OPINION OF THE COURT
I. Introduction
Wе have approached this case with the utmost seriousness. We are humbled by the fact that over a twenty-eight-year period of time, the case has progressed through courts of the Commonwealth of Pennsylvania and the U.S. District Court without James Lambert having been granted relief. We, nonetheless, must decide this case consistent with what we believe our obligation to be, while according the utmost respect to the standard of review that we are required to apply. Having done so, we now vacate the judgment of the District Court dated July 24, 2007, and remand this matter to the District Court, which is directed to conditionally grant the petition for a writ of habeas corpus. If, within 120 days of the date of this Opinion and Order, the Commonwealth fails to retry Mr. Lambert, he shall be released. 1
II. Procedural History
It is not an overstatement to say that the procedural history of this case is extensive in the extreme, as would be expected in a case that has spanned more than twenty-eight years. We have carefully examined the numеrous issues Lambert has raised over these many years and how the various courts have resolved those issues. We, however, decide this case on one issue, an issue under
Brady v. Maryland,
James Lambert and Bruce Reese were arrested and charged with murder, rob *129 bery, criminal conspiracy, and possession of an instrument of crime based on what the Commonwealth had been told by one Bernard Jackson, who subsequently testified for the Commonwealth in exchange for an open guilty plea to third-degree murder, robbery, conspiracy, and several unrelated crimes. On April 25,1984, Lambert was convicted by a jury of two counts of first-degree murder as well as the other crimes with which he was charged, and was sentenced to death. Reese was convicted of second-degree murder, and was sentenced to lifе imprisonment.
Lambert moved for a new trial and to vacate the judgment, motions which were denied. He appealed, and in a 3-2 decision with two Justices not participating, the Pennsylvania Supreme Court upheld his conviction and affirmed the sentence of death.
See Commonwealth v. Lambert,
In 2002, Lambert filed a petition for a writ of habeas corpus in the United States District Court for the Eastern District of Pennsylvania raising twenty-four claims of constitutional error, most of which were accompanied by related allegations of ineffective assistance of counsel.

The District Court did not conduct an evidentiary hearing and denied relief on all claims, but granted a certificate of appealability (“COA”) on one guilt-phase claim relating to the Commonwealth’s alleged discriminatory use of peremptory challenges at jury selection in violation of
Batson v. Kentucky,
We then expanded the COA to include the following issues: (1) whether the Commonwealth’s failure to disclose exculpatory evidence and misrepresentation of the bargain given to its key witness in exchange for his testimony violated
Brady,
(2) whether Lambert was denied his right to present a defense, call witnesses on his behalf, and confront the evidence against him when he was barred from introducing evidence that Jackson and Reese had a history of committing robberies together and without him; (3) whether Lambert was denied his right to due process and a fair trial when the trial court allowed a witness called by Reese to identify Lambert for the first time in court; (4) whether Lambert was denied his right to due process when the trial court refused to
*130
sever his trial from Reese’s trial; (5) whether the trial court misled the jury about the role of appellate review in violation of
Caldwell v. Mississippi
III. Jurisdiction and Standard of Review
The District Court had jurisdiction under 28 U.S.C. §§ 1331, 2241, and 2254. We have appellate jurisdiction under 28 U.S.C. §§ 1291 and 2253. We exercise plenary review over the decision of the District Court, as the Court did not hold an evidentiary hearing.
See Simmons v. Beard,
Under the Antiterrorism and Effective Death Penalty Act of 1996 (“AEDPA”), where, as here, a habeas petitioner’s claims were adjudicated on the merits in state court, our review is limited to determining whether the state court decision was contrary to or involved an unreasonable application of Supreme Court precedent or an unreasonable determination of the facts in light of the evidence presented in the state court. See 28 U.S.C. § 2254(d).
IV. Factual Background
At approximately 9:00 on the evening of September 23, 1982, the robbery of Prince’s Lounge went bad, and two patrons were shot to death. The Philadelphia Police Department commenced an investigation, but the perpetrators could not be identified, although two of the three barmaids working that night gave general descriptions of each of the two perpetrators. Not long after the murders, however, an anonymous tip was received by the Department identifying Bernard Jackson and “Touche” (later identified as Reese, Jackson’s brother-in-law) as the men in the bar that night. Each barmaid was subsequently presented, for the first time, with a photo array that included Jackson’s photo. Sarah Clark identified Jackson as the man who was standing at the top of the stairs in thе bar and ordered her to place the money in a bag just before she heard two gunshots from the rear of the bar, the shots that killed the two patrons. Marie Green was 85 to 90 percent sure that the man at the top of the stairs was Jackson. Janet Ryan, the third barmaid, was working at the rear of the bar and dropped down and ran to the ladies room when the shooter pointed a gun in her face.
