Bobby Wayne Swisher applies to this court for a certificate of appealability (COA) to review the district court's dismissal of his petition under 28 U.S.C.A. § 2254 (West 1994 & Supp.2002).1 Swisher asserted a variety of claims in his habeas petition in the district court. In his motion for a COA, Swisher asserts that he is entitled to relief as to several of those claims including, inter alia, the following: (1) that the Commonwealth, in prosecuting him, knowingly elicited perjurious testimony from a witness and failed to correct the erroneous impression conveyed by that witness's testimony, in violation of the Fourteenth Amendment; (2) that his counsel failed adequately to impeach a witness against him with the witness's prior inconsistent statement to police, thus providing ineffective assistance of counsel in violation of the Sixth Amendment; and (3) that the Commonwealth, in violation of Brady v. Maryland, 373 U.S. 83, 83 S. Ct. 1194, 10 L. Ed. 2d 215 (1963), failed to turn over evidence that a witness against him sought (and possibly received) a monetary reward in exchange for his testimony. Finding that Swisher has not made the requisite substantial showing of the denial of a constitutional right as to any of these claims, we deny Swisher's application for a COA and dismiss his appeal.

The undisputed facts of Swisher's case are summarized in the opinion of the Supreme Court of Virginia resolving Swisher's appeal from his conviction. Swisher v. Commonwealth, 256 Va. 471, 506 S.E.2d 763 (1998). We restate those facts relevant to Swisher's petition briefly below.

On February 5, 1997, Dawn McNees Snyder disappeared from the florist shop where she worked in Augusta County, Virginia. Her body was discovered on February 21, 1997, on the bank of the South River, approximately two miles from the florist shop. Forensic examination revealed that she had been raped, sodomized, and that her death had been caused by some violence to her neck.2

On February 22, 1997, Swisher was at an apartment with two friends, Clarence Henry Ridgeway, Jr. and Shane Knous. Swisher told Ridgeway and Knous that he had abducted, raped, sodomized, and killed Snyder. He stated specifically that on February 5 he entered the florist shop where Snyder worked and told her he had a gun in his pocket. He also threatened Snyder with a butcher's knife. Swisher forced Snyder to accompany him from the florist shop to a field near the South River, where he forced her to perform oral sex on him and remove her clothes. Swisher then raped Snyder and again forced her to perform oral sex on him. Finally, after Snyder put her clothes back on, Swisher cut her face and throat with the butcher's knife and threw her, still alive, into the South River. As Snyder floated in the river, Swisher walked along the bank and shouted, "Are you dead yet?" A few moments later, when she began to crawl up the bank, Swisher "got scared and took off running" away from the river to his house. Swisher, 506 S.E.2d at 765.

Ridgeway notified the Augusta County Sheriff's Office of Swisher's statements on the morning of February 23. Later that day, Swisher accompanied four deputies to the Sheriff's Office for questioning. After being arrested and advised of his Miranda rights, Swisher admitted, in an audiotaped confession, that he had sodomized and raped Snyder, murdered her by cutting her throat, and thrown her into the South River.

Swisher was charged with murder, abduction, rape, and forcible sodomy in Snyder's death. Following a jury trial, the jury found Swisher guilty of all charges on October 29, 1997, including capital murder pursuant to Va.Code Ann. § 18.2-31 (Michie 1996). In the penalty phase of the trial, the Commonwealth presented the testimony of Ridgeway, who testified that Swisher had confessed to him and Knous that he murdered Snyder. Ridgeway testified that Swisher had told him Swisher felt like he could "do it again." (J.A. at 326.) In a previous statement to police, however, Ridgeway stated that he had not heard Swisher say he felt like he could "do it again," but that Knous remembered hearing Swisher make such a statement. (J.A. at 317.) Ridgeway further testified that he had not sought and was not interested in a reward offered for information about Snyder's murder.3 At the conclusion of the penalty phase, the jury fixed Swisher's sentence for Snyder's murder at death, and the trial judge sentenced him to death on February 18, 1998.

