OPINION

KING, Circuit Judge.

This matter was previously before us on appeal by 28 U.S.C. § 2254 petitioner Justin Michael Wolfe, a Virginia prisoner who was convicted of capital murder and sentenced to death by the Commonwealth in 2002. By our decision of May 11, 2009, see Wolfe v. Johnson, 565 F.3d 140 (4th Cir. 2009) ("Wolfe I"), we remanded for further proceedings. Specifically, Wolfe I instructed the district court to determine whether Wolfe was entitled to an evidentiary hearing and other discovery; to decide in the first instance whether, under Schlup v. Delo, 513 U.S. 298 (1995), Wolfe had made a sufficient showing of actual innocence to clear any procedural bars to his constitutional claims (the "Schlup issue"); and to assess anew Wolfe's claim, among others, that the prosecution had contravened his Fourteenth Amendment due process rights, as recognized in Brady v. Maryland, 373 U.S. 83 (1963), by suppressing favorable and material evidence (the "Brady claim").

On remand, the district court heeded our Wolfe I mandate, authorized appropriate discovery and conducted an evidentiary hearing, and ruled in Wolfe's favor on the Schlup issue and his Brady and two additional claims. By its judgment of August 30, 2011, the court vacated Wolfe's capital murder and other convictions, and ordered the Commonwealth to either retry him within 120 days or release him unconditionally from custody. The judgment was stayed pending this appeal by the Commonwealth, which was initiated on its behalf by respondent Harold W. Clarke, Director of the Virginia Department of Corrections.1 The Commonwealth challenges the remand proceedings from start to finish, contending that the district court repeatedly and fatally erred in its procedural and substantive rulings. Because we readily conclude, however, that the court's award of habeas corpus relief on Wolfe's Brady claim was not marred by any error, we affirm the judgment.

I.

A.

As more fully detailed in our Wolfe I decision, a Prince William County jury found Wolfe guilty in 2002 of capital murder, using a firearm in the commission of a felony, and conspiring to distribute marijuana. See Wolfe I, 565 F.3d at 149. The trial court sentenced Wolfe to death for the murder, plus consecutive terms of three years for the firearm offense and thirty years for the drug conspiracy. Id. The murder conviction was premised on evidence that Wolfe, then a nineteen-year-old marijuana dealer in northern Virginia, hired his close friend and fellow drug dealer Owen Barber IV to murder drug supplier Daniel Petrole in March 2001. Id. at 144-45 & n.2 (explaining that "Virginia defines `capital murder,' in pertinent part, as `[t]he willful, deliberate, and premeditated killing of any person by another for hire'" (quoting Va. Code Ann. § 18.2-31(2))). Significantly, "Barber was the prosecution's key witness," in that he was "the only witness to provide any direct evidence regarding the `for hire' element of the murder offense and the involvement of Wolfe therein." Id. at 144. In exchange for Barber's testimony that he was Wolfe's hired triggerman, the Commonwealth dismissed its capital murder charge against Barber, and he pleaded guilty to non-capital murder. Barber was sentenced to sixty years in prison, of which twenty-two years were suspended. Id. at 144 n.1.

In November 2005, after failing to obtain relief from his convictions on direct appeal and in state habeas corpus proceedings, Wolfe filed his initial 28 U.S.C. § 2254 petition in the district court. See Wolfe I, 565 F.3d at 149-51. It was only thereafter, on December 14, 2005, that Barber executed an affidavit repudiating his trial testimony and exculpating Wolfe from the murder-for-hire scheme. Id. at 144, 151. Within a single day, Wolfe filed an amended § 2254 petition, along with an appendix of supporting materials, including additional affidavits corroborating the Barber affidavit and suggesting that the prosecution had suppressed evidence that should have been disclosed to the defense. Id. at 151. The amended petition raised, inter alia, the Schlup actual innocence issue, thereby asserting a second ground to excuse any procedural default of Wolfe's constitutional claims — the previously asserted first ground having been the separate "cause and prejudice" standard. Id. at 154, 158 & n.27. In April 2006, while the amended petition and related procedural issues were pending before the magistrate judge, Wolfe notified the court that Barber sought to repudiate the statements in his 2005 affidavit exculpating Wolfe. Id. at 155-56. In conjunction with that notice, Wolfe's lawyers requested an evidentiary hearing to resolve credibility issues, plus discovery into the prosecution's compliance with its Brady obligations. Id. at 156.

