In international law and international relations, a protocol is usually an international treaty or agreement that complements an earlier treaty or international agreement. A protocol may amend the previous contract or add additional provisions. The parties to the previous agreement are not obliged to adopt the protocol. This is sometimes clearer by referring to it as an “optional protocol”, especially when many parties to the first agreement do not support the protocol. Therefore, nations can be very cautious when it comes to qualifying an agreement as a treaty. For example, in the United States, agreements between the United States are pacts and agreements between states and the federal government or between government authorities are declarations of intent. There are three ways to amend an existing treaty. First, a formal amendment requires States parties to go through the ratification process again. The renegotiation of contractual provisions can be lengthy and time-consuming, and often some parties to the original treaty do not become parties to the amended treaty. In determining the legal obligations of States, a party to the original treaty and a party to the amended treaty, States are bound only on the conditions on which they have both agreed. Contracts may also be amended informally by the council of contractual experts if the amendments are only procedural, technical amendments to the international law of usage may also modify a treaty if the conduct of the State demonstrates a new interpretation of the legal obligations under the treaty.
Minor corrections may be made to a contract by a report; However, a record is usually reserved for amendments aimed at correcting manifest errors in the adopted text, i.e. when the adopted text does not correctly reflect the intention of the parties who accept it. . . .
