Lead Opinion
delivered the opinion of the Court.
The right to a fair trial, guaranteed to state criminal defendants by the Due Process Clause of the Fourteenth Amendment, imposes on States certain duties consistent with their sovereign obligation to ensure “that ‘justice shall be done’” in all criminal prosecutions. United States v. Agurs, 427 U. S. 97, 111 (1976) (quoting Berger v. United States, 295 U. S. 78, 88 (1935)). In Brady v. Maryland, 373 U. S. 83 (1963), we held that when a State suppresses evidence favorable to an accused that is material to guilt or to punishment, the State violates the defendant’s right to due process, “irrespective of the good faith or bad faith of the prosecution.” Id., at 87.
In this case, Gary Cone, a Vietnam veteran sentenced to death, contends that the State of Tennessee violated his right to due process by suppressing witness statements and police reports that would have corroborated his trial defense and bolstered his case in mitigation of the death penalty. At his trial in 1982, Cone asserted an insanity defense, contending that he had killed two people while suffering from acute amphetamine psychosis, a disorder caused by drug addiction. The State of Tennessee discredited that defense, alleging that Cone’s drug addiction was “ ‘baloney.’ ” 492 F. 3d 743, 760 (CA6 2007) (Merritt, J., dissenting). Ten years later, Cone learned that the State had suppressed evidence supporting his claim of drug addiction.
Cone presented his new evidence to the state courts in a petition for postconviction relief, but the Tennessee courts
After a complete review of the trial and postconviction proceedings, we conclude that the Tennessee courts’ rejection of petitioner’s Brady claim does not. rest on a ground that bars federal review. Furthermore, although the District Court and the Court of Appeals passed briefly on the merits of Cone’s claim, neither court distinguished the materiality of the suppressed evidence with respect to Cone’s guilt from the materiality of the evidence with respect to his punishment. While we agree that the withheld documents were not material to the question whether Cone committed murder with the requisite mental state, the lower courts failed to adequately consider whether that same evidence was material to Cone’s sentence. Therefore, we vacate the decision of the Court of Appeals and remand the case to the District Court to determine in the first instance whether there is a reasonable probability that the withheld evidence would have altered at least one juror’s assessment of the appropriate penalty for Cone’s crimes.
I
On the afternoon of Saturday, August 10, 1980, Cone robbed a jewelry store in downtown Memphis, Tennessee. Fleeing the scene by car, he led police on a high-speed chase
A short time later, Cone tried to hijack a nearby car. When that attempt failed (because the driver refused to surrender his keys), Cone tried to shoot the driver and a hovering police helicopter before realizing he had run out of ammunition. He then fled the scene. Although police conducted a thorough search, Cone was nowhere to be found.
Early the next morning, Cone reappeared in the same neighborhood at the door of an elderly woman. He asked to use her telephone, and when she refused, he drew a gun. Before he was able to gain entry, the woman slammed the door and called the police. By the time officers arrived, however, Cone had once again disappeared.
That afternoon, Cone gained entry to the home of 93-year-old Shipley Todd and his wife, 79-year-old Cleopatra Todd. Cone beat the couple to death with a blunt instrument and ransacked the first floor of their home. Later, he shaved his beard and escaped to the airport without being caught. Cone then traveled to Florida, where he was arrested several days later after robbing a drugstore in Pompano Beach.
A Tennessee grand jury charged Cone with two counts of first-degree murder, two counts of murder in the perpetration of a burglary, three counts of assault with intent to murder, and one count of robbery by use of deadly force. At his jury trial in 1982, Cone did not challenge the overwhelming physical and testimonial evidence supporting the charges against him. His sole defense was that he was not guilty by reason of insanity.
Two expert witnesses testified on Cone’s behalf. Matthew Jaremko, a clinical psychologist, testified that Cone suffered from substance abuse and posttraumatic stress disorders related to his military service in Vietnam. Jaremko testified that Cone had expressed remorse for the murders, and he opined that Cone’s mental disorder rendered him substantially incapable of conforming his conduct to the law. Jonathan Lipman, a neuropharmacologist, recounted at length Cone’s history of illicit drug use, which began after Cone joined the Army and escalated to the point where Cone was consuming “rather horrific” quantities of drugs daily. App. 100. According to Lipman, Cone’s drug abuse had led to chronic amphetamine psychosis, a disorder manifested through hallucinations and ongoing paranoia that prevented Cone from obeying the law and appreciating the wrongfulness of his actions.
In rebutting Cone’s insanity defense the State’s strategy throughout trial was to present Cone as a calculating, intelligent criminal who was fully in control of his decisions and actions at the time of the crimes. A key component of that
Particularly damaging to Cone’s defense was the testimony of rebuttal witness llene Blankman, who had spent time with Cone several months before the murders and at whose home Cone had stayed in the days leading up to his arrest in Florida. Blankman admitted to being a former heroin addict but testified that she no longer used drugs and tried to stay away from people who did. She testified that she had never seen Cone use drugs, had never observed track marks on his body, and had never seen him exhibit signs of paranoia.
Emphasizing the State’s position with respect to Cone’s alleged addiction, the prosecutor told the jury during closing argument, “[YJou’re not dealing with a crazy person, an insane man. A man . . . out of his mind. You’re dealing, I submit to you, with a premeditated, cool, deliberate — and even cowardly, really — murderer.” Tr. 2084 (Apr. 22, 1982). Pointing to the quantity of drugs found in Cone’s car, the prosecutor suggested that far from being a drug addict, Cone was actually a drug dealer. The prosecutor argued, “Pm not trying to be absurd, but he says he’s a drug addict. I say
The jury rejected Cone’s insanity defense and found him guilty on all counts. At the penalty hearing, the prosecution asked the jury to find that Cone’s crime met the criteria for four different statutory aggravating factors, any one of which would render him eligible for a capital sentence.
On direct appeal Cone raised numerous challenges to his conviction and sentence. Among those was a claim that the prosecution violated state law by failing to disclose a tape-recorded statement and police reports relating to several trial witnesses. See id., at 114-117. The Tennessee Supreme Court rejected each of Cone’s claims, and affirmed his conviction and sentence. State v. Cone, 665 S. W. 2d 87 (1984).
In 1989, Cone, acting pro se, filed a second petition for postconviction relief, raising myriad claims of error. Among these was a claim that the State had failed to disclose evidence in violation of his rights under the United States Con
Cone appealed the denial of his petition to the Tennessee Court of Criminal Appeals, asserting that the postconvietion court had erred by dismissing 13 claims — his Brady claim among them — as previously determined when, in fact, they had not been “previously addressed or determined by any court.” Brief for Petitioner-Appellant in No. P-06874, pp. 23-24, and n. 11. In addition Cone urged the court to remand the case to allow him, with the assistance of counsel, to rebut the presumption that he had waived any of his claims by not raising them at an earlier stage in the litigation. Id., at 24.
On remand counsel was appointed, and an amended petition was filed. The State once again urged the postconvic
While that petition remained pending before the postconvietion court, the Tennessee Court of Appeals held for the first time that the State’s Public Records Act allowed a criminal defendant to review the prosecutor’s file in his ease. See Capital Case Resource Center of Tenn., Inc. v. Woodall, No. 01-A-019104CH00150, 1992 WL 12217 (Jan. 29, 1992). Based on that holding, Cone obtained access to the prosecutor’s files, in which he found proof that evidence had indeed been withheld from him at trial. Among the undisclosed documents Cone discovered were statements from witnesses who had seen him several days before and several days after the murders. The witnesses described Cone’s appearance as “wild eyed,” App. 50, and his behavior as “real weird,” id., at 49. One witness affirmed that Cone had appeared “to be drunk or high.” Ibid. The file also contained a police report describing Cone’s arrest in Florida following the murders. In that report, a police officer described Cone looking around “in a frenzied manner,” and “walking in [an] agitated manner” prior to his apprehension. Id., at 53. Multiple police bulletins describing Cone as a “drug user” and a “heavy drug user” were also among the undisclosed evidence. See id., at 55-59.
