    SUMMARY*
    Habeas Corpus/Death Penalty
    The panel affirmed the district court’s denial of a
    
    28 U.S.C. § 2254
     habeas corpus petition challenging a murder
    conviction and capital sentence.
    The panel held that the use of dual juries, one for
    petitioner and one for his co-defendant, did not violate clearly
    established federal law, despite petitioner’s claim that this
    method led to a prejudicial courtroom layout where petitioner
    sat facing the jurors throughout trial. The panel held that
    petitioner procedurally defaulted on his other dual juries
    challenges.
    The panel held that petitioner procedurally defaulted on
    his claim that the trial court violated his rights by requiring
    him to wear a leg brace during trial.
    The panel rejected petitioner’s claim, under Lockett v.
    Ohio, 
    438 U.S. 586
     (1987), and Eddings v. Oklahoma,
    
    455 U.S. 104
     (1982), that the trial court did not adequately
    consider mitigating factors in imposing the death penalty,
    explaining that these cases only hold that a sentencer must
    fully consider proffered mitigating evidence, and do not
    affect a sentencer’s determination of the weight of the
    evidence.

    Judge Wardlaw concurred in part and dissented in part.
    She agreed with the majority’s conclusion that the denial of
    relief as to petitioner’s dual juries and shackling claims must
    be upheld for failure to exhaust them. However, she
    disagreed with the majority’s analysis of the Eddings claim,
    and would reverse the district court’s denial of relief and
    instruct that court to grant the petition as to that claim.

    OPINION
    N.R. SMITH, Circuit Judge:
    Petitioner James Erin McKinney, an Arizona state
    prisoner, appeals the district court’s denial of his 
    28 U.S.C. § 2254
     habeas corpus petition. The Arizona state court
    sentenced McKinney to death on each of two counts of first-
    degree murder for the 1991 killings of Christene Mertens and
    Jim McClain. We affirm the district court.
    In this opinion we address three claims raised in
    McKinney’s petition: (1) the trial court’s use of dual juries at
    trial; (2) the trial court’s use of a leg brace as a security
    4                      MCKINNEY V. RYAN
    measure during trial; and (3) whether the sentencing judge
    properly considered all mitigating evidence under Lockett v.
    Ohio, 
    438 U.S. 586
     (1978), and Eddings v. Oklahoma,
    
    455 U.S. 104
     (1982).1 McKinney failed to exhaust each of
    these claims except one of his several dual juries claims and
    the Lockett/Eddings claim. McKinney’s unexhausted claims
    are procedurally defaulted, because he would now be barred
    from raising them to the Arizona state courts. See Beaty v.
    Stewart, 
    303 F.3d 975
    , 987 (9th Cir. 2002) (citing Ariz. R.
    Crim. P. 32.2(a)). As to the remaining claims, the Arizona
    Supreme Court’s decision to deny relief was not contrary to,
    nor an unreasonable application of, clearly established federal
    law or based on an unreasonable determination of the facts
    before that court. See 
    28 U.S.C. § 2254
    (d).
    FACTS AND PROCEDURAL HISTORY
    A. Background2
    On February 28, 1991, McKinney and his half brother,
    co-defendant Michael Hedlund, committed the first in a string
    of five residential burglaries. Before this first burglary,
    1
    McKinney raises other uncertified claims on appeal. Because
    McKinney has not shown that the district court’s resolution of the other
    claims is “debatable amongst jurists of reason,” Miller-El v. Cockrell,
    
    537 U.S. 322
    , 336 (2003), we decline to expand the certificate of
    appealability to review the claims. See 
    28 U.S.C. § 2253
    (c); Hiivala v.
    Wood, 
    195 F.3d 1098
    , 1102–04 (9th Cir. 1999) (per curiam).
    2
    These facts are drawn substantially from the Arizona Supreme Court’s
    opinion in State v. McKinney, 
    917 P.2d 1214
    , 1218–19 (Ariz. 1996) (en
    banc), superseded by statute on other grounds as stated in State v.
    Martinez, 
    999 P.2d 795
    , 806 (Ariz. 2000) (en banc). We presume the
    correctness of the Arizona court’s findings unless rebutted by clear and
    convincing evidence. See 
    28 U.S.C. § 2254
    (e)(1).
    MCKINNEY V. RYAN                       5
    McKinney and Hedlund (collectively, “Defendants”) were
    driving in Hedlund’s car with Chris Morris and Joe Lemon,
    discussing potential targets. Brandishing his gun, McKinney
    stated that he would shoot anyone that they found at home
    during the burglaries. Hedlund said that he would beat
    anyone that he encountered in the head.
    At the time, Defendants had learned from Morris and
    Lemon that Christene Mertens supposedly kept thousands of
    dollars in an orange juice container in her refrigerator.
    Therefore, Defendants and Morris and Lemon intended to
    burglarize Mertens’s home on the first night of the burglary
    spree. However, Mertens came home and scared the would-
    be burglars away. As a result, the four of them chose a
    different house to burglarize, but obtained nothing of value
    from the burglary.
    The next night, McKinney, Hedlund, and Morris
    committed two more burglaries. Lemon was not involved.
    McKinney and Morris stole a .22 revolver, twelve dollars,
    some wheat pennies, a tool apron, and a Rolex
    watch—splitting the “proceeds” with Hedlund after the
    crimes. When the homeowner returned home during the third
    burglary, McKinney and Morris ran away, leaving the
    homeowner unharmed. However, after the burglary,
    McKinney remarked that he and Morris “should have stayed
    and [McKinney] would have shot [the homeowner].”
    On March 9, 1991, McKinney and Hedlund returned to
    the Mertens home for the fourth burglary. When they entered
    the residence, Defendants found Mertens home alone and
    attacked her. After the attack Mertens had both gunshot and
    stab wounds. However, the medical examiner certified the
    cause of death as “a penetrating contact gunshot wound to the
    6                   MCKINNEY V. RYAN
    head.” Defendants ransacked the house and stole $120 in
    cash.
    Defendants committed the fifth burglary and second
    murder at the home of Jim McClain on March 22, 1991.
    Defendants knew McClain, because Hedlund had bought a
    car from him about six months before the murder. McClain’s
    house was ransacked during the course of the burglary, and
    he was shot in the back of the head while sleeping.
    Defendants stole a pocket watch, three handguns, and
    McClain’s car. Defendants later tried to sell the stolen guns.
    McKinney was tried on two counts of first degree murder,
    two counts of burglary, one count of theft, and one count of
    attempted theft. The trial court tried Defendants together, but
    empaneled separate juries to decide the guilt of each
    Defendant. The trial court required both Defendants to wear
    a leg brace as a security measure throughout the trial.
    McKinney’s jury found him guilty of all charges, except the
    attempted theft charge. The trial judge sentenced McKinney
    to death on each first degree murder conviction. State v.
    McKinney, 
    917 P.2d 1214
    , 1218 (Ariz. 1996) (en banc),
    superseded by statute on other grounds as stated in State v.
    Martinez, 
    999 P.2d 795
    , 806 (Ariz. 2000) (en banc).
    B. Post-conviction proceedings
    The Arizona Supreme Court upheld McKinney’s
    convictions and sentence on direct appeal. McKinney,
    
    917 P.2d at 1234
    .
    McKinney thereafter challenged his convictions and
    sentence in post-conviction collateral proceedings. The
    Maricopa County superior court (the “State PCR Court”)
    MCKINNEY V. RYAN                          7
    concluded that none of the claims raised in McKinney’s
    operative petition for post-conviction relief (the “PCR
    Petition”) presented material issues of fact or law to warrant
    further proceedings. The State PCR Court summarily
    dismissed the petition. McKinney appealed the dismissal of
    the PCR Petition to the Arizona Supreme Court, which denied
    review on all claims relevant to this appeal.
    Thereafter, McKinney raised 26 claims in his petition for
    writ of habeas corpus to the U.S. District Court for the
    District of Arizona. The district court denied relief on a
    number of these claims in 2006 and on the remaining claims
    in 2009. In its order denying relief, the district court granted
    a certificate of appealability (“COA”) on the issues of
    whether the trial court’s use of dual juries or a leg brace
    violated McKinney’s rights. The district court denied a COA
    on the remaining issues.
    STANDARD OF REVIEW
    “We review de novo the district court’s decision to grant
    or deny a petition for a writ of habeas corpus.” Rhoades v.
    Henry, 
    598 F.3d 495
    , 500 (9th Cir. 2010).
    The Antiterrorism and Effective Death Penalty Act of
    1996 (“AEDPA”) governs this case. See Lindh v. Murphy,
    
    521 U.S. 320
    , 336–37 (1997); Lopez v. Schriro, 
    491 F.3d 1029
    , 1036–38 (9th Cir. 2007). A petitioner must overcome
    a high threshold to obtain relief under AEDPA:
    Federal habeas relief may not be granted for
    claims subject to § 2254(d) unless it is shown
    that the earlier state court’s decision was
    contrary to federal law then clearly
    8                   MCKINNEY V. RYAN
    established in the holdings of [the Supreme]
    Court, § 2254(d)(1); or that it involved an
    unreasonable application of such law,
    § 2254(d)(1); or that it was based on an
    unreasonable determination of the facts in
    light of the record before the state court,
    § 2254(d)(2).
    Harrington v. Richter, ___ U.S. ___, 
    131 S. Ct. 770
    , 785
    (2011) (internal quotation marks and citation omitted).
    The “only definitive source of clearly established federal
    law under AEDPA is the holdings (as opposed to the dicta) of
    the Supreme Court as of the time of the state court decision.”
    Clark v. Murphy, 
    331 F.3d 1062
    , 1069 (9th Cir. 2003),
    overruled on other grounds by Lockyer v. Andrade, 
    538 U.S. 63
     (2003)). If Supreme Court “cases give no clear answer to
    the question presented, . . . it cannot be said that the state
    court unreasonably applied clearly established Federal law.”
    Wright v. Van Patten, 
    552 U.S. 120
    , 126 (2008) (internal
    quotation marks omitted). In other words, “‘[i]t is not an
    unreasonable application of clearly established Federal law
    for a state court to decline to apply a specific legal rule that
    has not been squarely established by [the Supreme Court].’”
    Richter, 
    131 S. Ct. at 786
     (quoting Knowles v. Mirzayance,
    
    556 U.S. 111
    , 122 (2009)).
    In cases where a petitioner identifies clearly established
    federal law and challenges the state court’s application of that
    law, our task under AEDPA is not to decide whether a state
    court decision applied the law correctly. See id. at 785.
    Rather, we must decide whether the state court decision
    applied the law reasonably. See id. (“‘[A]n unreasonable
    application of federal law is different from an incorrect
    MCKINNEY V. RYAN                                 9
    application of federal law.’” (quoting Williams v. Taylor,
    
