    SUMMARY **
    Habeas Corpus
    The panel (1) affirmed the district court’s dismissal of
    California state prisoner Gregory Brown’s second-in-time
    habeas corpus petition for failure to obtain authorization
    from this court to file a second or successive petition, and
    (2) denied his application for leave to file a second or
    successive petition.
    Brown’s second-in-time habeas petition alleged failure
    to disclose materially exculpatory evidence under Brady v.
    Maryland. The panel held that Brady claims are subject to
    AEDPA’s second or successive gatekeeping requirements
    because the factual predicate supporting a Brady claim – the
    state’s failure to disclose exculpatory evidence before trial –
    exists at the time of the first habeas petition.
    Considering the exculpatory evidence individually and
    together with the evidence presented at trial, the panel held
    that Brown fails to make a prima showing of actual
    innocence by clear and convincing evidence. The panel
    therefore denied his application for leave to file a second or
    successive petition.

    This summary constitutes no part of the opinion of the court. It
    has been prepared by court staff for the convenience of the reader.

    OPINION
    CALLAHAN, Circuit Judge:
    We must decide whether a prisoner’s second-in-time
    habeas petition based on a claim under Brady v. Maryland,
    
    373 U.S. 83
     (1963) is second or successive for purposes of
    federal court review. The State of California disclosed
    allegedly exculpatory evidence in Petitioner Gregory
    Brown’s case after Brown’s initial federal habeas petition
    was denied. Because he did not know of the evidence at the
    time of his initial petition, Brown argues he should not be
    subject to the more stringent standard for seeking habeas
    relief in any subsequent federal petition.
    We conclude that Brown’s argument is foreclosed by the
    plain text of the Antiterrorism and Effective Death Penalty
    Act of 1996 (“AEDPA”), binding Supreme Court and Ninth
    Circuit precedent, and Congress’ intent in enacting AEDPA.
    We therefore apply AEDPA’s second or successive bar to
    Brown’s claim and assess whether he has made the requisite
    4                         BROWN V. MUNIZ
    prima facie showing of actual innocence. Because the
    alleged exculpatory evidence falls short of this standard, we
    affirm the district court’s dismissal of Brown’s petition for
    lack of jurisdiction and deny his application for leave to file
    a second or successive habeas petition with the district
    court. 1
    I.
    Gregory Brown is currently serving a sentence of fifty-
    six years-to-life for the February 7, 1995 attempted murder
    of Ms. Robin Williams. Brown was convicted by a jury of
    one count of conspiracy to commit murder and one count of
    attempted murder in California state court on an aiding and
    abetting theory. His two co-defendants, Wanda Fain and
    Joseph Diggs, were also convicted.
    A.
    The following facts were presented to the jury at the trial
    of the three co-defendants. On January 6, 1995, Williams
    was at the home of Brown, Fain, and Diggs in San Francisco.
    Williams lived nearby, and frequented Brown’s home.
    Responding to a domestic disturbance nearby, police
    approached Brown’s home, where they found Brown in the
    doorway holding a bag of crack cocaine and a gun. The
    police arrested Brown and Williams. That same day,
    Williams gave a statement to the police that she had seen
    Brown with both the cocaine and the gun.
    About a week-and-a-half later, and while Brown was
    awaiting trial on drug charges stemming from his January 6
    arrest, Fain and Brown approached Williams at a neighbor’s
    1
    Brown’s motion for judicial notice (Dkt. No. 17) is GRANTED.
    BROWN V. MUNIZ                           5
    home. As Brown looked on, Fain gave Williams a note that
    stated: “Well, well, well, as you know playing with fire get
    burned. Silence is the very best policy, bitch. P.S.: Chickens
    get plucked every day, so don’t play.” Included with the note
    was an explicit photo of Williams that Brown had taken
    years earlier. Fain then told Williams that Brown wanted to
    speak with her. Williams refused because she was scared.
    Fain and Brown left the residence.
    Brown later ran into Williams on the street. Brown told
    her that he would take care of her if she did not testify against
    him in his drug case. After that conversation, Williams
    resumed her visits to Brown’s residence where, on at least
    one occasion, the two smoked crack cocaine.
    According to Williams, on the day of the attempted
    murder, she traveled to and from Brown and Fain’s residence
    several times, smoking crack cocaine throughout the day.
    When she arrived at the residence at 7 p.m. to see Fain, she
    saw that Brown and Fain were talking (Diggs was also
    present), and so left to take a walk. She returned about five
    minutes later. By that time Brown had left. Fain asked
    Williams if she wanted to go to a “trick house” on Third
    Street so that they could prostitute themselves. Williams
    agreed because she wanted money to pay for more drugs.
    Williams, Fain, and Diggs left the residence at around
    7:30 p.m. Fain told Williams that Diggs was joining them to
    provide protection. Williams was “very high” at the time.
    Brown did not accompany them. Notably, expert testimony
    established that Williams’ habitual crack cocaine use,
    combined with the head injury she sustained from being shot
    in the head later that evening, could have impaired her
    memory of that evening’s events.
    From that point on, the accounts of Williams, Fain, and
    Diggs diverge. Williams testified that she, Fain, and Diggs
    6                    BROWN V. MUNIZ
    boarded a bus together at around 7:30 p.m. The three
    departed the bus at the corner of Third and Jerrold Streets.
    From there, Williams testified that she and Fain walked
    down the street, laughing and talking, with Diggs following
    behind. Williams’ last recollection before she was shot was
    a car approaching her from behind. The police never
    identified the car.
    In contrast, Diggs told Officer Jeffrey Levin that he got
    off the bus with Williams and then went into a nearby
    Kentucky Fried Chicken on his own. He stated that he later
    re-boarded a bus, leaving Williams behind.
    Fain’s account of her movements is both internally
    inconsistent and contrary to Diggs’ account. Fain first told
    Levin that she met up with Diggs for the first time at the
    Third and Jerrold Street bus stop—i.e., after she departed the
    bus. But later she said that she got on the bus with both
    Williams and Diggs.
    The defense introduced several pieces of exculpatory
    evidence. Besides the fact that no forensics connected Fain
    or Diggs—let alone Brown—to the attempted murder, the
    defense also introduced impeachment evidence against
    Williams. The defense showed that Williams had been
    involved in altercations with others in the past, was beaten
    up for committing burglary, and had informed on
    perpetrators in other crimes—all of which suggested that
    individuals other than the co-defendants may have had a
    motive to kill Williams. The jury also heard testimony that
    a man known as “Tails” had threatened Williams at gunpoint
    the day before the attempted murder. Finally, the jury heard
    from Angel Stigert, who found Williams lying in the street
    after she was shot. Stigert saw a car parked two blocks away
    with someone standing outside, “crouching over [and]
    looking toward where [Williams’] body was.” Stigert
    BROWN V. MUNIZ                       7
    offered a vague description of “a big black person with [a]
    white T-shirt.” The mysterious interloper, thereafter
    nicknamed “Suspect 1,” was never identified. Despite the
    exculpatory evidence, the jury convicted Brown, Fain, and
    Diggs.
    B.
    In 1998, the California Court of Appeal affirmed the
    convictions and sentences of all three co-defendants and the
    California Supreme Court denied review. The Court of
    Appeal discussed the inculpatory facts in Brown’s case. On
    the conspiracy charge, the court noted that (1) Brown had a
    motive to murder Williams because he was angry with her
    for talking to the police and wanted to prevent her from
    testifying against him in his drug case; (2) he demonstrated
    an intent to act on these motives through specific actions—
    namely, “he directed Fain to prepare and deliver the
    threatening note; he gave Fain a suggestive photograph of
    Williams to attach to the note; he accompanied Fain when
    the note was delivered but waited outside and had Fain tell
    Williams that he wanted to speak with her privately”; (3) he
    told Williams he would protect her if she did not testify
    against him in his drug case; (4) on the day of the shooting
    Brown was present with Fain and Diggs at their apartment
    when Williams arrived; and (5) Brown left shortly before
    Fain suggested that she and Williams prostitute
    themselves—an excursion that culminated in Williams’
    attempted murder. As to the last fact, the Court of Appeal
    concluded that “[t]he jury could reasonably infer that Brown
    left the apartment so Williams would not become suspicious:
    not because he was unaware of some hidden agreement
    between Fain and Diggs.”
    On the charge of aiding and abetting attempted murder,
    the court found that, based on the same evidence supporting
    8                    BROWN V. MUNIZ
    the conspiracy conviction, the jury could have reasonably
    concluded that Brown at least intended to aid and abet Fain
    and Diggs in the attempted murder, even if he did not
    personally intend to kill Williams.
    In 1998, after the Court of Appeal affirmed his
    convictions, Brown filed a writ of habeas corpus in federal
    district court, which the court denied on the merits. The
    court refused to grant a Certificate of Appealability
    (“COA”), as did the Ninth Circuit, thereby concluding
    Brown’s first attempt at federal habeas relief.
    C.
    New evidence came to light more than a decade later.
    Between October 2010 and May 2011, the Trial Integrity
    Unit of the San Francisco District Attorney’s (“DA”) Office
    issued letters to the San Francisco County Public Defender’s
    Office and San Francisco Bar Association’s Indigent
    Defense Administrator, stating that three San Francisco
    Police Department officers had material in their personnel
    files that was previously undisclosed and which “may be
    subject to disclosure under Brady v. Maryland (1963)
    
