The U.S. Court of Appeals for the Third Circuit doesn't have the authority to review a district court's denial of a motion to reconsider after a case has been remanded to state court, the appeals court has ruled in a case involving a plane crash.

Allowing itself to review a motion to reconsider remand would contradict the principal purpose of the federal rule protecting state jurisdiction over cases that have been remanded, the three-judge panel explained in an opinion that settled an open question of law.