    529 U.S. 362
    , 410 (2000)). If the state court applied the law
    reasonably, we must deny relief. See 
    id.
     Thus, we grant
    relief only “in cases where there is no possibility fairminded
    jurists could disagree that the state court’s decision conflicts
    with [the Supreme Court’s] precedents.” Id. at 786.
    DISCUSSION
    I. Dual Juries Claims
    McKinney raises a number of claims based on the trial
    court’s use of dual juries. However, McKinney exhausted3
    only one of them in the state courts, as AEDPA requires—his
    claim that the use of dual juries led to a prejudicial courtroom
    layout where McKinney sat facing the jurors throughout trial.
    McKinney’s “courtroom layout” claim fails, because he has
    failed to identify clearly established federal law that would
    provide the basis for relief under § 2254(d)(1). McKinney
    failed to exhaust any of the other potential dual juries claims
    and would now be barred from raising these claims in state
    court. See Beaty, 
    303 F.3d at
    987 (citing Ariz. R. Crim. P.
    32.2(a)). Accordingly, McKinney’s “other” dual juries
    3
    The exhaustion doctrine requires a petitioner to provide the state courts
    with the opportunity to rule on his federal constitutional claims before
    presenting these claims to a federal habeas court. See King v. Ryan,
    
    564 F.3d 1133
    , 1138 (9th Cir. 2009); 
    28 U.S.C. § 2254
    (b)(1) (proving that
    a writ of habeas corpus shall not be granted unless “the applicant has
    exhausted the remedies available in the courts of the State”).
    10                       MCKINNEY V. RYAN
    claims are procedurally defaulted,4 and he has not shown
    cause or prejudice to excuse the default. See 
    id.
    A. Background and procedural history
    Before trial, Hedlund moved to sever his case from
    McKinney’s, and the State did not oppose the motion. The
    trial court initially granted the motion to sever. The trial
    court later asked the parties for briefing on the idea of using
    dual juries.
    Thereafter, the trial court held a hearing on the use of dual
    juries. The State opposed the practice based on a perceived
    state procedural obstacle set forth in State v. Lambright,
    
    673 P.2d 1
     (Ariz. 1983) (en banc), overruled by Hedlund v.
    Sheldon, 
    840 P.2d 1008
     (Ariz. 1992) (en banc). McKinney
    shared the State’s Lambright concern and argued that it
    would be improper for the court to employ an untested dual
    jury procedure. McKinney also argued that severance was
    required to avoid the introduction of impermissible,
    incriminating testimony under Bruton v. United States,
    
    391 U.S. 123
     (1968).
    The trial court concluded that the use of the dual juries
    would not impede Defendants’ right to fair trial, and found no
    inherent prejudice in the use of dual juries. At trial, both
    4
    A state prisoner procedurally defaults federal claims if he fails to raise
    them as federal claims in state court or if, in raising the claims, he fails to
    comply with applicable state procedural rules. Coleman v. Thompson,
    
    501 U.S. 722
    , 730–31 (1991). The state can successfully assert a
    procedural default defense to federal habeas review unless the prisoner
    can show both “cause” for the procedural default and actual prejudice, or
    the prisoner demonstrates that failure to consider the claims will result in
    a fundamental miscarriage of justice. 
    Id. at 750
    .
    MCKINNEY V. RYAN                          11
    Defendants’ juries were present in the courtroom, except
    during “the reading of charges, opening statements, closing
    arguments, and testimony related to a particular defendant’s
    inculpatory statements.” Both before and during trial, the
    trial court reminded counsel to preserve the integrity of the
    dual jury procedure and to avoid eliciting testimony non-
    admissible against the other codefendant under Bruton.
    Before trial, McKinney challenged the use of dual juries
    in a special action to the Arizona Court of Appeals. See
    Hedlund, 
    840 P.2d at 1009
    . The court of appeals reversed,
    holding that the trial court exceeded its authority under the
    Arizona Rules of Criminal Procedure and the Arizona
    Supreme Court’s decision in Lambright. 
    Id.
     The Arizona
    Supreme Court reversed the court of appeals and affirmed the
    trial court’s decision to use dual juries. 
    Id. at 1011
    .
    On direct appeal of his conviction and sentence,
    McKinney claimed that the dual juries caused the courtroom
    layout “with Defendants facing the jurors, [to be] intimidating
    and resulted in fundamental error requiring reversal.”
    McKinney, 
    917 P.2d at 1232
    . The Arizona Supreme Court
    rejected this argument, concluding that McKinney could not
    demonstrate prejudice and provided no authority for “a
    constitutional right to a standard American courtroom
    arrangement.” 
    Id.
    McKinney raised the “courtroom layout” issue again in
    his PCR Petition. The State PCR Court rejected McKinney’s
    argument that the courtroom layout “tainted” the proceedings.
    McKinney also argued in the PCR Petition that the use of the
    dual juries violated his “right to a fundamentally fair trial” for
    a number of other reasons. However, McKinney did not
    12                  MCKINNEY V. RYAN
    invoke the U.S. Constitution, nor did he cite to any state or
    federal cases.
    McKinney raised the same “courtroom layout” claim in
    his federal habeas petition. McKinney also made a number
    of other arguments that the use of the dual juries prejudiced
    his right to a fair trial. The federal district court addressed
    each sub-part of McKinney’s dual juries claim. Of those, the
    district court concluded that only McKinney’s “courtroom
    layout” claim was even “arguably exhausted in state court.”
    Despite this conclusion, however, the district court rejected
    all of McKinney’s arguments on the merits.
    B. “Courtroom layout” claim
    McKinney exhausted his “courtroom layout” claim. “To
    exhaust his Arizona remedies, [a petitioner must] give the
    Arizona courts a fair opportunity to act on his federal due
    process claim before presenting it to the federal courts.”
    Castillo v. McFadden, 
    399 F.3d 993
    , 998 (9th Cir. 2005)
    (internal quotation marks omitted). In so doing, a petitioner
    must apprise the state court that he is “making a claim under
    the U.S. Constitution, and describe both the operative facts
    and the federal legal theory on which [the] claim is
    based . . . .” 
    Id. at 999
     (internal quotation marks and citation
    omitted). This can be accomplished by citing “specific
    provisions of the federal constitution or . . . federal or state
    cases involving the legal standard for a federal constitutional
    violation.”      
    Id.
         “Mere ‘general appeals to broad
    constitutional principles, such as due process, equal
    protection, and the right to a fair trial,’ do not establish
    exhaustion.” 
    Id.
     (quoting Hiivala v. Wood, 
    195 F.3d 1098
    ,
    1106 (9th Cir. 1999) (per curiam)); see also Fields v.
    Waddington, 
    401 F.3d 1018
    , 1021 (9th Cir. 2005) (holding
    MCKINNEY V. RYAN                        13
    that a petitioner failed to exhaust a federal due process claim
    where petitioner’s briefing to the state court mentioned the
    federal constitution only twice and due process only once).
    In short, a petitioner must “alert the state courts to the fact
    that he [is] asserting a claim under the United States
    Constitution.” Hiivala, 
    195 F.3d at 1106
    .
    McKinney set forth the “federal legal theory” underlying
    his prejudicial courtroom layout claim in his opening brief to
    the Arizona Supreme Court. McKinney claimed: “The
    bizarre and prejudicial seating arrangement deprived the
    appellant of due process under the Arizona and Federal
    Constitutions.” The brief’s table of contents also cites the
    page containing that sentence under its entry for the “Fifth
    Amendment.” Taken together, the argument and the table of
    contents allude to a specific provision of the U.S.
    Constitution. McKinney’s brief also invokes the U.S.
    Constitution numerous times in reference to other claims.
    Accordingly, McKinney’s brief was sufficient to alert the
    Arizona Supreme Court that McKinney raised a federal
    claim. See Robinson v. Schriro, 
    595 F.3d 1086
    , 1103 (9th
    Cir. 2010) (“This is not a case where the petitioner failed to
    make clear that he was invoking a federal right, or where the
    petitioner’s general appeal to a constitutional guarantee was
    too vague to put the state court on notice of the federal
    claim.” (internal citations and quotation marks omitted));
    Hiivala, 
    195 F.3d at 1106
    . Thus, we conclude that McKinney
    exhausted his “courtroom layout” claim.
    Turning to the merits of McKinney’s “courtroom layout”
    claim, we must determine whether the Arizona Supreme
    Court’s decision rejecting this claim was contrary to, or an
    unreasonable application of, clearly established federal law.
    We conclude that it was not. McKinney cites no Supreme
    14                   MCKINNEY V. RYAN
    Court case, and our search reveals no case, that would
    provide the basis for relief under § 2254(d)(1). Accordingly,
    we echo the Arizona Supreme Court’s McKinney opinion,
    which held: “McKinney has not demonstrated any prejudice
    and provides no authority for his argument that there is a
    constitutional right to a standard American courtroom
    arrangement, and we decline to invent such a right.”
    
