Article 10 of the Party Constitution sets the rule for decisions in Party committees. “All important questions are to be discussed and decided collectively by the Party committee, according to the principle of collective leadership, democratic centralism, individual deliberation and decision by meeting.”
In the original, the four steps are 集体领导、民主集中、个别酝酿、会议决定. The third, 个别酝酿, is deliberation with members one by one, before the meeting. The meeting comes last.
