Mr. Justice Marshall
announced the judgment of the Court and an opinion in which Mr. Justice Douglas and Mr. Justice Stewart join.
Petitioner alleges that Negroes were, systematically excluded from the grand jury that indicted him and the petit jury that convicted him of burglary in the Superior Court of Muscogee County, Georgia. In consequence he contends that his conviction is invalid under the Due Process and Equal Protection Clauses of the Fourteenth Amendment. Because he is not himself a Negro, the respondent contends that he has hot suffered any unconstitutional discrimination, and that his conviction' must stand. ' On that ground, the Court of Appeals affirmed the denial of his petition for federal habeas corpus. 441 •F. 2d 370' (CA5 1971). We granted certiorari. 404 U. S. 964 (1971). We reverse.
I
At the- outset, we reject the contention that the only-issue before this Court is petitioner’s challenge to the composition of the grand jury that indicted him. The respondent argues that the challenge to the petit jury is not before us, because it fails to appear in the list of questions presented by the petition for certiorari. We do not regard that omission as controlling, however, in light of the fact that the two claims have been treated together at every stage of the proceedings below, they are treated together in the body of the petition for certiorari, and they are treated together in the brief filed by petitioner on. the merits in this Court. Petitioner cannot fairly be said to have abandoned his challenge to the petit jury, and the State has had ample opportunity to respond to that challenge, having done so at length below.
Moreover, in this case the principles governing the two claims are identical. First, it appears that the same selection process was used for both the grand jury and the petit jury. Consequently, the question whether jurors were in fact excluded on the basis of race will be answered the same way for both tribunals. Second, both the grand jury and the petit jury in this case must be measured solely by the general Fourteenth Amendment guarantees of due process and equal protection, and not by the specific constitutional provisions for the grand' jury and the petit jury. For the Fifth Amendment right to a grand jury does not apply in a state prosecution. Hurtado v. California, 110 IT. S. 516 (1884). And the Sixth Amendment right to a petit jury, made applicable to the States through the Due Process Clause of the Fourteenth Amendment in Duncan v. Louisiana, 391 U. S. 145 (1968), does not apply to state trials that took place before the decision in Duncan, as petitioner’s trial did. DeStefano v. Woods, 392 U.S. 631 (1968). Accordingly, we turn now to the commands of equal protection and of due process.
II
This Court has never before considered a white defendant’s challenge to the exclusion of Negroes from jury service. The essence of petitioner’s claim is this: that the tribunals that indicted and convicted him were constituted in a manner that is prohibited by the Constitution and by statute; that the impact of that error on any individual trial is unascertainable; and that consequently any indictment or conviction returned by such tribunals must be set aside.
There can be no doubt that, if petitioner’s allegations are true, both tribunals involved in this case were illegally constituted. He alleges that Negroes were systematically excluded from both the grand jury and the petit jury. This Court has repeatedly held that the Constitution prohibits such selection practices, with respect to the grand jury, the petit jury, or both. Moreover, Congress has made it a crime for a public official to exclude anyone from a grand or petit jury on the basis óf race, 18 U. S. C. § 243, and this Court upheld the statute, approving the congressional determination that such exclusion would violate the express prohibitions of the Equal Protection Clause. Ex parte Virginia, 100 U. S. 339 (1880). The crime, and the unconstitutional state action, occur whether the- defendant is white or Negro, whether he is acquitted or convicted. In short, when a grand or petit jury has been selected on an impermissible basis, the existence of a constitutional violation does not depend on the circumstances of the person making the claim.
It is a separate question, however, whether petitioner is entitled to the relief he seeks on the basis of that constitutional violation. Respondent argues that even if the grand and petit juries were unconstitutionally selected, petitioner is not entitled to relief on that account because he has not shown how he was harmed by the error. It is argued that a Negro defendant’s right to challenge the exclusion of Negroes from jury service rests on a presumption that a jury so constituted will be prejudiced against him; that no such presumption is available to a white defendant; and consequently that a white defendant must introduce. affirmative evidence of actual harm in order to establish a basis for relief.
That argument takes too narrow a view of the kinds of harm that flow from discrimination in jury selection. The exclusion of Negroes from jury service, like the arbitrary exclusion of any other well-defined class of citizens, offends a number of related constitutional values.
