This article investigates a prominent but little discussed CCP central organ, the Central Discipline Inspection Commission (CDIC), and its local discipline inspection commissions (DICs) in the post-Mao era. It analyses how the CCP exerts its control over the disciplinary organizations and argues that the disciplinary agencies' lack of autonomy hinders their efforts to crack down on corruption. This article investigates the important role played by the CDIC in CCP politics by examining its organizational structure, modes of operation and criteria for imposing disciplinary sanctions, and evaluates the measures and approaches employed by the Party's disciplinary organizations to combat corruption. The study concludes that structural, institutional and cultural factors hinder the effectiveness of the CCP's disciplinary agencies in their efforts to control Party members, officials and corruption.
