    Appeal from the United States District Court
    for the Middle District of Florida
    ________________________
    (December 7, 2011)
    Before TJOFLAT, MARCUS, and MARTIN, Circuit Judges.
    MARTIN, Circuit Judge:
    We previously issued an opinion in this case. Guzman v. Sec'y, Dep't of
    Corr., ---F.3d---, 
    2011 WL 5083235
     (11th Cir. Oct. 27, 2011) (No. 10-11442).
    The panel has decided to vacate that opinion and substitute this one. The new
    opinion deletes three paragraphs but otherwise remains identical to the first.
    In this death penalty case, Respondents-Appellees appeal the District
    Court’s Order granting Petitioner Guzman a new trial based upon Brady1 and
    Giglio2 errors involving the State’s payment of $500 in reward money to Martha
    Cronin, the state’s key witness.3 As to the Giglio violation, Guzman argues that
    Cronin and the lead detective in this case, Allison Sylvester, both testified falsely
    at trial that Cronin received no benefit for her testimony against Guzman, other
    than being taken to a motel rather than to jail after she was arrested on unrelated
    charges. With respect to the Brady violation, Guzman contends that the State
    failed to disclose that Cronin was paid a $500 reward for her testimony. However,
    since we ultimately hold that the writ should issue based on Guzman’s Giglio

    Although Guzman raised a number of different habeas claims in the District Court

    claim, thereby vacating his conviction, we need not decide his Brady claim. See
    Cooper v. Sec’y, Dep’t of Corr., 
    646 F.3d 1328
    , 1331 n.1 (11th Cir. 2011).
    Because the Florida Supreme Court adjudicated and rejected Guzman’s
    Giglio claim on the merits, we must determine whether the District Court, in
    granting Guzman habeas relief, violated the Anti-Terrorism and Effective Death
    Penalty Act’s (AEDPA) deferential standards of review. More specifically, this
    appeal requires us to decide whether the state court’s decision:
    (1) resulted in a decision that was contrary to, or involved an
    unreasonable application of, clearly established Federal law, as
    determined by the Supreme Court of the United States; or (2) resulted
    in a decision that was based on an unreasonable determination of the
    facts in light of the evidence presented in the State court proceeding.
    
    28 U.S.C. § 2254
    (d)(1). Because we hold that Guzman demonstrated an
    unreasonable application by the state court of the Giglio standard, we affirm the
    District Court’s Order granting habeas relief.
    As a preliminary matter, we observe that in this case, there are no issues of
    procedural bar, exhaustion, statute of limitations, or non-retroactivity often
    encountered in habeas cases. Neither are the facts themselves in dispute. Our
    limited role here is to apply the “materiality” standard of Giglio, which is a
    question of law not entitled a presumption of correctness under 
    28 U.S.C. §
                                  3
    2254(e). Moon v. Head, 
    285 F.3d 1301
    , 1310–11 (11th Cir. 2002). We now turn
    to the facts underlying Guzman’s Giglio claim.
    I. FACTS AND PROCEDURAL HISTORY
    On December 13, 1991, Guzman was arrested for the murder of David
    Colvin. Guzman’s second trial began on December 2, 1996, and, in this trial,
    Guzman waived his right to a jury in both the guilt and penalty phases of the trial.4
    After a bench trial before the Honorable William C. Johnson, Circuit Judge,
    Guzman was found guilty of first degree murder and armed robbery with a deadly
    weapon.5 The trial court sentenced Guzman to death as to the murder count and to
    life imprisonment on the armed robbery count, with the sentences to run
    consecutively.6
    4
    Guzman was originally indicted on January 7, 1992, and, on September 25, 1992, a jury
    found Guzman guilty of robbery with a deadly weapon and first degree murder. Guzman was
    adjudicated guilty on both counts and sentenced to death on the murder conviction and to life
    imprisonment on the robbery conviction. The Florida Supreme Court subsequently reversed
    Guzman’s convictions and death sentence and remanded for a new trial, holding that Guzman’s
    right to a fair trial was violated because his public defender had a conflict of interest. See
    Guzman v. State, 
    644 So. 2d 996
    , 999 (Fla. 1994) (Guzman I).
    5
    Judge Johnson also presided over the postconviction evidentiary hearing and issued the
    trial court orders denying Guzman relief.
    6
    The Court stated:
    In its sentencing order, the trial court found the following five aggravating
    circumstances: (1) Guzman was previously convicted of a felony involving the use
    of violence; (2) the murder was committed in the course of a robbery; (3) the murder
    was committed for the purpose of avoiding arrest; (4) the murder was committed in
    a cold, calculated, and premeditated manner (CCP); and (5) the murder was
    4
    As described by the Florida Supreme Court, the State presented the
    following evidence implicating Guzman as Colvin’s murderer:
    Approximately one week prior to the murder, Guzman and Martha
    Cronin, a prostitute and crack cocaine addict, began living together at
    the Imperial Motor Lodge. Colvin also resided at the motel, and
    Guzman and Colvin became acquainted. On the morning of August 10,
    Colvin and Guzman left the hotel in Colvin’s car. Guzman and Colvin
    first proceeded to a tavern and drank beer, then the men went to the
    International House of Pancakes and ate breakfast. Guzman testified
    that he and Colvin returned to the motel at approximately 12 noon.
    Guzman stated that he gave Colvin’s car and room keys back to Colvin
    and returned to his room. Guzman testified that at approximately 3 p.m.
    Curtis Wallace gave him a diamond ring that he could sell or trade for
    drugs.7 Guzman admitted that he gave the ring to Leroy Gadson in
    exchange for drugs and money.8 However, Guzman denied any
    involvement in Colvin’s robbery and murder.
    Cronin’s trial testimony contradicted Guzman’s. Cronin testified
    that Guzman told her prior to the murder that Colvin would be easy to
    rob because he was always drunk and usually had money. Cronin stated
    that Guzman told her in another conversation that if he ever robbed
    anybody, he “would have to kill them” because “a dead witness can’t
    talk.” Cronin testified that Guzman was holding his survival knife at the
    time this statement was made. Cronin claimed that, on the morning of
    especially heinous, atrocious, or cruel (HAC).
    Guzman II, 721 So. 2d at 1158. The trial court found no statutory mitigating circumstances, and,
    as nonstatutory mitigation, the trial court found that Guzman’s alcohol and drug dependency was
    established but that it was entitled to little weight. Id.
    7
    While Guzman admitted that he possessed and sold Colvin’s ring, the record
    demonstrates he testified he got it from Cronin, not Wallace.
    8
    The State produced testimony at Guzman’s trial that he sold a ring belonging to Colvin
    to Gadson on August 10, 1991. Gadson testified that he was contacted by Guzman at
    approximately 4:00 or 5:00 p.m. on August 10, 1991.
    5
    August 10, Guzman told her that he was going to drive Colvin to the
    bank. Cronin stated that Guzman returned to their room that morning
    and showed her Colvin’s car keys and room keys. Cronin testified that
    at approximately 3 p.m. Guzman appeared at their room with a garbage
    bag that contained rags. Cronin said that Guzman looked upset, and that
    she asked him what was wrong. Cronin testified that Guzman
    responded, “I did it,” and confessed to murdering Colvin. Cronin stated
    that Guzman told her that Colvin awakened while he was taking money
    from Colvin’s room. Cronin testified that Guzman said that he hit
    Colvin in the head and then stabbed him with the samurai sword.
    Cronin stated that Guzman showed her a diamond ring and money that
    he had taken from Colvin.9 Cronin also stated that Guzman said he
    committed the murder for her.
