*442 MR. JUSTICE POWELL delivered the opinion of the Court.
This case presents the question whether the United States Government may compel testimony from an unwilling witness, who invokes the Fifth Amendment privilege against compulsory self-incrimination, by conferring on the witness immunity from use of the compelled testimony in subsequent criminal proceedings, as well as immunity from use of evidence derived from the testimony.
Petitioners were subpoenaed to appear before a United States grand jury in the Central District of California on February 4, 1971. The Government believed that petitioners were likely to assert their Fifth Amendment privilege. Prior to the scheduled appearances, the Government applied to the District Court for an order directing petitioners to answer questions and produce evidence before the grand jury under a grant of immunity conferred pursuant to 18 U. S. C. §§ 6002-6003. Petitioners opposed issuance of the order, contending primarily that the scope of the immunity provided by the statute was not coextensive with the scope of the privilege against self-incrimination, and therefore was not sufficient to supplant the privilege and compel their testimony. The District Court rejected this contention, and ordered petitioners to appear before the grand jury and answer its questions under the grant of immunity.
Petitioners appeared but refused to answer questions, asserting their privilege against compulsory self-incrimination. They were brought before the District Court, and each persisted in his refusal to answer the grand jury's questions, notwithstanding the grant of immunity. The court found both in contempt, and committed them to the custody of the Attorney General until either they answered the grand jury's questions or the term of the grand jury expired.[1] The Court of *443 Appeals for the Ninth Circuit affirmed. Stewart v. United States, 440 F. 2d 954 (CA9 1971). This Court granted certiorari to resolve the important question whether testimony may be compelled by granting immunity from the use of compelled testimony and evidence derived therefrom ("use and derivative use" immunity), or whether it is necessary to grant immunity from prosecution for offenses to which compelled testimony relates ("transactional" immunity). 402 U. S. 971 (1971).
I
The power of government to compel persons to testify in court or before grand juries and other governmental agencies is firmly established in Anglo-American jurisprudence.[2] The power with respect to courts was established by statute in England as early as 1562,[3] and Lord Bacon observed in 1612 that all subjects owed the King their "knowledge and discovery."[4] While it is not clear when grand juries first resorted to compulsory process to secure the attendance and testimony of witnesses, the general common-law principle that "the public has a right to every man's evidence" was considered an "indubitable certainty" that "cannot be denied" by 1742.[5] The power to compel testimony, and the corresponding duty to testify, are recognized in the Sixth Amendment *444 requirements that an accused be confronted with the witnesses against him, and have compulsory process for obtaining witnesses in his favor. The first Congress recognized the testimonial duty in the Judiciary Act of 1789, which provided for compulsory attendance of witnesses in the federal courts.[6] MR. JUSTICE WHITE noted the importance of this essential power of government in his concurring opinion in Murphy v. Waterfront Comm'n, 378 U. S. 52, 93-94 (1964):
"Among the necessary and most important of the powers of the States as well as the Federal Government to assure the effective functioning of government in an ordered society is the broad power to compel residents to testify in court or before grand juries or agencies. See Blair v. United States, 250 U. S. 273. Such testimony constitutes one of the Government's primary sources of information."
But the power to compel testimony is not absolute. There are a number of exemptions from the testimonial duty,[7] the most important of which is the Fifth Amendment privilege against compulsory self-incrimination. The privilege reflects a complex of our fundamental values and aspirations,[8] and marks an important advance in the development of our liberty.[9] It can be asserted in any proceeding, civil or criminal, administrative or judicial, investigatory or adjudicatory;[10] and it *445 protects against any disclosures that the witness reasonably believes could be used in a criminal prosecution or could lead to other evidence that might be so used.[11] This Court has been zealous to safeguard the values that underlie the privilege.[12]
Immunity statutes, which have historical roots deep in Anglo-American jurisprudence,[13] are not incompatible *446 with these values. Rather, they seek a rational accommodation between the imperatives of the privilege and the legitimate demands of government to compel citizens to testify. The existence of these statutes reflects the importance of testimony, and the fact that many offenses are of such a character that the only persons capable of giving useful testimony are those implicated in the crime. Indeed, their origins were in the context of such offenses,[14]*447 and their primary use has been to investigate such offenses.[15] Congress included immunity statutes in many of the regulatory measures adopted in the first half of this century.[16] Indeed, prior to the enactment of the statute under consideration in this case, there were in force over 50 federal immunity statutes.[17] In addition, every State in the Union, as well as the District of Columbia and Puerto Rico, has one or more such statutes.[18] The commentators,[19] and this Court on several occasions,[20] have characterized immunity statutes as essential to the effective enforcement of various criminal statutes. As Mr. Justice Frankfurter observed, speaking for the Court in Ullmann v. United States, 350 U. S. 422 (1956), such statutes have "become part of our constitutional fabric."[21]Id., at 438.
