he offered to take a lietetectc,. test if ore could be arranged. A
test was given bar the American military at the request of the local
public prosecutor, and the results apparently indicated that the

The Supra Gou rt,. although admitting that the first duty of a
court in a criminal proceeding is to dater the truth, held that
the search for the truth must be conducted in acco rdanCe with
established legal principles. The accused is a party to, rather than
the object of# a Criminal proceeding, and he cannot be subjected to
any searches or other limitations which are not provided for by law,

freedom of an accused is based upon principles ct constitutional
law and crix!ri.nel. procedures,, as well as upon the concept that an
individual Is a self-accountable moral personality. Ia ir. ementa
upon this freedom of the will are prohibited regardless of the accuseda's
consent to the violation. it was this right of the accuse d to decide
whether and how to answer every question that the Supra Court held
to be irreconcilable with the application of a lie-detector test.
The reasoning behind the decision is this t During the lie-detector
tests the accused may vol,untariiy give answers to the questions presented;
however, at the same time, his "true" arneweras-and thus the fact of
his "guilt"-...are actually obtained against his will. Such insight
into the soul Of the accused violates his freedom of decision and
action. It must be prohibited in ersmina l proceedings because each
individual has the right to retain an important and ua'enounceable
psychic sphere which in necessary for the maintenance and development
of his personal,itW?
"THE BASIC CONCEPT
"Freedom of the will" is an important concept in Germn criminal
law and procedure. It signifies the notion of hmnan dignity and respect
for hunnn rights. The basic explanation of the individual's relation
to society in that human rights are not regarded as a privilege granted
by society; rather, the individual is an integral part of a social

German ].avya believe that an intbute understa ng of the coMpte
freedom of the will, freedom of the personality and the physical
freedom of the individual is a pre-requisite to ux srstsxzti.ng the
self, Although the law is regarded as an
ever-growir g boo ch des to reflect the intellectual progress
or stagnation of a particular genlration* the concept of a free will
is recognized as a permanent and basic principle of the criminal law.
Apart from the histo ricals philosophical and m tical aspects
sources of the
protection afforded the human pearsonal ty are the Constitution of the
Federal Republic of tans&W and the present Code of Criminal Procedure.
The Constitution guarantees the dignity of the individoarlf the
right to free development of his personality and the physical safety
of his person, and these rights can be listed only as provided by

governed the German legal arywtem prior to 1933s but which was

Both practices were Wised with raterease, to the questions
of whether and to what extoUt the body of the accused could be
utilized to elicit facts wtthl* his knowledge and thsrety ascertain
the truth and arrive at a just vqOAA regarding the can at hand.
The conolusiors reached ooncceurixTg the locality of admiwistaring
truth eerim tests were considered to be equally applicable with
respect to the legali of l so d tictor tests. Both means of
interrogating an accused,, in the opinion of most Owman authorities,
represented illegal attempts to circumvent the right of the accused
not to express himself with respect to the criminal charge.
The advocates of lie-detector testing, on the other hand,
advanced the argwant that such *silent comwdcatiom s" may lawfully
be evaluated as evidence. Their reasoning was that lie-det ctor
recordings are observations of the external appearamses of the accused
which are noticeable in a m e exact form than whe* the accused is
observed without an instrumental aid. Section 81a of the Code, which
authorizes an oxamin. tion of the body of the accused to establish
facts which are relevant to the p eedinsgs, was cited as the Iegal
basis for lie-detector tests am when the accused objects to the
test, Since the questiom1mg during the tout was thought not to
impair the accused$s faraedcm to act according to his am vi. i,
Sections 136 and 136. of the Code wrote not viewed as prohibitions
against lie-detector tests.

argmeent that the recordings disclose the otherwise concealed psychic
structure of the accused and that they are an actual attempt to
discover what might be present only in the unconsciousness of the
accused. XWA authorities adopted this latter view and disapproved
of any nethod of obtaining e'essions which are not noticeable to
the a iner himself. under Ws views the lie-detector disclosure of
secret physiological reactions, followed by the exeminor's evaluations
becomes the equivalent of an involuntary com> cation. And obtain
ceeeenunications regardless of whether the accused is willing to make
them violates his right to decide whether he wants to answer the
criminal charge. The opponents of lie-detector tooting have several
grounds for refutiz the not that the tests are authorised under
Section 81a of the Code as an "examination of the body of the accused."
Thus, one group argued that the intent of the legislature in
enacting section 81a was to allow only proof of the physical condition
of the body of the accused Anothd group argued that section 136a
controls to prohibit the use of lie-detector tests inasmuch as the
perobibitions of that section were meant to be illustrative of unlawful
practices rather than an all inclusive listing. A third group opposing
the use of lie-detector tests argued that even if sections 136 and 136aa,
were not directly controlling? the application of Ito-detector tests
would be prohibited by the fundamental principles of criminal law which
recognise the right of an aodused to remain silent without fear of
thereby incurring legal disadvantages.
The prevailing view which considers the use of lie4detector tests
to be unlawful is in h orU with Article One of the Federal Coxastitu.