    Upon questioning by the police shortly after the discovery of
    Colvin’s body, Guzman and Cronin both claimed to know nothing about
    the murder. In the latter part of November 1991, Cronin informed the
    police that Guzman had confessed to her that he killed Colvin. Cronin
    testified that Guzman had instructed her to tell the police that she knew
    nothing about the murder. Cronin also testified that she did not come
    forward earlier because Guzman threatened to harm her if she revealed
    what she knew about the crime. Guzman admitted that he told Cronin
    prior to his first trial to “do the right thing girl-it’s a small world.” Paul
    Rogers and Guzman became friends while sharing a jail cell in the
    Spring of 1992. Rogers testified that Guzman confessed to him that he
    9
    Apart from Cronin’s testimony, there was also evidence that Guzman possessed
    Colvin’s ring and traded it for drugs and money after Colvin was killed. But there were only two
    different factual versions of how Guzman came into possession of the ring on August 10, 1991,
    both of which were presented at Guzman’s trial: one from Cronin and one from Guzman. Cronin
    testified that Guzman showed her the ring when he came back to their motel room and confessed
    to killing Colvin. In contradiction, Guzman testified that Cronin turned a trick inside their motel
    room while he waited outside. After Cronin was finished, Guzman came into the room and
    Cronin gave him $50 and then told Guzman she was going to see Curtis Wallace and buy some
    drugs. Id. When Cronin returned, she had a ring in her hand and Wallace was with her.
    According to Guzman’s testimony, Cronin told Guzman that Wallace wanted to trade the ring for
    crack cocaine. Guzman testified that he believed that the ring belonged to Wallace and admits
    that he, Guzman, sold the ring to Leroy Gadson for $250 and a quantity of cocaine, which he
    shared with Wallace and Cronin.
    6
    robbed and killed Colvin. Rogers said that Guzman told him that he used
    Colvin’s key to enter his room after the men returned from drinking, and
    that Colvin awakened while Guzman was robbing him. Rogers further
    testified that Guzman stated that, after Colvin sat up in the bed, Guzman
    struck Colvin ten or eleven times with the sword. Rogers stated that
    Guzman said he cleaned the sword and put “everything” in a garbage
    bag which he disposed of in a dumpster. Rogers also stated that
    Guzman admitted that he took Colvin’s ring and some money and traded
    the ring for drugs. Guzman allegedly told Rogers that he robbed and
    killed Colvin so Cronin would not have to earn money as a prostitute.
    Rogers said that Guzman threatened to kill him and his family if he
    informed the police about his knowledge of the murder.
    Guzman II, 721 So. 2d at 1157–58. On direct appeal, the Florida Supreme Court
    affirmed Guzman’s convictions and sentences, although it held that the evidence
    did not support the cold, calculated, and premeditated aggravating circumstance.
    Id. at 1156. The United States Supreme Court denied certiorari. Guzman v.
    Florida, 
    526 U.S. 1102
    , 
    119 S. Ct. 1583
     (1999).
    After his direct appeal became final, Guzman filed a timely motion for
    postconviction relief pursuant to Florida Rule of Criminal Procedure 3.850, which
    he later amended to include a Brady and Giglio claim involving the false
    testimony of Cronin and the withholding of evidence from the defense concerning
    a $500 reward paid to Cronin. The state trial court granted Guzman an evidentiary
    hearing as to his Brady and Giglio claim, as well as a few others, and denied his
    remaining claims. In support of his various claims, Guzman presented the
    7
    testimony of eight witnesses and introduced several exhibits during the state
    evidentiary hearing. Martha Cronin did not testify at the evidentiary hearing.
    Based upon the facts adduced at trial and the state evidentiary hearing, the
    District Court summarized the following facts significant to Guzman’s Brady and
    Giglio claim:
    At trial, Detective [Allison] Sylvester testified that she questioned
    Ms. Cronin on August 12, 1991, and that Ms. Cronin failed to offer any
    information pertaining to the case. On September 24, 1991, Ms. Cronin
    was questioned by Detective Sylvester and, again, she denied any
    information about the homicide. [FN5] . . . Ms. Cronin provided a
    statement late on November 23, 1991, and into November 24, 1991, near
    midnight implicating Petitioner as the perpetrator of the homicide. Ms.
    Cronin had an active warrant for her arrest on November 24, 1991, due
    to an outstanding warrant for violation of probation. Ms. Cronin was
    seeking a “deal,” but the assistant state attorney handling the case
    instructed Detective Sylvester to arrest. Detective Sylvester rejected this
    directive and did not arrest Ms. Cronin. Instead, Ms. Cronin was taken
    to a hotel and provided with food, which was paid for by the Daytona
    Beach Police Department, in order to keep “an eye on her while [they]
    finished [up] following up . . . information.” However, Ms. Cronin left
    the hotel on November 24, 1991, without permission, and law
    enforcement lost contact with her. Ms. Cronin engaged in prostitution
    and used crack cocaine after she left the hotel.
    FN5. Ms. Cronin confirmed in her trial testimony that she
    told law enforcement on August 12, 1991, and on
    September 24, 1991, that she knew nothing about the
    homicide.
    Detective Sylvester then arrested Ms. Cronin on November 27,
    1991, for outstanding warrants for violation of probation. When Ms.
    Cronin was arrested on November 27, 1991, Detective Sylvester was
    8
    afraid that Ms. Cronin would flee, and Detective Sylvester admitted that
    Ms. Cronin was arrested because she was the prime witness and was
    needed for the case. Ms. Cronin was, nevertheless, released from jail on
    December 5, 1991.Petitioner was arrested on December 13, 1991.
    Ms. Cronin testified before the grand jury against Petitioner on
    January 11, 1992. At the trial, Detective Sylvester denied that she, law
    enforcement, or the State Attorney’s office had offered [Ms. Cronin] any
    deals in exchange for her testimony. Ms. Cronin also denied ever
    receiving a deal from law enforcement, although she acknowledged
    being placed in a hotel room for protection.
    At the Rule 3.850 evidentiary hearing, however, after defense
    investigation had revealed a payment had been made to Ms. Cronin,
    Detective Sylvester conceded that, on January 3, 1992, just eight days
    before Ms. Cronin testified before the grand jury she delivered a money
    order to the Volusia County Jail in the sum of $500 made payable to Ms.
    Cronin. The money was placed in Ms. Cronin’s prison account where
    she was incarcerated and was provided to her because she had provided
    information leading to the arrest of Petitioner. Detective Sylvester
    denied that Ms. Cronin was paid for her testimony. Detective Sylvester
    could not recall when the reward money had first been offered to Ms.
    Cronin. However, the reward was originally offered on August 16,
    1991, for information “about a man stabbed to death in his motel room.”
    The reward offer was published in the Daytona Beach News-Journal and
    the Orlando Sentinel. Detective Sylvester recalled that Ms. Cronin’s
    mother contacted her on January 2, 1992, “asking if it were possible for
    [Detective Sylvester] to obtain the reward money to get it to [Ms.
    Cronin] in case she got out when she went to court that day.” Detective
    Sylvester testified that she had not disclosed to the prosecuting attorney
    the $500 reward paid to Ms. Cronin. The prosecutor denied any
    knowledge of the $500 reward.
    Guzman v. Sec’y, Dep’t Corrs., 
    698 F. Supp. 2d 1317
    , 1322–23 (M.D. Fla. 2010)
    (citations omitted).
    9
    After the state court evidentiary hearing, the trial court denied all of
    Guzman’s remaining claims, including his Giglio claim in a written Order on
    March 4, 2002. In rejecting Guzman’s Brady and Giglio claims, the state trial
    court used the same materiality standard for both claims, stating:
    This Court finds that these allegations do not satisfy the tests for
    a sufficient Brady, Giglio, or ineffective assistance of counsel claim.
