisition of such
officer, may examine orally any person supposed to be
acquainted with the facts and circumstances of the case.
(2) Such person shall be bound to answer truly all
questions relating to such case put to him by such
officer, other than questions the answers to which would
have a tendency to expose him to a criminal charge or to
a penalty or forfeiture.
(3) The police officer may reduce into writing any
statement made to him in the course of an examination
under this section; and if he does so, he shall make a
separate and true record of the statement of each such
person whose statement he records.
109. Therefore the `right against self-incrimination' protects
persons who have been formally accused as well as those who
are examined as suspects in criminal cases. It also extends to
cover witnesses who apprehend that their answers could
expose them to criminal charges in the ongoing investigation
or even in cases other than the one being investigated.
Krishna Iyer, J. clarified this position, (1978) 2 SCC 424, at p.
435:
"The learned Advocate General, influenced by American
decisions rightly agreed that in expression Section 161(2)
of the Code might cover not merely accusations already
registered in police stations but those which are likely to
119
be the basis for exposing a person to a criminal charge.
Indeed, this wider construction, if applicable to Article
20(3), approximates the constitutional clause to the
explicit statement of the prohibition in Section 161(2).
This latter provision meaningfully uses the expression
`expose himself to a criminal charge'. Obviously, these
words mean, not only cases where the person is already
exposed to a criminal charge but also instances which
will imminently expose him to criminal charges."
It was further observed, Id. at pp. 451-452 (Para. 50):
"... `To be a witness against oneself' is not confined to the
particular offence regarding which the questioning is
made but extends to other offences about which the
accused has reasonable apprehension of implication from
his answer. This conclusion also flows from `tendency to
be exposed to a criminal charge'. A `criminal charge'
covers any criminal charge then under investigation or
trial or which imminently threatens the accused."
110. Even though Section 161(2) of the CrPC casts a wide
protective net to protect the formally accused persons as well
as suspects and witnesses during the investigative stage,
Section 132 of the Evidence Act limits the applicability of this
protection to witnesses during the trial stage. The latter
provision provides that witnesses cannot refuse to answer
questions during a trial on the ground that the answers could
incriminate them. However, the proviso to this section
stipulates that the content of such answers cannot expose the
120
witness to arrest or prosecution, except for a prosecution for
giving false evidence. Therefore, the protection accorded to
witnesses at the stage of trial is not as wide as the one
accorded to the accused, suspects and witnesses during
investigation [under Section 161(2), CrPC]. Furthermore, it is
narrower than the protection given to the accused during the
trial stage [under Section 313(3) and Proviso (b) to Section
315(1), CrPC]. The legislative intent is to preserve the fact-
finding function of a criminal trial. Section 132 of the Evidence
Act reads:-
"132. Witness not excused from answering on ground
that answer will criminate. - A witness shall not be
excused from answering any question as to any matter
relevant to the matter in issue in any suit or in any civil
or criminal proceeding, upon the ground that the answer
to such question will criminate, or may tend directly or
indirectly to criminate, such witness, or that it will
expose, or tend directly or indirectly to expose, such
witness to a penalty or forfeiture of any kind.
Proviso. - Provided that no such answer, which a witness
shall be compelled to give, shall subject him to any arrest
or prosecution, or be proved against him in any criminal
proceeding, except a prosecution for giving false evidence
by such answer."
121
111. Since the extension of the `right against self-
incrimination' to suspects and witnesses has its basis in
Section 161(2), CrPC it is not readily available to persons who
are examined during proceedings that are not governed by the
code. There is a distinction between proceedings of a purely
criminal nature and those proceedings which can culminate in
punitive remedies and yet cannot be characterised as criminal
proceedings. The consistent position has been that ordinarily
Article 20(3) cannot be invoked by witnesses during
proceedings that cannot be characterised as criminal
proceedings. In administrative and quasi-criminal
proceedings, the protection of Article 20(3) becomes available
only after a person has been formally accused of committing
an offence. For instance in Raja Narayanlal Bansilal v.
Maneck Phiroz Mistry, [1961] 1 SCR 417, the contention
related to the admissibility of a statement made before an
inspector who was appointed under the Companies Act, 1923
to investigate the affairs of a company and report thereon. It
had to be decided whether the persons who were examined by
122
the concerned inspector could claim the protection of Article
20(3). The question was answered, Id. at p. 438:
"The scheme of the relevant sections is that the
investigation begins broadly with a view to examine the
management of the affairs of the company to find out
whether any irregularities have been committed or not. In
such a case there is no accusation, either formal or
otherwise, against any specified individual; there may be
a general allegation that the affairs are irregularly,
improperly or illegally managed ; but who would be
responsible for the affairs which are reported to be
irregularly managed is a matter which would be
determined at the end of the enquiry. At the
commencement of the enquiry and indeed throughout its
proceedings there is no accused person, no accuser, and
no accusation against anyone that he has committed an
offence. In our opinion a general enquiry and
investigation into the affairs of the company thus
contemplated cannot be regarded as an investigation
which starts with an accusation contemplated in Article
20(3) of the Constitution. ..."
112. A similar issue arose for consideration in Romesh
Chandra Mehta v. State of West Bengal, [1969] 2 SCR 461,
wherein it was held, at p. 472:
"Normally a person stands in the character of an accused
when a First Information Report is lodged against him in
respect of an offence before an officer competent to
investigate it, or when a complaint is made relating to the
commission of an offence before a Magistrate competent
to try or send to another Magistrate for trial of the
offence. Where a Customs Officer arrests a person and
informs that person of the grounds of his arrest, [which
123
he is bound to do under Article 22(1) of the Constitution]
for the purpose of holding an inquiry into the
infringement of the provisions of the Sea Customs Act
which he has reason to believe has taken place, there is
no formal accusation of an offence. In the case of an
offence by infringement of the Sea Customs Act which is
punishable at the trial before a Magistrate, there is an
accusation when a complaint is lodged by an officer
competent in that behalf before the Magistrate."
113. In Balkishan A. Devidayal v. State of Maharashtra,
(1980) 4 SCC 600, one of the contentious issues was whether
the statements recorded by a Railway Police Force (RPF) officer
during an inquiry under the Railway Property (Unlawful
Possession) Act, 1996 would attract the protection of Article
20(3). Sarkaria, J. held that such an inquiry was substantially
different from an investigation contemplated under the CrPC,
and therefore formal accusation was a necessary condition for
a person to claim the protection of Article 20(3). It was
observed, Id. at p. 623:
"To sum up, only a person against whom a formal
accusation of the commission of an offence has been
made can be a person `accused of an offence' within the
meaning of Article 20(3). Such formal accusation may be
specifically made against him in an FIR or a formal
complaint or any other formal document or notice served
on that person, which ordinarily results in his
prosecution in court. In the instant case no such formal
124
accusation has been made against the appellant when
his statements in question were recorded by the RPF
Officer."
What constitutes `incrimination' for the purpose of Article
20(3)?
114. We can now examine the various circumstances that
could `expose a person to criminal charges'. The scenario
under consideration is one where a person in custody is
compelled to reveal information which aids the investigation
efforts. The information so revealed can prove to be
incriminatory in the following ways:
7 The statements made in custody could be directly relied
upon by the prosecution to strengthen their case.
However, if it is shown that such statements were made
under circumstances of compulsion, they will be
excluded from the evidence.
7 Another possibility is that of `derivative use', i.e. when
information revealed during questioning leads to the
discovery of independent materials, thereby furnishing a
125
link in the chain of evidence gathered by the
investigators.
7 Yet another possibility is that of `transactional use', i.e.
when the information revealed can prove to be helpful for
the investigation and prosecution in cases other than the
one being investigated.
7 A common practice is that of extracting materials or
information, which are then compared with materials
that are already in the possession of the investigators.
For instance, handwriting samples and specimen
signatures are routinely obtained for the purpose of
identification or corroboration.
115. The decision in Nandini Satpathy's case (supra.) sheds
light on what constitutes incrimination for the purpose of
Article 20(3). Krishna Iyer, J. observed, at pp. 449-450:
"In this sense, answers that would in themselves support
a conviction are confessions but answers which have a
reasonable tendency strongly to point out to the guilt of
the accused are incriminatory. Relevant replies which
furnish a real and clear link in the chain of evidence
indeed to bind down the accused with the crime become
126
incriminatory and offend Article 20(3) if elicited by
pressure from the mouth of the accused. ...
An answer acquires confessional status only if, in terms
or substantially, all the facts which constitute the offence
are admitted by the offender. If his statement also
contains self-exculpatory matter it ceases to be a
confession. Article 20(3) strikes at confessions and self-
incriminations but leaves untouched other relevant
facts."
116. Reliance was also placed on the decision of the US
Supreme Court in Samuel Hoffman v. United States, 341 US
479 (1951). The controversy therein was whether the privilege
against self-incrimination was available to a person who was
called on to testify as a witness in a grand-jury investigation.
Clark, J. answered the question in the affirmative, at p. 486:
"The privilege afforded not only extends to answers that
would in themselves support a conviction under a federal
criminal statute but likewise embraces those which
would furnish a link in the chain of evidence needed to
prosecute the claimant for a federal crime. [...]
But this protection must be confined to instances where
the witness has reasonable cause to apprehend danger
from a direct answer. [...]"
(internal citations omitted)
"To sustain the privilege, it need only be evident from the
implications of the question, in the setting in which it is
asked, that a responsive answer to the question or an
127
explanation of why it cannot be answered might be
dangerous because injurious disclosure may result."
(at p. 487)
117. However, Krishna Iyer, J. also cautioned against
including in the prohibition even those answers which might
be used as a step towards obtaining evidence against the
accused. It was stated, (1978) 2 SCC 424, at p. 451:
"The policy behind the privilege, under our scheme, does
not swing so wide as to sweep out of admissibility
statements neither confessional per se nor guilty in
tendency but merely relevant facts which, viewed in any
setting, does not have a sinister import. To spread the
net so wide is to make a mockery of the examination of
the suspect, so necessitous in the search for truth.
Overbreadth undermines, and we demur to such morbid
exaggeration of a wholesome protection. ...
In Kathi Kalu Oghad's case, this Court authoritatively
observed, on the bounds between constitutional
proscription and testimonial permission:
`In order that a testimony by an accused person
may be said to have been self-incriminatory, the
compulsion of which comes within the prohibition of
the constitutional provisions, it must be of such a
character that by itself it should have the tendency
of incriminating the accused, if not also of actually
doing so. In other words, it should be a statement
which makes the case against the accused at least
probable, considered by itself.' [1962] 3 SCR 10, 32
Again the Court indicated that Article 20(3) could be
invoked only against statements which `had a material
bearing on the criminality of the maker of the statement'.
128
`By itself' does not exclude the setting or other integral
circumstances but means something in the fact disclosed
a guilt element. Blood on clothes, gold bars with
notorious marks and presence on the scene or
possession of the lethal weapon or corrupt currency have
a tale to tell, beyond red fluid, precious metal, gazing at
the stars or testing sharpness or value of the rupee. The
setting of the case is an implied component of the
statement."
118. In light of these observations, we must examine the
permissibility of extracting statements which may furnish a
link in the chain of evidence and hence create a risk of
exposure to criminal charges. The crucial question is whether
such derivative use of information extracted in a custodial
environment is compatible with Article 20(3). It is a settled
principle that statements made in custody are considered to
be unreliable unless they have been subjected to cross-
examination or judicial scrutiny. The scheme created by the
Code of Criminal Procedure and the Indian Evidence Act also
mandates that confessions made before police officers are
ordinarily not admissible as evidence and it is only the
statements made in the presence of a judicial magistrate
which can be given weightage. The doctrine of excluding the
129
`fruits of a poisonous tree' has been incorporated in Sections
24, 25 and 26 of the Indian Evidence Act, 1872 which read as
follows:
24. Confession caused by inducement, threat or
promise, when irrelevant in criminal proceeding. - A
confession made by an accused person is irrelevant in a
criminal proceeding, if the making of the confession
appears to the Court to have been caused by any
inducement, threat or promise, having reference to the
charge against the accused person, proceeding from a
person in authority and sufficient, in the opinion of the
Court, to give the accused person grounds, which would
appear to him reasonable, for supposing that by making
it he would gain any advantage or avoid any evil of a
temporal nature in reference to the proceedings against
him.
25. Confession to police officer not proved. - No
confession made to a police officer shall be proved as
against a person accused of any offence.
26. Confession by accused while in custody of police
not to be proved against him. - No confession made by
any person whilst he is in the custody of a police officer,
unless it be made in the immediate presence of a
Magistrate, shall be proved as against such person.
119. We have already referred to the language of Section 161,
CrPC which protects the accused as well as suspects and
witnesses who are examined during the course of investigation
in a criminal case. It would also be useful to refer to Sections
130
162, 163 and 164 of the CrPC which lay down procedural
safeguards in respect of statements made by persons during
the course of investigation. However, Section 27 of the
Evidence Act incorporates the `theory of confirmation by
subsequent facts' - i.e. statements made in custody are
admissible to the extent that they can be proved by the
subsequent discovery of facts. It is quite possible that the
content of the custodial statements could directly lead to the
subsequent discovery of relevant facts rather than their
discovery through independent means. Hence such statements
could also be described as those which `furnish a link in the
chain of evidence' needed for a successful prosecution. This
provision reads as follows:
27. How much of information received from accused
may be proved. - Provided that, when any fact is
deposed to as discovered in consequence of information
received from a person accused of any offence, in the
custody of a police officer, so much of such information,
whether it amounts to a confession or not, as relates
distinctly to the fact thereby discovered, may be proved.
120. This provision permits the derivative use of custodial
statements in the ordinary course of events. In Indian law,
131
there is no automatic presumption that the custodial
statements have been extracted through compulsion. In short,
there is no requirement of additional diligence akin to the
administration of Miranda warnings. However, in
circumstances where it is shown that a person was indeed
compelled to make statements while in custody, relying on
such testimony as well as its derivative use will offend Article
20(3). The relationship between Section 27 of the Evidence Act
and Article 20(3) of the Constitution was clarified in Kathi
Kalu Oghad (supra.). It was observed in the majority opinion
by Jagannadhadas, J., at pp. 33-34:
"The information given by an accused person to a police
officer leading to the discovery of a fact which may or
may not prove incriminatory has been made admissible
in evidence by that Section. If it is not incriminatory of
the person giving the information, the question does not
arise. It can arise only when it is of an incriminatory
character so far as the giver of the information is
concerned. If the self-incriminatory information has been
given by an accused person without any threat, that will
be admissible in evidence and that will not be hit by the
provisions of cl. (3) of Art. 20 of the Constitution for the
reason that there has been no compulsion. It must,
therefore, be held that the provisions of s. 27 of the
Evidence Act are not within the prohibition aforesaid,
unless compulsion has been used in obtaining the
information."
(emphasis supplied)
132
This position was made amply clear at pp. 35-36:
"Hence, the mere fact that the accused person, when he
made the statement in question was in police custody
would not, by itself, be the foundation for an inference of
law that the accused was compelled to make the
statement. Of course, it is open to an accused person to
show that while he was in police custody at the relevant
time, he was subjected to treatment which, in the
circumstances of the case, would lend itself to the
inference that compulsion was, in fact, exercised. In
other words, it will be a question of fact in each case to
be determined by the Court on weighing the facts and
circumstances disclosed in the evidence before it."
121. The minority opinion also agreed with the majority's
conclusion on this point since Das Gupta, J., held at p. 47:
"Section 27 provides that when any fact is deposed to as
discovered in consequence of information received from a
person accused of any offence, in the custody of a police
officer, so much of the information, whether it amounts
to a confession or not, as relates distinctly to the fact
thereby discovered, may be proved. It cannot be disputed
that by giving such information the accused furnishes
evidence, and therefore is a `witness' during the
investigation. Unless, however he is `compelled' to give
the information he cannot be said to be `compelled' to be
a witness; and so Article 20(3) is not infringed.
Compulsion is not however inherent in the receipt of
information from an accused person in the custody of a
police officer. There may be cases where an accused in
custody is compelled to give the information later on
sought to be proved under s. 27. There will be other
cases where the accused gives the information without
any compulsion. Where the accused is compelled to give
133
information it will be an infringement of Art. 20(3); but
there is no such infringement where he gives the
information without any compulsion. ..."
