We granted certiorari to decide whether and, if so, under what circumstances, a prosecutor may elicit testimony from a mental health professional concerning the content of an interview conducted to explore the possibility of presenting psychiatric defenses at trial. We also agreed to review the Court of Appeals' determination that any error in the admission of the psychiatrist's evidence in this case was irrelevant under the holding of Zant v. Stephens, 462 U.S. 862, 103 S.Ct. 2733, 77 L.Ed.2d 235 (1983).

On examination, however, we conclude that petitioner defaulted his underlying constitutional claim by failing to press it before the Supreme Court of Virginia on direct appeal. Accordingly, we decline to address the merits of petitioner's claims and affirm the judgment dismissing the petition for a writ of habeas corpus.

* Following a jury trial, petitioner was convicted of the May 1977 murder of Audrey Weiler. According to his confession, petitioner encountered Ms. Weiler in a secluded area near his home and raped her at knifepoint. Fearing that her testimony could send him back to prison, he then grabbed her by the neck and choked her until she fell unconscious. When he realized that she was still alive, he dragged her into a nearby river, submerged her head, and repeatedly stabbed her with his knife. A subsequent medical examination indicated that the death was attributable to three clusters of lethal injuries: asphyxia from strangulation, drowning, and multiple stab wounds.

Prior to the trial, petitioner's appointed counsel, David Pugh, had explored the possibility of presenting a number of psychiatric defenses. Towards that end, Mr. Pugh requested that the trial court appoint a private psychiatrist, Dr. Wendell Pile, to conduct an examination of petitioner. Aware that psychiatric reports were routinely forwarded to the court and that such reports were then admissible under Virginia law, Mr. Pugh had advised petitioner not to discuss any prior criminal episodes with anyone. App. 134. See Gibson v. Commonwealth, 216 Va. 412, 219 S.E.2d 845 (1975).

Although that general advice was intended to apply to the forthcoming psychiatric examination, Mr. Pugh later testified that he "did not specifically tell [petitioner] not to say anything to Doctor Pile about the offense or any offenses." App. 132. During the course of the examination, Dr. Pile did in fact ask petitioner both about the murder and about prior incidents of deviant sexual conduct. Tr. of State Habeas Hearing 19.

Although petitioner initially declined to answer, he later stated that he had once torn the clothes off a girl on a school bus before deciding not to carry out his original plan to rape her. App. 44. That information, together with a tentative diagnosis of "Sociopathic Personality; Sexual Deviation (rape)," was forwarded to the trial court, with copies sent both to Mr. Pugh and to the prosecutor who was trying the case for the Commonwealth. Id., at 43-45. At no point prior to or during the interview did Dr. Pile inform petitioner that his statements might later be used against him or that he had the right to remain silent and to have counsel present if he so desired. Id., at 90. Cf. Estelle v. Smith, 451 U.S. 454, 101 S.Ct. 1866, 68 L.Ed.2d 359 (1981).

At the sentencing phase of the trial, the Commonwealth called Dr. Pile to the stand. Over the defense's objection, Dr. Pile described the incident on the school bus. Tr. 934-935. On cross-examination, he repeated his earlier conclusion that petitioner was a "sociopathic personality." Id., at 936.

After examining a second psychiatrist, the Commonwealth introduced petitioner's criminal record into evidence. It revealed that he had been convicted of rape in 1973 and had been paroled from the penitentiary on that charge less than four months prior to raping and murdering Ms. Weiler. The defense then called 14 character witnesses, who testified that petitioner had been a regular churchgoer, a member of the choir, a conscientious student in high school, and a good soldier in Vietnam. After lengthy deliberation, the jury recommended that petitioner be sentenced to death.

Petitioner appealed his conviction and sentence to the Supreme Court of Virginia. In his brief he raised 13 separate claims, including a broad challenge to the constitutionality of Virginia's death penalty provisions, objections to several of the trial court's evidentiary rulings, and a challenge to the exclusion of a prospective juror during voir dire. Petitioner did not, however, assign any error concerning the admission of Dr. Pile's testimony.

At a subsequent state postconviction hearing, Mr. Pugh explained that he had consciously decided not to pursue that claim after determining that "Virginia case law would [not] support our position at that particular time." App. 143. Various objections to the Commonwealth's use of Dr. Pile's testimony were raised, however, in a brief filed by amicus curiae Post-Conviction Assistance Project of the University of Virginia Law School.

The Supreme Court of Virginia affirmed the conviction and sentence in all respects. Smith v. Commonwealth, 219 Va. 455, 248 S.E.2d 135 (1978). In a footnote, it noted that, pursuant to a rule of the court, it had considered only those arguments advanced by amicus that concerned errors specifically assigned by the defendant himself. Id., at 460, n. 1, 248 S.E.2d, at 139, n. 1. Accordingly, it did not address any issues concerning the prosecution's use of the psychiatric testimony. This Court denied the subsequent petition for certiorari, which, again, did not urge the claim that admission of Dr. Pile's testimony violated petitioner's rights under the Federal Constitution. 441 U.S. 967, 99 S.Ct. 2419, 60 L.Ed.2d 1074 (1979).

