Abstract:At present, the reform of the supervisory system has been steadily advancing, and the Supervision Law has promoted the standardization and legalization of the handling of duty crimes by supervisory organs. However, there are still some problems in judicial practice, such as poor connection between supervision, prosecution and law at the level of procedural connection and transformation; there is no scientific connection and transformation between supervision and judicial departments in the disposal of duty crime cases; there are many disputes and ambiguities in the application of supervision measures. Therefore, we should further smooth the connection between supervision and criminal procedure, build a criminal justice path for the legalization andscientificalization of the power operation mechanism of the supervisory committee, promote its good interaction and restriction with the criminal procedure system, and standardize the power operation procedure mechanism of the supervisory organ. In terms of macro-system design, we should abide by the principle of procedural justice and separation, and rationalize the power allocation of supervision and judicial organs on the basis of the trial-centered pattern. At the operational level of micro-mechanism, we should implement the mechanism of diversion and judicial review of duty crimes, improve the application of lien procedure, and set up a reasonable supervision and restriction mode through the application of exclusion of illegal evidence and the construction of intelligent management platform of duty crimes cases in various stages of investigation, review, prosecution and trial.
