“_Resolved_, That the notice which has been given by the President to Denmark, pursuant to the resolution of the Senate of the 3d of March, 1855, to terminate the treaty with that power of the 26th of April in the year 1826, is sufficient to cause such treaty to terminate and be annulled to all intents whatsoever, pursuant to the eleventh article thereof, and that no other or further act of legislation is necessary to put an end to said treaty, as part of the law of the land.” This was considered May 8th, 1856, when Mr. Sumner spoke as follows. Mr. President,--As this subject was originally brought before the Senate on my motion, I hope to be indulged while I state briefly what seems to be the true state of the question. By the usage of most countries, the war-making power, the treaty-making power, and the treaty-abrogating power are all lodged in one and the same body. For instance, in England, the Queen in council declares war, makes treaties, and also abrogates treaties: so also do the other sovereigns of Europe. This is the growth of custom, and has become European constitutional law. But it is otherwise in the United States, where, according to the Constitution, the war-making power is expressly lodged in Congress, while the treaty-making power is expressly lodged in the President, acting with the advice of two thirds of the Senate. Nothing express appears in the Constitution with regard to the treaty-abrogating power. We are left to argument and inference, in order to ascertain whether this great attribute belongs with the war-making power to Congress, or with the treaty-making power to the President and Senate. To me there are three considerations, each of which seems to be decisive, while the three combined compel us irresistibly to the true conclusion. _First._ In the absence of any express words in the Constitution, the power to abrogate treaties should not be attributed to any _mere fraction_ of the Government, as to the President, or to the President and Senate, nor to any branches short of the whole Government embodied in an Act of Congress. In view of the magnitude of the power, I am at a loss to see how any other conclusion can be adopted on this point. _Secondly._ The Constitution has expressly lodged the war-making power in Congress, and, in doing so, seems by implication to have placed the treaty-abrogating power in the same body; for the latter seems to be an incident of the former. The abrogation of a treaty may be the prelude of war; indeed, it may practically amount to a declaration of war. The powers, though differing in degree, are kindred in character, and should go together.