122. We must also address another line of reasoning which
was adopted in one of the impugned judgments. It was stated
that the exclusionary rule in evidence law is applicable to
statements that are inculpatory in nature. Based on this
premise, it was observed that at the time of administering the
impugned tests, it cannot be ascertained whether the resulting
revelations or inferences will prove to be inculpatory or
exculpatory in due course. Taking this reasoning forward, it
was held that the compulsory administration of the impugned
tests should be permissible since the same does not
necessarily lead to the extraction of inculpatory evidence. We
are unable to agree with this reasoning.
123. The distinction between inculpatory and exculpatory
evidence gathered during investigation is relevant for deciding
what will be admissible as evidence during the trial stage. The
exclusionary rule in evidence law mandates that if inculpatory
134
evidence has been gathered through improper methods
(involving coercion, threat or inducement among others) then
the same should be excluded from the trial, while there is no
such prohibition on the consideration of exculpatory evidence.
However, this distinction between the treatment of inculpatory
and exculpatory evidence is made retrospectively at the trial
stage and it cannot be extended back to the stage of
investigation. If we were to permit the admission of involuntary
statement on the ground that at the time of asking a question
it is not known whether the answer will be inculpatory or
exculpatory, the `right against self-incrimination' will be
rendered meaningless. The law confers on `any person' who is
examined during an investigation, an effective choice between
speaking and remaining silent. This implies that it is for the
person being examined to decide whether the answer to a
particular question will eventually prove to be inculpatory or
exculpatory. Furthermore, it is also likely that the information
or materials collected at an earlier stage of investigation can
prove to be inculpatory in due course.
135
124. However, it is conceivable that in some circumstances the
testimony extracted through compulsion may not actually lead
to exposure to criminal charges or penalties. For example this
is a possibility when the investigators make an offer of
immunity against the direct use, derivative use or
transactional use of the testimony. Immunity against direct
use entails that a witness will not be prosecuted on the basis
of the statements made to the investigators. A protection
against derivative use implies that a person will not be
prosecuted on the basis of the fruits of such testimony.
Immunity against transactional use will shield a witness from
criminal charges in cases other than the one being
investigated. It is of course entirely up to the investigating
agencies to decide whether to offer immunity and in what
form. Even though this is distinctly possible, it is difficult to
conceive of such a situation in the context of the present case.
A person who is given an offer of immunity against
prosecution is far more likely to voluntarily cooperate with the
investigation efforts. This could be in the form of giving
testimony or helping in the discovery of material evidence. If a
136
person is freely willing to cooperate with the investigation
efforts, it would be redundant to compel such a person to
undergo the impugned tests. If reliance on such tests is
sought for refreshing a cooperating witness' memory, the
person will in all probability give his/her consent to undergo
these tests.
125. It could be argued that the compulsory administration of
the impugned tests can prove to be useful in instances where
the cooperating witness has difficulty in remembering the
relevant facts or is wilfully concealing crucial details. Such
situations could very well arise when a person who is a co-
accused is offered immunity from prosecution in return for
cooperating with the investigators. Even though the right
against self-incrimination is not directly applicable in such
situations, the relevant legal inquiry is whether the
compulsory administration of the impugned tests meets the
requisite standard of `substantive due process' for placing
restraints on personal liberty.
137
126. At this juncture, it must be reiterated that Indian law
incorporates the `rule against adverse inferences from silence'
which is operative at the trial stage. As mentioned earlier, this
position is embodied in a conjunctive reading of Article 20(3) of
the Constitution and Sections 161(2), 313(3) and Proviso (b) of
Section 315(1) of the CrPC. The gist of this position is that
even though an accused is a competent witness in his/her
own trial, he/she cannot be compelled to answer questions
that could expose him/her to incrimination and the trial judge
cannot draw adverse inferences from the refusal to do so. This
position is cemented by prohibiting any of the parties from
commenting on the failure of the accused to give evidence.
This rule was lucidly explained in the English case of
Woolmington v. DPP, (1935) AC 462, at p. 481:
"The `right to silence' is a principle of common law and it
means that normally courts or tribunals of fact should
not be invited or encouraged to conclude, by parties or
prosecutors, that a suspect or an accused is guilty
merely because he has refused to respond to questions
put to him by the police or by the Court."
127. The 180th Report of the Law Commission of India (May
2002) dealt with this very issue. It considered arguments for
138
diluting the `rule against adverse inferences from silence'.
Apart from surveying several foreign statutes and decisions,
the report took note of the fact that Section 342(2) of the
erstwhile Code of Criminal Procedure, 1898 permitted the trial
judge to draw an inference from the silence of the accused.
However, this position was changed with the enactment of the
new Code of Criminal Procedure in 1973, thereby prohibiting
the making of comments as well as the drawing of inferences
from the fact of an accused's silence. In light of this, the report
concluded:
"... We have reviewed the law in other countries as well
as in India for the purpose of examining whether any
amendments are necessary in the Code of Criminal
Procedure, 1973. On a review, we find that no changes in
the law relating to silence of the accused are necessary
and if made, they will be ultra vires of Article 20(3) and
Article 21 of the Constitution of India. We recommend
accordingly."
128. Some commentators have argued that the `rule against
adverse inferences from silence' should be broadly construed
in order to give protection against non-penal consequences. It
is reasoned that the fact of a person's refusal to answer
questions should not be held against him/her in a wide variety
139
of settings, including those outside the context of criminal
trials. A hypothetical illustration of such a setting is a
deportation hearing where an illegal immigrant could be
deported following a refusal to answer questions or furnish
materials required by the concerned authorities. This question
is relevant for the present case because a person who refuses
to undergo the impugned tests during the investigative stage
could face non-penal consequences which lie outside the
protective scope of Article 20(3). For example, a person who
refuses to undergo these tests could face the risk of custodial
violence, increased police surveillance or harassment
thereafter. Even a person who is compelled to undergo these
tests could face such adverse consequences on account of the
contents of the test results if they heighten the investigators'
suspicions. Each of these consequences, though condemnable,
fall short of the requisite standard of `exposure to criminal
charges and penalties' that has been enumerated in Section
161(2) of the CrPC. Even though Article 20(3) will not be
applicable in such circumstances, reliance can be placed on
Article 21 if such non-penal consequences amount to a
140
violation of `personal liberty' as contemplated under the
Constitution. In the past, this Court has recognised the rights
of prisoners (undertrials as well as convicts) as well as
individuals in other custodial environments to receive `fair,
just and equitable' treatment. For instance in Sunil Batra v.
Delhi Administration, (1978) 4 SCC 494, it was decided that
practices such as `solitary confinement' and the use of bar-
fetters in jails were violative of Article 21. Hence, in
circumstances where persons who refuse to answer questions
during the investigative stage are exposed to adverse
consequences of a non-penal nature, the inquiry should
account for the expansive scope of Article 21 rather than the
right contemplated by Article 20(3).
I-B. Whether the results derived from the impugned
techniques amount to `testimonial compulsion' thereby
attracting the bar of Article 20(3)?
129. The next issue is whether the results gathered from the
impugned tests amount to `testimonial compulsion', thereby
141
attracting the prohibition of Article 20(3). For this purpose, it
is necessary to survey the precedents which deal with what
constitutes `testimonial compulsion' and how testimonial acts
are distinguished from the collection of physical evidence.
Apart from the apparent distinction between evidence of a
testimonial and physical nature, some forms of testimonial
acts lie outside the scope of Article 20(3). For instance, even
though acts such as compulsorily obtaining specimen
signatures and handwriting samples are testimonial in nature,
they are not incriminating by themselves if they are used for
the purpose of identification or corroboration with facts or
materials that the investigators are already acquainted with.
The relevant consideration for extending the protection of
Article 20(3) is whether the materials are likely to lead to
incrimination by themselves or `furnish a link in the chain of
evidence' which could lead to the same result. Hence, reliance
on the contents of compelled testimony comes within the
prohibition of Article 20(3) but its use for the purpose of
identification or corroboration with facts already known to the
investigators is not barred.
142
130. It is quite evident that the narcoanalysis technique
involves a testimonial act. A subject is encouraged to speak in
a drug-induced state, and there is no reason why such an act
should be treated any differently from verbal answers during
an ordinary interrogation. In one of the impugned judgments,
the compulsory administration of the narcoanalysis technique
was defended on the ground that at the time of conducting the
test, it is not known whether the results will eventually prove
to be inculpatory or exculpatory. We have already rejected this
reasoning. We see no other obstruction to the proposition that
the compulsory administration of the narcoanalysis technique
amounts to `testimonial compulsion' and thereby triggers the
protection of Article 20(3).
131. However, an unresolved question is whether the results
obtained through polygraph examination and the BEAP test
are of a testimonial nature. In both these tests, inferences are
drawn from the physiological responses of the subject and no
direct reliance is placed on verbal responses. In some forms of
143
polygraph examination, the subject may be required to offer
verbal answers such as `Yes' or `No', but the results are based
on the measurement of changes in several physiological
characteristics rather than these verbal responses. In the
BEAP test, the subject is not required to give any verbal
responses at all and inferences are drawn from the
measurement of electrical activity in the brain. In the
impugned judgments, it has been held that the results
obtained from both the Polygraph examination and the BEAP
test do not amount to `testimony' thereby lying outside the
protective scope of Article 20(3). The same assertion has been
reiterated before us by the counsel for the respondents. In
order to evaluate this position, we must examine the contours
of the expression `testimonial compulsion'.
132. The question of what constitutes `testimonial compulsion'
for the purpose of Article 20(3) was addressed in M.P.
Sharma's case (supra.). In that case, the Court considered
whether the issuance of search warrants in the course of an
investigation into the affairs of a company (following
144
allegations of misappropriation and embezzlement) amounted
to an infringement of Article 20(3). The search warrants issued
under Section 96 of the erstwhile Code of Criminal Procedure,
1898 authorised the investigating agencies to search the
premises and seize the documents maintained by the said
company. The relevant observations were made by
Jagannadhadas, J., at pp. 1087-1088:
" ... The phrase used in Article 20(3) is `to be a witness'. A
person can `be a witness' not merely by giving oral
evidence but also by producing documents or making
intelligible gestures as in the case of a dumb witness [see
Section 119 of the Evidence Act or the like]. `To be a
witness' is nothing more than `to furnish evidence', and
such evidence can be furnished through the lips or by
production of a thing or of a document or in other modes.
...
Indeed, every positive volitional act which furnishes
evidence is testimony, and testimonial compulsion
connotes coercion which procures the positive volitional
evidentiary acts of the person, as opposed to the negative
attitude of silence or submission on his part. ..."
133. These observations suggest that the phrase `to be a
witness' is not confined to oral testimony for the purpose of
invoking Article 20(3) and that it includes certain non-verbal
forms of conduct such as the production of documents and
145
the making of intelligible gestures. However, in Kathi Kalu
Oghad (supra.), there was a disagreement between the
majority and minority opinions on whether the expression `to
be a witness' was the same as `to furnish evidence'. In that
case, this Court had examined whether certain statutory
provisions, namely - Section 73 of the Evidence Act, Sections 5
and 6 of the Identification of Prisoners Act, 1920 and Section
27 of the Evidence Act were compatible with Article 20(3).
Section 73 of the Evidence Act empowered courts to obtain
specimen handwriting or signatures and finger impressions of
an accused person for purposes of comparison. Sections 5 and
6 of the Identification of Prisoners Act empowered a Magistrate
to obtain the photograph or measurements of an accused
person. In respect of Section 27 of the Evidence Act, there was
an agreement between the majority and the minority opinions
that the use of compulsion to extract custodial statements
amounts to an exception to the `theory of confirmation by
subsequent facts'. We have already referred to the relevant
observations in an earlier part of this opinion. Both the
majority and minority opinions ruled that the other statutory
146
provisions mentioned above were compatible with Article 20(3),
but adopted different approaches to arrive at this conclusion.
In the majority opinion it was held that the ambit of the
expression `to be a witness' was narrower than that of
`furnishing evidence'. B.P. Sinha, C.J. observed, [1962] 3 SCR
10, at pp. 29-32:
" `To be a witness' may be equivalent to `furnishing
evidence' in the sense of making oral or written
statements, but not in the larger sense of the expression
so as to include giving of thumb impression or
impression of palm or foot or fingers or specimen writing
or exposing a part of the body by an accused person for
purpose of identification. `Furnishing evidence' in the
latter sense could not have been within the
contemplation of the Constitution-makers for the simple
reason that - though they may have intended to protect
an accused person from the hazards of self-
incrimination, in the light of the English Law on the
subject - they could not have intended to put obstacles in
the way of efficient and effective investigation into crime
and of bringing criminals to justice. The taking of
impressions or parts of the body of an accused person
very often becomes necessary to help the investigation of
a crime. It is as much necessary to protect an accused
person against being compelled to incriminate himself, as
to arm the agents of law and the law courts with
legitimate powers to bring offenders to justice.
Furthermore it must be assumed that the Constitution-
makers were aware of the existing law, for example,
Section 73 of the Evidence Act or Section 5 and 6 of the
Identification of Prisoners Act (XXXIII of 1920).
147
... The giving of finger impression or of specimen
signature or of handwriting, strictly speaking, is not `to
be a witness'. `To be a witness' means imparting
knowledge in respect of relevant fact, by means of oral
statements or statements in writing, by a person who has
personal knowledge of the facts to be communicated to a
court or to a person holding an enquiry or investigation.
A person is said `to be a witness' to a certain state of facts
which has to be determined by a court or authority
authorised to come to a decision, by testifying to what he
has seen, or something he has heard which is capable of
being heard and is not hit by the rule excluding hearsay
or giving his opinion, as an expert, in respect of matters
in controversy. Evidence has been classified by text
writers into three categories, namely, (1) oral testimony;
(2) evidence furnished by documents; and (3) material
evidence. We have already indicated that we are in
agreement with the Full Court decision in Sharma's case,
[1954] SCR 1077, that the prohibition in cl. (3) of Art. 20
covers not only oral testimony given by a person accused
of an offence but also his written statements which may
have a bearing on the controversy with reference to the
charge against him. ...
... Self-incrimination must mean conveying information
based upon the personal knowledge of the person giving
the information and cannot include merely the
mechanical process of producing documents in court
which may throw a light on any of the points in
controversy, but which do not contain any statement of
the accused based on his personal knowledge. For
example, the accused person may be in possession of a
document which is in his writing or which contains his
signature or his thumb impression. The production of
such a document, with a view to comparison of the
writing or the signature or the impression, is not the
statement of an accused person, which can be said to be
of the nature of a personal testimony. When an accused
person is called upon by the Court or any other authority
148
holding an investigation to give his finger impression or
signature or a specimen of his handwriting, he is not
giving any testimony of the nature of a `personal
testimony'. The giving of a `personal testimony' must
depend on his volition. He can make any kind of
statement or may refuse to make any statement. But his
finger impressions or his handwriting, in spite of efforts
at concealing the true nature of it by dissimulation
cannot change their intrinsic character. Thus, the giving
of finger impressions or of specimen writing or of
signatures by an accused person, though it may amount
to `furnishing evidence' in the larger sense, is not
included within the expression `to be a witness'.
In order that a testimony by an accused person may be
said to have been self-incriminatory, the compulsion of
which comes within the prohibition of the constitutional
provision, it must be of such a character that by itself it
should have the tendency of incriminating the accused, if
not also of actually doing so. In other words, it should be
a statement which makes the case against the accused
person atleast probable, considered by itself. A specimen
handwriting or signature or finger impressions by
themselves are no testimony at all, being wholly
innocuous because they are unchangeable except in rare
cases where the ridges of the fingers or the style of
writing have been tampered with. They are only materials
for comparison in order to lend assurance to the Court
that its inference based on other pieces of evidence is
reliable. They are neither oral nor documentary evidence
but belong to the third category of material evidence
which is outside the limit of `testimony'."
134. Hence, B.P. Sinha, C.J. construed the expression `to be a
witness' as one that was limited to oral or documentary
evidence, while further confining the same to statements that
149
could lead to incrimination by themselves, as opposed to those
used for the purpose of identification or comparison with facts
already known to the investigators. The minority opinion
authored by Das Gupta, J. (3 judges) took a different
approach, which is evident from the following extracts, Id. at
pp. 40-43:
"That brings us to the suggestion that the expression `to
be a witness' must be limited to a statement whether oral
or in writing by an accused person imparting knowledge
of relevant facts; but that mere production of some
material evidence, whether documentary or otherwise
would not come within the ambit of this expression. This
suggestion has found favour with the majority of the
Bench, we think however that this is an unduly narrow
interpretation. We have to remind ourselves that while on
the one hand we should bear in mind that the
Constitution-makers could not have intended to stifle
legitimate modes of investigation we have to remember
further that quite clearly they thought that certain things
should not be allowed to be done, during the
investigation, or trial, however helpful they might seem to
be to the unfolding of truth and an unnecessary
apprehension of disaster to the police system and the
administration of justice, should not deter us from giving
the words their proper meaning. It appears to us that to
limit the meaning of the words `to be a witness' in Art.
