Background
The International Court of Justice (ICJ) is composed of 15 judges elected to nine-year terms of office.
The UN General Assembly and the Security Council vote simultaneously but separately, and a candidate must receive an absolute majority in both bodies.
One third of the Court is elected every three years, and judges are eligible for re-election.
The Court may not include more than one national of the same State.
The judges elect a President and a Vice-President to hold office for three years.
The Court has its seat in The Hague and is the principal judicial organ of the United Nations.
In plain words
Absolute majority More than half — A candidate needs more than half of the votes in both the General Assembly and the Security Council.
Principal judicial organ Main court of the UN — The ICJ is the main judicial body of the United Nations.
Permanent Court of Arbitration Hague-based arbitration body — Groups of its members nominate candidates for the Court's elections.