With the newly discovered evidence in hand, Cone amended his postconviction petition once again in October 1993, expanding his Brady claim to allege more specifically that the State had withheld exculpatory evidence demonstrating that he “did in fact suffer drug problems and/or drug withdrawal or psychosis both at the time of the offense and in the past.” App. 20. Cone pointed to specific examples of evidence that had been withheld, alleging the evidence
After denying Cone’s request for an evidentiary hearing, the postconviction court denied relief on each claim presented in the amended petition. Many of the claims were dismissed on the ground that they had been waived by Cone’s failure to raise them in earlier proceedings; however, consistent with the position urged by the State, the court dismissed many others, including the Brady claim, as mere “re-statements of previous grounds heretofore determined and denied by the Tennessee Supreme Court upon Direct Appeal or the Court of Criminal Appeals upon the First Petition.” App. 22.
Noting that “the findings of the trial court in post-conviction hearings are conclusive on appeal unless the evidence preponderates against the judgment,” the Tennessee Court of Criminal Appeals affirmed. Cone v. State, 927 S. W. 2d 579, 581-582 (1995). The court concluded that Cone had “failed to rebut the presumption of waiver as to all claims raised in his second petition for post-conviction relief which had not been previously determined." Id., at 582 (emphasis added). Cone unsuccessfully petitioned for re
Ill
In 1997, Cone filed a petition for a federal writ of habeas corpus. Without disclosing to the District Court the contrary position it had taken in the state-court proceedings, the State acknowledged that Cone’s Brady claim had not been raised prior to the filing of his second postconviction petition. However, wrenching out of context the state appellate court’s holding that Cone had “waived ‘all claims ... which had not been previously determined,’ ” the State now asserted the Brady claim had been waived. App. 39 (quoting Cone, 927 S. W. 2d, at 582).
In May 1998, the District Court denied Cone’s request for an evidentiary hearing on his Brady claim. Lamenting that its consideration of Cone's claims had been “made more difficult” by the parties’ failure to articulate the state procedural rules under which each of Cone's claims had allegedly been defaulted, App. to Pet. for Cert. 98a, the District Court nevertheless held that the Brady claim was procedurally barred. After parsing the claim into 11 separate subclaims based on 11 pieces of withheld evidence identified in the habeas petition, the District Court concluded that Cone had waived each subclaim by failing to present or adequately develop it in state court. App. to Pet. for Cert. 112a-113a. Moreover, the court concluded that even if Cone had not defaulted his Brady claim, it would fail on its merits because none of the withheld evidence would have cast doubt on Cone’s guilt. App. to Pet. for Cert. 116a-119a. Throughout its opinion the District Court repeatedly referenced factual allegations contained in early versions of Cone’s second petition for post-conviction relief rather than the amended version of the petition upon which the state court’s decision had rested. See, e. g., id., at 112a.
The Court of Appeals concluded that Cone had proeedurally defaulted his Brady claim and had failed to show cause and prejudice to overcome the default. Cone v. Bell, 243 F. 3d 961, 968 (2001). The court acknowledged that Cone had raised his Brady claim. 243 F. 3d, at 969. Nevertheless, the court considered itself barred from reaching the merits of the claim because the Tennessee courts had concluded the claim was “previously determined or waived under Tenn. Code Ann. §40-30-112.” Ibid.
Briefly mentioning several isolated pieces of suppressed evidence, the court summarily concluded that even if Cone’s Brady claim had not been defaulted, the suppressed evidence would not undermine confidence in the verdict (and hence was not Brady material) “because of the overwhelming evidence of Cone’s guilt.” 243 F. 3d, at 968, 969. The court did not discuss whether any of the undisclosed evidence was material with respect to Cone’s sentencing proceedings.
In 2004, following our remand, the Court of Appeals again entered judgment ordering a new sentencing hearing, this time based on the purported invalidity of an aggravating circumstance found by the jury. Cone v. Bell, 359 F. 3d 785. Again we granted certiorari and reversed, relying in part on the deferential standard that governs our review of state-court decisions under AEDPA. See Bell v. Cone, 543 U. S. 447, 452-458 (2005) (per curiam).
Following our second remand, the Court of Appeals revisited Cone’s Brady claim. This time, the court divided the claim into four separate subclaims: “(1) evidence regarding [Cone’s] drug use; (2) evidence that might have been useful to impeach the testimony and credibility of prosecution witness Sergeant Ralph Roby; (3) FBI reports;
Judge Merritt dissented. He castigated the State not only for withholding documents relevant to Cone’s sole defense and plea for mitigation, but also for its “falsification of the procedural record ... concerning the State’s procedural default defense to the Brady claim.” Id., at 760. Over the dissent of seven judges, Cone’s petition for rehearing en banc was denied. 505 F. 3d 610 (2007).
We granted certiorari to answer the question whether a federal habeas claim is “ ‘procedurally defaulted’ ” when it is twice presented to the state courts. Pet. for Cert. i.
IV
During the state and federal proceedings below, the State of Tennessee offered two different justifications for denying review of the merits of Cone’s Brady claim. First, in connection with Cone’s amended petition for state postconviction relief, the State argued that the Brady claim was barred because it had been decided on direct appeal. See App. 15-16. Then, in connection with Cone’s federal habeas petition, the State argued that Cone’s claim was waived because it had never been properly raised before the state courts. See id,., at 39. The District Court and the Court of Appeals agreed that Cone’s claim was procedurally barred, but for different reasons. The District Court held that the claim
It is well established that federal courts will not review questions of federal law presented in a habeas petition when the state court’s decision rests upon a state-law ground that “is independent of the federal question and adequate to support the judgment.” Coleman v. Thompson, 501 U. S. 722, 729 (1991); Lee v. Kemna, 534 U. S. 362, 375 (2002). In the context of federal habeas proceedings, the independent and adequate state ground doctrine is designed to “ensur[e] that the States’ interest in correcting their own mistakes is respected in all federal habeas cases.” Coleman, 501 U. S., at 732. When a petitioner fails to properly raise his federal claims in state court, he deprives the State of “an opportunity to address those claims in the first instance” and frustrates the State’s ability to honor his constitutional rights. Id., at 732,748. Therefore, consistent with the longstanding requirement that habeas petitioners must exhaust available state remedies before seeking relief in federal court, we have held that when a petitioner fails to raise his federal claims in compliance with relevant state procedural rules, the state court’s refusal to adjudicate the claim ordinarily qualifies as an independent and adequate state ground for denying federal review. See id., at 731.
That does not mean, however, that federal habeas review is barred every time a state court invokes a procedural rule to limit its review of a state prisoner’s claims. We have recognized that “ ‘[t]he adequacy of state procedural bars to the assertion of federal questions’ ... is not within the State’s prerogative finally to decide; rather, adequacy ‘is itself a federal question.’” Lee, 534 U. S., at 375 (quoting Douglas v.
First, we address the contention that the repeated presentation of a claim in state court bars later federal review. The Tennessee postconviction court denied Cone’s Brady claim after concluding it had been previously determined following a full and fair hearing in state court. See Tenn. Code Ann. §40-30-112(a). That conclusion rested on a false premise: Contrary to the state courts’ finding, Cone had not presented his Brady claim in earlier proceedings, and, consequently, the state courts had not passed on it. The Sixth Circuit recognized that Cone’s Brady claim had not been decided on direct appeal, see Cone, 243 F. 3d, at 969, but felt constrained by the state courts’ refusal to reach the merits of that claim on postconviction review. The Court of Appeals concluded that because the state postconviction courts had applied a state procedural law to avoid reaching the merits of Cone’s Brady claim, “an ‘independent and adequate' state ground” barred federal habeas review. 243 F. 3d, at 969. In this Court the State does not defend that aspect of the Court of Appeals’ holding, and rightly so.
When a state court declines to review the merits of a petitioner’s claim on the ground that it has done so already, it creates no bar to federal habeas review. In Ylst v. Nunnemaker, 501 U. S. 797, 804, n. 3 (1991), we observed in passing that when a state court declines to revisit a claim it has already adjudicated, the effect of the later decision upon the availability of federal habeas is “nil” because “a later state decision based upon ineligibility for further state review neither rests upon procedural default nor lifts a pre-existing
A claim is procedurally barred when it has not been fairly presented to the state courts for their initial consideration— not when the claim has been presented more than once. Accordingly, insofar as the Court of Appeals rejected Cone’s Brady claim as procedurally defaulted because the claim had been twice presented to the Tennessee courts, its decision was erroneous.
