Whether Diamond preserved her retaliation claim for de novo district-court review and appellate review after the magistrate judge’s second report and recommendation.
Holding
No. By failing to file a specific written objection to the second report’s treatment of retaliation, Diamond waived appellate review of that claim.
Reasoning
The Federal Magistrates Act and Federal Rule of Civil Procedure 72(b) require a district court to make a de novo determination only of portions of a magistrate judge’s report to which a party makes specific written objections. Without a timely objection, the district court need only assure itself that the report contains no clear error before accepting it.
Diamond had objected to the initial report’s retaliation ruling, but the district court directed the magistrate judge to prepare a new report after supplemental briefing. Although the second report incorrectly said that Diamond had not argued retaliation in her latest memorandum, Diamond did not object to that error or to the report’s resulting treatment of the retaliation claim.
That omission failed to alert the district court that Diamond sought renewed de novo consideration of retaliation. The court therefore could adopt the magistrate judge’s recommendation without de novo review, and Fourth Circuit waiver doctrine barred Diamond from raising the claim on appeal.