    Trial counsel extensively cross-examined Cronin, for over 88 pages of
    trial transcripts . . . . Thus, this Court was aware of the fact that Cronin
    had made an agreement with the State to testify against Defendant.
    Further, there was other evidence of Defendant’s guilt apart from
    Cronin’s testimony.
    Therefore, this Court finds that there is not a reasonable
    probability that had the information regarding the $500.00 reward paid
    to Cronin been disclosed to Defendant, the result of the proceeding
    would have been different. Further, this Court finds that this statement
    regarding the $500.00 reward being paid to Cronin is immaterial
    because there is not a reasonable probability that the false evidence
    would put the whole case in such a different light as to undermine the
    confidence in the verdict.
    Guzman appealed to the Florida Supreme Court and separately filed a state
    petition for writ of habeas corpus. The Florida Supreme Court remanded
    Guzman’s Giglio claim to the trial court because that court’s “resolution of the
    Giglio claim [did] not sufficiently reflect the standard appropriate to a Giglio
    claim” inasmuch as the trial court’s order failed to adequately distinguish between
    the Brady standard and the Giglio standard in considering and deciding the Giglio
    10
    claim. Guzman v. State, 
    868 So. 2d 498
    , 507 (Fla. 2003) (Guzman III). The
    Florida Supreme Court denied the remaining claims in both the appeal and the
    petition for writ of habeas corpus, including Guzman’s Brady claim. 
    Id.
     at
    508–11. With respect to the Brady claim, the court identified the federal Brady
    standard and held that the $500 was favorable evidence as impeachment against
    Cronin. 
    Id. at 508
    . The court also determined that the evidence was suppressed,
    noting Guzman had filed a “specific discovery demand requesting from the State
    all agreements or any consideration given to a State witness, and the State’s
    written response stated that Cronin received no ‘agreements, assurances of
    nonprosecution or leniency, offers, benefits or understandings.’”10 
    Id.
     But the
    10
    On June 25, 1996, several months before trial, Guzman’s counsel filed a motion for
    disclosure of impeachment evidence. In that motion, Guzman specifically requested disclosure
    of the following:
    1. The substance of any and all statements, agreements, offers or discussions
    had with any of the State’s witnesses or a suggestion of . . . compensation . . . or any
    other offer to benefit accruing to said individual whatsoever in exchange for their
    cooperation, assistance of testimony of testimony in the trial herein.
    2. Any and all consideration or promises of consideration given to or made
    on behalf of government witnesses. By ‘consideration,’ [Guzman] refers to
    absolutely anything of value or use . . . and anything else which could arguably create
    an interest or bias in the witness i[n] favor of the State or against the defense or act
    as an inducement to testify or to color testimony.
    On December 2, 1996, the first day of Guzman’s retrial, the state filed a Statement of Particulars
    re: State Witnesses, which stated, in relevant part: “[t]hat Martha Cronin has been subpoenaed as
    a witness for trial in this cause and, as such, has use immunity for her testimony. There are no
    further agreements, assurances of non-prosecution or leniency, offers, benefits, or understandings
    between the State of Florida and Martha Cronin.”
    11
    state court denied relief because it determined that although the State suppressed
    favorable impeachment evidence, the withheld evidence was not material. 
    Id.
     at
    508–09.
    On remand, the trial court once again denied Guzman relief on his Giglio
    claim in a written order finding that the evidence was immaterial under Giglio
    “due to the ample impeachment and corroboration of Cronin’s testimony, and the
    independent evidence of [Guzman’s] guilt.” The trial court also determined that
    the false evidence was harmless beyond a reasonable doubt. In support, the trial
    court explained:
    The Court determines that in light of the significant impeachment
    evidence presented at trial and the other evidence of Guzman’s guilt, the
    evidence of the State’s $500.00 reward to Martha Cronin would have
    been merely cumulative and immaterial. The record herein contains
    other evidence of Guzman’s guilt apart from Cronin’s testimony.
    Dr. Terrance Steiner, then interim medical examiner for Volusia
    County, testified at trial that Colvin’s sword recovered from the room
    could have inflicted some of the wounds to Colvin’s body, and that
    Guzman’s survival knife could have inflicted other wounds to Colvin’s
    body.
    Paul Rogers, the jailhouse witness who shared a jail cell with
    Guzman, corroborated Cronin’s testimony. Paul Rogers testified that
    Guzman confessed to him that he robbed and killed Colvin. The record
    reflects that it is undisputed that Guzman possessed Colvin’s ring and
    traded it for drugs and cash.
    12
    Guzrnan’s trial counsel presented significant impeachment
    evidence against Cronin during cross-examination. Specifically, Cronin
    was impeached on: her initial claim to know nothing about Colvin’s
    murder upon questioning by the police after the discovery of Colvin’s
    body; her attempt to make a deal with the State after her arrest, in
    exchange for her damaging testimony against Guzman; her
    discontentment with Guzman’s association with other female
    acquaintances; her numerous arrests for prostitution; her addiction to
    crack cocaine.
    Guzman also presented the testimony at trial from Carmelo
    Garcia. Garcia testified that Cronin told him she had lied to the police
    about Guzman murdering Colvin.
    After evaluating the State’s $500 payment to Cronin in light of the
    other evidence presented at trial, the Court concludes that the evidence
    of the $500 payment to Cronin was immaterial under Giglio. The Court
    concludes that there was no reasonable likelihood that the false
    testimony regarding the $500 payment to Cronin could have affected the
    court’s judgment as factfinder.
    The Florida Supreme Court affirmed the trial court’s denial of Guzman’s
    Giglio claim in a written opinion. Guzman v. State, 
    941 So. 2d 1045
     (Fla. 2006)
    (Guzman IV). After identifying the Giglio standard, the court determined that the
    evidence was immaterial.11 
    Id.
     at 1050–52.
    Guzman timely filed a federal petition for writ of habeas corpus pursuant to
    
    28 U.S.C. § 2254
     in the District Court for the Middle District of Florida, in which
    he raised a number of constitutional claims, including his Brady and Giglio claims.
    11
    The Florida Supreme Court’s statement of reasons in support of its decision will be
    discussed in greater detail below.
    13
    After briefing by the parties, and without an evidentiary hearing, the District Court
    granted Guzman a new trial based upon his Brady and Giglio claims and denied
    relief on his remaining claims.12 See Guzman, 
    698 F. Supp. 2d at
    1333–35. In
    granting habeas relief, the District Court determined that the Florida Supreme
    Court had correctly identified Brady and Giglio as providing the standard for
    adjudication of Guzman’s claims. 
    Id.
     But after carefully reviewing the factual
    record developed in the state court proceedings, both at trial and in postconviction,
    the District Court found that the false testimony was material under both Brady
    and Giglio. 
    Id.
     Further, the court found that Guzman had shown the testimony
    was not harmless beyond a reasonable doubt and that it had a substantial injurious
    effect in determining the trial court’s verdict. 
    Id.
     The District Court therefore
    concluded that Guzman had shown that the decision of the Florida Supreme Court
    was contrary to, or an unreasonable application of, clearly established federal law,
    as determined by the United States Supreme Court and was otherwise based on an
    unreasonable determination of the facts in light of the evidence presented. 
    Id.
     at
    1333–35.
    12
    The District Court decided Guzman’s claim based exclusively upon the facts which
    were developed in the State court proceedings without holding a federal evidentiary hearing.
    Like the District Court, our review under 
    28 U.S.C. § 2254
    (d)(1) is limited to the record that was
    before the State court that adjudicated Guzman’s claim on the merits. See Cullen v. Pinholster,
    ---U.S.---, ---, 
    131 S. Ct. 1388
    , 1398 (2011).

