Andrew Windsor, a federal prisoner, seeks to appeal the district court’s order denying relief on his motion filed under 18 U.S.C. § 3582(c)(2) (2000), which the district court properly construed as a motion under 28 U.S.C. § 2255 (2000). The district court dismissed the motion as untimely. This 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 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, 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). The record demonstrates that the district court lacked jurisdiction to consider the motion as Windsor failed to obtain pre-filing authorization from this court to file it. Windsor’s failure to obtain pre-filing authorization to file the § 2255 motion in the first instance precludes granting a certificate of appealability.

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
