Unpublished opinions are not binding precedent in this circuit.

Leon Parrish Marshall appeals the district court’s order construing his Fed. R. Civ. P. 60(b) motion as an unauthorized successive 28 U.S.C. § 2264 (2012) petition, and denying it on that basis. We have reviewed the record and conclude that the district court correctly determined that Marshall’s motion was not a “true 60(b) motion” but was, in substance, a successive § 2254 motion. See United States v. McRae, 793 F.3d 392, 397-400 (4th Cir. 2015). We note that Marshall is not required to obtain a certificate of appealability to appeal the district court’s order, see McRae, 793 F.3d at 400, and we conclude that the district court correctly determined that, in the absence of prefiling authorization, it lacked jurisdiction to consider the successive § 2254 motion, see 28 U.S.C. § 2244(b)(3) (2012). Accordingly, although we grant leave to proceed in forma pau-peris, we affirm the district court’s judgment.

Consistent with our decision in United States v. Winestock, 340 F.3d 200, 208 (4th Cir. 2003), we construe Marshall’s notice of appeal and informal brief as an application to file a second or successive § 2254 petition. In order to obtain authorization to file a successive § 2254 petition, a prisoner must assert claims based on either: (1) a new, previously unavailable rule of constitutional law made retroactive by the Supreme Court to cases on collateral review; or (2) newly discovered evidence, not previously discoverable by due diligence, that would establish by clear and convincing evidence that, but for constitutional error, no reasonable factfinder would have found the petitioner guilty of the offense. 28 U.S.C. § 2244(b)(2). Marshall’s claims fail to satisfy either of these criteria. We therefore deny authorization to file a successive § 2254 petition.

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.