*448 II
Petitioners contend, first, that the Fifth Amendment's privilege against compulsory self-incrimination, which is that "[n]o person . . . shall be compelled in any criminal case to be a witness against himself," deprives Congress of power to enact laws that compel self-incrimination, even if complete immunity from prosecution is granted prior to the compulsion of the incriminatory testimony. In other words, petitioners assert that no immunity statute, however drawn, can afford a lawful basis for compelling incriminatory testimony. They ask us to reconsider and overrule Brown v. Walker, 161 U. S. 591 (1896), and Ullmann v. United States, supra, decisions that uphold the constitutionality of immunity statutes.[22] We find no merit to this contention and reaffirm the decisions in Brown and Ullmann.
III
Petitioners' second contention is that the scope of immunity provided by the federal witness immunity statute, 18 U. S. C. § 6002, is not coextensive with the scope of the Fifth Amendment privilege against compulsory self-incrimination, and therefore is not sufficient to supplant the privilege and compel testimony over a claim of the privilege. The statute provides that when a witness is compelled by district court order to testify over a claim of the privilege:
"the witness may not refuse to comply with the order on the basis of his privilege against self-incrimination; but no testimony or other information compelled under the order (or any information *449 directly or indirectly derived from such testimony or other information) may be used against the witness in any criminal case, except a prosecution for perjury, giving a false statement, or otherwise failing to comply with the order."[23] 18 U. S. C. § 6002.
The constitutional inquiry, rooted in logic and history, as well as in the decisions of this Court, is whether the immunity granted under this statute is coextensive with the scope of the privilege.[24] If so, petitioners' refusals to answer based on the privilege were unjustified, and the judgments of contempt were proper, for the grant of immunity has removed the dangers against which the privilege protects. Brown v. Walker, supra. If, on the other hand, the immunity granted is not as comprehensive as the protection afforded by the privilege, petitioners were justified in refusing to answer, and the judgments of contempt must be vacated. McCarthy v. Arndstein, 266 U. S. 34, 42 (1924).
Petitioners draw a distinction between statutes that provide transactional immunity and those that provide, as does the statute before us, immunity from use and derivative use.[25] They contend that a statute must at a minimum grant full transactional immunity in order to be coextensive with the scope of the privilege. In support of this contention, they rely on Counselman v. Hitchcock, 142 U. S. 547 (1892), the first case in which this Court considered a constitutional challenge to an immunity statute. The statute, a re-enactment of the Immunity Act of 1868,[26] provided that no "evidence obtained from a party or witness by means of a judicial *450 proceeding . . . shall be given in evidence, or in any manner used against him . . . in any court of the United States . . . ."[27] Notwithstanding a grant of immunity and order to testify under the revised 1868 Act, the witness, asserting his privilege against compulsory self-incrimination, refused to testify before a federal grand jury. He was consequently adjudged in contempt of court.[28] On appeal, this Court construed the statute as affording a witness protection only against the use of the specific testimony compelled from him under the grant of immunity. This construction meant that the statute "could not, and would not, prevent the use of his testimony to search out other testimony to be used in evidence against him."[29] Since the revised 1868 Act, as construed by the Court, would permit the use against the immunized witness of evidence derived from his compelled testimony, it did not protect the witness to the same extent that a claim of the privilege would protect him. Accordingly, under the principle that a grant of immunity cannot supplant the privilege, and is not sufficient to compel testimony over a claim of the privilege, unless the scope of the grant of immunity is coextensive with the scope of the privilege,[30] the witness' refusal to testify was held proper. In the course of its opinion, the Court made the following statement, on which petitioners heavily rely:
"We are clearly of opinion that no statute which leaves the party or witness subject to prosecution *451 after he answers the criminating question put to him, can have the effect of supplanting the privilege conferred by the Constitution of the United States. [The immunity statute under consideration] does not supply a complete protection from all the perils against which the constitutional prohibition was designed to guard, and is not a full substitute for that prohibition. In view of the constitutional provision, a statutory enactment, to be valid, must afford absolute immunity against future prosecution for the offence to which the question relates." 142 U. S., at 585-586.
