International Court of Justice

General Overview

Established in 1945 by the Charter of the United Nations, the International Court of Justice (ICJ) is the principal judicial organ of the United Nations.  The Statute of the International Court of Justice, creating the court and outlining its responsibilities, is annexed to the U.N. Charter. The ICJ's primary role is to settle legal disputes submitted to it by member states and to give advisory opinions on legal questions referred to it by the United Nations and other specialized agencies.

The ICJ has 15 judges elected for nine year nonrenewable terms in office.

The ICJ has two distinct types of jurisdiction: contentious jurisdiction and advisory jurisdiction. The following chart provides a brief overview of each type of jurisdiction and example cases:

Contentious Jurisdiction

There are three ways that states can accept the Court's jurisdiction:

Advisory Jurisdiction

Under Article 65(1), the Court may also give advisory opinions on any legal question brought to it by a U.N. organ or a specialized agency of the U.N. States and individuals have no standing to request advisory opinions. 

As an example of this type of jurisdiction, you can review the General Assembly's 2017 request for the court to render an opinion on the legality and consequences of the United Kingdom's 1968 decolonization of Mauritius. See G.A. Res. 71/292 (June 22, 2017).

The United States originally accepted the Court's compulsory jurisdiction under Article 36(2) with a number of reservations. This acceptance was terminated in 1985 and was prompted by the U.S. government's dissatisfaction with the Court's decision in Military and Paramilitary Activities in and against Nicaragua (Nicaragua v. United States), 1986 I.C.J. 14.
