    UNITED STATES of America, Plaintiff-Appellee, v. John Douglas JACKSON, a/k/a Buddy Dean, Defendant-Appellant.
    No. 11-6424.
    United States Court of Appeals, Fourth Circuit.
    Submitted: July 21, 2011.
    Decided: July 25, 2011.
    John Douglas Jackson, Appellant pro se. Christine Manuelian, Assistant United States Attorney, Baltimore, Maryland, for Appellee.
    Before NIEMEYER and GREGORY, Circuit Judges, and HAMILTON, Senior Circuit Judge.
   Dismissed by unpublished PER CURIAM opinion.

Unpublished opinions are not binding precedent in this circuit.

PER CURIAM:

John Douglas Jackson 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.2011) motion and dismissing it on that basis. The order is not appealable unless a circuit justice or judge issues a certifícate of appealability. 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 Jackson has not made the requisite showing. Accordingly, we deny a certificate of appealability and dismiss the appeal.

Additionally, we construe Jackson’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, not previously discoverable by due diligence, 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, previously unavailable, made retroactive by the Supreme Court to cases on collateral review. 28 U.S.C.A. § 2255(h) (West Supp. 2011). Jackson’s claim does 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 the court and argument would not aid the decisional process.

DISMISSED.
