Description: Hain Celestial Group, Inc. v. Palmquist | Case No. 24-724 | Oral Argument Date: 11/4/25 | Docket Link: HereQuestion Presented: Whether a district court's final judgment as to completely diverse parties must be vacated when an appellate court later determines that it erred by dismissing a non-diverse party at the time of removal; and whether a plaintiff may defeat diversity jurisdiction after removal by amending the complaint to add factual allegations that state a colorable claim against a nondiverse party when the complaint at the time of removal did not state such a claim.OverviewThis episode examines a technical but consequential case about federal court jurisdiction that could affect thousands of removal cases nationwide.