    A district court’s grant or denial of a habeas corpus petition is reviewed de
    novo. Ward v. Hall, 
    592 F.3d 1144
    , 1155 (11th Cir. 2010). Because Guzman
    filed his federal petition after April 24, 1996, this case is governed by 
    28 U.S.C. § 2254
    , as amended by the Anti-Terrorism and Effective Death Act of 1996
    (AEDPA). See Henderson v. Campbell, 
    353 F.3d 880
    , 889–90 (11th Cir. 2003).
    AEDPA “imposes a highly deferential standard for evaluating state-court rulings”
    and “demands that state-court decisions be given the benefit of the doubt.” Renico
    v. Lett, ---U.S.---, ---, 
    130 S. Ct. 1855
    , 1862 (2010) (quotation marks omitted).
    Because Guzman seeks habeas relief under 
    28 U.S.C. § 2254
     based upon claims
    that were adjudicated on the merits by the state courts, we are restricted in our
    ability to grant relief by § 2254(d). Cave v. Sec’y, Dep’t of Corrs., 
    638 F.3d 739
    ,
    742 (11th Cir. 2011). To grant Guzman’s habeas petition, we must find not only
    that Guzman’s constitutional claims are meritorious, but also that the state court’s
    resolution of those claims:
    (1) resulted in a decision that was contrary to, or involved
    an unreasonable application of, clearly established Federal
    law, as determined by the Supreme Court of the United
    States; or
    15
    (2) resulted in a decision that was based on an
    unreasonable determination of the facts in light of the
    evidence presented in the State court proceeding.
    
    28 U.S.C. § 2254
    (d); see also Cave, 638 F.3d at 742–43. The Supreme Court has
    recognized that § 2254(d)(1)’s “contrary to” and “unreasonable application”
    clauses have independent meaning. Bell v. Cone, 
    535 U.S. 685
    , 694, 
    122 S. Ct. 1843
    , 1850 (2002).
    A state court’s decision is “contrary to” clearly established Supreme Court
    precedent in either of two respects: (1) “if the state court applies a rule that
    contradicts the governing law set forth in [Supreme Court] cases,” or (2) “if the
    state court confronts a set of facts that are materially indistinguishable from a
    decision of [the Supreme] Court and nevertheless arrives at a result different from
    [the Supreme Court’s] precedent.” Williams v. Taylor, 
    529 U.S. 362
    , 405–06, 
    120 S. Ct. 1495
    , 1519–20 (2000).
    To determine whether a state court decision is an “unreasonable
    application” of clearly established federal law, the Supreme Court recently stated:
    The pivotal question is whether the state court’s application of the
    [relevant constitutional] standard was unreasonable . . . . For purposes
    of § 2254(d)(1), an unreasonable application of federal law is different
    from an incorrect application of federal law. A state court must be
    granted a deference and latitude that are not in operation when the case
    involves review under the [relevant constitutional] standard itself.
    16
    A state court’s determination that a claim lacks merit precludes federal
    habeas relief so long as fairminded jurists could disagree” on the
    correctness of the state court’s decision. And as the [Supreme Court]
    has explained, evaluating whether a rule application was unreasonable
    requires considering the rule’s specificity. The more general the rule, the
    more leeway courts have in reaching outcomes in case-by-case
    determinations.
    Harrington v. Richter, --- U.S. ---, ---, 
    131 S. Ct. 770
    , 785–86 (2011) (citation and
    quotation marks omitted) (emphasis in original).
    In addition, a state court’s factual determination is entitled to a presumption
    of correctness. 
    28 U.S.C. § 2254
    (e)(1). The AEDPA’s “statutory presumption of
    correctness applies only to findings of fact made by the state court, not to mixed
    determinations of law and fact.” Parker v. Head, 
    244 F.3d 831
    , 836 (11th Cir.
    2001); Hallford v. Culliver, 
    459 F.3d 1193
    , 1199 (11th Cir. 2006). A
    determination of “materiality” for a Brady violation is a question of law not
    entitled to a presumption of correctness. Moon, 
    285 F.3d at
    1310–11.
    Ultimately, before a federal court may grant habeas relief under § 2254(d),
    “a state prisoner must show that the state court’s ruling on the claim being
    presented in federal court was so lacking in justification that there was an error
    well understood and comprehended in existing law beyond any possibility for
    fairminded disagreement.” Harrington, ---U.S. at ---, 131 S. Ct. at 786–77. In
    order to make this determination under § 2254(d),
    17
    a habeas court must determine what arguments or theories supported or,
    as here, could have supported, the state court’s decision; and then it
    must ask whether it is possible fairminded jurists could disagree that
    those arguments or theories are inconsistent with the holding in a prior
    decision of this Court.
    Id. at 786 (emphasis added). We emphasize, however, that Ҥ 2254(d) does not
    require a state court to give reasons before its decision can be deemed to have
    been adjudicated on the merits.” Id. at ---, 131 S. Ct. at 785 (quotation marks
    omitted). But where the state courts have taken the time and resources to issue an
    opinion explaining their decision, a federal court must consider it and give it
    deference.13 ” Id. at ---, 131 S. Ct. at 786–77.
    13
    Indeed, since AEDPA became law, federal courts have expressly considered the
    reasoning of state courts in determining that a state court’s decision was contrary to, or an
    unreasonable application of, clearly established federal law under 
    28 U.S.C. § 2254
    (d). See, e.g.,
    Porter v. McCullom, --- U.S. ---, ---, 
    130 S. Ct. 447
    , 454 (2009) (finding the Florida Supreme
    Court’s explicated decision in Porter v. State, 
    788 So. 2d 917
     (2001), was an unreasonable
    application of the general Strickland standard, where the state court “either did not consider or
    unreasonably discounted the mitigation evidence adduced in the postconviction hearing”); Early
    v. Packer, 
    537 U.S. 3
    , 8, 
    123 S. Ct. 362
    , 365 (2002) (per curiam) (indicating that § 2254 does not
    preclude relief if either “the reasoning [or] the result of the state-court decision contradicts [our
    cases]”); Williams, 
    529 U.S. at 407-08
    , 
    120 S. Ct. at 1520
     (stating application unreasonable
    where state court “correctly identifies the governing legal rule but applies it unreasonable to the
    facts of a particular prisoner’s case”); Smith, 
    572 F.3d 1327
     (carefully examining Florida
    Supreme Court’s written decision which had denied capital habeas petitioner relief on Brady and
    Giglio claims, then holding that state court’s rejection of petitioner’s Brady claim was
    unreasonable); Ventura v. Atty. Gen., Fla., 
    419 F.3d 1269
    , 1281–82 (11th Cir. 2005) (analyzing
    a Giglio claim under § 2254(d) and stating “whether the state court reached a conclusion of law
    that contradicts one reached by the Supreme Court-requires a careful analysis of the Florida
    Supreme Court’s decision”).
    18
    Finally, a habeas petition will only be granted if the Constitutional violation
    at the trial level resulted in “actual prejudice” to the petitioner. Brecht v.
    Abrahamson, 
    507 U.S. 619
    , 637, 
    113 S. Ct. 1710
    , 1722 (1993). The alleged error
    must have had a “substantial and injurious effect or influence in determining the
    jury’s verdict.” 
    Id.
     at 637–38, 
    113 S. Ct. at
    1722–33 (quotation marks omitted).