    917 P.2d at 1232
    . McKinney is not entitled to relief on his
    prejudicial courtroom layout claim.
    C. McKinney’s “other” dual juries claims
    In addition to the “courtroom layout” claim, McKinney
    makes several arguments in federal court that the use of the
    dual juries denied him his right to a fair trial. McKinney
    claims the dual juries prejudiced him, because: (1)
    Defendants presented antagonistic defenses, which led to
    prejudicial leading questions, limited cross-examination, and
    Bruton violations; and (2) the procedure necessitated
    increased security and the use of a leg brace during trial. The
    State argues that McKinney procedurally defaulted these
    claims by failing to fairly present them to the state court. We
    agree.
    1. McKinney failed to exhaust his “other” courtroom
    layout claims.
    McKinney’s Arizona Supreme Court briefing did not set
    forth the operative facts or federal legal theory for any dual
    juries claim apart from the “courtroom layout” claim. The
    same is true of the PCR Petition. While the PCR Petition
    makes a general appeal to McKinney’s right to “due process”
    and a “fair trial,” this is insufficient to exhaust. See Castillo,
    
    399 F.3d at 998
    ; Hiivala, 
    195 F.3d at 1106
    . Accordingly,
    MCKINNEY V. RYAN                               15
    McKinney failed to exhaust any potential claim arising out of
    the trial court’s use of dual juries, except the “courtroom
    layout” claim.
    McKinney argues that his claims were exhausted, because
    Hedlund raised the claims to the Arizona Supreme Court.
    However, “[t]he questions raised by [McKinney] involve
    constitutional privileges which are personal to him, and
    therefore an appeal by his co-defendant can not exhaust [his]
    remedies in the state courts.” Williams v. Nelson, 
    431 F.2d 932
    , 932–33 (9th Cir. 1970) (per curiam).5 Accordingly,
    McKinney failed to exhaust these claims because he failed to
    raise them personally to the state court.
    2. McKinney’s unexhausted dual juries claims are
    procedurally defaulted.
    “A claim is procedurally defaulted ‘if the petitioner failed
    to exhaust state remedies and the court to which the petitioner
    would be required to present his claims in order to meet the
    exhaustion requirement would now find the claims
    procedurally barred.’” Beaty, 
    303 F.3d at 987
     (quoting
    Coleman v. Thompson, 
    501 U.S. 722
    , 735 n.1 (1991)).
    McKinney’s dual jury claims are procedurally defaulted,
    because he is barred “under Arizona law from going back to
    state court.” Id.; see also Ariz. R. Crim. P. 32.2(a), 32.4(a).6
    5
    Contrary to McKinney’s argument, the subsequent case, Harris v.
    Superior Court of the St. of Cal., Los Angeles Cnty., 
    500 F.2d 1124
    , 1126
    (9th Cir. 1974) (en banc), did not affect this portion of Williams.
    6
    Arizona Rules of Criminal Procedure 32.2(a) and 32.4(a) provide
    alternate bases for our conclusion that McKinney’s claims would now be
    barred. Rule 32.2(a)(3) precludes “any claim that could have been
    brought on direct appeal or in a prior PCR petition.” Henry v. Ryan, ___
    16                   MCKINNEY V. RYAN
    “Nonetheless, we will review the merits if [McKinney]
    can show cause and prejudice or, alternatively, a fundamental
    miscarriage of justice.” Beaty, 
    303 F.3d at 987
    . While
    McKinney mentioned these exceptions in his briefing, he
    made no argument that they apply to excuse the procedural
    default of his dual juries claims. At oral argument, when
    asked whether he could show cause, McKinney argued that
    he could establish cause under Martinez v. Ryan, 
    132 S. Ct. 1309
     (2012). McKinney’s invocation of Martinez suggests
    that McKinney argues that the ineffective assistance of his
    PCR counsel constitutes cause to overcome the procedural
    default of his other dual juries claims. However, it is well-
    settled that ineffective assistance of PCR counsel does not
    establish cause. See Coleman, 
    501 U.S. at
    753–57. While
    Martinez created a “narrow exception” to this rule, 
    132 S. Ct. at 1315
    , the Martinez exception does not apply to
    McKinney’s dual juries claims. The Supreme Court made
    clear that the exception applies only when the underlying
    constitutional claim is ineffective assistance of trial counsel.
    
    Id.
     Thus, McKinney cannot show cause and his dual juries
    claims are procedurally defaulted.
    II. “Shackling” Claim
    McKinney failed to exhaust his “shackling” claim.
    Because McKinney would now be barred from bringing the
    claim in state court, Beaty, 
    303 F.3d at 987
    , the claim is
    procedurally defaulted. McKinney has failed to show cause
    and prejudice to overcome the default.
    F.3d ___, 
    2013 WL 3027404
    , at *13 (June 19, 2013). Rule 32.4 bars
    untimely claims. See, e.g., Beaty, 
    303 F.3d at 987
    .
    MCKINNEY V. RYAN                         17
    A. Background and procedural history
    The trial court required both McKinney and Hedlund to
    wear a leg brace during trial. The trial court rejected
    Defendants’ numerous objections to the use of the leg braces.
    The trial court reasoned that the Defendants’ close proximity
    to jurors and court staff, the violent nature of the crimes, and
    evidence of McKinney’s previous escape attempt and a
    subsequent escape plot warranted the extra security measures.
    The trial court later asked the State to make a specific record
    of the security concerns. Although McKinney’s motion for
    a new trial is silent on this issue, Hedlund raised the
    “shackling” issue at the post-trial phase. Similarly,
    McKinney did not raise the “shackling” issue to the Arizona
    Supreme Court on direct appeal. However, Hedlund did raise
    the claim, which was rejected. See McKinney, 
    917 P.2d at
    1222–23. McKinney also failed to raise the issue in his PCR
    Petition.
    The district court noted that McKinney did not raise the
    “shackling” issue on direct appeal or in his PCR Petition.
    The district court rejected McKinney’s argument that the
    Arizona Supreme Court decided the issue as part of its
    “fundamental error review.” However, rather than decide that
    the claim was procedurally defaulted, the district court denied
    the claim as meritless.
    B. McKinney’s “shackling” claim is procedurally
    defaulted.
    McKinney’s “shackling” claim is not exhausted, because
    he failed to raise it to the Arizona Supreme Court or in his
    PCR Petition. As with the dual jury claims, we reject
    McKinney’s argument that the claim was exhausted by virtue
    18                      MCKINNEY V. RYAN
    of Hedlund raising it on direct appeal. See Williams,
    
    431 F.2d at
    932–33. We also reject McKinney’s argument
    that this claim was exhausted due to the Arizona Supreme
    Court’s fundamental error review. “Where the parties did not
    mention an issue in their briefs and where the court did not
    mention it was considering that issue sua sponte, there is no
    evidence that the appellate court actually considered the
    issue, regardless of its duty to review for fundamental error,
    and the issue cannot be deemed exhausted.” Moormann v.
    Schriro, 
    426 F.3d 1044
    , 1057 (9th Cir. 2005); see also
    Martinez-Villareal v. Lewis, 
    80 F.3d 1301
    , 1306 (9th Cir.
    1996) (“Under Arizona law, fundamental error review does
    not prevent subsequent procedural preclusion.”).
    This unexhausted claim is now procedurally barred,
    because McKinney would be barred from raising it to the
    state court. Beaty, 
    303 F.3d at 987
    ; see also Ariz. R. Crim. P.
    32.2(a), 32.4. Further, McKinney makes no argument for
    “cause” to excuse the default. Although McKinney makes
    numerous arguments of prejudice and injustice, he does not
    support these arguments with citations to any evidence in the
    record.7 Thus, McKinney’s “shackling” claim is procedurally
    barred.
    7
    The only evidence offered to the state court on prejudice were
    statements from members of Hedlund’s jury. Even if this evidence were
    probative of the McKinney jury’s prejudice, it actually cuts against a
    prejudice finding. While jurors clearly saw the leg brace, the only jurors
    interviewed stated that the leg brace had no bearing on their verdict.
    While not “dispositive” of the prejudice issue, see Holbrook v. Flynn,
    
    475 U.S. 560
    , 570 (1986), the jurors’ statements arguably have some
    weight. Unlike the juror statements that were given “little stock” in
    Holbrook, the jurors gave their impressions of the leg brace in this case
    after the trial was over, not during voir dire. See 
    id.
    MCKINNEY V. RYAN                               19
    III. Lockett/Eddings Claim.8
    McKinney claims that the trial court did not adequately
    consider mitigating factors in imposing the death penalty,
    thereby violating McKinney’s rights under Lockett, Eddings,
    and their progeny. McKinney argues that the trial court failed
    to consider mitigation evidence,9 finding that McKinney’s
    abusive childhood and its psychological effects did not affect
    McKinney’s “ability to perceive, comprehend or control his
    actions.” The State counters that the Arizona state courts
    fully considered all mitigating evidence and did not apply an
    unconstitutional nexus test. The State argues that the
    Lockett/Eddings line of cases holds only that a sentencer must
    fully consider proffered mitigation evidence and does not
    affect a sentencer’s determination of its weight. We agree.
    Because the record makes clear that the trial court adequately
    considered and weighed McKinney’s mitigation evidence, we
    deny relief.
    8
    The district court declined to grant a COA on this issue. However,
    because McKinney exhausted this claim and because we conclude that the
    district court’s resolution of the issue is “debatable amongst jurists of
    reason,” Miller-El v. Cockrell, 
    537 U.S. 322
    , 336 (2003), we address it.
    9
    In addition to evidence of childhood abuse and psychology, McKinney
    argues that the trial court failed to consider McKinney’s level of
    participation in the murders. He develops this argument, without citation,
    in a single sentence: “The trial judge noted there is no proof McKinney
    killed Ms. Mertens at the Hedlund sentencing but not at Mr. McKinney’s
    sentencing.” Even assuming this properly characterizes the record, the
    record elsewhere reveals that the judge specifically considered
    McKinney’s level of participation in the crimes at sentencing. The trial
    court specifically found “substantial participation in the McClain homicide
    by Mr. McKinney.”
    20                 MCKINNEY V. RYAN
    A. Background and procedural history
    McKinney had a traumatic childhood. At sentencing, the
    trial court heard evidence from McKinney’s aunt and half-
    sister of various abuses against McKinney by his father and
    step-mother. McKinney’s would-be care givers neglected
    him by forcing him to live in appalling conditions.
    McKinney did not have adequate clothing or food.
    McKinney was also frequently beaten and locked out of the
    house in extreme weather.
    The trial court also heard evidence that these abuses led
    McKinney to develop Post-Traumatic Stress Disorder
    (“PTSD”).       After administering a number of tests,
    McKinney’s expert, Dr. McMahon, testified that McKinney
    could be “emotionally overwhelmed by environmental stress
    and act in poorly-judged ways.” Dr. McMahon concluded
    that McKinney had “learning disabilities” but tested negative
    for “significant neuropsychological dysfunction.” Dr.
    McMahon testified that McKinney began abusing drugs and
    alcohol to distract him from his environmental stressors.
    Finally, Dr. McMahon opined that a sudden confrontation by
    Mertens during the course of the burglary could trigger a
    violent response from McKinney and that McKinney would
    have a “high likelihood” of diminished capacity in such an
    instance.
    The trial court credited the testimony establishing
    McKinney’s “traumatic childhood.” The trial court also
    accepted, for the purpose of sentencing, Dr. McMahon’s
    PTSD diagnosis. Nevertheless, the trial concluded:
    [A]fter considering all of the mitigating
    circumstances, the mitigating evidence that
    MCKINNEY V. RYAN                       21
    was presented by the defense in this case as
    against the aggravating circumstances, and
    other matters which clearly are not set forth in
    the statute which should be considered by a
    court, I have determined that given . . . the
    aggravating circumstances which have been
    proven beyond a reasonable doubt by the
    State with respect to each of these homicides
    in Counts I and III have concluded that the
    mitigating circumstances simply are not
    sufficiently substantial to call for a leniency
    under all the facts of this case.
    The Arizona Supreme Court rejected McKinney’s
    argument that the trial court did not adequately take into
    account McKinney’s abusive childhood and its effects.
    McKinney, 
    917 P.2d at 1234
    . The court reasoned that “the
    judge gave full consideration to McKinney’s childhood and
    the expert testimony regarding the effects of that
    childhood . . . .” 
    Id.
     The court explained that evidence of a
    traumatic childhood “does not necessarily have substantial
    mitigating weight absent a showing that it significantly
    affected or impacted the defendant’s ability to perceive,
    comprehend, or control his actions.” 
    Id.
     (emphasis added).
    The federal district court concluded that the Arizona
    Supreme Court’s decision to uphold the sentence was not
    contrary to, nor an unreasonable application of,
    Lockett/Eddings.
    22                     MCKINNEY V. RYAN
    B. McKinney has failed to show that the Arizona
    Supreme Court unreasonably applied Lockett/Eddings.
    In Lockett, the Supreme Court held:
    [T]he Eighth and Fourteenth Amendments
    require that the sentencer . . . not be precluded
    from considering, as a mitigating factor, any
    aspect of a defendant’s character or record
    and any of the circumstances of the offense
    that the defendant proffers as a basis for a
    sentence less than death. . . .
    Given that the imposition of death by public
    authority is . . . profoundly different from all
    other penalties, . . . [the sentencer must be free
    to give] independent mitigating weight to
    aspects of the defendant’s character and
    record and to circumstances of the offense
    proffered in mitigation . . . .
    
