No. 97-2080.
United States Court of Appeals, Tenth Circuit.
March 16, 1998.

Before ANDERSON, McKAY, and LUCERO, Circuit Judges.


1
ORDER AND JUDGMENT*


2
After examining the briefs and the appellate record, this panel has determined unanimously that oral argument would not materially assist the determination of this appeal.  See Fed.  R.App. P. 34(a);  10th Cir.  R. 34.1.9.  The case is therefore ordered submitted without oral argument.


3
Intervenors-Appellants appeal the district court's dismissal with prejudice of their complaints and the court's award of costs to Plaintiffs-Appellees' counsel.  Because the district court dismissed with prejudice the claims of a party, we exercise jurisdiction pursuant to 28 U.S.C. § 1291.


4
In its dismissal, the district court adopted the magistrate judge's Proposed Findings and Recommendations filed February 10, 1997, without considering Intervenors' objections to those findings and recommendations.  The court determined that Intervenors' objections were untimely filed.  See Appellants' App. at 50-52 (Memorandum Opinion and Order, filed March 7, 1997).  Intervenors contend that the district court erroneously calculated the time for filing objections to the magistrate judge's findings and recommendations, and, therefore, the court failed to conduct the requisite de novo review of those findings and recommendations and Intervenors' objections.  Intervenors then ask this court to address the merits of their intervention claims.  Plaintiffs agree that the district court miscalculated the time to file objections.  However, Plaintiffs argue that the case should be remanded to the district court for de novo review of Intervenors' objections and Plaintiffs' responses to those objections.


5
After reviewing the record, we conclude that the district court erred in calculating the timeliness of Intervenors' objections to the magistrate judge's findings and recommendations under Federal Rule of Civil Procedure 6.  Pursuant to 28 U.S.C. § 636(b)(1), we vacate the district court's Memorandum Opinion and Order and remand the case for the district court's de novo review of the timely filed objections to the magistrate judge's Proposed Findings and Recommendations.  See Northington v. Marin, 102 F.3d 1564, 1570 (10th Cir.1996);  Summers v. Utah, 927 F.2d 1165, 1167-68 (10th Cir.1991).  In view of our ruling, upon remand the case will be in the same posture as it was on the day on which Intervenors' objections were timely filed, February 28, 1997.1


6
REVERSED and REMANDED.



*
 This order and judgment is not binding precedent, except under the doctrines of law of the case, res judicata, and collateral estoppel.  The court generally disfavors the citation of orders and judgments;  nevertheless, an order and judgment may be cited under the terms and conditions of 10th Cir.  R. 36.3


1
 Our review of the applicable Federal Rules of Civil Procedure, the record, and the civil docket indicates that Intervenor A. Gill Dyer timely filed his objections to the magistrate judge's recommended disposition on February 28, 1997.  Those objections were entered into the docket on March 3, 1997.  We have determined that, under Federal Rules of Civil Procedure 5(b) and (6), Intervenors had until March 3, 1997, to timely file objections
