United Nations General Assembly
From the UN website: established in 1945 under the Charter of the United Nations, the General Assembly occupies a central position as the chief deliberative, policy-making and representative organ of the United Nations. Comprising all 192 Members of the United Nations, it provides a forum for multilateral discussion of the full spectrum of international issues covered by the Charter. It also plays a significant role in the process of standard-setting and the codification of international law. The Assembly meets in regular session intensively from September to December each year, and thereafter as required.