    373 U.S. 83
    .” The letters implicated three officers who were
    in some way related to Brown’s case: Ms. Pamela Hockett
    (May 19, 2011), Sergeant Michael Hutchings (Apr. 29,
    2011), and Sergeant Wallace Gin (Oct. 6, 2010).
    The Hockett information dates back to 1987, the
    Hutchings information to 1989, and the Gin information to
    1988—long before the officers’ associations with the
    Brown, Fain, and Diggs case. The letters state that the DA’s
    office was not conceding that any of the information was
    exculpatory or that it cast doubt upon the correctness of any
    convictions.
    BROWN V. MUNIZ                                 9
    The material implicating Hockett is potential
    impeachment evidence. It shows that more than a decade
    before Brown’s trial, Hockett was arrested on charges of
    drug possession, carrying a concealed firearm, having a
    hypodermic needle, and carrying a loaded firearm in a public
    place. The charges were dismissed. Hockett did not testify
    at Brown’s trial or at any preliminary hearing. She was,
    however, one of the officers who responded to the crime
    scene. She also produced a crime scene log listing the
    comings and goings of police personnel. No claim is made
    that the crime scene log was inculpatory or exculpatory, in
    and of itself.
    The material implicating Hutchings is also potential
    impeachment evidence. The information involves a 1984
    charge against Hutchings for loitering where children
    congregate, resisting arrest, and prostitution. The charges
    were dismissed after diversion. Like Hockett, Hutchings
    also did not testify at Brown’s trial or at any preliminary
    hearing. Nor did Hutchings have any involvement in
    Brown’s attempted murder case. Hutchings’ association
    with Brown stemmed from his participation in Brown’s
    January 1995 arrest for drug possession. In fact, Hutchings
    was a defense witness at a pretrial motion to suppress the
    drug evidence.
    The material implicating Gin involves an unrelated
    matter that predated the Williams shooting by seven years. 2
    Of the three officers, Gin was the most closely involved in
    Brown’s case: unlike Hockett and Hutchings, Gin testified
    at Brown’s trial. And while Gin had no role in the
    investigation and did not interview the co-defendants or the
    2
    The material itself is filed under seal and is not reproduced in this
    opinion.
    10                    BROWN V. MUNIZ
    victim, he interviewed the driver of a bus who happened
    upon Williams’ body, as well as two passengers on the bus.
    The information in Gin’s investigation report was
    corroborated by live witnesses, including the bus driver, who
    testified at Brown’s trial.
    In 2014, Brown filed a second-in-time habeas petition in
    federal district court under 
    28 U.S.C. § 2254
    , alleging that
    the Hockett, Hutchings, and Gin information was materially
    exculpatory Brady evidence. The district court dismissed
    Brown’s petition without prejudice for lack of jurisdiction.
    It determined that the petition was second or successive, and
    therefore Brown was required to obtain authorization from
    the Ninth Circuit to file his petition in order for the district
    court to assert jurisdiction. The district court granted a COA
    on the question of whether Brown’s petition was second or
    successive, and Brown timely appealed.
    II.
    We review a district court’s dismissal of a habeas
    petition as second or successive de novo. Wentzell v. Neven,
    
