Note 198 — ARTICLE II (continued 2)

Neely v. Henkel, 180 U.S. 109, 121 (1901). A different theory is offered by Justice Story in his opinion for the Court in Prigg v. Pennsylvania, 16 Pet. 539 (1842), in the following words: "Treaties made between the United States and foreign powers, often contain special provisions, which do not execute themselves, but require the interposition of Congress to carry them into effect, and Congress has constantly, in such cases, legislated on the subject; yet, although the power is given to the executive, with the consent of the senate, to make treaties, the power is nowhere in positive terms conferred upon Congress to make laws to carry the stipulations of treaties into effect. It has been supposed to result from the duty of the national government to fulfil all the obligations of treaties." Ibid. 619. Story was here in quest of arguments to prove that Congress had power to enact a fugitive slave law, which he based on its power "to carry into effect rights expressly given and duties expressly enjoined" by the Constitution. Ibid. 618-619. But the treaty-making power is neither a right nor a duty, but one of the powers "vested by this Constitution in the Government of the United States." Article I, section 8, clause 18.
