United States v. United Mine Workers of America, 330 U.S. 258 (1947), was a case in which the United States Supreme Court examined whether a trial court acted appropriately when it issued a restraining order to prevent a labor strike organized by coal miners. In an opinion written by Chief Justice Fred M. Vinson, the Court held that a restraining order and preliminary injunction prohibiting a strike did not violate the Clayton Antitrust Act or the Norris-La Guardia Act, that the trial court was authorized to punish the violation of its orders as criminal contempt,and that fines imposed by the trial court were warranted in the situation.