As an alternative (and contradictory) ground for barring review of Cone’s Brady claim, the State has argued that Cone’s claim was properly dismissed by the state postconviction court on the ground it had been waived. We are hot persuaded. The state appellate court affirmed the denial of Cone’s Brady claim on the same mistaken ground offered by the lower court — that the claim had been previously determined.
When a state court declines to find that a claim has been waived by a petitioner’s alleged failure to comply with state procedural rules, our respect for the state-court judgment counsels us to do the same. Although we have an independent duty to scrutinize the application of state rules that bar our review of federal claims, Lee, 584 U. S., at 375, we have no concomitant duty to apply state procedural bars where
The State’s procedural objections to federal review of the merits of Cone’s claim have resulted in a significant delay in bringing this unusually protracted case to a conclusion. Ultimately, however, they provide no obstacle to judicial review. Cone properly preserved and exhausted his Brady claim in the state court; therefore, it is not defaulted. We turn now to the merits of that claim.
V
Although the State is obliged to “prosecute with earnestness and vigor,” it “is as much [its] duty to refrain from improper methods calculated to produce a wrongful conviction as it is to use every legitimate means to bring about a just one.” Berger, 295 U. S., at 88. Accordingly, we have held that when the State withholds from a criminal defendant evidence that is material to his guilt or punishment, it violates his right to due process of law in violation of the Fourteenth Amendment. See Brady, 373 U. S., at 87. In United States v. Bagley, 473 U. S. 667, 682 (1985) (opinion of Blackmun, J.), we explained that evidence is “material” within the meaning
The documents suppressed by the State vary in kind, but they share a common feature: Each strengthens the inference that Cone was impaired by his use of drugs around the time his crimes were committed. The suppressed evidence includes statements by witnesses acknowledging that Cone appeared to be “drunk or high,” App. 49, “acted real weird,” ibid., and “looked wild eyed,” id., at 50, in the two days preceding the murders.
Contending that the Federal District Court and Court of Appeals adequately and correctly resolved the merits of that claim, the State urges us to affirm the Sixth Circuit’s denial of habeas relief. In assessing the materiality of the evidence suppressed by the State, the Court of Appeals suggested that two facts outweighed the potential force of the suppressed evidence. First, the evidence of Cone’s guilt was overwhelming. Second, the evidence of Cone’s drug use was cumulative because the jury had heard evidence of Cone’s alleged addiction from witnesses and from officers who interviewed Cone and recovered drugs from his vehicle.
As in Brady, the distinction between the materiality of the suppressed evidence with respect to guilt and punishment is significant in this case. During the guilt phase of Cone’s trial, the only dispute was whether Cone was “sane under the law,” Tr. 2040 (Apr. 22, 1982), as his counsel described the issue, or “criminally responsible” for his conduct, App. 110, as the prosecutor argued. Under Tennessee law, Cone could not be held criminally responsible for the murders if, “at the time of [his] conduct as a result of mental disease or defect he laek[ed] substantial capacity either to appreciate the wrongfulness of his conduct or to conform his conduct to the requirements of law.” Graham v. State, 547 S. W. 2d 531, 543 (Tenn. 1977). Although we take exception to the
Cone’s experts testified that his drug addiction and post-traumatic stress disorder originated during his service in Vietnam, more than 13 years before the Todds were murdered. During those years, despite Cone’s drug use and mental disorder, he managed to successfully complete his education, travel, and (when not incarcerated) function in civil society. The suppressed evidence may have strengthened the inference that Cone was on drugs or suffering from withdrawal at the time of the murders, but his behavior before, during, and after the crimes was inconsistent with the contention that he lacked substantial capacity either to appreciate the wrongfulness of his conduct or to conform his conduct to the requirements of law. See Graham, 547 S. W. 2d, at 543. The likelihood that the suppressed evidence would have affected the jury’s verdict on the issue of insanity is therefore remote. Accordingly, we conclude that the Sixth Circuit did not err by denying habeas relief on the ground that the suppressed evidence was immaterial to the jury’s finding of guilt.
The same cannot be said of the Court of Appeals’ summary treatment of Cone’s claim that the suppressed evidence influenced the jury’s sentencing recommendation. There is a critical difference between the high standard Cone was required to satisfy to establish insanity as a matter of Tennessee law and the far lesser standard that a defendant must satisfy to qualify evidence as mitigating in a penalty hearing in a capital case. See Bell, 535 U. S., at 712 (Stevens, J., dissenting) (“[T]here is a vast difference between insanity— which the defense utterly failed to prove — and the possible mitigating effect of drug addiction incurred as a result of
Neither the Court of Appeals nor the District Court fully considered whether the suppressed evidence might have persuaded one or more jurors that Cone’s drug addiction— especially if attributable to honorable service of his country in Vietnam — was sufficiently serious to justify a decision to imprison him for life rather than sentence him to death. Because the evidence suppressed at Cone’s trial may well have been material to the jury’s assessment of the proper punishment in this case, we conclude that a full review of the suppressed evidence and its effect is warranted.
In the 27 years since Gary Cone was convicted of murder and sentenced to death, no Tennessee court has reached the merits of his claim that state prosecutors withheld evidence that would have bolstered his defense and rebutted the State’s attempts to cast doubt on his alleged drug addiction. Today we hold that the Tennessee courts’ procedural rejection of Cone’s Brady claim does not bar federal habeas review of the merits of that claim. Although we conclude that the suppressed evidence was not material to Cone's conviction for first-degree murder, the lower courts erred in failing to assess the cumulative effect of the suppressed evidence with respect to Cone’s capital sentence. Accordingly, the judgment of the Court of Appeals is vacated, and the case is remanded to the District Court with instructions to give full consideration to the merits of Cone’s Brady claim.
It is so ordered.
From the abandoned vehicle, police recovered stolen jewelry, large quantities of illegal and prescription drugs, and approximately $2,400 in cash. Much of the cash was later connected to a grocery store robbery that had occurred on the previous day.
The State also cast doubt on Cone’s defense by eliciting testimony that Cone had enrolled in college following his return from Vietnam and had graduated with high honors. Later, after serving time in prison for an armed robbery, Cone gained admission to the University of Arkansas Law School. The State suggested that Cone's academic success provided further proof that he was not impaired following his return from war.
In his closing rebuttal argument, the prosecutor continued to press the point, asserting; “There aren’t any charges for drug sales, but that doesn’t mean that you can’t look and question in deciding whether or not this man was, in fact, a drug user, or why he had those drugs. Did he just have those drugs, or did he have those drugs and thousands of dollars in that car? Among those drugs are there only the drugs he used? How do we know if he used drugs? The only thing that we ever had that he used drugs, period, is the fact that those drugs were in the car and what he told people. What he told people. But according to even what he told people, there are drugs in there he didn’t even use.” Tr. 2068 (Apr. 22, 1982).
The jury could impose a capital sentence only if it unanimously determined that one or more statutory aggravating circumstances had been proved by the State beyond a reasonable doubt, and that the mitigating circumstances of the case did not outweigh any statutory aggravating factors. Tenn. Code Ann. §39-2-203(g) (1982).
As defense counsel emphasized to the jury, one of the statutory mitigating factors it was required to consider was whether “[t]he capacity of the defendant to appreciate the wrongfulness of his conduct or to conform his conduct to the requirements of the law was substantially impaired as a result of mental disease or defect or intoxication which was insufficient to establish a defense to the crime but which substantially affected his judgment.” §39-2-203(j)(8).
Specifically, the jury found Cone had committed one or more prior felonies involving the use or threat of violence, see §39-2-203(i)(2); the mur
In summarizing the trial proceedings the Tennessee Supreme Court observed: “The only defense interposed on [Cone’s] behalf was that of insanity, or lack of mental capacity, due to drug abuse and to stress arising out of his previous service in the Vietnamese war, some eleven years prior to the events involved in this case. This proved to be a tenuous defense, at best, since neither of the expert witnesses who testified on his behalf had ever seen or heard of him until a few weeks prior to the trial. Neither was a medical doctor or psychiatrist, and neither had purported to treat him as a patient. Their testimony that he lacked mental capacity was based purely upon his personal recitation to them of his history of military service and drug abuse.” Id., at 90.
