Youngstown Sheet & Tube Co. v. Sawyer · ¶63

Apart from his vast share of responsibility for the conduct of our foreign relations, the embracing function of the President is that "he shall take Care that the Laws be faithfully executed ... Art. II, § 3. The nature of that authority has for me been comprehensively indicated by Mr. Justice Holmes. “The duty of the President to see that the laws be executed is a duty that does not go beyond the laws or require him to achieve more than Congress sees fit to leave within his power.” Myers v. United States, 272 U. S. 52, 177. The powers of the President are not as particularized as are those of Congress. But unenumerated powers do not mean undefined powers. The separation of powers built into our Constitution gives essential content to undefined provisions in the frame of our government.
