    OPINION
    _________________
    KAREN NELSON MOORE, Circuit Judge. An Ohio jury convicted Petitioner-Appellant
    Andre Williams of aggravated murder and sentenced him to death. After filing direct appeals
    and seeking post-conviction relief in state and federal courts, Williams filed a post-conviction
    petition in Ohio state court pursuant to Atkins v. Virginia, 
    536 U.S. 304
     (2002), arguing that he is
    ineligible for the death penalty because he is intellectually disabled. The Ohio courts rejected
    Williams’s Atkins petition, and the district court denied Williams’s federal habeas petition. On
    appeal, Williams argues that his trial counsel provided ineffective assistance at the penalty phase
    for failing to obtain a mitigation specialist to explain his intellectual limitations to the jury, and
    he argues that his Atkins petition was improperly denied because he is intellectually disabled.
    For the following reasons, the state court’s application of law with regard to whether Williams is
    intellectually disabled under Atkins was contrary to clearly established Federal law.
    Accordingly, we VACATE and REMAND so that the district court may grant a
    CONDITIONAL WRIT OF HABEAS CORPUS prohibiting Williams’s execution unless the
    State reassesses Williams’s Atkins petition consistent with this opinion.
    I. BACKGROUND
    In 1989, Williams was convicted and sentenced to death for murder. Williams filed
    direct appeals to the Ohio Eleventh District Court of Appeals and the Ohio Supreme Court, both
    of which affirmed imposition of the death penalty. Williams filed his first petition for post-
    conviction relief, raising seven claims, but the trial court denied the petition without conducting
    an evidentiary hearing. On post-conviction appeal, the appellate court affirmed dismissal of
    Williams’s post-conviction petition, and the Ohio Supreme Court declined to exercise
    jurisdiction.
    In his first federal habeas petition, Williams raised thirty-one claims for relief. On March
    28, 2003, the district court denied Williams’s petition. No. 1:99-cv-2399, R. 45 (D. Ct. Mem.
    and Order) (Page ID #68). Relevant here, the court found that Williams’s claim that his trial
    Nos. 03-3626/12-4269                         Williams v. Mitchell                             Page 3
    counsel was ineffective for failing to obtain a mitigation specialist or other mental health
    professional who could have explained his IQ scores and intellectual functioning to the jury was
    procedurally defaulted. Id. at 82 (Page ID #149). But the court noted that Williams may be
    entitled to relief pursuant to Atkins, which was decided after Williams filed his federal habeas
    petition and which held that execution of mentally retarded individuals violates the Eighth
    Amendment’s ban on cruel and unusual punishments.1 Id. at 84‒85 (Page ID #151‒52). The
    district court declined to issue a certificate of appealability as to any of Williams’s claims. Id. at
    117 (Page ID #184). Williams filed a notice of appeal, and we granted Williams’s motion to stay
    and hold the case in abeyance to allow him to pursue his Atkins claim in state court. See No. 03-
    3626, R. 16 (6/27/03 Letter); No. 09-3898, R. 8 (9/28/09 Order).
    Williams then filed a post-conviction petition in Trumbull County, Ohio, Court of
    Common Pleas on June 9, 2003 asserting that his death sentence should be nullified because he
    is intellectually disabled pursuant to Atkins and the Ohio Supreme Court’s decision State v. Lott,
    
    779 N.E.2d 1011
     (Ohio 2002), which set forth Ohio’s standards for determining intellectual
    disability pursuant to Atkins. Appendix to Appellant Br. (“Appx.”) at A-1 (Atkins Petition at 1).
    In his five-page petition, Williams asserted that the state trial court should find him intellectually
    disabled based on collateral estoppel on the grounds that the Ohio Supreme Court and this court
    have already determined him intellectually disabled, or by taking judicial notice of the trial
    proceedings. 
    Id.
     at A-1‒4 (Atkins Petition at 1‒4). In the alternative, Williams requested an
    evidentiary hearing and sought leave to conduct discovery and funds for an expert. 
    Id.
     at A-4
    (Atkins Petition at 4). Williams attached to his petition an affidavit from his cousin, Stacey Vail,
    who noted Williams’s deficiencies in mental capacity and adaptive skills up until his
    incarceration in 1989 when Williams was twenty-one years old. Appx. at A-6 (Ex. A to Atkins
    Petition).
    In response to Williams’s petition, the State of Ohio filed a motion to dismiss the petition
    and/or motion for summary judgment. Appx. at A-14 (State’s Mot. to Dismiss and/or SJ). The
    state attached over 170 pages of exhibits to its motion. 
    Id.
     at A-50‒221 (Exs. to State’s Mot. to
    1
    Recent judicial opinions and the professional community have adopted the contemporary term
    “intellectual disability” rather than “mental retardation.” We adopt for our present analysis the term “intellectual
    disability.” But where quoting and discussing previous opinions and reports that employed the term “mental
    retardation,” we will employ the old term for clarity of reference.
    Nos. 03-3626/12-4269                   Williams v. Mitchell                     Page 4
    Dismiss and/or SJ). In response to the state’s motion, Williams filed a “Motion Opposing
    Judgment” in which he again argued that a hearing was necessary to adjudicate fairly his
    petition. Appx. at A-241 (Williams Mot. Opp. Judgment). Along with his motion, Williams
    filed school records and psychological reports, which indicated, among other things, that at the
    age of fifteen Williams had a full-scale IQ score of 67 and the “social age” of a “nine year old
    with deficiencies in communication, locomotion, occupation and self-direction,” Appx. at A-
    271‒72 (8/31/83 Psychologist Rep. at 2‒3), along with his full prison record. Williams also
    attached a three-page “Preliminary Psychological Evaluation” dated December 9, 2003 from Dr.
    James Eisenberg, in which Dr. Eisenberg gave his “preliminary opinion” that Williams “d[id] not
    currently meet the criteria for a diagnosis of mental retardation based on the Lott definition”
    given his full-scale IQ of 75 per the Wechsler Adult Scale of Intelligence. Appx. at A-253‒55
    (Eisenberg Prelim. Rep. at 1‒3).
    Based on this record, the state trial court granted the state’s motion for summary
    judgment without a holding an evidentiary hearing, finding Williams failed to present sufficient
    evidence to meet the three-factor “Atkins/Lott test.” Appx. at A-284‒291 (10/19/04 Tr. Ct. Op.
    at 6‒13).   The Ohio Court of Appeals reversed this decision, holding that the trial court
    impermissibly weighed conflicting evidence, made findings of fact, and relied on
    “unauthenticated documents submitted by the state that were allegedly handwritten or typed by
    Williams,” and remanded to the trial court. State v. Williams, 
    847 N.E.2d 495
    , 499‒500 (Ohio
    Ct. App. 2006). On remand, the trial court again granted summary judgment without holding an
    evidentiary hearing, again finding Williams failed to present sufficient evidence to meet any of
    the three factors under the Atkins/Lott test. Appx. at A-309 (9/11/07 Tr. Ct. Op.). In doing so,
    the trial court relied largely on the same grounds as in its prior opinion—it gave little weight to
    or disregarded evidence favoring Williams, while crediting evidence presented by the state. See
    
    id.
     at A-322‒33 (9/11/07 Tr. Ct. Op. at 14‒25).
    This time, the Ohio Court of Appeals affirmed the dismissal of Williams’s petition,
    though it did not accept the trial court’s reasoning. State v. Williams, No. 2007-T-0105, 
    2008 WL 2582849
     (Ohio Ct. App. June 27, 2008). Relying on evidence that the trial court gave little
    weight or disregarded (e.g., IQ score of 67 and Vail Affidavit, see Appx. at A-322‒25 (9/11/07
    Nos. 03-3626/12-4269                          Williams v. Mitchell                              Page 5
    Tr. Ct. Op. at 14‒17)), the court held that Williams met his burden under the third Lott factor—
    onset of intellectual disability before the age of eighteen. Williams, 
    2008 WL 2582849
    , at *5‒6.
