UNITED STATES of America, Plaintiff-Appellee, v. Ramon LOO-OLVERA, Defendant-Appellant, 158 F. App'x 502

PER CURIAM: Ramon Loo-Olvera, a federal prisoner, seeks to appeal the district court’s order denying relief on his 28 U.S.C. § 2255 (2000) motion. An appeal may not be taken from the final order in a post-conviction 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 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 the district court’s assessment of his constitutional claims is 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). We have independently reviewed the record and conclude that Loo-Olvera has not made the requisite showing.

On appeal, Loo-Olvera challenges his sentence based on the holding in United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). This court has recently held that Booker is not retroactively applicable to cases on collateral review. United States v. Morris, 429 F.3d 65 (4th Cir.2005). Accordingly, we deny Loo-Olvera’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
