    SUMMARY*
    Criminal Law
    The panel affirmed the district court’s grant of habeas
    corpus relief to Jose Echavarria, who was convicted and
    sentenced to death for killing FBI Special Agent John Bailey.
    Echavarria claimed that there was a constitutionally
    intolerable risk of bias, based on the fact that several years
    earlier Agent Bailey had investigated for possible criminal
    prosecution Nevada District Judge Jack Lehman, who
    presided over Echavarria’s trial.
    The panel reviewed the Nevada Supreme Court’s decision
    de novo, rather than with AEDPA deference, because the
    Nevada Supreme Court adjudicated only Echavarria’s claim
    of actual bias, not his distinct claim of risk of bias.
    The panel held that Echavarria’s right to due process was
    violated because for an average judge in Judge Lehman’s
    position there would have been a constitutionally intolerable
    risk of bias.

    OPINION
    W. FLETCHER, Circuit Judge:
    In this capital case, the State of Nevada appeals from a
    grant of habeas corpus to Petitioner Jose Echavarria.
    Echavarria was convicted and sentenced to death for killing
    an agent of the Federal Bureau of Investigation (“FBI”).
    Several years earlier, that same FBI agent had investigated for
    possible criminal prosecution the judge who presided over
    Echavarria’s trial. Echavarria was never told of the
    connection between the FBI agent and the judge. The district
    court held that this unrevealed connection violated due
    process by creating a constitutionally intolerable risk of
    judicial bias. We agree.
    I. Factual Background
    According to the evidence presented at trial, Echavarria
    attempted to rob a Las Vegas bank on June 25, 1990. FBI
    Special Agent John Bailey was at the bank on unrelated FBI
    4                  ECHAVARRIA V. FILSON
    business. Echavarria tried to rob a teller at gunpoint. The
    teller screamed, and Echavarria abandoned the robbery
    attempt. As Echavarria walked toward the bank’s front door,
    Agent Bailey drew his gun, identified himself as an FBI
    agent, and ordered Echavarria to stop. Echavarria continued
    walking. Agent Bailey fired a shot that shattered the glass in
    the door. Echavarria stopped and, at Agent Bailey’s orders,
    dropped his gun. Agent Bailey frisked Echavarria and asked
    a bank employee to retrieve handcuffs from Agent Bailey’s
    car.
    Before Echavarria could be handcuffed, he knocked
    Agent Bailey to the ground. Echavarria retrieved his gun and
    shot Agent Bailey three times. Echavarria then ran out of the
    bank and got into a car in which his getaway driver, Carlos
    Gurry, was waiting. Gurry was apprehended by Las Vegas
    police that afternoon. Echavarria drove the getaway car to
    Juarez, Mexico, arriving there early the next morning.
    A. FBI Assistance to the Prosecution
    The FBI immediately launched an investigation. FBI
    Agent Alvaro Cruz testified at a suppression hearing in state
    court that he agreed that the case was of “great importance”
    to his office “because of the fact that it was a special agent of
    the FBI, who was a victim of this homicide.”
    On the morning of June 26, the FBI contacted Jose
    Rubalcava, Commandante of the Chihuahua State Judicial
    Police in Juarez, Mexico, to ask for his assistance in locating
    and arresting Echavarria. Commandante Rubalcava, who had
    a long-standing cooperative arrangement with the FBI,
    assigned twenty-eight agents to the task. Mexican authorities
    arrested Echavarria that night at about 8:30 pm at the Juarez
    ECHAVARRIA V. FILSON                      5
    airport and took him to the Juarez police station. After
    learning of Echavarria’s arrest, four agents from the FBI’s El
    Paso office, including Agent Cruz, drove across the border,
    arriving at the Juarez police station at about 11:00 pm.
    Echavarria signed a confession the next morning. Before
    trial, he moved for suppression of his confession, alleging
    that it was obtained by torture.
    Oren Gordon, a former employee of the Drug
    Enforcement Administration with experience working along
    the U.S.-Mexico border, testified at the hearing on
    Echavarria’s suppression motion:
    Q: And what was the general reputation of
    law enforcement agents in Mexico, for the
    use of physical abuse and torture, to
    obtain statements from suspects and
    witnesses?
    A: It was a common occurrence. It was a
    regular technique used to entice the person
    or induce the person to say what they
    wanted him to say . . . .
    Gordon testified further that Mexican authorities used
    electrical devices to administer shocks during interrogations.
    He testified that devices with transformers, characterized by
    a humming sound when turned on, generally did not leave
    marks.
    Agent Manuel Marquez, one of the four FBI agents who
    drove to Juarez, denied knowing this general reputation.
    When asked whether Mexican law enforcement authorities
    6                  ECHAVARRIA V. FILSON
    have a “reputation among law enforcement agents, with
    whom you interface, as obtaining statements through torture
    or physical abuse,” he responded, “Within the law
    enforcement community, no.” When asked about the
    reputation “within the community in Juarez and El Paso,”
    Agent Marquez responded, “Yes.”
    Echavarria testified at the suppression hearing that he was
    tortured by the Mexican police. According to Echavarria,
    police officers hit him while he was in the car on the way
    from the airport to the police station. When they arrived at
    the station, he was taken to the “Commandante,” who advised
    him to cooperate, or else Maria, Echavarria’s former
    girlfriend who had helped him when he arrived in Juarez,
    “would be paying the consequences.” When Echavarria
    refused to cooperate, he was taken to the second floor of the
    police station, where his clothes were taken off. He was told
    to spread his legs. The Mexican police beat him in the face,
    using an open hand to avoid leaving marks, and between the
    legs. After about an hour or an hour and a half, Echavarria
    was clothed and taken back down to the first floor. He was
    put in a room with the Commandante and two FBI agents,
    one of whom spoke Spanish. The agents “asked me then if I
    was ready to make a confession.” When Echavarria refused,
    the Commandante “told his agent to take [Echavarria]
    upstairs to the second floor again.”