    But the appellate court determined that Williams failed to meet the first two Lott factors—
    “(1) significantly subaverage intellectual functioning[] [and] (2) significant limitations in two or
    more adaptive skills.” Id. at *5 (quoting Lott, 779 N.E.2d at 1014). The court rested on the fact
    that these two criteria apply only to Williams’s “present functioning,” and evidence of
    Williams’s intellectual functioning and adaptive skills earlier in his life “do not constitute
    competent evidence from which inferences may be made regarding his present mental capacity.”
    Id. at *6. After rejecting this evidence, the court held that the sole remaining evidence put forth
    by Williams—the IQ of 75 in Eisenberg’s preliminary report—failed to show that Williams is
    mentally retarded, and so summary judgment for the state was proper. Id. The court also held
    that evidence of the underlying crimes and prison records indicated that Williams did not have
    current limitations in adaptive skills. Id.2
    The Ohio Supreme Court declined jurisdiction. Appx. at A-352 (Ohio Sup. Ct. Entry).
    Williams then filed a second federal habeas petition, arguing that he is ineligible for the death
    penalty because he is mentally retarded under Atkins. No. 1:09-cv-2246, R. 6 (Pet. for Writ of
    Habeas Corpus) (Page ID #177). The federal district court denied Williams’s petition under
    
    28 U.S.C. § 2254
    . No. 1:09-cv-2246, R. 36 (D. Ct. Opinion) (Page ID #741). In doing so, the
    district court held that “it was not unreasonable” for the state appellate court to exclude the pre-
    1989 evidence from its analysis of the first two Lott factors. Id. at 58 (Page ID #798). The
    district court also denied Williams’s request for discovery and an evidentiary hearing. See No.
    1:09-cv-2246, R. 27 (D. Ct. Opinion) (Page ID #614). This appeal followed.
    2
    No other member of the three-judge court of appeals panel joined the lead opinion’s analysis. Judge
    Trapp concurred in judgment only and wrote a separate opinion asserting that abuse of discretion is the correct
    standard of review, rather than the de novo standard applied by the lead opinion’s author, Judge Grendell. Judge
    O’Toole filed a dissenting opinion in which she found that “it is clear that Atkins, Lott, and White and their progeny
    as well as the U.S. and Ohio constitutions require an evidentiary hearing to determine the issue of [Williams’s]
    retardation.” Williams, 
    2008 WL 2582849
    , at *9. We treat Judge Grendell’s lead opinion as operative, given that it
    is the only opinion offering substantive analysis to support the court of appeals’s decision. Because our resolution
    of this appeal does not turn on the proper standard of review, we do not address this issue.
    Nos. 03-3626/12-4269                   Williams v. Mitchell                      Page 6
    II. STANDARD OF REVIEW
    In a federal habeas corpus proceeding, “we review the district court’s legal conclusions
    de novo and its factual findings for clear error.” Hanna v. Ishee, 
    694 F.3d 596
    , 605 (6th Cir.
    2012). Under the Antiterrorism and Effective Death Penalty Act (AEDPA), a writ of habeas
    corpus may not be granted unless the state court’s adjudication of the claim on the merits
    “(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 state court’s
    decision is “contrary to” clearly established Federal law if it “applies a rule that contradicts the
    governing law set forth in [Supreme Court] cases” or if it “confronts a set of facts that are
    materially indistinguishable from a decision of [the Supreme] Court and nevertheless arrives at a
    result different from [this] precedent.” Williams v. Taylor, 
    529 U.S. 362
    , 405‒06 (2000). A state
    court’s decision is an “unreasonable application” of clearly established Federal law if it
    “correctly identifies the governing legal rule but applies it unreasonably to the facts of a
    particular prisoner’s case.”   
    Id.
     at 407–08.     Under § 2254(d)(1)’s unreasonable-application
    clause, the critical point is whether “it is so obvious that a clearly established rule applies to a
    given set of facts that there could be no ‘fairminded disagreement’ on the question.” White v.
    Woodall, 
    134 S. Ct. 1697
    , 1706‒07 (2014) (quoting Harrington v. Richter, 
    562 U.S. 86
    , 103
    (2011)).
    The phrase “clearly established Federal law” in § 2254(d)(1) “refers to the holdings, as
    opposed to the dicta, of [the Supreme] Court’s decisions as of the time of the relevant state-court
    decision.” Williams, 
    529 U.S. at 412
    . But “because Atkins reserved for the states the task of
    developing appropriate ways to enforce the constitutional restriction” prohibiting the execution
    of the intellectually disabled, “federal courts conducting habeas review routinely look to state
    law that has been issued after the defendant’s state conviction has become final in order to
    determine how Atkins applies to the specific case at hand.” Black v. Bell, 
    664 F.3d 81
    , 92
    (6th Cir. 2011) (internal quotation marks omitted). This means that where a state-court decision
    is “contrary to” clearly established state supreme court precedent applying Atkins, the decision is
    Nos. 03-3626/12-4269                    Williams v. Mitchell                      Page 7
    “contrary to Atkins” for purposes of habeas review. 
    Id.
     at 96‒97. Thus, in the Atkins context,
    “clearly established governing law” refers to the Supreme Court decisions and controlling state
    law decisions applying Atkins. See Van Tran v. Colson, 
    764 F.3d 594
    , 617‒19 (6th Cir. 2014)
    (holding that the Tennessee state court’s Atkins determination was “contrary to clearly
    established governing law” as set forth in Tennessee Supreme Court precedent applying Atkins).
    In determining whether to grant a petitioner habeas relief, a federal court must “review the last
    state court decision adjudicated on the merits.” Gagne v. Booker, 
    680 F.3d 493
    , 511‒12 (6th
    Cir.), cert. denied, 
    133 S. Ct. 481
     (2012).
    III. ANALYSIS
    On appeal, Williams raises three issues for review. First, Williams argues that his trial
    counsel was ineffective at the penalty phase for failing to obtain a mitigation specialist to explain
    his intellectual limitations. Second, Williams claims that the Ohio state court’s dismissal of his
    Atkins petition was contrary to and/or an unreasonable application of clearly established Federal
    law or an unreasonable determination of the facts under 
    28 U.S.C. § 2254
    (d)(1)‒(2). Finally,
    Williams argues that the federal district court improperly denied discovery and an evidentiary
    hearing. We address each issue in turn.
    A.     Williams’s Claim of Ineffective Assistance of Trial Counsel Is Procedurally
    Defaulted
    We first address Williams’s claim that his trial counsel provided constitutionally
    ineffective assistance at the penalty phase by filing to obtain a mitigation specialist to explain to
    the jury the significance of his intellectual deficiencies. The district court found this claim
    procedurally defaulted. We agree.
    We review a district court’s determination that a claim is procedurally defaulted de novo.
    Carter v. Mitchell, 
    693 F.3d 555
    , 563 (6th Cir. 2012). “[A] petitioner may procedurally default a
    claim by failing to raise a claim in state court, and pursue that claim through the state’s ‘ordinary
    appellate review procedures.’” Williams v. Anderson, 
    460 F.3d 789
    , 806 (6th Cir. 2006) (quoting
    O’Sullivan v. Boerckel, 
    526 U.S. 838
    , 847 (1999)). To avoid procedural default, the petitioner
    must “exhaust” all state-court remedies. Carter, 693 F.3d at 563‒64. Exhaustion requires “fair
    presentation” of the federal claim “to the state courts, including the state court of appeals and the
    Nos. 03-3626/12-4269                    Williams v. Mitchell                       Page 8
    state supreme court.” Bray v. Andrews, 
    640 F.3d 731
    , 734‒35 (6th Cir. 2011) (brackets omitted);
    see O’Sullivan, 
    526 U.S. at 845
     (“[S]tate prisoners must give the state courts one full opportunity
    to resolve any constitutional issues by invoking one complete round of the State’s established
    appellate review process.”). To fairly present a federal claim, a state prisoner is required to
    present the state courts with “both the legal and factual basis” for the claim. Anderson, 
    460 F.3d at 806
     (emphasis in original). “If a prisoner failed to exhaust his or her state court remedies and
    state law would no longer permit the petitioner to raise the claim when he or she files a petition
    for habeas relief in federal court, the claim is procedurally defaulted.” Carter, 693 F.3d at 564.
