In Waetzig v. Halliburton Energy Services, 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.”
