Argued February 25, 1998-Decided May 18, 1998
Respondent was convicted of first-degree murder and sentenced to death. His direct appeals and habeas petitions in the Arizona state courts were unsuccessful, and his first three federal habeas petitions were denied on the ground that he had not exhausted his state remedies. In his fourth federal habeas petition, he claimed, inter alia, that he was incompetent to be executed under Ford v. Wainwright, 477 U. S. 399. The District Court dismissed that claim as premature, but granted the writ on other grounds. In reversing the granting of the writ, the Ninth Circuit explained that its ruling was not intended to affect later litigation of the Ford claim. On remand, respondent moved to reopen his petition, fearing that review of his Ford claim might be foreclosed by the newly enacted Antiterrorism and Effective Death Penalty Act (AEDPA), which establishes a gatekeeping mechanism for the consideration of second or successive [federal] habeas corpus applications, Felker v. Turpin, 518 U. S. 651, ___; 28 U. S. C. A. §2244(b). Under AEDPA, a prisoner must ask the appropriate court of appeals to direct the district court to consider such an application, §2244(b)(3)(A), and a court of appeals decision whether to authorize an applications filing is not appealable and cannot be the subject of a petition for rehearing or a writ of certiorari, §2244(b)(3)(E). The District Court denied the motion. Subsequently, Arizona obtained a warrant for respondents execution, and the state courts found him fit to be executed. The District Court denied another motion to reopen his Ford claim, holding that it lacked jurisdiction under AEDPA. He then asked the Ninth Circuit for permission to file a successive habeas application. That court held that §2244(b) did not apply to a petition that raises only a competency to be executed claim and that respondent did not, therefore, need authorization to file his petition in the District Court.
1. Because respondents claim was not a second or successive petition under §2244(b), this Court has jurisdiction to review the Ninth Circuits judgment on the States certiorari petition. The fact that this was the second time that respondent asked the federal courts to provide relief on his Ford claim does not mean that there were two separate applications, the second of which was necessarily subject to §2244(b). There was only one application for habeas relief, and the District Court ruled (or should have ruled) on each claim when it became ripe. Since respondent was entitled to an adjudication of all of the claims presented in his earlier, undoubtedly reviewable, application, the Ninth Circuit correctly held that he was not required to get authorization to file a second or successive application before his Ford claim could be heard. Accepting the States interpretationthat once an individual has one fully litigated habeas petition, his new petition must be treated as successive-would have far reaching and seemingly perverse implications for habeas practice. This Courts cases have never suggested that a prisoner whose habeas petition was dismissed for failure to exhaust state remedies, and who then did exhaust those remedies and returned to federal court, was by such action filing a successive petition. A court would adjudicate those claims under the same standard as would govern those made in any other first petition. Respondents Ford claim-previously dismissed as premature-should be treated in the same manner, for, in both situations, the habeas petitioner does not receive an adjudication of his claim. To hold otherwise would mean that a dismissal of a first habeas petition for technical procedural reasons, having nothing to do with the claims merits, would bar the prisoner from ever obtaining federal habeas review. The States reliance on Felker v. Turpin, supra, for a contrary interpretation is misplaced. Pp. 3-7.
2. For the same reasons that this Court finds it has jurisdiction, it finds that the Ninth Circuit correctly decided that respondent was entitled to a hearing on the merits of his Ford claim in the District Court. P. 7.

CHIEF JUSTICE REHNQUIST delivered the opinion of the Court.
In Ford v. Wainwright, 477 U. S. 399, 410 (1986) we held that the Eighth Amendment prohibits a State from inflicting the penalty of death upon a prisoner who is insane. In this case, we must decide whether respondent Martinez-Villareals Ford claim is subject to the restrictions on second or successive applications for federal habeas relief found in the newly revised 28 U. S. C. A. §2244 (Supp. 1997). We conclude that it is not.Respondent was convicted on two counts of first-degree murder and sentenced to death. He unsuccessfully challenged his conviction and sentence on direct appeal in the Arizona state courts. Arizona v. Martinez-Villareal, 145 Ariz. 441, 702 P. 2d 670, cert. denied, 474 U. S. 975 (1985). He then filed a series of petitions for habeas relief in state court, all of which were denied. He also filed three petitions for habeas relief in federal court, all of which were dismissed on the ground that they contained claims on which the state remedies had not yet been exhausted.
