Demetrious Adonis Moore, Appellant Pro Se.


Unpublished opinions are not binding precedent in this circuit.
PER CURIAM:

       Demetrious Adonis Moore seeks to appeal the district court’s order denying his

Fed. R. Civ. P. 60(b)(6) motion seeking relief from its prior order denying 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, 

, 484 (2000); see Miller-El v. Cockrell, 

,

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. 

.

       We have independently reviewed the record and conclude that Moore has not

made the requisite showing. Although Moore contended that his Rule 60(b) motion was

a “true” Rule 60(b) motion, the motion effectively “attack[ed] the substance of the

[district] court’s resolution of a [§ 2255] claim on the merits,” and thus was the functional

equivalent of a successive § 2255 motion. United States v. McRae, 

, 397

(4th Cir. 2015) (internal quotation marks omitted); see Gonzalez v. Crosby, 

,

531-32 (2005) (distinguishing between true Rule 60(b) motion and unauthorized

successive habeas corpus petition); United States v. Winestock, 

, 207 (4th

                                             2
Cir. 2003) (same). In the absence of prefiling authorization from this court, the district

court lacked jurisdiction to consider a successive § 2255 motion.         See 28 U.S.C.

§ 2244(b)(3) (2012).

      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