    674 F.3d 1124
    , 1126 (9th Cir. 2012). Our review of an
    application to file a second or successive habeas petition is
    governed by the standard set forth in AEDPA, as is our
    determination of whether a second-in-time habeas petition is
    second or successive under AEDPA. See 
    28 U.S.C. § 2244
    (b)(2)–(b)(3).
    A.
    First-in-time habeas petitions filed in federal court are
    subject to AEDPA § 2254, which provides that
    [a]n application for a writ of habeas corpus
    on behalf of a person in custody pursuant to
    BROWN V. MUNIZ                      11
    the judgment of a State court shall not be
    granted with respect to any claim that was
    adjudicated on the merits in State court
    proceedings unless the adjudication of the
    claim—
    (1) resulted in a decision that was
    contrary to, or involved an unreasonable
    application of, clearly established Federal
    law, as determined by the Supreme Court
    of the United States; or
    (2) resulted in a decision that was based
    on an unreasonable determination of the
    facts in light of the evidence presented in
    the State court proceeding.
    
    28 U.S.C. § 2254
    (d).
    A different and more demanding standard governs most
    second-in-time federal habeas petitions, termed “second or
    successive.” While AEDPA does not define “second or
    successive,” we have looked to the text of the statute, the
    corpus of Supreme Court jurisprudence interpreting
    § 2244(b), and the pre-AEDPA abuse-of-the-writ doctrine to
    trace its contours. It is now understood that a federal habeas
    petition is second or successive if the facts underlying the
    claim occurred by the time of the initial petition, Panetti v.
    Quarterman, 
    551 U.S. 930
    , 945 (2007), and if the petition
    challenges the same state court judgment as the initial
    petition, Magwood v. Patterson, 
    561 U.S. 320
    , 333 (2010)
    (explaining that a writ of habeas corpus is filed “‘on behalf
    of a person in custody pursuant to the judgment of a State
    court.’” (emphasis in opinion) (quoting 
    28 U.S.C. § 2254
    (b)). Stating the second criterion in the converse, a
    12                     BROWN V. MUNIZ
    petition is not second or successive if it is based on an
    intervening state court judgment—e.g., a new sentencing
    determination—notwithstanding that the same claim
    challenging a conviction (or even the new sentence) could
    have been brought in the first petition. See Magwood,
    
    561 U.S. at
    331–36. Nor is a petition second or successive
    if the factual predicate for the claim accrued only after the
    time of the initial petition. United States v. Buenrostro, 
    638 F.3d 720
    , 725–26 (9th Cir. 2011) (per curiam).
    If the petition is second or successive, then the district
    court lacks jurisdiction and must dismiss the petition unless
    and until the court of appeals grants an application to file it.
    
    28 U.S.C. § 2244
    (b)(3)(A).         In evaluating such an
    application, the court of appeals is bound by § 2244(b)’s
    gatekeeping requirements:
    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
    BROWN V. MUNIZ                              13
    (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.
    Id. § 2244(b)(2). 3 Thus, absent a showing of intervening
    constitutional law, a second or successive habeas petitioner
    must overcome two obstacles to invoke the district court’s
    jurisdiction: he must (1) show that the factual predicate for
    his habeas claim reasonably could not have been discovered
    at the time of his initial habeas petition, and (2) demonstrate
    that the previously undiscovered facts, if shown to be true in
    a habeas action, suffice to prove his innocence by clear and
    convincing evidence. Buenrostro, 
    638 F.3d at
    725–26. 4
    3
    The Supreme Court upheld § 2244(b) as consistent with the
    Suspension Clause of the United States Constitution in Felker v. Turpin,
    
    518 U.S. 651
    , 664 (1996). The Suspension Clause provides that “[t]he
    Privilege of the Writ of Habeas Corpus shall not be suspended, unless
    when in Cases of Rebellion or Invasion the public Safety may require
    it.” U.S. Const., art. I, § 9, cl. 2.
    4
    Buentrostro involved AEDPA § 2255(h), not § 2244(b). Section
    2255(h) governs second or successive habeas petitions filed pursuant to
    a federal court judgment, rather than a state court judgment, but it
    incorporates by reference and applies the standard set forth in § 2244.
    Our circuit cites cases interpreting both provisions interchangeably. See,
    e.g., Gage, 793 F.3d at 1165 (a case applying § 2244, and relying on
    Buenrostro).
    14                        BROWN V. MUNIZ
    B.
    We conclude that Brady claims are subject to AEDPA’s
    second or successive gatekeeping requirements because the
    “factual predicate [supporting a Brady claim] existed at the
    time of the first habeas petition.” Gage v. Chappell,
    
