Philip Murph seeks to appeal the district court’s order denying relief on his motion to reconsider under Fed.R.Civ.P. 60(b), filed in his underlying 28 U.S.C. § 2255 (2000) action. The order is not appealable unless a circuit justice or judge issues a certificate of appealability. 28 U.S.C. § 2253(c)(1) (2000); Reid v. Angelone, 369 F.3d 363, 368-69 (4th Cir. 2004) (holding that appeal from the denial of a Fed. R.Civ.P. 60(b) motion in a habeas action requires a certificate of appealability). 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 his constitutional claims are debatable and that any dispositive procedural rulings by the district court are also debatable or wrong. See 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 (4th Cir. 2001). We have independently reviewed the record and conclude that Murph has not made the requisite showing.

To the extent Murph’s notice of appeal and informal brief could be construed as a motion for authorization to file a successive § 2255 motion, we deny such authorization. United States v. Winestock, 340 F.3d 200, 208 (4th Cir.), cert. denied, 540 U.S. 995, 124 S.Ct. 496, 157 L.Ed.2d 395 (2003). 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.
