Of course, the raw figures must be carefully interpreted. Only a very small minority of all executive agreements were based exclusively on the powers of the President as commander-in-chief and external relations body; The rest was approved in advance by Congress by law or by the provisions of the treaty ratified by the Senate.440 Therefore, consideration of the constitutional significance of executive agreements must begin with a differentiation between the types of agreements that must be classified under this unique title.441 A The treaty is an international agreement concluded in writing between two or more sovereign states and governed by international law. , whether they are used in a single instrument or in two or more related instruments. Treaties have many names: conventions, agreements, pacts, pacts, charters and statutes, among others. The choice of name has no legal value. Contracts can generally be categorized into one of two main categories: bilateral (between two countries) and multilateral (between three or more countries). Unlike the executive contract termination procedure, which has not received much opposition from Congress in the past, constitutional requirements to end Senate-approved ratified treaties have been the subject of occasional debate between the legislature and the executive branch. Some commentators have argued that termination of contracts is comparable to termination of federal laws.197 Since national statutes can only be terminated by the same procedure, in which they were adopted198 – that is, the two houses end in a majority vote and with the signature of the President or a veto – these commentators argue that contracts must also be terminated by a procedure similar to their manufacture , including the legislative branch.199 1904 and 1905 Secretary of State John Hay negotiated a number of contracts for the general arbitration of international disputes. Article II of the Treaty with Great Britain, for example, provided that “in each particular case, the High Contracting Parties enter into a special agreement before being called before the Permanent Court of Arbitration, clearly specifying the issue and the extent of the powers of arbitrators and setting the deadlines for the formation of the arbitration tribunal and the various stages of the proceedings.” 460 The Senate approved the British treaty by a constitutional majority, having first amended it by “agreement” by imposing the word “treaty.” President Theodore Roosevelt, who called “ratification” a rejection, sent the treaties to the archives.