In 1979, petitioner sought a writ of habeas corpus in the Circuit Court for the City of Williamsburg and the County of James City. For the first time since the trial, he argued that the admission of Dr. Pile's testimony violated his privilege against self-incrimination under the Fifth and Fourteenth Amendments to the Federal Constitution.

The court ruled, however, that petitioner had forfeited the claim by failing to press it in earlier proceedings. At a subsequent evidentiary hearing, conducted solely on the issue of ineffective assistance of counsel, the court heard testimony concerning the reasons underlying Mr. Pugh's decision not to pursue the Fifth Amendment claim on appeal. On the basis of that testimony, the court found that Pugh and his assistant had researched the question, but had determined that the claim was unlikely to succeed.

Thus, the court found, "counsel exercised reasonable judgment in deciding not to preserve the objection on appeal, and . . . this decision resulted from informed, professional deliberation." App. to Pet. for Cert. 71. Petitioner appealed the denial of his habeas petition to the Supreme Court of Virginia, contending that the Circuit Court had erred in finding that his objection to the admission of Dr. Pile's testimony had been defaulted. The Supreme Court declined to accept the appeal, Smith v. Morris, 221 Va. cxliii (1981), and we again denied certiorari. 454 U.S. 1128, 102 S.Ct. 981, 71 L.Ed.2d 117 (1981).

Having exhausted state remedies, petitioner sought a writ of habeas corpus in the United States District Court for the Eastern District of Virginia. In an unpublished order, the court denied the petition, holding that the objection to the admission of Dr. Pile's testimony was "clearly barred" under this Court's decision in Wainwright v. Sykes, 433 U.S. 72, 97 S.Ct. 2497, 53 L.Ed.2d 594 (1977). App. 158. In reaching that conclusion, the District Judge noted that "the default resulted not from the trial attorney's ignorance or inadvertence, but because of a deliberate tactical decision." Ibid.

The Court of Appeals for the Fourth Circuit affirmed, but on different grounds. Smith v. Procunier, 769 F.2d 170 (1985). Finding it unnecessary to rely on procedural default or to address the merits of the substantive constitutional claim, the court held that admission of Dr. Pile's testimony, even if erroneous, could not be the basis for invalidating petitioner's sentence. It noted that the jury had relied on two distinct aggravating factors in its decision to recommend the death penalty. The psychiatric testimony, however, only bore on one of those factors, the likelihood that petitioner would "constitute a continuing serious threat to society." Va.Code § 19.2-264.2 (1983); Tr. 1102.

In that circumstance, the Court of Appeals believed, our decision in Zant v. Stephens, 462 U.S., at 884, 103 S.Ct., at 2746, 77 L.Ed.2d 235, required the conclusion that the error, if any, was irrelevant to the overall validity of the sentence. We granted certiorari, Smith v. Sielaff, 474 U.S. 918, 106 S.Ct. 245, 88 L.Ed.2d 254 (1985), and now affirm on the authority of our decision in Murray v. Carrier, 477 U.S. 478, 106 S.Ct. 2639, 91 L.Ed.2d 397 (1986).

Under Virginia law, failure to raise a claim on direct appeal from a criminal conviction ordinarily bars consideration of that claim in any subsequent state proceeding. See, e.g., Coppola v. Warden of Virginia State Penitentiary, 222 Va. 369, 282 S.E.2d 10 (1981); Slayton v. Parrigan, 215 Va. 27, 205 S.E.2d 680 (1974). In the present case, the Virginia courts have enforced that rule by declining to consider petitioner's objection to the admission of Dr. Pile's testimony, a claim concededly not included in his initial appeal from his conviction and sentence. Consistent with our earlier intimations in Reed v. Ross, 468 U.S. 1, 11, 104 S.Ct. 2901, 2907-2908, 82 L.Ed.2d 1 (1984), we held in Murray v. Carrier, 477 U.S. 478, 106 S.Ct. 2639, 91 L.Ed.2d 397, that a federal habeas court must evaluate appellate defaults under the same standards that apply when a defendant fails to preserve a claim at trial.

Accordingly, although federal courts at all times retain the power to look beyond state procedural forfeitures, the exercise of that power ordinarily is inappropriate unless the defendant succeeds in showing both "cause" for noncompliance with the state rule and "actual prejudice resulting from the alleged constitutional violation." Wainwright v. Sykes, supra, 433 U.S., at 84, 97 S.Ct., at 2505; Murray v. Carrier, 477 U.S., at 485, 106 S.Ct., at ----. As we explained more fully in Carrier, this congruence between the standards for appellate and trial default reflects our judgment that concerns for finality and comity are virtually identical regardless of the timing of the defendant's failure to comply with legitimate state rules of procedure.

