International Court of Justice (ICJ).
The International Court of Justice is the primary judicial branch of the United Nations. Its role is to settle legal disputes that cannot be resolved at the national level, as well as to provide advisory opinions on legal matters submitted to it by UN organisations for consideration. Being composed of fifteen judges from different states, the composition of the ICJ is geographically diverse. Although the power of the Court to act on pressing issues is seen as insufficient by many people, the UN Security Council is able to enforce rulings of the ICJ under the provisions of the United Nations Charter. However, the use of vetoes on the Security Council has led to difficulties in the implementation of the rulings of the ICJ, most notably in the famous Nicaragua v. United States case.
