United Nations Security Council Resolution 129
United Nations Security Council resolution 129, adopted unanimously on August 7, 1958, called an emergency special session of the General Assembly. The resolution states that this was as a result of the lack of unanimity of its permanent members at the council's 834th and 837th meetings which prevented it from exercising its primary responsibility for the maintenance of international peace and security.