In August 2007, the magistrate judge issued his report, rejecting Wolfe's request for an evidentiary hearing, deeming the Barber and other affidavits to lack credibility, and recommending the dismissal of Wolfe's amended petition on the ground that the claims asserted therein were meritless, had been procedurally defaulted, or both. See Wolfe I, 565 F.3d at 156 & n.25. Although Wolfe spelled out a lengthy series of objections to the magistrate judge's report, the district court, by its decision of February 11, 2008, adopted the report as its own and dismissed Wolfe's petition. Id. at 158-59 (explaining, inter alia, that the court did not address the Schlup issue, but "considered (and rejected) Wolfe's contention that his procedural defaults were excused under the cause and prejudice standard" (internal quotation marks omitted)). After the court declined to alter or amend its decision, we granted Wolfe a 28 U.S.C. § 2253(c) certificate of appealability on his Brady and three other claims. Id. at 159. And, as explained above, we ultimately remanded with instructions for the court to determine Wolfe's entitlement to an evidentiary hearing and other discovery, to decide the Schlup issue in the first instance, and to freshly assess the Brady and two additional claims. Id. at 171. We also advised the court that it was free to revisit its cause and prejudice ruling. Id. at 165 n.35.

B.

Without explicitly reconsidering its prior cause and prejudice ruling, the district court decided the procedural Schlup issue early in the remand proceedings, by its opinion and order of February 4, 2010. See Wolfe v. Clarke, No. 2:05-cv-00432 (E.D. Va. Feb. 4, 2010) (the "Schlup Order").2 The court therein determined, largely on the existing Wolfe I record, that Owen Barber's (subsequently disavowed) recantation of his trial testimony was sufficiently corroborated to "raise doubt in a reasonable juror's mind about the circumstances of the night of the [Daniel Petrole] murder." Schlup Order 10. Indeed — weighing the "two stories of what occurred on the night of the murder, both with hearsay corroboration[,] and almost no other evidence that would support one version over another" — the court concluded that it was "more likely than not that no reasonable juror would have found Wolfe guilty beyond a reasonable doubt." Id. (applying Schlup, 513 U.S. at 327 (requiring petitioner to "show that it is more likely than not that no reasonable juror would have convicted him in the light of the new evidence")). Accordingly, the court announced that Wolfe had "met the Schlup standard," thus justifying review of the merits of his procedurally defaulted constitutional claims. Id. The court also granted Wolfe's request for an evidentiary hearing, as well as discovery. Id. at 13.

During the contentious course of the discovery proceedings, Wolfe had to move to compel the Commonwealth to meet its discovery obligations. A June 4, 2010 hearing on Wolfe's motion revealed, inter alia, that the Commonwealth had provided only unsworn responses to the interrogatories it had answered, had wholly failed to respond to other interrogatories, and was refusing to produce approximately 916 documents that it unilaterally deemed irrelevant. By its order of June 7, 2010, the district court directed the Commonwealth to provide sworn responses to Wolfe's interrogatories, including those previously unanswered, and to allow Wolfe to examine the hundreds of theretofore undisclosed documents, subject to an agreed protective order. See Wolfe v. Clarke, No. 2:05-cv-00432 (E.D. Va. June 7, 2010) (the "Discovery Order").3 To give Wolfe an opportunity to assess the evidence that would be forthcoming under the Discovery Order, the court was constrained to postpone the impending evidentiary hearing.

The evidentiary hearing finally ensued late that autumn, when it was conducted over the four days of November 2-3 and 16-17, 2010. On the second day of the hearing, in response to the Commonwealth's objection to Wolfe's use of newly disclosed evidence in support of his existing Brady and other claims, Wolfe filed a motion to amend his 28 U.S.C. § 2254 petition. See J.A. 4026-27 (arguing that the Commonwealth "has tenaciously fought to deny Wolfe access to any facts that would have enabled him to plead additional Brady. . . sub-claims," and thus "should not be rewarded for playing hide-the-ball" and "should not be allowed to blame Wolfe for lacking the clairvoyance to include these proposed amendments to his 2005 federal habeas petition without the benefit of the withheld documents"). By its mid-hearing order of November 12, 2010, the district court granted Wolfe's motion to amend "out of an abundance of caution," but found that "even in the absence of the [motion], the issues [Wolfe] raises fall squarely within the [existing Brady claim]." See Wolfe v. Clarke, No. 2:05-cv-00432 (E.D. Va. Nov. 12, 2010) (the "Amendment Order").4