Sixteen days after the Counselman decision, a new immunity bill was introduced by Senator Cullom,[31] who urged that enforcement of the Interstate Commerce Act would be impossible in the absence of an effective immunity statute.[32] The bill, which became the Compulsory Testimony Act of 1893,[33] was drafted specifically to meet the broad language in Counselman set forth above.[34] The new Act removed the privilege against self-incrimination in hearings before the Interstate Commerce Commission and provided that:
"no person shall be prosecuted or subjected to any penalty or forfeiture for or on account of any transaction, matter or thing, concerning which he may testify, or produce evidence, documentary or otherwise. . . ." Act of Feb. 11, 1893, 27 Stat. 444.
*452 This transactional immunity statute became the basic form for the numerous federal immunity statutes[35] until 1970, when, after re-examining applicable constitutional principles and the adequacy of existing law, Congress enacted the statute here under consideration.[36] The new statute, which does not "afford [the] absolute immunity against future prosecution" referred to in Counselman, was drafted to meet what Congress judged to be the conceptual basis of Counselman, as elaborated in subsequent decisions of the Court, namely, that immunity from the *453 use of compelled testimony and evidence derived therefrom is coextensive with the scope of the privilege.[37]
The statute's explicit proscription of the use in any criminal case of "testimony or other information compelled under the order (or any information directly or indirectly derived from such testimony or other information)" is consonant with Fifth Amendment standards. We hold that such immunity from use and derivative use is coextensive with the scope of the privilege against self-incrimination, and therefore is sufficient to compel testimony over a claim of the privilege. While a grant of immunity must afford protection commensurate with that afforded by the privilege, it need not be broader. Transactional immunity, which accords full immunity from prosecution for the offense to which the compelled testimony relates, affords the witness considerably broader protection than does the Fifth Amendment privilege. The privilege has never been construed to mean that one who invokes it cannot subsequently be prosecuted. Its sole concern is to afford protection against being "forced to give testimony leading to the infliction of `penalties affixed to . . . criminal acts.' "[38] Immunity from the use of compelled testimony, as well as evidence derived directly and indirectly therefrom, affords this protection. It prohibits the prosecutorial authorities from using the compelled testimony in any respect, and it therefore insures that the testimony cannot lead to the infliction of criminal penalties on the witness.
Our holding is consistent with the conceptual basis of Counselman. The Counselman statute, as construed by the Court, was plainly deficient in its failure to *454 prohibit the use against the immunized witness of evidence derived from his compelled testimony. The Court repeatedly emphasized this deficiency, noting that the statute:
"could not, and would not, prevent the use of his testimony to search out other testimony to be used in evidence against him or his property, in a criminal proceeding . . ." 142 U. S., at 564;
that it:
"could not prevent the obtaining and the use of witnesses and evidence which should be attributable directly to the testimony he might give under compulsion, and on which he might be convicted, when otherwise, and if he had refused to answer, he could not possibly have been convicted," ibid.;
and that it:
"affords no protection against that use of compelled testimony which consists in gaining therefrom a knowledge of the details of a crime, and of sources of information which may supply other means of convicting the witness or party." 142 U. S., at 586.
The basis of the Court's decision was recognized in Ullmann v. United States, 350 U. S. 422 (1956), in which the Court reiterated that the Counselman statute was insufficient:
"because the immunity granted was incomplete, in that it merely forbade the use of the testimony given and failed to protect a witness from future prosecution based on knowledge and sources of information obtained from the compelled testimony." Id., at 437. (Emphasis supplied.)