    Once back on the second floor, Echavarria was again
    stripped. This time, he was blindfolded. He was again beaten
    in the face and between the legs. He heard someone cock a
    gun next to his ear, and then felt the gun pressed against his
    head. Echavarria was told he would be shot and thrown in
    the river. Next, he heard what sounded like a welding
    machine being turned on, and the officers shocked
    ECHAVARRIA V. FILSON                       7
    Echavarria’s “private parts.” They kept asking “[i]f I was
    ready to make a confession.”
    Echavarria was then taken down to the first floor, where
    “there was a tall white hair man who was a FBI of the United
    States . . . [who] would ask me again whether I was going to
    cooperate with them.” Echavarria was also taken to the
    basement, where his former girlfriend Maria and her sister
    were being held. Police officers threatened to beat Maria and
    “tighten her nipples, the breast nipples,” and do other
    “obscene things” to her.
    Having been brought “up to the second floor twice and
    . . . once down to the cell downstairs,” Echavarria signed a
    confession. He testified that he did so because “I had no
    alternative.”
    The prosecution called as witnesses at the suppression
    hearing two of the four FBI agents who had driven together
    to Juarez. Agent Cruz testified that he and the other agents
    met with Commandante Rubalcava and several other
    Mexican police officers, and that Echavarria was brought into
    the room. Agent Cruz testified that they interviewed
    Echavarria for about thirty minutes. He also testified that
    none of the four FBI agents who went to Juarez had white
    hair. Agent Marquez estimated that the interview took thirty
    to forty minutes. He testified that he gave Miranda warnings
    to Echavarria orally, but that Echavarria did not sign the usual
    FBI form acknowledging the warnings because the FBI
    agents did not have the form with them.
    Agents Cruz and Marquez both testified that they saw no
    marks on Echavarria or other indications of physical abuse,
    and that they never saw Echavarria again that night. Agent
    8                  ECHAVARRIA V. FILSON
    Cruz testified, “I believe that we just went back to our car and
    came back to El Paso.”
    Echavarria’s confession, signed at about 11:00 am the
    next morning, stated:
    He then walked and entered the bank and
    went towards the tellers booths of the bank, he
    approached one of them which was being
    tended by a woman whom he knows was
    named CANY VELAZQUEZ and once in
    front of her, the declarant took the pistol and
    showed it to the teller already mentioned
    telling her in English “I have a gun in the
    hand, give me the money” . . . .
    [T]he FBI agent approached him with his
    pistol on the hand ordering the declarant to
    leave his weapon on the floor of the bank and
    declarant put his pistol on the floor so that
    afterwards, the FBI agent proceeded to put his
    pistol in the holster.
    He ordered the declarant to sit on a chair
    and declarant complied and when the FBI
    agent proceeded to handcuff both his hands,
    declarant threw himself against the FBI agent
    managing to throw him down on the floor and
    declarant managed to set himself loose and
    then grabbed his Rohm .38 special caliber
    pistol that was on the floor. With this, he shot
    three rounds at the FBI agent named JOHN
    BAILEY from a distance of one and a half
    meters while he was still lying on the floor.
    ECHAVARRIA V. FILSON                    9
    Echavarria did not independently know the names of the FBI
    agent he had shot or of the bank teller he had attempted to
    rob. This information was supplied by the FBI.
    Echavarria was formally turned over to the FBI at the
    U.S.-Mexico border later in the day on June 27. He was
    processed at the FBI’s office in El Paso. FBI agents then
    accompanied Echavarria on a flight from El Paso to Las
    Vegas. They were met at the airport by the Las Vegas
    Metropolitan Police, who took custody of Echavarria and
    booked him. FBI agents remained with Echavarria through
    the booking process.
    Ten days after he was captured in Juarez, Echavarria was
    charged in Nevada with capital murder.
    The FBI was deeply involved in developing witness
    testimony. FBI agents interviewed about a dozen witnesses,
    including the bank teller whom Echavarria had attempted to
    rob. An FBI agent was present when the teller was shown a
    photographic lineup.      FBI agents interviewed Maria,
    Echavarria’s former girlfriend. They also interviewed
    Maria’s brother, who had disposed of two guns for Echavarria
    and had driven him to the Juarez airport.
    The FBI also actively developed physical evidence. FBI
    agents executed a search warrant on the car that Gurry had
    driven as the getaway vehicle from the bank and that
    Echavarria had driven from Las Vegas to Juarez. Glass
    fragments and fingerprints recovered from the car were sent
    to the FBI laboratory in Washington, D.C., for analysis. An
    FBI fingerprint specialist matched Echavarria’s prints to
    those found in the car. An FBI forensic geologist examined
    the glass fragments and matched them to glass from the
    10                 ECHAVARRIA V. FILSON
    shattered door of the bank. An FBI ballistics expert analyzed
    a recovered .38 caliber revolver and matched it to bullets
    removed from Agent Bailey’s body. An FBI language
    specialist translated Echavarria’s confession from Spanish to
    English. FBI agents took the bank’s camera film to have it
    developed at a lab. About half a dozen FBI agents were
    involved in the development of the film. FBI agents
    contacted officials at the First Interstate Bank of Nevada,
    where Gurry had an account. The agents were led to the bank
    by a deposit slip an FBI agent had found in Echavarria’s
    wallet.
