SUPREME COURT OF THE UNITED STATES

No. 12–126

GREG McQUIGGIN, WARDEN, PETITIONER
v.
FLOYD PERKINS
on writ of certiorari to the united states
court of appeals for the sixth circuit
[May 28, 2013]
Justice Ginsburg delivered the opinion of the
Court.
This case concerns the “actual innocence”
gateway to federal habeas review applied in
Schlup v.
Delo,
513 U.S.
298 (1995), and further explained in
House v.
Bell, 547 U.S. 518 (2006). In those cases, a convincing
showing of actual innocence enabled habeas petitioners to overcome
a procedural bar to consideration of the merits of their
constitutional claims. Here, the question arises in the context of
28 U. S. C. §2244(d)(1), the statute of limitations on federal
habeas petitions prescribed in the Antiterrorism and Effective
Death Penalty Act of 1996. Specifically, if the petitioner does not
file her federal habeas peti- tion, at the latest, within one year
of “the date on which the factual predicate of the claim or claims
presented could have been discovered through the exercise of due
diligence,” §2244(d)(1)(D), can the time bar be overcome by a
convincing showing that she committed no crime?
We hold that actual innocence, if proved, serves
as a gateway through which a petitioner may pass whether the
impediment is a procedural bar, as it was in
Schlup and
House, or, as in this case, expiration of the statute of
limitations. We caution, however, that tenable actual-innocence
gateway pleas are rare: “[A] petitioner does not meet the threshold
requirement unless he persuades the district court that, in light
of the new evidence, no juror, acting reasonably, would have voted
to find him guilty beyond a reasonable doubt.”
Schlup, 513
U. S., at 329; see
House, 547 U. S., at 538 (emphasizing
that the
Schlup standard is “demanding” and seldom met). And
in making an assessment of the kind
Schlup envisioned, “the
timing of the [petition]” is a factor bearing on the “reliability
of th[e] evidence” purporting to show actual innocence.
Schlup, 513 U. S., at 332.
In the instant case, the Sixth Circuit
acknowledged that habeas petitioner Perkins (respondent here) had
filed his petition after the statute of limitations ran out, and
had “failed to diligently pursue his rights.” Order in No. 09–1875,
(CA6, Feb. 24, 2010), p. 2 (Certificate of Appealability).
Nevertheless, the Court of Appeals reversed the decision of the
District Court denying Perkins’ petition, and held that Perkins’
actual-innocence claim allowed him to pursue his habeas petition as
if it had been filed on time. 670 F.3d 665, 670 (2012). The appeals
court ap-parently considered a petitioner’s delay irrelevant to
ap-praisal of an actual-innocence claim. See
ibid.
We vacate the Court of Appeals’ judgment and
remand the case. Our opinion clarifies that a federal habeas court,
faced with an actual-innocence gateway claim, should count
unjustifiable delay on a habeas petitioner’s part, not as an
absolute barrier to relief, but as a factor in determining whether
actual innocence has been re- liably shown. See Brief for
Respondent 45 (habeas court “could . . . hold the
unjustified delay
against the petitioner when making
credibility findings as to whether the [actual-innocence] exception
has been met”).
I
A
On March 4, 1993, respondent Floyd Perkins
attended a party in Flint, Michigan, in the company of his friend,
Rodney Henderson, and an acquaintance, Damarr Jones. The three men
left the party together. Henderson was later discovered on a wooded
trail, murdered by stab wounds to his head.
Perkins was charged with the murder of
Henderson. At trial, Jones was the key witness for the prosecution.
He testified that Perkins alone committed the murder while Jones
looked on. App. 55.
Chauncey Vaughn, a friend of Perkins and
Henderson, testified that, prior to the murder, Perkins had told
him he would kill Henderson,
id., at 39, and that Perkins
later called Vaughn, confessing to his commission of the crime.
Id., at 36–38. A third witness, Torriano Player, also a
friend of both Perkins and Henderson, testified that Perkins told
him, had he known how Player felt about Henderson, he would not
have killed Henderson.
Id., at 74.
Perkins, testifying in his own defense, offered
a different account of the episode. He testified that he left
Hender-son and Jones to purchase cigarettes at a convenience store.
When he exited the store, Perkins related, Jones and Henderson were
gone.
Id., at 84. Perkins said that he then visited his
girlfriend.
Id., at 87. About an hour later, Perkins
recalled, he saw Jones standing under a streetlight with blood on
his pants, shoes, and plaid coat.