In March 1993 respondent filed a fourth habeas petition in federal court. In addition to raising other claims, respondent also asserted that he was incompetent to be executed. Counsel for the State urged the District Court to dismiss respondents Ford claim as premature. The court did so but granted the writ on other grounds. The Court of Appeals for the Ninth Circuit reversed the District Courts granting of the writ but explained that its instruction to enter judgment denying the petition was not intended to affect any later litigation of the Ford claim. Martinez-Villareal v. Lewis, 80 F. 3d 1301, 1309, n. 1 (CA9 1996).
On remand to the District Court, respondent, fearing that the newly enacted Antiterrorism and Effective Death Penalty Act (AEDPA) might foreclose review of his Ford claim, moved the court to reopen his earlier petition. In March 1997 the District Court denied the motion and reassured respondent that it had no intention of treating the [Ford] claim as a successive petition. Martinez-Villareal v. Stewart, 118 F. 3d 628, 630 (CA9 1997). Shortly thereafter, the State obtained a warrant for respondents execution. Proceedings were then held in the Arizona Superior Court on respondents mental condition. That court concluded that respondent was fit to be executed. The Arizona Supreme Court rejected his appeal of that decision.
Respondent then moved in the Federal District Court to reopen his Ford claim. He challenged both the conclusions reached and the procedures employed by the Arizona state courts. Petitioner responded that under AEDPA, the court lacked jurisdiction. The District Court agreed with petitioner, ruling on May 16, 1997, that it did not have jurisdiction over the claim. Respondent then moved in the Court of Appeals for permission to file a successive habeas corpus application. §2244(b)(3).
The Court of Appeals stayed respondents execution so that it could consider his request. It later held that §2244(b) did not apply to a petition that raises only a competency to be executed claim and that respondent did not, therefore, need authorization to file the petition in the District Court. It accordingly transferred the petition that had been presented to a member of that court back to the District Court. Martinez-Villareal, 118 F. 3d, at 634-635.
We granted certiorari to resolve an apparent conflict between the Ninth Circuit and the Eleventh Circuit on this important question of federal law. See, e.g., In re Medina, 109 F. 3d 1556 (CA11 1996).
Before reaching the question presented, however, we must first decide whether we have jurisdiction over this case. In AEDPA, Congress established a gatekeeping mechanism for the consideration of second or successive habeas corpus applications in the federal courts. Felker v. Turpin, 518 U. S. 651, ___ (1996); §2244(b). An individual seeking to file a second or successive application must move in the appropriate court of appeals for an order directing the district court to consider his application. §2244(b)(3)(A). The court of appeals then has 30 days to decide whether to grant the authorization to file. §2244(b)(3)(D). A court of appeals decision whether to grant authorization to file a second or successive application shall not be appealable and shall not be the subject of a petition for rehearing or for a writ of certiorari. §2244(b)(3)(E).
If the Court of Appeals in this case had granted respondent leave to file a second or successive application, then we would be without jurisdiction to consider the States petition and would have to dismiss the writ. This is not, however, what the Court of Appeals did. The Court of Appeals held that the §2244(b) restrictions simply do not apply to respondents Ford claim, and that there was accordingly no need for him to apply for authorization to file a second or successive petition. We conclude today that the Court of Appeals reached the correct result in this case, and that we therefore have jurisdiction to consider the States petition.
Section 2244(b) provides:
(b)(1) A claim presented in a second or successive habeas corpus application under section 2254 that was presented in a prior application shall be dismissed.(2) A claim presented in a second or successive habeas corpus application under section 2254 that was not presented in a prior application shall be dismissed unless-
(A) the applicant shows that the claim relies on a new rule of constitutional law, made retroactive to cases on collateral review by the Supreme Court, that was previously unavailable; or (B)(i) the factual predicate for the claim could not have been discovered previously through the exercise of due diligence; and(ii) the facts underlying the claim, if proven
and viewed in light of the evidence as a whole, would be sufficient to establish by clear and convincing evidence that, but for constitutional error, no reasonable factfinder would have found the applicant guilty of the underlying offense.