Thereafter, by its opinion and order of July 26, 2011, the court determined that Wolfe was entitled to habeas corpus relief premised on, inter alia, the Commonwealth's manifold violations of his Brady rights. See Wolfe v. Clarke, No. 2:05-cv-00432 (E.D. Va. July 26, 2011) (the "Brady Order").5 Specifically, the court ruled in the Brady Order that the prosecution had withheld eight items or groups of favorable and material evidence, falling into three broader categories: (1) evidence tending to impeach triggerman Barber; (2) evidence tending to impeach other prosecution witnesses who corroborated Barber's testimony; and (3) evidence suggesting an alternate theory of the Petrole murder. The court also deemed Wolfe to be entitled to relief on his claim that the prosecution knowingly presented false testimony by Barber, in contravention of Wolfe's Fourteenth Amendment due process rights under Napue v. Illinois, 360 U.S. 264 (1959), and Giglio v. United States, 405 U.S. 150 (1972) (the "Giglio claim"), as well as his claim that the state trial court deprived him of his rights under the Sixth and Fourteenth Amendments to an impartial jury by striking a qualified venireman for cause (the "venireman claim"). Notably, the court closed its Brady Order by specifying that Wolfe's "conviction and sentence" — both in the singular — were vacated. See Brady Order 57.

Wolfe timely filed a Federal Rule of Civil Procedure 59(e) motion to alter or amend the judgment, seeking the district court's clarification that the awarded relief encompassed vacatur of not only his murder conviction and death sentence, but also his convictions and sentences for using a firearm in the commission of a felony and conspiring to distribute marijuana. The court granted Wolfe's motion by its order of August 30, 2011. See Wolfe v. Clarke, No. 2:05-cv-00432 (E.D. Va. Aug. 30, 2011) (the "Relief Order"). The court clarified therein that, "[i]n light of [its] finding that [Wolfe] was denied the right to due process during his state criminal trial, [he] is entitled to a new trial on all charges previously considered by the state court." Relief Order 1-2. That same day, the judgment was amended to direct the Commonwealth to retry Wolfe within 120 days or release him unconditionally. See Wolfe v. Clarke, No. 2:05-cv-00432 (E.D. Va. Aug. 30, 2011) (the "Judgment"). The Judgment was subsequently stayed pending this appeal by the Commonwealth. See Wolfe v. Clarke, No. 2:05-cv-00432 (E.D. Va. Nov. 22, 2011) (the "Stay Order").6

We possess jurisdiction over the Commonwealth's appeal pursuant to 28 U.S.C. § 1291. Further, because we granted Wolfe a certificate of appealability for a cross-appeal, we have 28 U.S.C. §§ 1291 and 2253(c) jurisdiction to consider his contention that the district court should have granted him relief on an additional, unadjudicated claim: that "[e]ven if the prosecutors had no knowledge of Barber's perjury at the time of trial, they do now," and thus his continuing detention by the Commonwealth "`constitute[s] a due process violation.'" See Br. of Appellee 62-63 (quoting Sanders v. Sullivan, 863 F.2d 218, 224 (2d Cir. 1988)) (the "Sanders claim"); see also Brady Order 52 (ruling in favor of Wolfe on his Giglio, rather than Sanders, claim, premised on the finding that the Commonwealth "presented Barber's trial testimony despite having information in its possession indicating that the testimony was false").

As explained below, we need look no further than one item of the first category of evidence withheld from Wolfe's defense by the prosecution — the evidence tending to impeach Barber — to agree with the district court that Wolfe deserves habeas corpus relief on his Brady claim and affirm the Judgment. See Brady Order 42 (observing "that the suppressed habeas evidence relating to Barber alone is enough to warrant habeas relief under Brady"). Consequently, we need not review any issues of substance or procedure related solely to the other withheld evidence underlying Wolfe's Brady claim, or to his Giglio, Sanders, and venireman claims.

II.

A.

The single, plainly momentous item of suppressed Barber impeachment evidence on which we rest today's decision is a written police report reflecting that — before Barber ever asserted that Wolfe hired him to murder Petrole — Prince William County Detective Newsome advised Barber that he could avoid the death penalty by implicating Wolfe. See J.A. 4825-27 (the "Newsome report"). The Newsome report documents Newsome's and fellow Detective Walburn's conversations with Barber during an April 14, 2001 cross-country flight, returning Barber to Virginia upon his arrest in California three weeks after the Petrole murder. In pertinent part, the Newsome report reveals the following:

J.A. 4826-27.

