At the decision making level (the "Legislative" in the ESRO jargon), the supreme governing body was the Council, made of delegations from its Member States. Each member state had one vote in the Council, where it could be represented by not more than two delegates, one of whom was generally a scientist, the other an important national science administrator. One or more advisers were usually included national delegations. The main tasks of the Council were to determine the Organisation's scientific, technical and administrative policy; to approve its programme and annual work plans; and to determine its level of resources both annually, and every third year for the subsequent three-year period. The Council was advised by two subordinate bodies, the Administrative and Finance Committee (AFC) and the Scientific and Technical Committee (STC).
