“To be sure, the order on appeal is the district court’s order denying Doe’s motion to re-open the case and sever the cost-splitting provision of the arbitration agreement—not its order compelling arbitration. But that makes no difference for our purposes. As both parties acknowledge, Doe’s motion to re-open and sever was, in effect, nothing more than a motion to reconsider the merits of part of the district court’s order compelling arbitration. And we have no more jurisdiction to review an order declining to reconsider an order compelling arbitration than we do to review the order compelling arbitration itself.” Doe v. Tonti Mgmnt. Co., No. 21-30295 (Jan. 31, 2022).