In Strauder v. West Virginia, 100 U. S. 303, 308-309 (1880), this Court considered the question from the point of view of the Negro defendant’s right to equal protection of the laws. Btrauder was part of a landmark trilogy oí cases, in which this Court first dealt with the problem of racial discrimination in jury selection. In Strauder itself, a Negro defendant sought to remove his criminal trial to the federal. courts, pursuant to statute, on the. ground that Negroes were excluded by law from the grand and petit juries in .the state courts; the Court upheld his claim. In Virginia v. Rives, 100 U. S. 313 (1880), a Negro defendant sought removal on the ground that there were in fact no Negroes in the venire from which his jury was drawn; the Court held that, without more, his claim did not come within the precise terms of the removal statute. Finally, in Ex parte Virginia, 100 U. S. 330 (1880), a state judge challenged the' statute under which he was convicted for the federal crime of excluding Negroes from state grand and petit juries; the Court upheld the statute as a valid means of enforcing the Equal Protection Clause. Because each of these three cases was amenable to decision on the narrow basis of an analysis of the Negro defendant’s right to equal protection, the Court brought all three under that single analytical umbrella.
But even in 1880 the Court recognized that other constitutional values were implicated. In Btrauder, the Court observed that the exclusion of Negroes from jury service injures not only defendants, but also other members of the excluded class: it denies the class of potential jurors the “privilege of participating equally '. . . in the administration of justice,” 100 U. S., at 308, and it stigmatizes the whole class, even those who . do not wish to participate, by declaring them unfit for jury service and thereby putting “a-brand upon them, affixed by law, an assertion of their inferiority.” Ibid. It is now clear that injunctive relief is available to vindicate these interests of the excluded jurors and the stigmatized class. Carter v. Jury Commission of Greene County, 396 U. S. 320 (1970); Turner v. Fouche, 396 U. S. 346 (1970); White v. Crook, 251 F. Supp. 401 (MD Ala. 1966).
Moreover, the Court has also. recognizecLthat the exclusion of a discernible class from jury service injures not only those defendants who belong to the excluded, class, but other defendants as well, in that it destroys the possibility that the jury will reflect a representative cross section of the community. In Williams v. Florida, 399 U. S. 78 (1970), we sought to delineate some of the essential features of the jury that is guaranteed, in certain circumstances, by the Sixth Amendment. We concluded that it comprehends; inter alia, “a fair possibility for obtaining a representative cross-section of the community.” 399 U. S., at 100. Thus if the Sixth Amendment were applicable here, and petitioner were challenging a pqst-Duncan petit jury, he would clearly have standing to challenge the systematic exclusion of any identifiable group from jury service.
The precise question in this case, then, is whether a State may subject a defendant to indictment and trial by grand and petit juries that are plainly illegal in their composition, and leave the defendant without recourse on the ground that he had in any event no right to a grand or petit jury at all. We conclude, for reasons that follow, that to do so denies the defendant due process of law.
Ill
“A fair trial in a fair tribunal is a basic requirement of due process.” In re Murchison, 349 U. S. 133, 136 (1955). The due process right to a competent and impartial tribunal is quite separate from the right to any particular form of proceeding. Due process requires a competent and impartial tribunal in administrative hearings, Goldberg v. Kelly, 397 U. S. 254, 271 (1970), and in trials to a judge, Tumey v. Ohio, 273 U. S. 510 (1927). Similarly, if a State chooses, quite apart from constitutional compulsion, to use a grand or petit jury, due process imposes limitations on the composition of that Jury-
Long before this Court held that the Constitution imposes the requirement of jury trial on the States, it was well established that the Due Process Clause protects a defendant from jurors who are actually incapable of rendering an impartial verdict, based on the evidence and the law. Thus a defendant cannot, consistent with due process, be subjected to trial by an insane juror, Jordan v. Massachusetts, 225 U. S. 167, 176 (1912), by jurors who are intimidated by the threat of mob violence, Moore v. Dempsey, 261 U. S. 86 (1923), or by jurors who have formed a fixed opinion about the case from newspaper publicity, Irvin v. Dowd, 366 U. S. 717 (1961).
Moreover, even if there is no showing of actual bias in the tribunal, this Court has held that due process is denied by circumstances that create the likelihood or the appearance of bias. This rule, too, was well established long before the right to jury trial was made applicable in state trial's, and does not depend on it. Thus it has been invoked in trials to a judge, e. g., Tumey v. Ohio, 273 U. S. 510 (1927); In re Murchison, 349 U. S. 133 (1955); Mayberry v. Pennsylvania, 400 U. S. 455 (1971); and in pre-Duncan state jury trials, e. g., Turner v. Louisiana, 379 U. S. 466 (1965); Estes v. Texas, 381 U. S. 532, 550 (1965). In Tumey v. Ohio, supra, this Court held that a judge could not, consistent with due process, try a case when he had a financial stake in the outcome, notwithstanding the possibility that he might resist the temptation to be influenced by that interest. And in Turner v. Louisiana, supra, the Court held that a jury could not, consistent with due process, try a case after it had been placed in the protective custody of the principal prosecution witnesses, notwithstanding the possibility that the jurors might not be influenced by the association. , As this Court said in In re Murchison, supra, “[f] airness of course requires an absence of actual' bias in the trial of cases. But our system of law has always endeavored to prevent even the probability of unfairness.” 349 U. S., at 136.
