Owen J. Roberts, In re National Labor Relations Board…
“ A court has jurisdiction, in another use of the term, to examine the question whether that power is conferred upon it in the circumstances disclosed but if it finds such power is not granted it lacks jurisdiction of the subject matter and must refrain from any adjudication of rights in connection therewith. Since the statute empowers the Board, before the filing of a transcript, to vacate or modify its orders, certainly it does not confer jurisdiction upon the reviewing court to prohibit the exercise of the granted power. ”