If respondents current request for relief is a second or successive application, then it plainly should have been dismissed. The Ford claim had previously been presented in the 1993 petition, and would therefore be subject to dismissal under (b)(1)(A). Even if we were to consider the Ford claim to be newly presented in the 1997 petition, it does not fit within either of (b)(2)(B)s exceptions, and dismissal would still be required.The State contends that because respondent has already had one fully-litigated habeas petition, the plain meaningof §2244(b) as amended requires his new petition to be treated as successive. Brief for Petitioner 12. Under that reading of the statute, respondent is entitled to only one merits judgment on his federal habeas claims. Because respondent has already presented a petition to the District Court, and the District Court and the Court of Appeals have acted on that petition, §2244(b) must apply to any subsequent request for federal habeas relief.
But the only claim on which respondent now seeks relief is the Ford claim that he presented to the District Court, along with a series of other claims, in 1993. The District Court, acting for the first time on the merits of any of respondents claims for federal habeas relief, dismissed the Ford claim as premature, but resolved all of respondents other claims, granting relief on one. The Court of Appeals subsequently reversed the District Courts grant of relief. At that point it became clear that respondent would have no federal habeas relief for his conviction or his death sentence, and the Arizona Supreme Court issued a warrant for his execution. His claim then unquestionably ripe, respondent moved in the state courts for a determination of his competency to be executed. Those courts concluded that he was competent, and respondent moved in the federal district court for review of the state courts determination.
This may have been the second time that respondent had asked the federal courts to provide relief on his Ford claim, but this does not mean that there were two separate applications, the second of which was necessarily subject to §2244(b). There was only one application for habeas relief, and the District Court ruled (or should have ruled) on each claim at the time it became ripe. Respondent was entitled to an adjudication of all of the claims presented in his earlier, undoubtedly reviewable, application for federal habeas relief. The Court of Appeals was therefore correct in holding that respondent was not required to get authorization to file a second or successive application before his Ford claim could be heard.
If the States interpretation of second or successive were correct, the implications for habeas practice would be far-reaching and seemingly perverse. In Picard v. Connor, 404 U. S. 270, 275 (1971), we said:
It has been settled since Ex Parte Royall, 117 U. S. 241 (1886), that a state prisoner must normally exhaust available state judicial remedies before a federal court will entertain his petition for habeas corpus. . . . The exhaustion-of-state-remedies doctrine, now codified in the federal habeas statute, 28 U. S. C. §§2254(b) and (c), reflects a policy of federal-state comity. . . . It follows, of course, that once the federal claim has been fairly presented to the state courts, the exhaustion requirement is satisfied.
Later, in Rose v. Lundy, 455 U. S. 509, 522 (1982), we went further and held that a district court must dismiss habeas petitions containing both unexhausted and exhausted claims. But none of our cases expounding this doctrine have ever suggested that a prisoner whose habeas petition was dismissed for failure to exhaust state remedies, and who then did exhaust those remedies and returned to federal court, was by such action filing a successive petition. A court where such a petition was filed could adjudicate these claims under the same standard as would govern those made in any other first petition.
We believe that respondents Ford claim here-previously dismissed as premature-should be treated in the same manner as the claim of a petitioner who returns to a federal habeas court after exhausting state remedies. True, the cases are not identical; respondents Ford claim was dismissed as premature, not because he had not exhausted state remedies, but because his execution was not imminent and therefore his competency to be executed could not be determined at that time. But in both situations, the habeas petitioner does not receive an adjudication of his claim. To hold otherwise would mean that a dismissal of a first habeas petition for technical procedural reasons would bar the prisoner from ever obtaining federal habeas review. See, e.g., United States ex rel. Barnes v. Gilmore, 968 F. Supp. 384, 385 (ND Ill. 1997) (If Barnes continues in his nonpayment of the required $5 filing fee . . . this Court will be constrained to dismiss his petition); Marsh v. United States District Court for the Northern District of California, 1995 WL 23942 (ND Cal., Jan. 9, 1995) (Because petitioner has since not paid the filing fee nor submitted a signed affidavit of poverty, the petition for writ of habeas corpus is dismissed without prejudice); Taylor v. Mendoza, 1994 WL 698493 (ND Ill., Dec. 12, 1994). *
The State places great reliance on our decision in Felker v. Turpin, 518 U. S. 651 (1996), but we think that reliance is misplaced. In Felker we stated that the new restrictions on successive petitions constitute a modified res judicata rule, a restraint on what used to be called in habeas corpus practice abuse of the writ. 518 U. S., at 664. It is certain that respondents Ford claim would not be barred under any form of res judicata. Respondent brought his claim in a timely fashion, and it has not been ripe for resolution until now.