    438 U.S. at
    604–05 (finding Ohio death penalty statute
    invalid where it permitted consideration of only three
    mitigating circumstances).
    Later, in Eddings, the Supreme Court applied Lockett in
    a case where the trial judge found he could not consider in
    mitigation evidence of the defendant’s family history.10
    10
    In Eddings, the sentencing judge made clear, on the record, that he
    could not consider certain evidence as a matter of law. He stated: “[T]he
    Court cannot be persuaded entirely by the . . . fact that the youth was
    MCKINNEY V. RYAN                              23
    
    455 U.S. at
    112–13. The appeals court affirmed the trial
    court, finding that the mitigation evidence was “not relevant
    because it did not tend to provide a legal excuse” for
    responsibility for the crime. 
    Id. at 113
    . The Supreme Court
    reversed, explaining that “[j]ust as the State may not by
    statute preclude the sentencer from considering any
    mitigating factor, neither may the sentencer refuse to
    consider, as a matter of law, any relevant mitigating
    evidence. . . .The sentencer . . . may determine the weight to
    be given relevant mitigating evidence. But they may not give
    it no weight by excluding such evidence from their
    consideration.” 
    Id.
     at 113–15.
    In Tennard v. Dretke, the Supreme Court rejected a
    “nexus test” that would find mitigating evidence relevant only
    where it bears a causal nexus to the crime. 
    542 U.S. 274
    , 287
    (2004) (“[W]e cannot countenance the suggestion that low IQ
    evidence is not relevant mitigating evidence . . . unless the
    defendant also establishes a nexus to the crime.”). Citing
    Lockett and Eddings, the Court cautioned that the jury must
    be given an effective vehicle with which to weigh mitigating
    evidence so long as the defendant has met a “low threshold
    for relevance,” which is satisfied by “evidence which tends
    logically to prove or disprove some fact or circumstance
    which a fact-finder could reasonably deem to have mitigating
    value.” 
    Id.
     at 284–85.
    In Smith v. Texas, the Court again considered the use of
    a nexus test to determine whether mitigating evidence is
    relevant. 
    543 U.S. 37
    , 45 (2004). The Court “unequivocally
    sixteen years old when this heinous crime was committed. Nor can the
    Court in following the law, in my opinion, consider the fact of this young
    man’s violent background.” 
    455 U.S. at 109
     (alterations in original).
    24                   MCKINNEY V. RYAN
    rejected” any test requiring a causal nexus between mitigating
    evidence and the crime. 
    Id.
    We have held that Tennard and Smith are retroactively
    applicable to decisions such as the Arizona Supreme Court’s
    1996 decision in this case. See Schad v. Ryan, 
    671 F.3d 708
    ,
    723 (9th Cir. 2009) (per curiam), cert. denied, 
    133 S. Ct. 432
    (2012). Thus, under clearly established federal law, we
    review (1) whether the trial court considered all relevant
    mitigating evidence, as required by Lockett and Eddings; and,
    (2) whether the Arizona Supreme Court applied an
    unconstitutional causal nexus test to exclude evidence
    proffered in mitigation, contrary to Tennard and Smith.
    In this case, the Arizona courts did not improperly
    exclude any of McKinney’s mitigating evidence. Further, the
    Arizona courts did not employ an unconstitutional nexus test.
    Thus, the Arizona Supreme Court’s decision to affirm
    McKinney’s sentence was not contrary to, nor an
    unreasonable application of, clearly established federal law.
    1. All mitigating evidence was considered as required
    by Eddings.
    The Arizona Supreme Court did not violate Eddings when
    it concluded that the trial court considered all the mitigation
    evidence before it. The Arizona Supreme Court clearly
    understood and applied the controlling Supreme Court
    precedent. See McKinney, 
    917 P.2d at 1227
    . It concluded:
    “[T]he judge considered McKinney’s abusive childhood and
    its impact on his behavior and ability to conform his conduct
    and found it insufficiently mitigating to call for leniency.” 
    Id. at 1234
     (emphasis added)). The Arizona Supreme Court did
    MCKINNEY V. RYAN                                25
    not say that the evidence was irrelevant or could not be
    considered.11 
    Id.
    We reject McKinney’s and the dissent’s implication that
    the Arizona Supreme Court’s decision merely paid lip service
    to Eddings, and the trial judge did not actually consider the
    evidence. As an initial matter, the trial court’s certification
    that it considered all the mitigation evidence is entitled to
    some weight. See Lopez, 
    491 F.3d at 1037
     (“‘We must
    assume that the trial judge considered all this evidence before
    passing sentence. For one thing, he said he did.’” (quoting
    Parker v. Dugger, 
    498 U.S. 308
    , 314 (1991))). In addition,
    the record shows that the trial court’s commitment to Eddings
    was more than semantic—the trial judge genuinely weighed
    the mitigation evidence’s persuasive value. The trial judge
    expressly credited the evidence of childhood abuse,
    describing it as “beyond the comprehension and
    understanding of most people who have not grown up under
    those circumstances.” The trial court also accepted, for the
    purpose of sentencing, Dr. McMahon’s PTSD diagnosis.
    Further, even when the court discussed the possible link
    between McKinney’s PTSD and the crimes, the record shows
    that it considered all the evidence and weighed the evidence’s
    probative value. The trial judge stated:
    I found it interesting Dr. McMahon also
    indicated that one of the techniques—or the
    11
    Other cases pre-dating or contemporaneous with McKinney also
    demonstrate that the Arizona Supreme Court was well-aware of the
    Lockett/Eddings line of cases and the requirement that the sentencing court
    fully consider all mitigating evidence. See, e.g., State v. Towery, 
    920 P.2d 290
    , 310–11 (Ariz. 1996) (en banc); State v. Gonzales, 
    892 P.2d 838
    , 851
    (Ariz. 1995) (en banc).
    26                      MCKINNEY V. RYAN
    manifestations of Post-traumatic Stress
    Syndrome that might be expected were that
    the individual be depressed, would be
    withdrawn. It appears to me that defense
    attempted to demonstrate that in their
    presentation of mitigating circumstances and
    that such an individual would expect to avoid
    contacts which would either exacerbate or
    recreate the trauma that would bring on this
    type of stress from childhood. And yet, rather
    than continue to avoid any of these
    circumstances after the Mertens homicide, it
    appears that the same thoughtful, reflective
    planning went into, then, the burglary of a
    known target to both the defendant and the co-
    defendant, Mr. McClain.
    Other portions of the sentencing transcript similarly
    demonstrate the judge’s deliberative process as he considered
    the PTSD evidence and weighed it against the other evidence
    presented. This careful analysis of Dr. McMahon’s testimony
    contradicts McKinney’s and the dissent’s claim that the
    sentencing judge excluded the evidence, or refused to
    consider it, as a matter of law.12
    12
    This obvious deliberation is in sharp contrast to the sentencing court
    record in Towery. In that case, we upheld the Arizona Supreme Court’s
    decision to deny relief under Eddings despite some language in the
    sentencing transcript indicating that mitigating evidence was excluded, or
    not considered. See 673 F.3d at 936–37, 946–47. For example, the
    sentencing judge stated: “[A] difficult family background in and of itself,
    is not a mitigating circumstance.” Id. at 936. The sentencing court went
    on to explain that “[a] difficult family background is a relevant mitigating
    circumstance, if a defendant can show that something in that background
    had an [e]ffect or impact on his behavior that was beyond the defendant’s
    MCKINNEY V. RYAN                               27
    The dissent selectively quotes passages from the
    sentencing transcript to argue that the Arizona state courts did
    not properly consider evidence of PTSD. There are two
    problems with the dissent’s approach. First, it reads too much
    into certain passages, notably the sentencing judge’s
    discussion of the psychological study submitted as Exhibit 3.
    Contrary to the dissent’s view, nothing in the sentencing
    judge’s discussion of PTSD shows that he believed it was
    “irrelevant” as a matter of law. At most, the discussion of
    PTSD shows that the sentencing judge was equivocal about
    what effect in mitigation the PTSD diagnosis should have.
    This strengthens the conclusion that the sentencing judge
    considered the evidence and did not simply exclude it.
    However, even if the sentencing judge created some
    ambiguity in the record by “thinking out loud” as he
    considered the PTSD evidence, that ambiguity should be cast
    in favor of the state. See Poyson v. Ryan, 
    711 F.3d 1087
    ,
    1099 (9th Cir. 2013).
    Similarly, the dissent overlooks passages where the
    sentencing judge clearly stated that he considered “all of the
    mitigating circumstances.” Contrary to the dissent’s view, we
    do not fail to take into account the difference between the
    sentencing judge’s treatment of the PTSD and other
    mitigation evidence. There is no difference in treatment. The
    record clearly shows the sentencing judge’s deliberation as he
    considered each piece of mitigation evidence. Thus, the
    record as a whole contradicts the dissent’s view that the
    control.” 
    Id.
     (emphasis added) (second alteration in original). Here, the
    record makes clear that both the sentencing court and the Arizona
    Supreme Court fully considered all mitigating evidence. Thus, the proper
    resolution of the Eddings issue in this case is even clearer than it was in
    Towery.
    28                  MCKINNEY V. RYAN
    Arizona state courts rejected the PTSD evidence as a matter
    of law.
    Because the record shows that the sentencing judge
    considered all the potential mitigation evidence, we reject
    McKinney’s and the dissent’s reliance on a number of our
    past cases granting relief. See, e.g., Williams v. Ryan,
    
