In Haver v. Yaker, the Supreme Court declares that because treaties are the law of the land, the Senate has the right to amend a treaty like any other law, rather than simply adopting or rejecting it as a whole. Amendments that change the wording of a treaty require only a simple majority vote. The Senate can also pass reservations that indicate a change in interpretation of the treaty. Such adjustments help senators build the coalitions needed to gain a two-thirds vote for ratification.