Thus, respondents Ford claim was not a second or successive petition under §2244(b) and we have jurisdiction to review the judgment of the Court of Appeals on the States petition for certiorari. But for the same reasons that we find we have jurisdiction, we hold that the Court of Appeals was correct in deciding that respondent was entitled to a hearing on the merits of his Ford claim in the District Court. The judgment of the Court of Appeals is therefore
* This case does not present the situation where a prisoner raises a Ford claim for the first time in a petition filed after the federal courts have already rejected the prisoners initial habeas application. Therefore, we have no occasion to decide whether such a filing would be a second or successive habeas corpus application within the meaning of AEDPA.
JUSTICE SCALIA, with whom JUSTICE THOMAS joins, dissenting.
It is axiomatic that the power to award the writ [of habeas corpus] by any of the courts of the United States, must be given by written law. Ex parte Bollman, 4 Cranch 75, 94 (1807) (Marshall, C. J.). And it is impossible to conceive of language that more clearly precludes respondents renewed competency-to-be-executed claim than the written law before us here: a claim presented in a second or successive habeas corpus application . . . that was presented in a prior application shall be dismissed. 28 U. S. C. A. §2244(b)(1) (Supp. 1997) (emphasis added). The Court today flouts the unmistakable language of the statute to avoid what it calls a perverse result. Ante, at 6. There is nothing perverse about the result that the statute commands, except that it contradicts pre-existing judge-made law, which it was precisely the purpose of the statute to change.
Respondent received a full hearing on his competencyto-be-executed claim in state court. The state court appointed experts and held a 4-day evidentiary hearing, after which it found respondent aware that he is to be punished for the crime of murder and . . . aware that the impending punishment for that crime is death . . . . App. 172. Respondent appealed this determination to the Supreme Court of Arizona, which accepted jurisdiction and denied relief. He sought certiorari of that denial in this Court, which also denied relief. To say that it is perverse to deny respondent a second round of timeconsuming lower-federal-court review of his conviction and sentence-because that means forgoing lower-federalcourt review of a competency-to-be-executed claim that arises only after he has already sought federal habeas on other issues-is to say that state-court determinations must always be reviewable, not merely by this Court, but by federal district courts. That is indeed the principle that this Courts imaginative habeas-corpus jurisprudence had established, but it is not a principle of natural law. Lest we forget, Congress did not even have to create inferior federal courts, U. S. Const., Art. I, §8, cl. 9; Art. III, §1, let alone invest them with plenary habeas jurisdiction over state convictions. And for much of our history, as JUSTICE
THOMAS points out, ante, at 5, prisoners convicted by validly constituted courts of general criminal jurisdiction had no recourse to habeas corpus relief at all. See Wright v. West, 505 U. S. 277, 285-286 (1992) (opinion of THOMAS, J.).It seems to me much further removed from the perverse to deny second-time collateral federal review than it is to treat state-court proceedings as nothing more than a procedural prelude to federal lower-court review of state supreme-court determinations. The latter was the regime that our habeas jurisprudence established and that AEDPA intentionally revised-to require extraordinary showings before a state prisoner can take a second trip around the extended district-court-to-Supreme-Court federal track. It is wrong for us to reshape that revision on the very lathe of judge-made habeas jurisprudence it was designed to repair.