    793 F.3d 1159
    , 1165 (9th Cir. 2015). This conclusion is
    compelled by the plain text of § 2244(b), Supreme Court
    precedent, and our own case law.
    1. We begin, as always, with the plain text of the statute.
    Hughes Aircraft Co. v. Jacobson, 
    525 U.S. 432
    , 438 (1999).
    Section 2244(b)(2)(B)(i) applies the second or successive
    bar to claims in which “the factual predicate for the claim
    could not have been discovered previously through the
    exercise of due diligence.” Two premises necessarily
    underpin this provision: the factual predicate must have
    existed previously, and the defense must not have known
    about it. Section 2244(b) therefore essentially defines a
    Brady-type event. 5 It follows ineluctably that Brady claims
    are therefore subject to § 2244(b).
    2. Supreme Court case law accords with this
    interpretation. The Court has explained that § 2244(b)
    applies to second-in-time habeas petitions except where the
    factual predicate did not exist at the time of the initial habeas
    petition. See Panetti, 
    551 U.S. at 945
    .
    5
    We note that, should exculpatory evidence be discovered by the
    State after the first habeas petition is filed, and is thereafter suppressed
    by the State over the course of post-conviction proceedings, the result
    would be different. In that event, the factual predicate for a Brady claim
    would have accrued only after the petitioner filed his initial petition, and
    so the new claim would not have been ripe at the time of the initial filing.
    See Panetti, 
    551 U.S. at 945
    .
    BROWN V. MUNIZ                             15
    In Panetti, the Court assessed a death row inmate’s
    second-in-time habeas petition—brought years after his
    initial petition was denied—in which he argued that his
    death sentence was unconstitutional under Ford v.
    Wainwright, 
    477 U.S. 399
     (1986) because he was insane.
    Ford ruled that the Eighth Amendment precludes the
    government from executing an insane inmate. Ford,
    
    477 U.S. at
    409–10. Because a claim ripens only at the time
    the factual predicate supporting a habeas claim accrues,
    Panetti explained that “Ford-based incompetency claims, as
    a general matter, are not ripe until after the time has run to
    file a first federal habeas petition”—and oftentimes not until
    execution is imminent. Id.; Magwood, 
    561 U.S. at
    335 n.11.
    Panetti therefore deemed the inmate’s petition not to be
    second or successive because his Ford claim did not ripen
    until just before the time of his execution. Panetti, 
    551 U.S. at 945
    . In reaching this conclusion, the Court considered
    (1) its own case law both pre- and post-AEDPA, and
    (2) AEDPA’s purposes.

    First, Panetti looked to the Court’s decisions in Slack v.
    McDaniel, 
    529 U.S. 473
    , 486 (2000), and Stewart v.
    Martinez-Villareal, 
    523 U.S. 637
    , 644 (1998). Slack held
    that a pre-AEDPA petition was not second or successive
    notwithstanding that it challenged the same state court
    judgment, because it merely supplemented a first-in-time
    petition that was dismissed for lack of exhaustion. 6 
    529 U.S. at 487
    . Martinez-Villareal reached the same conclusion with
    regard to a Ford claim that the petitioner, unlike the
    petitioner in Panetti, had raised in his first habeas petition.
    
    523 U.S. at 644
    . The district court dismissed the first
    petition, however, because it was unripe at the time. 
    Id.
     In
    6
    The Court implied that it would have reached the same result under
    AEDPA. 
    529 U.S. at 486
    .
    16                   BROWN V. MUNIZ
    discussing the rationale behind Martinez-Villareal, the Court
    in Panetti explained the unusual circumstance presented by
    Ford claims:
    While the later filing “may have been the
    second time that [the prisoner] had asked the
    federal courts to provide relief on his Ford
    claim,” the Court declined to accept that there
    were, as a result, “two separate applications,
    [with] the second . . . necessarily subject to
    § 2244(b).” The Court instead held that, in
    light of the particular circumstances
    presented by a Ford claim, it would treat the
    two filings as a single application. The
    petitioner “was entitled to an adjudication of
    all of the claims presented in his earlier,
    undoubtedly reviewable, application for
    federal habeas relief.”
    
    551 U.S. at
    944–45 (quoting Martinez-Villareal, 
    523 U.S. at 643
    ). Rather than limiting Martinez-Villareal to exempting
    only those Ford claims that were actually brought as (unripe)
    claims in an initial petition, Panetti couched Martinez-
    Villareal in a broader doctrinal context. The Court
    concluded that “Congress did not intend the provisions of
    AEDPA addressing ‘second or successive’ petitions to
    govern a filing in the unusual posture presented here: a
    § 2254 application raising a Ford-based incompetency claim
    filed as soon as that claim is ripe.” Id. at 945.
    Panetti fortified its conclusion by considering Congress’
    intent under AEDPA, and the “practical effects” of its
    holding. Id. The Court explained that
    [t]he statute’s design is to “further the
    principles of comity, finality, and
    BROWN V. MUNIZ                      17
    federalism.” Miller-El v. Cockrell, 
    537 U.S. 322
    , 337, 
    123 S. Ct. 1029
    , 
    154 L.Ed.2d 931
    (2003) (internal quotation marks omitted).
    Cf. Day v. McDonough, 
    547 U.S. 198
    , 205–
    206, 
    126 S. Ct. 1675
    , 
    164 L.Ed.2d 376
     (2006)
    (“The AEDPA statute of limitation promotes
    judicial efficiency and conservation of
    judicial resources, safeguards the accuracy of
    state court judgments by requiring resolution
    of constitutional questions while the record is
    fresh, and lends finality to state court
    judgments within a reasonable time” (internal
    quotation marks omitted)).
    
