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, minutes are generally reserved for amendments aimed at correcting obvious errors in the adopted text, i.e. when the adopted text does not adequately reflect the intention of the parties who accept it. In addition to treaties, there are other, less formal international agreements. These include efforts such as the Proliferation Security Initiative (PSI) and the G7 Global Partnership Against the Spread of Mass Destruction. . . .
