    UNITED STATES of America, Plaintiff—Appellee, v. Ronald Lee COUCH, Jr., a/k/a D, a/k/a Diablo, Defendant—Appellant.
    No. 08-6084.
    United States Court of Appeals, Fourth Circuit.
    Submitted: April 17, 2008.
    Decided: April 23, 2008.
    Ronald Lee Couch, Jr., Appellant Pro Se. Kevin Michael Comstock, Assistant United States Attorney, Norfolk, Virginia, for Appellee.
    Before WILKINSON, NIEMEYER, and MICHAEL, Circuit Judges.
   PER CURIAM:

Ronald Lee Couch, Jr., seeks to appeal the district court’s order denying his Fed. R.Civ.P. 60(b) motion for reconsideration of the district court’s order denying relief on his 28 U.S.C. § 2255 (2000) motion. The order is not appealable unless a circuit justice or judge issues a certificate of ap-pealability. 28 U.S.C. § 2253(c)(1) (2000); Reid v. Angelone, 369 F.3d 363, 369 (4th Cir.2004). 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 any assessment of the constitutional claims by the district court is debatable or wrong and that any dispositive procedural ruling by the district court is likewise debatable. Miller-El v. Cockrell, 537 U.S. 322, 336-38, 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, 683-84 (4th Cir.2001). We have independently reviewed the record and conclude that Couch has not made the requisite showing. Accordingly, we deny a certificate of appealability and dismiss the appeal.

Additionally, we construe Couch’s notice of appeal and informal brief as an application to file a second or successive motion under 28 U.S.C. § 2255. 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) a new rule of constitutional law, previously unavailable, made retroactive by the Supreme Court to cases on collateral review; or (2) newly discovered evidence, not previously discoverable by due diligence, that would be sufficient to establish by clear and convincing evidence that, but for constitutional error, no reasonable factfinder would have found the movant guilty of the offense. 28 U.S.C. §§ 2244(b)(2), 2255 (2000). Couch’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 the court and argument would not aid the decisional process.

DISMISSED.
