The CC was not a permanent institution. It convened plenary sessions, one emergency session, four CC plenary sessions and six joint CC–Central Control Commission (CCC) plenary sessions were held between the 14th Congress and the 15th Congress. When the CC was not in session, decision-making powers were transferred to inner bodies of the CC itself; the Politburo, Secretariat and Orgburo (none of these bodies were permanent either, but convened several times a months).