Under Tennessee law in effect at the time, a criminal defendant was entitled to collateral relief if his conviction or sentence violated “any right guaranteed by the constitution of [Tennessee] or the Constitution of the United States.” Tenn. Code Ann. §40-30-105 (1982); see also §40-30-102. Any hearing on a petition for postconvietion relief was limited, however, to claims that had not been “waived or previously determined.” See § 40-30-111. A ground for relief was “previously determined” if “a court of competent jurisdiction ha[d] ruled on the merits [of the claim] after a full and fair hearing.” §40-30-112(a). The claim was waived “if the petitioner knowingly and understanding^ failed to present it for determination in any proceeding before a court of competent jurisdiction in which the ground could have been presented.” § 40-30-112(b)(l).
See Swanson v. State, 749 S. W. 2d 731, 734 (Tenn. 1988) (courts should not dismiss postconvietion petitions on technical grounds unless the petitioner has first had “reasonable opportunity, with aid of counsel, to file amendments” and rebut presumption of waiver (internal quotation marks omitted)).
As examples of evidence that had been withheld, Cone pointed to “statements of Charles and Debbie Slaughter, statements of Sue Cone, statements of Lucille Tuech, statements of Herschel Dalton, and patrolman Collins” and “statements contained in official police reports.” App. 20.
11 In the course of federal habeas proceedings, Cone had obtained access to files from the Federal Bureau of Investigation where he found additional previously undisclosed evidence not contained in the state prosecutor’s case file. The suppressed FBI documents make repeated reference to Cone’s drug use and corroborate his expert’s representation that he had used drugs diming his prior incarceration for armed robbery. See App. 26-28.
With the exception of the Sixth Circuit, all Courts of Appeals to have directly confronted the question both before and after Ylst, 501 U. S. 797, have agreed that a state court’s successive rejection of a federal claim does not bar federal habeas review. See, e. g., Page v. Frank, 343 F. 3d 901, 907 (CA7 2003); Brecheen v. Reynolds, 41 F. 3d 1343, 1358 (CA10 1994); Bennett v. Whitley, 41 F. 3d 1581, 1582 (CA5 1994); Silverstein v. Henderson, 706 F. 2d 361, 368 (CA21983). See also Lambright v. Stewart, 241 F. 3d 1201, 1206 (CA9 2001).
As recounted earlier, Cone’s state postconviction petition contained numerous claims of error. The state postconviction court dismissed some of those claims as waived and others, including the Brady claim, as having been previously determined. In affirming the denial of Cone’s petition
Similarly, while Justice Alito’s parsing of the record persuades him that Cone failed to adequately raise his Brady claim to the Tennessee Court of Criminal Appeals, he does not argue that the court expressly held that Cone waived the claim. A review of Cone’s opening brief reveals that he made a broad challenge to the postconviction court’s dismissal of his petition and plainly asserted that the court erred by dismissing claims as previously determined on direct appeal or in his initial postconviction petition. See Brief for Petitioner-Appellant in No. 02-C-01-9408-CR-00052 (Term. Crim. App.), pp. 7, 14. The state appellate court did not state or suggest that Cone had waived his Brady claim. Rather, after commending the postconviction court for its “exemplary and meticulous treatment of the appellant’s petition,” Cone, 927 S. W. 2d, at 581, the appellate court simply adopted without modification the lower court’s findings with respect to the application of Tenn. Code Ann. §40-30-112 to the facts of this case. The best reading of the Tennessee Court of Criminal Appeals’ decision is that it was based on an approval of the postconviction court's reasoning rather than on an unmentioned failure by Cone to adequately challenge the dismissal of his Brady claim on appeal.
Setting aside the state courts’ mistaken belief that Cone’s Brady claim had been previously determined, there are many reasons the state courts might have rejected the State’s waiver argument. The record establishes that the suppressed documents which form the basis for Cone’s claim were not available to him until the Tennessee Court of Appeals’ 1992 decision interpreting the State’s Public Records Act as authorizing the disclosure of prosecutorial records. Soon after obtaining access to the prosecutor’s file and discovering within it documents that had not been disclosed prior to trial, Cone amended his petition for postconviction relief, adding detailed allegations regarding the suppressed evidence recovered from the file, along with an affidavit explaining the reason why his claim had not been filed sooner. See App. 13,18. The State did not oppose the amendment of Cone’s petition on the ground that it was untimely, and it appears undisputed that there would have been no basis under state law for doing so. See Brief for Petitioner 7, n. 1.
Although the Due Process Clause of the Fourteenth Amendment, as interpreted by Brady, only mandates the disclosure of material evidence, the obligation to disclose evidence favorable to the defense may arise more broadly under a prosecutor's ethical or statutory obligations. See Kyles, 514 U. S., at 437 (“[T]he rule in Bagley (and, hence, in Brady) requires less of the prosecution than the ABA Standards for Criminal Justice____ See . .. Prosecution Function and Defense Function 3-3.11(a) (3d ed. 1993)”). See also ABA Model Rule of Professional Conduct 3.8(d) (2008) (“The prosecutor in a criminal case shall” “make timely disclosure to the defense of all evidence or information known to the prosecutor that tends to negate the guilt of the accused or mitigates the offense, and, in connection with sentencing, disclose to the defense and to the tribunal all unprivileged mitigating information known to the prosecutor, except when the prosecutor is relieved of this responsibility by a protective order of the tribunal”). As we have often observed, the prudent prosecutor will err on the side of transparency, resolving doubtful questions in favor of disclosure. See Kyles, 514 U. S., at 439; United States v. Bagley, 473 U. S. 667, 711, n. 4 (1985) (Stevens, J., dissenting); United States v. Agurs, 427 U. S. 97, 108 (1976).
The State contends that the statements were made by witnesses who observed Cone during and immediately after he committed robberies; therefore, it is not surprising that Cone appeared less than “serene.” See
As the dissent points out, Roby did not testify directly that Cone was not a drug user, and FBI Agent Eugene Flynn testified that, at the time of Cone’s arrest in Pompano Beach, Cone reported that he had used cocaine, Dilaudid, and Demerol and was suffering from “‘slight withdrawal symptoms.’” See post, at 492-493, 496 (opinion of Thomas, J.). See also Tr. 1916,1920 (Apr. 22,1982). It is important to note, however, that neither Flynn nor Roby corroborated Cone’s account of alleged drug use. Taken in context, Roby’s statement that he had not observed any needle marks on Cone’s body invited the jury to infer that Cone’s self-reported drug use was either minimal or contrived. See id,., at 1939. Therefore, although the suppressed evidence does not directly contradict Roby’s trial testimony, it does place it in a different light.
In pointing to the trial evidence of Cone’s drug use, the Court of Appeals made no mention of the fact that the State had discredited the testimony of Cone’s experts on the ground that no independent evidence corroborated Cone’s alleged addiction and that the State had argued that the drugs in Cone’s car were intended for resale, rather than personal use.
We agree with the dissent that the standard to be applied by the District Court in evaluating the merits of Cone’s Brady claim on remand is whether there is a reasonable probability that, had the suppressed evidence been disclosed, the result of the proceeding would have been different. See post, at 491. Because neither the District Court nor the Court of Appeals considered the merits of Cone’s claim with respect to the effect of the withheld evidence on his sentence, it is appropriate for the District Court, rather than this Court, to do so in the first instance.
Concurrence Opinion
concurring in the judgment.
The Court’s decision is grounded in unusual facts that necessarily limit its reach. When issues under Brady v. Maryland, 373 U. S. 83 (1963), are presented on federal habeas, they usually have been previously addressed in state proceedings. Federal review is accordingly sharply limited by established principles of deference: If the claim has been waived under state rules, that waiver typically precludes federal review. If the claim has been decided in the state system, federal review is restricted in light of the state court’s legal and factual conclusions. The unique procedural posture of this case presents a Brady claim neither barred under state rules for failure to raise it nor decided in the state system.
