    UNITED STATES of America, Plaintiff-Appellee, v. Ronnie Earl KNOX, Defendant-Appellant.
    No. 12-7987.
    United States Court of Appeals, Fourth Circuit.
    Submitted: Feb. 26, 2013.
    Decided: March 1, 2013.
    Ronnie Earl Knox, Appellant Pro Se. Amy Elizabeth Ray, Assistant United States Attorney, Asheville, North Carolina, for Appellee.
    Before MOTZ, WYNN, and DIAZ, Circuit Judges.
   Dismissed by unpublished PER CURIAM opinion.

Unpublished opinions are not binding precedent in this circuit.

PER CURIAM:

Ronnie Earl Knox seeks to appeal the district court’s order dismissing as untimely his 28 U.S.C.A. § 2255 (West Supp. 2012) motion. The order is not appealable unless a circuit justice or judge issues a certificate of appealability. 28 U.S.C. § 2253(c)(1)(B) (2006). A certificate 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. 473, 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 Knox has not made the requisite showing. Accordingly, we deny a certifícate of appealability and dismiss the appeal. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.

DISMISSED.
