The Hain Celestial Group, Inc. v. Palmquist

Issue: (1) 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 (2) whether a plaintiff may defeat diversity jurisdiction after removal by amending the complaint to add factual allegations that state a colorable claim against a non-diverse party when the complaint at the time of removal did not state such a claim.