We need not determine whether petitioner has carried his burden of showing actual prejudice from the allegedly improper admission of Dr. Pile's testimony, for we think it self-evident that he has failed to demonstrate cause for his noncompliance with Virginia's procedures. We have declined in the past to essay a comprehensive catalog of the circumstances that would justify a finding of cause. Reed v. Ross, supra, 468 U.S., at 13, 104 S.Ct., at 2909; see also Wainwright v. Sykes, supra, 433 U.S., at 91, 97 S.Ct., at 2508. Our cases, however, leave no doubt that a deliberate, tactical decision not to pursue a particular claim is the very antithesis of the kind of circumstance that would warrant excusing a defendant's failure to adhere to a State's legitimate rules for the fair and orderly disposition of its criminal cases. As the Court explained in Reed:

"[D]efense counsel may not make a tactical decision to forgo a procedural opportunity—for instance, to object at trial or to raise an issue on appeal—and then when he discovers that the tactic has been unsuccessful, pursue an alternative strategy in federal court. The encouragement of such conduct by a federal court on habeas corpus review would not only offend generally accepted principles of comity, but would undermine the accuracy and efficiency of the state judicial systems to the detriment of all concerned. Procedural defaults of this nature are, therefore, inexcusable, and cannot qualify as 'cause' for purposes of federal habeas corpus review." 468 U.S., at 14, 104 S.Ct., at 2909 (internal quotation and citation omitted).

Here the record unambiguously reveals that petitioner's counsel objected to the admission of Dr. Pile's testimony at trial and then consciously elected not to pursue that claim before the Supreme Court of Virginia. The basis for that decision was counsel's perception that the claim had little chance of success in the Virginia courts. With the benefit of hindsight, petitioner's counsel in this Court now contends that this perception proved to be incorrect. Cf. Gibson v. Zahradnick, 581 F.2d 75 (CA4 1978) (repudiating reasoning of Gibson v. Commonwealth, 216 Va. 412, 219 S.E.2d 845 (1975)).

Even assuming that to be the case, however, a State's subsequent acceptance of an argument deliberately abandoned on direct appeal is irrelevant to the question whether the default should be excused on federal habeas. Indeed, it is the very prospect that a state court "may decide, upon reflection, that the contention is valid" that undergirds the established rule that "perceived futility alone cannot constitute cause," Engle v. Isaac, 456 U.S. 107, 130, and n. 36, 102 S.Ct. 1558, 1573 and 36, 71 L.Ed.2d 783 (1982); for "[a]llowing criminal defendants to deprive the state courts of [the] opportunity" to reconsider previously rejected constitutional claims is fundamentally at odds with the principles of comity that animate Sykes and its progeny. Id., at 130, 102 S.Ct., at 1573.

Notwithstanding the deliberate nature of the decision not to pursue his objection to Dr. Pile's testimony on appeal—a course of conduct virtually dispositive of any effort to satisfy Syke 's "cause" requirement—petitioner contends that the default should be excused because Mr. Pugh's decision, though deliberate, was made in ignorance. Had he investigated the claim more fully, petitioner maintains, "it is inconceivable that he would have concluded that the claim was without merit or that he would have failed to raise it." Reply Brief for Petitioner 3.

The argument is squarely foreclosed by our decision in Carrier, which holds that "the mere fact that counsel failed to recognize the factual or legal basis for a claim, or failed to raise the claim despite recognizing it, does not constitute cause for a procedural default." Supra, 477 U.S., at 486-487, 106 S.Ct., at 2641. See also Engle v. Isaac, supra, 456 U.S., at 133-134, 102 S.Ct., at 1574-75. Nor can it seriously be maintained that the decision not to press the claim on appeal was an error of such magnitude that it rendered counsel's performance constitutionally deficient under the test of Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984). Carrier reaffirmed that "the right to effective assistance of counsel . . . may in a particular case be violated by even an isolated error . . . if that error is sufficiently egregious and prejudicial." Supra, 477 U.S., at 496, 106 S.Ct., at 2650; see also United States v. Cronic, 466 U.S. 648, 657, n. 20, 104 S.Ct. 2039, 2046 n. 20, 80 L.Ed.2d 657 (1984).

