Oral Argument: Hain Celestial Group, Inc. v. Palmquist | Forum Fight

Hain Celestial Group, Inc. v. Palmquist | Case No. 24-724 | Oral Argument Date: 11/4/25 | Docket Link: Here Overview Today, the Supreme Court hears oral arguments in Hain Celestial Group versus Palmquist, a forum fight about when courts keep cases they never should have had. A Texas family sued two companies over their child's heavy metal poisoning from baby food—but after a federal court wrongly kicked out one defendant and ran a two-week trial, an appeals court said the case never belonged in federal court, forcing everyone back to square one. Questions 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. 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.