The Commonwealth inexplicably withheld the Newsome report from Wolfe until these 28 U.S.C. § 2254 proceedings in 2010, after Wolfe's first appeal and during the contentious discovery proceedings conducted in the Wolfe I remand. Thus, the Newsome report was among the newly disclosed evidence that the Commonwealth argued was outside the legitimate purview of Wolfe's Brady claim — a contention that was roundly rejected by the district court in its mid-evidentiary-hearing Amendment Order of November 12, 2010. During the evidentiary hearing, as recounted in the court's subsequent Brady Order, "Barber recanted his trial testimony while under oath." Brady Order 50. Barber also engaged in the following exchange with the Commonwealth's lawyer during crossexamination:

J.A. 3751-52. By its Brady Order, the district court found the foregoing testimony by Barber to be "consistent with the suppressed [Newsome] report." See Brady Order 9 n.9. The court also deemed Barber's recantation to be "credible" and generally found his "demeanor and candor" to be "persuasive." Id. at 50.

Among the enumerated findings of fact in the district court's Brady Order is the finding (No. 6) that "[t]he prosecution failed to disclose Detective Newsome's report outlining his initial interview with Owen Barber on April 14, 2001, during which he [Newsome] implicated Wolfe as being involved in the murder before Barber mentioned his [Wolfe's] involvement." Brady Order 8. The court also spelled out the controlling legal standard for assessing Wolfe's Brady claim, observing that, "to find a Brady violation, it must determine that the evidence was 1) favorable to the accused, 2) suppressed by the prosecution (either willfully or inadvertently), and 3) material." Id. at 4 (citing Banks v. Dretke, 540 U.S. 668, 691 (2004)). In concluding that the emergence of the Newsome report entitled Wolfe to habeas corpus relief, the court explained:

Id. at 20.7

B.

According to the Commonwealth, we should not reach or address the merits of the Newsome report aspect of Wolfe's Brady claim, because the Newsome report would never have surfaced or been made available to Wolfe but for the flawed procedural rulings made by the district court in the Wolfe I remand proceedings. In that regard, the Commonwealth asserts that the court erred in three respects: by generally excusing Wolfe's procedural defaults under the Schlup actual innocence standard; by authorizing discovery and conducting the evidentiary hearing; and by allowing Wolfe to amend his 28 U.S.C. § 2254 petition to broaden his Brady claim to include the Newsome report and other newly disclosed evidence. We examine those assertions in turn.

1.

Attacking the Schlup Order, the Commonwealth argues that the district court erred by ruling early in the remand proceedings that Wolfe satisfied the Schlup actual innocence standard on the basis of the Wolfe I record, including the 2005 affidavit in which Barber recanted his trial testimony and denied Wolfe's involvement in the Petrole murder. The Commonwealth emphasizes that the court, in looking at that same record, had already decided that the Barber affidavit lacked credibility. See Br. of Appellant 47 ("The court never explained its about face and the record certainly did not justify any finding of `innocence' under Schlup . . . ."). Wolfe, of course, defends the Schlup Order, asserting that "the correctness of the district court's findings was confirmed when Barber recanted his trial testimony while under oath at the [post-Schlup Order] evidentiary hearing." See Br. of Appellee 19-20 (internal quotation marks omitted); see also Brady Order 50 (finding Barber's evidentiary hearing recantation "credible" and his "demeanor and candor persuasive").

In any event, we need not reach or assess the parties' competing contentions on the validity of the Schlup Order. Put simply, any procedural default of Wolfe's Brady claim — particularly as it relates to the Newsome report — was otherwise excused under the separate "cause and prejudice" standard. As we explained in Wolfe I,

Wolfe I, 565 F.3d at 158 n.27 (alteration in original). On remand, after having decided the Schlup issue in Wolfe's favor, the district court understandably declined our Wolfe I invitation to revisit its prior cause and prejudice ruling. See id. at 165 n.35. Nevertheless, pursuant to Supreme Court precedent, the district court necessarily found cause and prejudice for the Brady claim's default when it determined that claim to be meritorious. See Banks, 540 U.S. at 691 (recognizing that "`[c]ause and prejudice' . . . `parallel two of the three components of the alleged Brady violation itself'" (quoting Strickler v. Greene, 527 U.S. 263, 282 (1999))).

To illustrate, as recognized by the district court, "the three components or essential elements of a Brady prosecutorial misconduct claim" are the following: "`The evidence at issue must be favorable to the accused, either because it is exculpatory, or because it is impeaching; that evidence must have been suppressed by the State, either willfully or inadvertently; and prejudice must have ensued.'" Banks, 540 U.S. at 691 (quoting Strickler, 527 U.S. at 281-82). By satisfying "the second Brady component (evidence suppressed by the State), a petitioner shows `cause' when the reason for his failure to develop facts in state-court proceedings was the State's suppression of the relevant evidence." Id. Additionally, "coincident with the third Brady component (prejudice), prejudice within the compass of the `cause and prejudice' requirement exists when the suppressed evidence is `material' for Brady purposes." Id.

