The ICJ is one of the principal organs of the UN. Located in The Hague (La Haye), the ICJ is the judicial arm of the organization. The previous Permanent Court of International Justice (PCIJ) formed the institutional foundations of the ICJ. Nevertheless, there are significant differences between the two courts. First, even though their statutes are identical, unlike the PCIJ, the Statute of the ICJ is integral to the UN Charter. Second, whereas the PCIJ and its membership were independent of the League, all UN members are automatically parties to the Statute of the ICJ. The ICJ consists of fifteen judges co-elected bythe General Assembly and Security Council for a nine-year term. One-third of the judges are elected every three years, and they may be reelected.Judges must possess the qualifications required for appointment to the highest judicial institutions in their home country or must show competence in international law. Each judge must have a different nationality; together they represent the major legal systems of the world.