    A petitioner may overcome default by showing “cause” and “prejudice” for failing to exhaust.
    Id.
    Williams argues on appeal that his trial counsel was ineffective at the penalty phase for
    “fail[ing] to obtain a mitigation specialist or other mental health professional who could have
    explained his borderline mental retardation and learning disabilities to the jury.” Appellant Br. at
    68. On direct appeal to the Ohio Court of Appeals, Williams fairly presented this claim—in his
    Thirteenth Assignment of Error, he argued that he was denied effective assistance of counsel at
    the penalty phase in violation of the United States Constitution because his counsel failed to
    offer expert testimony to explain the significance of his low IQ scores and mental defects.
    Supplemental Appendix to Appellee Br. (“Supp. Appx.”) at 915‒18 (Williams 9/16/91 Ohio Ct.
    App. Br. at 52‒55). But after the Ohio Court of Appeals rejected this argument on the merits,
    Supp. Appx. at 1032‒33 (3/27/95 Ohio Ct. App. Op. at 63‒64), Williams failed to raise the claim
    to the Ohio Supreme Court on direct appeal. See Supp. Appx. at 1088 (Williams 6/26/95 Ohio
    Sup. Ct. Br.).
    Williams also failed to present this claim throughout his state post-conviction appeal. In
    his initial post-conviction petition, Williams argued that he received ineffective assistance of
    counsel under federal law because, among other things: his counsel failed to investigate his
    medical history and the reasons for a drop in his IQ from 1978 to 1983, Supp. Appx. at 1198‒99
    (Williams Post-Conv. Pet. at 29‒30); his counsel failed to begin preparing for the penalty phase
    until after the verdict in the guilt phase of the trial, id.; the trial court denied Williams the funds
    to present an expert to testify about his intellectual capabilities, id. at 1199‒1203 (Williams Post-
    Nos. 03-3626/12-4269                    Williams v. Mitchell                      Page 9
    Conv. Pet. at 30‒34); and his “trial counsel failed to investigate or raise these matters” in
    violation of federal law, id. at 1209 (Williams Post-Conv. Pet. at 40). In support, Williams
    attached to his petition affidavits from criminal defense attorneys with experience trying capital
    murder cases who attested that an expert was necessary to effectively gather mitigating evidence
    during the penalty phase, and Williams was prejudiced by his counsel’s failure to present
    evidence from a psychologist or psychiatrist at trial. Id. at 1240, 1244 (Ex. E to Williams Post-
    Conv. Pet.; Ex. G to Williams Post-Conv. Pet.); see also Supp. Appx. at 1248 (Williams Mem. in
    Supp. of Mot. for Expert Funds at 1) (asserting in a subsequent motion for funds to hire an expert
    for post-conviction proceedings that Williams’s trial counsel was ineffective under federal law
    for “fail[ure] to secure a neuropsychologist to determine the effect of head injuries and repeated
    blackouts on the Petitioner’s neurological functioning.”).
    The post-conviction trial court rejected these claims. In doing so, the court noted that
    Williams raised the same ineffective-assistance claims on direct appeal in his Thirteenth
    Assignment of Error. Supp. Appx. at 1271 (Find. of Fact and Concl. of Law). The court further
    noted that Williams supported his claim of ineffective assistance of counsel through affidavits,
    one of which argued that Williams’s trial counsel was ineffective for failing to obtain an expert
    to assist in the preparation and presentation of mitigating evidence at the penalty phase of trial.
    Id. at 1272 (Find. of Fact and Concl. of Law). But the court rejected this affidavit as a
    “statement[] of opinion” rather than a “statement[] of operative ‘facts’” and, consequently, found
    that Williams failed to raise sufficient facts to demonstrate lack of effective counsel and resultant
    prejudice. Id. at 1273 (Find. of Fact and Concl. of Law). Based on this, the claim of ineffective
    assistance of counsel that Williams asserts here—that his trial counsel was ineffective for failing
    to present a mitigation expert at the penalty phase—was fairly presented to the state post-
    conviction trial court.
    But then Williams failed to present this claim throughout “the State’s established
    appellate review process.” O’Sullivan, 
    526 U.S. at 845
    . In his initial post-conviction appeal,
    Williams argued that the jury should have heard all mitigation evidence and that his trial counsel
    was ineffective under federal law for failing to “investigate possible mitigating factors by
    making a thorough review of the Petitioner’s background,” citing his history of blackouts and
    Nos. 03-3626/12-4269                    Williams v. Mitchell                     Page 10
    low IQ scores and his counsel’s failure to prepare adequately for the penalty phase of trial as
    support. Supp. Appx. at 1297‒99 (Williams 10/27/97 Ohio Ct. App. Br. at 12‒14). The court of
    appeals rejected his ineffective-assistance claim based on res judicata on the grounds that the
    affidavits supporting the claim were based on opinion and evidence of Williams’s declining IQ
    was introduced at the penalty phase of trial. Supp. Appx. at 1331‒32 (10/19/98 Ohio Ct. App.
    Op. at 6‒7). Then, Williams’s post-conviction brief to the Ohio Supreme Court stated flatly,
    without citation to legal authority: “[t]he petition also alleged that Appellant experienced a
    10 point IQ drop in a few short years, that trial counsel did nothing about this potential
    mitigation evidence except to call a school counselor at trial; that the drop was indicative of the
    possibility of organic brain damage; and that it was ineffective assistance of counsel to fail to
    pursue such a matter.” Id. at 1348 (Williams 11/30/98 Ohio Sup. Ct. Br. at 9) (footnote omitted).
    The Ohio Supreme Court declined jurisdiction. State v. Williams, 
    706 N.E.2d 788
     (Ohio Mar. 3,
    1999).
    Nowhere does Williams even suggest in his post-conviction appellate filings that his trial
    counsel was ineffective at the penalty phase for failing to present a mitigation specialist to
    explain his low IQ scores. Williams’s general reference to his trial counsel’s failure to “pursue”
    his intellectual limitations at trial, as asserted in his brief to the Ohio Supreme Court, is not the
    same as setting forth the factual and legal underpinnings for the claim he advances now—that his
    trial counsel should have presented expert assistance at the penalty phase to explain his low
    intellectual functioning to the jury, and that his counsel’s failure to do so caused him prejudice
    under the United States Constitution. Indeed, Williams makes no reference whatsoever in his
    Ohio Supreme Court briefing to his counsel’s ineffectiveness for failing to present an expert at
    trial. The Ohio Supreme Court was thus unable to assess the facts and the law bearing on his
    constitutional claim, and, consequently, Williams failed to exhaust the claim.
    Nor does Williams show “cause” for his failure to exhaust. Carter, 693 F.3d at 564.
    Williams’s sole argument on this score is that under Martinez v. Ryan, 
    132 S. Ct. 1309
     (2012),
    his post-conviction counsel’s ineffectiveness serves as cause for Williams’s failure to raise his
    claim that his trial counsel was ineffective for failing to present an expert at the penalty phase.
    In Martinez, the Court created an exception to the general rule that ineffective assistance in a
    Nos. 03-3626/12-4269                     Williams v. Mitchell                    Page 11
    post-conviction proceeding does not establish cause for a procedural default. As the Court
    explained in Trevino v. Thaler, Martinez held that procedural default can be excused for cause
    where:
    (1) the claim of “ineffective assistance of trial counsel” was a “substantial” claim;
    (2) the “cause” consisted of there being “no counsel” or only “ineffective”
    counsel during the state collateral review proceeding; (3) the state collateral
    review proceeding was the “initial” review proceeding in respect to the
    “ineffective-assistance-of-trial-counsel claim”; and (4) state law requires that an
    “ineffective assistance of trial counsel [claim] . . . be raised in an initial-review
    collateral proceeding.”
    Trevino v. Thaler, 
    133 S. Ct. 1911
    , 1918 (2013) (emphasis in original) (quoting Martinez, 
    132 S. Ct. at
    1318–19, 1320‒21). In Trevino, the Court modified the fourth element to apply to
    situations where state law makes it “highly unlikely” that a defendant will have a “meaningful
    opportunity” to raise ineffective-assistance claims on direct appeal. Id. at 1921.
