Avco Corporation, an employer, brought suit in a
Tennessee court to enjoin the Machinists
union and its members from striking in violation of a no-strike clause in the collective bargaining agreement. The state court issued an
ex parte injunction. The union moved in
federal District Court for removal of the case, and dissolution of the injunction. The District Court ruled that the action was within its
original jurisdiction, denied a motion to remand to the state court, and dissolved the injunction. The
Sixth Circuit Court of Appeals affirmed. ==Supreme Court decision==