When it comes to that claim, the Court specifies that the appropriate legal standard is the one we set forth in Kyles
That leaves only application of the accepted legal standard to the particular facts. It is highly unusual for this Court to engage in such an enterprise, see Kyles, supra, at 458 (Scalia, J., dissenting), and the Court’s asserted basis for doing so in this case is dubious, see post, at 486, 489-490 (Thomas, J., dissenting).
In any event, the Court’s review of the facts does not lead it to conclude that Cone is entitled to relief — only that the courts below did not adequately consider his claim with respect to sentencing. See ante, at 475 (“Neither the Court of Appeals nor the District Court fully considered whether the suppressed evidence” undermines confidence in Cone’s sentence). The Court simply reviews the facts in the light most favorable to Cone, concludes that the evidence does not undermine confidence in the jury’s determination that Cone is guilty, but sends the case back for “full consideration” of whether the same is true as to the jury’s sentence of death. Ante, at 474-476.
So this is what we are left with: a fact-specific determination, under the established legal standard, viewing the unique facts in favor of the defendant, that the Brady claim fails with respect to guilt, but might have merit as to sentencing. In light of all this,.I see no reason to quarrel with the Court’s ruling on the Brady claim.
In considering on remand whether the facts establish a Brady violation, it is clear that the lower courts should analyze the issue under the constitutional standards we have set forth, not under whatever standards the American Bar Association may have established. The ABA standards are
Concurrence in Part
concurring in part and dissenting in part.
We granted certiorari in this case to answer two questions:
“1. Is a federal habeas claim ‘procedurally defaulted’ because it has been presented twice to the state courts?
“2. Is a federal habeas court powerless to recognize that a state court erred in holding that state law precludes reviewing a claim?” Pet. for Cert. i.
Both of these questions are based on a factually incorrect premise, namely, that the Tennessee Court of Criminal Appeals, the highest state court to entertain petitioner’s appeal from the denial of his second petition for state postconviction relief,
But all of this is beside the point because the Tennessee Court of Criminal Appeals did not reject petitioner’s Brady claim on the ground that the claim had been previously determined on direct appeal. Rather, petitioner’s Brady claim was simply never raised before the Tennessee Court of Criminal Appeals, and that court did not rule on the claim at all.
Because the Sixth Circuit’s decision on the issue of procedural default rests on the same mistaken premise that the Tennessee Court of Criminal Appeals rejected petitioner’s Brady claim on the ground that it had been previously determined, I entirely agree with the majority that the Sixth Circuit’s decision on that issue cannot be sustained and that a remand is required. I cannot join the Court’s opinion, however, for two chief reasons.
First, the Court states without explanation that “Cone properly preserved and exhausted his Brady claim in the state court” and that therefore the claim has not been defaulted. Ante, at 469. Because Cone never fairly raised this claim in the Tennessee Court of Criminal Appeals, the claim is either not exhausted (if Cone could now raise the claim in state court) or is procedurally defaulted (if state law now provides no avenue for further review). I would leave these questions for resolution in the first instance on remand.
Second, the Court, again without explanation, remands this case to the District Court, not the Court of Appeals. I see no justification for this step.
I
In order to understand the tangled procedural default issue presented in this case, it is necessary to review the far-from-exemplary manner in which the attorneys for petitioner and respondent litigated the Brady claim in the state courts.
The first appearance of anything resembling the claim now at issue occurred in 1993 when petitioner’s experienced attorneys filed an amendment to his second petition for post-conviction relief in the Shelby County Criminal Court. This petition included a long litany of tangled claims. Paragraph 35 of this amended petition claimed, among other things, that the State had wrongfully withheld information demonstrating that one particular prosecution witness had testified falsely concerning “petitioner and his drug use.” App. 13-14. This nondisclosure, the petition stated, violated not only the Fifth and Fourteenth Amendments to the Constitution of the United States (which protect the due process right on which Brady is based) but also the Fourth, Sixth, and Eighth Amendments to the United States Constitution and four provisions of the Tennessee Constitution.
Two months later, counsel for petitioner filed an amendment adding 12 more claims, including one (¶ 41) alleging that the State had abridged petitioner’s rights by failing to disclose evidence that petitioner suffered from drug problems. App. 20. According to this new submission, the nondisclosure violated, in addition to the previously cited provisions of the Federal and State Constitutions, five more provisions of the State Constitution, including provisions regarding double jeopardy, see Tenn. Const., Art. I, § 10, ex post facto laws, § 11, indictment, § 14, and open courts, § 17.
The Shelby County Criminal Court was faced with the task of wading through the morass presented in the amended petition. Under Tenn. Code Ann. §40-30-112 (1990) (re
Given the importance now assigned to petitioner’s Brady claim, one might think that petitioner’s attorneys would have (1) stressed that claim in the opening brief that they filed in the Tennessee Court of Criminal Appeals, (2) pointed out the lower court’s clear error in concluding that this claim had been decided in the direct appeal, and (3) explained that information supporting the claim had only recently come to light due to the production of documents under the State’s Public Records Act. But counsel did none of these things. In fact, the Brady claim was not mentioned at all.
Nor was Brady cited in the reply brief filed by the same attorneys. The reply brief did contain a passing reference to “the withholding of exculpatory evidence,” but the brief did not elaborate on this claim and again failed to mention that this claim had never been previously decided and was supported by newly discovered evidence.
Appellate courts generally do not reach out to decide issues not raised by the appellant. Snell v. Tunnell, 920 F. 2d 673, 676 (CA10 1990); see Powers v. Hamilton Cty. Public Defender Comm’n, 501 F. 3d 592, 609-610 (CA6 2007); see also Galvan v. Alaska Dept. of Corrections, 397 F. 3d 1198, 1204 (CA9 2005) (“Courts generally do not decide issues not raised by the parties. If they granted relief to petitioners on grounds not urged by petitioners, respondents would be deprived of a fair opportunity to respond, and the courts would be deprived of the benefit of briefing” (footnote omitted)). Nor do they generally consider issues first mentioned in a reply brief. Physicians Comm. for Responsible Medicine v. Johnson, 436 F. 3d 326, 331, n. 6 (CA2 2006); Doe v. Beaumont Independent School Dist., 173 F. 3d 274, 299, n. 13 (CA5 1999) (Garza, J., dissenting); Doolin Security Sav. Bank, F. S. B. v. Office of Thrift Supervision, 156 F. 3d 190, 191 (CADC 1998) (per curiam); Boone v. Carlsbad Bancorporation, Inc., 972 F. 2d 1545, 1554, n. 6 (CA10 1992). And it is common practice for appellate courts to refuse to consider issues that are mentioned only in passing. Reynolds v. Wagner, 128 F. 3d 166, 178 (CA3 1997) (citing authorities).
The Tennessee Court of Criminal Appeals follows these standard practices. Rule 10(b) (2008) of that court states
In the decision now under review, the Sixth Circuit held that “[t]he Tennessee courts found that Cone’s Brady claims were 'previously determined’ and, therefore, not cognizable in [his] state post-conviction action.” 492 F. 3d 743, 756 (2007). In my judgment, however, there is no basis for concluding that the Tennessee Court of Criminal Appeals thought that any Brady issue was before it. A contrary in
The Sixth Circuit’s decision on the question of procedural default rests on an erroneous premise and must therefore be vacated.
II
I also agree with the Court that we should not affirm the decision below on the ground that the Brady claim lacks substantive merit. After its erroneous discussion of procedural default, the Sixth Circuit went on to discuss the merits of petitioner’s Brady claim. In its 2001 opinion, the Court of Appeals recognized that the prosecution’s Brady obligation extends not only to evidence that is material to guilt but also to evidence that is material to punishment. See Cone v. Bell, 243 F. 3d 961, 968 (citing Pennsylvania v. Ritchie, 480 U. S. 39, 57 (1987)). But neither in that opinion nor in its 2006 opinion did the court address the materiality of the information in question here in relation to petitioner’s punishment. See 492 F. 3d, at 756 (“A review of the allegedly withheld documents shows that this evidence would not have overcome the overwhelming evidence of Cone’s guilt in committing a brutal double murder and the persuasive testimony that Cone was not under the influence of drugs” (emphasis added)). Therefore, despite the strength of the arguments
Ill
The Court, however, does not simply vacate and remand to the Sixth Circuit but goes further.
