Edwin Cruz seeks to appeal the district court’s order denying relief on his 28 U.S.C. § 2254 (2000) petition. The order is not appealable unless a circuit justice or judge issues a certificate of appealability. See 28 U.S.C. § 2253(c)(1) (2000). A certificate of appealability will not issue absent “a substantia] 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 *619 district court is debatable or wrong and that any dispositive procedural ruling by the district court is likewise debatable. See 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' Cruz has not made the requisite showing. Accordingly, we deny a certifícate of appealability, deny Cruz’s motion for appointment of counsel, 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.