    We have held that Martinez does not apply in Ohio because Ohio permits ineffective-
    assistance-of-trial-counsel claims on direct appeal—making the exception inapplicable under the
    fourth prong of the Martinez framework—and have questioned whether Trevino applies in Ohio
    based on that prong. See Henness v. Bagley, 
    766 F.3d 550
    , 557 (6th Cir. 2014) (mentioning
    issue) (citing McGuire v. Warden, Chillicothe Corr. Inst., 
    738 F.3d 741
    , 750 (6th Cir. 2013),
    cert. denied, McGuire v. Robinson, 
    134 S. Ct. 998
     (2014)). But we again need not decide the
    applicability of Trevino in Ohio based on the fourth prong because Williams fails to satisfy the
    third prong of the Martinez/Trevino framework—as set forth above, his counsel did raise the
    claim of ineffective assistance of trial counsel that he pursues here at the initial-review post-
    conviction proceedings, yet failed to raise it on post-conviction appeal through to the Ohio
    Supreme Court. The Martinez/Trevino exception is thus inapplicable because it “does not extend
    to attorney errors in any proceeding beyond the first occasion the State allows a prisoner to raise
    a claim of ineffective assistance at trial.” Martinez, 
    132 S. Ct. at 1320
    ; Wallace v. Sexton, 570 F.
    App’x 443, 453 (6th Cir. 2014) (holding “ineffective assistance of [the petitioner’s] post-
    conviction appellate counsel is not cause to excuse the procedural default” under Martinez).
    As a result, Williams has failed to establish cause for failing to exhaust the claim of
    ineffective assistance of trial counsel that he pursues here, and because he can no longer raise
    Nos. 03-3626/12-4269                    Williams v. Mitchell                    Page 12
    this claim in Ohio state court, see OHIO REV. CODE § 2953.23(A)(1), it is procedurally defaulted.
    Carter, 693 F.3d at 563‒64.
    B.     The Operative Ohio Court Decision Dismissing Williams’s Atkins Petition Is
    Contrary to Clearly Established Federal Law
    Williams next claims that the Ohio state court’s dismissal of his Atkins petition was
    contrary to and/or an unreasonable application of clearly established Federal law or an
    unreasonable determination of the facts under 
    28 U.S.C. § 2254
    (d)(1)‒(2).            In Atkins, the
    Supreme Court held that execution of intellectually disabled individuals violates the Eighth
    Amendment’s ban on cruel and unusual punishments. 
    536 U.S. 304
    . In doing so, the Court left
    to the states “‘the task of developing appropriate ways to enforce the constitutional restriction
    upon [their] execution of sentences.’” 
    Id. at 317
     (quoting Ford v. Wainwright, 
    477 U.S. 399
    ,
    416‒17 (1986)). The Court did, however, cite with approval clinical definitions of intellectual
    disability from the American Association on Mental Retardation (“AAMR”) and the American
    Psychiatric Association (“APA”). See 
    id.
     at 308 n.3, 318. Relevant here, the AAMR’s definition
    stated that: “Mental retardation refers to substantial limitations in present functioning. It is
    characterized by significantly subaverage intellectual functioning, existing concurrently with
    related limitations in two or more . . . applicable adaptive skill areas . . . . Mental retardation
    manifests before age 18.” 
    Id.
     at 308 n.3.
    In response to Atkins, the Ohio Supreme Court set forth in State v. Lott the Ohio
    standards for determining intellectual disability. 
    779 N.E.2d 1011
    , 1014 (Ohio 2002). Adopting
    the clinical definitions cited with approval in Atkins, the Lott court defined mental retardation as:
    “(1) significantly subaverage intellectual functioning, (2) significant limitations in two or more
    adaptive skills, such as communication, self-care, and self-direction, and (3) onset before the age
    of 18.” Lott, 779 N.E.2d at 1014. The Lott court did not limit the evidence that a party could
    submit to establish mental retardation under the three-factor test. To the contrary, in applying
    this definition to the facts, the Lott court held that an IQ score of 72 (but within the “five-point
    margin of error on any IQ test score”) from 1986 and affidavits from family members and friends
    regarding “personality problems and behavioral indicators of early-life trauma,” which indicated
    that he is mentally retarded; and IQ scores of 77‒81 and 83‒91, an IQ score of 87‒97 from when
    the petitioner was in the sixth grade, and an IQ score of 86 from 1984, which indicated that he is
    Nos. 03-3626/12-4269                         Williams v. Mitchell                          Page 13
    not mentally retarded, created questions of fact as to whether the petitioner met the Ohio
    definition of mental retardation. Id. at 1013‒14. The Lott court thus determined that twenty-
    year-old evidence of the petitioner’s intellectual capabilities and adaptive skills was relevant to
    whether the petitioner met the newly created three-part test for intellectual disability in Ohio and
    remanded the case so that the trial court could resolve the factual dispute. Id.
    Here, the last state-court decision adjudicated on the merits—the June 27, 2008 Ohio
    Court of Appeals opinion—assessed whether Williams offered sufficient factual support for his
    Atkins petition under the three Lott factors. Williams, 
    2008 WL 2582849
    , at *5 (quoting Lott,
    779 N.E.2d at 1014). The Ohio Court of Appeals ruled that Williams satisfied the third Lott
    factor because the evidence indicated that he was intellectually disabled before turning eighteen
    years of age. In doing so, unlike the trial court, the court of appeals credited Williams’s full
    scale IQ score of 67 from the age of fifteen, school and psychological records, and an affidavit
    from his cousin as competent evidence of intellectual disability under the third Lott factor. Id. at
    *5‒6. But the court categorically rejected this evidence in assessing whether Williams satisfied
    the first two Lott factors. The court held that because “the definition of retardation adopted by
    Lott contemplates ‘substantial limitations in present functioning,’” evidence of Williams’s
    adaptive skills and functioning prior to 1989 “d[id] not constitute competent evidence from
    which inferences may be made regarding his present mental capacity.” Id. at *6 (emphasis in
    original). Essentially, the court of appeals held that, based on Lott, it could not consider
    evidence of Williams’s intellectual functioning and adaptive skills from before 1989 as
    competent evidence of his “present functioning” as a matter of law. Based on this, the court
    affirmed summary judgment for the state on Williams’s Atkins petition.3
    We hold that the court of appeals’s decision was contrary to clearly established Federal
    law for a number of reasons. First, the Ohio Court of Appeals’s refusal to consider past
    evidence of intellectual disability in determining whether Williams has significantly subaverage
    mental functioning and adaptive skills limitations is directly contrary to the clearly established
    governing law set forth in Atkins/Lott. Here, the court of appeals was faced with an evidentiary
    record materially similar to Lott—an almost twenty-year-old IQ score of 67 from when Williams
    3
    Again, the description of the Ohio Court of Appeals’s rationale applies only to Judge Grendell’s opinion;
    Judge Trapp concurred in the judgment only, and Judge O’Toole dissented. See supra n.2.
    Nos. 03-3626/12-4269                    Williams v. Mitchell                     Page 14
    was fifteen years old, evidence of limitations in adaptive skills from school and psychological
    records, and an affidavit setting forth Williams’s intellectual limitations up to his incarceration at
    the age of twenty-one in 1989 (among others), on the one hand; and a more recent IQ score of
    75 from Dr. Eisenberg’s preliminary report and fifteen years of prison records, on the other.
    Yet, notwithstanding the Lott court holding that past evidence of intellectual functioning (e.g.,
    past IQ scores, evidence of adaptive limitations from “early-life”) was relevant to the three
    Atkins factors, the court of appeals rejected outright any pre-1989 evidence from its analysis of
    Williams’s intellectual functioning and adaptive skills, despite finding this same evidence
    showed that Williams was intellectually disabled before he turned eighteen. The Ohio Court of
    Appeals thus refused even to consider—as a matter of law—the exact same type of evidence that
    created a factual dispute in Lott. Had the Lott court applied the court of appeals’s analysis, it
    would have found no factual dispute because the only evidence suggesting present intellectual
    disability was Lott’s 1986 IQ score and affidavits from family and friends that presumably
    depended on observation of Lott’s pre-incarceration functioning. 779 N.E.2d at 1013. By
    rejecting past evidence of intellectual deficiencies wholesale, the Ohio Court of Appeals reached
    a decision opposite to the clearly established Federal law set forth in Atkins/Lott. See Williams,
    
    529 U.S. at 405
    ; see also Van Tran, 764 F.3d at 617‒18 (looking to governing state law in
    determining that the state court’s decision at issue was “contrary to clearly established Federal
    law” in the Atkins context); Black, 664 F.3d at 96‒97 (holding the Tennessee court’s failure to
    consider evidence supporting a finding of mental retardation “contrary to the latest Tennessee
    Supreme Court’s decision on this subject” and thus “contrary to Atkins”).