    Id.
     The Court determined that requiring a petitioner to file
    an unripe Ford claim to preserve the right to full habeas
    review of that claim—a la Martinez-Villareal—would
    frustrate Congress’ goals:
    An empty formality requiring prisoners to
    file unripe Ford claims neither respects the
    limited legal resources available to the States
    nor encourages the exhaustion of state
    remedies . . . . Instructing prisoners to file
    premature claims, particularly when many of
    these claims will not be colorable even at a
    later date, does not conserve judicial
    resources, “reduc[e] piecemeal litigation,” or
    “streamlin[e] federal habeas proceedings.”
    Burton v. Stewart, 
    549 U.S. 147
    , 154, 
    127 S. Ct. 793
    , 797, 
    166 L.Ed.2d 628
     (2007) (per
    curiam) (internal quotation marks omitted).
    AEDPA’s concern for finality, moreover, is
    not implicated, for under none of the possible
    approaches would federal courts be able to
    18                        BROWN V. MUNIZ
    resolve a prisoner’s Ford claim before
    execution is imminent.         See Martinez-
    Villareal, 
    supra,
     at 644–645 (acknowledging
    that the District Court was unable to resolve
    the prisoner’s incompetency claim at the time
    of his initial habeas filing).
    Id. at 946. The Court ultimately held that petitions “that
    would require unripe (and, often, factually unsupported)
    claims to be raised as a mere formality, to the benefit of no
    party,” are not second or successive under AEDPA. Id. at
    947. Thus, “the statutory bar on ‘second or successive’
    applications does not apply to a Ford claim brought in an
    application filed when the claim is first ripe.” 7 Id.
    7
    Panetti marked the Supreme Court’s first foray into the area of
    unripe claims filed after a habeas petition has been decided, but it was
    not the first court to venture into the patch. Over the span of nearly two
    decades, several lower courts have recognized that unripe claims—albeit
    outside the Ford context—are not subject to the second or successive bar
    when properly raised in a subsequent federal habeas petition. See, e.g.,
    Hill v. Alaska, 
    297 F.3d 895
    , 898–99 (9th Cir. 2002) (challenge to release
    date based on post-sentencing parole determination was not second or
    successive because the factual predicate—calculation of the release
    date—occurred after petitioner filed his initial petition); Medberry v.
    Crosby, 
    351 F.3d 1049
    , 1062 (11th Cir. 2003) (challenge to prison
    disciplinary proceeding was not second or successive because it “could
    not have been raised in an earlier petition” challenging petitioner’s
    conviction or sentence); James v. Walsh, 
    308 F.3d 162
    , 168 (2d Cir.
    2002) (challenge to calculation of release date was not second or
    successive because it was based on facts that “did not exist” at the time
    of the initial habeas petition); Crouch v. Norris, 
    251 F.3d 720
    , 725 (8th
    Cir. 2001) (claim stemming from a refusal to grant parole was not second
    or successive because the facts underlying the claim did not exist at the
    time of the initial habeas petition); In re Cain, 
    137 F.3d 234
    , 235–36 (5th
    Cir. 1998) (challenge to prison disciplinary decision was not second or
    successive because it occurred after petitioner filed his initial habeas
    BROWN V. MUNIZ                                 19
    Panetti’s limited exception to § 2244(b) comports with
    the plain text of § 2244(b)(2)(B)(i): whereas a Brady claim
    involves a “factual predicate” that existed but could
    previously “not have been discovered,” an unripe claim
    involves no previously existing “factual predicate” at all.
    Section 2244(b)(2)(B)(i) simply does not contemplate such
    a scenario.
    Treating unripe claims as second or successive is also
    inconsistent with AEDPA’s purposes of promoting comity,
    finality, federalism, and judicial efficiency, as Panetti
    explained. See Panetti, 
    551 U.S. at
    946–47. Doing the same
    for Brady claims, by contrast, serves AEDPA’s goals. It
    gives due regard to States’ administration of their own
    criminal justice systems by limiting collateral attacks on
    state court judgments to those where “extreme malfunctions
    in the state criminal justice systems” occurred. Harrington
    v. Richter, 
    562 U.S. 86
    , 102–03 (2011) (emphasis added). In
    the same vein, by recognizing only those Brady claims that
    show by clear and convincing evidence a petitioner’s actual
    innocence, a court of appeals acts consistent with Congress’
    purpose of keeping the federal courts’ focus on ensuring the
    integrity of a verdict, rather than second-guessing state court
    judgments. See id.; see also Davis v. Ayala, 
    135 S. Ct. 2187
    ,
    petition); Walker v. Roth, 
    133 F.3d 454
    , 455 (7th Cir. 1997) (per curiam)
    (petition was not second or successive because it “challenge[d] the
    constitutionality of a proceeding which obviously occurred after
    [petitioner] filed, and obtained relief, in his first habeas petition”);
    United States v. Scott, 
    124 F.3d 1328
    –29, 1330 (10th Cir. 1997) (petition
    was not second or successive where ineffective assistance of appellate
    counsel claim raised in the petition did not exist at the time of petitioner’s
    initial petition); cf. Benchoff v. Colleran, 
    404 F.3d 812
    , 817–18 (3d Cir.
    2005) (because challenged parole determination occurred before
    petitioner filed his first habeas petition, his subsequent challenge was
    second or successive).
    20                    BROWN V. MUNIZ
    2199 (2015) (habeas relief is available only where the state