But counsel's deliberate decision not to pursue his objection to the admission of Dr. Pile's testimony falls far short of meeting that rigorous standard. After conducting a vigorous defense at both the guilt and sentencing phases of the trial, counsel surveyed the extensive transcript, researched a number of claims, and decided that, under the current state of the law, 13 were worth pursuing on direct appeal. This process of "winnowing out weaker arguments on appeal and focusing on" those more likely to prevail, far from being evidence of incompetence, is the hallmark of effective appellate advocacy. Jones v. Barnes, 463 U.S. 745, 751-752, 103 S.Ct. 3308, 3312-3313, 77 L.Ed.2d 987 (1983).

It will often be the case that even the most informed counsel will fail to anticipate a state appellate court's willingness to reconsider a prior holding or will underestimate the likelihood that a federal habeas court will repudiate an established state rule. But, as Strickland v. Washington made clear, "[a] fair assessment of attorney performance requires that every effort be made to eliminate the distorting effects of hindsight, to reconstruct the circumstances of counsel's challenged conduct, and to evaluate the conduct from counsel's perspective at the time." 466 U.S., at 689, 104 S.Ct., at 2065. Viewed in light of Virginia law at the time Mr. Pugh submitted his opening brief to the Supreme Court of Virginia, the decision not to pursue his objection to the admission of Dr. Pile's testimony fell well within the "wide range of professionally competent assistance" required under the Sixth Amendment to the Federal Constitution. Id., at 690, 104 S.Ct., at 2066.

Nor can petitioner rely on the novelty of his legal claim as "cause" for noncompliance with Virginia's rules. See Reed v. Ross, 468 U.S., at 18, 104 S.Ct., at 2911 ("[W]here a constitutional claim is so novel that its legal basis is not reasonably available to counsel, a defendant has cause for his failure to raise the claim in accordance with applicable state procedures"). Petitioner contends that this Court's decisions in Estelle v. Smith, 451 U.S. 454, 101 S.Ct. 1866, 68 L.Ed.2d 359 (1981), and Ake v. Oklahoma, 470 U.S. 68, 105 S.Ct. 1087, 84 L.Ed.2d 53 (1985), which were decided well after the affirmance of his conviction and sentence on direct appeal, lend support to his position that Dr. Pile's testimony should have been excluded.

But, as a comparison of Reed and Engle makes plain, the question is not whether subsequent legal developments have made counsel's task easier, but whether at the time of the default the claim was "available" at all. As petitioner has candidly conceded, various forms of the claim he now advances had been percolating in the lower courts for years at the time of his original appeal. Brief for Petitioner 20-21, n. 12; Reply Brief for Petitioner 3.

Moreover, in this very case, an amicus before the Supreme Court of Virginia specifically argued that admission of Dr. Pile's testimony violated petitioner's rights under the Fifth and Sixth Amendments. Brief for Post-Conviction Assistance Project of the University of Virginia Law School as Amicus Curiae in No. 780293, pp. 53-62. Under these circumstances, it simply is not open to argument that the legal basis of the claim petitioner now presses on federal habeas was unavailable to counsel at the time of the direct appeal.

We conclude, therefore, that petitioner has not carried his burden of showing cause for noncompliance with Virginia's rules of procedure. That determination, however, does not end our inquiry. As we noted in Engle and reaffirmed in Carrier, " '[i]n appropriate cases' the principles of comity and finality that inform the concepts of cause and prejudice 'must yield to the imperative of correcting a fundamentally unjust incarceration.' " Murray v. Carrier, supra, 477 U.S., at 495, 106 S.Ct., at 2654, quoting Engle v. Isaac, supra, 456 U.S., at 135. Accordingly, "where a constitutional violation has probably resulted in the conviction of one who is actually innocent, a federal habeas court may grant the writ even in the absence of a showing of cause for the procedural default." Murray v. Carrier, supra, 477 U.S., at 496, 106 S.Ct., at 2650.

We acknowledge that the concept of "actual," as distinct from "legal," innocence does not translate easily into the context of an alleged error at the sentencing phase of a trial on a capital offense. Nonetheless, we think it clear on this record that application of the cause and prejudice test will not result in a "fundamental miscarriage of justice." Engle, 456 U.S., at 135, 102 S.Ct., at 1576.

There is no allegation that the testimony about the school bus incident was false or in any way misleading. Nor can it be argued that the prospect that Dr. Pile might later testify against him had the effect of foreclosing meaningful exploration of psychiatric defenses. While that concern is a very real one in the abstract, here the record clearly shows that Dr. Pile did ask petitioner to discuss the crime he stood accused of committing as well as prior incidents of deviant sexual conduct. Although initially reluctant to do so, ultimately petitioner was forthcoming on both subjects.

In short, the alleged constitutional error neither precluded the development of true facts nor resulted in the admission of false ones. Thus, even assuming that, as a legal matter, Dr. Pile's testimony should not have been presented to the jury, its admission did not serve to pervert the jury's deliberations concerning the ultimate question whether in fact petitioner constituted a continuing threat to society. Under these circumstances, we do not believe that refusal to consider the defaulted claim on federal habeas carries with it the risk of a manifest miscarriage of justice.