Id., at 90.
The jury convicted Perkins of first-degree
murder. He was sentenced to life in prison without the possibility
of parole on October 27, 1993. The Michigan Court of Appeals
affirmed Perkins’ conviction and sentence, and the Michigan Supreme
Court denied Perkins leave to appeal on January 31, 1997. Perkins’
conviction became final on May 5, 1997.
B
Under the Antiterrorism and Effective Death
Penalty Act of 1996 (AEDPA), 110Stat. 1214, a state prisoner
ordinarily has one year to file a federal petition for habeas
corpus, starting from “the date on which the judgment became final
by the conclusion of direct review or the ex-piration of the time
for seeking such review.” 28 U. S. C. §2244(d)(1)(A). If
the petition alleges newly discovered evidence, however, the filing
deadline is one year from “the date on which the factual predicate
of the claim or claims presented could have been discovered through
the exercise of due diligence.” §2244(d)(1)(D).
Perkins filed his federal habeas corpus petition
on June 13, 2008, more than 11 years after his conviction became
final. He alleged,
inter alia, ineffective assistance on the
part of his trial attorney, depriving him of his Sixth Amendment
right to competent counsel. To overcome AEDPA’s time limitations,
Perkins asserted newly discovered evidence of actual innocence. He
relied on three affidavits, each pointing to Jones, not Perkins, as
Henderson’s murderer.
The first affidavit, dated January 30, 1997, was
submitted by Perkins’ sister, Ronda Hudson. Hudson stated that she
had heard from a third party, Louis Ford, that Jones bragged about
stabbing Henderson and had taken his clothes to the cleaners after
the murder. App. to Pet. for Cert. 54a–55a. The second affidavit,
dated March 16, 1999, was subscribed to by Demond Louis, Chauncey
Vaughn’s younger brother. Louis stated that, on the night of the
murder, Jones confessed to him that he had just killed Henderson.
Louis also described the clothes Jones wore that night,
bloodstained orange shoes and orange pants, and a colorful shirt.
Id., at 50a–53a. The next day, Louis added, he accompanied
Jones, first to a dumpster where Jones disposed of the bloodstained
shoes, and then to the cleaners. Finally, Perkins presented the
July 16, 2002 affidavit of Linda Fleming, an employee at Pro-Clean
Cleaners in 1993. She stated that, on or about March 4, 1993, a man
matching Jones’s description entered the shop and asked her whether
bloodstains could be removed from the pants and a shirt he brought
in. The pants were orange, she recalled, and heavily stained with
blood, as was the multicolored shirt left for cleaning along with
the pants.
Id., at 48a–49a.
The District Court found the affidavits
insufficient to entitle Perkins to habeas relief. Characterizing
the affidavits as newly discovered evidence was “dubious,” the
District Court observed, in light of what Perkins knew about the
underlying facts at the time of trial.
Id., at 29a. But even
assuming qualification of the affidavits as evidence newly
discovered, the District Court next explained, “[Perkins’] petition
[was] untimely under §2244(d)(1)(D).”
Ibid. “[If] the
statute of limitations began to run as of the date of the latest of
th[e] affidavits, July 16, 2002,” the District Court noted, then
“absent tolling, [Perkins] had until July 16, 2003 in which to file
his habeas petition.”
Ibid. Perkins, however, did not file
until nearly five years later, on June 13, 2008.
Under Sixth Circuit precedent, the District
Court stated, “a habeas petitioner who demonstrates a credible
claim of actual innocence based on new evidence may, in
ex-ceptional circumstances, be entitled to equitable tolling of
habeas limitations.”
Id., at 30a
. But Perkins had not
established exceptional circumstances, the District Court
determined. In any event, the District Court observed, equitable
tolling requires diligence and Perkins “ha[d] failed utterly to
demonstrate the necessary diligence in exercising his rights.”
Id., at 31a
. Alternatively, the Dis-trict Court found
that Perkins had failed to meet the strict standard by which pleas
of actual innocence are mea-sured: He had not shown that, taking
account of all the evidence, “it is more likely than not that no
reasonable juror would have convicted him,” or even that the
evidence was new.
Id., at 30a–31a
.
Perkins appealed the District Court’s judgment.
Al-though recognizing that AEDPA’s statute of limitations had
expired and that Perkins had not diligently pursued his rights, the
Sixth Circuit granted a certificate of appealability limited to a
single question: Is reasonable diligence a precondition to relying
on actual innocence as a gateway to adjudication of a federal
habeas petition on the merits? Certificate of Appealability
2–3.
