Dismissed by unpublished PER CURIAM opinion.

Unpublished opinions are not binding precedent in this circuit.

James W. Bailey, Jr., seeks to appeal the district court’s orders denying his prejudgment motion to compel and denying relief on his 28 U.S.C. § 2255 (2012) motion. This court may exercise jurisdiction only over final orders, 28 U.S.C. § 1291 (2012), and certain interlocutory and collateral orders, 28 U.S.C. § 1292 (2012); Fed. R.Civ.P. 54(b); Cohen v. Beneficial Indus. Loan Corp., 337 U.S. 541, 545-46, 69 S.Ct. 1221, 93 L.Ed. 1528 (1949). The order denying Bailey’s motion to compel is neither a final order nor an appealable interlocutory or collateral order, nor is it ap-pealable under the cumulative judgment rule. See In re Bryson, 406 F.3d 284, 288 (4th Cir. 2005). Accordingly, we dismiss Case No. 15-6863 for lack of jurisdiction.

The order denying Bailey’s § 2255 motion is not appealable unless a circuit justice or judge issues a certificate of appeal-ability. 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, 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 constitu *268 tional right. Slack, 529 U.S. at 484-85, 120 S.Ct. 1595.

We have independently reviewed the record and conclude that Bailey has not made the requisite showing. Accordingly, we deny a certificate of appealability and dismiss Case No. 15-7197. 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.