Jackson, who by then was in custody on another charge, learned that he had been identified by at least one of the barmaids and told the police about the Prince’s Lounge robbery and that Reese and “another dude,” whose name he could not recall, had done it. His story, at least initially, went as follows. He and Reese met the “other dude” (whom he much later identified as Lambert) for the first time less than an hour before the three of them decided to rob a bar. After casing, and rejecting, one bar, Jackson, who admitted to having previously committed at least thirteen armed robberies of bars, made the decision to rob the Prince’s Lounge after ascertaining that a female friend of his was not working that night. Jackson claimed to have waited in the getaway car while Lambert and Reese entered the bar and went upstairs, each armed with a handgun provided by Reese — Lambert was carrying the .32 and Reese the .38, which, as it turned out, was the murder weapon. Jackson claimed not to have known what happened in the bar aside from what he was told by Reese and Lambert when they returned to the car and fled the scene with Jackson at the wheel.
*131 V. Discussion
It is undisputed that without Jackson’s statements to the police, the Commonwealth could not have indicted Lambert on these charges.
See Giglio v. United States,
But we digress.
A.
Jackson’s statements of October 14, 1982, October 22, 1982, January 14, 1983, and February 6, 1983 were devastatingly inconsistent with each other and with his story at trial. He initially decided to give the police only “some of the truth” and told the рolice that Reese had admitted to shooting two people (A2002); then he told the police that Reese said Lambert was the shooter and that Reese was ordering the barmaid to give him the money (A2007, 2013); then he told the police that although he had previously said that Lambert had done it, that wasn’t true — he was “feeding them a story” when he said that Lambert said he had shot two people and “that was a lie, too.” (A2080, 2082, 2100.) Now, at trial, he said, he was going to tell the truth. It was Reese, not Lambert, who said that he shot two рeople, but that wasn’t true either because what Reese really said was that “I think we killed a couple of guys in there,” not that he did. (A2253.) Indeed, Jackson was finally forced to admit that three months after the first of his lengthy statements to the police, he was still giving them different versions of what had happened. Still, breathtakingly, at the very end of his testimony, with his credibility hanging, at best, by a thread, and conceding that he was testifying to avoid a death sentence, Jackson somewhat proudly announced that although he had “switched what [Lambert and .Reese] did interchangeably,” he always said that Lambert and Reese were the two men involved — they were “the only two people” he supplied to the police. (A2266-67, 2276.)
But that was simply not so, and neither the defense nor the jury was told that it was not so. In the Police Activity Sheet of October 25, 1982, which first came to light during the PCRA proceedings, Jackson named Lawrence Woodlock as a “co-defendant.” (A3334.) The Commonwealth conceded at oral argument before us that the Police Aсtivity Sheet should have been disclosed to the defense prior to trial. Aside from the other arguments made as to why that Police Activity Sheet was significant, there can be no question that given Jackson’s consistent position — his only consistent position, by his own admission, not to mention the evidence at trial — that the only participants were Lambert and Reese in the bar and Jackson in the car, the naming of another participant could well have destroyed what little was left of his credibility.
The PCRA Court considered whether the Commonwealth’s failure to disclose Jackson’s statement that there was another participant — a “co-defendant” — was material such that, as the Supreme Court explained, “there is a reasonable probabili
*132
ty that, had the evidence been disclosed to the defense, the result of the proceeding would have been different.”
Strickler v. Greene,
would not have materially furthered the impeachment of Jackson at trial as he was already extensively impeachеd by both appellant and Reese. Indeed, each codefendant cross-examined Jackson on the following: every inconsistency in his four police statements; that he was testifying on behalf of the Commonwealth pursuant to a plea bargain; and that he had several open robbery charges still pending and his testimony was motivated by a desire to receive lenient sentences for those crimes. Any additional impeachment of Jackson arising from a police notation wоuld have been cumulative. Accordingly, the Commonwealth did not violate Brady by not disclosing this police activity sheet as appellant has failed to show its materiality.

