随着体制改革工作的进一步深入,公安机关内部机构的合并,使得机构更精简,从而提高办案效率,这是公安工作改革的一大举措。侦察和预审两部门合并后,预审部门已不存在了。但预审工作确是整个刑事诉讼中必不可少的重要环节,按照法律规定,其与侦察工作既相关连且相对独立,所以侦审合一以后的业务案卷名称需要有一个科学的命名。 With the deepening of the reform of the system, the merger of the internal organs of the public security organs will make the organization more streamlined and thus improve the efficiency of handling cases. This is a major move in the reform of public security work. After the merger of reconnaissance and pre-trial departments, the pre-trial department no longer exists. However, the pre-trial work is indeed an indispensable part of the entire criminal procedure. According to the law, it is both related and independent to the reconnaissance work. Therefore, it is necessary to have a scientific naming after the investigation of the name of the business case paper after the unity.
