"On March 15, 2006, the U.N. General Assembly passed a resolution replacing the Commission on Human Rights with a new Human Rights Council (the Council). The U.N. Secretariat and some governments, including the United States, view the establishment of the Council as a key component of comprehensive U.N. reform. The Council was designed to be an improvement over the Commission, which was widely criticized for the composition of its membership when perceived human rights abusers were elected as members. The General Assembly resolution creating the Council, among other things, increased the number of meetings per year and introduced a 'universal periodic review' process to assess each member state's fulfillment of its human rights obligations."
