The International Court of Justice (known colloquially as the World Court or ICJ) is the principal judicial organ of the United Nations. Its seat is in the Peace Palace at The Hague, Netherlands. Established in 1945 by the Charter of the United Nations, the Court began work in 1946 as the successor to the Permanent Court of International Justice. The Statute of the International Court of Justice, similar to that of its predecessor, is the main constitutional document constituting and regulating the Court. The ICJ should not be confused with the International Criminal Court or a court exercising jurisdiction under Belgium's War Crimes Law, both of which also potentially have "global" jurisdiction. English and French are its two official languages.
The Court's workload is characterised by a wide range of judicial activity. Its main functions are to settle legal disputes submitted to it by states and to give advisory opinions on legal questions submitted to it by duly authorised international organs and agencies. The number of decisions made by the ICJ has been relatively small, but there has clearly been an increased willingness to use the Court since the 1980s, especially among developing countries, although the USA withdrew from compulsory jurisdiction in 1986, meaning it accepts the court's jurisdiction on only a case-to-case basis.