    B. FBI Investigation of the Nevada Trial Judge
    Echavarria’s case was assigned to Nevada District Judge
    Jack Lehman. Judge Lehman had been investigated several
    years earlier by Agent Bailey for corruption, fraud, and
    perjury. FBI documents describing the investigation were
    sealed by the federal district court. After soliciting the views
    of the parties and of the United States, we unsealed the
    documents in this court. The narrative that follows is based
    in part on the contents of the previously sealed documents.
    According to the FBI documents, Agent Bailey received
    information in 1985 “that the state of Nevada was losing
    millions of dollars on low cost housing land being sold . . . by
    the Colorado River Commission (CRC).” The CRC was
    allegedly selling state-owned land for a fraction of its actual
    value, allowing the buyers to resell at substantial profits.
    Lehman was the Chairman of the CRC during the relevant
    time.
    Agent Bailey opened a formal FBI investigation in 1986.
    Agent Bailey learned during the course of his investigation
    ECHAVARRIA V. FILSON                    11
    that the CRC had sold a 120-acre parcel of land in Laughlin,
    Nevada, (the “Laughlin property”) to developer John H.
    Midby in late 1983 or early 1984. Midby had bought the
    Laughlin property from the CRC for $2,500 per acre. At
    about the same time, another developer had paid $45,000 per
    acre for land immediately adjacent to the Laughlin property.
    The CRC had five commissioners. Lehman and Robert
    Bugbee were the two CRC commissioners who had supported
    Midby’s bid for the Laughlin property from the beginning
    and whose view eventually prevailed in the CRC.
    From 1980 to 1982, before making a bid on the Laughlin
    property, Midby had negotiated with the American Bank of
    Commerce for a lease of 5,000 square feet of commercial
    space that Midby owned and into which the bank wished to
    expand. Lehman and Bugbee were members of the bank’s
    Board of Directors. Bugbee volunteered to lead the bank’s
    lease negotiations with Midby. After being at a “standstill”
    over Midby’s asking price of $1.05 to $1.15 per square foot,
    plus $165,000 in improvements to be paid for by the bank,
    Midby agreed to drop the price to $0.85 per square foot, plus
    only $80,000 to $90,000 to be paid for the improvements.
    Midby also provided an additional 1,000 square feet of space
    that would be rent-free for a year. The other board members
    at the bank were “pleasantly surprised at [Bugbee’s] ability
    to negotiate with [Midby].” One of the bank’s co-founders
    later “realized that something may very well have been amiss
    . . . .”
    The FBI file compiled by Agent Bailey contained
    evidence that Lehman may have committed perjury in 1986
    while testifying before the Nevada Gaming Control Board
    about the Midby lease. Lehman had testified under oath
    before the Board that he had “‘[a]bsolutely nothing’ to do
    12                ECHAVARRIA V. FILSON
    with negotiating the lease” between Midby and the bank.
    However, the FBI file contained three letters signed by
    Lehman—one in December 1980 and two in January
    1981—in which Lehman discussed and negotiated terms of
    the Midby lease.
    On August 31, 1987, after reviewing the FBI’s file, the
    U.S. Attorney’s Office for the District of Nevada declined to
    prosecute Lehman either for federal Hobbs Act violations or
    for perjury. It deemed the perjury charge to be “a matter for
    state prosecution.” The next day, James Weller, the FBI
    Special Agent in Charge, wrote to William Maddox, the U.S.
    Attorney, concerning the documents showing that Lehman
    may have committed perjury. He wrote, “This office feels
    strongly that State officials should have access to these
    documents inasmuch as the alleged perjury took place before
    the Nevada Gaming Control Board.” He wrote further, “This
    office intends to turn [the documents] over to the chairman of
    the Gaming Control Board who has expressed an intense
    interest in any information indicating a witness may have lied
    before the Gaming Control Board.” Weller indicated that he
    would not make “[s]uch disclosure . . . until such time as you
    concur with this proposal and until such time as, pursuant to
    [Fed. R. of Crim. Proc.] 6(e), a United States District Court
    Judge so orders.” In a handwritten internal FBI memorandum
    to the Special Agent in Charge, dated December 5, 1987,
    Agent Bailey wrote, “Following discussion with AUSA
    Meyer, it is recommended this matter be maintained as –
    Pending – until such time as the USA’s office receives
    authority from D of J to present to a USDC Judge in Las
    Vegas to present state officials with evidence of perjury
    committed in state court with respect to Lehman and
    [redacted].”
    ECHAVARRIA V. FILSON                   13
    On June 23, 1988, federal District Judge Lloyd George
    authorized the release of the documents to the Gaming
    Control Board and the Nevada Attorney General’s Office. So
    far as the record reveals, no state charges were ever filed
    against Lehman. On October 5, 1990, Ronald Asher of the
    Gaming Control Board advised the FBI that “a review of their
    files failed to disclose any reference to Jack Lehman.”
    C. Failure to Recuse
    On September 17, 1990, before Echavarria’s trial began,
    Judge Lehman held a conference call with the lead
    prosecutor, Chief Deputy District Attorney William Henry,
    and Gurry’s counsel, David Wall. Wall stated in a sworn
    declaration:
    During my representation of Mr. Gurry, I
    learned that the FBI had conducted an
    investigation of the Colorado River
    Commission at a time when Judge Lehman
    was a member of the Commission. Prior to
    trial, I participated in a telephone conference
    call with Judge Lehman and one of the
    prosecutors, either Mr. Henry or Mr. Harmon.
