¶1 Mark Todd Showalter seeks to appeal the district court’s order dismissing as untimely his petition filed under 28 U.S.C. § 2254 (2000). An appeal may not be taken from a final order in a habeas corpus proceeding unless a circuit justice or judge issues a certificate of appealability. 28 U.S.C. § 2253(c)(1) (2000). A certificate of appealability 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 *442 would find that the district court’s assessment of his constitutional claims is debatable and that any dispositive procedural rulings by the district court are also debatable or wrong. See Miller-El v. Cockrell, 537 U.S. 322, 336, 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 (4th Cir.2001). We have independently reviewed the record and conclude that Showalter has not made the requisite showing. Accordingly, we deny a certificate of appealability and dismiss the appeal. * We grant Showalter’s motion to place portions of the record (Volumes 2-6) on appeal under seal. 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.
