保障被告人的合法权益,实现诉讼公正是共同犯罪分案诉讼的宗旨,然而共同犯罪的分案也存在许多弊端,如出现互相矛盾的判决影响司法权威等。在实践中,由于当前在我国共同犯罪分案诉讼制度上立法不完善,分案诉讼有时沦为迎合业绩考核的手段。要使分案诉讼更好的发挥自己的功能,必须要从完善法律规范,保障被告人的救济权,加强检察监督等方面出发。 To safeguard the legal rights and interests of defendants and to realize the fairness of litigation is the purpose of the joint criminal division proceedings. However, the division of joint crimes has many drawbacks, such as conflicting judgments affecting judicial authority. In practice, due to the current imperfect legislation in our country’s joint criminal proceedings suit, sometimes the divisional suit is reduced to a means to meet the performance appraisal. In order to make divisional lawsuits better play their own functions, we must start from the aspects of perfecting laws and regulations, guaranteeing defendant’s right to relief, and strengthening procuratorial supervision.