    ...
    Judge Lehman indicated during the
    conference call that a reporter had asked him
    whether he would recuse himself in the trial of
    Mr. Gurry and Mr. Echavarria due to Judge
    Lehman having been a member of the
    Colorado River Commission at the time it was
    investigated by the FBI. Judge Lehman asked
    14                ECHAVARRIA V. FILSON
    if either party wanted to move to have the
    judge recuse himself.
    Neither I nor the prosecution asked that
    Judge Lehman recuse himself.
    In an internal memorandum, Wall also noted that Judge
    Lehman said that “his wife had been approached on 9/17/90
    and told that Judge Lehman ought not to be presiding over the
    case since it was Agent Bailey who had investigated actions
    of Lehman on the Colorado River Commission prior to
    Lehman’s appointment as a District Judge.” According to the
    memorandum, “[B]oth Bill Henry and [Wall] indicated that
    they did not believe that it was in any way harmful or
    prejudicial.” It appears from Wall’s declaration and
    memorandum that Judge Lehman did not fully explain to him
    the nature and extent of the FBI’s investigation.
    On October 9, 1990, FBI agents met with Clark County
    District Attorney Rex Bell and Chief Deputy DA Henry.
    According to an FBI memorandum describing the meeting,
    the agents provided information about the FBI’s investigation
    of Judge Lehman. The memorandum noted that “[t]he
    purpose of providing this information was to advise the DA
    and the prosecuting ADA of its existence [so] that they could
    evaluate its impact for use by the defense counsel in court
    and/or appeal motions based on due process and equal
    protection considerations and claiming judicial bias.” The
    memorandum went on:
    ADA HENRY advised that defense counsel
    for CARLOS GURRY was aware of Judge
    LEHMAN’s involvement with SA BAILEY
    on official business but he did not believe that
    ECHAVARRIA V. FILSON                     15
    counsel for JOSE ECHAVARRIA had that
    information. ADA HENRY said that he would
    suggest a chambers meeting to discuss this
    with all counsel present at the next court
    appearance.
    (Emphasis added.)
    On October 17, the FBI wrote a follow-up memorandum
    summarizing the information it had compiled about Judge
    Lehman. In addition to information about the CRC, the bank,
    and Lehman’s testimony before the Gaming Control Board,
    the memorandum described an allegedly fraudulent land sale
    to a group that included Lehman: The buying group did not
    participate in the fraud, but it allegedly “did not inform
    anyone of the fraud” and stood to “collect on title insurance
    as an innocent buyer once the fraud was divulged.” The
    memorandum also described a complaint alleging that
    Lehman, acting for the CRC, extended a time limit for an
    airport project “so that another firm with whom Lehman had
    an interest could obtain the contract.”
    No “chambers meeting to discuss this with all counsel
    present,” as contemplated in the memorandum describing the
    meeting between the FBI and the state prosecutors, ever took
    place. It is undisputed that Echavarria and his defense
    attorneys did not learn about the FBI’s investigation of Judge
    Lehman until well after trial and sentencing.
    II. Procedural History
    Echavarria and Gurry were indicted on five
    counts—murder with use of a deadly weapon, conspiracy to
    commit robbery, burglary with intent to commit robbery,
    16                 ECHAVARRIA V. FILSON
    attempted robbery with use of a deadly weapon, and escape
    with a dangerous weapon. They were tried together. After
    the hearing described above, Judge Lehman denied
    Echavarria’s motion to suppress his confession. Echavarria
    was convicted on all five counts and was sentenced to death.
    Gurry was convicted on all counts except escape and was
    sentenced to life with the possibility of parole.
    Before entry of judgment, Echavarria moved for a new
    trial based on, inter alia, juror misconduct. Judge Lehman
    threatened to file a bar complaint against Echavarria’s
    counsel for interviewing jury members in connection with the
    motion. Judge Lehman then recused himself from hearing the
    motion. After a different judge denied the motion, Judge
    Lehman entered judgment sentencing Echavarria to death.
    Echavarria appealed his conviction and sentence to the
    Nevada Supreme Court. He asserted a claim of actual
    judicial bias based on Judge Lehman’s hostility to his counsel
    during trial. Echavarria argued that he was “deprive[d] . . . of
    a fundamentally fair trial” by “comments of the Court [that]
    went far beyond legal admonishments on points of law and
    took the form of enraged rebukes to counsel.” Echavarria did
    not yet know of any connection between Judge Lehman and
    Agent Bailey.
    The Nevada Supreme Court affirmed Echavarria’s
    conviction and sentence. The Court did not specifically
    address Echavarria’s actual judicial bias claim. After
    addressing a number of other claims in detail, it wrote at the
    end of its opinion, “We have carefully examined appellants’
    numerous other assignments of error and determine that they
    lack merit.” The United States Supreme Court denied
    certiorari.
    ECHAVARRIA V. FILSON                        17
    Echavarria’s first state habeas petition was denied by
    Judge Lehman. The Nevada Supreme Court dismissed
    Echavarria’s appeal and denied rehearing. Echavarria then
    filed a federal habeas petition pro se. After counsel was
    appointed and filed an amended petition, the federal district
    court allowed Echavarria to subpoena the FBI to obtain
    information about Agent Bailey’s investigation. The district
    court then stayed Echavarria’s federal habeas proceedings to
    allow him to present to the state court the evidence he
    discovered about the investigation.
    Based on “the law of the case doctrine,” the state district
    court denied Echavarria’s second state habeas petition, in
    which he claimed “judicial bias” and “tortured confession.”