On consideration of the certified question, the
Court of Appeals reversed the District Court’s judgment. Adhering
to Circuit precedent,
Souter v.
Jones,
395 F.3d 577, 597–602 (2005), the Sixth Circuit held that
Perkins’ gateway actual-innocence allegations allowed him to
present his ineffective-assistance-of-counsel claim as if it were
filed on time. On remand, the Court of Appeals instructed, “the
[D]istrict [C]ourt [should] fully consider whether Perkins
assert[ed] a credible claim of actual innocence.” 670 F. 3d,
at 676.
We granted certiorari to resolve a Circuit
conflict on whether AEDPA’s statute of limitations can be overcome
by a showing of actual innocence. 568 U. S. ___ (2012).
Compare,
e.g., San Martin v.
McNeil, 633 F.3d 1257,
1267–1268 (CA11 2011) (“A court . . . may consider an untimely
§2254 petition if, by refusing to consider the petition for
untimeliness, the court thereby would endorse a ‘fundamental
miscarriage of justice’ because it would require that an individual
who is actually innocent remain imprisoned.”), with,
e.g.,
Escamilla v.
Jungwirth,
426 F.3d 868, 871–872 (CA7 2005) (“Prisoners claiming to be
innocent, like those contending that other events spoil the
conviction, must meet the statutory requirement of timely
action.”). See also
Rivas v.
Fischer, 687 F.3d 514,
548 (CA2 2012) (collecting cases).
II
A
In
Holland v.
Florida, 560
U. S. ___ (2010), this Court addressed the circumstances in
which a federal habeas petitioner could invoke the doctrine of
“equitable tolling.”
Holland held that “a [habeas]
petitioner is entitled to equitable tolling only if he shows (1)
that he has been pursuing his rights diligently, and (2) that some
extraordinary circumstance stood in his way and prevented timely
filing.”
Id., at ___ (slip op., at 16–17) (internal
quotation marks omitted). As the courts below comprehended, Perkins
does not qualify for equitable tolling. In possession of all three
affidavits by July 2002, he waited nearly six years to seek federal
postconviction relief. “Such a delay falls far short of
demonstrating the . . . diligence” required to entitle a petitioner
to equitable tolling. App. to Pet. for Cert. 31a (District Court
opinion). See also Certificate of Appealability 2.
Perkins, however, asserts not an excuse for
filing after the statute of limitations has run. Instead, he
maintains that a plea of actual innocence can overcome AEDPA’s
one-year statute of limitations. He thus seeks an equi-table
exception to §2244(d)(1), not an extension of the time
statutorily prescribed. See
Rivas, 687 F. 3d, at 547,
n. 42 (distinguishing from “equitable tolling” a plea to override
the statute of limitations when actual innocence is shown).
Decisions of this Court support Perkins’ view of
the significance of a convincing actual-innocence claim. We have
not resolved whether a prisoner may be entitled to habeas relief
based on a freestanding claim of actual innocence.
Herrera
v.
Collins,
506 U.S.
390, 404–405 (1993). We have recognized, however, that a
prisoner “otherwise subject to defenses of abusive or successive
use of the writ [of habeas corpus] may have his federal
constitutional claim considered on the merits if he makes a proper
showing of actual innocence.”
Id., at 404 (citing
Sawyer v.
Whitley,
505 U.S.
333 (1992)). See also
Murray v.
Carrier,
477 U.S.
478, 496 (1986) (“[W]e think that in an extraordinary case,
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.”). In other words, a credible showing of
actual innocence may allow a prisoner to pursue his constitu-tional
claims (here, ineffective assistance of counsel) on the merits
notwithstanding the existence of a procedural bar to relief. “This
rule, or fundamental miscarriage of justice exception, is grounded
in the ‘equitable discretion’ of habeas courts to see that federal
constitutional errors do not result in the incarceration of
innocent persons.”
Herrera, 506 U. S., at
404
.
We have applied the miscarriage of justice
exception to overcome various procedural defaults. These include
“successive” petitions asserting previously rejected claims, see
Kuhlmann v.
Wilson,
477 U.S.
436, 454 (1986) (plurality opinion), “abusive” petitions
asserting in a second petition claims that could have been raised
in a first petition, see
McCleskey v.
Zant,
499 U.S.
467, 494–495 (1991), failure to develop facts in state court,
see
Keeney v.