    623 F.3d 1258
     (9th Cir. 2010); Styers v. Schriro, 
    547 F.3d 1026
    , 1035–36 (9th Cir. 2008); Lambright v. Schriro,
    
    490 F.3d 1103
    , 1115 (9th Cir. 2007). Those cases provide
    little guidance to inform our AEDPA review. For example,
    in Williams, we granted relief under Lockett/Eddings.
    However, unlike the state courts here, the state courts in
    Williams held that the mitigating evidence “could not be
    considered as a mitigating factor of any kind.” 
    623 F.3d. at 1270
     (internal quotation marks omitted). This statement
    resembles the clear statement from Eddings that the trial
    judge excluded mitigation evidence as a matter of law. See
    Eddings, 
    455 U.S. at 109
    . Styers and Lambright, also cited
    by McKinney and the dissent, contain similar statements. See
    Styers, 
    547 F.3d at
    1035–36 (granting relief under Eddings
    where Arizona Supreme Court analysis made clear that
    mitigating evidence was not considered); Lambright,
    
    490 F.3d at 1115
     (granting relief under Lockett where the trial
    court did not consider “any evidence without an explicit
    nexus to the crime, or . . . gave such evidence de minim[i]s
    weight”).
    The record in this case does not contain the same clear
    statement of exclusion that appears in those cases, rendering
    them inapposite. See Schad, 671 F.3d at 724 (distinguishing
    Styers and Lambright, because “[i]n both of those cases . . .
    it was clear from the record that the lower court had applied
    the unconstitutional nexus test and had excluded mitigation
    MCKINNEY V. RYAN                               29
    evidence” (emphasis added)). We will not second-guess the
    Arizona state courts’ application of Eddings where the record
    shows that the courts considered and weighed all mitigation
    evidence13 and did not make a clear, affirmative statement of
    exclusion. See id. (“Absent a clear indication in the record
    that the state court applied the wrong standard, we cannot
    assume the courts violated Eddings’s constitutional
    mandates.”); see also Lopez, 
    491 F.3d at
    1036–38 (denying
    relief under Eddings where “the sentencing court did not
    prevent [the petitioner] from presenting any evidence in
    mitigation, nor did it affirmatively indicate that there was any
    evidence it would not consider”).
    13
    The dissent argues that the Arizona Supreme Court’s conclusion that
    the sentencing judge “gave full consideration to” McKinney’s PTSD
    evidence, see McKinney, 
    917 P.2d at 1234
    , was based on an unreasonable
    determination of fact under § 2254(d)(2). The dissent also argues that the
    sentencing judge never accepted Dr. McMahon’s PTSD diagnosis, nor
    made a finding of PTSD, which tainted the Arizona Supreme Court’s
    review.
    As demonstrated above, the record contradicts both arguments. As
    the dissent acknowledges, “the sentencing judge did quite a bit of talking
    about PTSD . . . .” This discussion demonstrates the sentencing judge’s
    deliberative process—his weighing of the evidence. There would have
    been little need to do so much “talking” about the PTSD diagnosis if he
    planned to exclude it as a matter of law. Further, the record demonstrates
    that the sentencing judge assumed that the PTSD diagnosis was true.
    Nothing required the sentencing judge to make a particular finding that the
    diagnosis was accurate, because the record shows that he was able to
    adequately weigh the evidence by assuming that it was true.
    30                  MCKINNEY V. RYAN
    2. The Arizona Supreme Court did not apply an
    unconstitutional nexus test to McKinney’s
    mitigating evidence.
    As we have previously recognized, state courts are free to
    consider a nexus to determine the weight to give mitigation
    evidence. See Schad, 671 F.3d at 723 (“The United States
    Supreme Court has said that the use of the nexus test in this
    manner is not unconstitutional because state courts are free to
    assess the weight to be given to particular mitigating
    evidence.”). For example, we upheld the Arizona Supreme
    Court’s exercise of this discretion in Towery v. Ryan,
    
    673 F.3d 933
    , 944–45 (9th Cir. 2012), cert. denied,
    
    132 S. Ct. 1738
     (2012). In Towery, we reviewed the Arizona
    Supreme Court’s rulings that (1) the sentencing court “must
    consider the defendant’s upbringing if proffered but is not
    required to give it significant mitigating weight” and (2) the
    question of “[h]ow much weight should be given proffered
    mitigating factors is a matter within the sound discretion of
    the sentencing judge.” 
    Id. at 938
    . We concluded that these
    were “correct statements of the law.” 
    Id. at 944
    . We also
    affirmed the ruling that “a difficult family background is not
    always entitled to great weight as a mitigating circumstance,”
    and “where the defendant fails to connect his family
    background to his criminal conduct, a trial judge could give
    it little or no weight or value.” 
    Id.
     at 944–45.
    Here, like in Towery, the Arizona Supreme Court
    concluded that “a difficult family background, including
    childhood abuse, does not necessarily have substantial
    mitigating weight absent a showing that it significantly
    affected or impacted the defendant’s ability to perceive,
    comprehend, or control his actions.” McKinney, 
    917 P.2d at 1234
    . While the Arizona Supreme Court ultimately decided
    MCKINNEY V. RYAN                                31
    that the cumulative weight of the mitigating evidence did not
    call for leniency, the court based this conclusion on the
    weight assigned to mitigating factors. Nothing in the record
    suggests that the Arizona Supreme Court outrightly rejected,
    or otherwise did not fully consider, those factors due to a lack
    of nexus to the crime. Accordingly, the Arizona Supreme
    Court did not apply an unconstitutional nexus test when it
    affirmed the sentencing court’s exercise of discretion over the
    weight to assign the evidence that it considered.
    We reject the dissent’s argument that other Arizona
    Supreme Court cases applying an unconstitutional nexus test
    demonstrate that the Arizona Supreme Court “followed suit”
    in this case. We have formerly rejected the argument that
    “the Arizona Supreme Court’s historical use of an
    unconstitutional causal nexus test” creates a presumption of
    error. See Poyson, 711 F.3d at 1099. Any such presumption
    would be especially inappropriate here, because the Arizona
    Supreme Court’s decision makes clear that it did not apply an
    unconstitutional nexus test.14
    McKinney makes much of the Arizona Supreme Court’s
    citation to State v. Ross, 
    886 P.2d 1354
     (Ariz. 1994). In Ross,
    the Arizona Supreme Court stated “[a] difficult family
    background is not a relevant mitigating circumstance unless
    ‘a defendant can show that something in that background had
    an effect or impact on his behavior that was beyond the
    defendant’s control.’” 
    Id. at 1363
     (emphasis added) (quoting
    14
    We also reject the dissent’s view that the sentencing court (as distinct
    from the Arizona Supreme Court) impermissibly applied a causal nexus
    test. As discussed above, the record makes clear that the sentencing court
    did not exclude any evidence due to a lack of causal nexus to the crime,
    or for any other reason.
    32                    MCKINNEY V. RYAN
    State v. Wallace, 
    773 P.2d 983
    , 986 (Ariz. 1989)). McKinney
    argues that the Arizona Supreme Court’s citation to Ross
    demonstrates that it held the mitigation evidence irrelevant
    and unconstitutionally excluded it for its lack of causal nexus
    to the crime.
    We reject this argument, just as we rejected a similar
    argument in Towery, where the Arizona Supreme Court
    supported its decision with a citation to Wallace. See Towery,
    673 F.3d at 946. While the Towery court deemed Wallace
    (and, by extension, Ross) “constitutionally suspect,” this does
    not end the analysis. See id. We must review the record in
    McKinney’s case to determine whether the sentencing court
    and the Arizona Supreme Court actually applied the
    unconstitutional test. See id. For the reasons stated above,
    we conclude that the Arizona Supreme Court did not apply an
    unconstitutional nexus test, notwithstanding the citation to
    Ross.15 Thus, McKinney has failed to establish that the
    Arizona Supreme Court’s decision to uphold the trial court
    was contrary to, or an unreasonable application of,
    Lockett/Eddings.
    CONCLUSION
    The district court properly denied relief on McKinney’s
    “courtroom layout” and Lockett/Eddings claims, because the
    Arizona Supreme Court’s decision denying relief was not
    contrary to, nor an unreasonable application of, clearly
    established federal law or based on an unreasonable
    15
    At least one Arizona Supreme Court case decided after McKinney
    recognizes that McKinney discussed “weighing” the mitigating evidence,
    notwithstanding McKinney’s citation to Ross. See State v. Greene,
    
    967 P.2d 106
    , 118 (Ariz. 1998) (en banc).
    MCKINNEY V. RYAN                                33
    determination of the facts. The district court also properly
    denied relief on McKinney’s remaining dual juries and
    “shackling”claims, because the claims are procedurally
    defaulted.
    AFFIRMED.16
    WARDLAW, Circuit Judge, concurring in part and dissenting
    in part:
    Because McKinney failed to exhaust the dual juries and
    shackling claims, I agree with the majority’s conclusion that
    denial of relief on these claims must be upheld. However, I
    disagree with its analysis of McKinney’s Eddings claim1 and,
    therefore, dissent from Part III of the majority’s opinion. It
    is clear from the record that the sentencing judge improperly
    refused to consider the mitigating effect of McKinney’s post
    traumatic stress disorder (“PTSD”) evidence specifically
    because the judge concluded that this evidence was not
    causally linked to McKinney’s crimes, contrary to the U.S.
    Supreme Court’s decisions in Eddings and its progeny. The
    Arizona Supreme Court repeated that legal error, resulting in
    16
    On December 3, 2012, McKinney filed a “Motion to File Late
    Supplemental Authorities.” While we see no reason that these authorities
    could not have been presented in a 28(j) letter, we nevertheless “grant” the
    motion. However, none of the authorities referenced provide any basis for
    relief under AEDPA.
    1
    The panel majority agrees that we should address McKinney’s
    uncertified Lockett/Eddings claim because the resolution of this issue is
    “debatable amongst jurists of reason.” Miller-El v. Cockrell, 
    537 U.S. 322
    , 330 (2003).
    34                  MCKINNEY V. RYAN
    a decision that “was contrary to . . . clearly established
    Federal law, as determined by the Supreme Court of the
    United States.” 
    28 U.S.C. § 2254
    (d)(1). Further, the Arizona
    Supreme Court’s characterization of the sentencing judge’s
    decision was factually inaccurate, resulting “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)(2). McKinney has demonstrated that he
    is entitled to habeas relief regardless of whether Eddings
    violations are deemed structural error or are reviewed for
    harmless error. I would therefore reverse the district court’s
    denial of all relief and remand with instructions to grant
    McKinney’s habeas petition based on this claim.
    I.
    It was well established in 1993, when McKinney was
    sentenced, that “[j]ust as the State may not by statute preclude
    the sentencer from considering any mitigating factor, neither
    may the sentencer refuse to consider, as a matter of law, any
    relevant mitigating evidence.” Eddings v. Oklahoma,
    
