The International Court of Justice ('ICJ') is termed as the main judicial branch of the United Nations. In 1946, the General Assembly of the United Nations, enacted the Statute of the ICJ which gave rise to the institution of the International Court of Justice at The Hague, Netherlands. All members of the UN are party to this statute, by default owing to Article 93 of the United Nations Charter, and non-members may also become parties under this Article.
