Unpublished opinions are not binding precedent in this circuit.

Bobby Eugene Crews appeals the district court’s order treating his Fed. R. Civ. P. 60(b) motion as a successive 28 U.S.C. § 2255 (2012) motion, and denying it on that basis. * On appeal, we confine our review to the issues raised in the Appellant’s brief. See 4th Cir. R. 34(b). Because Crews’ informal brief does not challenge *158 the basis for the district court’s dispositive procedural ruling, Crews has forfeited appellate review of the court’s order. See Williams v. Giant Food Inc., 370 F.3d 423, 430 n.4 (4th Cir. 2004). Accordingly, we affirm the district court’s judgment. See United States v. McRae, 793 F.3d 392, 400 (4th Cir. 2015).

Additionally, we construe Crews’ notice of appeal and informal brief as an application to file a successive § 2255 motion. United States v. Winestock, 340 F.3d 200, 208 (4th Cir. 2003). In order to obtain authorization to file a successive § 2255 motion, a prisoner must assert claims based on either:

(1) newly discovered evidence that .., would be sufficient to establish by clear and convincing evidence that no reasonable factfinder would have found the movant guilty of the offense; or

(2) a new rule of constitutional law, made retroactive to cases on collateral review by the Supreme Court, that was previously unavailable.

28 U.S.C. § 2255(h). Crews’ claim does not satisfy either of these criteria. Therefore, we deny authorization to file a successive § 2255 motion.

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.