Swisher filed a direct appeal, which was consolidated with the automatic review of his death sentence in the Supreme Court of Virginia. See Swisher, 506 S.E.2d at 765; Va.Code Ann. § 17.1-313(A) (Michie 1999) (providing for automatic review of death sentences in the Supreme Court of Virginia); § 17.1-409 (authorizing the Supreme Court of Virginia to certify for its review a case filed with the Virginia Court of Appeals before that court has resolved the case). The Supreme Court of Virginia denied relief. Swisher then filed a petition for a writ of habeas corpus in the Supreme Court of Virginia, see Va.Code Ann. § 8.01-654(C) (Michie 2000) (vesting exclusive jurisdiction in the Supreme Court of Virginia of petitions for writs of habeas corpus by petitioners held under a sentence of death), and was denied relief. Thereafter, he filed a petition pursuant to 28 U.S.C.A. § 2254 in the United States District Court for the Western District of Virginia. On March 28, 2002, the district court denied relief on that petition.4 Swisher seeks a COA as to numerous claims raised in the district court. We address the following three claims below: (1) that the Commonwealth knowingly elicited perjurious testimony; (2) that Swisher received ineffective assistance of counsel; and (3) that the Commonwealth failed to turn over Brady material.5

We may only issue a COA if Swisher has made a "substantial showing of the denial of a constitutional right." 28 U.S.C.A. § 2253(c)(2) (West Supp.2002). Absent a COA, "an appeal may not be taken" to this court from the district court's denial of relief on the § 2254 petition. Id. § 2253(c)(1); cf. Miller-El v. Cockrell, ___ U.S. ___, 123 S. Ct. 1029, 1039, 154 L. Ed. 2d 931 (2003) (noting that a COA is "a jurisdictional prerequisite" to consideration of an appeal by a prisoner denied habeas relief in the district court). To make the requisite substantial showing, "a petitioner must `show that reasonable jurists could debate whether (or, for that matter, agree that) the petition should have been resolved in a different manner or that the issues presented were "adequate to deserve encouragement to proceed further.''"" Id. (quoting Slack, 529 U.S. at 484, 120 S. Ct. 1595 (in turn quoting Barefoot v. Estelle, 463 U.S. 880, 893 & n. 4, 103 S. Ct. 3383, 77 L. Ed. 2d 1090 (1983))).

The Supreme Court has held that "[w]here a district court has rejected [a petitioner's] constitutional claims on the merits, ... [t]he petitioner must demonstrate that reasonable jurists would find the district court's assessment of the constitutional claims debatable or wrong" to obtain a COA. Slack v. McDaniel, 529 U.S. 473, 484, 120 S. Ct. 1595, 146 L. Ed. 2d 542 (2000). Further, "[w]hen the district court denies a habeas petition on procedural grounds without reaching the prisoner's underlying constitutional claim, a COA should issue when the prisoner shows, at least, that jurists of reason would find it debatable whether the petition states a valid claim of the denial of a constitutional right and that jurists of reason would find it debatable whether the district court was correct in its procedural ruling." Slack, 529 U.S. at 484, 120 S. Ct. 1595; cf. Miller-El, 123 S.Ct. at 1046 (Scalia, J., concurring) (noting that "a habeas petitioner seeking to appeal a district court's denial of habeas relief on procedural grounds must not only make a substantial showing of the denial of a constitutional right but also must demonstrate that jurists of reason would find it debatable whether the district court was correct in its procedural ruling"). The Supreme Court has stated that "[t]his construction [of the standard applicable when the district court rejects a claim on procedural grounds] gives meaning to Congress' requirement that a prisoner demonstrate substantial underlying constitutional claims and is in conformity with the meaning of the `substantial showing' standard provided in Barefoot and adopted by Congress in AEDPA." Slack, 529 U.S. at 484, 120 S. Ct. 1595 (internal citation omitted).

The Supreme Court recently provided further guidance on the question of how an application for a COA is to be assessed in Miller-El. The Court's opinion in Miller-El makes clear that whether to grant a COA is intended to be a preliminary inquiry, undertaken before full consideration of the petitioner's claims. Miller-El, 123 S.Ct. at 1039 (noting that the "threshold [COA] inquiry does not require full consideration of the factual or legal bases adduced in support of the claims"); id. at 1040 (noting that "a claim can be debatable even though every jurist of reason might agree, after the COA has been granted and the case has received full consideration, that petitioner will not prevail") (emphasis added); id. at 1042 (noting that "a COA determination is a separate proceeding, one distinct from the underlying merits"); id. at 1046-47 (Scalia J., concurring) (noting that it is erroneous for a court of appeals to deny a COA only after consideration of the applicant's entitlement to habeas relief on the merits). Indeed, such "full consideration" in the course of@ the COA inquiry is forbidden by § 2253(c). Id. at 1039 ("When a court of appeals side steps [the COA] process by first deciding the merits of an appeal, and then justifying its denial of a COA based on its adjudication of the actual merits, it is in essence deciding an appeal without jurisdiction.").

