Some other nations have similar provisions regarding the ratification of treaties. The Treaty of Versailles (Wilson) is an excellent example. On the other hand, executive agreements are more informal and are not approved by the Senate. It is not a formal law, but it is not binding. SALT I is a good example. In the summer of 1787, the delegates of the Constitutional Convention debated the structure and powers of a new legislative body. One of the questions they asked was: Should the power of contracting be within the legislative or executive branch? According to the articles of Confederation, a treaty could be concluded with the agreement of nine of the thirteen states or two-thirds. Some delegates, such as Charles Pinckney of South Carolina, insisted that the Senate, where each state was represented on an equal footing, had the exclusive power to enter into contracts. .