    court’s decision was so unreasonable that there is no
    “possibility for fairminded disagreement” (internal
    quotation marks omitted)).
    In sum, having reviewed § 2244(b)’s plain text and the
    Supreme Court’s narrowly circumscribed exception for
    unripe claims, we decline to read into the Court’s decisions
    an additional and qualitatively different exception for Brady
    claims.
    3. Finally, our own case law accords with this
    interpretation. Indeed, we explained this very distinction in
    Buenrostro, albeit in the context of an ineffective assistance
    of counsel (“IAC”) claim. 
    638 F.3d at
    725–26. Buenrostro
    involved a petitioner serving a life sentence for federal drug
    crimes. 
    Id. at 721
    . After the district court denied his initial
    petition, Buenrostro discovered that his trial attorney had
    rejected a plea deal that would have limited his sentence to
    fourteen years. 
    Id.
     Buenrostro argued that his attorney’s
    rejection of the deal amounted to deficient performance, and
    that his case should be reopened under Federal Rule of Civil
    Procedure 60(b). 
    Id.
    The district court construed Buenrostro’s motion as
    second or successive under § 2255—the federal court analog
    to § 2244. Id. A panel of this court agreed and, applying
    § 2255’s “actual innocence standard,” denied his application
    to file his petition in district court. Id. at 725–26. Buenrostro
    then went on to distinguish Panetti. It explained that Panetti
    is limited to the narrow circumstance of a claim that does not
    ripen until after an initial habeas petition is decided. Id. at
    725. Buenrostro’s IAC claim, by contrast, was ripe at the
    time of his first habeas petition: the alleged constitutional
    error had already occurred, and the district court would have
    had jurisdiction to rule on it. See id. at 725–26. Buenrostro
    BROWN V. MUNIZ                          21
    just didn’t know about it. The court held that § 2255
    addresses this precise scenario, and explained that “the
    words of § 2255(h) indicate Congress’ clear intent to
    prohibit us from certifying second-in-time claims, ripe at the
    time of a prisoner’s first § 2255 proceeding but not
    discovered until afterward,” unless the petitioner can satisfy
    § 2255’s criteria. Id.
    Our subsequent decision in Gage also concerned facts
    discovered after trial but before the filing of an initial habeas
    petition. But in Gage, those facts supported a Brady rather
    than an IAC claim. Gage was serving a 70-year sentence for
    sexually assaulting his daughter. Gage, 793 F.3d at 1163.
    After he was convicted but before he was sentenced, the trial
    judge ordered the state to turn over the victim’s medical and
    psychiatric records for in camera review. Id. While Gage
    was not permitted to view the records, the trial court
    disclosed some of their contents—namely, that the victim’s
    mother—Gage’s ex-wife—had described her daughter as a
    “pathological liar.” Id. Armed with this exculpatory
    evidence, the trial court “concluded that the testimony of the
    victim and her mother [implicating Gage] was not credible,
    leaving insufficient evidence to support the jury’s verdict.”
    Id. The court thereby vacated Gage’s conviction. Id.
    After the California Court of Appeal reinstated the
    conviction and sentenced Gage to seventy years, Gage ran
    his appeals up through the state courts, arguing that the
    State’s failure to turn over the victim’s medical records
    violated Brady. Id. The state courts rejected Gage’s appeals.
    Id. Gage eventually filed a pro se habeas petition in federal
    district court. Id. at 1164. Curiously, Gage did not press his
    Brady claim in the federal proceeding. Id. at 1163–64. The
    district court denied the petition, which a panel of this court
    upheld. Id. at 1164.
    22                    BROWN V. MUNIZ
    Years later, Gage sought this court’s permission to file a
    second-in-time habeas petition to assert his Brady claim. Id.
    A panel of this court rejected Gage’s argument that the
    petition fell under the Panetti exception. Id. at 1165. The
    court held that Buenrostro “foreclose[d] Gage’s argument,”
    reasoning that, unlike the petitioner’s Ford claim in Panetti,
    the factual predicate for Gage’s Brady claim “existed at the
    time of [Gage’s] first habeas petition.” Id. More
    specifically, Gage determined that
    [t]he factual predicate for Gage’s Brady
    claim developed, at the latest, when the state
    trial judge commented on the contents of [the
    victim’s] medical records . . . . This is not a
    case where the basis for the would-be
    petitioner’s second petition did not exist or
    was unripe when the first petition was filed.
    Id. at 1165.
    Critically, the court found only that the factual predicate
    for Gage’s Brady claim accrued “at the latest[] when the
    state trial judge commented on the contents of [the victim’s]
    medical records.” Id. (emphasis added). The court left open
    the question of when a factual predicate actually accrues for
    purposes of a Brady claim. That question is squarely
    presented here because the alleged Brady material was
    completely unknown to Brown and his counsel at the time of
    trial. Whereas Gage had knowledge of the Brady evidence
    when he filed his initial habeas petition, Brown was
    completely in the dark when he filed his own.
    Today, we answer the question left open by Gage. We
    conclude that a factual predicate accrues at the time the
    constitutional claim ripens—i.e., when the constitutional
    violation occurs. See Panetti, 
    551 U.S. at 945
    ; Magwood,
    BROWN V. MUNIZ                                 23
    