    That Williams’s low IQ scores date from when he was a minor does not adequately
    distinguish this case from Lott, in which there is no indication of Lott’s age in 1986, when his IQ
    was measured as 72. In support of its decision that evidence of Williams’s childhood intellectual
    disability is not competent evidence for Williams’s present intellectual capacity, the Ohio Court
    of Appeals cited the Florida Supreme Court’s report of an expert’s testimony regarding
    developmental delays. That expert testified that “‘because mental retardation is lifelong, a child
    may meet the criteria for the diagnosis because of developmental delays without being mentally
    retarded. . . . Thus, diagnosis of mental retardation in an adult must be based on present or
    current intellectual functioning and adaptive skills and information that the condition also existed
    Nos. 03-3626/12-4269                    Williams v. Mitchell                  Page 15
    in childhood.’” Williams, 
    2008 WL 2582849
    , at *6 (quoting Jones v. State, 
    966 So.2d 319
    , 327
    (Fla. 2007)). But the expert’s testimony focused on limitations in adaptive skills, not IQ scores.
    See Jones, 966 So.2d at 327 (noting that expert’s testimony was based on clinical authority
    stating that in some circumstances young children who show signs of mild mental retardation
    based on “failure in academic learning tasks” may no longer meet the clinical definition as they
    mature because they “develop good adaptive skills in other domains” through training)
    (emphasis added). Moreover, contrary to the Ohio Court of Appeals’s decision here, the Jones
    court held that the expert properly considered evidence from throughout the appellant’s life in
    assessing his adaptive functioning, reviewing the appellant’s records from childhood up until the
    hearing to determine his current functioning. 
    Id.
     at 327‒28. In any event, even when applied to
    IQ scores, the expert testimony quoted above merely suggests that an IQ score obtained when an
    individual is a minor may in some circumstances be given less weight than an adult IQ score, but
    not no weight. A determination that an individual either suffered from developmental delays or
    is intellectually disabled excludes the possibility that the individual is neither intellectually
    disabled nor suffered from developmental delays and thus tends to increase the likelihood (albeit
    perhaps only somewhat) that the individual is intellectually disabled. Further, the probative
    force of such evidence depends on whether the low childhood IQ scores are the result of lifelong
    intellectual disability rather than developmental delays. Jones is silent on this question, and
    there is no basis for the Ohio Court of Appeals to have assumed, as it apparently did, that most
    low childhood IQ scores (or, to be precise, age-fifteen IQ scores) are the result of developmental
    delays. The Ohio Court of Appeals’s determination that Williams’s age-fifteen IQ score was not
    competent evidence to show present intellectual limitations was thus an unreasonable application
    of Lott.
    The Ohio Court of Appeals also cited State v. White, 
    885 N.E.2d 905
     (Ohio 2008), and
    State v. Lorraine, No. 2006-T-0100, 
    2007 WL 4376250
     (Ohio Ct. App. Dec. 14, 2007), to
    support its decision to exclude this evidence from its analysis—but neither case supports its
    holding. In White, the Ohio Supreme Court simply quoted the “present functioning” language in
    the AAMR’s definition of mental retardation (quoted above) from Atkins in setting forth the
    background that led to Lott’s definition of intellectual disability.     885 N.E.2d at 907‒08.
    Nowhere did it suggest that the “present functioning” language controlled or in any way limited
    Nos. 03-3626/12-4269                    Williams v. Mitchell                    Page 16
    the evidence that could be presented to support the first two Lott factors. To the contrary, the
    White court recognized that intellectual disability must “manifest before age 18” and credited
    evidence establishing that “a person’s mental-retardation status does not change over his
    lifetime.” Id. at 908, 917. For these reasons, the White court held that the trial court abused its
    discretion in denying the petitioner’s Atkins petition because “if an adult is found to have
    intellectual and adaptive deficits not caused by a brain injury or illness, it can be inferred that
    those deficits have existed since childhood.” Id. (emphasis added). The White court thus
    recognized that because intellectual disability manifests itself during childhood and remains
    static throughout life, evidence of intellectual disability from one point in life is relevant to an
    examination of intellectual disability in another. That developmental delays may account for
    some low IQ scores in juveniles does not automatically eliminate the relevance of juvenile IQ
    scores to a determination of adult intellectual capacity.
    Similarly, Lorraine expressly rejected the Ohio Court of Appeals’s reading of “present
    functioning” in this case—it explained that “[t]he trial court should not have couched the inquiry
    in terms of ‘present mental status,’” yet it recognized that “the question of a relevant ‘time-
    frame[]’ is ‘more seman[t]ical than real . . . [s]ince mental retardation is a developmental
    disability that becomes apparent before adulthood.” 
    2007 WL 4376250
    , at *4 (emphasis added)
    (internal quotation marks omitted). Indeed, the court explained, any “reference to appellant’s
    ‘present status’ and ‘present condition of mental retardation’ is actually a misnomer . . .
    [because] manifestation of mental retardation must occur before age eighteen.” 
    Id.
     The court
    then affirmed the trial court’s decision to unseal the appellant’s prison mental-health records
    because the trial court “d[id] not restrict its review solely to a consideration of appellant’s
    present mental state.” 
    Id.
     (emphasis added); see also id. at *6 (“In the interest of fairness to both
    the State and the offender, an examination of the offender’s past and present mental status would
    serve the interest of justice.”) (internal quotation marks omitted).
    So, far from supporting the Ohio Court of Appeals’s opinion, these cases further establish
    that the court’s wholesale exclusion of past evidence of intellectual disability from its Atkins
    analysis was contrary to clearly established Federal law. See Van Tran, 764 F.3d at 617; Black,
    664 F.3d at 96‒97.
    Nos. 03-3626/12-4269                         Williams v. Mitchell                           Page 17
    Second, the Ohio Court of Appeals’s ruling is contrary to the established definition of
    intellectual disability as set forth in clearly established Supreme Court precedent. As expressed
    in Atkins, “clinical definitions of mental retardation require not only subaverage intellectual
    functioning, but also significant limitations in adaptive skills such as communication, self-care,
    and self-direction that became manifest before age 18.” 
    536 U.S. at 318
    . More precisely, the
    AAMR definition in Atkins made clear: “Mental Retardation manifests before 18.” 
    Id.
     at 308
    n.3. Importantly, the clinical definitions cited with approval by Atkins and adopted by Lott do
    not treat present functioning and early onset as unrelated parts of a disconnected three-part test.
    To the contrary, a plain reading of these clinical definitions makes clear that if an individual is
    indeed presently intellectually disabled, as the term is understood, the disability would have
    manifested itself before the individual turned eighteen. Thus, pursuant to the clinical definitions
    in Atkins, past evidence of intellectual disability—including evidence of intellectual disability
    from an individual’s childhood—is relevant to an analysis of an individual’s present intellectual
    functioning. See Hall v. Florida, 
    134 S. Ct. 1986
    , 1999 (2014) (rejecting Florida’s Atkins test
    where it “[ran] counter to the clinical definition cited throughout Atkins”).
    This is consistent with the Supreme Court’s holding in Heller v. Doe by Doe, 
    509 U.S. 312
     (1993). In Heller, the Court examined the constitutionality of a statute governing the
    involuntary civil commitment of the mentally retarded. Relying on clinical definitions of mental
    retardation from the AAMR and others, the Court held that committing the mentally retarded
    based on clear and convincing evidence of future dangerousness was constitutional because these
    definitions indicated that intellectual disability “becomes apparent before adulthood” and “is a
    permanent, relatively static condition, so a determination of dangerousness may be made with
    some accuracy based on previous behavior.” 