Thus, by "succeed[ing] in establishing the elements of his [Brady] claim" — which we today affirm that he did — Wolfe concurrently "succeed[ed] in demonstrating `cause and prejudice' [for his procedural default of that claim]." See Banks, 540 U.S. at 691. By these circumstances, the Commonwealth's challenge to the Schlup Order is rendered moot.

2.

Next, the Commonwealth asserts the district court erred in the remand proceedings by authorizing discovery and conducting the evidentiary hearing. In rejecting the Commonwealth's position, we emphasize that the court faithfully followed our Wolfe I directions to "re-examine whether Wolfe has shown that he is entitled to [an evidentiary hearing]," and then, "[i]f such a hearing is warranted," to "resolve any factual disputes bearing on the procedural Schlup issue and the substantive Brady and Giglio claims." See Wolfe I, 565 F.3d at 170-71. We also observe that Wolfe I pragmatically anticipated that discovery would be conducted in conjunction with any evidentiary hearing. See id. at 171 n.44 (advising that, "[i]f the court determines that Schlup is satisfied on the existing record, any evidentiary hearing and discovery proceedings may relate primarily to the merits of Wolfe's substantive claims" (emphasis added)). We therefore conclude that, in authorizing discovery and conducting the evidentiary hearing, the district court acted well within its discretion. See Schriro v. Landrigan, 550 U.S. 465, 473 (2007) (recognizing that "the decision to grant an evidentiary hearing [in a 28 U.S.C. § 2254 case is] generally left to the sound discretion of the district courts"); see also Conaway v. Polk, 453 F.3d 567, 582 (4th Cir. 2006) (relating that district court's decision on whether to conduct evidentiary hearing or authorize discovery proceedings is reviewed for abuse of discretion).

Briefly, as we more thoroughly explained in Wolfe I, 565 F.3d at 166-71, if a § 2254 petitioner "has failed to develop the factual basis of a claim in State court proceedings," § 2254(e)(2) bars a district court from conducting an evidentiary hearing on the claim unless the petitioner can satisfy one of two statutory exceptions. Importantly, however, "`a failure to develop the factual basis of a claim is not established unless there is lack of diligence, or some greater fault, attributable to the prisoner or the prisoner's counsel.'" Wolfe I, 565 F.3d at 167 (quoting Williams (Michael) v. Taylor, 529 U.S. 420, 432 (2000)); see also Cullen v. Pinholster, 131 S.Ct. 1388, 1401 (2011) (recently affirming that § 2254(e)(2) "continues to have force," in that it "still restricts the discretion of federal habeas courts to consider new evidence when deciding claims that were not adjudicated on the merits in state court" (citing Michael Williams, 529 U.S. at 427-29)).

Applying the controlling standard on remand, the district court determined that § 2254(e)(2) did "not bar [Wolfe] from an evidentiary hearing." See Schlup Order 11. In so ruling, the court observed that Wolfe had made diligent efforts in the state court proceedings to develop his Brady claim by "request[ing] a hearing," "fil[ing] requests under the Virginia Freedom of Information Act," and "mov[ing] for discovery on multiple occasions." Id. at 10. Moreover, with respect to the exculpatory 2005 Barber affidavit on which Wolfe's federal habeas petition largely relied, the court found that "[t]here [was] no indication that Barber would have been willing to give his affidavit at an earlier time, particularly as [Wolfe's] lawyers had repeatedly attempted to get Barber to make a statement and he had refused." Id. at 11. The court thus concluded that Barber's prior reticence was "precisely the type of external cause that . . . excuses a failure to fully develop facts in state court." Id. (citing Conaway, 453 F.3d at 589 (explaining that, because petitioner had "been reasonably diligent in pursuing his claim, and his failure to fully develop the facts related to [his] claim in state court is attributable to external causes, § 2254(e)(2) does not preclude him from being accorded an evidentiary hearing in federal court")).

