Created by the Charter of the United Nations, the International Court of Justice (ICJ) is the only world-wide tribunal -- its jurisdiction extending to all states, whether or not they are members of the United Nations. Non-members can be parties before the Court if they accept its jurisdiction. The Court publishes its decisions first in advance-sheet form and later in two annual collections. These are also available online.