Tamayo-Reyes,
504 U.S.
1, 11–12 (1992), and failure to observe state procedural rules,
including filing deadlines, see
Coleman v.
Thompson,
501
U.S. 722, 750 (1991);
Carrier, 477 U. S., at
495–496.
The miscarriage of justice exception, our
decisions bear out, survived AEDPA’s passage. In
Calderon v.
Thompson,
523 U.S.
538 (1998), we applied the exception to hold that a federal
court may, consistent with AEDPA, recall its mandate in order to
revisit the merits of a decision.
Id., at 558 (“The
miscarriage of justice standard is altogether consistent . . . with
AEDPA’s central concern that the merits of concluded criminal
proceedings not be revisited in the absence of a strong showing of
actual innocence.”). In
Bousley v.
United States,
523 U.S.
614, 622 (1998), we held, in the context of §2255, that actual
in-nocence may overcome a prisoner’s failure to raise a
constitutional objection on direct review. Most recently, in
House, we reiterated that a prisoner’s proof of actual
innocence may provide a gateway for federal habeas review of a
procedurally defaulted claim of constitutional error. 547
U. S., at 537–538.
These decisions “see[k] to balance the societal
interests in finality, comity, and conservation of scarce judicial
re-sources with the individual interest in justice that arises in
the extraordinary case.”
Schlup, 513 U. S., at 324.
Sensitivity to the injustice of incarcerating an innocent
individual should not abate when the impediment is AEDPA’s statute
of limitations.
As just noted, see
supra, at 8, we have
held that the miscarriage of justice exception applies to state
procedural rules, including filing deadlines.
Coleman, 501
U. S., at 750. A federal court may invoke the miscarriage of
justice exception to justify consideration of claims defaulted in
state court under state timeliness rules. See
ibid. The
State’s reading of AEDPA’s time prescription would thus accord
greater force to a federal deadline than to a simi-larly designed
state deadline. It would be passing strange to interpret a statute
seeking to promote federalism and comity as requiring stricter
enforcement of federal procedural rules than procedural rules
established and enforced by the
States.
B
The State ties to §2244(d)’s text its
insistence that AEDPA’s statute of limitations precludes courts
from considering late-filed actual-innocence gateway claims.
“Section 2244(d)(1)(D),” the State contends, “forecloses any
argument that a habeas petitioner has unlimited time to present new
evidence in support of a constitutional claim.” Brief for
Petitioner 17. That is so, the State maintains, because AEDPA
prescribes a comprehensive system for determining when its one-year
limitations period begins to run. “Included within that system,”
the State observes, “is a specific trigger for the precise
circumstance presented here: a constitutional claim based on new
evidence.”
Ibid. Section 2244(d)(1)(D) runs the clock from
“the date on which the factual predicate of the claim . . . could
have been discovered through the exercise of due diligence.” In
light of that provision, the State urges, “there is no need for the
courts to act in equity to provide additional time for persons who
allege actual innocence as a gateway to their claims of
constitutional error.”
Ibid. Perkins’ request for an
equitable exception to the statute of limitations, the State
charges, would “rende[r] superfluous this carefully scripted
scheme.”
Id., at 18.
The State’s argument in this regard bears
blinders. AEDPA’s time limitations apply to the typical case in
which no allegation of actual innocence is made. The miscarriage of
justice exception, we underscore, applies to a severely confined
category: cases in which new evidence shows “it is more likely than
not that no reasonable ju- ror would have convicted [the
petitioner].”
Schlup, 513 U. S., at 329 (internal
quotation marks omitted). Section 2244(d)(1)(D) is both modestly
more stringent (because it requires diligence) and dramatically
less stringent (because it requires no showing of innocence). Many
petitions that could not pass through the actual-innocence gateway
will be timely or not measured by §2244(d)(1)(D)’s triggering
provision. That provision, in short, will hardly be rendered
superfluous by recognition of the miscarriage of justice
exception.
The State further relies on provisions of AEDPA
other than §2244(d)(1)(D), namely, §§2244(b)(2)(B) and 2254(e) (2),
to urge that Congress knew how to incorporate the miscarriage of
justice exception when it was so minded. Section 2244(b)(2)(B), the
State observes, provides that a petitioner whose first federal
habeas petition has already been adjudicated when new evidence
comes to light may file a second-or-successive petition when, and
only when, the facts underlying the new claim would “es-tablish by
clear and convincing evidence that, but for constitutional error,
no reasonable factfinder would have found the applicant guilty of
the underlying offense.” §2244(b)(2)(B)(ii). And §2254(e)(2), which
generally bars evidentiary hearings in federal habeas proceedings
ini-tiated by state prisoners, includes an exception for pris-oners
who present new evidence of their innocence. See
§§2254(e)(2)(A)(ii), (B) (permitting evidentiary hearings in
federal court if “the facts underlying the claim 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”).
