The International Court of Justice (ICJ)
The ICJ is the principal judicial organ of the United Nations. It was established and began delivering judgments, orders and advisory opinions in 1946. The ICJ has a twofold role: to settle, in accordance with international law, legal disputes submitted to it by States (Contentious cases ) and to give advisory opinions (Advisory proceedings) on legal questions referred to it by duly authorised United Nations organs and specialised agencies.
ICJ decisions, orders and opinions
Unreported decisions - all decisions from 1946 to the present are available in full text on the ICJ's Cases database on the official ICJ website (open access)
Note: unreported decisions appear much faster than the reported version, with the reported version currently being published about two years after the date of the decisions. Unreported decisions and opinions typically appear within weeks of the decision on the ICJ's decision database.
The Permanent Court of International Justice (PCIJ)
The PCIJ was the predecessor of the International Court of Justice. It held its inaugural sitting in 1922 and was dissolved in 1946. The work of the PCIJ, the first permanent international tribunal with general jurisdiction, made possible the clarification of a number of aspects of international law, and contributed to its development. Between 1922 and 1940 the PCIJ dealt with 29 contentious cases between States, and delivered 27 advisory opinions.
