When Joseph Stalin rose to power, he merged Rabkrin with the CPSU Party Control Committee, only to un-merge them in the 1930s.

Officials found guilty of illegalities could be publicly reprimanded, fined for damages, or referred to the procurator for prosecution.

General meetings of work collectives at every enterprise and office elected the committees for tenures of two and one-half years.