These principles compel the conclusion that a State cannot, consistent with due process, subject a defendant to indictment or trial by a jury that has been selected in an arbitrary and discriminatory manner, in violation of the Constitution and laws of the United States. Illegal and unconstitutional jury selection procedures cast doubt on the integrity of the whole judicial process. They create' the appearance of bias in the decision of j individual cases, and they increase the risk of actual ¡ bias as well.
If it were possible to say with confidence that the risk of bias resulting from the arbitrary action involved here is confined to cases involving Negro defendants, then perhaps the right to challenge the tribunal on . that ground could be similarly confined. The case of the white defendant might then be thought to present a species of" harmless error.
But the exclusion from jury service of a substantial and identifiable class of citizens has a potential impact.that is too subtle and too pervasive to admit of confinement to particular issues or particular cases. First, if we assume that the exclusion of Negroes affects the fairness of the jury only with respect to issues presenting a clear opportunity for the operation of- race prejudice, that assumption does not provide a workable guide for decision in particular cases. For the opportunity to appeal to race prejudice is latent in a vast range of issues, cutting across the entire fabric of our society.
Moreover, we are unwilling to make the assumption Ji that the exclusion of Negroes has relevance only for j j issues involving race. When any large and identifiable1 segment of the community is excluded from jury service, the effect is to remove from the jury room qualities of human nature and varieties of human experience, the range of which is unknown and perhaps unknowable. It is not necessary to assume that the excluded group will consistently vote as a class in order to conclude, as we do, that its exclusion deprives the jury of a perspective on human events that may have unsuspected importance, in any case that may be presented.
It is in the nature of the practices here challenged that proof of actual harm, or. lack of harm, is virtually impossible to adduce. For there is no way to determine what jury would have been selected under a constitutionally valid selection system, or how that jury would have decided the case. Consequently, it is necessary to decide on principle which side shall suffer the consequences of unavoidable uncertainty. See Speiser v. Randall, 357 U. S. 513, 525-526 (1958); In re Winship, 397 U. S. 358, 370-373 (1970) (Harlan, J., concurring). In light of the great potential for harm latent in an unconstitutional jury-selection system, and the strong interest of the criminal defendant in avoiding that harm, any doubt should be resolved in favor of giving the opportunity for challenging the jury to too many defendants, rather than giving it to too few.
■ Accordingly, we hold that, whatever his race, a criminal ¡defendant has standing to challenge the systein used to select his grand or petit jury, on the ground that it Arbitrarily excludes from service the members of any race, and thereby denies him due process of law. This certainly is true in this case, where the claim is that Negroes were systematically excluded from jury service. For Congress has made such exclusion a crime. 18 U. S. C. § 243.
IV
Having resolvfed the question of standing, we turn briefly to the further disposition of this case. There is, of course, no question here of justifying the .system under attack. For whatever may be the law with regard to other exclusions from jury service, it is clear beyond all doubt that the exclusion of Negroes cannot pass constitutional muster. Accordingly, if petitioner’s allegations are correct, and Negroes were systematically excluded from his grand and petit juries, then he was indicted, and convicted by tribunals that fail to satisfy the elementary requirements of due process, and neither the indictment nor the conviction can stand. Since he was precluded from proving the facts alleged in support of his claim, the judgment must be reversed and the case remanded for further proceedings consistent with this opinion.
Reversed and remanded.
The history of this litigation is long and- complicated. Petitioner was indicted on June 6, 1966. His first trial resulted in a conviction that was reversed on Fourth Amendment grounds, 114 Ga. App. 595, 152 S. E. 2d 647 (1966). A second trial, held on December 8, 1966, resulted in the conviction challenged here, which was affirmed, 115 Ga. App. 743, 156 S. E. 2d 195 (1967). Petitioner for the first time raised the claim of discriminatory jury selection in a petition for federal habeas corpus, which was summarily denied on July 5, 1967. The Court of Appeals affirmed on the ground that petitioner had failed to exhaust then-available state remedies with respect to his otherwise highly col-orable claim, 397 F. 2d 731, 735-741 (CA5 1968). Petitioner then filed a second petition for federal habeas corpus on the same ground, alleging that intervening state court decisions clearly foreclosed his claim in the state courts. That petition was denied on the grounds (1) that it was repetitious, (2) that petitioner had failed to exhaust, and (3) that his claims were lacking in merit. App. 15. The Court of Appeals again affirmed, rejecting the first two grounds and resting entirely on the third, i. e., rejecting petitioner’s substantive claims. 441 F. 2d 370 (1971). The exhaustion point thus having been resolved in petitioner’s favor below, the State quite properly does not press it here.
