    UNITED STATES of America, Plaintiff-Appellee, v. Marcus PRESTON, Defendant-Appellant.
    No. 17-7611
    United States Court of Appeals, Fourth Circuit.
    Submitted: February 22, 2018
    Decided: February 27, 2018
    
      Marcus Preston, Appellant Pro Se. Debra Lynn Dwyer , Assistant United States Attorney, OFFICE OF THE UNITED STATES ATTORNEY, Baltimore, Maryland, for Appellee.
    Before TRAXLER and DUNCAN, Circuit Judges, and HAMILTON, Senior Circuit Judge.
   Unpublished opinions are not binding precedent in this circuit.

PER CURIAM:

Marcus Preston seeks to appeal the district court’s order dismissing his 28 U.S.C. § 2255 (2012) motion as successive and unauthorized. 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 ap-pealability 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, 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 Preston 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
