In Waetzig v. Halliburton Energy Services, 2023 U.S. App. LEXIS 23948, — F.4th – (10th Cir. Sept. 11, 2023), the circuit court reversed a district court's order relying on Fed. R. Civ. P. 60(b) to reopen a case that had been voluntarily dismissed without prejudice under Fed. R. Civ. P. 41(a). A split panel held that "a court cannot set aside a voluntary dismissal without prejudice because it is not a final judgment, order or proceeding."