The current posture of this appeal, in which we are called on to determine whether to issue a COA as to issues which have been fully briefed and argued before the panel, is thus out of step with the procedural treatment that the Supreme Court has indicated is appropriate for COA applications under § 2253(c). Unable to rectify that circumstance, we proceed nevertheless to address Swisher's request for a COA under the standard enunciated by the Supreme Court in Slack and Miller-El.

Swisher argues that the Commonwealth knowingly elicited perjurious testimony from Ridgeway during the penalty phase of his trial. Specifically, he asserts that the Commonwealth, knowing Ridgeway had told police he had not heard Swisher say he could "do it again," nevertheless permitted Ridgeway to testify that he had heard Swisher make that statement. Swisher argues that the Commonwealth's having elicited this testimony from Ridgeway, knowing it to be false, and having failed to correct the erroneous impression it created, violated his rights under the Fourteenth Amendment. See Napue v. Illinois, 360 U.S. 264, 269, 79 S. Ct. 1173, 3 L. Ed. 2d 1217 (1959); see also Giglio v. United States, 405 U.S. 150, 153, 92 S. Ct. 763, 31 L. Ed. 2d 104 (1972) (noting that "deliberate deception of a court and jurors by the presentation of known false evidence is incompatible with rudimentary demands of justice") (internal quotation marks omitted).

The district court denied this claim because Swisher could not show cause and prejudice to overcome his procedural default.6 Because, as we discuss briefly below, Swisher has not shown "that jurists of reason would find it debatable whether the district court was correct in its procedural ruling," Slack, 529 U.S. at 484, 120 S. Ct. 1595, we deny the application for a COA on this claim.

Swisher argues that he has demonstrated cause because the Commonwealth's "deliberate use of this perjured testimony was designed to obscure its falsity," (Appellant's Br. at 41), and therefore its use constituted "`interference by officials' that ma[de] compliance with the State's procedural rule impracticable." McCleskey v. Zant, 499 U.S. 467, 494, 111 S. Ct. 1454, 113 L. Ed. 2d 517 (1991) (quoting Murray v. Carrier, 477 U.S. 478, 488, 106 S. Ct. 2639, 91 L. Ed. 2d 397 (1986) (internal quotation marks omitted)). The basis for Swisher's assertion that Ridgeway's testimony was perjurious, however, is the inconsistency between the statement Ridgeway gave to the police and the statement he made on the stand, and Swisher was in possession of Ridgeway's statement to police when Ridgeway testified. Accordingly, no act by the Commonwealth impeded Swisher's ability to raise the claim he now raises at trial or on appeal, and he cannot demonstrate cause for his procedural default on this basis.

Swisher also asserts that he has demonstrated cause stemming from his counsel's ineffectiveness in defaulting this claim. See Burket v. Angelone, 208 F.3d 172, 189 (4th Cir.2000) (constitutionally ineffective assistance of counsel may establish cause for a procedural default); see also Murray v. Carrier, 477 U.S. 478, 488-89, 106 S. Ct. 2639, 91 L. Ed. 2d 397 (1986). The requisite ineffective assistance, however, "is itself an independent constitutional claim" subject to the requirement of exhaustion in state court and to the doctrine of procedural default. Edwards v. Carpenter, 529 U.S. 446, 451, 120 S. Ct. 1587, 146 L. Ed. 2d 518 (2000) (emphasis in original); id. at 453, 120 S. Ct. 1587 (holding that ineffective assistance claims asserted as cause for procedural default of other claims are themselves subject to procedural default rule); see also Carrier, 477 U.S. at 488-89, 106 S. Ct. 2639 (noting that "the exhaustion doctrine ... generally requires that a claim of ineffective assistance be presented to the state courts as an independent claim before it may be used to establish cause for a procedural default"). Swisher does not assert that he can demonstrate cause and prejudice for his procedural default of this ineffective assistance claim. Accordingly, he cannot use ineffective assistance of counsel to demonstrate cause for the failure to raise the use of perjured testimony claim.

Because Swisher has not shown that the district court's procedural ruling was debatable, we deny a COA as to this claim.