Nor can we concur in Justice STEVENS' suggestion that we displace established procedural default principles with an amorphous "fundamental fairness" inquiry. Post, at 542-543. Precisely which parts of the Constitution are "fundamental" and which are not is left for future elaboration. But, for Justice STEVENS, when a defendant in a capital case raises a "substantial, colorable" constitutional claim, a federal court should entertain it no matter how egregious the violation of state procedural rules, and regardless of the fairness of the opportunity to raise that claim in the course of his trial and appeal. Post, at 546.

We reject the suggestion that the principles of Wainwright v. Sykes apply differently depending on the nature of the penalty a State imposes for the violation of its criminal laws. We similarly reject the suggestion that there is anything "fundamentally unfair" about enforcing procedural default rules in cases devoid of any substantial claim that the alleged error undermined the accuracy of the guilt or sentencing determination.

In view of the profound societal costs that attend the exercise of habeas jurisdiction, such exercise "carries a serious burden of justification." H. Friendly, Is Innocence Irrelevant? Collateral Attack on Criminal Judgments, 38 U.Chi.L.Rev. 142, 146 (1970); see also Engle v. Isaac, supra, 456 U.S., at 126-129, 102 S.Ct., at 1571-1572. When the alleged error is unrelated to innocence, and when the defendant was represented by competent counsel, had a full and fair opportunity to press his claim in the state system, and yet failed to do so in violation of a legitimate rule of procedure, that burden has not been carried.

Accordingly, we affirm the judgment of the Court of Appeals upholding the dismissal of petitioner's application for a writ of habeas corpus.

Affirmed.

[For dissenting opinion of Justice BRENNAN, see post, p. 2678.]

Justice STEVENS, with whom Justice MARSHALL and Justice BLACKMUN join and with whom Justice BRENNAN joins as to Parts II and III, dissenting.

The record in this case unquestionably demonstrates that petitioner's constitutional claim is meritorious, and that there is a significant risk that he will be put to death because his constitutional rights were violated.

The Court does not take issue with this conclusion. It is willing to assume that (1) petitioner's Fifth Amendment right against compelled self-incrimination was violated; (2) his Eighth Amendment right to a fair, constitutionally sound sentencing proceeding was violated by the introduction of the evidence from that Fifth Amendment violation; and (3) those constitutional violations made the difference between life and death in the jury's consideration of his fate.

Although the constitutional violations and issues were sufficiently serious that this Court decided to grant certiorari, and although the Court of Appeals for the Fourth Circuit decided the issue on the merits, this Court concludes that petitioner's presumably meritorious constitutional claim is procedurally barred and that petitioner must therefore be executed.

In my opinion, the Court should reach the merits of petitioner's argument. To the extent that there has been a procedural "default," it is exceedingly minor—perhaps a kind of "harmless" error. Petitioner's counsel raised a timely objection to the introduction of the evidence obtained in violation of the Fifth Amendment. A respected friend of the Court—the University of Virginia Law School's Post-Conviction Assistance Project brought the issue to the attention of the Virginia Supreme Court in an extensive amicus curiae brief. Smith's counsel also raised the issue in state and federal habeas corpus proceedings, and, as noted, the Court of Appeals decided the case on the merits. Consistent with the well-established principle that appellate arguments should be carefully winnowed,1 however, Smith's counsel did not raise the Fifth Amendment issue in his original appeal to the Virginia Supreme Court—an unsurprising decision in view of the fact that a governing Virginia Supreme Court precedent, which was then entirely valid and only two years old, decisively barred the claim.2

Nevertheless, the Court finds the lawyer's decision not to include the constitutional claim "virtually dispositive." Ante, at 535. The Court offers the remarkable explanation that "[u]nder these circumstances"—in which petitioner's death penalty will stand despite serious Fifth and Eighth Amendment violations that played a critical role in the determination that death is an appropriate penalty—"we do not believe that refusal to consider the defaulted claim on federal habeas carries with it the risk of a manifest miscarriage of justice." Ante, at 538.

I fear that the Court has lost its way in a procedural maze of its own creation and that it has grossly misevaluated the requirements of "law and justice" that are the federal court's statutory mission under the federal habeas corpus statute.3 To understand the nature of the Court's error, it is necessary to assess the Court's conclusion that the claim is procedurally defaulted; to consider the Fifth Amendment violation; and to consider the Eighth Amendment violation.

* We begin with the common ground. The historic office of the Great Writ as the ultimate protection against fundamental unfairness is well known.4 That mission is reflected in the statutory requirement that the federal court "dispose of the matter as law and justice require." 28 U.S.C. § 2243. It is by now equally clear that the application of the Court's "cause and prejudice" formulation as a rigid bar to review of fundamental constitutional violations has no support in the statute, or in Federal Rule of Criminal Procedure 12(b)(2), from which it was initially imported;5 the standard thus represents judicial lawmaking of the most unabashed form.