“[O]ur duty to search for constitutional error with painstaking care is never more exacting than it is in a сapital ease.”
Kyles v. Whitley,
“A state-court decision that correctly identifies the governing legal rule but applies it unreasonably to the facts of a particular prisoner’s case certainly would qualify as a decision involving an unreasonable application of clearly established Federal law.”
Williams v. Taylor,
C.
In
Brady v. Maryland,
the Supreme Court held that “the 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.” 373 U.S at 87,
Information is material “only if there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different.”
Id.
at 682,
The Supreme Court of Pennsylvania ruled that the Police Activity Sheet of October 25, 1982 was immaterial because Jackson was so thoroughly impeached thаt, -ipso facto, additional evidence could not have made a difference. To be sure, “impeachment evidence, if cumulative of
similar
impeachment evidence used at trial ... is superfluous and therefore has little, if any, probative value.”
Conley v. United States,
*134
Yet it is patently unreasonable to presume — without explanation — that whenever a witness is impeached in one manner, any other impeachment becomes immaterial. In a similar context, the Supreme Court has rejected- such an argument. In
Napue v. Illinois,
The logic of
Napue
has been extended to the
Brady
context, both by the Supreme Court of the United States and by various federal courts of appeals. In
Banks v. Dretke,
We have also recognized that undisclosed
Brady
material that would have provided a different avenue of impeachment is material, even where the witness is otherwise impeached.
See Slutzker v. Johnson,
*135
Other federal courts of appeals have echoed the conclusion that additional, noncumulative impeachment material implicates
Brady. See United States v. Torres,
What is critical here is that the undisclosed statement by Jackson that there was another participant — a “co-defendant,” to use his word — was not just one more piece of impeachment material to be placed in a “so what” category because Jackson had already been so thoroughly impeached. Rather, the undisclosed Police Activity Sheet would have opened an entirely new line of impeachment, and would have done far more than simply allow the defense to point out — as it did — that Jackson was inconsistent and often changed his story. The way we know that the undisclosed statement would have opened a new line of impeachment is that by not disclosing it, the prosecution was able to rely on Jackson’s consistency in naming Reese and Lambert as the perpetrators, the
only
point on which he was consistent at trial. The Supreme Court has instructed that we may take the Commonwealth at its word that this was important.
See Kyles,
In closing, we cannot help but observe that the evidence is very strong that Reese, not Lambert, was the shooter, even assuming that Lambert (and not Jackson, as two of the barmaids testified) was in the Prince’s Lounge that night. First, it is undisputed that the .38 was the murder weapon, that the .38 was Reese’s gun and carried by him that night, and that Lambert
(if
he was there) had only the .32. Second, all three barmaids described the shooter as no more than 5'7". Reese is 5'7"; Lambert is 6' to 6'1". Third, the testimony of Janet Ryan, the barmaid who suddenly remembered Lambert as having put the gun in her face, identifying him on Reese’s case only “from the nose up” (although she told the police at the time of the murders that she “didn’t even get a look at the man”) after failing to identify
*136
him on the Commonwealth’s case because “nobody asked me,” was, in a word, bizarre. (A2824, 2844, 2940-41). These examples are precisely the types of evidence which can undermine a court’s faith that the verdict in question is “worthy of confidence.”
Kyles,
VI. Conclusion
The judgment of the District Court is vacatеd, and this matter is remanded. The District Court is directed to conditionally grant the petition for a writ of habeas corpus. The Commonwealth shall retry Lambert within 120 days. If it fails to do so, Lambert shall be released.
Notes
. Given this disposition, our order of November 23, 2010, which vacated the sentence of death given our conclusion that the jury instructions violated
Mills v. Maryland,
. Lambert's habeas petition was stayed pending exhaustion of the claims raised in that petition in his subsequently filed third PCRA petition.
. Unlike in
Lisa Michelle Lambert,
the impeachment at issue here is not simply “an additional basis on which to impeach.” Rather, as the First Circuit has recognized, “[cjonfidence in the outcome is particularly doubtful when the withheld evidence impeaches a witness whose testimony is uncorroborated and essential to the conviction.”
