The headquarter of the International Court of Justice is at :

Geneva
Hague
Rome
Vienna

The correct answer is: The headquarter of the International Court of Justice is at The Hague, Netherlands.

The International Court of Justice (ICJ) is the principal judicial organ of the United Nations (UN). It was established in 1945 by the UN Charter and began work in 1946. The ICJ is located in the Peace Palace in The Hague, Netherlands.

The ICJ is composed of 15 judges, who are elected by the UN General Assembly and the UN Security Council. The judges serve for nine-year terms and are eligible for re-election. The ICJ is the principal judicial organ of the UN and has jurisdiction to settle legal disputes between states. It also has jurisdiction to give advisory opinions on legal questions referred to it by UN organs and specialized agencies.

The ICJ is an independent court and its decisions are binding on the parties to the dispute. The ICJ has a unique role in the international legal system and plays an important role in the peaceful settlement of disputes between states.

The other options are incorrect because:

  • Geneva is the headquarters of the World Health Organization (WHO).
  • Rome is the capital of Italy and the seat of the government of Italy.
  • Vienna is the capital of Austria and the seat of many international organizations, including the United Nations Office at Vienna (UNOV).
