David L. McCullough seeks to appeal the district court's order dismissing this 28 U.S.C. Sec. 2254 action. Appellant's action was referred to a magistrate pursuant to 28 U.S.C. Sec. 636(b)(1)(B). The magistrate recommended that relief be denied and advised appellant that the failure to file timely objections to this recommendation could waive appellate review of a district court order based upon the recommendation. Despite this warning, appellant failed to file timely objections to the magistrate's recommendation.

This Court has held that the timely filing of objections to a magistrate's recommendation is necessary to preserve appellate review of the substance of that recommendation where the parties have been warned that failure to object will waive appellate review. Wright v. Collins, 766 F.2d 841 (4th Cir. 1985); United States v. Schronce, 727 F.2d 91 (4th Cir.), cert. denied, 467 U.S. 1208 (1984). See Thomas v. Arn, 474 U.S. 140 (1985). Appellant has waived appellate review by failing to file timely objections after receiving proper notice. We accordingly deny a certificate of probable cause to appeal and dismiss the appeal. We dispense with oral argument because the dispositive issues recently have been decided authoritatively.

DISMISSED.
