The International Court of Justice is the principal judicial organ of the United Nations. It is composed of 15 judges, elected by the General Assembly and the Security Council. The Court has a twofold role: first, to settle, in accordance with international law, through judgments which have binding force and are without appeal for the parties concerned, legal disputes submitted to it by States; and, second, to give advisory opinions on legal questions referred to it by duly authorized United Nations organs and specialized agencies. The Court is the only principal organ of the United Nations not serviced by the Secretariat and has its own Registry, which provides judicial support to the Court and acts as a permanent administrative organ. The Registry is headed by a Registrar, elected by the Court. The incumbent is appointed by the Court upon the recommendation of the Registrar (Rules of Court, Art. 25). The position is located in the Registry's Information Department. The incumbent reports directly to the Head of the Department.
