They are all based at UN Headquarters in New York City, with the exception of the International Court of Justice, which is located at The Hague, Netherlands. The UN and its specialized agencies constitute the UN system. The General Assembly, thought by some to be the nearest thing to a world parliament, is the main deliberative body. All 185 Member States are represented in it, and each has a vote. Decisions on ordinary matters are taken by simple majority.
Important questions require a two-thirds majority.
Special or emergency sessions are held when necessary. When the Assembly is not in session, its work goes on through special committees and bodies. The Assembly has the right to discuss and make recommendations on all matters within the scope of the UN Charter, i.e., the organization's founding document. It does not have the power to force any government into action, but its recommendations are meant to carry the weight of world opinion. The GA also sets policies and determines programmes for the UN Secretariat, directs activities for development, and approves the UN budget which includes peacekeeping operations.