    III. DISCUSSION
    We begin by noting that the “clearly established federal law” relevant to
    Guzman’s claims was firmly established by United States Supreme Court holdings
    long before Guzman’s trial and postconviction proceedings.14 As long ago as
    Mooney v. Holohan, 
    294 U.S. 103
    , 112, 
    55 S. Ct. 340
    , 342 (1935), the Supreme
    Court made clear that deliberate deception of a court and jurors by the presentation
    of known false evidence is incompatible with “rudimentary demands of justice.”
    In Napue v. Illinois, 
    360 U.S. 264
    , 269, 
    79 S. Ct. 1173
    , 1177 (1959), the Supreme
    Court explained, “[t]he same result obtains when the State, although not soliciting
    false evidence, allows it to go uncorrected when it appears.” Thereafter, Brady v.
    Maryland, 
    373 U.S. 83
    , 87, 
    83 S. Ct. 1194
    , 1196–97 (1963), held that “the
    14
    The phrase “clearly established Federal law” in §2254(d)(1) encompasses only the
    holdings of the United States Supreme Court “as of the time of the relevant state-court decision.”
    Williams, 
    529 U.S. at 412
    , 
    120 S. Ct. at 1523
    ; see also Schwab v. Crosby, 
    451 F.3d 1308
    , 1324
    (11th Cir. 2006).
    19
    suppression by the prosecution of evidence favorable to an accused upon request
    violates due process where the evidence is material either to guilt or to
    punishment, irrespective of the good faith or bad faith of the prosecution.” “When
    the ‘reliability of a given witness may well be determinative of guilt or innocence,’
    nondisclosure of evidence affecting credibility falls within this general rule.”15
    Giglio, 
    405 U.S. at 154
    , 
    92 S. Ct. at
    766 (citing Napue, 
    360 U.S. at 269
    , 
    79 S. Ct. at 1177
    ). But we do not “automatically require a new trial whenever a combing of
    the prosecutors’ files after the trial has disclosed evidence possibly useful to the
    defense but not likely to have changed the verdict.” 
    Id.
     (quotation mark omitted).
    “A finding of materiality of the evidence is required under Brady.” 
    Id.
    Guzman claims that there was both a Giglio violation and a Brady violation
    at his trial. Although the two claims are related, each claim is different and has its
    “own standard for determining whether the undisclosed evidence [was] material.”
    Smith, 
    572 F.3d at
    1333– 34. As noted above, we only decide Guzman’s Giglio
    claim in this opinion.
    15
    In 1976, the Supreme Court clearly established that “a defendant need not request
    favorable evidence from the State to be entitled to it.” Smith v. Sec’y Dept. Corrs., 
    572 F.3d 1327
    , 1333 -1334 (11th Cir. 2009) (citing United States v. Agurs, 
    427 U.S. 97
    , 103–07, 
    96 S. Ct. 2392
    , 2397–99 (1976).
    20
    To establish a Giglio claim, a habeas petitioner must prove: “(1) the
    prosecutor knowingly used perjured testimony or failed to correct what he
    subsequently learned was false testimony; and (2) such use was material, i.e., that
    there is any reasonable likelihood that the false testimony could . . . have affected
    the judgment.” Ford v. Hall, 
    546 F.3d 1326
    , 1332 (11th Cir. 2008) (quotation
    marks omitted). For Giglio violations, the defendant is entitled to a new trial “if
    there is any reasonable likelihood that the false testimony could have affected the
    judgment of the jury.”16 Agurs, 
    427 U.S. at 103
    , 
    96 S. Ct. at 2397
    . “The could
    have standard requires a new trial unless the prosecution persuades the court that
    the false testimony was harmless beyond a reasonable doubt.” Smith, 
    572 F.3d at
    1333–34. Giglio’s materiality standard is “more defense-friendly” than Brady’s.
    Hammond v. Hall, 
    586 F.3d 1289
    , 1306 n.4 (11th Cir. 2009).
    16
    Although Giglio’s materiality standard is stated in general terms and the Florida
    Supreme Court correctly identified the standard, that does not mean its “application was
    reasonable.” Panetti, 551 U.S. at 953, 127 S. Ct. at 2858. As the Supreme Court has explained
    with respect to § 2254(d)’s unreasonable application prong:
    AEDPA does not require state and federal courts to wait for some nearly identical
    factual pattern before a legal rule must be applied. Nor does AEDPA prohibit a
    federal court from finding an application of a principle unreasonable when it involves
    a set of facts different from those of the case in which the principle was announced.
    The statute recognizes, to the contrary, that even a general standard may be applied
    in an unreasonable manner.
    Id. at 953, 127 S. Ct. at 2858 (citations and quotation marks omitted).
    21
    By comparison, in Guzman’s case, the Florida Supreme Court stated the
    Giglio test as follows: “[t]o establish a Giglio violation, it must be shown that: (1)
    the testimony given was false; (2) the prosecutor knew the testimony was false;
    and (3) the statement was material.” Guzman IV, 
    941 So. 2d at 1050
     (citations
    omitted). This formulation of the Giglio test is substantially the same as ours,
    except we combine the state court’s first and second component into our first
    prong. Because the Florida Supreme Court correctly identified the governing legal
    principle from the Supreme Court’s decisions and we have not identified a
    Supreme Court case with materially indistinguishable facts, we must determine
    whether the state court unreasonably applied it to Guzman’s facts. Bell, 
    535 U.S. at 694
    , 
    122 S. Ct. at 1850
    .
    The Florida Supreme Court held that “[t]he first two prongs of the Giglio
    test are satisfied in this case.” Guzman III, 
    868 So. 2d at 505
    ; Guzman IV, 
    941 So. 2d at 1050
    . The Florida Supreme Court explained its conclusion:
    Both Cronin and [Detective Sylvester] testified falsely at trial that
    Cronin received no benefit for her testimony against Guzman other than
    being taken to a motel rather than jail when she was arrested. In fact, the
    State paid Cronin $500, a significant sum to an admitted crack cocaine
    addict and prostitute. The knowledge prong is satisfied because the
    knowledge of the detective who paid the reward money to Cronin is
    imputed to the prosecutor who tried the case.
    22
    Guzman III, 
    868 So. 2d at 505
     (citations omitted). We agree with the Florida
    Supreme Court’s conclusions with respect to Giglio’s first two prongs. Here, the
    record fully supports that Cronin and Detective Sylvester testified falsely at
    Guzman’s trial that Cronin received no benefit other than being taken to a motel
    and not arrested, yet Cronin was in fact paid a $500 reward. Although Detective
    Sylvester testified at the postconviction hearing that she could not recall if she
    disclosed to the trial prosecutor that she had paid Cronin a $500 reward,
    Sylvester’s knowledge of this evidence was imputed to the prosecutor. See Kyles
    v. Whitley, 
    514 U.S. 419
    , 437–38, 
    115 S. Ct. 1555
    , 1567–68 (1995) (holding that
    a “prosecutor has a duty to learn of any favorable evidence known to the others
    acting on the government’s behalf in the case, including the police. But whether
    the prosecutor succeeds or fails in meeting this obligation . . . the prosecution’s
    responsibility for failing to disclose known, favorable evidence . . . is
    inescapable.”).
    However, after carefully reviewing the transcripts from Guzman’s trial and
    evidentiary hearing and the trial court’s orders, we hold that the Florida Supreme
    Court’s materiality determination was more than just incorrect—it was an
    objectively unreasonable application of clearly established Supreme Court
    precedent. The state trial court initially found that “there was [not] a reasonable
    23
    probability that the false evidence would put the whole case in such a different
    light as to undermine confidence in the verdict.” On appeal, the Florida Supreme
    Court found that its precedent with respect to Brady and Giglio “lacked clarity,”
    which resulted in “some confusion and merging of the Giglio and Brady
    materiality standards.” Guzman, 
    868 So. 2d at 506
    . The Florida Supreme Court
    then clarified the two standards and remanded the case to the trial court for
    reconsideration of Giglio’s materiality standard, which it clarified as, “whether
    there is any reasonable likelihood that the false testimony could have affected the
    court’s judgment as the factfinder in this case.” 