See also Arndstein v. McCarthy, 254 U. S. 71, 73 (1920). The broad language in Counselman relied upon by petitioners *455 was unnecessary to the Court's decision, and cannot be considered binding authority.[39]
In Murphy v. Waterfront Comm'n, 378 U. S. 52 (1964), the Court carefully considered immunity from use of compelled testimony and evidence derived therefrom. The Murphy petitioners were subpoenaed to testify at a hearing conducted by the Waterfront Commission of New York Harbor. After refusing to answer certain questions on the ground that the answers might tend to incriminate them, petitioners were granted immunity *456 from prosecution under the laws of New Jersey and New York.[40] They continued to refuse to testify, however, on the ground that their answers might tend to incriminate them under federal law, to which the immunity did not purport to extend. They were adjudged in civil contempt, and that judgment was affirmed by the New Jersey Supreme Court.[41]
The issue before the Court in Murphy was whether New Jersey and New York could compel the witnesses, whom these States had immunized from prosecution under their laws, to give testimony that might then be used to convict them of a federal crime. Since New Jersey and New York had not purported to confer immunity from federal prosecution, the Court was faced with the question what limitations the Fifth Amendment privilege imposed on the prosecutorial powers of the Federal Government, a nonimmunizing sovereign. After undertaking an examination of the policies and purposes of the privilege, the Court overturned the rule that one jurisdiction within our federal structure may compel a witness to give testimony which could be used to convict him of a crime in another jurisdiction.[42] The Court held that the privilege protects state witnesses against incrimination under federal as well as state law, and federal witnesses against incrimination *457 under state as well as federal law. Applying this principle to the state immunity legislation before it, the Court held the constitutional rule to be that:
"[A] state witness may not be compelled to give testimony which may be incriminating under federal law unless the compelled testimony and its fruits cannot be used in any manner by federal officials in connection with a criminal prosecution against him. We conclude, moreover, that in order to implement this constitutional rule and accommodate the interests of the State and Federal Governments in investigating and prosecuting crime, the Federal Government must be prohibited from making any such use of compelled testimony and its fruits."[43] 378 U. S., at 79.
The Court emphasized that this rule left the state witness and the Federal Government, against which the witness had immunity only from the use of the compelled testimony and evidence derived therefrom, "in substantially the same position as if the witness had claimed his privilege in the absence of a state grant of immunity." Ibid.
It is true that in Murphy the Court was not presented with the precise question presented by this case, whether a jurisdiction seeking to compel testimony may do so by granting only use and derivative-use immunity, for New Jersey and New York had granted petitioners transactional immunity. The Court heretofore has not *458 squarely confronted this question,[44] because post-Counselman immunity statutes reaching the Court either have followed the pattern of the 1893 Act in providing transactional immunity,[45] or have been found deficient for failure to prohibit the use of all evidence derived from compelled testimony.[46] But both the reasoning of the Court in Murphy and the result reached compel the conclusion that use and derivative-use immunity is constitutionally sufficient to compel testimony over a claim of the privilege. Since the privilege is fully applicable and its scope is the same whether invoked in a state or in a federal jurisdiction,[47] the Murphy conclusion that a prohibition on use and derivative use secures a witness' Fifth Amendment privilege against infringement by the Federal Government demonstrates that immunity from use and derivative use is coextensive with the scope of the privilege. As the Murphy Court noted, immunity from use and derivative use "leaves the witness and the Federal Government in substantially the same position *459 as if the witness had claimed his privilege"[48] in the absence of a grant of immunity. The Murphy Court was concerned solely with the danger of incrimination under federal law, and held that immunity from use and derivative use was sufficient to displace the danger. This protection coextensive with the privilege is the degree of protection that the Constitution requires, and is all that the Constitution requires even against the jurisdiction compelling testimony by granting immunity.[49]
IV
Although an analysis of prior decisions and the purpose of the Fifth Amendment privilege indicates that use and derivative-use immunity is coextensive with the privilege, we must consider additional arguments advanced by petitioners against the sufficiency of such immunity. We start from the premise, repeatedly affirmed by this Court, that an appropriately broad immunity grant is compatible with the Constitution.
Petitioners argue that use and derivative-use immunity will not adequately protect a witness from various possible incriminating uses of the compelled testimony: for example, the prosecutor or other law enforcement officials may obtain leads, names of witnesses, or other information not otherwise available that might result in a prosecution. It will be difficult and perhaps impossible, the argument goes, to identify, by testimony or cross-examination, the subtle ways in which the compelled testimony may disadvantage a witness, especially in the jurisdiction granting the immunity.
This argument presupposes that the statute's prohibition *460 will prove impossible to enforce. The statute provides a sweeping proscription of any use, direct or indirect, of the compelled testimony and any information derived therefrom:
"[N]o testimony or other information compelled under the order (or any information directly or indirectly derived from such testimony or other information) may be used against the witness in any criminal case . . . ." 18 U. S. C. § 6002.
This total prohibition on use provides a comprehensive safeguard, barring the use of compelled testimony as an "investigatory lead,"[50] and also barring the use of any evidence obtained by focusing investigation on a witness as a result of his compelled disclosures.
