Which of the following elects the judges of International Court of Justice?

Article 4 of the Statute of the International Court of Justice provides that the members of the Court are elected by the General Assembly and by the Security Council; Article 8 requires the two bodies to vote independently, and Article 10 requires an absolute majority in both. The judges are therefore elected by "Both the General Assembly and the Security Council of United Nations". Neither organ acting alone elects a judge, and the Court does not elect its own members.
