How can a state sue in the icj?

A state can sue another state in the International Court of Justice (ICJ) if both states have accepted the court's jurisdiction, typically through a treaty or by mutual consent. The suing state must submit a written application outlining the legal basis for the claim and the facts of the case. The ICJ will then determine whether it has jurisdiction to hear the case before proceeding with the merits of the dispute. Only states can be parties in cases before the ICJ, as it does not hear cases brought by individuals or organizations.