A person accorded this immunity under 18 U. S. C. § 6002, and subsequently prosecuted, is not dependent for the preservation of his rights upon the integrity and good faith of the prosecuting authorities. As stated in Murphy:
"Once a defendant demonstrates that he has testified, under a state grant of immunity, to matters related to the federal prosecution, the federal authorities have the burden of showing that their evidence is not tainted by establishing that they had an independent, legitimate source for the disputed evidence." 378 U. S., at 79 n. 18.
This burden of proof, which we reaffirm as appropriate, is not limited to a negation of taint; rather, it imposes on the prosecution the affirmative duty to prove that the evidence it proposes to use is derived from a legitimate source wholly independent of the compelled testimony.
*461 This is very substantial protection,[51] commensurate with that resulting from invoking the privilege itself. The privilege assures that a citizen is not compelled to incriminate himself by his own testimony. It usually operates to allow a citizen to remain silent when asked a question requiring an incriminatory answer. This statute, which operates after a witness has given incriminatory testimony, affords the same protection by assuring that the compelled testimony can in no way lead to the infliction of criminal penalties. The statute, like the Fifth Amendment, grants neither pardon nor amnesty. Both the statute and the Fifth Amendment allow the government to prosecute using evidence from legitimate independent sources.
The statutory proscription is analogous to the Fifth Amendment requirement in cases of coerced confessions.[52] A coerced confession, as revealing of leads as testimony given in exchange for immunity,[53] is inadmissible in a criminal trial, but it does not bar prosecution.[54] Moreover, a defendant against whom incriminating evidence has been obtained through a grant of immunity may be in a stronger position at trial than a defendant who asserts a Fifth Amendment coerced-confession claim. One raising a claim under this statute need only show that he testified under a grant of immunity in order to shift to the government the heavy burden of proving that all of the evidence it proposes to use was derived from *462 legitimate independent sources.[55] On the other hand, a defendant raising a coerced-confession claim under the Fifth Amendment must first prevail in a voluntariness hearing before his confession and evidence derived from it become inadmissible.[56]
There can be no justification in reason or policy for holding that the Constitution requires an amnesty grant where, acting pursuant to statute and accompanying safeguards, testimony is compelled in exchange for immunity from use and derivative use when no such amnesty is required where the government, acting without colorable right, coerces a defendant into incriminating himself.
We conclude that the immunity provided by 18 U. S. C. § 6002 leaves the witness and the prosecutorial authorities in substantially the same position as if the witness had claimed the Fifth Amendment privilege. The immunity therefore is coextensive with the privilege and suffices to supplant it. The judgment of the Court of Appeals for the Ninth Circuit accordingly is
Affirmed.
MR. JUSTICE BRENNAN and MR. JUSTICE REHNQUIST took no part in the consideration or decision of this case.
MR. JUSTICE DOUGLAS, dissenting.
The Self-Incrimination Clause says: "No person . . . shall be compelled in any criminal case to be a witness against himself." I see no answer to the proposition that he is such a witness when only "use" immunity is granted.
My views on the question of the scope of immunity that is necessary to force a witness to give up his guarantee *463 against self-incrimination contained in the Fifth Amendment are so well known, see Ullmann v. United States, 350 U. S. 422, 440 (dissenting), and Piccirillo v. New York, 400 U. S. 548, 549 (dissenting), that I need not write at length.
In Counselman v. Hitchcock, 142 U. S. 547, 586, the Court adopted the transactional immunity test: "In view of the constitutional provision, a statutory enactment, to be valid, must afford absolute immunity against future prosecution for the offense to which the question relates." Id., at 586. In Brown v. Walker, 161 U. S. 591, a case involving another federal prosecution, the immunity statute provided that the witness would be protected "on account of any transaction . . . concerning which he may testify." Id., at 594. The Court held that the immunity offered was coterminous with the privilege and that the witness could therefore be compelled to testify, a ruling that made "transactional immunity" part of the fabric of our constitutional law. Ullmann v. United States, supra, at 438.
This Court, however, apparently believes that Counselman and its progeny were overruled sub silentio in Murphy v. Waterfront Comm'n, 378 U. S. 52. Murphy involved state witnesses, granted transactional immunity under state law, who refused to testify for fear of subsequent federal prosecution. We held that the testimony in question could be compelled, but that the Federal Government would be barred from using any of the testimony, or its fruits, in a subsequent federal prosecution.
