the general debate, Member States are given the opportunity to raise attention to topics or issues that they feel are important. In addition to the general debate, there are also many other high-level thematic meetings, summits and informal events held during general debate week. The General debate is held in the United Nations General Assembly Hall at the United Nations Headquarters in New York. Special sessions Special sessions, or UNGASS, may be convened in three different ways, at the request of the Security Council, at the request of a majority of United Nations members States or by a single member, as long as a majority concurs. Special sessions typically cover one single topic and end with the adoption of one or two outcome documents, such as a political declaration, action plan or strategy to combat said topic. They are also typically high-level events with participation from heads of state and government, as well as by government ministers. There have been 30 special sessions in the history of the United Nations. Emergency special sessions If the Security Council is unable, usually due to disagreement among the permanent members, to come to a decision on a threat to international peace and security, then emergency special sessions can be convened in order to make appropriate recommendations to Members States for collective measures. This power was given to the Assembly in Resolution 377(V) of 3 November 1950. Emergency special sessions can be called by the Security Council, if supported by at least seven members, or by a majority of Member States of the United Nations. If enough votes are had, the Assembly must meet within 24 hours, with Members being notified at least twelve hours before the opening of the session. There have been 11 emergency special sessions in the history of the United Nations.