First, the Court states without elaboration that petitioner “preserved and exhausted his Brady claim in the state court.” Ante, at 469. As I have explained, petitioner did not fairly present his Brady claim in his prior appeal to the Tennessee Court of Criminal Appeals, and therefore that claim is either unexhausted or procedurally barred. If the State is not now foreclosed from relying on the failure to exhaust, see 28 U. S. C. § 2254(b)(3), or on procedural default,
Second, the Court remands the case to the District Court rather than the Court of Appeals. A remand to the District Court would of course be necessary if petitioner were entitled to an evidentiary hearing, but the Court does not hold that an evidentiary hearing is either required or permitted. In my view, unless there is to be an evidentiary hearing, there is no reason to remand this case to the District Court. If the only purpose of remand is to require an evaluation of petitioner’s Brady claim in light of the present record, the District Court is not in a superior position to conduct such a
* * *
For these reasons, I would vacate the decision of the Court of Appeals and remand to that court.
The Court affirms Gary Cone’s conviction for beating an elderly couple to death with a blunt object. In so doing, the majority correctly rejects Cone’s argument that his guilty verdict was secured in violation of his rights under Brady v. Maryland, 373 U. S. 83 (1963). The majority declines, however, to decide whether the same evidence that was insufficient under Brady to overturn his conviction provides a basis for overturning his death sentence. The majority instead remands this question to the District Court for farther consideration because it finds that the Court of Appeals engaged in a “summary treatment” of Cone’s Brady sentencing claim. See ante, at 474-475.
I respectfully dissent. The Court of Appeals’ allegedly “summary treatment” of Cone’s sentencing claim does not justify a remand to the District Court. Cone has failed to establish “‘a reasonable probability that, had the evidence been disclosed to the defense, the result of the [sentencing]
I
This case arises from a crime spree 29 years ago that began with Cone’s robbery of a jewelry store in Memphis, Tennessee, and concluded with his robbery of a drugstore in Pompano Beach, Florida. Along the way, Cone shot a police officer and a bystander while trying to escape the first robbery, attempted to shoot another man in a failed carjacking attempt, unsuccessfully tried to force his way into a woman’s apartment at gunpoint, and murdered 93-year-old Shipley Todd and his 79-year-old wife, Cleopatra. When he was tried on two counts of first-degree murder in 1982, Cone’s sole defense was that he did not have the requisite intent to commit first-degree murder because he was in the grip of a chronic amphetamine psychosis. The jury rejected the defense and convicted Cone of both murders.
At sentencing, the Tennessee jury found beyond a reasonable doubt that four statutory aggravating factors applied to Cone’s offense: (1) Cone had been convicted of one or more previous felonies involving the use or threat of violence; (2) he had knowingly created a great risk of death to two or more persons other than the victim during his act of murder; (3) the murder was especially heinous, atrocious, or cruel in that it involved torture or depravity of mind; and (4) the murder was committed for the purpose of avoiding a lawful arrest. Tr. 2151-2152 (Apr. 23,1982); see also State v. Cone,
For almost three decades, Cone’s case has traveled through the Tennessee and federal courts. This Court has twice reversed decisions from the Court of Appeals that invalidated Cone’s conviction and sentence. See Bell v. Cone, 535 U. S. 685 (2002); Bell v. Cone, 543 U. S. 447 (2005) (per curiam). On remand from this Court’s latest decision, the Court of Appeals directly considered whether a handful of police reports, law enforcement bulletins, and notes that were allegedly withheld from Cone’s trial attorneys could have changed the result of Cone’s trial or sentencing. And, for the second time, the Court of Appeals held that there was not a “ ‘reasonable probability’ ” that the evidence would have altered the jury’s conclusion “that Cone’s prior drug use did not vitiate his specific intent to murder his victims and did not mitigate his culpability sufficient to avoid the death sentence.” 492 F. 3d 743, 757 (CA6 2007). The Court of Appeals, therefore, held that neither Cone’s conviction nor

According to the majority, the Court of Appeals’ decision affirming Cone’s death sentence is too “summary,” ante, at 474, and the facts are such that, on further examination, Cone “might” be able to demonstrate that it is “possible” that the contested evidence would have persuaded the jury to spare his life, ante, at 475. On this reasoning, the majority remands the case directly to the District Court for “full consideration [of] the merits of Cone’s [sentencing] claim.” Ante, at 476. I disagree on all counts. Remanding the sentencing issue to the District Court is an “unusual step” for this Court to take. House v. Bell, 547 U. S. 518, 557 (2006) (Roberts, C. J., concurring in judgment in part and dissenting in part). Furthermore, in this case, it is a step that is legally and factually unjustified. There is not “ ‘a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different.’” Kyles, 514 U. S., at 433-434 (quoting Bagley, 473 U. S., at 682 (opinion of Blackmun, J.)).
A
The majority’s criticism of the Court of Appeals’ allegedly “summary treatment” of the sentencing question is misplaced. Before the Court of Appeals, Cone dedicated eight pages of his opening brief to arguing that the implicated evidence was material to his guilt or innocence, but spent only one paragraph arguing its materiality to his death sentence. See Brief for Appellant in No. 99-5279 (CA6), pp. 40-48. The Court of Appeals’ focus on the guilt phase, rather than the sentencing phase, simply followed Cone’s lead. See 492 F. 3d, at 755 (“In his most recent brief, claiming that his

In remanding this matter to the District Court, the majority makes two critical errors — one legal and one factual— that leave the false impression that Cone’s Brady claim has a chance of success. First, the majority states that “[i]t is possible that the suppressed evidence” may have convinced the jury that Cone’s substance abuse played a mitigating role in his crime and “[tjhe evidence might also have rebutted the State’s suggestion” that Cone’s experts were inaccurately depicting the depth of his drug-induced impairment. Ante, at 475 (emphasis added); see also ibid, (remanding “[bjecause the evidence suppressed at Cone’s trial may well have been material to the jury’s assessment of the proper punishment in this case” (emphasis added)). But, as the majority implic
Rather, this Court has made clear that the legal standard for adjudicating such a claim is whether there is a “reasonable probability” that the jury would have been persuaded by the allegedly withheld evidence. Kyles, supra, at 435; Bagley, supra, at 682 (opinion of Blaekmun, J.). It simply is not sufficient, therefore, to claim that “there is a reasonable possibility that... testimony might have produced a different result.... [Petitioner's burden is to establish a reasonable probability of a different result.” Strickler v. Greene, 527 U. S. 263, 291 (1999) (emphasis in original). To satisfy the “reasonable probability” standard, Cone must show that “the favorable evidence could reasonably be taken to put the whole case in such a different light as to undermine confidence” in the jury’s sentencing determination. Kyles, supra, at 435. The Court must view the record “as a whole,” Sawyer v. Whitley, 505 U. S. 333, 374 (1992) (Stevens, J., concurring in judgment), and determine whether the absence of the disclosure prevented Cone from receiving “‘a trial resulting in a [sentence] worthy of confidence,’” Strickler, supra, at 290 (quoting Kyles, 514 U. S., at 434).
In the context of this case, for Cone to establish “ ‘a reasonable probability that, had the evidence been disclosed to the defense, the result of the [sentencing] proceeding would have been different,’ ” id., at 435, he must not only demonstrate that the withheld evidence would have established that he was substantially impaired as a result of drug abuse or withdrawal; Cone also must establish that the addition of the allegedly withheld evidence ultimately would have led
Second, the majority incorrectly claims that to prevail on his Brady claim, Cone must demonstrate simply that the withheld evidence supported the inference that he “was impaired by his use of drugs around the time his crimes were committed.” See ante, at 470. This is factually inaccurate because there was already significant evidence of Cone’s drug use at trial. To establish that the allegedly withheld evidence would reasonably have had any impact on his case, Cone must instead show that the evidence would have supported his claim of substantial mental impairment from drug use.
