    UNITED STATES of America, Plaintiff-Appellee, v. Darian Kendell ROBINSON, Defendant-Appellant.

    Submitted: May 30, 2013.
    Decided: June 5, 2013.
    
      Darían Kendell Robinson, Appellant Pro Se. Thomas Richard Ascik, Amy Elizabeth Ray, Assistant United States Attorneys, Jill Westmoreland Rose, Office of the United States Attorney, Asheville, North Carolina, for Appellee.
    Before SHEDD, DIAZ, and THACKER, Circuit Judges.
   Dismissed by unpublished PER CURIAM opinion.

Unpublished opinions are not binding precedent in this circuit.

PER CURIAM:

Darían Kendell Robinson seeks to appeal the district court’s order treating his Fed.R.Civ.P. 60(b) motion as a successive 28 U.S.C.A. § 2255 (West Supp.2012) motion, and dismissing it on that basis. The order is not appealable unless a circuit justice or judge issues a certificate of ap-pealability. 28 U.S.C. § 2253(c)(1)(B) (2006). 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) (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 Robinson has not made the requisite showing. Accordingly, we deny a certificate of appealability, deny leave to proceed in forma pauperis, and dismiss the appeal.

Additionally, we construe Robinson’s notice of appeal and informal brief as an application to file a second or successive § 2255 motion. United States v. Winestock, 340 F.3d 200, 208 (4th Cir.2003). In order to obtain authorization to file a successive § 2255 motion, a prisoner must assert claims based on either:

(1) newly discovered evidence that ... would be sufficient to establish by clear and convincing evidence that no reasonable factfinder would have found the movant guilty of the offense; or
(2) a new rule of constitutional law, made retroactive to cases on collateral review by the Supreme Court, that was previously unavailable.

28 U.S.C.A. § 2255(h) (West Supp.2012). Robinson’s claims do not satisfy either of these criteria. Therefore, we deny authorization to file a successive § 2255 motion.

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.