    Echavarria then filed a third state habeas petition, which was
    also denied. Echavarria appealed the denial of both petitions
    to the Nevada Supreme Court. In his appeal, Echavarria
    distinguished his claim that “Judge Lehman’s conduct
    evidences an actual bias” from a separate claim that
    Echavarria called “compensatory bias.” In support of his
    “compensatory bias” claim, Echavarria cited a Fifth Circuit
    case that explained that “[p]resumptive bias occurs when a
    judge may not actually be biased, but has the appearance of
    bias such that the probability of actual bias . . . is too high to
    be constitutionally tolerable.”          See Richardson v.
    Quarterman, 
    537 F.3d 466
    , 475 (5th Cir. 2008) (internal
    quotation marks and citation omitted). He also cited a
    Seventh Circuit case that explained that due process “may
    sometimes bar trial by judges who have no actual bias and
    who would do their very best to weigh the scales of justice
    equally between contending parties. . . . [T]o perform its high
    function in the best way justice must satisfy the appearance
    of justice.” See Bracy v. Schomig, 
    286 F.3d 406
    , 410–11 (7th
    Cir. 2002) (quoting Offut v. United States, 
    348 U.S. 11
    , 14
    18                 ECHAVARRIA V. FILSON
    (1954)) (internal quotation marks omitted). Echavarria
    argued, “Judge Lehman’s in court rulings in Mr. Echavarria’s
    case can best be explained by a desire to appear as a law and
    order judge to Agent Bailey’s employer.” Echavarria’s two
    trial counsel filed declarations stating that they would have
    moved to disqualify Judge Lehman if they had known about
    the investigation.
    The Nevada Supreme Court denied Echavarria’s appeal
    of the denial of his second and third state habeas petitions.
    The Court wrote, “Although it appears that Echavarria did not
    learn of Agent Bailey’s investigation until well after trial, the
    incidents he identifies as evidence of judicial bias were
    largely raised on direct appeal and rejected summarily by this
    court.” The Court characterized the information about Agent
    Bailey’s investigation of Judge Lehman as “[n]ew
    information as to the source of the alleged bias.” The court
    concluded that the new evidence was “not so significant as to
    persuade us to abandon the doctrine of the law of the case.”
    The United States Supreme Court denied certiorari.
    Echavarria returned to federal district court and filed a
    second amended habeas petition. In a written order, the
    district court denied claims based on allegedly invalid
    aggravating factors (Claim 2), allegedly improper jury
    instructions (Claims 7 and 12), an allegedly improper denial
    of an opportunity to investigate allegations of juror
    misconduct (Claim 9), alleged prosecutorial misconduct
    (Claim 11), and alleged cumulative error (Claim 15).
    The federal district court granted relief based on
    Echavarria’s claim of judicial bias (Claim 4). The court held
    that the Nevada Supreme Court had adjudicated Echavarria’s
    claim of actual judicial bias on the merits, and had not
    ECHAVARRIA V. FILSON                       19
    unreasonably applied United States Supreme Court case law
    in holding that Echavarria had not shown actual bias.
    However, the district court held that the Nevada Supreme
    Court had not adjudicated on the merits Echavarria’s claim
    that there was an intolerable risk of judicial bias that “might
    lead” the “average man as a judge” to be biased. See Tumey
    v. Ohio, 
    273 U.S. 510
    , 532 (1927). The district court wrote:
    The Nevada Supreme Court did not consider
    whether there was unconstitutional implied
    judicial bias.    Specifically, the Nevada
    Supreme Court did not consider whether the
    relationship between the trial judge, the FBI
    and the murdered FBI agent, and the FBI’s
    involvement in the case would give rise to a
    possible temptation to the average judge to
    not hold the balance nice, clear and true.
    Ruling de novo on what it called Echavarria’s “implied
    judicial bias” claim, the district court held that Echavarria had
    established a violation of his right to due process. The court
    wrote:
    Four years before Echavarria’s trial, the
    murder victim, FBI Agent Bailey, had
    conducted an investigation of serious fraud
    allegations concerning the trial judge. The
    trial judge was aware of that FBI
    investigation, as was the prosecution (and
    even counsel for Echavarria’s co-defendant),
    but Echavarria was not informed of it. The
    FBI played an important part in investigating
    Agent Bailey’s murder and in apprehending
    Echavarria. There was an issue in the case
    20              ECHAVARRIA V. FILSON
    regarding the treatment of Echavarria in
    Juarez, after his arrest was made through
    cooperation between the FBI and the police in
    Juarez. Several FBI agents testified, both at
    the evidentiary hearing regarding the
    admissibility of the statement given by
    Echavarria after his arrest in Juarez, and at
    trial. Under these circumstances, this Court
    concludes that there was a significant risk that
    an average judge would possibly be tempted
    to lean in favor of the prosecution or to
    potentially have an interest in the outcome of
    the case. For example, an average judge in
    this judge’s position might be tempted to
    d emo nstrate a lack of bias by
    overcompensating and ruling in a manner to
    avoid any suggestion that the judge harbored
    ill will against the FBI, or against the FBI
    agent murder victim, for having conducted the
    investigation.       Or, to give another
    example—keeping in mind that the inquiry is
    to be made “under a realistic appraisal of
    psychological tendencies and human
    weakness,” [Caperton v. A.T. Massey Coal
    Co., 
    556 U.S. 868
    , 883–84 (2009)]—an
    average judge in this judge’s position might
    be tempted to avoid rulings unfavorable to the
    FBI, or to the prosecution of the FBI agent’s
    alleged murderer, in order to appease the FBI
    and avoid any further investigation. Either of
    these inclinations would have tended to lend
    bias and tip the scales against Echavarria.
