"When a district court orders a remand to the plan administrator, it retains jurisdiction over the case while the administrator reconsiders the claim. The first panel should have vacated the district court's judgment in favor of Principal and remanded the case to the district court with instructions that it remand the case to Principal. Because the first panel remanded the matter to Principal, the district court erroneously determined that it had nothing else to do.... The district court did have jurisdiction over Card's motions for fees and to reopen the case." [Card v. Principal Life Ins. Co., No. 20-6217 (6th Cir. Nov. 2, 2021)]
