Felix Frankfurter

“ The power to stay proceedings in another court appertains distinctively to equity in the enforcement of equitable principles, and the grant or refusal of such a stay by a court of equity of proceedings at law is a grant or refusal of an injunction within the meaning of section 129, as amended. ”

“ A layman may see no difference between the postponement by a trial judge of an action at law, and the postponement of such an action by an equitable proceeding resulting in an interlocutory injunction. ”

“ Chief Justice Hughes for the Court, '* * * contemplates interlocutory orders or decrees which constitute an exercise of equitable jurisdiction in granting or refusing an injunction, as distinguished from a mere stay of proceedings which a court of law, as well as a court of equity, may grant in a cause pending before it by virtue of its inherent power to control the progress of the cause so as to maintain the orderly processes of justice. ”
