Facilitating smooth coordination between supervisory investigations and criminal litigation procedures is an essential requirement for enhancing the efficiency and impartiality of the anti-corruption campaign. Firstly, the article discusses the importance of integrating supervisory investigations with criminal litigation procedures from three aspects: the practical needs of Chinese anti-corruption efforts, the requirement to respect and safeguard human rights principles, and the consequences brought about by the trial-centric litigation approach. Subsequently, the article examines the current legal and practical operational situations regarding the integration of supervisory investigations with criminal litigation procedures, explicitly highlighting their deficiencies and issues. Lastly,an analysis and discussion were conducted on the procedures for filing cases, detention measures, and criminal enforcement measures for supervision investigations and criminal litigation, as well as the application of evidence in supervision and criminal cases. Suggestions for improvement were put forward concerning the leniency system for confession and leniency, aiming to further safeguard the legitimate rights and interests of parties in duty-related criminal cases and contribute to the reform and improvement of relevant litigation systems.