20(3) in the manner suggested would result in allowing
compulsion to be used in procuring the production from
the accused of a large number of documents, which are
of evidentiary value, sometimes even more so than any
oral statement of a witness might be. ...
150
... There can be no doubt that to the ordinary user of
English words, the word `witness' is always associated
with evidence, so that to say that `to be a witness' is to
`furnish evidence' is really to keep to the natural meaning
of the words. ...
... It is clear from the scheme of the various provisions,
dealing with the matter that the governing idea is that to
be evidence, the oral statement or a statement contained
in a document, shall have a tendency to prove a fact -
whether it be a fact in issue or a relevant fact - which is
sought to be proved. Though this definition of evidence is
in respect of proceedings in Court it will be proper, once
we have come to the conclusion, that the protection of
Art. 20(3) is available even at the stage of investigation, to
hold that at that stage also the purpose of having a
witness is to obtain evidence and the purpose of evidence
is to prove a fact.
The illustrations we have given above show clearly that it
is not only by imparting of his knowledge that an accused
person assists the proving of a fact; he can do so even by
other means, such as the production of documents which
though not containing his own knowledge would have a
tendency to make probable the existence of a fact in
issue or a relevant fact."
135. Even though Das Gupta, J. saw no difference between
the scope of the expressions `to be a witness' and `to furnish
evidence', the learned judge agreed with the majority's
conclusion that for the purpose of invoking Article 20(3) the
evidence must be incriminating by itself. This entailed that
evidence could be relied upon if it is used only for the purpose
151
of identification or comparison with information and materials
that are already in the possession of the investigators. The
following observations were made at pp. 45-46:
" ... But the evidence of specimen handwriting or the
impressions of the accused person's fingers, palm or foot,
will incriminate him, only if on comparison of these with
certain other handwritings or certain other impressions,
identity between the two sets is established. By
themselves, these impressions or the handwritings do not
incriminate the accused person, or even tend to do so.
That is why it must be held that by giving these
impressions or specimen handwriting, the accused
person does not furnish evidence against himself. ...
... This view, it may be pointed out does not in any way
militate against the policy underlying the rule against
`testimonial compulsion' we have already discussed
above. There is little risk, if at all, in the investigator or
the prosecutor being induced to lethargy or inaction
because he can get such handwriting or impressions
from an accused person. For, by themselves they are of
little or of no assistance to bring home the guilt of an
accused. Nor is there any chance of the accused to
mislead the investigator into wrong channels by
furnishing false evidence. For, it is beyond his power to
alter the ridges or other characteristics of his hand, palm
or finger or to alter the characteristics of his handwriting.
We agree therefore with the conclusion reached by the
majority of the Bench that there is no infringement of Art.
20(3) of the Constitution by compelling an accused
person to give his specimen handwriting or signature; or
impressions of his fingers, palm or foot to the
investigating officer or under orders of a court for the
purpose of comparison under the provisions of s. 73 of
the Indian Evidence Act; though we have not been able to
152
agree with the view of our learned brethren that `to be a
witness' in Art. 20(3) should be equated with the
imparting of personal knowledge or that an accused does
not become a witness when he produces some document
not in his own handwriting even though it may tend to
prove facts in issue or relevant facts against him."
136. Since the majority decision in Kathi Kalu Oghad
(supra.) is the controlling precedent, it will be useful to re-
state the two main premises for understanding the scope of
`testimonial compulsion'. The first is that ordinarily it is the
oral or written statements which convey the personal
knowledge of a person in respect of relevant facts that amount
to `personal testimony' thereby coming within the prohibition
contemplated by Article 20(3). In most cases, such `personal
testimony' can be readily distinguished from material evidence
such as bodily substances and other physical objects. The
second premise is that in some cases, oral or written
statements can be relied upon but only for the purpose of
identification or comparison with facts and materials that are
already in the possession of the investigators. The bar of
Article 20(3) can be invoked when the statements are likely to
lead to incrimination by themselves or `furnish a link in the
153
chain of evidence' needed to do so. We must emphasize that a
situation where a testimonial response is used for comparison
with facts already known to investigators is inherently
different from a situation where a testimonial response helps
the investigators to subsequently discover fresh facts or
materials that could be relevant to the ongoing investigation.
137. The recognition of the distinction between testimonial
acts and physical evidence for the purpose of invoking Article
20(3) of the Constitution finds a close parallel in some foreign
decisions. In Armando Schmerber v. California, 384 US 757
(1966), the U.S. Supreme Court had to determine whether an
involuntary blood test of a defendant had violated the Fifth
Amendment. The defendant was undergoing treatment at a
hospital following an automobile accident. A blood sample was
taken against his will at the direction of a police officer.
Analysis of the same revealed that Schmerber had been
intoxicated and these results were admitted into evidence,
thereby leading to his conviction for drunk driving. An
objection was raised on the basis of the Fifth Amendment and
154
the majority opinion (Brennan, J.) relied on a distinction
between evidence of a `testimonial' or `communicative' nature
as opposed to evidence of a `physical' or `real nature',
concluding that the privilege against self-incrimination applied
to the former but not to the latter. In arriving at this decision,
reference was made to several precedents with a prominent
one being United States v. Holt, 218 US 245 (1910). In that
case, a defendant was forced to try on an article of clothing
during the course of investigation. It had been ruled that the
privilege against self-incrimination prohibited the use of
compulsion to `extort communications' from the defendant,
but not the use of the defendant's body as evidence.
138. In addition to citing John Wigmore's position that `the
privilege is limited to testimonial disclosures' the Court in
Schmerber also took note of other examples where it had been
held that the privilege did not apply to physical evidence,
which included `compulsion to submit to fingerprinting,
photographing, or measurements, to write or speak for
identification, to appear in court, to stand, to assume a
155
stance, to walk, or to make a particular gesture.' However, it
was cautioned that the privilege applied to testimonial
communications, irrespective of what form they might take.
Hence it was recognised that the privilege not only extended to
verbal communications, but also to written words as well as
gestures intended to communicate [for, e.g., pointing or
nodding]. This line of thinking becomes clear because the
majority opinion indicated that the distinction between
testimonial and physical acts may not be readily applicable in
the case of Lie-Detector tests. Brennan, J. had noted, 384 US
757 (1966), at p. 764:
"Although we agree that this distinction is a helpful
framework for analysis, we are not to be understood to
agree with past applications in all instances. There will
be many cases in which such a distinction is not readily
drawn. Some tests seemingly directed to obtain `physical
evidence,' for example, lie detector tests measuring
changes in body function during interrogation, may
actually be directed to eliciting responses which are
essentially testimonial. To compel a person to submit to
testing in which an effort will be made to determine his
guilt or innocence on the basis of physiological
responses, whether willed or not, is to evoke the spirit
and history of the Fifth Amendment. Such situations call
to mind the principle that the protection of the privilege
`is as broad as the mischief against which it seeks to
guard.' [...]"
156
In a recently published paper, Michael S. Pardo (2008) has
made the following observation in respect of this judgment
[Cited from: Michael S. Pardo, `Self-Incrimination and the
Epistemology of Testimony', 30 Cardozo Law Review 1023-
1046 (December 2008) at pp. 1027-1028]:
"the Court notes that even the physical-testimonial
distinction may break down when physical evidence is
meant to compel `responses which are essentially
testimonial' such as a lie-detector test measuring
physiological responses during interrogation."
139. Following the Schmerber decision (supra.), the
distinction between physical and testimonial evidence has
been applied in several cases. However, some complexities
have also arisen in the application of the testimonial-physical
distinction to various fact-situations. While we do not need to
discuss these cases to decide the question before us, we must
take note of the fact that the application of the testimonial-
physical distinction can be highly ambiguous in relation to
non-verbal forms of conduct which nevertheless convey
relevant information. Among other jurisdictions, the European
Court of Human Rights (ECtHR) has also taken note of the
distinction between testimonial and physical acts for the
157
purpose of invoking the privilege against self-incrimination. In
Saunders v. United Kingdom, (1997) 23 EHRR 313, it was
explained:
"... The right not to incriminate oneself, in particular,
presupposes that the prosecution in a criminal case seek
to prove their case against the accused without resort to
evidence obtained through methods of coercion or
oppression in defiance of the will of the accused. In this
sense the right is closely linked to the presumption of
innocence ... The right not to incriminate oneself is
primarily concerned, however, with respecting the will of
an accused person to remain silent. As commonly
understood in the legal systems of the Contracting
Parties to the Convention and elsewhere, it does not
extend to the use in criminal proceedings of material
which may be obtained from the accused through the use
of compulsory powers but which has an existence
independent of the will of the suspect such as, inter alia,
documents acquired pursuant to a warrant, breath,
blood and urine samples and bodily tissue for the
purpose of DNA testing."
Evolution of the law on `medical examination'
140. With respect to the testimonial-physical distinction, an
important statutory development in our legal system was the
introduction of provisions for medical examination with the
overhauling of the Code of Criminal Procedure in 1973.
Sections 53 and 54 of the CrPC contemplate the medical
examination of a person who has been arrested, either at the
158
instance of the investigating officer or even the arrested person
himself. The same can also be done at the direction of the
jurisdictional court.
141. However, there were no provisions for authorising such a
medical examination in the erstwhile Code of Criminal
Procedure, 1898. The absence of a statutory basis for the
same had led courts to hold that a medical examination could
not be conducted without the prior consent of the person who
was to be subjected to the same. For example in Bhondar v.
Emperor, AIR 1931 Cal 601, Lord Williams, J. held, at p. 602:
"If it were permitted forcibly to take hold of a prisoner
and examine his body medically for the purpose of
qualifying some medical witness to give medical evidence
in the case against the accused there is no knowing
where such procedure would stop.
...Any such examination without the consent of the
accused would amount to an assault and I am quite
satisfied that the police are not entitled without statutory
authority to commit assaults upon prisoners for the
purpose of procuring evidence against them. If the
legislature desires that evidence of this kind should be
given, it will be quite simple to add a short section to the
Code of Criminal Procedure expressly giving power to
order such a medical examination."
159
S.K. Ghose, J. concurred, at p. 604:
"Nevertheless the examination of an arrested person in
hospital by a doctor, not for the benefit of the prisoner's
health, but simply by way of a second search, is not
provided for by Code, and is such a case the doctor may
not examine the prisoner without his consent. It would
be a rule of caution to have such consent noted in the
medical report, so that the doctor would be in a position
to testify to such consent if called upon to do so."
A similar conclusion was arrived at by Tarkunde, J. in
Deomam Shamji Patel v. State of Maharashtra, AIR 1959
Bom 284, who held that a person suspected or accused of
having committed an offence cannot be forcibly subjected to a
medical examination. It was also held that if police officers use
force for this purpose, then a person can lawfully exercise the
right of private defence to offer resistance.
142. It was the 37th and 41st Reports of the Law Commission of
India which recommended the insertion of a provision in the
Code of Criminal Procedure to enable medical examination
without the consent of an accused. These recommendations
proved to be the precursor for the inclusion of Sections 53 and
54 in the Code of Criminal Procedure, 1973. It was observed in
the 37th Report (December 1967), at pp. 205-206:
" ... It will suffice to refer to the decision of the Supreme
Court in Kathi Kalu, [AIR 1961 SC 1808] which has the
160
effect of confining the privilege under Article 20(3) to
testimony - written or oral. [Fn ...] The Supreme Court's
judgment in Kathi Kalu should be taken as overruling the
view taken in some earlier decisions, [Fn 6, 7 ...]
invalidating provisions similar to Section 5, Identification
of Prisoners Act, 1920.
The position in the U.S.A. has been summarised [Fn 8 -
Emerson G., `Due Process and the American Criminal
Trial', 33 Australian Law Journal 223, 231 (1964)]
`Less certain is the protection accorded to the
defendant with regard to non-testimonial physical
evidence other than personal papers. Can the
accused be forced to supply a sample of his blood or
urine if the resultant tests are likely to further the
prosecution's case? Can he be forced to give his
finger prints to wear a disguise or certain clothing,
to supply a pair of shoes which might match
footprints at the scene of the crime, to stand in a
line-up, to submit to a hair cut or to having his hair
dyed, or to have his stomach pumped or a
fluoroscopic examination of the contents of his
intestines? The literature on this aspect of self-
incrimination is voluminous. [Fn ...]
The short and reasonably accurate answer to the
question posed is that almost all such physical acts can
be required. [Fn ...] Influenced by the historical
development of the doctrine, its purpose, and the need to
balance the conflicting interests of the individual and
society, the courts have generally restricted the
protection of the Fifth Amendment to situations where
the defendant would be required to convey ideas, or
where the physical acts would offend the decencies of
civilized conduct."
(some internal citations omitted)
161
Taking note of Kathi Kalu Oghad (supra.) and the distinction
drawn between testimonial and physical acts in American
cases, the Law Commission observed that a provision for
examination of the body would reveal valuable evidence. This
view was taken forward in the 41st Report which recommended
the inclusion of a specific provision to enable medical
examination during the course of investigation, irrespective of
the subject's consent. [See: 41st Report of the Law Commission
of India, Vol. I (September 1969), Para 5.1 at p. 37]
143. We were also alerted to some High Court decisions which
have relied on Kathi Kalu Oghad (supra.) to approve the
taking of physical evidence such as blood and hair samples in
the course of investigation. Following the overhaul of the Code
of Criminal Procedure in 1973, the position became amply
clear. In recent years, the judicial power to order a medical
examination, albeit in a different context, has been discussed
by this Court in Sharda v. Dharampal, (2003) 4 SCC 493. In
that case, the contention related to the validity of a civil
court's direction for conducting a medical examination to
162
ascertain the mental state of a party in a divorce proceeding.
Needless to say, the mental state of a party was a relevant
issue before the trial court, since insanity is a statutory
ground for obtaining divorce under the Hindu Marriage Act,
1955. S.B. Sinha, J. held that Article 20(3) was anyway not
applicable in a civil proceeding and that the civil court could
direct the medical examination in exercise of its inherent
powers under Section 151 of the Code of Civil Procedure, since
there was no ordinary statutory basis for the same. It was
observed, Id. at p. 508:
"Yet again the primary duty of a court is to see that truth
is arrived at. A party to a civil litigation, it is axiomatic, is
not entitled to constitutional protections under Article 20
of the Constitution of India. Thus, the civil court
although may not have any specific provisions in the
Code of Civil Procedure and the Evidence Act, has an
inherent power in terms of Section 151 of the Code of
Civil Procedure to pass all orders for doing complete
justice to the parties to the suit.
Discretionary power under Section 151 of the Code of
Civil Procedure, it is trite, can be exercised also on an
application filed by the party. In certain cases medical
examination by the experts in the field may not only be
found to be leading to the truth of the matter but may
also lead to removal of misunderstanding between the
parties. It may bring the parties to terms. Having regard
to development in medicinal technology, it is possible to
find out that what was presumed to be a mental disorder
163
of a spouse is not really so. In matrimonial disputes, the
court also has a conciliatory role to play - even for the
said purpose it may require expert advice.
Under Section 75(e) of the Code of Civil Procedure and
Order 26, Rule 10-A the civil court has the requisite
power to issue a direction to hold a scientific, technical or
expert investigation."
144. The decision had also cited some foreign precedents
dealing with the authority of investigators and courts to
require the collection of DNA samples for the purpose of
comparison. In that case the discussion centered on the `right
to privacy'. So far, the authority of investigators and courts to
compel the production of DNA samples has been approved by
the Orissa High Court in Thogorani v. State of Orissa, 2004
Cri L J 4003 (Ori).