880 TULANE LAW REVIEW [Vol. XXXIII
public expense, 12 the Uniform Act appears to be constitutionally
sound. It benefits from a device entitling witnesses to a hearing
before the forwarding judge, which procedure seems adequate to
prevent unreasonable and abusive application. The strength of the
Uniform Act lies in its effective means of securing material evi-
dence from unwilling and evasive witnesses who would otherwise
be unavailable. The interests of justice are best served when the
complete truth is before the court. EDGAR H. DRUM
EVIDENCE - ADMISSIBILITY OF LIE DETECTOR EVIDENCE - At
the trial in which defendant was convicted of second degree mur-
der, the prosecution's witness, a police officer, testified that he had
informed the defendant during pre-trial investigation that a lie
detector test indicated he was lying. The trial court granted de-
fendant's motion to strike the testimony and instructed the jury
to disregard it. The District Court of Appeal held that insertion
of lie detector evidence in a criminal proceeding is not prejudice
constituting reversible error if the trial judge has given the jury
proper instructions to disregard the evidence. People v. Schiers,
324 P.2d 981 (Cal. App. 1958). A petition to the California Su-
preme Court was denied per curiam with three dissents. People v.
Schiers, 320 P.2d 1 (Cal. 1958).
Since the first reported case on the subject in 1923, results of

of the Uniform Act and require witnesses to attend and testify. However, the
Uniform Act being indefinite on the point, the same courts have held that
the statute does not authorize courts to procure the attendance of witnesses
for the defendant at the expense of the public. The defendant must apparently
pay these expenses himself. Vore v. State, 158 Neb. 222, 63 N.W.2d 141

lie detector tests have generally been excluded from evidence. The
exclusion, which applies to civil as well as criminal cases,' is based
on the theory that the lie detector has not gained sufficient scien-
tific recognition to warrant acceptance of the tests as competent
legal evidence 2 In civil cases admission of such evidence is im-
proper, but usually does not constitute reversible error. In criminal
cases, however, admission, whether urged by state or defendant,"
constitutes reversible error which cannot be corrected by an ad-
monition to the jury to disregard the testimony." This rule obtains
whether the evidence relates to results of," or conversations about,
lie detector tests which indicate that the accused was lying.? Al-
though People v. Houser' made an exception to the general exclu-
sionary rule by admitting such evidence if the parties have stipu-
lated that test results should be admissible on behalf of either
prosecution or defense, the exception is apparently recognized in
only a minority of jurisdictions." No other exceptions are made to
admit lie detector evidence.""

Although the District Court of Appeal held that jurors are pre-
sumed to heed a strong admonition, which dissipates the harm
done by admission of lie detector evidence,1' the dissent by the
three California Supreme Court justices points out that "This case
breaks the uniformity of California decisions holding that an ad-
monition to ignore the prosecution's evidence of lie detector tests
is powerless."12 The case is important because it departs from
both California and predominant national precedent."
Evidence admitted at trial is not regarded as completely re-
liable. It must be weighed by the trier of fact. Although the lie
detector is not 100% accurate, there is authority to support the
view that it is just as efficient and accurate as some presently
accepted methods of determining facts.14 The principal lie detector
in use is the polygraph.'-' Some polygraph examiners claim that
results obtained by diagnostic processes are almost 95%fo accurate."
Taking into consideration the inadequate examiner, however, some
authorities have estimated that the percentage of error may be as
high as 25%.17 The presence of determinable inaccuracies has not,