The Court nonetheless reaffirms today, as it has consistently held in the past,6 that federal courts retain the power to entertain federal habeas corpus requests despite the absence of "cause and prejudice," ante, at 537; the only question is whether to exercise that power.

Despite the rigor of its cause-and-prejudice standard, moreover, the Court continues to commit itself to maintaining the availability of habeas corpus under certain circumstances, even in the absence of "cause," ibid; indeed, this Term, the Court has emphasized the importance of that availability by remanding a case to consider the merits of a prisoner's claim even though the prisoner failed to show "cause" for the default. Murray v. Carrier, 477 U.S. 478, 106 S.Ct. 2639, 91 L.Ed.2d 397 (1986).

The Court concludes in this case that no miscarriage of justice will result from a refusal to entertain Smith's challenge to his death sentence. This conclusion is flawed in three respects. First, the Court mistakenly assumes that only a claim implicating "actual innocence" rises to the level of a miscarriage of justice. Second, the Court does not properly assess the force of a claim that a death penalty is invalid. Finally, the Court vastly exaggerates the state interest in refusing to entertain this claim.

The Court accurately quotes the holding in Murray v. Carrier: " '[W]here a constitutional violation has probably resulted in the conviction of one who is actually innocent, a federal habeas court may grant the writ even in the absence of a showing of cause for the procedural default.' " Supra, at 537, 106 S.Ct., at 2650. The Court then seeks to transfer this "actual innocence" standard to capital sentencing proceedings, and concludes that, in petitioner's sentencing hearing, "the alleged constitutional error neither precluded the development of true facts nor resulted in the admission of false ones." Ibid.

The Court does not explain, however, why Carrier's clearly correct holding about the propriety of the writ in a case of innocence must also be a limiting principle on the federal court's ability to exercise its statutory authority to entertain federal habeas corpus actions; more specifically, the Court does not explain why the same principle should not apply when a constitutional violation is claimed to have resulted in a lack of fundamental fairness, either in a conviction or in a death sentence.

This analysis is far removed from the traditional understanding of habeas corpus. For instance, in Moore v. Dempsey, 261 U.S. 86, 43 S.Ct. 265, 67 L.Ed. 543 (1923), the Court considered a claim that the murder convictions and death sentences of five black defendants were unconstitutional.

The Federal District Court had dismissed the writ of habeas corpus. In his opinion for the Court, Justice Holmes explained that in view of the allegations—systematic exclusion of blacks from the jury and threatened mob violence—the Federal District Court should not have dismissed the writ without considering the factual allegations. The Court noted the presence of a clear procedural default—the Arkansas Supreme Court had refused to entertain the challenge to discrimination in the jury because the objection "came too late." Id., at 91, 43 S.Ct., at 266, 267. The Court nevertheless held that the Federal District Court should have entertained the petition. Id., at 92, 43 S.Ct., at 267.

Although the allegations clearly implicated questions about the accuracy of the truth-finding process, the Court's opinion cannot be fairly read to rest on the kind of "innocence" inquiry that the Court propounds today. For the Court specifically rejected the notion that its inquiry into the presence of a serious constitutional violation was actually an inquiry into the guilt or innocence of the petitioners: "The petitioners say that [the victim] must have been killed by other whites [rather than by the black petitioners], but that we leave on one side as what we have to deal with is not the petitioners' innocence or guilt but solely the question whether their constitutional rights have been preserved." Id., at 87-88, 43 S.Ct., at 265 (emphasis added). Today, the Court adopts the converse of Justice Holmes' proposition: it leaves to one side the question whether constitutional rights have been preserved, and considers only petitioner's innocence or guilt.7

The majority's reformulation of the traditional understanding of habeas corpus appears to be premised on the notion that only constitutional violations which go to guilt or innocence are sufficiently serious to implicate the "fundamental fairness" alluded to in Engle v. Isaac, 456 U.S. 107, 126, 102 S.Ct. 1558, 1571, 71 L.Ed.2d 783 (1982).8

If accuracy in the determination of guilt or innocence were the only value of our criminal justice system, then the Court's analysis might have a great deal of force. If accuracy is the only value, however, then many of our constitutional protections—such as the Fifth Amendment right against compelled self-incrimination and the Eighth Amendment right against cruel and unusual punishment, the very claims asserted by petitioner—are not only irrelevant, but possibly counterproductive.9

Our Constitution, however, and our decision to adopt an "accusatorial," rather than an "inquisitorial" system of justice,10 reflect a different choice. That choice is to afford the individual certain protections—the right against compelled self-incrimination and the right against cruel and unusual punishment among them—even if those rights do not necessarily implicate the accuracy of the truth-finding proceedings. Rather, those protections are an aspect of the fundamental fairness, liberty, and individual dignity that our society affords to all, even those charged with heinous crimes.

