What are the most important ICJ cases?

The International Court of Justice (ICJ) is the principal judicial organ of the United Nations, and it settles legal disputes between states and gives advisory opinions on legal questions. Since its creation in 1946, the ICJ has dealt with 192 cases, covering a wide range of issues such as territorial disputes, maritime boundaries, human rights, environmental protection, and more.

Some of the most important ICJ cases are:

Corfu Channel (United Kingdom v. Albania): The first case entered in the General List of the Court, concerning the responsibility of Albania for the damage caused by mines to British warships in the Corfu Channel in 1946. The Court affirmed the principle of freedom of navigation and the obligation of states to notify other states of any dangers to navigation in their waters.

South West Africa (Ethiopia v. South Africa; Liberia v. South Africa): A series of cases concerning the administration of South West Africa (now Namibia) by South Africa under a mandate of the League of Nations. The Court rejected the claims of Ethiopia and Liberia that South Africa had violated its obligations under the mandate, but also declared that South Africa had no right to establish apartheid in the territory.

Barcelona Traction (Belgium v. Spain): A case concerning the protection of Belgian shareholders in a Canadian company that operated electric power plants in Spain. The Court held that only the state of nationality of a company can exercise diplomatic protection on behalf of the company, and that shareholders cannot claim such protection for themselves.

Nuclear Tests (Australia v. France; New Zealand v. France): Two cases concerning the legality of atmospheric nuclear tests conducted by France in the South Pacific. The Court found that France had violated its obligations under international law by not informing and consulting other states affected by the tests, but also held that France had given a legally binding undertaking to cease such tests.

East Timor (Portugal v. Australia): A case concerning the validity of a treaty between Australia and Indonesia on the delimitation of the continental shelf in an area that included East Timor, then under Indonesian occupation. The Court held that it could not rule on the case without affecting the rights and interests of Indonesia, which was not a party to the proceedings.

Legal Consequences of the Construction of a Wall in the Occupied Palestinian Territory: An advisory opinion requested by the UN General Assembly on the legal consequences arising from the construction of a wall by Israel in the occupied Palestinian territory. The Court found that the wall violated international law and that Israel had an obligation to cease its construction, dismantle it, and make reparation for the damage caused.

Whaling in the Antarctic (Australia v. Japan; New Zealand intervening): A case concerning Japan’s whaling program in the Antarctic, which Japan claimed was for scientific purposes. The Court held that Japan had not acted in conformity with its obligations under the International Convention for the Regulation of Whaling, and that it should revoke its permits and refrain from granting any further ones.
