Democratic centralism is an organizational principle conceived by Lenin. According to Soviet pronouncements, democratic centralism was distinguished from "bureaucratic centralism", which referred to high-handed formulae without knowledge or discussion. In democratic centralism, decisions are taken after discussions, but once the general party line has been formed, discussion on the subject must cease. No member or organizational institution may dissent on a policy after it has been agreed upon by the party's governing body; to do so would lead to expulsion from the party (formalized at the 10th Congress). Because of this stance, Lenin initiated a ban on factions, which was approved at the 10th Congress.
