PER CURIAM:

            Gratiniano       Castillo         seeks       to    appeal        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 dismissing it on

that    basis.      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 Castillo has not made the requisite showing.                              Accordingly,

we deny a certificate of appealability and dismiss the appeal.

            Additionally, we construe Castillo’s notice of appeal

and    informal    brief    as     an    application           to     file    a     second    or

                                              2
successive § 2255 motion.        United States v. Winestock, 

, 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) (2012).         Castillo’s claims do 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.
