No. 87-7289.
United States Court of Appeals, Fourth Circuit.
April 25, 1988.

James M. Minniefield-El, appellant pro se.
Before DONALD RUSSELL, K.K. HALL, and SPROUSE, Circuit Judges.
PER CURIAM:


1
James M. Minniefield-El appeals the district court's order dismissing this 42 U.S.C. Sec. 1983 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 object to the magistrate's recommendation.*


2
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 objections after receiving proper notice.  We accordingly affirm the judgment of the district court.  We dispense with oral argument because the dispositive issues recently have been decided authoritatively.


3
AFFIRMED.



*
 Even assuming that Minniefield-El's opposition to the defendants' motion to dismiss could be construed as an objection to the magistrate's recommendation, the action was properly dismissed as barred under the doctrine of res judicata