    561 U.S. at
    335 n.11. In the case of a Brady claim, the
    violation occurs at the time the State should have disclosed
    the exculpatory evidence—i.e., before trial. 8 If the factual
    predicate accrues before a petitioner brings an initial federal
    habeas petition, then any subsequent federal petition raising
    a claim based on that factual predicate is second or
    successive and is governed by § 2244(b). Our conclusion is
    compelled by the plain text of § 2244(b), the Supreme
    Court’s decisions in Panetti and Magwood, and our own
    subsequent decision in Buenrostro. 9
    C.
    We observe that our decision in United States v. Lopez,
    
    577 F.3d 1053
    , 1064 (9th Cir. 2009) is in some tension with
    our subsequent decisions in Buenrostro, Gage, and our
    holding today. But Lopez is not controlling because it
    expressly declined to reach the question we answer here.
    8
    To the extent Gage suggested that the factual predicate accrues at
    the time the petitioner learns of it, that case runs afoul of the distinction—
    made clear in Buenrostro—between unripe claims and unknown claims.
    At any rate, because Gage did not hold that the requisite factual predicate
    there did not accrue until the trial judge disclosed the alleged Brady
    material, we need not and do not credit that court’s dicta and instead
    follow Buenrostro’s clear holding to the contrary.
    9
    Our determination aligns the Ninth Circuit with our brethren in the
    Fourth, Tenth, and Eleventh Circuits. In re Pickard, 
    681 F.3d 1201
    ,
    1205 (10th Cir. 2012) (Brady/Giglio claims were “certainly second-or-
    successive . . . because they assert[ed] a basis for relief from the
    underlying convictions”); Tompkins v. Sec’y, Dep’t of Corr., 
    557 F.3d 1257
    , 1259–60 (11th Cir. 2009) (per curiam) (holding that all second-in-
    time habeas petitions based on Brady claims are second or successive);
    Evans v. Smith, 
    220 F.3d 306
    , 323 (4th Cir. 2000) (“the standards that
    Congress has established for the filing of second or successive petitions
    account for precisely the type of situation[—Brady claims—]Evans
    alleges”).
    24                        BROWN V. MUNIZ
    Lopez held that the Brady claim there was, in fact, second or
    successive. 
    Id.
     However, it rested its decision on a finding
    that the evidence underlying the claim was not material. 
    Id.
    The court declined to resolve whether “all second-in-time
    Brady claims”—i.e., material and immaterial claims alike—
    “must satisfy AEDPA’s gatekeeping requirements.” Id.; see
    King v. Trujillo, 
    638 F.3d 726
    , 729 (9th Cir. 2011) (per
    curiam) (recognizing Lopez for the proposition that a Brady
    claim in a second-in-time habeas petition “may not be
    subject to the ‘clear and convincing standard,’ provided the
    newly discovered evidence supporting the claim was
    ‘material’ under Brady” (emphasis in original)).
    We also observe that Lopez’s distinction between
    material and immaterial Brady claims derives from the pre-
    AEDPA abuse-of-the-writ doctrine. Lopez, 
    577 F.3d at 1064
    . While AEDPA’s provisions are inspired by and
    borrow heavily from that judicially-developed rule, see
    Slack, 
    529 U.S. at 486
    , we are bound by AEDPA itself, not
    the judicial standard it superseded. AEDPA § 2244(b)
    makes no distinction based on the materiality of predicate
    facts. Its only concern is with the existence of those facts at
    the time of the initial habeas petition. 10
    10
    Brown’s reliance on Douglas v. Workman, 
    560 F.3d 1156
     (10th
    Cir. 2009), is unavailing. First, it is non-binding extra-circuit precedent.
    Second, Douglas acknowledged that the case was “unusual” and even
    “unique” for several reasons that set it apart from the typical second-in-
    time petition based on a Brady claim. 
    Id. at 1187, 1189
    . Among other
    things, Douglas’ first habeas petition was pending when he discovered
    the Brady evidence. 
    Id. at 1190
    . Because the “first habeas petition had
    never been finally resolved,” the Tenth Circuit deemed the second
    petition not to be second or successive. 
    Id.
     Moreover, in a subsequent
    decision, the Tenth Circuit made clear that it was aligned with its sister
    circuits in deciding that Brady claims are, as a general rule, subject to
    BROWN V. MUNIZ                            25
    D.
    Turning to the matter before us, we first consider
    Brown’s argument that his Brady claims had not ripened at
    the time of his first habeas petition. Brown seeks a rule that
    Brady claims only ripen when a petitioner is on notice of the
    Brady evidence. He relies heavily on our decision in Lopez
    but, as discussed, that case is inapposite. Brown also notes
    that in Magwood, seven justices concluded that a petition is
    not second or successive if the petitioner had no “full and
    fair opportunity to raise” the claim in the first petition. In
    Magwood, those seven justices agreed that, because
    Congress did not define “second or successive,” pre-
    AEDPA abuse-of-the-writ principles are relevant to
    determining whether a second-in-time habeas petition may
    be maintained. Under the abuse-of-the-writ doctrine, “to
    determine whether an application is ‘second or successive,’
    a court must look to the substance of the claim the
    application raises and decide whether the petitioner had a
    full and fair opportunity to raise the claim in the prior
    application.” Magwood, 
    561 U.S. at 346
     (Kennedy, J.,
    dissenting). Because Brown did not know of the Brady
    material at the time of his first petition, he argues that he did
    not have a “full and fair opportunity to raise” his claim at
    that time.
    Brown misreads Magwood. As Justice Kennedy made
    clear in his dissent—which was joined by three other justices
    and commanded a plurality of the Court—a petitioner “had
    no fair opportunity to raise the claim in the prior application”
    if “[1] the claim was not yet ripe at the time of the first
    petition, or [2] where the alleged violation occurred only
    AEDPA’s second or successive bar. In re Pickard, 
    681 F.3d 1201
    , 1205
    (10th Cir. 2012).
    26                    BROWN V. MUNIZ
    after the denial of the first petition.” 
    Id.
     at 345–46 (Kennedy,
    J., dissenting) (internal citation omitted).
    Brown fails to satisfy either prong of Justice Kennedy’s
    disjunctive test. First, the alleged Brady violations occurred
    before Brown sought federal habeas review for the first time,
    and so the “alleged violation” did not occur “after the denial
    of [his] first petition.” Second, contrary to his legal
    contention, Brown’s Brady claim did not ripen only when he
    learned of the alleged Brady material. As discussed,
    whether a claim is ripe under AEDPA turns on whether the
    factual predicate existed, not whether the petitioner knew it
    existed at the time of his initial habeas petition. Buenrostro,
    638 F.3d at 725 (emphasis in original).
    Consistent with the decisions in Panetti, Magwood, and
    Buenrostro, we hold that Brown’s Brady claim was ripe at
    the time of his first habeas petition because the alleged
    constitutional violation—failure to turn over the Hockett,
    Hutchings, and Gin information—occurred before Brown’s
    trial even began. Thus, § 2244(b) applies to Brown’s claim
    and he is entitled to file a second or successive habeas
    petition only if he satisfies that provision’s gatekeeping
    requirements.
    III.
    To make it through the § 2244(b) “gateway,” Brown
    must make a prima facie showing that (1) the purported
    Brady material “could not have been discovered previously
    through the exercise of due diligence,” and (2) that the
    material—if proven on habeas review—establishes by “clear
    and convincing evidence that” Brown is actually innocent.

    Brown makes a prima facie showing as to factor (1).

    Because we agree with the State that Brown fails to make the
    requisite showing as to factor (2), we address only that
    factor.
    A.
    Brown faces an uphill climb straight out of the gate. He
    must show that “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.”
    