In my opinion, then, the Court's exaltation of accuracy as the only characteristic of "fundamental fairness" is deeply flawed. Our criminal justice system, and our Constitution, protect other values in addition to the reliability of the guilt or innocence determination, and the statutory duty to serve "law and justice" should similarly reflect those values.

Thus, the Court begins with a conception of "fundamental fairness" that is far too narrow and that conflicts with the nature of our criminal justice system. The Court similarly fails to give appropriate weight to the fact that capital punishment is at stake in this case. It is now well settled that "death is a different kind of punishment from any other which may be imposed in this country." Gardner v. Florida, 430 U.S. 349, 357, 97 S.Ct. 1197, 1204, 51 L.Ed.2d 393 (1977) (STEVENS, J.).11

It is of vital importance to the defendant and to the community that any decision to impose the death sentence be, and appear to be, the consequence of scrupulously fair procedures. When a condemned prisoner raises a substantial, colorable Eighth Amendment violation, there is a special obligation, consistent with the statutory mission to "dispose of the matter as law and justice require," to consider whether the prisoner's claim would render his sentencing proceeding fundamentally unfair.

Indeed, it was precisely this concern that prompted the Court of Appeals to consider petitioner's argument on the merits: "[W]e give weight to the consideration that we have before us a matter of life and death. The imminent execution of Smith serves as sufficient grounds to review the issue." Smith v. Procunier, 769 F.2d 170, 172 (1985).

Finally, as in every habeas corpus decision, the magnitude of the State's interest must be considered. In this case, several factors suggest that the State's interest is not adequate to obstruct federal habeas corpus consideration of petitioner's claim. First, petitioner made a timely objection at trial, and the state interest in enforcing procedural default rules at trial is far greater than the State's interest in enforcing procedural default rules on appeal.12

Second, the issue was raised before the state court in an amicus curiae brief.13 Since this is a matter on which courts ordinarily may exercise discretion,14 the discretionary decision not to address the issue hardly rises to a state interest of sufficient magnitude that a man should die even though his Fifth and Eighth Amendment rights were violated to achieve that objective.

Third, the issue was presented to the state courts in state habeas proceedings—after the precedent blocking petitioner's claim had been repudiated15—and the state habeas court, while finding that the decision by Smith's counsel not to raise the issue with a governing Virginia precedent squarely against him was entirely reasonable,16 concluded that the Fifth Amendment claim was procedurally barred and thus did not address it.17

Fourth, the Court of Appeals for the Fourth Circuit addressed the merits and did not rest on any notion of procedural default; this Court customarily defers to federal courts of appeals on questions of state law,18 including questions about "cause" for failure to comply with state procedural rules.19 Finally, and most importantly, the inadequacy of the state interest in this death penalty context is decisively shown by the prevailing practice in many States that appellate courts have a special duty in capital cases to overlook procedural defaults and review the trial record for reversible error, before affirming that most severe of all sentences.20

Thus, the Court is mistaken in its narrow definition of fundamental fairness, in its failure to appreciate the significance of a challenge to a death penalty, and in its exaggeration of the State's interest in refusing to entertain a claim that was raised at trial, on appeal by an amicus, and in state habeas proceedings; that was addressed on the merits by the Court of Appeals (and briefed and argued on the merits in this Court); and that must be assumed to make the difference between life and death. Because I disagree with the Court's evaluation of these matters, I would address the merits of petitioner's argument that constitutional violations render his sentence of death fundamentally unfair.

The introduction of petitioner's comments to the court-appointed psychiatrist clearly violated the Fifth Amendment. As the majority points out, psychiatric reports by court-appointed psychiatrists "were routinely forwarded to the court and . . . were then admissible under Virginia law." Ante, at 529. However, "[a]t no point prior to or during the interview did Dr. Pile inform petitioner that his statements might later be used against him or that he had the right to remain silent and to have counsel present if he so desired." Ibid.

Moreover, the court-appointed psychiatrist related petitioner's description of an earlier sexual assault in a letter to the court and to the prosecution, as well as to the defense, and testified about the description, at the State's request, at petitioner's capital sentencing hearing. The State thus relied on Dr. Pile's testimony as evidence of "future dangerousness," one of the two aggravating circumstances found by the jury to justify a sentence of death.21

Chief Justice BURGER's opinion for the Court in Estelle v. Smith, 451 U.S. 454, 101 S.Ct. 1866, 68 L.Ed.2d 359 (1981), makes it absolutely clear that the introduction of this evidence by the prosecution at the sentencing stage violated the Fifth Amendment. As THE CHIEF JUSTICE explained, the Fifth Amendment fully applies to a capital sentencing proceeding: "Just as the Fifth Amendment prevents a criminal defendant from being made ' "the deluded instrument of his own conviction," ' Culombe v. Connecticut, 367 U.S. [568,] 581, 81 S.Ct. 1860, 1867, 6 L.Ed.2d 1037, quoting 2 W. Hawkins, Pleas of the Crown 595 (8th ed. 1824), it protects him as well from being made 'the deluded instrument' of his own execution." Id., 451 U.S., at 462, 101 S.Ct., at 1872.