145. At this juncture, it should be noted that the Explanation
to Sections 53, 53-A and 54 of the Code of Criminal Procedure,
1973 was amended in 2005 to clarify the scope of medical
examination, especially with regard to the extraction of bodily
substances. The amended provision reads:
164
53. Examination of accused by medical practitioner
at the request of police officer. -
(1) When a person is arrested on a charge of committing
an offence of such a nature and alleged to have been
committed under such circumstances that there are
reasonable grounds for believing that an examination of
his person will afford evidence as to the commission of an
offence, it shall be lawful for a registered medical
practitioner, acting at the request of a police officer not
below the rank of sub-inspector, and for any person
acting in good faith in his aid and under his direction, to
make such an examination of the person arrested as is
reasonably necessary in order to ascertain the facts
which may afford such evidence, and to use such force as
is reasonably necessary for that purpose.
(2) Whenever the person of a female is to be examined
under this section, the examination shall be made only
by, or under the supervision of, a female registered
medical practitioner.
Explanation. - In this section and in sections 53-A and
54, -
(a) `examination' shall include the examination of blood,
blood-stains, semen, swabs in case of sexual offences,
sputum and sweat, hair samples and finger nail
clippings by the use of modern and scientific
techniques including DNA profiling and such other
tests which the registered medical practitioner thinks
necessary in a particular case;
(b)`registered medical practitioner' means a medical
practitioner who possesses any medical qualification
as defined in clause (h) of Section 2 of the Indian
Medical Council Act , 1956 (102 of 1956) and whose
name has been entered in a State Medical Register.
(emphasis supplied)
165
146. The respondents have urged that the impugned
techniques should be read into the relevant provisions - i.e.
Sections 53 and 54 of CrPC. As described earlier, a medical
examination of an arrested person can be directed during the
course of an investigation, either at the instance of the
investigating officer or the arrested person. It has also been
clarified that it is within the powers of a court to direct such a
medical examination on its own. Such an examination can
also be directed in respect of a person who has been released
from custody on bail as well as a person who has been granted
anticipatory bail. Furthermore, Section 53 contemplates the
use of `force as is reasonably necessary' for conducting a
medical examination. This means that once a court has
directed the medical examination of a particular person, it is
within the powers of the investigators and the examiners to
resort to a reasonable degree of physical force for conducting
the same.
147. The contentious provision is the Explanation to Sections
53, 53-A and 54 of the CrPC (amended in 2005) which has
166
been reproduced above. It has been contended that the phrase
`modern and scientific techniques including DNA profiling and
such other tests' should be liberally construed to include the
impugned techniques. It was argued that even though the
narcoanalysis technique, polygraph examination and the
BEAP test have not been expressly enumerated, they could be
read in by examining the legislative intent. Emphasis was
placed on the phrase `and such other tests' to argue that the
Parliament had chosen an approach where the list of `modern
and scientific techniques' contemplated was illustrative and
not exhaustive. It was also argued that in any case, statutory
provisions can be liberally construed in light of scientific
advancements. With the development of newer technologies,
their use can be governed by older statutes which had been
framed to regulate the older technologies used for similar
purposes.
148. On the other hand, the counsel for the appellants have
contended that the Parliament was well aware of the impugned
techniques at the time of the 2005 amendment and
167
consciously chose not to include them in the amended
Explanation to Sections 53, 53-A and 54 of the CrPC. It was
reasoned that this choice recognised the distinction between
testimonial acts and physical evidence. While bodily
substances such as blood, semen, sputum, sweat, hair and
fingernail clippings can be readily characterised as physical
evidence, the same cannot be said for the techniques in
question. This argument was supported by invoking the rule of
`ejusdem generis' which is used in the interpretation of
statutes. This rule entails that the meaning of general words
which follow specific words in a statutory provision should be
construed in light of the commonality between those specific
words. In the present case, the substances enumerated are all
examples of physical evidence. Hence the words `and such
other tests' which appear in the Explanation to Sections 53,
53-A and 54 of the CrPC should be construed to include the
examination of physical evidence but not that of testimonial
acts.
168
149. We are inclined towards the view that the results of the
impugned tests should be treated as testimonial acts for the
purpose of invoking the right against self-incrimination.
Therefore, it would be prudent to state that the phrase `and
such other tests' [which appears in the Explanation to
Sections 53, 53-A and 54 of the CrPC] should be read so as to
confine its meaning to include only those tests which involve
the examination of physical evidence. In pursuance of this line
of reasoning, we agree with the appellant's contention about
the applicability of the rule of `ejusdem generis'. It should also
be noted that the Explanation to Sections 53, 53-A and 54 of
the CrPC does not enumerate certain other forms of medical
examination that involve testimonial acts, such as psychiatric
examination among others. This demonstrates that the
amendment to this provision was informed by a rational
distinction between the examination of physical substances
and testimonial acts.
150. However, the submissions touching on the legislative
intent require some reflection. While it is most likely that the
169
Parliament was well aware of the impugned techniques at the
time of the 2005 amendment to the CrPC and deliberately
chose not to enumerate them, we cannot arrive at a conclusive
finding on this issue. While it is open to courts to examine the
legislative history of a statutory provision, it is not proper for
us to try and conclusively ascertain the legislative intent. Such
an inquiry is impractical since we do not have access to all the
materials which would have been considered by the
Parliament. In such a scenario, we must address the
respondent's arguments about the interpretation of statutes
with regard to scientific advancements. To address this aspect,
we can refer to some extracts from a leading commentary on
the interpretation of statutes [See: Justice G.P. Singh,
Principles of Statutory Interpretation, 10th edn. (New Delhi:
Wadhwa & Co. Nagpur, 2006) at pp. 239-247]. The learned
author has noted, at pp. 240-241:
"Reference to the circumstances existing at the time of
the passing of the statute does not, therefore, mean that
the language used, at any rate, in a modern statute,
should be held to be inapplicable to social, political and
economic developments or to scientific inventions not
known at the time of the passing of the statute. ... The
question again is as to what was the intention of the law
170
makers: Did they intend as originalists may argue, that
the words of the statute be given the meaning they would
have received immediately after the statute's enactment
or did they intend as dynamists may contend that it
would be proper for the court to adopt the current
meaning of the words? The courts have now generally
leaned in favour of dynamic construction. [...] But the
doctrine has also its limitations. For example it does not
mean that the language of an old statute can be
construed to embrace something conceptually different.
The guidance on the question as to when an old statute
can apply to new state of affairs not in contemplation
when the statute was enacted was furnished by Lord
Wilberforce in his dissenting speech in Royal College of
Nursing of the U.K. v. Dept. of Health and Social Security,
(1981) 1 All ER 545, which is now treated as
authoritative. (...) Lord Wilberforce said, at pp. 564-565:
In interpreting an Act of Parliament it is proper, and
indeed necessary, to have regard to the state of
affairs existing, and known by Parliament to be
existing, at the time. It is a fair presumption that
Parliament's policy or intention is directed to that
state of affairs. Leaving aside cases of omission by
inadvertence, this being not such a case when a
new state of affairs, or a fresh set of facts bearing on
policy, comes into existence, the courts have to
consider whether they fall within the parliamentary
intention. They may be held to do so, if they fall
within the same genus of facts as those to which the
expressed policy has been formulated. They may
also be held to do so if there can be detected a clear
purpose in the legislation which can only be fulfilled
if the extension is made. How liberally these
principles may be applied must depend on the
nature of the enactment, and the strictness or
otherwise of the words in which it has been
expressed. The courts should be less willing to
extend expressed meanings if it is clear that the Act
171
in question was designed to be restrictive or
circumscribed in its operation rather than liberal or
permissive. They will be much less willing to do so
where the new subject matter is different in kind or
dimension from that for which the legislation was
passed. In any event there is one course which the
courts cannot take under the law of this country:
they cannot fill gaps; they cannot by asking the
question, `What would Parliament have done in this
current case, not being one in contemplation, if the
facts had been before it?' attempt themselves to
supply the answer, if the answer is not to be found
in the terms of the Act itself."
(internal citations omitted)
151. The learned author has further taken note of several
decisions where general words appearing in statutory
provisions have been liberally interpreted to include newer
scientific inventions and technologies. [Id. at pp. 244-246] The
relevant portion of the commentary quotes Subbarao, J. in
Senior Electric Inspector v. Laxminarayan Chopra, AIR
1962 SC 159, at p. 163:
"It is perhaps difficult to attribute to a legislative body
functioning in a static society that its intention was
couched in terms of considerable breadth so as to take
within its sweep the future developments comprehended
by the phraseology used. It is more reasonable to confine
its intention only to the circumstances obtaining at the
time the law was made. But in modern progressive
society it would be unreasonable to confine the intention
of a Legislature to the meaning attributable to the word
172
used at the time the law was made, for a modern
Legislature making laws to govern society which is fast
moving must be presumed to be aware of an enlarged
meaning the same concept might attract with the march
of time and with the revolutionary changes brought
about in social, economic, political and scientific and
other fields of human activity. Indeed, unless a contrary
intention appears, an interpretation should be given to
the words used to take in new facts and situations, if the
words are capable of comprehending them."
152. In light of this discussion, there are some clear
obstructions to the dynamic interpretation of the amended
Explanation to Sections 53, 53-A and 54 of the CrPC. Firstly,
the general words in question, i.e. `and such other tests'
should ordinarily be read to include tests which are in the
same genus as the other forms of medical examination that
have been specified. Since all the explicit references are to the
examination of bodily substances, we cannot readily construe
the said phrase to include the impugned tests because the
latter seem to involve testimonial responses. Secondly, the
compulsory administration of the impugned techniques is not
the only means for ensuring an expeditious investigation.
Furthermore, there is also a safe presumption that Parliament
was well aware of the existence of the impugned techniques
173
but deliberately chose not to enumerate them. Hence, on an
aggregate understanding of the materials produced before us
we lean towards the view that the impugned tests, i.e. the
narcoanalysis technique, polygraph examination and the
BEAP test should not be read into the provisions for `medical
examination' under the Code of Criminal Procedure, 1973.
153. However, it must be borne in mind that even though the
impugned techniques have not been expressly enumerated in
the CrPC, there is no statutory prohibition against them
either. It is a clear case of silence in the law. Furthermore, in
circumstances where an individual consents to undergo these
tests, there is no dilution of Article 20(3). In the past, the
meaning and scope of the term `investigation' has been held to
include measures that had not been enumerated in statutory
provisions. For example, prior to the enactment of an express
provision for medical examination in the CrPC, it was observed
in Mahipal Maderna v. State of Maharashtra, 1971 Cri L J
1405 (Bom), that an order requiring the production of a hair
sample comes within the ordinary understanding of
174
`investigation' (at pp. 1409-1410, Para. 17). We must also take
note of the decision in Jamshed v. State of Uttar Pradesh,
1976 Cri L J 1680 (All), wherein it was held that a blood
sample can be compulsorily extracted during a `medical
examination' conducted under Section 53 of the CrPC. At that
time, the collection of blood samples was not expressly
contemplated in the said provision. Nevertheless, the Court
had ruled that the phrase `examination of a person' should be
read liberally so as to include an examination of what is
externally visible on a body as well as the examination of an
organ inside the body. [See p. 1689, Para 13]
154. We must also refer back to the substance of the decision
in Sharda v. Dharampal, (supra.) which upheld the authority
of a civil court to order a medical examination in exercise of
the inherent powers vested in it by Section 151 of the Code of
Civil Procedure, 1908. The same reasoning cannot be readily
applied in the criminal context. Despite the absence of a
statutory basis, it is tenable to hold that criminal courts
should be allowed to direct the impugned tests with the
175
subject's consent, keeping in mind that there is no statutory
prohibition against them either.
155. Another pertinent contention raised by the appellants is
that the involvement of medical personnel in the compulsory
administration of the impugned tests is violative of their
professional ethics. In particular, criticism was directed
against the involvement of doctors in the narcoanalysis
technique and it was urged that since the content of the drug-
induced revelations were shared with investigators, this
technique breaches the duty of confidentiality which should be
ordinarily maintained by medical practitioners. [See generally:
Amar Jesani, `Willing participants and tolerant profession:
Medical ethics and human rights in narco-analysis', Indian
Journal of Medical Ethics, Vol. 16(3), July-Sept. 2008] The
counsel have also cited the text of the `Principles of Medical
Ethics' adopted by the United Nations General Assembly [GA
Res. 37/194, 111th Plenary Meeting] on December 18, 1982.
This document enumerates some `Principles of Medical Ethics
relevant to the role of health personnel, particularly physicians,
176
in the protection of prisoners and detainees against torture, and
other cruel, inhuman or degrading treatment of punishment'.
Emphasis was placed on Principle 4 which reads:
Principle 4
It is a contravention of medical ethics for health
personnel, particularly physicians:
To apply their knowledge and skills in order to assist in
the interrogation of prisoners and detainees in a manner
that may adversely affect the physical or mental health or
condition of such prisoners or detainees and which is not
in accordance with the relevant international
instruments;
156. Being a court of law, we do not have the expertise to
mould the specifics of professional ethics for the medical
profession. Furthermore, the involvement of doctors in the
course of investigation in criminal cases has long been
recognised as an exception to the physician-patient privilege.
In the Indian context, the statutory provisions for directing a
medical examination are an example of the same. Fields such
as forensic toxicology have become important in criminal-
justice systems all over the world and doctors are frequently
called on to examine bodily substances such as samples of
blood, hair, semen, saliva, sweat, sputum and fingernail
177
clippings as well as marks, wounds and other physical
characteristics. A reasonable limitation on the forensic uses of
medical expertise is the fact that testimonial acts such as the
results of a psychiatric examination cannot be used as
evidence without the subject's informed consent.
Results of impugned tests should be treated as `personal
testimony'
157. We now return to the operative question of whether the
results obtained through polygraph examination and the BEAP
test should be treated as testimonial responses. Ordinarily
evidence is classified into three broad categories, namely oral
testimony, documents and material evidence. The protective
scope of Article 20(3) read with Section 161(2), CrPC guards
against the compulsory extraction of oral testimony, even at
the stage of investigation. With respect to the production of
documents, the applicability of Article 20(3) is decided by the
trial judge but parties are obliged to produce documents in the
first place. However, the compulsory extraction of material (or
178
physical) evidence lies outside the protective scope of Article
20(3). Furthermore, even testimony in oral or written form can
be required under compulsion if it is to be used for the
purpose of identification or comparison with materials and
information that is already in the possession of investigators.
158. We have already stated that the narcoanalysis test
includes substantial reliance on verbal statements by the test
subject and hence its involuntary administration offends the
`right against self-incrimination'. The crucial test laid down in
Kathi Kalu Oghad, (supra.) is that of `imparting knowledge in
respect of relevant fact by means of oral statements or
statements in writing, by a person who has personal
knowledge of the facts to be communicated to a court or to a
person holding an enquiry or investigation' [Id. at p. 30]. The
difficulty arises since the majority opinion in that case appears
to confine the understanding of `personal testimony' to the
conveyance of personal knowledge through oral statements or
statements in writing. The results obtained from polygraph
examination or a BEAP test are not in the nature of oral or
179
written statements. Instead, inferences are drawn from the
measurement of physiological responses recorded during the
performance of these tests. It could also be argued that tests
such as polygraph examination and the BEAP test do not
involve a `positive volitional act' on part of the test subject and
hence their results should not be treated as testimony.
However, this does not entail that the results of these two tests
should be likened to physical evidence and thereby excluded
from the protective scope of Article 20(3). We must refer back
to the substance of the decision in Kathi Kalu Oghad (supra.)
which equated a testimonial act with the imparting of
knowledge by a person who has personal knowledge of the
facts that are in issue. It has been recognised in other
decisions that such personal knowledge about relevant facts
can also be communicated through means other than oral or
written statements. For example in M.P. Sharma's case
(supra.), it was noted that "...evidence can be furnished
through the lips or by production of a thing or of a document
or in other modes" [Id. at p. 1087]. Furthermore, common
sense dictates that certain communicative gestures such as
180
pointing or nodding can also convey personal knowledge about
a relevant fact, without offering a verbal response. It is quite
foreseeable that such a communicative gesture may by itself
expose a person to `criminal charges or penalties' or furnish a
link in the chain of evidence needed for prosecution.
