Preparation of an International Bill of Rights was a fundamental preoccupation of the United Nations. The Charter of the United Nations, agreed to in San Francisco in 1945, in seven different articles declared United Nations support for human rights and set up a Human Rights Commission. In its first session in January 1946, the General Assembly called for the Commission to work towards "the formulation of an international bill of rights". When the Commission on Human Rights began its work in February 1947, this item was its first priority. The members of the Commission were immediately divided over whether the Bill should take the form of a proclamation or a treaty. As a compromise, they decided that the Bill should have three parts: a declaration proclaiming general principles, a "covenant or covenants" embodying these principles in a form which would be binding on States which ratified them, and "measures of implementation" or provisions for review of the way in which States carried out their covenant obligations. In less than two years, the Commission sent to its superior bodies, the Economic and Social Council and the General Assembly, a completed draft of a Universal Declaration of Human Rights. On 10 December 1948, the General Assembly adopted the Universal Declaration of Human Rights by a vote of 48 in favour, eight abstentions and no dissensions. The same day, the Assembly adopted resolution urging that the Commission continue giving priority to drafting a treaty which would give legal force to the Declaration. In 1951, the Commission produced a draft covenant which it sent to its parent body, the Economic and Social Council.