Murphy overruled, not Counselman, but Feldman v. United States, 322 U. S. 487, which had held "that one jurisdiction within our federal structure may compel a witness to give testimony which could be used to convict him of a crime in another jurisdiction." Murphy v. Waterfront Comm'n, supra, at 77. But Counselman, *464 as the Murphy Court recognized, "said nothing about the problem of incrimination under the law of another sovereign." Id., at 72. That problem is one of federalism, as to require transactional immunity between jurisdictions might
"deprive a state of the right to prosecute a violation of its criminal law on the basis of another state's grant of immunity [a result which] would be gravely in derogation of its sovereignty and obstructive of its administration of justice." United States ex rel. Catena v. Elias, 449 F. 2d 40, 44 (CA3 1971).
Moreover, as MR. JUSTICE BRENNAN has pointed out, the threat of future prosecution
"substantial when a single jurisdiction both compels incriminating testimony and brings a later prosecution, may fade when the jurisdiction bringing the prosecution differs from the jurisdiction that compelled the testimony. Concern over informal and undetected exchange of information is also correspondingly less when two different jurisdictions are involved." Piccirillo v. New York, 400 U. S., at 568 (dissenting).
None of these factors apply when the threat of prosecution is from the jurisdiction seeking to compel the testimony, which is the situation we faced in Counselman, and which we face today. The irrelevance of Murphy to such a situation was made clear in Albertson v. Subversive Activities Control Board, 382 U. S. 70, in which the Court struck down an immunity statute because it failed to measure up to the standards set forth in Counselman. Inasmuch as no interjurisdictional problems presented themselves, Murphy was not even cited. That is further proof that Murphy was not thought significantly to *465 undercut Counselman.[1] See Stevens v. Marks, 383 U. S. 234, 244-245; id., at 249-250 (Harlan, J., concurring and dissenting); Mansfield, The Albertson Case: Conflict Between the Privilege Against Self-Incrimination and the Government's Need for Information, 1966 Sup. Ct. Rev. 103, 164.
If, as some have thought, the Bill of Rights contained only "counsels of moderation" from which courts and legislatures could deviate according to their conscience or discretion, then today's contraction of the Self-Incrimination Clause of the Fifth Amendment would be understandable. But that has not been true, starting with Chief Justice Marshall's opinion in United States v. Burr, *466 25 F. Cas. 38 (No. 14692e) (CC Va.), where he ruled that the reach of the Fifth Amendment was so broad as to make the privilege applicable when there was a mere possibility of a criminal charge being made.
The Court said in Hale v. Henkel, 201 U. S. 43, 67, that "if the criminality has already been taken away, the Amendment ceases to apply." In other words, the immunity granted is adequate if it operates as a complete pardon for the offense. Brown v. Walker, 161 U. S., at 595. That is the true measure of the Self-Incrimination Clause. As MR. JUSTICE BRENNAN has stated: "[U]se immunity literally misses half the point of the privilege, for it permits the compulsion without removing the criminality." Piccirillo v. New York, supra, at 567 (dissenting).
As MR. JUSTICE BRENNAN has also said:
"Transactional immunity . . . provides the individual with an assurance that he is not testifying about matters for which he may later be prosecuted. No question arises of tracing the use or non-use of information gleaned from the witness' compelled testimony. The sole question presented to a court is whether the subsequent prosecution is related to the substance of the compelled testimony. Both witness and government know precisely where they stand. Respect for law is furthered when the individual knows his position and is not left suspicious that a later prosecution was actually the fruit of his compelled testimony." 400 U. S., at 568-569 (dissenting).
When we allow the prosecution to offer only "use" immunity we allow it to grant far less than it has taken away. For while the precise testimony that is compelled may not be used, leads from that testimony may *467 be pursued and used to convict the witness.[2] My view is that the framers put it beyond the power of Congress to Compel anyone to confess his crimes. The Self-Incrimination Clause creates, as I have said before, "the federally protected right of silence," making it unconstitutional to use a law "to pry open one's lips and make him a witness against himself." Ullmann v. United States, 350 U. S., at 446 (dissenting). That is indeed one of the chief procedural guarantees in our accusatorial system. Government acts in an ignoble way when it stoops to the end which we authorize today.
I would adhere to Counselman v. Hitchcock and hold that this attempt to dilute the Self-Incrimination Clause is unconstitutional.
MR. JUSTICE MARSHALL, dissenting.
Today the Court holds that the United States may compel a witness to give incriminating testimony, and subsequently prosecute him for crimes to which that testimony relates. I cannot believe the Fifth Amendment permits that result. See Piccirillo v. New York, Additional Information