Swisher next contends that his counsel was ineffective at trial for failing to cross-examine Ridgeway about the inconsistency between Ridgeway's statement to police, in which he stated that he had not heard Swisher say he felt like he could "do it again," and his testimony at trial, during which he stated that he had heard Swisher make such a statement.7 Because the district court dismissed Swisher's claim on the merits, we ask whether Swisher has shown that "reasonable jurists would find the district court's assessment of the constitutional claims debatable or wrong." Slack, 529 U.S. at 484, 120 S. Ct. 1595.

To obtain relief on an ineffective assistance of counsel claim under Strickland v. Washington, 466 U.S. 668, 104 S. Ct. 2052, 80 L. Ed. 2d 674 (1984), a petitioner must show (1) that his counsel's performance was "deficient in that it fell below an objective standard of reasonableness and outside the wide range of professionally competent assistance ... and (2) that the deficient performance prejudiced the defense in that, but for counsel's unprofessional errors, the result of the proceeding would have been different." Hunt v. Lee, 291 F.3d 284, 289 (4th Cir.2002) (citing Strickland, 466 U.S. at 687-90, 694, 104 S. Ct. 2052) (internal quotation marks omitted). The district court denied relief on this claim, finding both that counsel's performance was objectively reasonable, and "[m]ost importantly," that Swisher could not show prejudice from any errors of counsel because "the jury heard substantial evidence to support findings of vileness and future dangerousness,"8 including physical evidence of the circumstances of the crime, Swisher's own confession,9 and evidence that Swisher had been caught with a razor blade and a "shank" in his cell while awaiting trial at the local jail and that he had repeatedly threatened jailers during that time. (J.A. at 723-24.)

Because Swisher has not shown that reasonable jurists would find the district court's assessment of the claims debatable or wrong, we deny a COA as to this claim.

Swisher also asserts that the Commonwealth, in violation of Brady, failed to turn over to his counsel evidence that Ridgeway sought and received a reward in exchange for his testimony. The district court found that this claim, which Swisher never presented in state court, was "clearly unexhausted," but elected to deny the claim on its merits pursuant to 28 U.S.C.A. § 2254(b)(2) (stating that an application for a writ of habeas corpus in federal court may be denied on the merits, notwithstanding the applicant's failure to exhaust the remedies available in state court). Relying on the evidence of the vileness of Swisher's crime and his future dangerousness, which it had previously discussed, the district court concluded, "[g]iven the strength of other evidence before the jury in support of vileness and future dangerousness, there is no reasonable probability that even the elimination of Ridgeway's testimony would cause a reasonable factfinder to vote for life."10 (J.A. at 741.) We again assess whether jurists of reason would find the district court's assessment of Swisher's claim debatable or wrong. Slack, 529 U.S. at 484, 120 S. Ct. 1595.

It is not entirely clear what evidence or impeachment material Swisher asserts should have been produced. His primary contention appears to be that the Commonwealth had an obligation to turn over evidence that after trial Ridgeway received the reward. He also suggests, however, that Ridgeway "received an explicit promise" before trial that he would receive the reward in exchange for his testimony (Appellant's Br. at 21), and that Ridgeway testified "in hopes of receiving" the reward (Appellant's Br. at 20). To establish a Brady claim, a defendant must demonstrate not only the existence of evidence favorable to the defendant that was suppressed by the government, but also a "reasonable probability" that the result of the proceedings would have been different had the evidence been disclosed. See Jones v. Cooper, 311 F.3d 306, 314 n. 14 (4th Cir.2002).

Even accepting Swisher's allegations as true, we cannot find that any reasonable jurists would conclude that the result of any proceeding in this case would have been different. In rejecting Swisher's claim, the district court referred to the admitted facts of Snyder's murder and the evidence that Swisher had been caught with a shank and a razor blade in his cell while awaiting trial at the local jail, and that he repeatedly threatened his jailers during that time. Based on this evidence, the district court's conclusion that Swisher would have been convicted of capital murder and sentenced to death even if Ridgeway's testimony had been completely impeached by evidence that he was promised, and later received, a reward for his testimony is not debatable. Because Swisher has not shown that reasonable jurists would find the district court's assessment of the claims debatable or wrong, we deny a COA as to this claim.

For the reasons stated above, Swisher's application for a COA is denied and the appeal is dismissed.

DISMISSED.
