“It is important to bear in mind that we are here dealing not alone with an authority vested in the President by an exertion of legislative power, but with such an authority plus the very delicate, plenary and exclusive power of the President as the sole organ of the federal government in the field of international relations — a power which does not require as a basis for its exercise an act of Congress, but which, of course, exists as long as it is not contravened by any act of Congress.”

Justice George Sutherland