    Id.
     at 321‒23 (emphasis added) (citations omitted).
    This was particularly true for adults because “[b]y the time the person reaches 18 years of age
    the documentation and other evidence of the condition have been accumulated for years.” 
    Id. at 322
    . Thus, “almost by definition in the case of the retarded [adult] there is an 18-year record
    upon which to rely” when assessing the individual’s future intellectual functioning. 
    Id. at 323
    .4
    4
    Indeed, based on the clinical definitions adopted by Heller, courts have overwhelmingly held that
    intellectual capabilities remain stable throughout life and, consequently, evidence of intellectual disability from
    earlier in life is directly relevant to present-day intellectual disability determinations. See Talavera v. Astrue,
    Nos. 03-3626/12-4269                           Williams v. Mitchell                             Page 18
    The Supreme Court’s recent decision in Hall v. Florida also applied medical and clinical
    definitions of intellectual disability—definitions inconsistent with the Ohio Court of Appeals’s
    decision here—in holding Florida’s post-Atkins test unconstitutional.                          The Court in Hall
    addressed “how intellectual disability must be defined” in order to implement Atkins. 134 S. Ct.
    at 1993; see Van Tran, 764 F.3d at 612 (“[Hall] clarified the minimum Atkins standard under the
    U.S. Constitution”).         As in Atkins and Heller, the Court in Hall recognized that, “[i]n
    determining who qualifies as intellectually disabled, it is proper to consult the medical
    community’s opinions.” Hall, 
    134 S. Ct. 1993
    ; see Van Tran, 764 F.3d at 612 (“In Hall, the
    Court reasoned that the Constitution requires the courts and legislatures to follow clinical
    practices in defining intellectual disability.”). Based on these clinical definitions, the Court in
    Hall held that the Florida post-Atkins test was unconstitutional because it failed to take into
    account an IQ test’s five-point Standard Error of Measurement (“SEM”) and it set a strict IQ
    cutoff of 70, both of which were contrary to “unanimous professional consensus” and “counter to
    the clinical definition cited throughout Atkins.” 134 S. Ct. at 1999‒2000. The Court also
    recognized that, “[f]or professionals to diagnose—and for the law then to determine—whether an
    intellectual disability exists,” courts must analyze all factors bearing on the individual’s
    functioning, such as “past performance, environment, and upbringing.” Id. at 1996. Indeed, the
    Court rejected Florida’s post-Atkins test because, under certain circumstances, its scheme did not
    permit consideration of “substantial and weighty evidence” the medical community accepts as
    “probative of intellectual disability,” like “medical histories, behavioral records, school tests and
    reports, and testimony regarding past behavior and family circumstances.” Id. at 1994; see id. at

    also Brumfield v. Cain, --- S. Ct. ----, No. 13-1433,

    (“low birth weight,” placement in special education classes at an “early age,” and “commitment
    to mental health facilities at a young age,” among other evidence, “provided substantial grounds
    to question [the petitioner’s] adaptive functioning”).
    The Ohio Court of Appeals here categorically excluded this “substantial and weighty
    evidence” from its analysis. It also ignored the medical community’s determination, as adopted
    by the Supreme Court, that intellectual disability manifests itself before eighteen and remains
    consistent throughout a person’s life. Consequently, the Ohio Court of Appeals’s treatment of
    intellectual disability as evolving—such that Williams’s intellectual disability pre-eighteen has
    no bearing on his current intellectual functioning—relies on a fundamental misunderstanding of
    governing law. In fact, consistent with these clinical authorities and governing law, the State
    Attorney General’s Office argued repeatedly at oral argument before us in this case that
    intellectual disability does not change over a person’s life. The State’s point was that Williams’s
    more recent IQ score of 75 is thus determinative. While that may ultimately be the case when
    the evidence is weighed (an issue we do not decide here), the State’s position ignores the fact
    that, because intellectual functioning does not generally change throughout a person’s life, past
    evidence of intellectual disability (as the Ohio Court of Appeals found in this case) is also
    relevant to an analysis of present functioning.
    This is particularly important because “[i]ntellectual disability is a condition, not a
    number. Courts must recognize, as does the medical community, that the IQ test is imprecise.”
    Hall, 134 S. Ct. at 2001 (citation omitted). Because of this, courts must consider all evidence
    bearing on an individual’s intellectual functioning in determining whether an intellectual
    disability exists—both past and present. Indeed, the Ohio Court of Appeals’s exclusion of this
    evidence was especially troubling here because the only post-1989 evidence of Williams’s
    intellectual functioning—the preliminary IQ score of 75 from Dr. Eisenberg—placed Williams,
    at worst, on the borderline of being intellectually disabled. See Atkins, 
    536 U.S. at
    309 n.5
    (“[A]n IQ between 70 and 75 or lower . . . is typically considered the cutoff IQ score for the

    Notably, the Court’s analysis regarding the relevance of past evidence of intellectual disability was
    relevant only to the first two Atkins factors because the “age of onset” factor was “not at issue” in Hall. Id. at 1994.
    Nos. 03-3626/12-4269                          Williams v. Mitchell                            Page 20
    intellectual function prong of the mental retardation definition.”); Hall, 
    134 S. Ct. at 1995, 2001
    (“[A]n individual’s [IQ] score is best understood as a range of scores on either side of the
    recorded score,” and courts must consider the five-point SEM margin of error.); Brumfield, --- S.
    Ct. at ----, 
    2015 WL 2473376
    , at *7 (“Accounting for this margin of error, [the petitioner’s]
    reported IQ test result of 75 was squarely in the range of potential intellectual disability.”). Of
    course, how the fact-finder eventually weighs the evidence is beside the point. But weight of the
    evidence was not the issue here—the Ohio Court of Appeals credited this pre-1989 evidence for
    purposes of the early-onset factor, but then improperly found the evidence not “competent” as a
    matter of law for determining present intellectual functioning.6                       The court should have
    recognized instead that the same evidence indicating that Williams was intellectually disabled in
    childhood is directly relevant to whether Williams is intellectually disabled today under the first
    two Lott factors.
    Based on the above authorities, the Ohio Court of Appeals’s holding that pre-1989
    manifestations of intellectual disability have no bearing on an individual’s “present functioning”
    is “substantially different from the relevant precedent of th[e] Court” and “applies a rule that
    contradicts the governing law set forth in [Supreme Court] cases.” Williams, 
    529 U.S. at 405
    .
    As a result, the court’s categorical exclusion of the relevant evidence was contrary to clearly
    established Federal law.
    Finally, the Ohio Court of Appeals’s decision was contrary to clearly established Federal
    law because it applied an arbitrary and disproportionate evidentiary rule to exclude the pre-1989
    evidence at issue. The Supreme Court has clearly established that evidentiary rulings abridge a
    defendant’s due-process right to present evidence when a state court’s exclusion of evidence is
    “arbitrary or disproportionate to the purposes [it is] designed to serve.” United States v. Scheffer,
    
    523 U.S. 303
    , 308 (1998) (internal quotation marks omitted); Holmes v. S. Carolina, 
    547 U.S. 319
    , 326 (2006) (“[T]he Constitution . . . prohibits the exclusion of defense evidence under rules
    that serve no legitimate purpose or that are disproportionate to the ends that they are asserted to
    6
    The State suggested at oral argument before us that the Ohio Court of Appeals did not categorically
    exclude the evidence, but instead, the court rejected the evidence because it was not properly presented. But
    nowhere did the court suggest that the evidence was improperly presented; again, to the contrary, it credited the pre-
    1989 evidence in finding that Williams satisfied the third Lott factor. The court clearly excluded the evidence from
    “prior to 1989” because the court held this evidence “d[id] not constitute competent evidence from which inferences
    may be made regarding [Williams’s] present mental capacity.” Williams, 
    2008 WL 2582849
    , at *6.
