dealt with by the First Committee, as well as with decolonization The Fifth Committee: Administrative and Budgetary deals with the administration and budget of the United Nations The Sixth Committee: Legal deals with legal matters The roles of many of the main committees have changed over time. Until the late 1970s, the First Committee was the Political and Security Committee (POLISEC) and there was also a sufficient number of additional "political" matters that an additional, unnumbered main committee, called the Special Political Committee, also sat. The Fourth Committee formerly handled Trusteeship and Decolonization matters. With the decreasing number of such matters to be addressed as the trust territories attained independence and the decolonization movement progressed, the functions of the Special Political Committee were merged into the Fourth Committee during the 1990s. Each main committee consists of all the members of the General Assembly. Each elects a chairman, three vice chairmen, and a rapporteur at the outset of each regular General Assembly session. Other committees These are not numbered. According to the General Assembly website, the most important are: Credentials CommitteeThis committee is charged with ensuring that the diplomatic credentials of all UN representatives are in order. The Credentials Committee consists of nine Member States elected early in each regular General Assembly session. General CommitteeThis is a supervisory committee entrusted with ensuring that the whole meeting of the Assembly goes smoothly. The General Committee consists of the president and vice presidents of the current General Assembly session and the chairman of each of the six Main Committees.