Having decided that Wolfe was eligible to be accorded an evidentiary hearing, the district court then turned to the question of whether he was entitled to one. That inquiry required the court to determine "`if the facts alleged would entitle [Wolfe] to relief, and if he satisfie[d] one of the six factors enumerated by the Supreme Court in Townsend v. Sain, 372 U.S. 293, 313 (1963).'" See Wolfe I, 565 F.3d at 169 (quoting Conaway, 453 F.3d at 582). Properly "evaluat[ing Wolfe's petition] pursuant to the principles of Federal Rule of Civil Procedure 12(b)(6)," see id., the court concluded that Wolfe set forth sufficient facts to state meritorious Brady and Giglio claims. See Schlup Order 12 (observing that Wolfe "alleged serious violations of his rights," and that those "allegations [were] made even without the benefit of discovery that could lead to considerable additional exculpatory material"). The court also ruled that Wolfe "met at least three of the six [Townsend] factors," in that "`the merits of the factual dispute were not resolved in the state hearing'" (factor 1); "`there is a substantial allegation of newly discovered evidence'" (factor 4); and "`the material facts were not adequately developed at the state-court hearing'" (factor 5). Id. at 12 (quoting Townsend, 372 U.S. at 313); see also Wolfe I, 565 F.3d at 313 (observing that factors 1, 4, and 5 "appear to be applicable here"). Accordingly, the court granted Wolfe's request for an evidentiary hearing, as well as his motion for predicate discovery.

Far from abusing its discretion, the district court engaged in a sound assessment of the evidentiary hearing issue. Premised on that analysis, the court also appropriately (if not explicitly) found that Wolfe had demonstrated "good cause" for discovery. See Quesinberry v. Taylor, 162 F.3d 273, 279 (4th Cir. 1998) ("Good cause is shown if the petitioner makes a specific allegation that shows reason to believe that the petitioner may be able to demonstrate that he is entitled to relief."). As a result of the foregoing, Wolfe properly obtained new and relevant evidence, including the Newsome report, in the remand proceedings.

3.

The Commonwealth nevertheless persists in its efforts to thwart Wolfe's reliance on the Newsome report and other newly disclosed evidence, asserting on appeal that Wolfe was erroneously allowed to amend the Brady claim alleged in his 2005 federal habeas petition. See Br. of Appellant 43 (accusing the district court of "an abuse of judicial power"). The Commonwealth's weak — though strident — contentions in that respect do not long detain us. First of all, we agree with the district court that an amendment of Wolfe's § 2254 petition was not necessary, because his new evidence-related issues "fall squarely within the [existing Brady claim]." Amendment Order 2 (specifying that Wolfe's motion to amend was granted "merely out of an abundance of caution"); see also J.A. 2854 (Wolfe's 2005 federal habeas petition, broadly alleging that the Commonwealth violated his Brady rights by suppressing, inter alia, "[e]xculpatory and impeachment evidence related to the Commonwealth's key witness, Owen Barber").

Furthermore, we reject the Commonwealth's unfounded depiction of "last-minute amendments far beyond the scope of remand [in violation of] the `mandate rule.'" See Br. of Appellant 43. To the contrary, our Wolfe I mandate explicitly authorized the district court to conduct "such other and further proceedings as may be appropriate." See 565 F.3d at 171. In any event, it is difficult to take seriously the Commonwealth's protestations of unfair ambush, when Wolfe had to labor for years from death row to obtain evidence that had been tenaciously concealed by the Commonwealth, and that the prosecution obviously should have disclosed prior to Wolfe's capital murder trial.

C.

With Wolfe's procedural hurdles behind us, we proceed to consider the substance of his Brady claim. Because we focus on an aspect of that claim — the long-concealed Newsome report — that was not adjudicated in the state court proceedings, we owe no 28 U.S.C. § 2254(d) deference to any state decision. See Monroe v. Angelone, 323 F.3d 286, 297 (4th Cir. 2003) ("[Section 2254(d)'s] deference requirement does not apply when a claim made on federal habeas review is premised on Brady material that has surfaced for the first time during federal proceedings."); see also Winston v. Pearson, 683 F.3d 489 (4th Cir. 2012). Rather, we review the district court's "legal conclusions de novo and findings of fact for clear error." Monroe, 323 F.3d at 299.

1.

As previously explained, to succeed on his Brady claim, Wolfe is first required to show that the Newsome report is "favorable to [him], either because it is exculpatory, or because it is impeaching." See Banks v. Dretke, 540 U.S. 668, 691 (2004) (internal quotation marks omitted). The Newsome report is indubitably impeaching, in that it establishes a motive not only for Barber to implicate someone else, but to point the finger specifically at Wolfe. Indeed, it cannot be trivialized that — as Detective Newsome's own report demonstrates — Newsome fed Barber the crux of his testimony, i.e., that he was hired by Wolfe to murder Petrole. Put simply, the Newsome report is crucial, impeaching evidence that was "unquestionably subject to disclosure under Brady." See Spicer v. Roxbury Corr. Inst., 194 F.3d 547, 556 (4th Cir. 1999).

2.

