National Implementation Measures
Upon ratification by a State Signatory, the Comprehensive Nuclear-Test-Ban Treaty (CTBT) will not automatically become a part of the State's domestic law, unless the law of that State so provides. For the treaty to be applicable domestically, the appropriate national implementation measures will have to be taken in accordance with a State's constitutional procedures either at the time of ratification or immediately following ratification. National implementation measures are therefore an indispensable step in fulfilling a State's obligations under the CTBT, even in advance of its entry into force.   more