    455 U.S. 104
    , 113–14 (1982). The Supreme Court has
    clarified that the Eighth and Fourteenth Amendments
    specifically require the sentencer to fully consider all
    mitigating evidence, regardless of the lack of a causal
    connection between the evidence and the defendant’s crime
    of conviction:
    There is no disputing that this Court’s
    decision in Eddings requires that in capital
    cases the sentencer . . . not be precluded from
    considering, as a mitigating factor, any aspect
    of a defendant’s character or record and any
    of the circumstances of the offense that the
    MCKINNEY V. RYAN                       35
    defendant proffers as a basis for a sentence
    less than death. Equally clear is the corollary
    rule that the sentencer may not refuse to
    consider or be precluded from considering any
    relevant mitigating evidence. These rules are
    now well established . . . .
    Skipper v. South Carolina, 
    476 U.S. 1
    , 4 (1986) (internal
    quotation marks and citations omitted) (emphasis added); see
    also Eddings, 
    455 U.S. at 110
    . In Smith v. Texas, 
    543 U.S. 37
    (2004), the Court explained that such causal “nexus
    requirements” are “a test we never countenanced and now
    have unequivocally rejected.” 
    Id.
     at 45 (citing Eddings,
    
    455 U.S. at 114
    ); see also Smith, 
    543 U.S. at 45
     (holding that
    it was “plain under [Supreme Court] precedents” that
    evidence lacking a “nexus” to the crime of conviction “was
    relevant for mitigation purposes”).         Accordingly, the
    Constitution forbids sentencers in capital cases from refusing
    to consider any mitigating evidence on the basis that the
    evidence lacks a nexus to a defendant’s crime of conviction.
    It was also well established when McKinney was
    sentenced that Eddings and its progeny require that the
    sentencer give “independent mitigating weight” to all relevant
    mitigating evidence. See Eddings, 
    455 U.S. at 110
    . This has
    been a cornerstone of the Supreme Court’s jurisprudence
    since Lockett was decided in 1978:
    [A] statute that prevents the sentencer in all
    capital cases from giving independent
    mitigating weight to aspects of the defendant’s
    character and record and to circumstances of
    the offense proffered in mitigation creates the
    risk that the death penalty will be imposed in
    36                  MCKINNEY V. RYAN
    spite of factors which may call for a less
    severe penalty. When the choice is between
    life and death, that risk is unacceptable and
    incompatible with the commands of the
    Eighth and Fourteenth Amendments.
    Lockett v. Ohio, 
    438 U.S. 586
    , 605 (1978) (emphasis added).
    The Court has recognized that the sentencer must perform an
    individualized analysis of each piece of relevant mitigating
    evidence: “the sentencer must be free to give ‘independent
    mitigating weight to aspects of the defendant’s character and
    record and to circumstances of the offense proffered in
    mitigation . . . .’” Eddings, 
    455 U.S. at 110
     (quoting Lockett,
    
    438 U.S. at 605
    ). Supreme Court precedent thus requires the
    sentencer to give adequate and independent consideration to
    all relevant evidence that a defendant proffers in mitigation
    of his crimes.
    Finally, the rule announced in Eddings requires that the
    sentencer actually consider each independent piece of
    relevant mitigating evidence. See Eddings, 
    455 U.S. at 113
    .
    Lockett and Eddings both emphasize the significance of “the
    type of individualized consideration of mitigating factors”
    required by the Eighth and Fourteenth Amendments. See
    Eddings, 
    455 U.S. at 105
    ; Lockett, 
    438 U.S. at 606
    .
    Certainly, the appropriate degree of care or caution that must
    be accorded to each independent piece of mitigating evidence
    will vary. See Webster’s Third New International Dictionary
    483 (1986) (defining “consider” as “to reflect on: think about
    with a degree of care or caution”). However, it is clear that
    whether a sentencer “said he did” enough to comply with the
    Constitution is irrelevant for constitutional purposes; the true
    test is whether the sentencer actually exercised “the type of
    MCKINNEY V. RYAN                       37
    individualized consideration” required by the Constitution.
    Eddings, 
    455 U.S. at 105
    .
    II.
    McKinney argued at sentencing that he should not be
    sentenced to death due to his difficult childhood, alcohol
    addiction, good behavior while incarcerated, and residual
    doubt concerning his role in the offenses. In addition,
    McKinney specifically raised his PTSD diagnosis as a
    mitigating factor independent of the underlying childhood
    trauma he suffered and as a factor to be given separate weight
    at sentencing.
    As support for imposition of a noncapital sentence,
    McKinney presented evidence at sentencing as to what even
    the sentencing judge found to be an “extraordinary” and
    “traumatic childhood,” which would be “beyond the
    comprehension and understanding of most people . . . .”
    Sentencing Hr’g Tr. at 26, July 23, 1993. McKinney’s sister,
    Diana McKinney, and aunt, Susan Sestate, both testified at
    length concerning McKinney’s horrific childhood. They
    testified that McKinney grew up in extreme poverty, living in
    filth, lacking adequate clothing, and suffering constant
    physical and emotional abuse, largely at the hands of his
    stepmother. He and his three siblings shared a single
    bedroom and were expected to do all of the cleaning and
    cooking in the home. McKinney consistently arrived at
    school poorly dressed, dirty, and covered in welts and bruises
    from beatings he received at home. Unsurprisingly,
    McKinney ran away repeatedly, appearing at the homes of
    relatives and friends bearing signs that he had been beaten.
    The sentencing judge found this testimony credible,
    determining that as a child McKinney was “abused, beaten,
    38                  MCKINNEY V. RYAN
    and deprived of the necessary care, clothing, and parental
    love and affection.”
    In addition to enduring a horrific childhood, as an adult
    McKinney suffered serious psychological problems. At
    sentencing, Dr. Mickey McMahon, a clinical psychologist,
    testified to his opinion that McKinney suffered from PTSD,
    writing in his expert report that McKinney “underwent a
    massive amount of neglect and abuse during his
    developmental years which in my opinion was sufficient to
    create a case of Post-Traumatic Stress Disorder.” Dr.
    McMahon also described numerous ways in which this
    disorder could have affected McKinney and impaired his
    ability to control his behavior on the nights of the murders.
    Specifically, Dr. McMahon testified that McKinney’s PTSD
    may have caused him to have a “reflexive” and “emotional”
    response to any confrontation during the burglary, which
    could have led to his having “diminished capacity” at the time
    of the murders. Dr. McMahon concluded by testifying that he
    had no doubt that McKinney suffered from PTSD. In
    addition to Dr. McMahon’s testimony that McKinney
    suffered from PTSD, another doctor testified on McKinney’s
    behalf concerning his below-average intelligence.
    Despite this evidence, the sentencing judge refused to
    give McKinney’s PTSD diagnosis any weight in mitigation
    because McKinney failed to show that the PTSD had any
    direct effect on his crimes. In fact, the sentencing judge
    declined even to make a finding as to whether McKinney
    actually suffered from PTSD because he concluded that this
    was irrelevant to his sentencing decision. The sentencing
    judge initially discussed McKinney’s PTSD in two sentences,
    which, although nearly incoherent, express the view that the
    expert’s PTSD diagnosis was, at a minimum, suspect:
    MCKINNEY V. RYAN                       39
    However, in viewing Exhibit 3, which defense
    introduced and Dr. McMahon acknowledged
    either reviewing or relying upon, it appeared
    that in reviewing that exhibit that even those
    experts who agree that Post-traumatic Stress
    Syndrome can result from childhood abuse
    and be a lingering problem of individuals who
    have been abused, beaten and deprived of the
    necessary care, clothing, and parental love and
    affection that Mr. McKinney was – obviously,
    through the testimony, was deprived of in this
    case – nevertheless have concluded as Dr.
    McMahon indicated, there was a cognitive
    impairment of the defendant. There was no
    evidence presented of any organic brain
    damage or disease of the defendant; that in
    Exhibit 3, it appears at least in the sample of
    individuals in that case and comparing those
    individuals with cognitive impairment, with
    abuse, where there was not psychotic episodes
    or neurological damage to a defendant, where
    at least two or three of those things were
    present, that if only cognitive impairment and
    abuse were present, if there was nothing
    significantly significant in the violent offenses
    expected to be committed by those
    individuals, the experts found that there was
    no significant difference between an
    individual with cognitive impairment who
    suffered with child abuse with no history of
    cognitive abuse or those who had only been
    abused or only had a cognitive deficit.
    Sentencing Hr’g Tr. at 27–28, July 23, 1993.
    40                   MCKINNEY V. RYAN
    Exhibit 3, to which the sentencing judge refers, is a paper
    prepared in 1989 by researchers at the New York University
    School of Medicine, Department of Psychiatry, which
    attempts to predict which violent delinquents will go on to
    commit adult aggressive offenses. Dorothy Otnow Lewis,
    M.D. et al., Toward a Theory of the Genesis of Violence: A
    Follow-up Study of Delinquents, 28 J. AM. ACAD. CHILD &
    ADOLESCENT PSYCHIATRY 431 (1989). The paper concludes
    that “a constellation of interacting clinical and environmental
    variables is a far better predictor of future violent behavior
    than is early aggression alone.” Id. at 436. In this passage of
    the sentencing transcript, the sentencing judge is stating that
    because there was no evidence that McKinney suffered
    certain of the clinical variables identified in the paper, i.e. a
    psychotic episode or neurological damage, there was no
    correlation between his diagnosis of PTSD and the
    commission of his crimes. And because the sentencing judge
    so concluded, he unconstitutionally screened out PTSD as a
    matter of law, before it could be weighed along with the other
    mitigating and aggravating factors. Of course, doing so was
    nonsensical as well, because the study only purports to
    predict which abused adolescents will become violent adults
    who commit murder. At this point, McKinney had been
    convicted of two murders, so he had already committed what
    the paper describes as “the most serious of crimes.” Id. at
    435. The issue for the sentencing judge was not whether
    McKinney’s crimes were predictable; it was whether the fact
    that McKinney suffered from PTSD reduced his culpability
    for the murders—an issue the judge declined to address
    because his reading of the study caused him to conclude that
    the PTSD diagnosis was not causally related to McKinney’s
    crimes.
    MCKINNEY V. RYAN                      41
    Having done so, the sentencing judge explicitly declined
    to make a finding as to whether McKinney actually suffered
    from PTSD, because he viewed this as irrelevant given the
    lack of a nexus between the PTSD and McKinney’s crimes:
    But, I think more importantly than that,
    certainly not trying to dispute him as an
    expert on what all that meant, it appeared to
    me that Dr. McMahon did not at any time
    suggest in his testimony nor did I find any
    credible evidence to suggest that, even if the
    diagnoses of Post-traumatic Stress Syndrome
    were accurate in Mr. McKinney’s case, that in
    any way significantly impaired Mr.
    McKinney’s conduct.
    Sentencing Hr’g Tr. at 28 (emphasis added). If this
    articulation of an impermissible nexus test were not clear
    enough, the sentencing judge next confirmed that he excluded
    the PTSD evidence from his mitigation analysis because there
    was no evidence linking the PTSD to McKinney’s criminal
    conduct:
    [I]t appeared to me that based upon all these
    circumstances that there simply was no
    substantial reason to believe that even if the
    trauma that Mr. McKinney had suffered in
    childhood had contributed to an appropriate
    diagnosis of Post-traumatic Stress Syndrome
    that it in any way affected his conduct in this
    case.
    Id. at 29. The sentencing judge reaffirmed for a third time
    that he excluded the PTSD diagnosis from his consideration
    42                  MCKINNEY V. RYAN
    of whether to sentence McKinney to life or death because he
    did not believe this evidence had a causal relationship with
    McKinney’s crimes under Arizona’s death penalty statute:
    I’ve determined that even though there may
    be some evidence by Dr. McMahon that
    would demonstrate under [
    Ariz. Rev. Stat. Ann. § 13
    –751](G)(1) a capacity by the
    defendant to appreciate the wrongfulness of
    conduct, it was not significantly impaired,
    either by the use of drugs, alcohol or the
    possibility of a diagnosis of Post-traumatic
    Stress Syndrome.
    
