Dismissed by unpublished PER CURIAM opinion.
Unpublished opinions are not binding precedent in this circuit.
PER CURIAM:Patrick Kit Plumlee seeks to appeal the district court’s order treating his self-styled “Motion to Vacate” as a successive 28 U.S.C.A. § 2255 (West Supp.2011) motion, and dismissing it on that basis.* The *217district court’s order is not appealable unless a circuit justice or judge issues a certifícate of appealability. 28 U.S.C. § 2258(c)(1)(B) (2006). A certifícate of ap-pealability will not issue absent “a substantial showing of the denial of a constitutional right.” 28 U.S.C. § 2253(c)(2) (2006). When the district court denies relief on the merits, a prisoner satisfies this standard by demonstrating that reasonable jurists would find that the district court’s assessment of the constitutional claims is debatable or wrong. Slack v. McDaniel, 529 U.S. 478, 484, 120 S.Ct. 1595, 146 L.Ed.2d 542 (2000); see Miller-El v. Cockrell, 537 U.S. 322, 336-38, 123 S.Ct. 1029, 154 L.Ed.2d 931 (2003). When the district court denies relief on procedural grounds, the prisoner must demonstrate both that the dispositive procedural ruling is debatable, and that the motion states a debatable claim of the denial of a constitutional right. Slack, 529 U.S. at 484-85, 120 S.Ct. 1595. We have independently reviewed the record and conclude that Plumlee 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.
Although the district court also found that Plumlee’s motion was time-barred under the Antiterrorism and Effective Death Penalty Act of 1996, because Plumlee’s motion was a successive § 2255 motion, the district court lacked jurisdiction to consider the timeliness of Plumlee’s motion. See United States v. Winestock, 340 F.3d 200, 205 (4th Cir.2003).