    ECHAVARRIA V. FILSON                    21
    In this Court’s view, it is an inescapable
    conclusion that the risk of bias on the part of
    the trial judge in this case was too high to
    allow confidence that the case was
    adjudicated fairly, by a neutral and detached
    arbiter, consistent with the Due Process
    Clause of the Federal Constitution.
    (Internal citations omitted.)
    The district court examined, but did not decide,
    Echavarria’s claim that his confession had been obtained by
    torture and was therefore improperly admitted (Claim 3). The
    district court analyzed Claim 3 in detail, suggesting that it
    would have credited Echavarria’s testimony that his
    confession had been obtained by torture, but the court
    “refrain[ed]” from deciding “whether Echavarria’s Juarez
    confession was voluntarily given.” The court wrote that it
    took this approach
    out of sensitivity to the interests of comity and
    federalism, and also considering the interest
    of judicial economy. . . . [T]his Court expects
    that the issue of the admissibility of
    Echavarria’s Juarez confession may be
    revisited in state court, before Echavarria’s
    retrial, in light of this Court’s ruling that the
    trial judge, who previously ruled upon the
    admissibility of the Juarez confession, had an
    unconstitutional implied bias. Under these
    circumstances, the Court will abstain from
    ruling on Claim 3, and will, instead, deny the
    claim, without prejudice, as moot.
    22                  ECHAVARRIA V. FILSON
    The district court granted habeas based on its ruling that
    Echavarria had shown that there was a constitutionally
    intolerable risk of judicial bias. It ordered that Nevada
    release or retry Echavarria, but stayed its judgment pending
    appeal. This appeal followed.
    III. Standard of Review
    We review the district court’s decision to grant the
    petition for habeas corpus de novo. Crittenden v. Chappell,
    
    804 F.3d 998
    , 1006 (9th Cir. 2015). We review the district
    court’s factual findings for clear error.

    IV. Discussion
    “A fair trial in a fair tribunal is a basic requirement of due
    process.” In re Murchison, 
    349 U.S. 133
    , 136 (1955).
    “Fairness of course requires an absence of actual bias in the
    trial of cases. But our system of law has always endeavored
    to prevent even the probability of unfairness.” 
    Id.
     (emphasis
    added).
    “[T]he Due Process Clause has been implemented by
    objective standards that do not require proof of actual bias.
    In defining these standards the Court has asked whether,
    ‘under a realistic appraisal of psychological tendencies and
    human weakness,’ the interest ‘poses such a risk of actual
    bias or prejudgment that the practice must be forbidden if the
    guarantee of due process is to be adequately implemented.’”
    Caperton v. A.T. Massey Coal Co., 
    556 U.S. 868
    , 883–84
    (2009) (quoting Withrow v. Larkin, 
    421 U.S. 35
    , 47 (1975))
    (internal citations omitted). The test does not require a
    showing of actual judicial bias, “though actual bias, if
    disclosed, no doubt would be grounds for appropriate relief.”
    ECHAVARRIA V. FILSON                     23
    Id. at 883. Rather, the test requires only a showing of an
    undue risk of bias, based on the psychological temptations
    affecting an “average judge.” Id. at 881. For example, in
    concluding that there had been an undue risk of bias, the
    Supreme Court wrote:
    We conclude that Justice Embry’s
    participation in this case violated appellant’s
    due process rights . . . . We make clear that we
    are not required to decide whether in fact
    Justice Embry was influenced, but only
    whether sitting on the case then before the
    Supreme Court of Alabama “would offer a
    possible temptation to the average . . . judge to
    . . . lead him not to hold the balance nice,
    clear and true.” The Due Process Clause
    “may sometimes bar trial by judges who have
    no actual bias and who would do their very
    best to weigh the scales of justice equally
    between the contending parties. But to
    perform its high function in the best way,
    ‘justice must satisfy the appearance of
    justice.’”
    Aetna Life Ins. Co. v. Lavoie, 
    475 U.S. 813
    , 825 (1986) (first
    elision added) (internal citations omitted). “The Constitution
    requires recusal where ‘the probability of actual bias on the
    part of the judge or decisionmaker is too high to be
    constitutionally tolerable.’” Hurles v. Ryan, 
    752 F.3d 768
    ,
    788 (9th Cir. 2014) (quoting Withrow, 
    421 U.S. at 47
    ).
    Echavarria claims that there was a constitutionally
    intolerable risk of bias, based on FBI Agent Bailey’s criminal
    investigation of Judge Lehman.
    24                ECHAVARRIA V. FILSON
    The Antiterrorism and Effective Death Penalty Act
    (“AEDPA”) requires us to give significant deference to the
    state court’s last reasoned decision—here, the Nevada
    Supreme Court’s decision on appeal from the denial of
    Echavarria’s second and third state habeas petitions. See
    
    28 U.S.C. § 2254
    (d). AEDPA deference applies to claims
    that were “adjudicated on the merits in State court
    proceedings.” Id.; see Lambert v. Blodgett, 
    393 F.3d 943
    ,
    966 (9th Cir. 2004). An adjudication on the merits is a
    “decision finally resolving the parties’ claims . . . that is
    based on the substance of the claim advanced, rather than on
    a procedural, or other, ground.” Lambert, 
    393 F.3d at 969
    (quoting Sellan v. Kuhlman, 
    261 F.3d 303
    , 311 (2d Cir.
    2001)). “Any federally reviewable claim that was not
    adjudicated on the merits in state court is reviewed de novo.”