159. We must also highlight that there is nothing to show that
the learned judges in Kathi Kalu Oghad (supra.) had
contemplated the impugned techniques while discussing the
scope of the phrase `to be a witness' for the purpose of Article
20(3). At that time, the transmission of knowledge through
means other than speech or writing was not something that
could have been easily conceived of. Techniques such as
polygraph examination were fairly obscure and were the
subject of experimentation in some Western nations while the
BEAP technique was developed several years later. Just as the
interpretation of statutes has to be often re-examined in light
of scientific advancements, we should also be willing to re-
examine judicial observations with a progressive lens. An
explicit reference to the Lie-Detector tests was of course made
181
by the U.S. Supreme Court in the Schmerber decision, 384
US 757 (1966), wherein Brennan, J. had observed, at p. 764:
"To compel a person to submit to testing in which an
effort will be made to determine his guilt or innocence on
the basis of physiological responses, whether willed or
not, is to evoke the spirit and history of the Fifth
Amendment."
160. Even though the actual process of undergoing a
polygraph examination or a BEAP test is not the same as that
of making an oral or written statement, the consequences are
similar. By making inferences from the results of these tests,
the examiner is able to derive knowledge from the subject's
mind which otherwise would not have become available to the
investigators. These two tests are different from medical
examination and the analysis of bodily substances such as
blood, semen and hair samples, since the test subject's
physiological responses are directly correlated to mental
faculties. Through lie-detection or gauging a subject's
familiarity with the stimuli, personal knowledge is conveyed in
respect of a relevant fact. It is also significant that unlike the
case of documents, the investigators cannot possibly have any
prior knowledge of the test subject's thoughts and memories,
182
either in the actual or constructive sense. Therefore, even if a
highly-strained analogy were to be made between the results
obtained from the impugned tests and the production of
documents, the weight of precedents leans towards
restrictions on the extraction of `personal knowledge' through
such means.
161. During the administration of a polygraph test or a BEAP
test, the subject makes a mental effort which is accompanied
by certain physiological responses. The measurement of these
responses then becomes the basis of the transmission of
knowledge to the investigators. This knowledge may aid an
ongoing investigation or lead to the discovery of fresh evidence
which could then be used to prosecute the test subject. In any
case, the compulsory administration of the impugned tests
impedes the subject's right to choose between remaining silent
and offering substantive information. The requirement of a
`positive volitional act' becomes irrelevant since the subject is
compelled to convey personal knowledge irrespective of
his/her own volition.
183
162. Some academics have also argued that the results
obtained from tests such as polygraph examination are
`testimonial' acts that should come within the prohibition of
the right against self-incrimination. For instance, Michael S.
Pardo (2008) has observed [Cited from: Michael S. Pardo, `Self-
Incrimination and the Epistemology of Testimony', 30 Cardozo
Law Review 1023-1046 (December 2008) at p. 1046]:
"The results of polygraphs and other lie-detection tests,
whether they call for a voluntary response or not, are
testimonial because the tests are just inductive evidence
of the defendant's epistemic state. They are evidence that
purports to tell us either: (1) that we can or cannot rely
on the assertions made by the defendant and for which
he has represented himself to be an authority, or (2) what
propositions the defendant would assume authority for
and would invite reliance upon, were he to testify
truthfully."
163. Ronald J. Allen and M. Kristin Mace (2004) have offered a
theory that the right against self-incrimination is meant to
protect an individual in a situation where the State places
reliance on the `substantive results of cognition'. The following
definition of `cognition' has been articulated to explain this
position [Cited from: Ronald J. Allen and M. Kristin Mace, `The
184
Self-Incrimination Clause explained and its future predicted',
94 Journal of Criminal Law and Criminology 243-293 (2004),
Fn. 16 at p. 247]:
"... `Cognition' is used herein to refer to these intellectual
processes that allow one to gain and make use of
substantive knowledge and to compare one's `inner world'
(previous knowledge) with the `outside world' (stimuli
such as questions from an interrogator). Excluded are
simple psychological responses to stimuli such as fear,
warmness, and hunger: the mental processes that
produce muscular movements; and one's will or faculty
for choice. ..."
(internal citation omitted)
164. The above-mentioned authors have taken a hypothetical
example where the inferences drawn from an involuntary
polygraph test that did not require verbal answers, led to the
discovery of incriminating evidence. They have argued that if
the scope of the Fifth Amendment extends to protecting the
subject in respect of `substantive results of cognition', then
reliance on polygraph test results would violate the said right.
A similar conclusion has also been made by the National
Human Rights Commission, as evident from the following
extract in the Guidelines Relating to Administration of
Polygraph Test [Lie Detector Test] on an Accused (2000):
185
"The extent and nature of the `self-incrimination' is wide
enough to cover the kinds of statements that were sought
to be induced. In M.P. Sharma, AIR 1954 SC 300, the
Supreme Court included within the protection of the self-
incrimination rule all positive volitional acts which
furnish evidence. This by itself would have made all or
any interrogation impossible. The test - as stated in
Kathi Kalu Oghad (AIR 1961 SC 1808) - retains the
requirement of personal volition and states that `self-
incrimination' must mean conveying information based
upon the personal knowledge of the person giving
information. By either test, the information sought to be
elicited in a Lie Detector Test is information in the
personal knowledge of the accused."
165. In light of the preceding discussion, we are of the view
that the results obtained from tests such as polygraph
examination and the BEAP test should also be treated as
`personal testimony', since they are a means for `imparting
personal knowledge about relevant facts'. Hence, our
conclusion is that the results obtained through the
involuntary administration of either of the impugned tests (i.e.
the narcoanalysis technique, polygraph examination and the
BEAP test) come within the scope of `testimonial compulsion',
thereby attracting the protective shield of Article 20(3).
186
II. Whether the involuntary administration of the
impugned techniques is a reasonable restriction on
`personal liberty' as understood in the context of Article
21 of the Constitution?
166. The preceding discussion does not conclusively address
the contentions before us. Article 20(3) protects a person who
is `formally accused' of having committed an offence or even a
suspect or a witness who is questioned during an investigation
in a criminal case. However, Article 20(3) is not applicable
when a person gives his/her informed consent to undergo any
of the impugned tests. It has also been described earlier that
the `right against self-incrimination' does not protect persons
who may be compelled to undergo the tests in the course of
administrative proceedings or any other proceedings which
may result in civil liability. It is also conceivable that a person
who is forced to undergo these tests may not subsequently
face criminal charges. In this context, Article 20(3) will not
apply in situations where the test results could become the
basis of non-penal consequences for the subject such as
187
custodial abuse, police surveillance and harassment among
others.
167. In order to account for these possibilities, we must
examine whether the involuntary administration of any of
these tests is compatible with the constitutional guarantee of
`substantive due process'. The standard of `substantive due
process' is of course the threshold for examining the validity of
all categories of governmental action that tend to infringe upon
the idea of `personal liberty. We will proceed with this inquiry
with regard to the various dimensions of `personal liberty' as
understood in the context of Article 21 of the Constitution,
which lays down that:
`No person shall be deprived of his life and liberty except
according to procedure established by law'.
168. Since administering the impugned tests entails the
physical confinement of the subject, it is important to consider
whether they can be read into an existing statutory provision.
This is so because any form of restraint on personal liberty,
howsoever slight it may be, must have a basis in law. However,
188
we have already explained how it would not be prudent to read
the explanation to Sections 53, 53-A and 54 of the CrPC in an
expansive manner so as to include the impugned techniques.
The second line of inquiry is whether the involuntary
administration of these tests offends certain rights that have
been read into Article 21 by way of judicial precedents. The
contentions before us have touched on aspects such as the
`right to privacy' and the `right against cruel, inhuman and
degrading treatment'. The third line of inquiry is structured
around the right to fair trial which is an essential component
of `personal liberty'.
169. There are several ways in which the involuntary
administration of either of the impugned tests could be viewed
as a restraint on `personal liberty'. The most obvious indicator
of restraint is the use of physical force to ensure that an
unwilling person is confined to the premises where the tests
are to be conducted. Furthermore, the drug-induced
revelations or the substantive inferences drawn from the
measurement of the subject's physiological responses can be
189
described as an intrusion into the subject's mental privacy. It
is also quite conceivable that a person could make an
incriminating statement on being threatened with the
prospective administration of any of these techniques.
Conversely, a person who has been forcibly subjected to these
techniques could be confronted with the results in a
subsequent interrogation, thereby eliciting incriminating
statements.
170. We must also account for circumstances where a person
who undergoes the said tests is subsequently exposed to
harmful consequences, though not of a penal nature. We have
already expressed our concern with situations where the
contents of the test results could prompt investigators to
engage in custodial abuse, surveillance or undue harassment.
We have also been apprised of some instances where the
investigation agencies have leaked the video-recordings of
narcoanalysis interviews to media organisations. This is an
especially worrisome practice since the public distribution of
these recordings can expose the subject to undue social
190
stigma and specific risks. It may even encourage acts of
vigilantism in addition to a `trial by media'.
171. We must remember that the law does provide for some
restrictions on `personal liberty' in the routine exercise of
police powers. For instance, the CrPC incorporates an
elaborate scheme prescribing the powers of arrest, detention,
interrogation, search and seizure. A fundamental premise of
the criminal justice system is that the police and the judiciary
are empowered to exercise a reasonable degree of coercive
powers. Hence, the provision that enables Courts to order a
person who is under arrest to undergo a medical examination
also provides for the use of `force as is reasonably necessary'
for this purpose. It is evident that the notion of `personal
liberty' does not grant rights in the absolute sense and the
validity of restrictions placed on the same needs to be
evaluated on the basis of criterion such as `fairness, non-
arbitrariness, and reasonableness'.
191
172. Both the appellants and the respondents have cited cases
involving the compelled extraction of blood samples in a
variety of settings. An analogy has been drawn between the
pin-prick of a needle for extracting a blood sample and the
intravenous administration of drugs such as sodium
pentothal. Even though the extracted sample of blood is purely
physical evidence as opposed to a narcoanalysis interview
where the test subject offers testimonial responses, the
comparison can be sustained to examine whether puncturing
the skin with a needle or an injection is an unreasonable
restraint on `personal liberty'.
173. The decision given by the U.S. Supreme Court in Rochin
v. California, 342 US 165 (1952), recognised the threshold of
`conduct that shocks the conscience' for deciding when the
extraction of physical evidence offends the guarantee of `due
process of law'. With regard to the facts in that case, Felix
Frankfurter, J. had decided that the extraction of evidence had
indeed violated the same, Id. at pp. 172-173:
192
" ... we are compelled to conclude that the proceedings by
which this conviction was obtained do more than offend
some fastidious squeamishness or private
sentimentalism about combating crime too energetically.
This is conduct that shocks the conscience. Illegally
breaking into the privacy of the petitioner, the struggle to
open his mouth and remove what was there, the forcible
extraction of his stomach's contents - this course of
proceeding by agents of government to obtain evidence is
bound to offend even hardened sensibilities. They are
methods too close to the rack and the screw to permit of
constitutional differentiation.
... Use of involuntary verbal confessions in State criminal
trials is constitutionally obnoxious not only because of
their unreliability. They are inadmissible under the Due
Process Clause even though statements contained in
them may be independently established as true. Coerced
confessions offend the community's sense of fair play and
decency. So here, to sanction the brutal conduct which
naturally enough was condemned by the court whose
judgment is before us, would be to afford brutality the
cloak of law. Nothing would be more calculated to
discredit law and thereby to brutalize the temper of a
society."
174. Coming to the cases cited before us, in State of
Maharashtra v. Sheshappa Dudhappa Tambade, AIR 1964
Bom 253, the Bombay High Court had upheld the
constitutionality of Section 129-A of the Bombay Prohibition
Act, 1949. This provision empowered prohibition officers and
police personnel to produce a person for `medical
193
examination', which could include the collection of a blood
sample. The said provision authorised the use of `all means
reasonably necessary to secure the production of such person
or the examination of his body or the collection of blood
necessary for the test'. Evidently, the intent behind this
provision was to enforce the policy of prohibition on the
consumption of intoxicating liquors. Among other questions,
the Court also ruled that this provision did not violate Article
21. Reliance was placed on a decision of the U.S. Supreme
Court in Paul H. Breithaupt v. Morris Abram, 352 US 432
(1957), wherein the contentious issue was whether a
conviction on the basis of an involuntary blood-test violated
the guarantee of `due process of law'. In deciding that the
involuntary extraction of the blood sample did not violate the
guarantee of `Due Process of Law', Clark, J. observed, at pp.
435-437:
" ... there is nothing `brutal' or `offensive' in the taking of
a blood sample when done as in this case, under the
protective eye of a physician. To be sure, the driver here
was unconscious when the blood was taken, but the
absence of conscious consent, without more, does not
necessarily render the taking a violation of a
constitutional right and certainly the test administered
194
here would not be considered offensive by even the most
delicate. Furthermore, due process is not measured by
the yardstick of personal reaction or the sphygmogram of
the most sensitive person, but by that whole community
sense of `decency and fairness' that has been woven by
common experience into the fabric of acceptable conduct.
It is on this bedrock that this Court has established the
concept of due process. The blood test procedure has
become routine in our everyday life. It is a ritual for those
going into the military service as well as those applying
for marriage licenses. Many colleges require such tests
before permitting entrance and literally millions of us
have voluntarily gone through the same, though a longer,
routine in becoming blood donors. Likewise, we note that
a majority of our States have either enacted statutes in
some form authorizing tests of this nature or permit
findings so obtained to be admitted in evidence. We
therefore conclude that a blood test taken by a skilled
technician is not such `conduct that shocks the
conscience' [Rochin v. California, 342 US 165, 172
(1952)], nor such a method of obtaining evidence that it
offends a `sense of justice' [Brown v. Mississippi, 297 US
278, 285 (1936)]..."
175. In Jamshed v. State of Uttar Pradesh, 1976 Cri L J
1680 (All), the following observations were made in respect of a
compulsory extraction of blood samples during a medical
examination (in Para 12):
"We are therefore of the view that there is nothing
repulsive or shocking to the conscience in taking the
blood of the appellant in the instant case in order to
establish his guilt. So far as the question of causing hurt
is concerned, even causing of some pain may technically
amount to hurt as defined by Section 319 of the Indian
195
Penal Code. But pain might be caused even if the
accused is subjected to a forcible medical examination.
For example, in cases of rape it may be necessary to
examine the private parts of the culprit. If a culprit is
suspected to have swallowed some stolen article, an
emetic may be used and X-ray examination may also be
necessary. For such purposes the law permits the use of
necessary force. It cannot, therefore, be said that merely
because some pain is caused, such a procedure should
not be permitted."
A similar view was taken in Ananth Kumar Naik v. State of
Andhra Pradesh, 1977 Cri L J 1797 (A.P.), where it was held
(in Para. 20):
" ... In fact S. 53 provides that while making such an
examination such force as is reasonably necessary for
that purpose may be used. Therefore, whatever
discomfort that may be caused when samples of blood
and semen are taken from an arrested person, it is
justified by the provisions of Sections 53 and 54, CrPC."
We can also refer to the following observations in Anil
Anantrao Lokhande v. State of Maharashtra, 1981 Cri L J
125 (Bom), (in Para. 30):
" ... Once it is held that Section 53 of the Code of
Criminal Procedure does confer a right upon the
investigating machinery to get the arrested persons
medically examined by the medical practitioner and the
expression used in Section 53 includes in its import the
taking of sample of the blood for analysis, then obviously
the said provision is not violative of the guarantee
incorporated in Article 21 of the Constitution of India."
196
176. This line of precedents shows that the compelled
extraction of blood samples in the course of a medical
examination does not amount to `conduct that shocks the
conscience'. There is also an endorsement of the view that the
use of `force as may be reasonably necessary' is mandated by
law and hence it meets the threshold of `procedure established
by law'. In this light, we must restate two crucial
considerations that are relevant for the case before us. Firstly,
the restrictions placed on `personal liberty' in the course of
administering the impugned techniques are not limited to
physical confinement and the extraction of bodily substances.
All the three techniques in question also involve testimonial
responses. Secondly, most of the above-mentioned cases were
decided in accordance with the threshold of `procedure
established by law' for restraining `personal liberty'. However,
in this case we must use a broader standard of
reasonableness to evaluate the validity of the techniques in
question. This wider inquiry calls for deciding whether they
are compatible with the various judicially-recognised
197
dimensions of `personal liberty' such as the right to privacy,
the right against cruel, inhuman or degrading treatment and
the right to fair trial.
