PER CURIAM: Alvin G. Gomez seeks to appeal the district court’s order denying relief on his 28 U.S.C. § 2255 (2000) motion. The order is not appealable 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 would find 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 Gomez has not made the requisite showing.
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. DISMISSED We recently concluded that the rule announced in United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), is not retroactively applicable to cases on collateral review. United States v. Morris, 429 F.3d 65, 72 (4th Cir.2005).
