The power to make treaties with other nations is an inherent attribute of the sovereign power of an independent nation.

Where the treaty-making power is exercised by the sovereign power of a nation, the right to treat with other nations rests wholly in sovereignty and extends to every question pertaining to international relations.

Where, however, the treaty-making power is not exercised by the sovereign power of the nation as a whole, but has been delegated to a branch of the government by which it is exercised in a representative capacity, the treaty-making power there, although it arises from sovereignty, rests in grant, and can be exercised only to the extent of and in accordance with the terms fixed by the grant.

So in the United States, where the people, as the sovereign power, have delegated through the medium of their State conventions or State legislatures the treaty-making power to a designated section of the Federal Government under the Constitution, such power rests in grant and is to be measured and exercised under the terms of such grant.