Applicability of the `right to privacy'
177. In Sharda v. Dharampal, (supra.) this Court had upheld
the power of a civil court to order the medical examination of a
party to a divorce proceeding. In that case, the medical
examination was considered necessary for ascertaining the
mental condition of one of the parties and it was held that a
civil court could direct the same in the exercise of its inherent
powers, despite the absence of an enabling provision. In
arriving at this decision it was also considered whether
subjecting a person to a medical examination would violate
Article 21. We must highlight the fact that a medical test for
ascertaining the mental condition of a person is most likely to
be in the nature of a psychiatric evaluation which usually
includes testimonial responses. Accordingly, a significant part
of that judgment dealt with the `right to privacy'. It would be
198
appropriate to structure the present discussion around
extracts from that opinion.
178. In M.P. Sharma (supra.), it had been noted that the
Indian Constitution did not explicitly include a `right to
privacy' in a manner akin to the Fourth Amendment of the
U.S. Constitution. In that case, this distinction was one of the
reasons for upholding the validity of search warrants issued
for documents required to investigate charges of
misappropriation and embezzlement. Similar issues were
discussed in Kharak Singh v. State of Uttar Pradesh, AIR
1963 SC 1295, where the Court considered the validity of
police-regulations that authorised police personnel to maintain
lists of `history-sheeters' in addition to conducting surveillance
activities, domiciliary visits and periodic inquiries about such
persons. The intention was to monitor persons suspected or
charged with offences in the past, with the aim of preventing
criminal acts in the future. At the time, there was no statutory
basis for these regulations and they had been framed in the
exercise of administrative functions. The majority opinion
199
(Ayyangar, J.) held that these regulations did not violate
`personal liberty', except for those which permitted domiciliary
visits. The other restraints such as surveillance activities and
periodic inquiries about `history-sheeters' were justified by
observing, at Para. 20:
"... the right of privacy is not a guaranteed right under
our Constitution and therefore the attempt to ascertain
the movements of an individual which is merely a
manner in which privacy is invaded is not an
infringement of a fundamental right guaranteed by Part
III."
179. Ayyangar, J. distinguished between surveillance activities
conducted in the routine exercise of police powers and the
specific act of unauthorised intrusion into a person's home
which violated `personal liberty'. However, the minority opinion
(Subba Rao, J.) in Kharak Singh took a different approach by
recognising the interrelationship between Article 21 and 19,
thereby requiring the State to demonstrate the
`reasonableness' of placing such restrictions on `personal
liberty' [This approach was later endorsed by Bhagwati, J. in
Maneka Gandhi v. Union of India, AIR 1978 SC 597, see p.
622]. Subba Rao, J. held that the right to privacy `is an
200
essential ingredient of personal liberty' and that the right to
`personal liberty is `a right of an individual to be free from
restrictions or encroachments on his person, whether those
restrictions or encroachments are directly imposed or
indirectly brought about by calculated measures.' [AIR 1963
SC 1295, at p. 1306]
180. In Gobind v. State of Madhya Pradesh, (1975) 2 SCC
148, the Supreme Court approved of some police-regulations
that provided for surveillance activities, but this time the
decision pointed out a clear statutory basis for these
regulations. However, it was also ruled that the `right to
privacy' was not an absolute right. It was held, at Para. 28:
"The right to privacy in any event will necessarily have to
go through a process of case-by-case development.
Therefore, even assuming that the right to personal
liberty, the right to move freely throughout the territory of
India and the freedom of speech create an independent
right of privacy as an emanation from them which one
can characterize as a fundamental right, we do not think
that the right is absolute."
... Assuming that the fundamental right explicitly
guaranteed to a citizen have penumbral zones and that
the right to privacy is itself a fundamental right, that
201
fundamental right must be subject to restriction on the
basis of compelling public interest."
(at p. 157, Para. 31)
181. Following the judicial expansion of the idea of `personal
liberty', the status of the `right to privacy' as a component of
Article 21 has been recognised and re-inforced. In R. Raj
Gopal v. State of Tamil Nadu, (1994) 6 SCC 632, this Court
dealt with a fact-situation where a convict intended to publish
his autobiography which described the involvement of some
politicians and businessmen in illegal activities. Since the
publication of this work was challenged on grounds such as
the invasion of privacy among others, the Court ruled on the
said issue. It was held that the right to privacy could be
described as the `right to be let alone and a citizen has the
right to safeguard the privacy of his own, his family, marriage,
procreation, motherhood, child-bearing and education among
others. No one can publish anything concerning the above
matters without his consent whether truthful or otherwise and
whether laudatory or critical'. However, it was also ruled that
exceptions may be made if a person voluntarily thrusts himself
202
into a controversy or any of these matters becomes part of
public records or relates to an action of a public official
concerning the discharge of his official duties.
182. In People's Union for Civil Liberties v. Union of India,
AIR 1997 SC 568, it was held that the unauthorised tapping of
telephones by police personnel violated the `right to privacy' as
contemplated under Article 21. However, it was not stated that
telephone-tapping by the police was absolutely prohibited,
presumably because the same may be necessary in some
circumstances to prevent criminal acts and in the course of
investigation. Hence, such intrusive practices are permissible
if done under a proper legislative mandate that regulates their
use. This intended balance between an individual's `right to
privacy' and `compelling public interest' has frequently
occupied judicial attention. Such a compelling public interest
can be identified with the need to prevent crimes and expedite
investigations or to protect public health or morality.
203
183. For example, in X v. Hospital Z, (1998) 8 SCC 296, it
was held that a person could not invoke his `right to privacy' to
prevent a doctor from disclosing his HIV-positive status to
others. It was ruled that in respect of HIV-positive persons, the
duty of confidentiality between the doctor and patient could be
compromised in order to protect the health of other
individuals. With respect to the facts in that case, Saghir
Ahmad, J. held, at Para. 26-28:
"... When a patient was found to be HIV (+), its disclosure
by the Doctor could not be violative of either the rule of
confidentiality or the patient's right of privacy as the lady
with whom the patient was likely to be married was saved
in time by such disclosure, or else, she too would have
been infected with a dreadful disease if marriage had
taken place and been consummated."
184. However, a three judge bench partly overruled this
decision in a review petition. In X v. Hospital Z, (2003) 1 SCC
500, it was held that if an HIV-positive person contracted
marriage with a willing partner, then the same would not
constitute the offences defined by Sections 269 and 270 of the
Indian Penal Code. [Section 269 of the IPC defines the offence
of a `Negligent act likely to spread infection of disease
204
dangerous to life' and Section 270 contemplates a `Malignant
act likely to spread infection of disease dangerous to life'.] A
similar question was addressed by the Andhra Pradesh High
Court in M. Vijaya v. Chairman and Managing Director,
Singareni Collieries Co. Ltd., AIR 2001 AP 502, at pp. 513-
514:
"There is an apparent conflict between the right to
privacy of a person suspected of HIV not to submit
himself forcibly for medical examination and the power
and duty of the State to identify HIV-infected persons for
the purpose of stopping further transmission of the virus.
In the interests of the general public, it is necessary for
the State to identify HIV-positive cases and any action
taken in that regard cannot be termed as
unconstitutional as under Article 47 of the Constitution,
the State was under an obligation to take all steps for the
improvement of the public health. A law designed to
achieve this object, if fair and reasonable, in our opinion,
will not be in breach of Article 21 of the Constitution of
India. ..."
185. The discussion on the `right to privacy' in Sharda v.
Dharampal, (supra.) also cited a decision of the Court of
Appeal (in the U.K.) in R (on the application of S) v. Chief
Constable of South Yorkshire, (2003) 1 All ER 148 (CA). The
contentious issues arose in respect of the retention of
fingerprints and DNA samples taken from persons who had
205
been suspected of having committed offences in the past but
were not convicted for them. It was argued that this policy
violated Articles 8 and 14 of the European Convention on
Human Rights and Fundamental Freedoms, 1950 [Hereinafter
`EctHR]. Article 8 deals with the `Right to respect for private
and family life' while Article 14 lays down the scope of the
`Prohibition Against Discrimination'. For the present
discussion, it will be useful to examine the language of Article
8 of the EctHR:-
Article 8 - Right to respect for private and family life
1. Everyone has the right to respect for his private and
family life, his home and his correspondence.
2. There shall be no interference by a public authority
with the exercise of this right except such as is in
accordance with the law and is necessary in a democratic
society in the interests of national security, public safety
or the economic well-being of the country, for the
prevention of disorder or crime, for the protection of
health or morals, or for the protection of the rights and
freedoms of others.
186. In that case, a distinction was drawn between the
`taking', `retention' and `use' of fingerprints and DNA samples.
While the `taking' of such samples from individual suspects
could be described as a reasonable measure in the course of
206
routine police functions, the controversy arose with respect to
the `retention' of samples taken from individuals who had been
suspected of having committing offences in the past but had
not been convicted for them. The statutory basis for the
retention of physical samples taken from suspects was Section
64(1A) of the Police and Criminal Evidence Act, 1984. This
provision also laid down that these samples could only be
used for purposes related to the `prevention or detection of
crime, the investigation of an offence or the conduct of a
prosecution'. This section had been amended to alter the older
position which provided that physical samples taken from
suspects were meant to be destroyed once the suspect was
cleared of the charges or acquitted. As per the older position, it
was only the physical samples taken from convicted persons
which could be retained by the police authorities. It was
contended that the amended provision was incompatible with
Articles 8 and 14 of the EctHR and hence the relief sought was
that the fingerprints and DNA samples of the concerned
parties should be destroyed.
207
187. In response to these contentions, the majority (Lord
Woolf, C.J.) held that although the retention of such material
interfered with the Art. 8(1) rights of the individuals (`right to
respect for private and family life') from whom it had been
taken, that interference was justified by Art. 8(2). It was
further reasoned that the purpose of the impugned
amendment, the language of which was very similar to Art.
8(2), was obvious and lawful. Nor were the adverse
consequences to the individual disproportionate to the benefit
to the public. It was held, at Para. 17:
"So far as the prevention and detection of crime is
concerned, it is obvious the larger the databank of
fingerprints and DNA samples available to the police, the
greater the value of the databank will be in preventing
crime and detecting those responsible for crime. There
can be no doubt that if every member of the public was
required to provide fingerprints and a DNA sample this
would make a dramatic contribution to the prevention
and detection of crime. To take but one example, the
great majority of rapists who are not known already to
their victim would be able to be identified. However, the
1984 Act does not contain blanket provisions either as to
the taking, the retention, or the use of fingerprints or
samples; Parliament has decided upon a balanced
approach."
208
Lord Woolf, C.J. also referred to the following observations
made by Lord Steyn in an earlier decision of the House of
Lords, which was reported as Attorney General's Reference
(No. 3 of 1999), (2001) 1 All ER 577, at p. 584:
"... It must be borne in mind that respect for the privacy
of defendants is not the only value at stake. The purpose
of the criminal law is to permit everyone to go about their
daily lives without fear of harm to person or property.
And it is in the interests of everyone that serious crime
should be effectively investigated and prosecuted. There
must be fairness to all sides. In a criminal case this
requires the court to consider a triangulation of interests.
It involves taking into account the position of the
accused, the victim and his or her family, and the
public."
On the question of whether the retention of material samples
collected from suspects who had not been convicted was
violative of the `Prohibition against Discrimination' under Art.
14 of the EctHR, it was observed, (2003) 1 All ER 148 (CA), at
p. 162:
"In the present circumstances when an offence is being
investigated or is the subject of a charge it is accepted
that fingerprints and samples may be taken. Where they
have not been taken before any question of the retention
arises, they have to be taken so there would be the
additional interference with their rights which the taking
involves. As no harmful consequences will flow from the
retention unless the fingerprints or sample match those
209
of someone alleged to be responsible for an offence, the
different treatment is fully justified."
188. In the present case, written submissions made on behalf
of the respondents have tried to liken the compulsory
administration of the impugned techniques with the DNA
profiling technique. In light of this attempted analogy, we must
stress that the DNA profiling technique has been expressly
included among the various forms of medical examination in
the amended explanation to Sections 53, 53-A and 54 of the
CrPC. It must also be clarified that a `DNA profile' is different
from a DNA sample which can be obtained from bodily
substances. A DNA profile is a record created on the basis of
DNA samples made available to forensic experts. Creating and
maintaining DNA profiles of offenders and suspects are useful
practices since newly obtained DNA samples can be readily
matched with existing profiles that are already in the
possession of law-enforcement agencies. The matching of DNA
samples is emerging as a vital tool for linking suspects to
specific criminal acts. It may also be recalled that the as per
the majority decision in Kathi Kalu Oghad, (supra.) the use
210
of material samples such as fingerprints for the purpose of
comparison and identification does not amount to a
testimonial act for the purpose of Article 20(3). Hence, the
taking and retention of DNA samples which are in the nature
of physical evidence does not face constitutional hurdles in the
Indian context. However, if the DNA profiling technique is
further developed and used for testimonial purposes, then
such uses in the future could face challenges in the judicial
domain.
189. The judgment delivered in Sharda v. Dharampal,
(supra.) had surveyed the above-mentioned decisions to
conclude that a person's right to privacy could be justifiably
curtailed if it was done in light of competing interests.
Reference was also made to some statutes that permitted the
compulsory administration of medical tests. For instance, it
was observed, at Para. 61-62:
"Having outlined the law relating to privacy in India, it is
relevant in this context to notice that certain laws have
been enacted by the Indian Parliament where the
accused may be subjected to certain medical or other
tests.
211
By way of example, we may refer to Sections 185, 202,
203 and 204 of the Motor Vehicles Act, Sections 53 and
54 of the Code of Criminal Procedure and Section 3 of the
Identification of Prisoners Act, 1920. Reference in this
connection may also be made to Sections 269 and 270 of
the Indian Penal Code. Constitutionality of these laws, if
challenge is thrown, may be upheld."
190. However, it is important for us to distinguish between the
considerations that occupied this Court's attention in Sharda
v. Dharampal, (supra.) and the ones that we are facing in the
present case. It is self-evident that the decision did not to
dwell on the distinction between medical tests whose results
are based on testimonial responses and those tests whose
results are based on the analysis of physical characteristics
and bodily substances. It can be safely stated that the Court
did not touch on the distinction between testimonial acts and
physical evidence, simply because Article 20(3) is not
applicable to a proceeding of a civil nature.
191. Moreover, a distinction must be made between the
character of restraints placed on the right to privacy. While the
ordinary exercise of police powers contemplates restraints of a
212
physical nature such as the extraction of bodily substances
and the use of reasonable force for subjecting a person to a
medical examination, it is not viable to extend these police
powers to the forcible extraction of testimonial responses. In
conceptualising the `right to privacy' we must highlight the
distinction between privacy in a physical sense and the
privacy of one's mental processes.
192. So far, the judicial understanding of privacy in our
country has mostly stressed on the protection of the body and
physical spaces from intrusive actions by the State. While the
scheme of criminal procedure as well as evidence law
mandates interference with physical privacy through statutory
provisions that enable arrest, detention, search and seizure
among others, the same cannot be the basis for compelling a
person `to impart personal knowledge about a relevant fact'.
The theory of interrelationship of rights mandates that the
right against self-incrimination should also be read as a
component of `personal liberty' under Article 21. Hence, our
understanding of the `right to privacy' should account for its
213
intersection with Article 20(3). Furthermore, the `rule against
involuntary confessions' as embodied in Sections 24, 25, 26
and 27 of the Evidence Act, 1872 seeks to serve both the
objectives of reliability as well as voluntariness of testimony
given in a custodial setting. A conjunctive reading of Articles
20(3) and 21 of the Constitution along with the principles of
evidence law leads us to a clear answer. We must recognise
the importance of personal autonomy in aspects such as the
choice between remaining silent and speaking. An individual's
decision to make a statement is the product of a private choice
and there should be no scope for any other individual to
interfere with such autonomy, especially in circumstances
where the person faces exposure to criminal charges or
penalties.
193. Therefore, it is our considered opinion that subjecting a
person to the impugned techniques in an involuntary manner
violates the prescribed boundaries of privacy. Forcible
interference with a person's mental processes is not provided
for under any statute and it most certainly comes into conflict
214
with the `right against self-incrimination'. However, this
determination does not account for circumstances where a
person could be subjected to any of the impugned tests but
not exposed to criminal charges and the possibility of
conviction. In such cases, he/she could still face adverse
consequences such as custodial abuse, surveillance, undue
harassment and social stigma among others. In order to
address such circumstances, it is important to examine some
other dimensions of Article 21.