    Id. at 30
    . There can be no doubt that the sentencing judge
    disposed of McKinney’s PTSD diagnosis by concluding that
    its validity was irrelevant because the lack of a nexus between
    the PTSD and McKinney’s criminal conduct made it
    nonmitigating as a matter of law. As discussed more fully
    below, McKinney presented this evidence for two reasons: to
    suggest that he had diminished capacity on the night of the
    murders and to demonstrate that he was less culpable for his
    crimes than someone who did not suffer from PTSD. The
    sentencing judge addressed the first argument, finding that
    McKinney’s capacity was not diminished. However, he
    failed to address whether the PTSD diagnosis had any impact
    on McKinney’s culpability for his crimes. This serious
    Eddings/Lockett error violated the Eighth and Fourteenth
    Amendments.
    MCKINNEY V. RYAN                               43
    III.
    On direct appeal, the Arizona Supreme Court2 agreed with
    the sentencing judge that the absence of a causal relationship
    between McKinney’s PTSD diagnosis and his crimes
    rendered this evidence nonmitigating as a matter of law.
    Thus, the Arizona Supreme Court’s decision was “contrary to
    . . . clearly established Federal law, as determined by the
    Supreme Court of the United States.”               
    28 U.S.C. § 2254
    (d)(1). In addition, the Arizona Supreme Court failed
    to accurately describe or analyze the sentencing judge’s
    rationale in sentencing McKinney. As a result, the Arizona
    Supreme Court’s decision also was “based on an
    unreasonable determination of the facts” under 
    28 U.S.C. § 2254
    (d)(2). These legal and factual errors satisfy
    § 2254(d), entitling McKinney to habeas relief under
    AEDPA.
    First, the Arizona Supreme Court’s opinion repeats the
    sentencing judge’s unconstitutional treatment of McKinney’s
    PTSD diagnosis:
    [T]he record shows that the judge gave full
    consideration to McKinney’s childhood and
    the expert testimony regarding the effects of
    that childhood, specifically the diagnosis of
    post-traumatic stress disorder (PTSD).
    2
    As Judge Thomas makes eminently clear in his dissent in Poyson v.
    Ryan, 
    711 F.3d 1087
     (9th Cir. 2013), “At the time it decided this case, the
    Arizona Supreme Court applied a causal nexus test similar to the one the
    U.S. Supreme Court held unconstitutional in Tennard [v. Dretke, 
    542 U.S. 274
     (2004)].” Poyson, 711 F.3d at 1105 (Thomas, J., dissenting) (listing
    Arizona cases).
    44                      MCKINNEY V. RYAN
    Assuming the diagnoses were correct, the
    judge found that none of the experts testified
    to, and none of the evidence showed, that such
    conditions in any way significantly impaired
    McKinney’s ability to conform his conduct to
    the law.
    State v. McKinney, 
    917 P.2d 1214
    , 1234 (Ariz. 1996)
    (emphasis added). In doing so, the court agreed with the
    sentencing judge that McKinney’s PTSD evidence was
    nonmitigating as a matter of law because McKinney failed to
    show a relationship between the diagnosis and his crimes. As
    discussed above, this was contrary to then-clearly established
    constitutional law and therefore meets the requirements of
    § 2254(d)(1).3
    Second, the Arizona Supreme Court’s decision was based
    on two independent “unreasonable determination[s] of the
    facts in light of the evidence presented in the State court
    proceeding.” 
    28 U.S.C. § 2254
    (d)(2). Contrary to the court’s
    3
    In concluding that the “Arizona Supreme Court did not apply an
    unconstitutional nexus test to McKinney’s mitigating evidence,” the
    majority fails to distinguish between Arizona’s unconstitutional treatment
    of McKinney’s PTSD diagnosis and its permissible treatment of other
    mitigation evidence. However, we have never held that a state’s
    permissible treatment of some mitigation evidence can somehow “cure”
    the unconstitutional treatment of other mitigating evidence. Nor could we
    have, as Eddings and Lockett make clear that the Eighth and Fourteenth
    Amendments require that all relevant evidence must be given
    “independent mitigating weight.” Eddings, 
    455 U.S. at 110
     (emphasis
    added). Therefore, it is irrelevant for constitutional purposes that the
    sentencing judge adequately considered some of McKinney’s mitigation
    evidence; that he failed to adequately consider independently the PTSD
    diagnosis is sufficient to establish that McKinney is entitled to habeas
    relief.
    MCKINNEY V. RYAN                         45
    bald statements, the sentencing judge never “gave full
    consideration to” McKinney’s PTSD diagnosis as a possible
    mitigating factor favoring a life sentence over death.
    McKinney, 
    917 P.2d at 1234
    . In fact, while the sentencing
    judge did quite a bit of talking about PTSD, much of this
    discussion related to the predictive analysis in Exhibit 3 as his
    reason for screening out the PTSD diagnosis as a mitigating
    factor, and refusing to weigh it with other relevant factors.
    Certainly, nothing in the record indicates that the sentencing
    judge exercised “the type of individualized consideration of
    mitigating factors . . . required by the Eighth and Fourteenth
    Amendments.” Eddings, 
    455 U.S. at 105
     (quoting Lockett,
    
    438 U.S. at 606
    ). Instead, the sentencing judge only
    “considered” McKinney’s PTSD evidence in the sense that he
    determined that there was no causal relationship between it
    and McKinney’s crimes. As discussed above, this is
    insufficient under Eddings and Lockett. Thus, the Arizona
    Supreme Court’s decision was based on the unreasonable
    factual determination that the sentencing judge fully
    considered McKinney’s PTSD evidence as a mitigating
    factor. This factual error satisfies § 2254(d)(2).
    The Arizona Supreme Court’s second unreasonable
    factual determination concerns the sentencing judge’s refusal
    to accept McKinney’s PTSD diagnosis for sentencing
    purposes. While the sentencing judge expressly declined to
    determine whether McKinney suffered from PTSD on the
    basis that the question was irrelevant to his sentencing
    determination, the Arizona Supreme Court incorrectly stated
    that the sentencing judge “assum[ed] the diagnoses were
    correct” when sentencing McKinney. McKinney, 
    917 P.2d at 1234
    . However, as set forth above, the record contradicts this
    statement. In fact, the sentencing judge specifically declined
    to make a finding on this point on the grounds that “even if
    46                  MCKINNEY V. RYAN
    the diagnoses of [PTSD] were accurate in Mr. McKinney’s
    case, [I do not believe that it] in any way significantly
    impaired Mr. McKinney’s conduct.” Sentencing Hr’g Tr. at
    28, July 23, 1993; see also id. at 30 (“[E]ven though there
    may be some evidence [demonstrating] a capacity by the
    defendant to appreciate the wrongfulness of conduct [sic], it
    was not significantly impaired [by] the possibility of a
    diagnosis of Post-traumatic Stress Syndrome.”(emphasis
    added)). Thus, the sentencing judge never accepted the
    diagnosis as correct. Instead, he did not believe it was
    necessary to determine whether McKinney suffered from
    PTSD because the absence of a causal relationship between
    the PTSD and McKinney’s crimes rendered this evidence
    nonmitigating as a matter of law. Given this, the Arizona
    Supreme Court’s decision was based on two “unreasonable
    determination[s] of the facts in light of the evidence presented
    in the State court proceeding.” § 2254(d)(2).
    While unconstitutional, the Arizona courts’ inconsistent
    treatment of McKinney’s childhood and PTSD mitigation
    evidence is explicable as consistent with then-operative
    Arizona state law. Section 13-751 of the Arizona Revised
    Statutes sets forth the factors which permissibly may be
    considered as mitigating under state law. 
    Ariz. Rev. Stat. § 13-751
    (G)(1). At the time, § 13-751(G)(1) permitted
    sentencers to give mitigating effect to mental impairments,
    such as PTSD, only when “[t]he defendant’s capacity to
    appreciate the wrongfulness of his conduct or to conform his
    conduct to the requirements of the law was significantly
    impaired but not so impaired as to constitute a defense to
    prosecution.” Given the language of this statute, it is not
    surprising that both Arizona courts’ decisions track that
    language when discussing McKinney’s PTSD evidence. Just
    compare the sentencing judge’s statement that “even if the
    MCKINNEY V. RYAN                       47
    diagnoses of Post-traumatic Stress Syndrome were accurate
    in Mr. McKinney’s case, [I do not believe] that in any way
    significantly impaired Mr. McKinney’s conduct,” and the
    Arizona Supreme Court’s statement that “none of the
    evidence showed . . . that such conditions in any way
    significantly impaired McKinney’s ability to conform his
    conduct to the law,” McKinney, 
    917 P.2d at 1234
    , with the
    language of § 13-751(G)(1). Further, as discussed above, the
    sentencing judge went so far as to make his reliance on § 13-
    751(G)(1) explicit, stating that McKinney’s PTSD evidence
    was irrelevant because “even though there may be some
    evidence . . . that would demonstrate under (G)(1) a capacity
    by the defendant to appreciate the wrongfulness of conduct,
    it was not significantly impaired [by] the possibility of a
    diagnosis of Post-traumatic Stress Syndrome.” Sentencing
    Hr’g Tr. at 30, July 23, 1993.
    It was not until 2006, over a decade after McKinney was
    sentenced, that the Arizona Supreme Court acknowledged
    that the United States Constitution required it to construe
    § 13-751(G)(1)’s nexus requirement as useful to only the
    determination of how much weight to give mitigating
    evidence—as opposed to excluding it from consideration.
    See Schad v. Ryan, 
    671 F.3d 708
    , 723 (9th Cir. 2011) (citing
    State v. Newell, 
    132 P.3d 833
    , 849 (Ariz. 2006)). However,
    prior to 2006, Arizona state courts routinely imposed an
    unconstitutional nexus requirement on mental impairments.
    See, e.g., Williams v. Ryan, 
    623 F.3d 1258
     (9th Cir. 2010)
    (finding a constitutional violation where Arizona courts
    refused to consider drug use as mitigating due to lack of a
    nexus); Styers v. Schriro, 
    547 F.3d 1026
    , 1035 (9th Cir. 2008)
    (per curiam) (finding a constitutional violation where Arizona
    courts refused to consider PTSD evidence as mitigating due
    to lack of a nexus). We can infer from the Arizona state
    48                  MCKINNEY V. RYAN
    courts’ pre-2006 treatment of mental impairment mitigation
    evidence in capital sentencings that the Arizona state courts
    here simply followed suit. However, regardless of the
    explanation for the Arizona Supreme Court’s various factual
    and legal errors, these constitutional violations establish that
    McKinney is entitled to habeas relief under AEDPA. See
    