Todays opinion resembles nothing so much as the cases of the 1920s which effectively decided that the Clayton Act, designed to eliminate federal-court injunctions against union strikes and picketing, restrained the federal courts from nothing that was previously proper. T. Powell, The Supreme Courts Control Over the Issue of Injunctions in Labor Disputes, 13 Acad. of Pol. Sci. Proc. 37, 74 (1928). In criticizing those cases as examples of Gefühlsjurisprudenz (and in insisting upon the necessity of preferring . . . the Gefühl of the legislator to the Gefühl of the judge), Dean Landis recalled Diceys trenchant observation that judge-made law occasionally represents the opinion of the day before yesterday. Landis, A Note on Statutory Interpretation, 43 Harv. L. Rev. 886, 888 (1930), quoting A. Dicey, Law and Opinion in England 369 (1926). As hard as it may be for this Court to swallow, in yesterdays enactment of AEDPA Congress curbed our prodigality with the Great Writ. The words that Landis applied to the Clayton Act fit very nicely the statute that emerges from the Courts decision in the present case: The mutilated [AEDPA] bears ample testimony to the day before yesterday that judges insist is today. 43 Harv. L. Rev., at 892. I dissent.
JUSTICE THOMAS, with whom JUSTICE SCALIA joins, dissenting.
From 1986 to 1991, respondent filed three petitions for federal habeas relief; each was dismissed on the ground that respondent had not yet exhausted his state remedies. In March 1993, respondent filed his fourth federal habeas petition presenting, inter alia, his claim under Ford v. Wainwright, 477 U. S. 399 (1986), that he was not competent to be executed. Finding that some of respondents claims were procedurally defaulted, that others were without merit, and that respondents Ford claim was not ripe for decision, the Court of Appeals held that the fourth petition should be denied. In May 1997, after the Arizona state courts rejected his Ford claim, respondent returned for a fifth time to federal court, again arguing that he was incompetent to be executed. Because this filing was a second or successive habeas corpus application, respondents Ford claim should have been dismissed. I therefore respectfully dissent.
Unlike the Court, I begin with the plain language of the statute. Section 2244(b)(1) provides that a claim presented in a second or successive habeas corpus application . . . that was presented in a prior application shall be dismissed. 28 U. S. C. A. §2244(b)(1) (Supp. 1998). An application is a putting to, placing before, preferring a request or petition to or before a person. The act of making a request for something. Blacks Law Dictionary 98-99 (6th ed. 1990); see also Websters Ninth New Collegiate Dictionary 97 (1991) (application is a request, petition . . . a form used in making a request). Respondents March 1993 federal habeas petition was clearly a habeas application (the Court concedes as much), because it placed before the District Court respondents request for a writ of habeas corpus. Once this application was denied, however, none of respondents claims for relief--including his claim that he was incompetent to be executed--remained before the Court. It was thus necessary for respondent to file a new request for habeas relief so that his Ford claim would again be pu[t] to or plac[ed] before the District Court. (The Court certainly did not raise respondents Ford claim sua sponte.) Respondents May 1997 request for relief was therefore a habeas application distinct from his earlier requests for relief, and it was thus undoubtedly second or successive.
Respondents Ford claim was also presented in both his March 1993 and his May 1997 habeas applications. To present is to bring or introduce into the presence of someone or to lay (as a charge) before a court as an object of inquiry. Websters Ninth New Collegiate Dictionary 930 (1991). Respondent clearly presented his Ford claim in both his 1993 and his 1997 habeas applications, for in each he introduced to the District Court his argument that he is not competent to be executed. Under the plain meaning of the statute, therefore, respondents Ford claim was a claim presented in a second or successive habeas corpus application . . . that was presented in a prior application. §2244(b)(1).
The reasons offered by the Court for disregarding the plain language of the statute are unpersuasive. Conceding that [t]his may have been the second time that respondent had asked the federal courts to provide relief on his Ford claim, ante, at 5, the Court nevertheless concludes that respondent has really filed only one application for habeas relief. Ibid. (emphasis added). The District Court, however, did not hold respondents Ford claim in abeyance when it denied his March 1993 habeas petition, so that claim was no longer before the District Court in May 1997. At best, then, respondents May 1997 filing was an effort to reopen his Ford claim. But that filing (which is most definitely an application) is subject to the statutory requirements for second or successive habeas applications. As we have recently stated in a closely related context:
[A] prisoners motion to recall the mandate on the basis of the merits of the underlying decision can be regarded as a second or successive application for purposes of §2244(b). Otherwise, petitioners could evade the bar against relitigation of claims presented in a prior application, §2244(b)(1), or the bar against litigation of claims not presented in a prior application, §2244(b)(2). Calderon v. Thompson, 523 U. S. __, __ (1998) (slip op., at 14).