But Congress did not simply incorporate the
miscarriage of justice exception into §§2244(b)(2)(B) and
2254(e)(2). Rather, Congress constrained the application of the
exception. Prior to AEDPA’s enactment, a court could grant relief
on a second-or-successive petition, then known as an “abusive”
petition, if the petitioner could show that “a fundamental
miscarriage of justice would result from a failure to entertain the
claim.”
McCleskey, 499 U. S., at 495. Section
2244(b)(2)(B) limits the exception to cases in which “the factual
predicate for the claim could not have been discovered previously
through the exercise of due diligence,” and the petitioner can
establish that no reasonable factfinder “would have found [her]
guilty of the underlying offense” by “clear and convincing
evidence.” Congress thus required second-or-successive habeas
petitioners attempting to benefit from the miscarriage of justice
exception to meet a higher level of proof (“clear and convincing
evidence”) and to satisfy a diligence requirement that did not
exist prior to AEDPA’s passage.
Likewise, petitioners asserting actual innocence
pre-AEDPA could obtain evidentiary hearings in federal court even
if they failed to develop facts in state court. See
Keeney,
504 U. S., at 12 (“A habeas petitioner’s failure to develop a
claim in state-court proceedings will be excused and a hearing
mandated if he can show that a fundamental miscarriage of justice
would result from failure to hold a federal evidentiary hearing.”).
Under AEDPA, a petitioner seeking an evidentiary hearing must show
diligence and, in addition, establish her actual innocence by clear
and convincing evidence. §§2254(e)(2)(A)(ii), (B).
Sections 2244(b)(2)(B) and 2254(e)(2) thus
reflect Congress’ will to
modify the miscarriage of justice
exception with respect to second-or-successive petitions and the
hold-ing of evidentiary hearings in federal court. These
pro-visions do not demonstrate Congress’ intent to preclude courts
from applying the exception, unmodified, to “the type of petition
at issue here”—an untimely first federal habeas petition alleging a
gateway actual-innocence claim.
House, 547 U. S., at
539.[
1] The more rational
inference to draw from Congress’ incorporation of a modified
version of the miscarriage of justice exception in §§2244(b)(2)(B)
and 2254(e)(2) is simply this: In a case not governed by those
provisions,
i.e., a first petition for federal habeas
relief, the miscarriage of justice exception survived AEDPA’s
passage intact and unrestricted.[
2]
Our reading of the statute is supported by the
Court’s opinion in
Holland. “[E]quitable principles have
traditionally governed the substantive law of habeas corpus,”
Holland reminded, and affirmed that “we will not construe a
statute to displace courts’ traditional equitable authority absent
the clearest command.” 560 U. S., at ___ (slip op., at 13)
(internal quotation marks omitted). The text of §2244(d)(1)
contains no clear command countering the courts’ equitable
authority to invoke the miscarriage of justice exception to
overcome expiration of the statute of limitations governing a first
federal habeas petition. As we observed in
Holland,
“AEDPA seeks to eliminate delays in the
federal habeas review process. But AEDPA seeks to do so without
undermining basic habeas corpus principles and while seeking to
harmonize the new statute with prior law . . . .
When Congress codified new rules governing this previously
judicially managed area of law, it did so without losing sight of
the fact that the writ of habeas corpus plays a vital role in
protecting constitutional rights.”
Id., at ___ (slip op., at
16) (citations

III
Having rejected the State’s argument that
§2244(d) (1)(D) precludes a court from entertaining an un- timely
first federal habeas petition raising a convincing claim of actual
innocence, we turn to the State’s further objection to the Sixth
Circuit’s opinion. Even if a habeas petitioner asserting a credible
claim of actual innocence may overcome AEDPA’s statute of
limitations, the State argues, the Court of Appeals erred in
finding that no threshold diligence requirement at all applies to
Perkins’ petition.
