The main organ between the congresses is the central committee, which is elected in the congresses under a proposal of the retiring central committee. This proposal may only be made after a long period of hearing the lower structures in order to include in it the names they propose. The CC may not change the orientation present in the congress' theses. The main task of the central committee is to define the guidelines of the party's political work and decide the immediate tasks of the party, assuring that the lower structures comply with those decisions. The CC elects, from its members, its Political Bureau, its , and also the Central Commission of Control. This last must assure the compliance between the Party's activities and the statutes, and control the Party's finances. The CC may, or may not, elect the party's secretary-general from its members.