In just the same way, habeas petitioners cannot be permitted to evade §2244(b)s prohibitions simply by moving to reopen claims already presented in a prior habeas application.
The Court also reasons that respondents Ford claim here--previously dismissed as premature--should be treated in the same manner as the claim of a petitioner who returns to a federal habeas court after exhausting state remedies, for in both situations, the habeas petitioner does not receive an adjudication of his claim. Ante, at 6-7. Implicit in the Courts reasoning is its assumption that a prisoner whose habeas petition has been dismissed for failure to exhaust state remedies, and who then exhausts those remedies and returns to federal court, has not then filed a second or successive habeas corpus application. §2244(b)(1). To be sure, none of our cases . . . ha[s] ever suggested that a prisoner in such a situation was filing a successive petition. See ante, at 6. But that is because, before enactment of the Antiterrorism and Effective Death Penalty Act of 1996 (AEDPA), 110 Stat. 1218, a federal court could grant relief on a claim in a second or successive application so long as the ground for relief had not already been presented and determined, 28 U. S. C. §2244(a) (emphasis added), or adjudicated, §2244(b), in a previous application. Claims presented in a petition dismissed for failure to exhaust are neither determined nor adjudicated. Thus, the pre-AEDPA practice of permitting petitioners to raise claims already presented in applications dismissed for failure to exhaust says nothing about whether those later applications were considered second or successive.
Even if the Court were correct that such an application would not have been considered second or successive, such a case is altogether different from this case, in which only one of many claims was not adjudicated. In the former situation, the federal court dismisses the unexhausted petition without prejudice, see Rose v. Lundy, 455 U. S. 509, 520-522 (1982), so it could be argued that the petition should be treated as if it had never been filed. In contrast, when a court addresses a petition and adjudicates some of the claims presented in it, that petition is certainly an application, and any future application must be second or successive. 1 Otherwise, the court would have adjudicated the merits of claims that had not been presented in an application. 2
Ultimately, the Courts holding is driven by what it sees as the far-reaching and seemingly perverse implications for federal habeas practice of a literal reading of the statute. Ante, at 6. Such concerns are not, in my view, sufficient to override the statutes plain meaning. And to the extent concerns about habeas practice motivate the Courts decision, it bears repeating that federal habeas corpus is a statutory right and that this Court, not Congress, has expanded the availability of the writ. Before this judicial expansion, a prisoner seeking a writ of habeas corpus was permitted to challenge only the jurisdiction of the court that had rendered the judgment under which he was in custody. See Wright v. West, 505 U. S. 277, 285-286 (1992) (opinion of THOMAS, J.). A Ford claim obviously does not present such a challenge. 3 A statute that has the effect of precluding adjudication of a claim that for most of our Nations history would have been considered noncognizable on habeas can hardly be described as perverse.
Accordingly, whether one considers respondents March 1993 federal habeas petition to have been his first habeas application-because his three previous applications had been dismissed for failure to exhaust-or his fourth-because respondent had already filed three previous habeas applications by that time-his May 1997 request for relief was undoubtedly either a second (following his first) or successive (following his fourth) habeas application. Respondents Ford claim, presented in this second or successive application, should have been dismissed as a claim . . . presented in a prior application. §2244(b)(1).
1 If the Courts position is that respondents May 1997 filing was an application, but not a second or successive one, presumably 28 U. S. C. A. §2244(b) (Supp. 1998) would not have precluded respondent from presenting, along with his Ford claim, a claim previously adjudicated on the merits, for §2244(b) operates to bar only those claims presented in second or successive applications.
2 Even if a claim dismissed without prejudice could be treated as having never been presented, dismissal, as the Court concedes, would still be required because a claim under Ford v. Wainwright, 477 U. S. 399 (1986), does not fit within §2244(b)(2)(B)s exceptions for claims not presented in prior applications. See ante, at 4.
3 There is an additional reason why a state prisoners Ford claim may not be cognizable on federal habeas. A state prisoner may bring a federal habeas petition only on the ground that he is in custody in violation of the Constitution or laws or treaties of the United States. 28 U. S. C. §2254. A Ford claim does not challenge either the prisoners underlying conviction or the legality of the sentence; it challenges when (or whether) the sentence can be carried out.
