A few months later (in October 1975), he was elected by the General Assembly and the Security Council of the United Nations to the International Court of Justice at The Hague. In 1979, he was elected Vice-President by his colleagues on that Court. In 1981, after the death of Sir Humphrey Waldock, the President of the Court, he took over as Acting President. In 1982, the members of the Court elected him President of the Court. He thus became the first African jurist to hold that honour. Five years later, Elias was also appointed to the Permanent Court of Arbitration at The Hague.
