John Samuel Leigh seeks to appeal the district court’s order accepting the recommendation of the magistrate judge and denying relief on his 28 U.S.C. § 2255 (2000) motion. The order is not appeal-able 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 substan *301 tial 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 that any assessment of the constitutional claims by the district court is debatable or wrong and that any dispositive procedural ruling by the district court is likewise debatable. 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 Leigh has not made the requisite showing. Accordingly, we deny Leigh’s motion for a certificate of appealability and dismiss the appeal. 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.

DISMISSED.
