UNPUBLISHED UNITED STATES COURT OF APPEALS FOR THE FOURTH CIRCUIT No. 15-7917 UNITED STATES OF AMERICA, Plaintiff - Appellee, v. OPIO DIARRA MOORE, a/k/a O, Defendant - Appellant. Appeal from the United States District Court for the District of Maryland, at Greenbelt. Roger W. Titus, Senior District Judge. (8:08-cr-00203-RWT-1; 8:13-cv-03589-RWT) Submitted: May 31, 2016 Decided: June 3, 2016 Before GREGORY, DUNCAN, and WYNN, Circuit Judges. Dismissed by unpublished per curiam opinion. Opio Diarra Moore, Appellant Pro Se. Deborah A. Johnston, Assistant United States Attorney, Greenbelt, Maryland; Michael Richard Pauze, Assistant United States Attorney, Washington, D.C.; Christen Anne Sproule, Assistant United States Attorney, Los Angeles, California, for Appellee. Unpublished opinions are not binding precedent in this circuit. PER CURIAM: Opio Diarra Moore seeks to appeal the district court’s order denying relief on his 28 U.S.C. § 2255 (2012) motion. The order is not appealable unless a circuit justice or judge issues a certificate of appealability. 28 U.S.C. § 2253(c)(1)(B) (2012). 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) (2012). 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 (2000); see Miller-El v. Cockrell, 537 U.S. 322, 336-38 (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. We have independently reviewed the record and conclude that Moore 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 2 contentions are adequately presented in the materials before this court and argument would not aid the decisional process. DISMISSED 3