    Nos. 03-3626/12-4269                            Williams v. Mitchell                             Page 21
    promote.”). The Court has defined “arbitrary” evidentiary rules as rules that exclude important
    evidence “but that d[o] not serve any legitimate interests.” Holmes, 
    547 U.S. at 325
    . “[T]he
    exclusion of evidence [is] unconstitutionally arbitrary or disproportionate only where it has
    infringed upon a weighty interest of the accused.” Scheffer, 
    523 U.S. at 308
    ; Holmes, 
    547 U.S. at
    324‒25; see also Loza v. Mitchell, 
    766 F.3d 466
    , 485 (6th Cir. 2014) (“The ‘clearly
    established Federal law,’ § 2254(d)(1), at issue is that a defendant’s right to present a complete
    defense is violated when a state court excludes important evidence on the basis of an arbitrary,
    mechanistic, or per se rule, or one that is disproportionate to the purposes it is designed to
    serve.”) (internal quotation marks omitted).7
    Here, the Ohio Court of Appeals’s decision to exclude categorically pre-1989 evidence of
    Williams’s intellectual disability was arbitrary and disproportionate.                         The Ohio Court of
    Appeals’s “mechanistic, per se rule” rejected evidence from “prior to 1989” offered by Williams
    as not “competent evidence” of “present mental capacity” under the first two Lott factors. But
    the court appears to have credited Williams’s prison records—which span fifteen years—along
    with evidence of the underlying crimes—which occurred in 1988—as “considerable evidence”
    of Williams’s “current” limitations in adaptive skills. How the latter evidence (i.e., prison
    records, the underlying crimes) was “current” when the trial court analyzed the evidence in 2004
    and the Ohio Court of Appeals affirmed in 2008 is unclear. Moreover, the court failed to explain
    why 1989 was the magical line between past and present functioning. Williams was a twenty-
    one-year-old adult in 1989, so the court’s distinction was not between juvenile and adult records
    (though, for the reasons noted above, categorically excluding the evidence for this reason would
    have been improper, too). Instead, the court’s pre-1989 cutoff appears unmoored to reason or
    principle—despite purporting to exclude all “past” evidence from its analysis of the first two Lott
    factors, essentially, the court applied its categorical exclusion only to evidence submitted by
    Williams.      The court’s per se exclusionary rule was thus unconstitutionally arbitrary and
    7
    Although these principles are generally applied to a criminal defendant’s ability to present a defense
    during a criminal trial, they apply with equal force in the Atkins context. In Atkins, the Court held that intellectual
    disabilities diminish an individual’s “personal culpability” and, as a result, people with intellectual disability must be
    “categorically excluded from execution.” Atkins, 
    536 U.S. at 319
    . It would be anomalous to hold that these due-
    process principles of fundamental fairness do not apply to evidentiary determinations in proceedings to determine
    whether the death penalty should be imposed. See Hall, 
    134 S. Ct. at 2001
     (“The death penalty is the gravest
    sentence our society may impose. Persons facing that most severe sanction must have a fair opportunity to show
    that the Constitution prohibits their execution.”).
    Nos. 03-3626/12-4269                   Williams v. Mitchell                    Page 22
    disproportionate. And, of course, the decision infringed upon a weighty interest: the court’s
    decision to exclude this important evidence indicating that Williams was intellectually disabled
    before age eighteen (a finding that the parties agree would normally hold static throughout
    Williams’s lifetime) was directly relevant to the obviously extremely important issue of whether
    Williams should live or die based on his intellectual functioning. Thus, for this reason too, the
    court’s blanket exclusion of the evidence was contrary to clearly established Federal law.
    C. Remand
    Finally, Williams argues that because the state court wrongly found that he failed to
    demonstrate a prima facie case of intellectual disability, the federal district court should have
    granted Williams discovery and held an evidentiary hearing. But we need not reach that issue
    here. The Ohio Court of Appeals’s decision was contrary to clearly established Federal law
    under § 2254(d) for improperly excluding evidence relevant to Williams’s Atkins claim. As set
    forth above, the Ohio Court of Appeals rejected relevant facts that were necessary to rule on
    Williams’s Atkins claim; and it did so based on a misreading of United States Supreme Court
    jurisprudence and the Ohio Supreme Court’s implementing decisions in Lott and White. Because
    of this error, the operative state-court decision did not definitively resolve the merits of
    Williams’s Atkins claim under a correct reading of the facts and law. We thus do not reach the
    merits of Williams’s Atkins claim. See Black, 664 F.3d at 101 (“[W]e will refrain from reaching
    any independent conclusions ourselves because no court has yet analyzed Black’s Atkins claim
    according to the proper legal standard.”).
    Instead, the proper course is to grant a writ of habeas corpus prohibiting imposition of the
    death penalty, conditioned upon a fresh analysis by the Ohio courts as to whether Williams is
    intellectually disabled pursuant to governing law. Indeed, this is the course we took in Van Tran,
    where the state court decision “did not apply the proper legal standard and was therefore contrary
    to clearly established governing law” because it improperly disregarded relevant evidence in its
    analysis. Van Tran, 764 F.3d at 619‒20 (“When a constitutional error may be cured by further
    state proceedings, the common course is to grant the writ of habeas corpus conditional upon the
    state court’s correcting the error.”); see Gentry v. Deuth, 
    456 F.3d 687
    , 692 (6th Cir. 2006)
    Nos. 03-3626/12-4269                        Williams v. Mitchell                          Page 23
    (“[C]onditional grants [of habeas writs] . . . provide states with an opportunity to cure their
    constitutional errors, out of a proper concern for comity among the co-equal sovereigns.”).
    In remanding, we note that clearly established Federal law, as set forth above, requires
    courts to consider all relevant evidence bearing on an individual’s intellectual functioning and to
    apply clinical principles of intellectual disability adopted by federal precedent. See, e.g., Hall,
    
    134 S. Ct. at 2001
     (remanding so petitioner could present evidence of his intellectual deficits
    “over his lifetime”); Heller, 
    509 U.S. at 323
     (recognizing that an intellectual disability “is a
    permanent, relatively static condition”). Indeed, the most recent evidence in the record is well
    over ten years old, so this could include presentation of new evidence from both Williams and
    the State relevant to Williams’s functioning. See Hall, 
    134 S. Ct. at 2001
     (“Intellectual disability
    is a condition, not a number. Courts must recognize, as does the medical community, that the IQ
    test is imprecise.”) (citation omitted).          But whether to grant an evidentiary hearing after
    considering all relevant evidence and applying the applicable law is for the state court to decide
    in the first instance. See OHIO REV. CODE § 2953.21(E) (“Unless the petition and the files and
    records of the case show the petitioner is not entitled to relief, the court shall proceed to a prompt
    hearing on the issues.”); see also Brumfield, --- S. Ct. at ----, 
    2015 WL 2473376
    , at *10 (holding
    state court erred by failing to hold evidentiary hearing before adjudicating Atkins petition based,
    in part, on evidence of intellectual disability from the petitioner’s childhood).
    IV. CONCLUSION
    For the foregoing reasons, Williams is not entitled to relief on his claim of ineffective
    assistance of counsel. But the Ohio state court’s application of law with regard to whether
    Williams is intellectually disabled under Atkins was contrary to clearly established Federal law.
    Accordingly, we VACATE and REMAND so that the district court may grant a
    CONDITIONAL WRIT OF HABEAS CORPUS prohibiting Williams’s execution unless the
    State reassesses Williams’s Atkins petition consistent with this opinion.8

    We leave it to the district court to impose any necessary procedures and time limits for conducting this
    reassessment.

    CONCURRING IN PART AND IN THE JUDGMENT
    ___________________________________________________
    JULIA SMITH GIBBONS, Circuit Judge, concurring.                               I agree that our precedents
    compel reversal for the reasons explained in the majority opinion and concur in all of it except
    the two paragraphs concluding that the Ohio Court of Appeals decision was contrary to clearly
    established Federal law because it applied an arbitrary and disproportionate evidentiary ruling to
    exclude the pre-1989 evidence at issue. I elaborate slightly on the analysis that provides for me
    the most obvious and straightforward basis for resolution of this appeal.1
    AEDPA’s limited grounds for relief include a state court’s decision on the merits that
    unreasonably applied clearly established Federal law. 
