UNPUBLISHED

Thomas Davis seeks to appeal the district court’s order denying his Fed. R.Civ.P. 60(b) motion to vacate the district court’s order denying relief on his 28 U.S.C. § 2254 (2006) petition. Davis has unsuccessfully challenged his conviction in a true § 2254 petition. Because Davis’s 60(b) motion was a successive and unauthorized § 2254 petition, see In re Vial, 115 F.3d 1192, 1194 (4th Cir. 1997), the district court was obligated to dismiss the motion, see United States v. Winestock, 340 F.3d 200, 205 (4th Cir. 2003), and the order is not appealable unless a circuit justice or judge issues a certificate of appealability. 28 U.S.C. § 2253(c)(1) (2006); 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) (2006). Wfiien the district court denies relief on the merits, a prison *319 er 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 petition 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 Davis has not made the requisite showing. 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 this court and argument would not aid the decisional process.

DISMISSED.