    28 U.S.C. § 2254
    (d).
    IV.
    There is no question that McKinney’s PTSD evidence is
    “relevant mitigating evidence” for constitutional purposes.
    Eddings, 
    455 U.S. at 114
    ; see also Tennard v. Dretke,
    
    542 U.S. 274
    , 284 (2004) (“[T]he meaning of relevance is no
    different in the context of mitigating evidence introduced in
    a capital sentencing proceeding than in any other context, and
    thus the general evidentiary standard—any tendency to make
    the existence of any fact that is of consequence to the
    determination of the action more probable or less probable
    than it would be without the evidence—applies.” (internal
    quotation marks omitted)). The Supreme Court has
    confirmed that disorders like PTSD are relevant for
    mitigation purposes:
    [E]vidence about the defendant’s background
    and character is relevant because of the belief,
    long held by this society, that defendants who
    commit criminal acts that are attributable to a
    disadvantaged background, or to emotional
    and mental problems, may be less culpable
    than defendants who have no such excuse.
    MCKINNEY V. RYAN                        49
    Penry v. Lynaugh, 
    492 U.S. 302
    , 319 (1989) (internal
    citations and quotation marks omitted) abrogated on other
    grounds by Atkins v. Virginia, 
    536 U.S. 304
     (2002).
    We have also specifically held that PTSD evidence is
    relevant mitigation evidence. See Styers, 
    547 F.3d at 1035
    .
    In Styers, we granted a habeas petition when the Arizona
    courts refused to consider PTSD mitigation evidence under
    circumstances virtually identical to those presented here.
    Styers, convicted of murder, had produced evidence at
    sentencing that he suffered from PTSD. 
    Id.
     The Styers
    sentencing judge refused to consider the evidence on the basis
    that “two doctors who examined defendant could not connect
    defendant’s condition to his behavior at the time of the
    conspiracy and the murder.” 
    Id.
     (citing State v. Styers, 
    865 P.2d 765
     (Ariz. 1993)). As in the present appeal, the Arizona
    Supreme Court in Styers ignored this language, instead
    asserting, like here, that the sentencing judge had “considered
    all of the proffered mitigation.” 
    Id.
     (citing Styers, 
    865 P.2d at 778
    ). However, unlike the majority here, in Styers, we
    refused to accept this conclusory statement as dispositive. 
    Id.
    Instead, we recognized that the Arizona courts had failed to
    weigh Styers’s PTSD as evidence in mitigation on the basis
    that the experts did not connect the PTSD to his behavior at
    the time of the murder. 
    Id.
     We held that the Arizona court
    had applied an unconstitutional “nexus test to conclude that
    Styers’s post traumatic stress disorder did not qualify as
    mitigating evidence,” and granted Styers’s petition on the
    ground that this was “directly contrary to the constitutional
    requirement that all relevant mitigating evidence be
    considered by the sentencing body.” 
    Id.
    Here, as in Styers, the State of Arizona has sentenced an
    individual to death without complying with the constitutional
    50                  MCKINNEY V. RYAN
    requirement that the sentencer adequately consider “any
    relevant mitigating evidence.” Eddings, 
    455 U.S. at 114
    . In
    both cases, the Arizona courts refused to consider the
    mitigating impact of PTSD evidence because the defendant
    failed to establish a causal relationship between the disorder
    and his criminal conduct. However, unlike the majority here,
    in Styers we correctly recognized that this legal error was
    contrary to clearly established constitutional law, and granted
    habeas relief accordingly. I would grant McKinney relief on
    the Eddings/Lockett claim. It is abundantly clear on this
    record that McKinney is entitled to a new sentencing
    proceeding in which the sentencer actually considers his
    PTSD diagnosis as a mitigating factor as required by the
    Constitution.
    V.
    Whether McKinney must also demonstrate actual
    prejudice for the writ to issue is an unsettled question in the
    Ninth Circuit. Historically, we have treated Eddings errors as
    structural, granting the writ without inquiring as to the
    likelihood of a different sentencing result. See, e.g.,
    Williams, 
    623 F.3d 1258
    ; Styers, 
    547 F.3d 1026
    ; see also
    Stokley v. Ryan, 
    705 F.3d 401
    , 405 (9th Cir. 2012) (Paez, J.,
    dissenting). However, recently a panel of our Court refused
    to grant the writ despite assuming that an Eddings error had
    occurred at the state level. Stokley, 705 F.3d at 405. Instead,
    the panel examined whether the petitioner could demonstrate
    actual prejudice under Brecht v. Abrahamson, 
    507 U.S. 619
    (1993). Stokley, 705 F.3d at 403–05. Concluding that the
    petitioner could not do so, the panel refused to grant the writ.
    Id. Despite this, the Stokley panel majority stopped well short
    of overruling our precedent, which, in any event, it was
    without the power to do. See United States v. Parker,
    MCKINNEY V. RYAN                        51
    
    651 F.3d 1180
    , 1184 (9th Cir. 2011) (per curiam) (“Only the
    en banc court can overturn a prior panel precedent.”); see also
    Miller v. Gammie, 
    335 F.3d 889
    , 892–93 (9th Cir. 2003)
    (holding that a three-judge panel “may reexamine normally
    controlling circuit precedent” only “where the reasoning or
    theory of our prior circuit authority is clearly irreconcilable
    with the reasoning or theory of intervening higher authority”).
    As a result, Stokley has created an intra-circuit split
    concerning whether Eddings errors are structural or are
    reviewed for actual prejudice. Absent an en banc call to
    correct this issue, I would maintain the uniformity of our
    prior precedents by remaining faithful to the numerous cases
    that have treated Eddings/Lockett errors as structural, and not
    following the one outlier decision that failed to do so. See,
    e.g., Williams, 
    623 F.3d 1258
    .
    However, even assuming that Eddings/Lockett violations
    are reviewed for “actual prejudice,” I would conclude that the
    Eddings/Lockett error in this case had a “substantial and
    injurious effect or influence” upon the sentencer’s decision.
    Brecht, 
    507 U.S. at 627
    . The Brecht standard examines
    whether the constitutional error substantially influenced the
    outcome of a case:
    [I]f one cannot say, with fair assurance, after
    pondering all that happened without stripping
    the erroneous action from the whole, that the
    judgment was not substantially swayed by the
    error, it is impossible to conclude that
    substantial rights were not affected. The
    inquiry cannot be merely whether there was
    enough to support the result, apart from the
    phase affected by the error. It is rather, even
    52                  MCKINNEY V. RYAN
    so, whether the error itself had substantial
    influence.
    Merolillo v. Yates, 
    663 F.3d 444
    , 454 (9th Cir. 2011) (quoting
    Kotteakos v. United States, 
    328 U.S. 750
    , 765 (1946)).
    “Where the record is so evenly balanced that a judge ‘feels
    himself in virtual equipoise as to the harmlessness of the
    error’ and has ‘grave doubt about whether an error affected a
    jury [substantially and injuriously], the judge must treat the
    error as if it did so.’” 
    Id.
     (quoting O'Neal v. McAninch,
    
    513 U.S. 432
    , 435 (1995)) (alteration in original) (internal
    quotations omitted).
    McKinney has argued that he is entitled to a new
    sentencing proceeding because the sentencing judge’s failure
    to appropriately consider his PTSD diagnosis resulted in a
    death sentence when a life sentence was called for based on
    his lessened culpability. Here, McKinney’s sentence was
    “substantially swayed” by the sentencing judge’s error.
    Merolillo, 
    663 F.3d at 454
    . A sentencer who appropriately
    considered all the relevant mitigating evidence as required by
    Lockett could easily have concluded on the basis of Dr.
    McMahon’s testimony that McKinney’s PTSD was a
    substantial mitigating factor. Instead, the sentencing judge’s
    unconstitutional refusal to consider the effect of McKinney’s
    PTSD on his culpability for his crimes “creates the risk that
    the death penalty will be imposed in spite of factors which
    may call for a less severe penalty.” Lockett, 
    438 U.S. at 605
    .
    Given the significant non-PTSD mitigation evidence that
    McKinney presented at sentencing, it cannot be said “with
    fair assurance” that a sentencer who also appropriately
    considered the PTSD evidence would have sentenced
    McKinney to death. Merolillo, 
    663 F.3d at 454
    . I would
    therefore reverse the district court and remand with
    MCKINNEY V. RYAN                    53
    instructions to grant McKinney’s habeas petition, and to
    require that the state court hold a new sentencing hearing
    within ninety days.