While formally distinct from its argument that
§2244(d)(1)(D)’s text forecloses a late-filed claim alleging actual
innocence, the State’s contention makes scant sense. Section
2244(d)(1)(D) requires a habeas petitioner to file a claim within
one year of the time in which new evidence “could have been
discovered through the exercise of due diligence.” It would be
bizarre to hold that a habeas
petitioner who asserts a convincing claim of
actual innocence may overcome the statutory time bar §2244(d)(1)(D)
erects, yet simultaneously encounter a court-fashioned diligence
barrier to pursuit of her petition. See 670 F. 3d, at 673
(“Requiring reasonable diligence effectively makes the concept of
the actual innocence gateway redundant, since petitioners
. . . seek [an equitable exception only] when they were
not reasonably diligent in complying with §2244(d)(1)(D).”).
While we reject the State’s argument that habeas
petitioners who assert convincing actual-innocence claims must
prove diligence to cross a federal court’s threshold, we hold that
the Sixth Circuit erred to the extent that it eliminated timing as
a factor relevant in evaluating the reliability of a petitioner’s
proof of innocence. To invoke the miscarriage of justice exception
to AEDPA’s statute of limitations, we repeat, a petitioner “must
show that it is more likely than not that no reasonable juror would
have convicted him in the light of the new evidence.”
Schlup, 513 U. S., at 327. Unexplained delay in
presenting new evidence bears on the determination whether the
petitioner has made the requisite showing. Perkins so
acknowl-edges. See Brief for Respondent 52 (unjustified delay may
figure in determining “whether a petitioner has made a sufficient
showing of innocence”). As we stated in
Schlup, “[a] court
may consider how the timing of the submission and the likely
credibility of [a petitioner’s] affiants bear on the probable
reliability of . . . evidence [of actual innocence].” 513
U. S., at 332. See also
House, 547 U. S., at
537.
Considering a petitioner’s diligence, not
discretely, but as part of the assessment whether actual innocence
has been convincingly shown, attends to the State’s concern that it
will be prejudiced by a prisoner’s untoward delay in proffering new
evidence. The State fears that a prisoner might “lie in wait and
use stale evidence to collaterally
attack his conviction . . . when an
elderly witness has died and cannot appear at a hearing to rebut
new evidence.” Brief for Petitioner 25. The timing of such a
petition, however, should seriously undermine the credibility of
the actual-innocence claim. Moreover, the deceased witness’ prior
testimony, which would have been subject to cross-examination,
could be introduced in the event of a new trial. See
Crawford v.
Washington,
541 U.S.
36, 53–54 (2004) (recognizing exception to the Confrontation
Clause where witness is unavailable and the defendant had a prior
opportunity for cross-examination). And frivolous petitions should
occasion instant dismissal. See 28 U. S. C. §2254 Rule 4.
Focusing on the merits of a petitioner’s actual-innocence claim and
taking account of delay in that context, rather than treating
timeliness as a threshold inquiry, is tuned to the rationale
underlying the miscarriage of justice exception—
i.e.,
ensuring “that federal constitutional errors do not result in the
incarceration of innocent persons.”
Herrera, 506 U. S.,
at 404.[

IV
We now return to the case at hand. The
District Court proceeded properly in first determining that
Perkins’ claim was filed well beyond AEDPA’s limitations period and
that equitable tolling was unavailable to Perkins because he could
demonstrate neither exceptional circumstances nor diligence. See
supra, at 5. The District Court then found that Perkins’
alleged newly discovered evidence,
i.e., the information
contained in the three affidavits, was “substantially available to
[Perkins] at trial.”
App. to Pet. for Cert. 31a. Moreover, the
proffered evidence, even if “new,” was hardly adequate to show
that, had it been presented at trial, no reasonable juror would
have convicted Perkins.
Id., at 30a–31a.
The Sixth Circuit granted a certificate of
appealability limited to the question whether reasonable diligence
is a precondition to reliance on actual innocence as a gateway to
adjudication of a federal habeas petition on the merits. We have
explained that untimeliness, although not an unyielding ground for
dismissal of a petition, does bear on the credibility of evidence
proffered to show actual innocence. On remand, the District Court’s
appraisal of Perkins’ petition as insufficient to meet
Schlup’s actual-innocence standard should be dispositive,
absent cause, which we do not currently see, for the Sixth Circuit
to upset that evaluation. We stress once again that the
Schlup standard is demanding. The gateway should open only
when a petition presents “evidence of innocence so strong that a
court cannot have confidence in the outcome of the trial unless the
court is also satisfied that the trial was free of nonharmless
constitutional error.” 513 U. S., at 316.
* * *
For the reasons stated, the judgment of the
Sixth Circuit is vacated, and the case is remanded for further
proceedings consistent with this opinion.
It is so ordered.