There was extensive evidence at trial that supported the inference that Cone was not only a longstanding drug user, but that he was in fact using drugs at the time of his crimes. The State itself presented significant evidence on this point. For example, it presented proof that officers found marijuana cigarette butts, empty drug vials, and loose syringes in the car that Cone abandoned immediately after the jewelry store robbery. Tr. 1505-1509 (Apr. 19,1982). The State also did not challenge testimony from Cone’s mother that Cone used drugs. Id., at 1647, 1648-1653 (Apr. 20, 1982). And, most tellingly, the State introduced evidence that Cone was abusing three drugs — cocaine, Dilaudid, and Demerol — at the time of his arrest and was suffering “slight withdrawal
In contrast, what was contested by the State during trial was Cone’s defense that his drug use was so significant that it caused him to suffer from extreme amphetamine psychosis at the time of the murders. One of Cone’s expert witnesses, a neuropharmacologist, testified that by the summer of 1980, when the crimes occurred, Cone was ingesting “ferociously large doses” of drugs and that his increasing tolerance and use of amphetamines caused a chronic amphetamine psychosis. Tr. 1736-1737, 1744-1747, 1758-1759 (Apr. 21, 1982). The expert further testified that if a person with chronic amphetamine psychosis were to go into withdrawal, he could suffer extreme mood swings, “a crashing depression,” and a state of weakness so severe that “he could barely lift himself.” Id., at 1857-1859. In this expert’s view, these symptoms could cause a person to “lose his mind.” Id., at 1859.
The State contradicted that testimony with significant evidence that Cone did not act like someone who was “out of his mind” during the commission of his crimes. Rather, the State argued, Cone behaved rationally during his initial Ten
Viewing the record as a whole, then, it is apparent that the contested issue at trial and sentencing was not whether Cone used drugs, but rather the quantity of Cone’s drug use and its effect on his mental state. Only if the evidence allegedly withheld from Cone was relevant to this question whether Cone suffered from extreme amphetamine psychosis or other substantial impairment would the evidence have been exculpatory for purposes of Brady. See Order Denying Motion for Evidentiary Hearing and Order of Partial Dismissal, Cone v. Bell, No. 97-2312-M1/A (WD Tenn., May 15, 1998), App. to Pet. for Cert. 119a, n. 9 (explaining that “the issue at trial was not whether Cone had ever abused any drugs (he clearly had), but whether he was out of his mind on amphetamines at the time of the murders”); Tr. 2115-2116 (Apr. 23, 1982).
Ill
With the legal and factual issues correctly framed, it becomes clear that Cone cannot establish a reasonable probability that admission of the evidence — viewed either individually or cumulatively — would have caused the jury to alter his sentence.
1
Cone first argues that he was improperly denied police reports that included witness statements regarding Cone’s behavior around the time of his crime spree. The first statement was given by a convenience store employee, Robert McKinney, who saw Cone the day before he robbed the Tennessee jewelry store. When asked whether Cone appeared “to be drunk or high on anything,” McKinney answered, “[w]ell he did, he acted real weird ... he just wandered around the store.” App. 49. But McKinney subsequently clarified that Cone “didn’t sound drunk” and that the reason Cone attracted his attention was because he “wasn’t acting like a regular customer”; he was “just kinda... wandering” around the store. Motion to Expand the Record, etc., in No. 97-2312-MI (WD Tenn.), Exh. 2, pp. 3, 4. Contrary to the majority’s assertion, this interview is not convincing evidence “that Cone appeared to be ‘drunk or high’ ” when McKinney saw him. Ante, at 470. McKinney’s clarification that he had characterized Cone’s behavior as “weird” because Cone appeared to be killing time rather than acting like a normal shopper undermines the implication of McKinney’s earlier statement that Cone looked “weird” because he might have been drunk or on drugs. Thus, there is little chance that McKinney’s statement would have provided any significant additional evidence that Cone was using drugs, let alone provide sentence-changing evidence that he was substantially impaired due to amphetamine psychosis.
The second statement was given by Charles and Debbie Slaughter, who both witnessed Cone fleeing from police after the jewelry store robbery and reportedly told police that he looked “wild eyed.” App. 50. Cone had just robbed a jewelry store, shot a police officer and a bystander, and was still fleeing from police when seen by the Slaughters. It is thus unlikely that their observation of a “wild eyed” man would
The third statement is contained in a police report authored by an officer who helped apprehend Cone after the Florida drugstore robbery. He reported that he saw a suspect “at the rear of Sambos Restaurant. Subject was observed to be looking about in a frenzied manner and also appeared to be looking for a place to run.” App. 53. Nothing in this police report either connects Cone to drug use or appears otherwise capable of altering the jury’s understanding of Cone’s mental state at the time of the crimes. It certainly makes perfect sense that Cone was “looking about in a frenzied manner,” ibid.; he had just robbed a drugstore and was about to engage in a gun battle with police in order to evade arrest. The police officer’s description of Cone’s appearance under these circumstances thus does not “undermine confidence” in Cone’s sentence. Kyles, 514 U. S., at 435.
2
The next category of documents that Cone relies upon to establish his Brady claim are police bulletins. Some of the bulletins were sent by Memphis Police Sergeant Roby to neighboring jurisdictions on the day of the Todd murders and the day after. The bulletins sought Cone’s apprehension and alternatively described him as a “drug user” or a “heavy drug user.” App. 55-58. Cone asserts that he could have used these bulletins to impeach Sergeant Roby’s trial testimony that the sergeant did not see any track marks when visiting Cone in jail a week later. Tr. 1939 (Apr. 22, 1982). Cone’s reasoning is faulty for two key reasons. First, Sergeant Roby never testified that Cone was not a drug user. His only trial testimony on this point was simply that he observed no “needle marks” on Cone’s arm when taking hair samples from him a few days after Cone’s apprehen
3
Cone also argues that material was withheld that could have been used to impeach llene Blankman’s testimony that Cone did not appear to be high or in withdrawal when she helped him obtain a Florida driver’s license during his efforts to evade arrest in Florida. Tr. 1875-1882 (Apr. 21, 1982). But he again fails to meet the standard for exculpatory evidence set by Brady.
Cone first points to police notes of a pretrial interview with Blankman, which did not reflect the statement she gave at trial that she saw no track marks on Cone’s arm. App. 72-73. But Blankman was questioned at trial about her failure to initially disclose this fact to police, Tr. 1903 (Apr. 21, 1982), so the jury was fully aware of the omission. Disclosure of the original copy of the police notes thus could not have had any material effect on the jury’s deliberations. Moreover, the missing notes also recorded a damning statement by Blankman that Cone “never used drugs around” her and she “never saw Cone with drug paraphernalia.” App.
Cone next relies on a report that describes a woman’s confrontation with the prosecution team and Blankman at a restaurant during trial. During the encounter, the woman accused Blankman of lying on the stand in order to frame Cone for the murders. Id., at 74-75. The report indicates that the prosecutors politely declined the woman’s numerous attempts to discuss the merits of the case and that Blankman said nothing. Id., at 75. Nothing about this encounter raises doubts about Blankman’s credibility.
Last, Cone points to “correspondence in the district attorney’s files suggesting] that the prosecution had been unusually solicitous of [Blankman’s] testimony.” Brief for Petitioner 45. But the correspondence was completely innocuous. One of the notes, sent in response to Blankman’s request for a copy of her prior statement, expressed to Blankman that her “cooperation in this particular matter is appreciated.” App. 76. The prosecutor then sent a letter to confirm that Blankman would testify at trial. Id., at 77. And finally, after trial, the prosecutor sent a note to inform Blankman of the verdict and indicate that they “certainly appreciated] [her] cooperation with [them] in the trial of Gary Bradford Cone.” Id., at 78. There is nothing about these notes that “tend[s] to prove any fact that is both favorable to Cone and material to his guilt or punishment.” App. to Pet. for Cert. 116a.
