Dismissed by unpublished PER CURIAM opinion. Unpublished opinions are not binding precedent in this circuit. PER CURIAM: Eddie Gamble, Sr., seeks to appeal the district court’s order accepting the recommendation of the magistrate judge, construing his 28 U.S.C. § 2241 (2006) petition as a successive 28 U.S.C.A. § 2255 (West Supp.2012) motion, and dismissing it for lack of jurisdiction. The order is not ap-pealable unless a circuit justice or judge issues a certificate 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 Gamble has not made the requisite showing. Accordingly, we deny a certifícate of appealability, deny leave to proceed in for-ma pauperis, 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. DISMISSED.