Wolfe next must establish that the Newsome report was "suppressed by the State, either willfully or inadvertently." See Banks, 540 U.S. at 691 (internal quotation marks omitted). The Commonwealth did not contest the suppression issue in the district court proceedings, and does not do so in this appeal. Because the Commonwealth concedes that it withheld the Newsome report, and because the willfulness or inadvertence of its transgression is inconsequential to our Brady analysis, we could say no more on the issue. Nevertheless, we feel compelled to acknowledge that the Commonwealth's suppression of the Newsome report, as well as other apparent Brady materials, was entirely intentional.

During Wolfe's evidentiary hearing in the district court, the Commonwealth's Attorney explained that his office does not have an "open-file policy," providing criminal defense counsel access to entire case files. See J.A. 3690. Asked to elaborate, he offered the flabbergasting explanation that he has "found in the past when you have information that is given to certain counsel and certain defendants, they are able to fabricate a defense around what is provided." Id. Additionally, the Assistant Commonwealth's Attorney admitted that he does not produce evidence to a criminal defendant unless he first deems it to be "material[ ]" and "credib[le]." Id. at 3782. The district court rightly lambasted that conduct in its Brady Order:

Brady Order 43 n.24; see also Muhammad v. Kelly, 575 F.3d 359, 370 (4th Cir. 2009) (refusing to condone the suppression of evidence by the Prince William County prosecutors, and advising them to "err on the side of disclosure, especially when a defendant is facing the specter of execution"). We sincerely hope that the Commonwealth's Attorney and his assistants have finally taken heed of those rebukes.

3.

Of course, Wolfe is yet ineligible for § 2254 relief on his Brady claim unless he makes a third showing — that "prejudice. . . ensued" from the Commonwealth's suppression of the Newsome report. See Banks, 540 U.S. at 691 (internal quotation marks omitted). The prejudice inquiry requires us to determine if the Newsome report is "material" to Wolfe's guilt, i.e., whether "there is a reasonable probability that, had the [Newsome report] been disclosed, the result of the [trial] would have been different." See Cone v. Bell, 556 U.S. 449, 469-70 (2009). Importantly, a reasonable probability does not mean that Wolfe "would more likely than not have received a different verdict with the [Newsome report]," only that the likelihood of a different result is great enough to "undermine[] confidence in the outcome of the trial." See Kyles v. Whitley, 514 U.S. 419, 434 (1995) (internal quotation marks omitted).

The Commonwealth principally contends that the Newsome report and other Barber impeachment evidence were immaterial, because even without Barber's testimony that Wolfe hired him to murder Petrole, there was overwhelming trial evidence of Wolfe's guilt. Concomitantly, the Commonwealth asserts that the district court ignored important pieces of non-Barber evidence, and thus improperly failed to weigh them in the Brady Order materiality analysis. The Commonwealth's argument is belied by the Brady Order, which carefully outlined the trial evidence and came to the inevitable conclusion that "Owen Barber's testimony was the only evidence that the Prosecution presented to prove that [Wolfe] hired Barber to kill Petrole." Brady Order 41. Upon our own review of the trial record in the Wolfe I appeal, we also grasped that "Barber was the prosecution's key witness in Wolfe's capital trial and the only witness to provide any direct evidence regarding the `for hire' element of the murder offense and the involvement of Wolfe therein." Wolfe I, 565 F.3d at 144. And, the Commonwealth itself conceded at Barber's sentencing hearing on his non-capital murder conviction — where he received a sentence of just sixty years in prison, with twenty-two years suspended — that "but for [Barber's] testimony Mr. Wolf[e] probably would not have been prosecuted." J.A. 5144.

In these circumstances, where "the jury had to believe that Barber was credible and that his version of events was in fact truthful and accurate in order to support [Wolfe's] conviction," Brady Order 41, the materiality of the Newsome report is manifest. See Smith v. Cain, 132 S.Ct. 627, 630 (2012) (holding that, where an eyewitness's "testimony was the only evidence linking [the defendant] to the crime," the eyewitness's undisclosed prior inconsistent statements "were plainly material"); Harris v. Lafler, 553 F.3d 1028, 1034 (6th Cir. 2009) ("Considerable authority from the Supreme Court and our court indicates that a defendant suffers prejudice from the withholding of favorable impeachment evidence when the prosecution's case hinges on the testimony of one witness."); Monroe, 323 F.3d at 315-16 (explaining that, because a witness's testimony was "crucial" to proving premeditation, there was "a reasonable probability that [the defendant] would not have been convicted of first-degree murder" if evidence tending to impeach the witness had been properly disclosed). Wolfe therefore satisfies the third and final element of his Brady claim.8

D.