B
Viewing the record as a whole, Cone has not come close to demonstrating that there is a “reasonable probability” that the withheld evidence, analyzed individually or cumulatively, would have changed the result of his sentencing. Much of the impeachment evidence identified by Cone is of no probative value whatsoever. The police bulletins do not contra-
Countering the trivial value of the alleged Brady material is the clear and overwhelming evidence that during Cone’s crime spree, he was neither sufficiently insane to avoid a conviction of murder nor substantially impaired by his drug use or withdrawal-related psychosis. There was substantial evidence that Cone carefully planned the jewelry store robbery and was calm in carrying it out, Tr. 974-976, 1014 (Apr. 16, 1982), 1350-1352 (Apr. 17, 1982), 1501 (Apr. 19, 1982), 2075 (Apr. 22, 1982); that he successfully eluded police after engaging them in a shootout, id., at 1053-1064 (Apr. 16, 1982); that, after hiding overnight, he concocted a ruse to try to gain illegal entry to a residence, id., at 1205-1208 (Apr. 17, 1982); that he murdered the Todds after they declined to cooperate with his efforts to further elude police, id., at 1681 (Apr. 20, 1982); that he took steps to change his appearance at the Todd residence and then successfully fled to Florida, id., at 1918-1919 (Apr. 22, 1982); that he arrived in Florida exhibiting no signs of drug use or severe withdrawal, id., at 1875-1882 (Apr. 21, 1982); that he obtained false identification in a further effort to avoid apprehension, id., at 1881-1882; and that he denied any memory lapses and described undergoing only minor drug withdrawal when police ar
And even if Cone could have presented this evidence to the jury at sentencing and established an entitlement to this mitigator, he still has not demonstrated a reasonable probability that it would have outweighed all of the aggravating factors supporting the jury’s death sentence. See id., at 2151-2154 (Apr. 23, 1982). In its decision on direct appeal, the Tennessee Supreme Court was well aware of the evidence regarding the “degree and extent of [Cone’s] drug abuse.” Cone, 665 S. W. 2d, at 90. As part of its required independent review of whether the mitigation evidence was sufficiently substantial to outweigh the aggravating factors, see Tenn. Code Ann. §39-2-205, the Tennessee court nevertheless concluded that the sentence was “not in any way disproportionate under all of the circumstances, including the brutal murders of two elderly defenseless persons by an escaping armed robber who had terrorized a residential neighborhood for twenty-four hours.” 665 S. W. 2d, at 95-96. None of Cone’s proffered evidence places that conclusion, made by both the jury and the Tennessee Supreme Court, “in such a different light as to undermine confidence” in Cone’s sentence. Kyles, 514 U. S., at 435; see also Strickler, 527 U. S., at 296.

This Court should not vacate and remand lower court decisions based on nothing more than the vague suspicion that error might be present, or because the court below could have been more clear. This is especially so where, as here, the record before the Court is adequate to evaluate Cone’s Brady claims with respect to both the guilt and sentencing phases of his trial. The Court’s willingness to return the sentencing issue to the District Court without any firm con
Because the Tennessee Supreme Court denied discretionary review of the Tennessee Court of Criminal Appeals decision affirming the denial of petitioner’s second amended petition for postconviction relief, we must look to the decision of the latter court to determine if the decision below was based on an adequate and independent state ground. See Baldwin v. Reese, 541 U. S. 27, 30-32 (2004); O’Sullivan v. Boerckel, 526 U. S. 838, 842-843 (1999).
Brady v. Maryland, 373 U. S. 83 (1963).
Tennessee law has since changed. Currently, the Tennessee Post-Conviction Procedure Act bars any second postconvietion petition, see Tenn. Code Ann. § 40-30-102 (2006), and permits the reopening of a petition only under limited circumstances, §40-30-117. These restrictions apply to any petition filed after the enactment of the Post-Conviction Procedure Act, even if the conviction occurred long before.
After referring to a long list of claims (not including any claim for the failure to disclose exculpatory evidence), the reply brief states:
“[I]t is clear that meritorious claims have been presented for adjudication. These claims have not been waived and a remand for a hearing is essential
In a footnote in his reply brief, petitioner stated that he was not waiving any claim presented in the court below and asked the appellate court to consider all those claims. See Reply Brief 3, n. 1. But the Tennessee Court of Criminal Appeals has specifically held that claims may not be raised on appeal in this manner. See Leonard v. State, No. M2006-00654-CCA-R3-PC, 2007 WL 1946662, *21-*22 (July 5, 2007).
Unlike exhaustion, procedural default may be waived if it is not raised as a defense. Banks v. Dretke, 540 U. S. 668, 705 (2004) (allowing for waiver of “procedural default” “based on the State’s litigation conduct” (citing Gray v. Netherlands 518 U. S. 152, 166 (1996))). Here, it appears that the State has consistently argued that petitioner’s Brady claim was procedurally defaulted, but the State’s supporting arguments have shifted. Whether the question of procedural default described in this opinion should be entertained under the particular circumstances here is an intensely fact-bound matter that should be left for the Sixth Circuit on remand.
Because I would affirm on the basis of the Court of Appeals’ alternative holding below, I do not reach the issues of procedural default resolved by the majority. See United States v. Atlantic Research Corp., 551 U. S. 128, 141, n. 8 (2007); Ayotte v. Planned Parenthood of Northern New Eng., 546 U. S. 320, 332 (2006); Ardestani v. INS, 502 U. S. 129, 139 (1991).
The Tennessee Supreme Court later concluded that the record in Cone’s case was doubtful as to evidence supporting the second factor given the lapse in time between the initial events of the escape and the Todd murders. Cone, 665 S. W. 2d, at 95. The court, however, determined that the existence of the other three factors rendered any possible error in this factor harmless beyond a reasonable doubt. Ibid.
The assertion by the majority, ante, at 475, n. 19, and Justice Auto, ante, at 484 (opinion concurring in part and dissenting in part), that the Court of Appeals did not address the merits of the sentencing issue at all is flatly wrong. See 492 F. 3d, at 757 (rejecting Cone’s Brady claim because the proffered evidence would not have altered the jury’s conclusion “that Cone’s prior drug use did not vitiate his specific intent to murder his victims and did not mitigate his culpability sufficient to avoid the death sentence” (emphasis added)).
The majority does not attempt to justify its remand by contending that it is necessary because the record is insufficient to decide the claim. Nor could it persuasively contend a remand is necessary so that the District Court can hold an evidentiary hearing. Such a hearing would shed no additional light on the trial proceedings or the relative impeachment value of the withheld documents. Cone himself agrees that “this Court should resolve the merits of [his] Brady claim.” Reply Brief for Petitioner 24; see also Brief for Respondent 26-27.
The majority asserts that the standard under Tennessee law for demonstrating mental defect or intoxication as a mitigating factor at sentencing is “far lesser” than the standard for demonstrating insanity in the guilt phase of a criminal trial. Ante, at 474. But the mitigating factor still requires a showing that Cone’s mental capacity was “substantially impaired” as a result of mental defect. Tenn. Code Ann. §39-2-203(j)(8). In any event, the only authority cited by the majority for its assertion that the standard is “far” lesser than that for insanity is Justice Stevens’ lone dissent in a prior appeal in this case. Ante, at 474-475.
Although there were two occasions during closing arguments where prosecutors intimated that Cone was not a drug user, see Tr. 2014-2015, 2068 (Apr. 22, 1982), the State’s argument otherwise consistently focused on the real issue in the case: that Cone was not so significantly affected by his drug use around the time of his crimes that he was “out of his mind” or “drug crazy” during the critical days of August 1980. See id., at 2023-2024,2071-2084. The majority’s focus on two brief excerpts from the State’s closing argument fails to faithfully view the record “as a whole” for purposes of a Brady analysis. See Sawyer v. Whitley, 505 U. S. 333, 374 (1992) (Stevens, J., concurring in judgment); see also Strickler v. Greene, 527 U. S. 263, 290-291 (1999) (finding no reasonable probability of a different result even when prosecutor’s closing argument relied on testimony that could have been impeached by withheld material).
Alert bulletins sent by the FBI similarly identified Cone as a “believed heavy drug user” or a “drug user.” App. 62-70. Cone argues that these bulletins could have been used to impeach FBI Agent Flynn’s testimony about Cone’s arrest in Florida. The bulletins would not have constituted material impeachment evidence, however, for the second reason identified above. In addition, the bulletins would not have contradicted any of FBI Agent Flynn’s testimony; he in fact stated at trial that Cone reported using three drugs and was undergoing mild drug withdrawal when he was captured in Florida. Tr. 1915-1916 (Apr. 22, 1982).
