James M. DeBardeleben seeks to appeal the district court’s order dismissing as successive his 28 U.S.C. § 2254 (2000) petition. The order is not appealable unless a circuit justice or judge issues a certificate of appealability. 28 U.S.C. § 2253(c)(1) (2000); Jones v. Braxton, 392 F.3d 683, 688 (4th Cir. 2004). A certificate of appeal-ability will not issue absent “a substantial showing of the denial of a constitutional right.” 28 U.S.C. § 2253(c)(2) (2000). A prisoner satisfies this standard by demonstrating that reasonable jurists would find *842 both that the district court’s assessment of the constitutional claims is debatable or wrong and that any dispositive procedural rulings by the district court are also debatable or wrong. Miller-El v. Cockrell, 537 U.S. 322, 336-38, 123 S.Ct. 1029, 154 L.Ed.2d 931 (2003); Slack v. McDaniel, 529 U.S. 473, 484, 120 S.Ct. 1595, 146 L.Ed.2d 542 (2000); Rose v. Lee, 252 F.3d 676, 683-84 (4th Cir. 2001). We have independently reviewed the record and conclude that DeBardeleben has not made the requisite showing. Accordingly, we deny a certifícate of appealability and dismiss the appeal. No active judge of this court has voted to grant hearing en banc; therefore, we deny DeBardeleben’s petition for initial hearing en banc. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.