Having confirmed that Wolfe is entitled to 28 U.S.C. § 2254 relief, the only remaining issue before us is whether the district court properly vacated all three of Wolfe's convictions, including his conviction for conspiring to distribute marijuana, for which he received the statutory maximum sentence of thirty years. See Relief Order 1 (deeming full vacatur appropriate because the Commonwealth's "Brady and Giglio violations . . . permeated the fairness of [Wolfe's] trial on all charges"). In contesting the court's vacatur decision, the Commonwealth criticizes the court's reliance on Federal Rule of Civil Procedure 59(e) to amend the Judgment. Unfortunately for the Commonwealth, the court acted well within its discretion. See Robinson v. Wix Filtration Corp. LLC, 599 F.3d 403, 407 (4th Cir. 2010) (explaining that "a court may alter or amend the judgment if the movant shows[, inter alia,] that there has been a clear error of law or a manifest injustice," subject to review "under the deferential abuse of discretion standard").

The Commonwealth further asserts that the district court improperly vacated Wolfe's drug conspiracy conviction because it was unaffected by the suppression of any Brady material. Significantly, it is the Commonwealth's position that the drug conviction and attendant thirty-year sentence were secured on the basis of Wolfe's trial testimony, wherein he "not only admitted to drug dealing, but bragged about dealing on a massive scale." See Br. of Appellant 57 (contending that, in light of Wolfe's self-incriminating testimony, "[t]here was no likelihood, much less a reasonable one, that Wolfe would not have been convicted of conspiracy to distribute marijuana had the allegedly withheld evidence about Wolfe's part in the murder been disclosed"). The Commonwealth emphasizes that "Wolfe's unrepentant braggadocio was the focus of the Commonwealth's closing arguments" and "justified the Commonwealth's call for the maximum sentence." Id. Indeed, although the Commonwealth refers in its opening brief to "overwhelming evidence of a far-reaching drug conspiracy," id. at 58, the only evidence discussed therein with any specificity is Wolfe's own damning testimony.

In response, Wolfe maintains that, in the absence of the Newsome report and other wrongfully suppressed Barber impeachment evidence, "his only option was to take the stand and stake his word against Barber's — an unattractive option, for as the Commonwealth acknowledges[,] it required Wolfe to admit to committing a felony and risk thirty years' imprisonment." Br. of Appellee 72. According to Wolfe,

Id. at 72-73 (citations, alteration, and internal quotation marks omitted).

We are entirely convinced by Wolfe's contentions. Because the Commonwealth concedes that Wolfe's trial testimony was central to his drug conspiracy conviction and sentence, and because the Commonwealth cannot prove that Wolfe would have testified if the Newsome report had not been suppressed, we agree with the district court that Wolfe is entitled to vacatur of all three of his state convictions. Cf. United States v. Pelullo, 105 F.3d 117, 125 (3d Cir. 1997) (concluding that, where the government committed Brady violations that allegedly adduced the defendant's trial testimony, that testimony could not be used against the defendant at a subsequent trial unless the government could prove that "the defendant would have testified anyway even if there had been no constitutional violation" (citing Harrison v. United States, 392 U.S. 219, 225 (1968) ("Having `released the spring' by using the petitioner's unlawfully obtained confessions against him, the Government must show that its illegal action did not induce his testimony."))). Of course, as the district court's Judgment reflects, the Commonwealth is free to retry Wolfe on the murder, firearm, and drug conspiracy charges.9

III.

Pursuant to the foregoing, we affirm the Judgment of the district court.

AFFIRMED.

DUNCAN, Circuit Judge, dissenting in part.

I write with regard and appreciation for the majority's disposition of Wolfe's murder-for-hire and firearm convictions. I must, however, respectfully and narrowly dissent from its granting of habeas relief on the drug conspiracy conviction. The record, and, significantly, the majority does not directly refute it, contains ample evidence from sources other than Wolfe's testimony to support the drug conviction. The district court's Relief Order does not address the merits of the drug conspiracy issue at all, and the case on which it purports to rely is inapposite as to that charge. See Wolfe v. Clarke, No. 1:05-cv-00432 (E.D. Va. Aug. 30, 2011) (citing Monroe v. Angelone, 323 F.3d 286, 293 n.5 (4th Cir. 2003)).*

I fully recognize and appreciate the focus of the district court and the majority on the more serious charges. And, indeed, the Commonwealth did not, in its argument, greatly aid our analysis. The Commonwealth's behavior here is far from exemplary. But the Newsome report cannot carry the weight the majority would assign to it. Because of the amount of evidence as to the drug conspiracy untainted by the Brady violation, I would at the very least remand that conviction to the district court for its specific consideration.
