¶1*242 Unpublished opinions are not binding precedent in this circuit.
¶2 Rafael Garcia Olvera seeks to appeal the district court’s order denying relief on his 28 U.S.C. § 2255 (2012) motion. The district court referred this case to a magistrate judge pursuant to 28 U.S.C. § 636(b)(1)(B) (2012). The magistrate judge recommended that relief be denied and advised Olvera that the failure to file timely objections to this recommendation could waive appellate review of a district court order based upon the recommendation.
¶3 The timely filing of specific objections to a magistrate judge’s recommendation is necessary to preserve appellate review of the substance of that recommendation when the parties have been warned of the consequences of noncompliance. Wright v. Collins, 766 F.2d 841, 845-46 (4th Cir. 1985); see also Thomas v. Arn, 474 U.S. 140, 106 S.Ct. 466, 88 L.Ed.2d 435 (1985). Olvera has waived appellate review by failing to file specific objections after receiving proper notice. Accordingly, we deny a certificate of appealability and dismiss the appeal.
¶4 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.