    Runningeagle v. Ryan, 
    825 F.3d 970
    , 978 (9th Cir. 2016). If
    a state court denies a federal claim without giving any
    explanation, we presume that the decision was an
    adjudication on the merits. See Amado v. Gonzalez, 
    758 F.3d 1119
    , 1131 (9th Cir. 2014). But if a state court gives an
    “explicit explanation of its own decision,” we take the state
    court at its word. James v. Ryan, 
    733 F.3d 911
    , 916 (9th Cir.
    2013). “[W]hen it is clear that a state court has not reached
    the merits of a properly raised issue, we must review it de
    novo.” Pirtle v. Morgan, 
    313 F.3d 1160
    , 1167 (9th Cir. 2002)
    (footnote omitted).
    Here, the Nevada Supreme Court’s explanation of its
    decision on state habeas shows that it adjudicated only
    Echavarria’s claim of actual bias. It did not adjudicate his
    distinct claim of risk of bias. When the Nevada Supreme
    Court was presented with Echavarria’s claim of actual bias on
    direct appeal, there was no evidence in the record of Agent
    Bailey’s criminal investigation of Judge Lehman. Later,
    ECHAVARRIA V. FILSON                     25
    when presented in state habeas proceedings with evidence of
    Agent Bailey’s investigation, the Nevada Supreme Court
    wrote:
    Echavarria raised a claim of judicial bias on
    direct appeal, arguing that the trial judge
    made numerous disparaging and embarrassing
    comments about counsel. Although it appears
    that Echavarria did not learn of Agent
    Bailey’s investigation until well after trial, the
    incidents he identifies as evidence of judicial
    bias were largely raised on direct appeal and
    rejected summarily by this court. In his post-
    conviction petition, Echavarria merely refined
    this claim, contending that the genesis of the
    trial judge’s bias was related to Agent
    Bailey’s investigation of him.              New
    information as to the source of the alleged
    bias is not so significant as to persuade us to
    abandon the doctrine of the law of the case.
    (Internal citations omitted.)
    By invoking the “law of the case” as the basis for its
    denial of state habeas, the Nevada Supreme Court made clear
    that it treated its prior decision as “decid[ing] the issue” of
    bias “explicitly or by necessary implication.” Dictor v.
    Creative Mgmt. Servs., LLC, 
    223 P.3d 332
    , 334 (Nev. 2010).
    But on direct appeal, the Nevada Supreme Court had
    addressed only a claim of actual bias based on Judge
    Lehman’s hostility in court towards Echavarria’s counsel.
    The Nevada Supreme Court could not have addressed
    Echavarria’s distinct and later-raised claim of risk of bias,
    based on Agent Bailey’s investigation, because Echavarria
    26                 ECHAVARRIA V. FILSON
    had made no such claim on direct appeal. Indeed, at the time
    of his direct appeal, Echavarria had no knowledge of the
    investigation.
    The Nevada Supreme Court’s reasoning in denying
    Echavarria’s second and third habeas petitions makes clear
    that it decided only “whether the judge [was] actually,
    subjectively biased.” Caperton, 
    556 U.S. at 881
    . Reviewing
    the denial of state habeas, the Nevada Supreme Court
    described the evidence of Agent Bailey’s investigation as
    “[n]ew information as to the source of the alleged bias.” The
    Court deemed the new information insufficient because it did
    not convince the Court that Judge Lehman was actually
    biased. But actual bias was not the issue in Echavarria’s risk-
    of-bias claim. A showing of a constitutionally intolerable
    risk of bias does not require proof of actual bias. 
    Id. at 883
    ;
    see also Williams v. Pennsylvania, 
    136 S. Ct. 1899
    , 1905
    (2016) (“[T]he Court’s precedents apply an objective
    standard that, in the usual case, avoids having to determine
    whether actual bias is present.”). Indeed, due process “may
    sometimes require recusal of judges who have no actual bias
    and who would do their very best to weigh the scales of
    justice equally.” Hurles, 752 F.3d at 789 (internal quotation
    marks and citation omitted).
    The Nevada Supreme Court has made a similar error
    before. In Rippo v. Baker, 
    137 S. Ct. 905
     (2017) (per
    curiam), the Supreme Court “vacate[d] the Nevada Supreme
    Court’s judgment because it applied the wrong legal
    standard” for a post-conviction claim of judicial bias. 
    Id. at 907
    . The petitioner alleged that his trial judge was biased
    because the judge was the subject of an investigation
    involving the local district attorney’s office and Las Vegas
    police department. Rippo v. State, 
    368 P.3d 729
    , 743 (Nev.
    ECHAVARRIA V. FILSON                      27
    2016) (per curiam), vacated, Rippo v. Baker, 
    137 S. Ct. 905
    (2017) (per curiam). The Nevada Supreme Court had
    concluded, “Taking Rippo’s allegations as true, there
    remains [n]o factual basis . . . for Rippo’s argument that [the
    trial judge] was under pressure to accommodate the State or
    treat criminal defendants in state proceedings less favorably
    or that he was biased against Rippo because of the
    investigation and indictment.” Id. at 744 (internal quotation
    marks omitted) (alterations in original). The United States
    Supreme Court explained that “[t]he Nevada Supreme Court
    did not ask the question our precedents require: whether,
    considering all the circumstances alleged, the risk of bias was
    too high to be constitutionally tolerable.” Rippo, 
    137 S. Ct. at 907
    .
