Most of the treaties submitted to the Senate received the advice of the Senate and approved ratification. In the first 200 years, the Senate approved more than 1,500 contracts and rejected only 21. Some of them, including the Treaty of Versaille, were rejected twice. Most of the time, the Senate simply did not vote on contracts that its management considered insufficient in the Senate to get approval, and in general, those contracts were eventually withdrawn. At least 85 contracts were eventually withdrawn because the Senate had never taken any definitive action against them. Contracts can also remain on the Senate Committee on Foreign Relations for a long time, as treaties must not be res submitted at the beginning of each new congress. There have been cases where contracts have been dormant in committee for years, if not decades, without action being taken. The Case-Zablocki Act of 1972 requires the President to notify the Senate within 60 days of an executive agreement. The president`s powers to conclude such agreements have not been restricted. The reporting requirement allowed Congress to vote in favor of repealing an executive agreement or to refuse funding for its implementation.  The Constitution provides for the Senate to exercise its “consultation and approval” in drafting contracts, an ambiguous term that presidents and senators have discussed since the founding of the country.
During the War of 1812, Delaware Senator James Bayard was a member of the delegation to negotiate the Treaty of Gant. His presence raised the question of whether the senators on the negotiating team would encourage the Senate to approve the treaty or whether it would violate the separation of powers. This debate has been going on for generations without resolution. Executive agreement, an agreement between the United States and a foreign government that is less formal than a treaty and is not subject to the constitutional requirement for ratification by two-thirds of the U.S. Senate. The U.S. Constitution does not explicitly give a president the power to enter into executive agreements. However, it may be authorized to do so by Congress or may do so on the basis of its foreign relations management authority. Despite questions about the constitutionality of executive agreements, the Supreme Court ruled in 1937 that they had the same force as treaties. As executive agreements are made on the authority of the president-in-office, they do not necessarily bind his successors. The U.S.
Supreme Court Pink (1942) found that international agreements, which were concluded in law, have the same legal status as treaties and do not require Senate approval. To Reid v. Concealed (1957), the Tribunal, while reaffirming the President`s ability to enter into executive agreements, found that such agreements could not be contrary to existing federal law or the Constitution.