Safeguarding the `right against cruel, inhuman or
degrading treatment'
194. We will now examine whether the act of forcibly
subjecting a person to any of the impugned techniques
constitutes `cruel, inhuman or degrading treatment', when
considered by itself. This inquiry will account for the
permissibility of these techniques in all settings, including
those where a person may not be subsequently prosecuted but
could face adverse consequences of a non-penal nature. The
appellants have contended that the use of the impugned
215
techniques amounts to `cruel, inhuman or degrading
treatment'. Even though the Indian Constitution does not
explicitly enumerate a protection against `cruel, inhuman or
degrading punishment or treatment' in a manner akin to the
Eighth Amendment of the U.S. Constitution, this Court has
discussed this aspect in several cases. For example, in Sunil
Batra v. Delhi Administration, (1978) 4 SCC 494, V.R.
Krishna Iyer, J. observed at pp. 518-519:
"True, our Constitution has no `due process' clause or the
VIII Amendment; but, in this branch of law, after Cooper
[(1970) 1 SCC 248] and Maneka Gandhi, [(1978) 1 SCC
248] the consequence is the same. For what is punitively
outrageous, scandalizingly unusual or cruel and
rehabilitatively counter-productive, is unarguably
unreasonable and arbitrary and is shot down by Article
14 and 19 and if inflicted with procedural unfairness,
falls foul of Article 21. Part III of the Constitution does
not part company with the prisoner at the gates, and
judicial oversight protects the prisoner's shrunken
fundamental rights, if flouted, frowned upon or frozen by
the prison authority. Is a person under death sentence or
undertrial unilaterally dubbed dangerous liable to suffer
extra torment too deep for tears? Emphatically no, lest
social justice, dignity of the individual, equality before the
law, procedure established by law and the seven lamps of
freedom (Article 19) become chimerical constitutional
claptrap. Judges, even within a prison setting, are the
real, though restricted, ombudsmen empowered to
proscribe and prescribe, humanize and civilize the life-
style within the carcers. The operation of Articles 14, 19
216
and 21 may be pared down for a prisoner but not puffed
out altogether. ...."
195. In the above-mentioned case, this Court had disapproved
of practices such as solitary-confinement and the use of bar-
fetters in prisons. It was held that prisoners were also entitled
to `personal liberty' though in a limited sense, and hence
judges could enquire into the reasonableness of their
treatment by prison-authorities. Even though `the right
against cruel, inhuman and degrading punishment' cannot be
asserted in an absolute sense, there is a sufficient basis to
show that Article 21 can be invoked to protect the `bodily
integrity and dignity' of persons who are in custodial
environments. This protection extends not only to prisoners
who are convicts and under-trials, but also to those persons
who may be arrested or detained in the course of
investigations in criminal cases. Judgments such as D.K.
Basu v. State of West Bengal, AIR 1997 SC 610, have
stressed upon the importance of preventing the `cruel,
inhuman or degrading treatment' of any person who is taken
into custody. In respect of the present case, any person who is
217
forcibly subjected to the impugned tests in the environs of a
forensic laboratory or a hospital would be effectively in a
custodial environment for the same. The presumption of the
person being in a custodial environment will apply irrespective
of whether he/she has been formally accused or is a suspect
or a witness. Even if there is no overbearing police presence,
the fact of physical confinement and the involuntary
administration of the tests is sufficient to constitute a
custodial environment for the purpose of attracting Article
20(3) and Article 21. It was necessary to clarify this aspect
because we are aware of certain instances where persons are
questioned in the course of investigations without being
brought on the record as witnesses. Such omissions on part of
investigating agencies should not be allowed to become a
ground for denying the protections that are available to a
person in custody.
196. The appellants have also drawn our attention to some
international conventions and declarations. For instance in
218
the Universal Declaration of Human Rights [GA Res. 217 A (III)
of December 10 1948], Article 5 states that:
"No one shall be subjected to torture or to cruel,
inhuman or degrading treatment or punishment."
Article 7 of the International Covenant on Civil and Political
Rights (ICCPR) [GA Res. 2200A (XXI), entered into force March
23, 1976] also touches on the same aspect. It reads as follows:
"...No one shall be subjected to torture or to cruel,
inhuman or degrading treatment or punishment. In
particular, no one shall be subjected without his free
consent to medical or scientific experimentation."
Special emphasis was placed on the definitions of `torture' as
well as `cruel, inhuman or degrading treatment or punishment'
in Articles 1 and 16 of the Convention Against Torture and
other Cruel, Inhuman or Degrading Treatment or Punishment,
1984.
Article 1
1. For the purposes of this Convention, torture means
any act by which severe pain or suffering, whether
physical or mental, is intentionally inflicted on a person
for such purposes as obtaining from him or a third
person information or a confession, punishing him for an
act he or a third person has committed or is suspected of
having committed, or intimidating or coercing him or a
third person, or for any reason based on discrimination
of any kind, when such pain or suffering is inflicted by or
219
at the instigation of or with the consent or acquiescence
of a public official or other person acting in an official
capacity. It does not include pain or suffering arising only
from, inherent in or incidental to lawful sanctions.
2. This article is without prejudice to any international
instrument or national legislation which does or may
contain provisions of wider application.
Article 16
1. Each State Party shall undertake to prevent in any
territory under its jurisdiction other acts of cruel,
inhuman or degrading treatment or punishment which
do not amount to torture as defined in Article 1, when
such acts are committed by or at the instigation of or
with the consent or acquiescence of a public official or
other person acting in an official capacity. In particular,
the obligations contained in Article 10, 11 , 12 and 13
shall apply with the substitution for references to torture
or references to other forms of cruel, inhuman or
degrading treatment or punishment.
2. The provisions of this Convention are without
prejudice to the provisions of any other international
instrument or national law which prohibit cruel,
inhuman or degrading treatment or punishment or which
relate to extradition or expulsion.
197. We were also alerted to the Body of Principles for the
Protection of all persons under any form of Detention or
Imprisonment [GA Res. 43/173, 76th plenary meeting, 9
December 1988] which have been adopted by the United
Nations General Assembly. Principles 1, 6 and 21 hold
relevance for us:
220
Principle 1
All persons under any form of detention or imprisonment
shall be treated in a humane manner and with respect
for the inherent dignity of the human person.
Principle 6
No person under any form of detention or imprisonment
shall be subjected to torture or to cruel, inhuman or
degrading treatment or punishment. No circumstance
whatever may be invoked as a justification for torture or
other cruel, inhuman or degrading treatment or
punishment.
The term `cruel, inhuman or degrading treatment or
punishment' should be interpreted so as to extend the
widest possible protection against abuses, whether
physical or mental, including the holding of a detained or
imprisoned person in conditions which deprive him,
temporarily or permanently, of the use of any of his
natural senses, such as sight or hearing, or of his
awareness of place and the passing of time.
Principle 21
1. It shall be prohibited to take undue advantage of the
situation of a detained or imprisoned person for the
purpose of compelling him to confess, to incriminate
himself otherwise or to testify against any other person.
2. No detained person while being interrogated shall be
subjected to violence, threats or methods of interrogation
which impair his capacity of decision or judgment.
198. It was shown that protections against torture and `cruel,
inhuman or degrading treatment or punishment' are accorded
to persons who are arrested or detained in the course of armed
conflicts between nations. In the Geneva Convention relative to
221
the Treatment of Prisoners of War (entry into force 21 October
1950) the relevant extract reads:
Article 17
... No physical or mental torture, nor any other form of
coercion, may be inflicted on prisoners of war to secure
from them information of any kind whatever. Prisoners of
war who refuse to answer may not be threatened,
insulted, or exposed to any unpleasant or
disadvantageous treatment of any kind. ...
199. Having surveyed these materials, it is necessary to clarify
that we are not absolutely bound by the contents of the
Convention Against Torture and Other Cruel, Inhuman or
Degrading Treatment or Punishment (1984) [Hereinafter
`Torture Convention'] This is so because even though India is a
signatory to this Convention, it has not been ratified by
Parliament in the manner provided under Article 253 of the
Constitution and neither do we have a national legislation
which has provisions analogous to those of the Torture
Convention. However, these materials do hold significant
persuasive value since they represent an evolving international
consensus on the nature and specific contents of human
rights norms.
222
200. The definition of torture indicates that the threshold for
the same is the intentional infliction of physical or mental pain
and suffering, by or at the instance of a public official for the
purpose of extracting information or confessions. `Cruel,
Inhuman or Degrading Treatment' has been defined as
conduct that does not amount to torture but is wide enough to
cover all kinds of abuses. Hence, proving the occurrence of
`cruel, inhuman or degrading treatment' would require a lower
threshold than that of torture. In addition to highlighting these
definitions, the counsel for the appellants have submitted that
causing physical pain by injecting a drug can amount to
`Injury' as defined by Section 44 of the IPC or `Hurt' as defined
in Section 319 of the same Code.
201. In response, the counsel for the respondents have drawn
our attention to literature which suggests that in the case of
the impugned techniques, the intention on part of the
investigators is to extract information and not to inflict any
pain or suffering. Furthermore, it has been contended that the
223
actual administration of either the narcoanalysis technique,
polygraph examination or the BEAP test does not involve a
condemnable degree of `physical pain or suffering'. Even
though some physical force may be used or threats may be
given to compel a person to undergo the tests, it was argued
that the administration of these tests ordinarily does not
result in physical injuries. [See: Linda M. Keller, `Is Truth
Serum Torture?' 20 American University International Law
Review 521-612 (2005)] However, it is quite conceivable that
the administration of any of these techniques could involve the
infliction of `mental pain or suffering' and the contents of their
results could expose the subject to physical abuse. When a
person undergoes a narcoanalysis test, he/she is in a half-
conscious state and subsequently does not remember the
revelations made in a drug-induced state. In the case of
polygraph examination and the BEAP test, the test subject
remains fully conscious during the tests but does not
immediately know the nature and implications of the results
derived from the same. However, when he/she later learns
about the contents of the revelations, they may prove to be
224
incriminatory or be in the nature of testimony that can be
used to prosecute other individuals. We have also highlighted
the likelihood of a person making incriminatory statements
when he/she is subsequently confronted with the test results.
The realisation of such consequences can indeed cause
`mental pain or suffering' for the person who was subjected to
these tests. The test results could also support the theories or
suspicions of the investigators in a particular case. These
results could very well confirm suspicions about a person's
involvement in a criminal act. For a person in custody, such
confirmations could lead to specifically targeted behaviour
such as physical abuse. In this regard, we have repeatedly
expressed our concern with situations where the test results
could trigger undesirable behaviour.
202. We must also contemplate situations where a threat
given by the investigators to conduct any of the impugned
tests could prompt a person to make incriminatory statements
or to undergo some mental trauma. Especially in cases of
individuals from weaker sections of society who are unaware
225
of their fundamental rights and unable to afford legal advice,
the mere apprehension of undergoing scientific tests that
supposedly reveal the truth could push them to make
confessional statements. Hence, the act of threatening to
administer the impugned tests could also elicit testimony. It is
also quite conceivable that an individual may give his/her
consent to undergo the said tests on account of threats, false
promises or deception by the investigators. For example, a
person may be convinced to give his/her consent after being
promised that this would lead to an early release from custody
or dropping of charges. However, after the administration of
the tests the investigators may renege on such promises. In
such a case the relevant inquiry is not confined to the
apparent voluntariness of the act of undergoing the tests, but
also includes an examination of the totality of circumstances.
203. Such a possibility had been outlined by the National
Human Rights Commission which had published `Guidelines
relating to administration of Polygraph test (Lie Detector test) on
226
an accused (2000)'. The relevant extract has been reproduced
below:
"... The lie detector test is much too invasive to admit of
the argument that the authority for Lie Detector tests
comes from the general power to interrogate and answer
questions or make statements. (Ss. 160-167 CrPC)
However, in India we must proceed on the assumption of
constitutional invasiveness and evidentiary
impermissiveness to take the view that such holding of
tests is a prerogative of the individual, not an
empowerment of the police. In as much as this invasive
test is not authorised by law, it must perforce be
regarded as illegal and unconstitutional unless it is
voluntarily undertaken under non-coercive
circumstances. If the police action of conducting a lie
detector test is not authorised by law and impermissible,
the only basis on which it could be justified is, if it is
volunteered. There is a distinction between: (a)
volunteering, and (b) being asked to volunteer. This
distinction is of some significance in the light of the
statutory and constitutional protections available to any
person. There is a vast difference between a person
saying, `I wish to take a lie detector test because I wish to
clear my name', and when a person is told by the police,
`If you want to clear your name, take a lie detector test'. A
still worse situation would be where the police say, `Take
a lie detector test, and we will let you go'. In the first
example, the person voluntarily wants to take the test. It
would still have to be examined whether such
volunteering was under coercive circumstances or not. In
the second and third examples, the police implicitly (in
the second example) and explicitly (in the third example)
link up the taking of the lie detector test to allowing the
accused to go free."
227
204. We can also contemplate a possibility that even when an
individual freely consents to undergo the tests in question, the
resulting testimony cannot be readily characterised as
voluntary in nature. This is attributable to the differences
between the manner in which the impugned tests are
conducted and an ordinary interrogation. In an ordinary
interrogation, the investigator asks questions one by one and
the subject has the choice of remaining silent or answering
each of these questions. This choice is repeatedly exercised
after each question is asked and the subject decides the
nature and content of each testimonial response. On account
of the continuous exercise of such a choice, the subject's
verbal responses can be described as voluntary in nature.
However, in the context of the impugned techniques the test
subject does not exercise such a choice in a continuous
manner. After the initial consent is given, the subject has no
conscious control over the subsequent responses given during
the test. In case of the narcoanalysis technique, the subject
speaks in a drug-induced state and is clearly not aware of
his/her own responses at the time. In the context of polygraph
228
examination and the BEAP tests, the subject cannot anticipate
the contents of the `relevant questions' that will be asked or
the `probes' that will be shown. Furthermore, the results are
derived from the measurement of physiological responses and
hence the subject cannot exercise an effective choice between
remaining silent and imparting personal knowledge. In light of
these facts, it was contended that a presumption cannot be
made about the voluntariness of the test results even if the
subject had given prior consent. In this respect, we can re-
emphasize Principle 6 and 21 of the Body of Principles for the
Protection of all persons under any form of Detention or
Imprisonment (1988). The explanation to Principle 6 provides
that:
"The term `cruel, inhuman or degrading treatment or
punishment' should be interpreted so as to extend the
widest possible protection against abuses, whether
physical or mental, including the holding of a detained or
imprisoned person in conditions which deprive him,
temporarily or permanently, of the use of any of his
natural senses, such as sight or hearing, or of his
awareness of place and the passing of time."
Furthermore, Principle 21(2) lays down that:
229
"No detained person while being interrogated shall be
subjected to violence, threats or methods of interrogation
which impair his capacity of decision or judgment."
205. It is undeniable that during a narcoanalysis interview,
the test subject does lose `awareness of place and passing of
time'. It is also quite evident that all the three impugned
techniques can be described as methods of interrogation
which impair the test subject's `capacity of decision or
judgment'. Going by the language of these principles, we hold
that the compulsory administration of the impugned
techniques constitutes `cruel, inhuman or degrading
treatment' in the context of Article 21. It must be remembered
that the law disapproves of involuntary testimony, irrespective
of the nature and degree of coercion, threats, fraud or
inducement used to elicit the same. The popular perceptions
of terms such as `torture' and `cruel, inhuman or degrading
treatment' are associated with gory images of blood-letting and
broken bones. However, we must recognise that a forcible
intrusion into a person's mental processes is also an affront to
human dignity and liberty, often with grave and long-lasting
230
consequences. [A similar conclusion has been made in the
following paper: Marcy Strauss, `Criminal Defence in the Age
of Terrorism - Torture', 48 New York Law School Law Review
201-274 (2003/2004)]
206. It would also be wrong to sustain a comparison between
the forensic uses of these techniques and the practice of
medicine. It has been suggested that patients undergo a
certain degree of `physical or mental pain and suffering' on
account of medical interventions such as surgeries and drug-
treatments. However, such interventions are acceptable since
the objective is to ultimately cure or prevent a disease or
disorder. So it is argued that if the infliction of some `pain and
suffering' is permitted in the medical field, it should also be
tolerated for the purpose of expediting investigations in
criminal cases. This is the point where our constitutional
values step in. A society governed by rules and liberal values
makes a rational distinction between the various
circumstances where individuals face pain and suffering.
While the infliction of a certain degree of pain and suffering is
231
mandated by law in the form of punishments for various
offences, the same cannot be extended to all those who are
questioned during the course of an investigation. Allowing the
same would vest unlimited discretion and lead to the
disproportionate exercise of police powers.