    Id.
    On remand, the trial court found that the State’s $500 payment to Cronin
    was immaterial under Giglio. As noted above, the trial court “determin[ed] that
    there [was] no reasonable likelihood that the false testimony could have affected
    the judgment of the [c]ourt and that the State had met its burden of showing that
    the false evidence was “harmless beyond a reasonable doubt.” The Florida
    Supreme Court affirmed, reasoning as follows:
    The circuit judge denied Guzman’s claim on the grounds that the
    false testimony was not material. To affirm this determination, we have
    to conclude that there is no reasonable possibility that the false
    testimony of Cronin and Detective Sylvester regarding the $500 reward
    affected the verdict. That standard has been met here. For the reasons
    relied upon by the trial court, we conclude that the State has established
    24
    beyond a reasonable doubt that the false testimony of the witnesses had
    no effect on the verdict.
    The trial court found Cronin’s credibility as a witness was amply
    impeached and that Cronin’s testimony incriminating Guzman was
    independently corroborated and supported at trial. Our own de novo
    review of the record supports these conclusions. Indeed, impeachment
    of Cronin was substantial. She testified about her crack cocaine
    addiction, numerous arrests for prostitution, and agreement to testify
    against Guzman in exchange for a lesser charge on prostitution. She also
    acknowledged that she told witness Garcia that Guzman had not killed
    anyone but that she had lied to the police in accusing Guzman because
    she had been arrested and that she was angry with Guzman over his
    relations with other women. The judge also received evidence that the
    State had paid for a motel room and meals for Cronin. [FN3] In light of
    this ample impeachment, the circuit judge was justified in concluding
    that Cronin[’s] and Detective Sylvester’s false testimony regarding the
    $500 reward was of “limited significance” and “merely cumulative and
    immaterial.” We agree with this conclusion. The addition of the
    truthful testimony about the $500 reward would not have made a
    material difference in Cronin’s credibility to the finder of fact.
    FN3. Notably, during the evidentiary hearing on the initial
    postconviction motion, Guzman’s defense counsel revealed
    that, prior to trial, Guzman made him aware of allegations
    that Cronin had received the $500. Defense counsel chose
    not to pursue discovery or questioning at trial regarding the
    allegations.
    Guzman IV, 
    941 So. 2d at
    1050–52 (footnote omitted).
    Like the District Court, we fully recognize that Cronin was impeached
    during her trial testimony by defense counsel. See Guzman, 
    698 F. Supp. 2d at
    1331–32. But even taking this impeachment evidence into account, it was
    25
    objectively unreasonable for the state court to conclude that Cronin’s
    impeachment was so complete that “there is no reasonable possibility that the false
    testimony regarding the $500 reward could have affected the judgment of the
    factfinder.” Guzman IV, 
    941 So. 2d at 1051
    .
    As the Florida Supreme Court observed, a payment of $500 is a significant
    sum to an admitted crack addict. Guzman III, 
    868 So. 2d at 505
    ; see also Guzman
    IV, 
    941 So. 2d at 1056
     (Anstead, J., dissenting). We agree with the District
    Court’s conclusion that the $500 payment would have provided “substantial and
    specific evidence of Ms. Cronin’s motivation to lie against [Guzman]:”
    The $500 payment was more than just another avenue of impeachment
    against an already discredited witness. The fact that the lead detective
    and the lead witness twice denied the existence of the payment is at least
    a tacit admission that it was perceived to have relevance to a reasonable
    fact finder viewing the credibility of this witness.
    Guzman, 
    698 F. Supp. 2d at 1332
    . The state court’s conclusion to the contrary is
    objectively unreasonable for several reasons.
    First, we are mindful that the Florida Supreme Court’s materiality
    determination also relied upon a finding that Cronin’s testimony regarding
    Guzman’s guilt was independently corroborated and supported by other evidence.
    See Guzman IV, 
    941 So. 2d at 1051
    . In support, the Florida Supreme Court relied
    upon the following:
    26
    [i]n particular, the testimony of both Dr. Steiner and Rogers supports the
    circuit judge’s finding. Dr. Steiner, the medical examiner, supported
    Cronin’s testimony at trial by testifying that the samurai sword and the
    survival knife could have caused the victim’s injuries. Rogers, the
    jailhouse witness who shared a cell with Guzman, testified that Guzman
    admitted committing the crime. It is also undisputed that, shortly after
    the murder, Guzman sold the victim’s ring to Leroy Gadson, a known
    drug dealer, for drugs and cash. This evidence of Guzman’s guilt,
    wholly independent of Cronin, supports her testimony. In light of this
    independent and corroborating evidence, we conclude that there is no
    reasonable possibility that the false testimony regarding the $500 reward
    could have affected the judgment of the factfinder
    
    Id.
     But we must also consider the cumulative effect of the false evidence for the
    purposes of materiality. Kyles, 
    514 U.S. at
    436–7 n.10, 
    115 S. Ct. at
    1567 n.10;
    Smith, 
    572 F.3d at 1334
    . “Considering the undisclosed evidence cumulatively
    means adding up the force of it all and weighing it against the totality of the
    evidence that was introduced at the trial.” 
    Id.
     (emphasis added). Thus, we must
    also consider the fact that Rogers was a seven-time convicted felon and recanted
    before trial, providing an affidavit under oath on August 26, 1992, stating that
    Guzman “had never confessed to me about the case.” Significantly, Rogers was
    aware of and had access to Guzman’s court records about the case in his cell.
    Also, as explained above, Guzman admitted to possessing and selling Colvin’s
    ring, but testified he got if from Cronin. Further, although the Florida Supreme
    Court viewed the medical examiner’s testimony as important, we must also
    27
    consider that “the medical examiner also testified that the victim’s wounds were
    ‘consistent with any knife three to four inches at least in length or knife-like
    object’ and that he was unable to identify the ‘exact weapon that may have
    inflicted a particular wound.’” See Guzman, 
    698 F. Supp. 2d at 1335
    .
    Additionally, although the degree to which Cronin may have been
    impeached at trial is relevant to the materiality inquiry, we emphasize “the effect
    of these other means of impeachment was not, however, to render” evidence of
    Cronin’s reward and perjury cumulative.17 See Ventura, 419 F.3d at 1291 n.9;
    United States v. Sanfilippo, 
    564 F.2d 176
    , 178 (5th Cir. 1977) (“The fact that the
    history of a witness shows that he might be dishonest does not render cumulative
    evidence that the prosecution promised immunity for testimony. A jury may very
    well give great weight to a precise reason to doubt credibility when the witness
    17
    In Ventura, this Court denied a habeas petitioner’s Giglio claim after finding the state
    court’s rejection of that claim was not contrary to, or an unreasonable application of, clearly
    established federal law. 419 F.3d at 1269. More specifically, Ventura determined that the state
    court’s conclusion that Ventura’s Giglio claim was not material was not “‘objectively
    unreasonable’ in light of the extensive and powerful corroborating evidence introduced and the
    substantial impeachment” of the witness. Id. at 1286. In so doing, Ventura expressly recognized
    the context-specific nature of Giglio claims. Id. Because Guzman’s case lacks “extensive and
    powerful corroborating” evidence as demonstrated throughout this opinion, the context in
    Guzman’s case is radically different from Ventura.

    785 F.2d 1457
     (11th Cir. 1986).
