Little Tom Childress seeks to appeal the district court’s orders denying his motion to reopen the appeal time to allow him to appeal the denial of his motion filed under 28 U.S.C. § 2255 (2000). An appeal may not be taken from the final order in a § 2255 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 for claims addressed by the district court on the merits 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 that his constitutional claims are 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, 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 Childress has not made the requisite showing. The issue of whether the district court properly denied Childress a further extension of time to appeal the denial of his § 2255 motion, beyond the extension already granted by the district court pursuant to Fed. R.App. P. 4(a), previously was considered by this court and determined adversely to Childress. United States v. Childress, No. 03-6077, 2003 WL 604059 (4th Cir. 2003) (unpublished). This court will not revisit that issue. Boeckenhaupt v. United States, 537 *792 F.2d 1182, 1183 (4th Cir. 1976). * Accordingly, we deny 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.
