The deliberative body of the public establishment of inter-municipal cooperation meets at least once every three months or, for unions formed for a single work or service of inter-municipal interest, once every six months. To this end, the chairman convenes the members of the deliberative body. The deliberative body meets at the headquarters of the public establishment of inter-municipal cooperation or at a location chosen by the deliberative body in one of the member municipalities.
At the request of five members or the chairman, the deliberative body may decide, without debate, by an absolute majority of its members present or represented, that it meets in camera.