See Brief for Appellee in Court of Appeals 28-43.
The jury lists were made up from the tax digests, which were by law segregated according to race; moreover, the jury lists contained a proportion of Negroes much smaller than the proportion in the population or intthe tax digests.- The jury-selection system of Muscogee County, Georgia, was explored in detail and struck down as unconstitutional in Vanleeward v. Rutledge, 369 F. 2d 584 (CA5 1966), contemporaneously with petitioner’s trial. On petitioner’s first federal appeal, the Court of Appeals suggested, though it did not hold, that the Vanleeward findings and conclusions oh this point ihould be regarded as conclusive with respect to Peters, and thereby the expense and delay of a full evidentiary hearing might be avoided, 397 F. 2d, at 740.
A number of state courts and lower federal courts have imposed a “same class” rule on challenges to discriminatory jury selection, holding that the exclusion of a class from jury service is subject to challenge only by a member of the excluded class. Only a few courts have rejected the rule; e. g., Allen v. State, 110 Ga. App. 56, 137 S. E. 2d 711 (1964) (not followed by other panels of same court); State v. Madison, 240 Md. 265, 213 A. 2d 880 (1965). The cases are collected, and criticized, in Note, The Defendant’s Challenge to a Racial Criterion in Jury Selection, 74 Yale L. J. 919 (1965). See also Note, The Congress, The Court and Jury Selection; 52 Va. L. Rev. 1069 (1966); This Court avoided passing on the "same class” rule in Fay v. New York, 332 U. S. 261, 289-290 (1947), and has never since then approved or rejected it.
He also claims his own rights under the Equal Protection Clause have been violated, a claim we need not consider in light of our disposition.

S. 463 (1947); Hale v. Kentucky, 303 U. S. 613 (1938); Norris v. Alabama, 294 U. S. 587 (1935); Martin v. Texas, 200 U. S. 316 (1906); Neal v. Delaware, 103 U. S. 370 (1881); Strauder v. West Virginia, 100 U. S. 303 (1880).
The principle of the representative jury was first articulated by this Court as a requirement of equal protection, in cases vindicating the right of a Negro defendant to challenge the systematic exclusion of Negroes from his grand and petit juries. E. g., Smith v. Texas, 311 U. S. 128, 130 (1940). Subsequently, in the exercise of its supervisory power over federal courts, this Court extended the principle, to permit any defendant to challenge the arbitrary exclusion from jury service of his own or any other class. E. g., Glasser v. United States, 315 U. S. 60, 83-87 (1942); Thiel v. Southern, Pacific Co., 328 U. S. 217, 220 (1946); Ballard v. United States, 329 U. S. 187 (1946). Finally it emerged as an aspect of the constitutional right to jury trial in Williams v. Florida, 399 U. S. 78, 100 (1970).
It is of course a separate question whether his challenge would prevail, i. e., whether the exclusion might be found to have sufficient justification. . See Rawlins v. Georgia, 201 U. S. 638, 640 (1906), holding that' a State may exclude certain occupational categories from jury service “on the bona fide ground that it [is] , for the good of the community that their regular work should not be interrupted.” We have no occasion here to consider what interests might justify an exclusion, or what standard should be applied, since the only question in this case is not the validity of an exclusion but simply standing to challenge it.
Or the class may be expanded slightly to include white civil rights workers, see Allen v. State, 110 Ga. App. 56, 62, 137 S. E. 2d 711, 715 (1964) (alternative holding).
In rejecting, for the federal courts, the exclusion of women from jury service, this Court made the following observations, which are equally relevant to the exclusion of other discernible groups:
“The truth is that the two sexes are not fungible; a community made up exclusively of one is different from a community composed of both; the subtle interplay of influence one on the other is among the imponderables. To insulate the courtroom from either may not in a given case make an iota of difference. Yet a flavor, a distinct quality is lost if either sex is excluded.” Ballard v. United States, 329 U. S. 187, 193-194 (1946) (footnote omitted).
Hill v. Texas, 316 U. S. 400, 406 (1942).
