CERTIORARI,
post, p. 539, to review the affirmance of
convictions in the District Court under an indictment for frauds on
revenue.
Page 308 U. S. 339
MR. JUSTICE FRANKFURTER delivered the opinion of the Court.
We are called upon for the second time to review affirmance by
the Circuit Court of Appeals for the Second Circuit of petitioners'
convictions under an indictment for frauds on the revenue. In
Nardone v. United States, 302 U.
S. 379, this Court reversed the convictions on the first
trial because they were procured by evidence secured in violation
of § 605 of the Communications Act of 1934 (c. 652, 48 Stat.
1064, 1103; 47 U.S.C. § 605). For details of the facts
reference is made to that case. Suffice it here to say that this
evidence consisted of intercepted telephone messages, constituting
"a vital part of the prosecution's proof."
Conviction followed a new trial, and "the main question" on the
appeal below is the only question open here -- namely, "whether the
[trial] judge improperly refused to allow the accused to examine
the prosecution as to the uses to which it had put the information"
which
Nardone v. United States, supra, found to have
vitiated the original conviction. Though candidly doubtful of the
result it reached, the Circuit Court of Appeals limited the scope
of § 605 to the precise circumstances before this Court in the
first
Nardone case, and ruled that
"Congress had not also made incompetent testimony which had
become accessible by the use of unlawful 'taps,' for to divulge
that information was not to divulge an intercepted telephone
talk."
106 F.2d 41.
The issue thus tendered by the Circuit Court of Appeals is the
broad one whether or no § 605 merely interdicts the
introduction into evidence in a federal trial of intercepted
telephone conversations, leaving the prosecution free to make every
other use of the proscribed evidence. Plainly, this presents a
far-reaching problem in
Page 308 U. S. 340
the administration of federal criminal justice, and we therefore
brought the case here for disposition.
Any claim for the exclusion of evidence logically relevant in
criminal prosecutions is heavily handicapped. It must be justified
by an overriding public policy expressed in the Constitution or the
law of the land. In a problem such as that before us now, two
opposing concerns must be harmonized: on the one hand, the stern
enforcement of the criminal law; on the other, protection of that
realm of privacy left free by Constitution and laws but capable of
infringement either through zeal or design. In accommodating both
these concerns, meaning must be given to what Congress has written,
even if not in explicit language, so as to effectuate the policy
which Congress has formulated.
We are here dealing with specific prohibition of particular
methods in obtaining evidence. The result of the holding below is
to reduce the scope of § 605 to exclusion of the exact words
heard through forbidden interceptions, allowing these interceptions
every derivative use that they may serve. Such a reading of §
605 would largely stultify the policy which compelled our decision
in
Nardone v. United States, supra. That decision was not
the product of a merely meticulous reading of technical language.
It was the translation into practicality of broad considerations of
morality and public wellbeing. This Court found that the logically
relevant proof which Congress had outlawed, it outlawed because
"inconsistent with ethical standards and destructive of personal
liberty."
302 U. S. 302 U.S.
379,
302 U. S. 383.
To forbid the direct use of methods thus characterized, but to put
no curb on their full indirect use, would only invite the very
methods deemed "inconsistent with ethical standards and destructive
of personal liberty." What was said in a different context in
Silverthorne Lumber Co. v. United States, 251 U.
S. 385,
251 U. S. 392,
is pertinent here:
"The essence of a provision
Page 308 U. S. 341
forbidding the acquisition of evidence in a certain way is that
not merely evidence so acquired shall not be used before the court,
but that it shall not be used at all."
See Gouled v. United States, 255 U.
S. 298,
255 U. S. 307.
A decent respect for the policy of Congress must save us from
imputing to it a self-defeating, if not disingenuous, purpose.
Here, as in the
Silverthorne case, the facts improperly
obtained do not
"become sacred and inaccessible. If knowledge of them is gained
from an independent source, they may be proved like any others, but
the knowledge gained by the Government's own wrong cannot be used
by it"
simply because it is used derivatively.
251 U.
S. 385,
251 U. S.
392.
In practice, this generalized statement may conceal concrete
complexities. Sophisticated argument may prove a causal connection
between information obtained through illicit wiretapping and the
Government's proof. As a matter of good sense, however, such
connection may have become so attenuated as to dissipate the taint.
A sensible way of dealing with such a situation -- fair to the
intendment of 605, but fair also to the purposes of the criminal
law -- ought to be within the reach of experienced trial judges.
The burden is, of course, on the accused in the first instance to
prove to the trial court's satisfaction that wiretapping was
unlawfully employed. Once that is established -- as was plainly
done here -- the trial judge must give opportunity, however closely
confined, to the accused to prove that a substantial portion of the
case against him was a fruit of the poisonous tree. This leaves
ample opportunity to the Government to convince the trial court
that its proof had an independent origin.
Dispatch in the trial of criminal causes is essential in
bringing crime to book. Therefore, timely steps must be taken to
secure judicial determination of claims of illegality on the part
of agents of the Government in obtaining
Page 308 U. S. 342
testimony. To interrupt the course of the trial for such
auxiliary inquiries impedes the momentum of the main proceeding and
breaks the continuity of the jury's attention. Like mischief would
result were tenuous claims sufficient to justify the trial court's
indulgence of inquiry into the legitimacy of evidence in the
Government's possession. So to read a Congressional prohibition
against the availability of certain evidence would be to
subordinate the need for rigorous administration of justice to
undue solicitude for potential and, it is to be hoped, abnormal
disobedience of the law by the law's officers. Therefore, claims
that taint attaches to any portion of the Government's case must
satisfy the trial court with their solidity, and not be merely a
means of eliciting what is in the Government's possession before
its submission to the jury. And if such a claim is made after the
trial is under way, the judge must likewise be satisfied that the
accused could not at an earlier stage have had adequate knowledge
to make his claim. The civilized conduct of criminal trials cannot
be confined within mechanical rules. It necessarily demands the
authority of limited direction entrusted to the judge presiding in
federal trials, including a well established range of judicial
discretion, subject to appropriate review on appeal, in ruling upon
preliminary questions of fact. Such a system as ours must, within
the limits here indicated, rely on the learning, good sense,
fairness and courage of federal trial judges.
We have dealt with this case on the basic issue tendered by the
Circuit Court of Appeals, and have not indulged in a finicking
appraisal of the record, either as to the issue of the time limit
of the proposed inquiry into the use to which the Government had
put its illicit practices or as to the existence of independent
sources for the Government's proof. Since the Circuit Court of
Appeals did
Page 308 U. S. 343
not question its timeliness, we shall not. And the hostility of
the trial court to the whole scope of the inquiry reflected his own
accord with the rule of law by which the Circuit Court of Appeals
sustained him, and which we find erroneous.
The judgment must be reversed and remanded to the District Court
for further proceedings in conformity with this opinion.
Reversed.
MR. JUSTICE McREYNOLDS is of opinion that the Circuit Court of
Appeals reached the proper conclusion upon reasons there adequately
stated, and its judgment should be affirmed.
MR. JUSTICE REED took no part in the consideration or decision
of this case.
