侦查、起诉、审判是刑事诉讼的三大环节,起诉前承侦查,后启审判,在刑事诉讼中起着不可忽视的枢纽作用,所以要构筑公诉案件质量保障机制。在起诉环节构筑案件质量保障机制,应建立三个机制:受案前的引导侦查取证机制、受案后审查起诉机制和结案后监督引导考评机制。 Prosecution, prosecution and trial are the three major aspects of criminal prosecution. Before the prosecution, the investigation and prosecution will play a pivotal role in criminal proceedings. Therefore, it is necessary to establish a quality assurance mechanism for public prosecution cases. In the prosecution part to build the case quality assurance mechanism should establish three mechanisms: before the case of the guidance of the investigation and evidence collection system, after the prosecution of the prosecution mechanism and the supervision and guidance after the close evaluation mechanism.
