The States parties to the Statute of the Court may "at any time declare that they recognize as compulsory ipso facto and without special agreement, in relation to any other State accepting the same obligation, the jurisdiction of the Court" (Art. 36, para. 2 of the Statute).
Each State which has recognized the compulsory jurisdiction of the Court has in principle the right to bring any one or more other States which has accepted the same obligation before the Court by filing an application instituting proceedings with the Court, and, conversely, it has undertaken to appear before the Court should proceedings be instituted against it by one or more such other States.
The Declarations recognizing the jurisdiction of the Court as compulsory take the form of a unilateral act of the State concerned and are deposited with the Secretary-General of the United Nations.