As THE CHIEF JUSTICE also explained, prosecutorial use of evidence from a psychiatric interrogation in a capital sentencing proceeding requires the protections, and warnings, accorded the Fifth Amendment right in other contexts: "Because [the defendant] did not voluntarily consent to the pretrial psychiatric examination after being informed of his right to remain silent and the possible use of his statements, the State could not rely on what he said to [the psychiatrist] to establish his future dangerousness." Id., at 468, 101 S.Ct., at 1876.

Thus, the use of petitioner's statements clearly violated the Fifth Amendment.22 In view of the majority's willingness to assume that the constitutional violation is present but that the failure to address it does not affect the fundamental fairness of petitioner's sentence, moreover, it is instructive to recall the importance of the Fifth Amendment right at issue. Again, THE CHIEF JUSTICE's opinion in Estelle v. Smith provides guidance:

"Miranda held that '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.' . . . The purpose of these admonitions is to combat what the Court saw as 'inherently compelling pressures' at work on the person and to provide him with an awareness of the Fifth Amendment privilege and the consequences of forgoing it, which is the prerequisite for 'an intelligent decision as to its exercise.'

* * * * * "The Fifth Amendment privilege is 'as broad as the mischief against which it seeks to guard,' Counselman v. Hitchcock, 142 U.S. 547, 562 [12 S.Ct. 195, 198, 142 U.S. 547] (1892), and the privilege is fulfilled only when a criminal defendant is guaranteed the right 'to remain silent unless he chooses to speak in the unfettered exercise of his own will and to suffer no penalty . . . for such silence.' Malloy v. Hogan, 378 U.S., at 1, 8 [84 S.Ct., at 1489, 1493-94, 12 L.Ed.2d 653] (1964)." Id., 451 U.S., at 466-468, 101 S.Ct., at 1874-1876.

Given the historic importance of the Fifth Amendment, and the fact that the violation of this right made a significant difference in the jury's evaluation of petitioner's "future dangerousness" (and consequent death sentence), it is not only proper, but imperative, that the federal courts entertain petitioner's entirely meritorious argument that the introduction of the psychiatrist's testimony at his sentencing hearing violated that fundamental protection.23

It is also quite clear that the introduction of the evidence violated his Eighth Amendment right to a fair sentencing proceeding. In this respect, I disagree with the Court of Appeals' reading of the opinion that I authored for the Court in Zant v. Stephens, 462 U.S. 862, 103 S.Ct. 2733, 77 L.Ed.2d 235 (1983).

The Court of Appeals concluded that, because the jury also found an aggravating circumstance of "vileness," the death sentence could stand even if Dr. Pile's testimony represented a flagrant Fifth Amendment violation.

In Zant, we held that the Georgia Supreme Court's invalidation of one of the three aggravating circumstances found by the jury did not require that the death penalty be set aside. But that conclusion was reached only after we satisfied ourselves that the evidence relating to the invalid aggravating circumstance had been properly admitted.24

We did not conclude, as the Court of Appeals seems to have assumed, that any evidence concerning the invalid circumstance was simply irrelevant because the valid circumstances were, in all events, sufficient to support the death penalty.

The fact that the record adequately establishes one valid aggravating circumstance may make the defendant eligible for the death penalty but it does not justify the conclusion that a death sentence should stand even though highly prejudicial inadmissible evidence was presented to the jury at the sentencing hearing. The introduction of such highly prejudicial, inadmissible evidence—evidence that itself represents an independent constitutional violation—quite clearly undermines the validity of the capital sentencing proceeding and violates the Eighth Amendment.

Thus, I would not only reach the merits of petitioner's constitutional claim but also would conclude that it has merit. The question that remains is the one the Court addresses in the last two paragraphs of its opinion—whether the constitutional error warrants the conclusion that the death penalty should be set aside in this habeas corpus proceeding. I think that question should be answered by reference to the language of the governing statute—the writ should issue "as law and justice require."

To hold, as the Court does today, that petitioner's death sentence must stand despite the fact that blatant constitutional violations presumably made the difference between the jury's recommendation of life or death, violates not only "law," but, quite clearly, "justice" as well.

I respectfully dissent.