    28 U.S.C. § 2244
    (b)(2)(B)(ii) (emphasis added); Lopez, 
    577 F.3d at 1064
    ; see also Cooper v. Woodford, 
    358 F.3d 1117
    ,
    1119 (9th Cir. 2004) (en banc). In other words, Brown must
    do more than simply satisfy the standard for prevailing on
    the underlying constitutional claim. For example, to prevail
    on a straight Brady claim, a petitioner must show that the
    state “suppressed [] evidence, either willfully or
    inadvertently,” that is “favorable to the accused, either
    because it is exculpatory, or because it is impeaching,” and
    which is “material.” Turner v. United States, 
    137 S. Ct. 1885
    , 1893 (2017). “Evidence is material within the
    meaning of Brady when there is a reasonable probability
    that, had the evidence been disclosed, the result of the
    proceeding would have been different.”

     (internal
    quotation marks omitted); Strickler v. Greene, 
    527 U.S. 263
    ,
    280 (1999) (same). Section 2244(b)(2), however, elevates
    the “reasonable probability” standard for Brady materiality
    to a more demanding “clear and convincing evidence”
    standard. Lopez, 
    577 F.3d at 1064
    . Thus, our charge is to
    decide whether the petitioner’s “claim (1) is based on newly
    discovered evidence and [also] (2) establishes that he is
    actually innocent of the crimes alleged,” King, 
    638 F.3d at 730
     (emphasis added)—not whether the petitioner merely
    28                   BROWN V. MUNIZ
    sustained a prejudicial constitutional injury. We have
    observed that “[f]ew applications to file second or successive
    petitions . . . . survive [§ 2244(b)’s] substantive and
    procedural barriers.” Id. (internal citation omitted).
    B.
    Brown argues that the Hockett, Hutchings, and Gin
    information would have “played a significant role in the
    case” because of the weak evidence against him. But Brown
    fails to show how the three officers’ participation in his
    case—which was tangential at best—would have tipped the
    scales in any juror’s mind.
    The record reflects that Hockett’s involvement in
    Brown’s trial had no nexus to any evidence inculpating
    Brown. She was one of the first responders at the crime
    scene and produced a log listing the comings and goings of
    police officers. She offered no testimony and Brown makes
    no assertion that her crime scene log omitted exculpatory
    evidence. Moreover, even if Brown could have impeached
    Hockett with the later-disclosed information, that would not
    have affected the case at all because nothing in the crime
    scene log, nor any actions taken by Hockett, inculpated
    Brown. Thus, the Hockett information does not point to
    Brown’s actual innocence.
    We reach the same result regarding the Hutchings
    material. Like Hockett, Hutchings did not testify at Brown’s
    trial. In fact, Hutchings was not even involved in the
    attempted murder investigation. Instead, he was a defense
    witness in Brown’s case for drug possession. Brown
    inexplicably argues that impeachment evidence against his
    own witness in a separate case would have “weakened the
    credibility of the [attempted murder] investigation.”
    BROWN V. MUNIZ                       29
    Further, the purported Brady material—information that
    Hutchings was charged more than ten years earlier with
    loitering where children congregate, resisting arrest, and
    prostitution—is not material because it bears no relation to
    his credibility in Brown’s case. And, as with Hockett, even
    if Brown could have impeached Hutchings with the
    information, that would not have reasonably affected the
    outcome because Hutchings gathered no evidence
    inculpating Brown.
    Gin had a more substantive role in the attempted murder
    case, but, again, any impeachment evidence is not material.
    While Gin testified at Brown’s trial and produced a report,
    his crime scene interviews with the bus driver and two bus
    passengers were corroborated by live witness testimony.
    Moreover, Gin was not involved in the investigation beyond
    his presence at the crime scene for approximately twenty-to-
    forty minutes, he did not uncover any exculpatory or
    inculpatory evidence, and he had no reason to lie about his
    witness interviews.
    In sum, considering the exculpatory evidence
    individually and together with the evidence presented at
    trial, we hold that Brown fails to make a prima facie showing
    of actual innocence by clear and convincing evidence.
    IV.
    We appreciate that our application of AEDPA’s second
    or successive bar to Brady claims may seem harsh. Why
    should courts saddle petitioners with a stringent standard of
    proof that is a function of the government’s own neglect, or
    worse, malfeasance? The answer is that such is the
    framework Congress established. That a petitioner’s burden
    is higher under these circumstances may seem inequitable,
    but that is a policy, not a legal, objection. Through
    30                   BROWN V. MUNIZ
    § 2244(b), Congress made the legislative choice to prioritize
    state-federal comity and the finality of criminal proceedings
    over affording petitioners multiple opportunities to invoke
    the federal courts’ jurisdiction under the same standard of
    review—a choice that the Supreme Court has definitively
    held to be consistent with the Suspension Clause. Felker v.
    Turpin, 
    518 U.S. 651
    , 664 (1996) (“The added restrictions
    which [AEDPA] places on second habeas petitions are well
    within the compass of th[e] evolutionary process [defining
    the parameters of the writ of habeas corpus], and we hold
    that they do not amount to a ‘suspension’ of the writ contrary
    to Article I, § 9.”). Indeed, the Suspension Clause
    establishes no particular review standard for habeas
    petitions; it does, however, guarantee access to the federal
    courts to press a habeas claim. Section 2244(b) preserves
    this bedrock constitutional right by requiring the court of
    appeals to grant an application for habeas review when clear
    and convincing evidence of actual innocence so requires.
    CONCLUSION
    Petitioner Gregory Brown’s habeas petition alleging
    Brady violations is second or successive because the factual
    predicate underlying his constitutional claim existed at the
    time he filed his first-in-time habeas petition. Under a
    second or successive analysis, his claim fails because the
    underlying facts do not point to—let alone show by clear and
    convincing evidence—his actual innocence. The district
    court’s dismissal of Brown’s habeas petition for failure to
    obtain authorization from this court to file a second or
    successive petition is therefore AFFIRMED, and Brown’s
    application for leave to file a second or successive habeas
    petition is DENIED.