    Here, rather than applying the wrong legal standard to a
    risk-of-bias claim, the Nevada Supreme Court never decided
    the claim. The district court was therefore correct to review
    the claim de novo. We, too, review it de novo. We must
    determine “whether the average judge in [Judge Lehman’s]
    position is ‘likely’ to be neutral, or whether there is an
    unconstitutional ‘potential for bias.’” Caperton, 
    556 U.S. at 881
    . The rule is “stringent.” Hurles, 752 F.3d at 789
    (quoting Murchison, 359 U.S. at 136). It reaches “[e]very
    procedure which would offer a possible temptation to the
    average . . . judge to forget the burden of proof . . . or which
    might lead him not to hold the balance nice, clear and true
    between the State and the accused.” Id. (quoting Tumey,
    
    273 U.S. at 532
    ). It also requires “a realistic appraisal of
    psychological tendencies and human weakness.” 
    Id.
     (quoting
    Caperton, 
    556 U.S. at
    883–84).
    Judge Lehman was well aware of the FBI’s efforts to
    ensure Echavarria’s conviction. The average judge in his
    28                 ECHAVARRIA V. FILSON
    position would have understood the risk entailed in making
    rulings favorable to Echavarria. As detailed above, the FBI
    marshaled agents and resources from multiple offices and
    enlisted the assistance of the Mexican police. The FBI sent
    four agents to Echavarria’s interrogation in Mexico. The FBI
    provided information used in the confession that Echavarria
    signed the next morning. FBI personnel later translated the
    confession into English for the prosecution. The FBI’s
    involvement in the operation was so deep that Commandante
    Rubalcava, the deputy chief of the Mexican police in Juarez,
    later believed that he needed to “have a clearance” from the
    FBI in order to speak with Echavarria’s counsel. After
    Echavarria confessed, FBI agents gathered and analyzed
    critical evidence to be used at trial—witnesses, fingerprints,
    ballistics, and even glass fragments evaluated by an FBI
    forensic geologist.
    FBI agents testified at the suppression hearing in state
    court. At the conclusion of that hearing, Judge Lehman was
    required to choose between the FBI agents’ account of the
    interrogation and Echavarria’s. In all, twenty employees of
    the FBI testified during proceedings before Judge Lehman,
    many of them stressing the fact that Agent Bailey was an FBI
    agent.
    During voir dire, the prosecution emphasized that “[t]he
    murder victim was a special agent with the Federal Bureau of
    Investigation.” At trial, the prosecution began its opening
    statement the same way: “On[] the 25th of June, 1990, at
    about eleven forty-nine a.m., Special Agent John Bailey of
    the Federal Bureau of Investigation was inside the Security
    Pacific National Bank . . . . He was there on official
    business.” In its closing argument, the prosecution reiterated,
    “It would be easy enough to, after all this time, . . . to forget
    ECHAVARRIA V. FILSON                     29
    perhaps the very real reason we are all here and we’re all
    doing this. The very real reason we’re all here and we’re all
    doing this is shown in State’s exhibit number one, the
    photograph of Special Agent John Bailey of the Federal
    Bureau of Investigation.”
    Based on our de novo review, we hold that Echavarria’s
    right to due process was violated. Indeed, on the facts before
    us, we would so hold even if we were addressing the question
    under the deferential standard of AEDPA. For an average
    judge in Judge Lehman’s position there would have been a
    constitutionally intolerable risk of bias. An average judge in
    that position would have feared that rulings favoring
    Echavarria, tipping the outcome towards acquittal or a
    sentence less than death, could cost him his reputation, his
    judgeship, and possibly his liberty.
    The State argues that there was no risk of bias because
    federal and state authorities had previously declined to
    prosecute Judge Lehman. But the question before us is not
    whether, a few years before Echavarria’s trial, Judge Lehman
    had escaped prosecution. The question is whether an average
    judge in Judge Lehman’s position would have feared that the
    FBI might reopen its investigation or renew its advocacy for
    state prosecution if he made rulings favorable to Echavarria.
    The State also argues that Judge Lehman’s risk of bias
    was no different from that of “judges at all levels of the
    judicial system [who] are constantly asked to make rulings
    that could cut against the interests of state and federal law
    enforcement agencies.” That is plainly incorrect. Judge
    Lehman was no ordinary judge, and Echavarria was no
    ordinary defendant. Rather, Judge Lehman personally had
    been criminally investigated by the very FBI agent that
    30                ECHAVARRIA V. FILSON
    Echavarria was accused of killing, and the case required
    Judge Lehman to determine, inter alia, whether FBI agents
    had known about or been involved in the use of torture in
    obtaining Echavarria’s confession.
    In the circumstances of this case, the risk of bias was
    extraordinary in both its nature and severity. The risk was
    obvious to all who had complete information about Agent
    Bailey’s investigation. The FBI met with the prosecutors
    specifically to brief them on Agent Bailey’s investigation and
    prepare them for “in court and/or appeal motions based on
    due process and equal protection considerations and claiming
    judicial bias.” (Emphasis added.) Based on what was
    revealed in that meeting, the prosecutors appear to have
    recognized the importance of informing Echavarria of the
    investigation. Indeed, Chief Deputy District Attorney Henry
    promised to “suggest a chambers meeting to discuss this with
    all counsel present.” But that meeting never took place, and
    Echavarria never had the opportunity to request that Judge
    Lehman recuse.
    Conclusion
    The risk of bias in this case deprived Echavarria of the
    fair tribunal to which he was constitutionally entitled. We
    therefore affirm the district court’s grant of habeas relief.
    Because we affirm the district court on this ground, we do not
    reach the other questions presented in this appeal.
    AFFIRMED.