    28 U.S.C. § 2254
    (d). A state court
    unreasonably applies the law if “there is no possibility fairminded jurists could disagree that the
    state court’s decision conflicts with [the Supreme] Court’s precedents.” Harrington v. Richter,
    
    131 S. Ct. 770
    , 786 (2011).
    Here, no fairminded jurist could disagree that the Ohio Court of Appeals violated the
    clearly established law set out in Atkins v. Virginia, 
    536 U.S. 304
     (2002), and Hall v. Florida,
    
    134 S. Ct. 1986
     (2014). Under this theory—unlike the theory upon which the majority opinion
    principally relies—we need not decide whether the state faithfully applied its own precedent,
    State v. Lott, 
    779 N.E.2d 1011
     (Ohio 2002), in this instance. Instead, we proceed to the heart of
    the issue and ask simply whether the state court decision involved an unreasonable application of
    the clearly established law that the Supreme Court announced in Atkins and Hall.
    The clearly established mandate of those cases, for present purposes, is twofold. First,
    states may take different routes but must reach the same end point: ensuring that no intellectually
    disabled individual is subjected to the state’s death penalty. Atkins, 
    536 U.S. at 317
    ; Hall, 
    134 S. Ct. at 2001
     (“The States are laboratories for experimentation, but those experiments may not
    deny the basic dignity the Constitution protects.”). Second, in deciding which individuals are
    intellectually disabled, states do not operate in a vacuum. Their tests must be tethered to the
    1
    Discussion of this issue is found at pp. 17–20 of the majority opinion.
    Nos. 03-3626/12-4269                   Williams v. Mitchell                     Page 25
    definition of intellectual disability that the Supreme Court has recognized, a definition that is
    itself heavily influenced by the medical understanding of that condition. Hall, 
    134 S. Ct. at 2000
    (“The legal determination of intellectual disability is distinct from a medical diagnosis, but it is
    informed by the medical community’s diagnostic framework.              Atkins itself points to the
    diagnostic criteria employed by psychiatric professionals.”); Kansas v. Crane, 
    534 U.S. 407
    , 413
    (2002) (“[T]he science of psychiatry . . . informs but does not control ultimate legal
    determinations . . . .”).
    The Court applied this standard in Hall in holding that Florida’s scheme for assessing
    intellectual disability was incompatible with Atkins. Florida courts imposed a rigid rule requiring
    a defendant to demonstrate an IQ of seventy or below as a threshold matter. Id. at 1992.
    Without such a showing, a defendant would be unable to prove intellectual disability, no matter
    the other circumstances. See id. Of the two IQ tests that were admissible in Hall’s trial, neither
    showed an IQ of seventy or below. Id. The Florida Supreme Court therefore concluded that he
    was unable to demonstrate intellectual disability, and that the Eighth and Fourteenth
    Amendments did not bar his execution.          Id.   Drawing on the medical understanding of
    intellectual disability set forth in Atkins, the U.S. Supreme Court reversed. Id. at 2001. It
    emphasized that IQ test scores are mere “approximations of conceptual functioning,” subject to a
    standard error of measurement. Id. at 2000 (internal quotation marks omitted). As a result, “an
    individual with an IQ test score ‘between 70 and 75 or lower’ . . . may show intellectual
    disability by presenting additional evidence regarding difficulties in adaptive functioning.” Id. at
    2000 (quoting Atkins, 
    536 U.S. at
    309 n.5). Florida’s test “contradict[ed] the [IQ] test’s own
    design,” by failing to account for the standard error of measurement and eliminating “an
    essential part of a sentencing court’s inquiry into adaptive functioning.” Id. at 2001. The state
    law therefore contradicted “the unanimous professional consensus.”           Id. at 2000 (internal
    quotation marks omitted).
    No fairminded jurist could disagree that the Ohio Court of Appeals went similarly awry
    in Williams. The U.S. Supreme Court, adopting the consensus of the medical community,
    understands intellectual disability as a permanent condition, affecting a defendant not only at the
    time of the offense, but also at the times of trial and execution. Atkins, 
    536 U.S. at
    319–21; see
    Nos. 03-3626/12-4269                         Williams v. Mitchell                          Page 26
    also Heller v. Doe, 
    509 U.S. 312
    , 323 (1993) (noting, in a different context, that intellectual
    disability “is a permanent, relatively static condition” (citing S. Brakel et al., The Mentally
    Disabled and the Law 37 (3d ed. 1985))). This is why intellectual disability makes an individual
    permanently ineligible for execution, unlike an individual deemed incompetent for execution,
    who may later regain competency and be executed. See, e.g., Singleton v. Norris, 
    319 F.3d 1018
    ,
    1027 (8th Cir. 2003) (en banc) (citing Ford v. Wainwright, 
    477 U.S. 399
     (1986)). The Atkins
    Court further noted that intellectual disability “‘may be seen as a final common pathway of
    various pathological processes that affect the functioning of the central nervous system,’” Atkins,
    
    536 U.S. at
    308 n.3 (quoting Diagnostic and Statistical Manual of Mental Disorders 41 (4th ed.
    2000)), and discussed the deficiencies in cognitive and adaptive functioning that characterize an
    intellectually disabled person, 
    id.
     at 308 n.4, 309 n.5.2 It is clear from the entire thrust of the
    Atkins decision—along with the medical literature that it cites in support—that intellectual
    disability is a permanent condition.
    The Ohio Court of Appeals—by contrast—approached the evidence of Williams’s
    alleged intellectual disability as if it were a transient condition. That court held that pre-1989
    evidence of Williams’s subaverage intellectual functioning and deficits in adaptive functioning
    “only attest his intellectual functioning prior to 1989” and therefore “do not constitute competent
    evidence from which inferences may be made regarding his present mental capacity.” State v.
    Williams, No. 2007-T-0105, 
    2008 WL 2582849
    , at *6 (Ohio Ct. App. June 27, 2008).3 Given the
    enduring nature of intellectual disability, there is no basis for excluding evidence from earlier in
    Williams’s life.      If Williams was intellectually disabled in 1989, he remains intellectually
    disabled now. By excluding the pre-1989 evidence, the state court severely limited its own
    ability to make a reasoned assessment of Williams’s condition according to the legal and medical
    standard that Atkins and Hall plainly require. Andre Williams “may or may not be intellectually
    disabled, but the law requires that he have the opportunity to present evidence of his intellectual
    disability.” See Hall, 
    134 S. Ct. at 2001
    . That includes the evidence that the state court excluded
    here.
    2
    The Atkins decision and the material it cites refer to the condition as “mental retardation.” In modern
    lexicon, the preferred term is “intellectual disability.” See Hall, 
    134 S. Ct. at 1990
    .
    3
    Williams turned 22 in 1989. See Williams, 
    2008 WL 2582849
    , at *2.
    Nos. 03-3626/12-4269                    Williams v. Mitchell                     Page 27
    Regardless of whether the Ohio Court of Appeals followed its own state’s law, no
    fairminded jurist could disagree that its decision conflicts with the clearly established law
    enunciated in Atkins and Hall. This provides an alternative basis for relief under AEDPA.
    I also touch briefly on my quibble with the portion of the majority opinion in which I do
    not concur. This third rationale is not necessary and I question whether it is appropriate here.
    The Ohio Court of Appeals did not explicitly invoke any evidentiary rule when it excluded the
    pre-1989 evidence. The court stated that that evidence was not “competent” to prove present
    intellectual deficits. In the context of the opinion, this appears to mean that the pre-1999
    evidence is not relevant to the Atkins/Lott test (other than the “onset before 18” prong).
    This evidentiary ruling was not arbitrary or disproportionate. The state court excluded
    the evidence simply because it misunderstood and misapplied Atkins and Lott. If it had been
    correct that intellectual disability can fluctuate and that present functioning was a separate fact to
    be proven, it would have been correct to exclude the pre-1989 evidence as irrelevant. In reality,
    the court’s erroneous exclusion of the evidence was due to a misapplication of the substantive
    law (an issue the opinion already analyzes), not an arbitrary or disproportionate evidentiary
    ruling.