(where conviction rested on circumstantial evidence, admission of evidence
that defendant refused to take lie detector test was prejudicial error). Com-
pare Tyler v. United States, 193 F.2d 24 (D.C. Cir. 1951), where defendant's
confession following the test and a statement which the examiner made to
defendant that the lie detector indicated defendant was lying were both ad-
mitted. The trial court instructed the jury that the evidence was not admitted
to show defendant was lying, but merely as bearing upon the question whether
the confession was in fact voluntary. The appellate court affirmed the con-
viction: "With the court's clear and positive instruction to the jury, holding
the evidence within proper bounds, and the presumption that the instruction
was followed by the jury, we are not warranted in assuming that any prejudi-
cial results followed from the incident." Id. at 31. It is contended, however,
that limiting instructions in general have a negligible effect. See, e.g., Frank-
furter, Law and Politics 167 (1939); Comment, 8 Stan. L. Rev. 451, 456

The examiners were unable to arrive at a definite opinion in four per cent of
the cases. See Inbau & Reid, Lie Detection and Criminal Interrogation 111-12

however, prevented appeals to the courts for the admission of test
results in evidence."Although many legal writers continue to
agree with the exclusion of such evidence because of possible inac-
curacies,19 some maintain that the force of the objection is lessened
when it is pointed out that the evidence would not be conclusive
proof when admitted. The fallacy in this contention is that as lie
detectors become more accurate, the trier of fact is more likely to
be influenced by what it may come to consider a mechanically in-
fallible result.20
Previous cases have not considered objections other than lack
of scientific recognition ;21 but that does not mean that other objec-
tions do not exist. The dissent in the principal case concluded that
results of lie detector tests were within the privilege against self-
incrimination granted by the California Constitution.22 To bring
the results within the privilege, such tests would have to be classed
as testimonial because the privilege extends only to testimonial
evidence.23 Although experts have argued that lie detector recorda-
tions do not constitute testimonial utterances,24 the dissent in the
noted case disagreed. It might be argued that examinees who vol-
untarily consent to the test waive the constitutional privilege
against self-incrimination.25 Some even contend that a compulsory
test would not violate the privilege 211
The dissent in the instant case also apparently presents the
first judicial consideration of excluding such evidence for lack of

Dean Wicker urges the courts to re-examine the statement originating in the
Frye case that the lie detector has not gained such standing and scientific
recognition as to justify the admission of its results, because that statement
was made at a time when the lie detector was in its infancy.

due process. It is possible that lack of due process could prohibit
admissibility of lie detector evidence under both the fifth and four-
teenth amendments. This objection has been suggested as the
strongest ground for excluding results of such tests 2T
The hearsay rule would perhaps have provided another ground
for excluding the lie detector evidence in the instant case. The
testimony by the prosecution's witness related to an out-of-court
statement used to prove the fact asserted.28 It would not come with-
in the admissions exception because it was not a statement made
by the defendant 28 Furthermore, the prosecution should be
estopped from arguing that the test results were admissions be-
cause admissions are definitely testimonial. Such an argument
might lend efficacy to the self-incrimination objection.
EVIDENCE - ADVERSE SPOUSAL TESTIMONY IN FEDERAL COURTS
- Defendant was convicted of a violation of the Mann Act for
transporting a girl from Arkansas to Oklahoma for immoral pur-
poses. Defendant's wife appeared voluntarily as a government wit-
ness and, over his objection, was permitted to testify. The convic-
tion was upheld by the United States Court of Appeals and the
United States Supreme Court granted certiorari. Held, that both
common law precedent and the public interest in promoting do-
mestic harmony preclude admission of testimony by one spouse
against the other even when the witness spouse wishes to testify.
Hawkins v. United States, 358 U.S. 74 (1958).1
At common law neither husband nor wife could appear as a wit-
ness for or against the other in any civil or criminal action.2 On
27Silving, supra note 19.
28"Hearsay evidence is testimony in court or written evidence, of a state-
ment made out of court, such statement being offered as an asertion to show
the truth of matters asserted therein, and thus resting for its value upon the
credibility of the out-of-court asserter." McCormick, Evidence ? 226 (1954).
29"Admissions are the words or acts of a party-opponent, or of his predeces-
sor or representative, offered as evidence against him." Id., ? 239.
iJustice Stewart concurred with the majority on the issues presented, but
indicated that he might have dissented had different arguments been used.
The government argued that the privilege against adverse spousal testimony
should vest in the witness and not the defendant, and that the wife, though
she could not be compelled to do so, could voluntarily testify against her hus-
band. The record indicated, however, that her testimony was not wholly vol.
untary since she had been imprisoned and released on $3000 bond conditioned
upon her appearance as a witness for the United States.
