The case-deliberation mechanism of the procuratorial committee is a unique procedural scene in the operation of procuratorial power. However，the “democratic centralization” approach does not necessarily mean the realization of collective wisdom. There are always conflicts that are difficult to reconcile between the special laws of case-handling activities and the substantive functions of bills. From the mechanism-function perspective，it is not difficult to find that problems such as the imbalance of organizational structure function，insufficient decision-making basis，and low quality and efficiency of the proposals still exist objectively. In order to complete its decision-making，the procuratorial committee has either alienated the relationship with the prosecutor and over-relied on the individual handling the case；or alienated the decision-making process and extended the decision-making body. The fundamental reason for the weakening of functions lies in the formal operation of the billing mechanism. At present，in the context of the reform of the standardized operation of the procuratorial power，the role of the auxiliary system of the prosecution committee’s meeting proposal mechanism should be strengthened to limit the scope of proposals and clarify the way members perform their duties to ensure that the procuratorial committee has the possession of decision-making information，thereby enhancing the Procuratorial committee decision-making ability.