    Second, the Florida Supreme Court’s materiality determination
    unreasonably discounted not only the fact that Cronin was the State’s key witness
    in the case, but also the fact that her credibility was critical to the State’s case
    against Guzman. One need only read the Florida Supreme Court’s assessment of
    the evidence in Guzman’s direct appeal opinion, as set forth above, supra at 5–6,
    to confirm that Cronin’s testimony was critical to the State’s case. Guzman II, 721
    So. 2d at 1157–58. Most importantly, Cronin’s trial testimony was especially
    significant because it directly contradicted Guzman’s trial testimony in a manner
    that can only be considered material to the question of Guzman’s guilt by fair
    minded jurists. Guzman testified on his own behalf and denied his participation in
    any respect with this robbery–murder. Id. at 1157. As set out above, although
    Guzman admitted that he possessed and sold Colvin’s ring, he claimed he got it
    from Cronin. Cronin’s testimony was inapposite in all material respects. Id.; see
    also, Guzman, 
    941 So. 2d at 1056
     (Anstead, J., dissenting) (“The bottom line is
    that Cronin was the key witness in the case and the credibility of her testimony

    , 1209 (11th Cir. 1981) (en banc), this
    Court adopted as binding precedent all decisions of the former Fifth Circuit handed down before
    the close of business on September 30, 1981.
    29
    was critical to the State’s case against Guzman.”). But the state courts failed to
    consider the reasonable likelihood that an objective factfinder could have
    reasonably disbelieved Cronin’s testimony because of the $500 reward and
    because her prior statements were quite different from what she said at trial, and
    instead, given sufficient credence to Guzman’s testimony to have affected the
    judgment of the factfinder. Moreover, the critical nature of Cronin’s testimony is
    underscored by the simple fact that the State’s case connecting Guzman to
    Colvin’s murder was mostly testimonial.
    Furthermore, while the record is not clear about exactly when Cronin
    learned about the reward, the record is clear that on August 12, 1991, Cronin told
    law–enforcement that she did not have any information about Colvin’s murder.
    The record is also clear that the reward was published in the newspaper on August
    16, 1991 and that Cronin’s story changed after notice of the reward was
    published.19 Cronin first implicated Guzman as the perpetrator of Colvin’s
    murder on November 23-24, 1991. And it is equally clear that Detective Sylvester
    19
    Cronin was interviewed by Detective Sylvester at the Imperial Motor Lodge on August
    12, 1991, and did not implicate Guzman. On August 16, 1991, the State published in two local
    newspapers a reward offer of $500 for information about Colvin’s case. During the evidentiary
    hearing, Detective Sylvester testified that she could not recall if Cronin knew about the $500
    reward at the time of her November 23–24, 1991 statement.
    30
    deposited the reward money into Cronin’s inmate account on January 3, 1992, just
    days before Cronin testified before the grand jury.
    Given these indisputable facts, Guzman’s defense attorney could have
    argued to the factfinder that Cronin was motivated to change her story and first
    implicated Guzman in November 1991 for the reward money. Further, Guzman’s
    counsel could have argued that the timing of the Detective Sylvester’s deposit of
    the reward money into Cronin’s inmate account, occurring just a few days before
    Cronin’s grand jury testimony, was an incentive for Cronin to testify favorably for
    the State against Guzman. Moreover, Guzman was denied a fair opportunity to
    impeach Cronin regarding not only the fact she was paid a reward, but the timing
    of the offer and payment of the reward, which could have supported an argument
    that Cronin’s changed statement and grand jury testimony were motivated by the
    reward.
    Third, although the Florida Supreme Court acknowledged that both Cronin
    and Detective Sylvester lied about the $500 reward during trial, the court either
    did not consider or unreasonably discounted the import of the fact that both
    Cronin and Sylvester testified falsely. Cf. Porter v. McCullom, 
    130 S. Ct. 447
    ,
    454 (2009) (finding the Florida Supreme Court’s decision, in the context of an
    ineffective assistance of counsel claim, was an unreasonable application of the
    31
    general Strickland standard, where the state court “either did not consider or
    unreasonably discounted the mitigation evidence adduced in the postconviction
    hearing”). In this regard, we agree with the dissent of Justice Anstead, when he
    stated:
    a rational and objective factfinder would not only have considered the
    fact that Cronin, the most important witness for the State, was paid for
    her testimony, but would also have considered the fact that both this
    crucial witness and the lead detective in the case perjured themselves
    when they denied under oath that any compensation was paid to Cronin.
    And, critically, it would have been of especial concern to the factfinder
    that this crucial State witness had previously and repeatedly denied any
    knowledge of the case and only implicated the defendant after the State
    offered compensation to her.
    Guzman, 
    941 So. 2d at 1056
     (Anstead, J., dissenting). While the state court
    considered the failure to disclose the $500 reward as to Cronin’s testimony,
    neither the trial court on remand, nor the Florida Supreme Court on review,
    addressed “the impact of the inability to impeach Detective Sylvester concerning
    her denial that any payment had been provided to Ms. Cronin.” Guzman, 
    698 F. Supp. 2d at 1332
    . Guzman’s “counsel was never given the opportunity to impeach
    the detective concerning her false testimony with regard to the payment, or to
    impeach her regarding her having permitted the key witness to give false
    testimony under oath before the court in the trial proceeding.” 
    Id.
    32
    The state courts’ decisions were objectively unreasonable because they all
    but ignored the importance of Detective Sylvester’s testimony and what defense
    counsel could have done with this impeachment evidence. In determining the
    impact of the State’s action in suppressing favorable evidence, courts should
    consider how the defense’s knowledge of the withheld information would have
    impacted not just the evidence presented at trial, but also the strategies, tactics,
    and defenses that the defense could have developed and presented to the trier of
    fact.20 Because Detective Sylvester was the lead detective, her impeachment
    would have “impugned not only her veracity but the character of the entire
    investigation.” Guzman, 
    698 F. Supp. 2d at 1332
    . This would have been
    consistent with Guzman’s testimony that he was not involved in the offense and
    evidence of other viable suspects.21

    21
    At Guzman’s trial both State and defense witnesses testified to facts which implicated
    persons other than Guzman in Colvin’s murder. For example, state witness James Yarborough,
    an employee of the Imperial Hotel, testified that he broke up an altercation between Colvin and
    33
    Detective Sylvester testified about the thoroughness of the state’s
    investigation, her contact with important witnesses in the case (including Rogers
    and Cronin), her search of Guzman’s jail cell,22 and her decision to focus the
    investigation exclusively on Guzman after Cronin implicated him in late
    November 1991. For example, during the first four months of investigating
    Colvin’s homicide—from August 12, 1991 when his body was discovered until
    late November 1991 when Cronin first implicated Guzman—Detective Sylvester
    testified that law-enforcement “continued to follow-up on any information that
    came in.” Further, during this time period, Detective Sylvester affirmed that the
    police had not “focused on Guzman as the sole suspect to the exclusion of
    another hotel guest named James (not Guzman) in Colvin’s hotel room. In that incident, James
    entered Colvin’s room with an open knife and Colvin pulled his sword. Detective Sylvester
    testified that she obtained information during her investigation that persons named Holt or Moore
    also had an altercation with Colvin in his hotel room in which a knife was involved. Detective
    Sylvester also testified on August 12, 1991, the date Colvin’s body was found and the police
    initiated their investigation, Curtis Wallace was at the Imperial Hotel. On that date, before the
    police released information that Colvin’s ring was missing, Wallace told the police that if a ring
    is missing, he probably knew who committed the crime.
