Decisional StructureDocuments from  to 
Content and Structure
At its entry into force, ESRO inherited the scheme of decisional structure which belonged to COPERS. In that scheme, the making-decisional bodies were a Council, a Technical Committee and a Finance Committee. In 1966, in order to solve the political crisis of ESRO, it was also decided to revise that scheme. A Group, chaired by J.H. Bannier, Director of the Netherlands Organisation for Pure Scientific Research, elaborated a project redefining the roles of the main boards. Between 1968 and 1971, the effects of the reform entered gradually into force. The newly introduced separation between mandatory and optional programmes on programmes on application satellites empowered the Council, in which all the delegates of member states were represented. In the reformed scheme, the Council become the supreme body and new organs, namely the Programme Boards, the subordinate bodies, namely the Finance and Programme Committees, and the advisory groups were set up on the basis of special arrangements or by Council decisions.
