Potter Stewart,

“ The judicial contempt power is a potent weapon. When it is founded upon a decree too vague to be understood, it can be a deadly one. Congress responded to that danger by requiring that a federal court frame its orders so that those who must obey them will know what the court intends to require and what it means to forbid. Because the decree of this District Court was not so framed, it cannot stand. And with it must fall the District Court's decision holding the union in contempt. ”