    22
    Detective Sylvester testified that Rogers contacted her from the jail and indicated that
    he was Guzman’s cell mate and had information to provide against Guzman. After interviewing
    Rogers, Sylvester obtained and executed a search warrant for Guzman’s jail cell where she found
    amongst Guzman’s belongings a corner of an envelope containing Rogers’ mother’s return
    mailing address. This evidence later became important during Rogers’ testimony, in which he
    testified that Guzman confessed to him, to support his explanation for why he signed a sworn
    affidavit that Guzman never confessed to him—that Guzman knew where Rogers’ mother lived
    and could get to his family if he testified against him.
    34
    everyone else.” According to Detective Sylvester, she pursued “all leads” and
    interviewed “all possible witnesses” between early August and November 1991.
    But Detective Sylvester denied that she was “able to develop any
    substantive evidence against anyone that would give [her] cause to arrest anyone”
    before Cronin provided her statement against Guzman. This testimony from
    Detective Sylvester undermined Guzman’s alternate suspect theory of defense.
    For this reason, too, Detective Sylvester’s testimony and her credibility was
    important to the State’s case. Indeed, during the evidentiary hearing in the state
    habeas proceeding, Guzman’s trial attorney affirmed that he would have used the
    payment of $500 to Martha Cronin to impeach Detective Sylvester. Given these
    facts, the state court’s failure to consider the impact of the undisclosed evidence as
    to Detective Sylvester was objectively unreasonable.
    Our conclusion that the state court’s materiality determination was
    objectively unreasonable is buttressed by the fact that the state’s evidence
    connecting Guzman to the crime was circumstantial and far from overwhelming.
    There were no eyewitnesses or unbiased observers who testified as to the murder-
    robbery. Guzman never confessed to law-enforcement. Both witnesses who
    testified that Guzman had confessed, Cronin and Rogers, recanted their testimony
    at one time or another prior to trial. There was no blood or fingerprints on the
    35
    sword recovered from Colvin’s room. As previously noted, the medical examiner
    was uncertain about whether the sword or Guzman’s knife were the actual murder
    weapons; thus, the State did not prove that either Guzman’s knife or the sword
    was the murder weapon. As a result, Cronin’s and Detective Sylvester’s testimony
    was the crux of the State’s case again Guzman, and it was thus objectively
    unreasonable to discount the effect of bias on that crucial body of evidence under
    the totality of circumstances in this case.
    We also find it significant that Guzman not only testified on his own behalf
    at trial, but also presented witnesses and otherwise challenged the State’s
    evidence. For example, Guzman presented the testimony of Carmelo Garcia, who
    testified that Cronin had told him that she had lied to law enforcement regarding
    Guzman’s involvement because she wanted to avoid being arrested for an
    outstanding warrant. Moreover, these facts are relevant because the materiality
    test for Brady violations, of which Gilglio is an aggravated species, see Hammond,
    
    586 F.3d at
    1306–07, is not a sufficiency of the evidence test. See Kyles, 
    514 U.S. at 425
    , 
    115 S. Ct. at 1566
    ; see also, Smith, 
    572 F.3d at 1347
     (stating, in the
    context of a Brady materiality analysis, “the standard that is applied is not one of
    sufficiency of evidence to convict).” In Kyles, the Supreme Court explained:
    36
    A defendant need not demonstrate that after discounting the inculpatory
    evidence in light of the undisclosed evidence, there would not have been
    enough left to convict. The possibility of an acquittal on a criminal
    charge does not imply an insufficient evidentiary basis to convict. One
    does not show a Brady violation by demonstrating that some of the
    inculpatory evidence should have been excluded, but by showing that
    the favorable evidence could reasonably be taken to put the whole case
    in such a different light as to undermine confidence in the verdict.
    
    514 U.S. at
    434–35, 
    115 S. Ct. at 12566
    . Thus, even assuming the state court
    could have diminished the significance of Cronin’s testimony to oblivion (which it
    could not have reasonably done for the reasons described above), the fact that
    there may have been sufficient evidence to convict is not the relevant materiality
    question.
    Moreover, we have carefully reviewed the entire record, examined the state
    court’s arguments and theories in support of its decision, and afforded the state
    court every benefit of the doubt. Given all of these facts, we hold it was
    objectively unreasonable for the Florida Supreme Court to conclude that there was
    not any reasonable likelihood that the $500 reward and Cronin’s and Detective
    Sylvester’s perjury could not have affected the outcome in this case. We find
    “there is no possibility that fairminded jurists could disagree that the state court’s
    decision” was an unreasonable application of United States Supreme Court’s
    37
    precedents regarding the knowing presentation of false evidence. See Harrington,
    ---U.S. at ---, 131 S. Ct. at 786.
    Having found the state court’s decision was an unreasonable application of
    clearly established federal law, we further find that Guzman’s claim is meritorious
    for all the reasons discussed above. But this does not end our inquiry. We must
    next consider whether Guzman’s Giglio claim had a substantial and injurious
    effect on the outcome of his trial. See Brecht, 
    507 U.S. at
    637–38, 
    113 S. Ct. at
    1721–22 (directing habeas courts to determine whether constitutional errors at trial
    “had substantial and injurious effect or influence in determining the jury’s
    verdict”) (quoting Kotteakos v. United States, 
    328 U.S. 750
    , 776, 
    66 S. Ct. 1239
    ,
    1253 (1946)). Errors are harmless where there is significant corroborating
    evidence, Mason v. Allen, 
    605 F.3d 1114
    , 1121–24 (11th Cir. 2010); Grossman v.
    McDonough, 
    466 F.3d 1325
    , 1337–40 (11th Cir. 2006), or where evidence of guilt
    is overwhelming. Prevatte v. French, 
    547 F.3d 1300
    , 1305–1306 (11th Cir. 2008).
    Errors are harmful, however, when there are “significant weaknesses in the
    State’s case against the defendant.” 
    Id. at 1306
     (citation omitted). One such
    weakness is where the trial boils down to a swearing match between the
    petitioner’s and State’s witnesses. See Hill v. Turpin, 
    135 F.3d 1411
    , 1416–18
    (11th Cir. 1998). In the same vein, the petitioner is prejudiced when the State
    38
    procures its key witness by violating the petitioner’s rights. See Delguidice v.
    Singletary, 
    84 F.3d 1359
    , 1360–64 (11th Cir. 1996) (granting the writ where the
    State’s rebuttal witness, a psychiatrist, interviewed the defendant without adequate
    notice to defense counsel, and where that evidence was the State’s only evidence
    against the petitioner’s convincing insanity defense). As we have previously
    demonstrated, there were significant weaknesses in the State’s case against
    Guzman and the trial boiled down essentially a credibility contest between
    Guzman on the one side, and Cronin and Sylvester on the other side, but the State
    failed to correct materially false testimony of Cronin and Sylvester. After
    considering the entire record in this case, we cannot say with fair assurance that
    the outcome of Guzman’s trial was not swayed by the Giglio error. But even
    assuming, arguendo, the evidence was more evenly balanced regarding the
    harmlessness of the error, our “grave doubt” about the harmlessness of the error
    based upon the record compels us to rule in Guzman’s favor. See O’Neal v.
    McAninch, 
    513 U.S. 432
    , 435–37, 
    115 S. Ct. 992
    , 994–95 (1995). As a result,
    Guzman is entitled to a habeas relief, in this case a new trial, on his Giglio claim.
    39
    Therefore, we affirm the District Court’s Order granting Guzman a new trial on his
    Giglio claim.23
    AFFIRMED.
    23
    As noted earlier, we expressly decide Guzman’s case on his Giglio claim without
    expressing any opinion regarding the reasonableness of the state court’s decision with respect to
    his Brady claim.