Incompatibility with the `Right to fair trial'
207. The respondents' position is that the compulsory
administration of the impugned techniques should be
permitted at least for investigative purposes, and if the test
results lead to the discovery of fresh evidence, then these
fruits should be admissible. We have already explained in light
of the conjunctive reading of Article 20(3) of the Constitution
and Section 27 of the Evidence Act, that if the fact of
compulsion is proved, the test results will not be admissible as
evidence. However, for the sake of argument, if we were to
agree with the respondents and allow investigators to compel
individuals to undergo these tests, it would also affect some of
the key components of the `right to fair trial'.
232
208. The decision of this Court in D.K. Basu v. State of West
Bengal, AIR 1997 SC 610, had stressed upon the entitlement
of a person in custody to consult a lawyer. Access to legal
advice is an essential safeguard so that an individual can be
adequately apprised of his constitutional and statutory rights.
This is also a measure which checks custodial abuses.
However, the involuntary administration of any of the
impugned tests can lead to a situation where such legal advice
becomes ineffective. For instance even if a person receives the
best of legal advice before undergoing any of these tests, it
cannot prevent the extraction of information which may prove
to be inculpatory by itself or lead to the subsequent discovery
of incriminating materials. Since the subject has no conscious
control over the drug-induced revelations or substantive
inferences, the objective of providing access to legal advice are
frustrated.
209. Since the subject is not immediately aware of the
contents of the drug-induced revelations or substantive
inferences, it also conceivable that the investigators may chose
233
not to communicate them to the subject even after completing
the tests. In fact statements may be recorded or charges
framed without the knowledge of the test subject. At the stage
of trial, the prosecution is obliged to supply copies of all
incriminating materials to the defendant but reliance on the
impugned tests could curtail the opportunity of presenting a
meaningful and wholesome defence. If the contents of the
revelations or inferences are communicated much later to the
defendant, there may not be sufficient time to prepare an
adequate defence.
210. Earlier in this judgment, we had surveyed some foreign
judicial precedents dealing with each of the tests in question.
A common concern expressed with regard to each of these
techniques was the questionable reliability of the results
generated by them. In respect of the narcoanalysis technique,
it was observed that there is no guarantee that the drug-
induced revelations will be truthful. Furthermore, empirical
studies have shown that during the hypnotic stage,
individuals are prone to suggestibility and there is a good
234
chance that false results could lead to a finding of guilt or
innocence. As far as polygraph examination is concerned,
though there are some studies showing improvements in the
accuracy of results with advancement in technology, there is
always scope for error on account of several factors.
Objections can be raised about the qualifications of the
examiner, the physical conditions under which the test was
conducted, the manner in which questions were framed and
the possible use of `countermeasures' by the test subject. A
significant criticism of polygraphy is that sometimes the
physiological responses triggered by feelings such as anxiety
and fear could be misread as those triggered by deception.
Similarly, with the P300 Waves test there are inherent
limitations such as the subject having had `prior exposure' to
the `probes' which are used as stimuli. Furthermore, this
technique has not been the focus of rigorous independent
studies. The questionable scientific reliability of these
techniques comes into conflict with the standard of proof
`beyond reasonable doubt' which is an essential feature of
criminal trials.
235
211. Another factor that merits attention is the role of the
experts who administer these tests. While the consideration of
expert opinion testimony has become a mainstay in our
criminal justice system with the advancement of fields such as
forensic toxicology, questions have been raised about the
credibility of experts who are involved in administering the
impugned techniques. It is a widely accepted principle for
evaluating the validity of any scientific technique that it
should have been subjected to rigorous independent studies
and peer review. This is so because the persons who are
involved in the invention and development of certain
techniques are perceived to have an interest in their
promotion. Hence, it is quite likely that such persons may give
unduly favourable responses about the reliability of the
techniques in question.
212. Even though India does not have a jury system, the use
of the impugned techniques could impede the fact-finding role
of a trial judge. This is a special concern in our legal system,
236
since the same judge presides over the evidentiary phase of
the trial as well as the guilt phase. The consideration of the
test results or their fruits for the purpose of deciding on their
admissibility could have a prejudicial effect on the judge's
mind even if the same are not eventually admitted as evidence.
Furthermore, we echo the concerns expressed by the Supreme
Court of Canada in R v. Beland, [1987] 36 C.C.C. (3d) 481,
where it was observed that reliance on scientific techniques
could cloud human judgment on account of an `aura of
infallibility'. While judges are expected to be impartial and
objective in their evaluation of evidence, one can never
discount the possibility of undue public pressure in some
cases, especially when the test results appear to be
inculpatory. We have already expressed concerns with
situations where media organisations have either circulated
the video-recordings of narcoanalysis interviews or
broadcasted dramatized re-constructions, especially in
sensational criminal cases.
237
213. Another important consideration is that of ensuring
parity between the procedural safeguards that are available to
the prosecution and the defence. If we were to permit the
compulsory administration of any of the impugned techniques
at the behest of investigators, there would be no principled
basis to deny the same opportunity to defendants as well as
witnesses. If the investigators could justify reliance on these
techniques, there would be an equally compelling reason to
allow the indiscrete administration of these tests at the
request of convicts who want re-opening of their cases or even
for the purpose of attacking and rehabilitating the credibility
of witnesses during a trial. The decision in United States v.
Scheffer, 523 US 303 (1998), has highlighted the concerns
with encouraging litigation that is collateral to the main facts
in issue. We are of the view that an untrammelled right of
resorting to the techniques in question will lead to an
unnecessary rise in the volume of frivolous litigation before
our Courts.
238
214. Lastly, we must consider the possibility that the victims
of offences could be forcibly subjected to any of these
techniques during the course of investigation. We have already
highlighted a provision in the Laboratory Procedure Manual for
Polygraph tests which contemplates the same for ascertaining
the testimony of victims of sexual offences. In light of the
preceding discussion, it is our view that irrespective of the
need to expedite investigations in such cases, no person who
is a victim of an offence can be compelled to undergo any of
the tests in question. Such a forcible administration would be
an unjustified intrusion into mental privacy and could lead to
further stigma for the victim.
Examining the `compelling public interest'
215. The respondents have contended that even if the
compulsory administration of the impugned techniques
amounts to a seemingly disproportionate intrusion into
personal liberty, their investigative use is justifiable since
there is a compelling public interest in eliciting information
that could help in preventing criminal activities in the future.
239
Such utilitarian considerations hold some significance in light
of the need to combat terrorist activities, insurgencies and
organised crime. It has been argued that such exigencies
justify some intrusions into civil liberties. The textual basis for
these restraints could be grounds such as preserving the
`sovereignty and integrity of India', `the security of the state'
and `public order' among others. It was suggested that if
investigators are allowed to rely on these tests, the results
could help in uncovering plots, apprehending suspects and
preventing armed attacks as well as the commission of
offences. Reference was also made to the frequently discussed
`Ticking Bomb' scenario. This hypothetical situation examines
the choices available to investigators when they have reason to
believe that the person whom they are interrogating is aware
of the location of a bomb. The dilemma is whether it is
justifiable to use torture or other improper means for eliciting
information which could help in saving the lives of ordinary
citizens. [The arguments for the use of `truth serums' in such
situations have been examined in the following articles: Jason
R. Odeshoo, `Truth or Dare?: Terrorism and Truth Serum in
240
the Post- 9/11 World, 57 Stanford Law Review 209-255
(October 2004); Kenneth Lasson, `Torture, Truth Serum, and
Ticking Bombs: Toward a pragmatic perspective on coercive
interrogation', 39 Loyola University Chicago Law Journal 329-
360 (Winter 2008)]
216. While these arguments merit consideration, it must be
noted that ordinarily it is the task of the legislature to arrive at
a pragmatic balance between the often competing interests of
`personal liberty' and public safety. In our capacity as a
constitutional court, we can only seek to preserve the balance
between these competing interests as reflected in the text of
the Constitution and its subsequent interpretation. There is
absolutely no ambiguity on the status of principles such as
the `right against self-incrimination' and the various
dimensions of `personal liberty'. We have already pointed out
that the rights guaranteed in Articles 20 and 21 of the
Constitution of India have been given a non-derogable status
and they are available to citizens as well as foreigners. It is not
241
within the competence of the judiciary to create exceptions
and limitations on the availability of these rights.
217. Even though the main task of constitutional adjudication
is to safeguard the core organising principles of our polity, we
must also highlight some practical concerns that strengthen
the case against the involuntary administration of the tests in
question. Firstly, the claim that the results obtained from
these techniques will help in extraordinary situations is
questionable. All of the tests in question are those which need
to be patiently administered and the forensic psychologist or
the examiner has to be very skilful and thorough while
interpreting the results. In a narcoanalysis test the subject is
likely to divulge a lot of irrelevant and incoherent information.
The subject is as likely to divulge false information as he/she
is likely to reveal useful facts. Sometimes the revelations may
begin to make sense only when compared with the testimony
of several other individuals or through the discovery of fresh
materials. In a polygraph test, interpreting the results is a
complex process that involves accounting for distortions such
242
as `countermeasures' used by the subject and weather
conditions among others. In a BEAP test, there is always the
possibility of the subject having had prior exposure to the
`probes' that are used as stimuli. All of this is a gradually
unfolding process and it is not appropriate to argue that the
test results will always prove to be crucial in times of exigency.
It is evident that both the tasks of preparing for these tests
and interpreting their results need considerable time and
expertise.
218. Secondly, if we were to permit the forcible administration
of these techniques, it could be the first step on a very
slippery-slope as far as the standards of police behaviour are
concerned. In some of the impugned judgments, it has been
suggested that the promotion of these techniques could reduce
the regrettably high incidence of `third degree methods' that
are being used by policemen all over the country. This is a
circular line of reasoning since one form of improper behaviour
is sought to be replaced by another. What this will result in is
that investigators will increasingly seek reliance on the
243
impugned techniques rather than engaging in a thorough
investigation. The widespread use of `third-degree'
interrogation methods so as to speak is a separate problem
and needs to be tackled through long-term solutions such as
more emphasis on the protection of human rights during
police training, providing adequate resources for investigators
and stronger accountability measures when such abuses do
take place.
219. Thirdly, the claim that the use of these techniques will
only be sought in cases involving heinous offences rings
hollow since there will no principled basis for restricting their
use once the investigators are given the discretion to do so.
From the statistics presented before us as well as the charges
filed against the parties in the impugned judgments, it is
obvious that investigators have sought reliance on the
impugned tests to expedite investigations, unmindful of the
nature of offences involved. In this regard, we do not have the
authority to permit the qualified use of these techniques by
way of enumerating the offences which warrant their use. By
244
itself, permitting such qualified use would amount to a law-
making function which is clearly outside the judicial domain.
220. One of the main functions of constitutionally prescribed
rights is to safeguard the interests of citizens in their
interactions with the government. As the guardians of these
rights, we will be failing in our duty if we permit any citizen to
be forcibly subjected to the tests in question. One could argue
that some of the parties who will benefit from this decision are
hardened criminals who have no regard for societal values.
However, it must be borne in mind that in constitutional
adjudication our concerns are not confined to the facts at
hand but extend to the implications of our decision for the
whole population as well as the future generations. Sometimes
there are apprehensions about judges imposing their personal
sensibilities through broadly worded terms such as
`substantive due process', but in this case our inquiry has
been based on a faithful understanding of principles
entrenched in our Constitution. In this context it would be
useful to refer to some observations made by the Supreme
245
Court of Israel in Public Committee Against Torture in
Israel v. State of Israel, H.C. 5100 / 94 (1999), where it was
held that the use of physical means (such as shaking the
suspect, sleep-deprivation and enforcing uncomfortable
positions for prolonged periods) during interrogation of
terrorism suspects was illegal. Among other questions raised
in that case, it was also held that the `necessity' defence could
be used only as a post factum justification for past conduct
and that it could not be the basis of a blanket pre-emptive
permission for coercive interrogation practices in the future.
Ruling against such methods, Aharon Barak, J. held at p. 26:
"... This is the destiny of democracy, as not all means are
acceptable to it, and not all practices employed by its
enemies are open before it. Although a democracy must
often fight with one hand tied behind its back, it
nonetheless has the upper hand. Preserving the `Rule of
Law' and recognition of an individual's liberty constitutes
an important component in its understanding of
security."
CONCLUSION
221. In our considered opinion, the compulsory administration
of the impugned techniques violates the `right against self-
incrimination'. This is because the underlying rationale of the
246
said right is to ensure the reliability as well as voluntariness of
statements that are admitted as evidence. This Court has
recognised that the protective scope of Article 20(3) extends to
the investigative stage in criminal cases and when read with
Section 161(2) of the Code of Criminal Procedure, 1973 it
protects accused persons, suspects as well as witnesses who
are examined during an investigation. The test results cannot
be admitted in evidence if they have been obtained through
the use of compulsion. Article 20(3) protects an individual's
choice between speaking and remaining silent, irrespective of
whether the subsequent testimony proves to be inculpatory or
exculpatory. Article 20(3) aims to prevent the forcible
`conveyance of personal knowledge that is relevant to the facts
in issue'. The results obtained from each of the impugned tests
bear a `testimonial' character and they cannot be categorised
as material evidence.
222. We are also of the view that forcing an individual to
undergo any of the impugned techniques violates the standard
of `substantive due process' which is required for restraining
247
personal liberty. Such a violation will occur irrespective of
whether these techniques are forcibly administered during the
course of an investigation or for any other purpose since the
test results could also expose a person to adverse
consequences of a non-penal nature. The impugned
techniques cannot be read into the statutory provisions which
enable medical examination during investigation in criminal
cases, i.e. the Explanation to Sections 53, 53-A and 54 of the
Code of Criminal Procedure, 1973. Such an expansive
interpretation is not feasible in light of the rule of `ejusdem
generis' and the considerations which govern the
interpretation of statutes in relation to scientific
advancements. We have also elaborated how the compulsory
administration of any of these techniques is an unjustified
intrusion into the mental privacy of an individual. It would
also amount to `cruel, inhuman or degrading treatment' with
regard to the language of evolving international human rights
norms. Furthermore, placing reliance on the results gathered
from these techniques comes into conflict with the `right to fair
trial'. Invocations of a compelling public interest cannot justify
248
the dilution of constitutional rights such as the `right against
self-incrimination'.
223. In light of these conclusions, we hold that no individual
should be forcibly subjected to any of the techniques in
question, whether in the context of investigation in criminal
cases or otherwise. Doing so would amount to an unwarranted
intrusion into personal liberty. However, we do leave room for
the voluntary administration of the impugned techniques in
the context of criminal justice, provided that certain
safeguards are in place. Even when the subject has given
consent to undergo any of these tests, the test results by
themselves cannot be admitted as evidence because the
subject does not exercise conscious control over the responses
during the administration of the test. However, any
information or material that is subsequently discovered with
the help of voluntary administered test results can be
admitted, in accordance with Section 27 of the Evidence Act,
1872. The National Human Rights Commission had published
`Guidelines for the Administration of Polygraph Test (Lie
249
Detector Test) on an Accused' in 2000. These guidelines should
be strictly adhered to and similar safeguards should be
adopted for conducting the `Narcoanalysis technique' and the
`Brain Electrical Activation Profile' test. The text of these
guidelines has been reproduced below:
(i) No Lie Detector Tests should be administered except
on the basis of consent of the accused. An option
should be given to the accused whether he wishes
to avail such test.
(ii) If the accused volunteers for a Lie Detector Test, he
should be given access to a lawyer and the physical,
emotional and legal implication of such a test
should be explained to him by the police and his
lawyer.
(iii) The consent should be recorded before a Judicial
Magistrate.
(iv) During the hearing before the Magistrate, the
person alleged to have agreed should be duly
represented by a lawyer.
(v) At the hearing, the person in question should also
be told in clear terms that the statement that is
made shall not be a `confessional' statement to the
Magistrate but will have the status of a statement
made to the police.
(vi) The Magistrate shall consider all factors relating to
the detention including the length of detention and
the nature of the interrogation.
(vii) The actual recording of the Lie Detector Test shall
be done by an independent agency (such as a
hospital) and conducted in the presence of a lawyer.
250
(viii) A full medical and factual narration of the manner
of the information received must be taken on
record.
224. The present batch of appeals is disposed of accordingly.
