The diversion function of criminal special procedure has not been fully displayed in Macau. The current undergoing reform suggestion tries to transplant the regulations in the Criminal Procedure Code of Portugal to solve the problem of the heavy caseload in Macau. However, the abbreviated procedure as well as the system of special criminal procedure set up by the Portugal CPC in 1998 cannot represent the trend and common practices of civil law countries any more. Thus, it is necessary to consider possible ways for Macau to revise the criminal procedure, especially to consider the special procedure when a confession is already made by the defendant with or without negotiation.
