刑事诉讼法规定，公安机关认为人民检察院所作出的不批准逮捕决定和不起诉决定有错误的时候，可以要求复议。但对复议程序来作进一步具体规定。实践中，有的公安机关对人民检察院作出的不铺、不诉决定，在要求复议的同时，又向人民检察院移送补充侦查的新的证据材料，并以此作? The Criminal Procedure Law stipulates that the public security organ may request a reconsideration when it considers that the people’s procuratorate has made an erroneous decision not to approve the arrest decision and the non-prosecution decision. However, the reconsideration procedure should be further specified. In practice, some public security organs do not pave the way for people’s procuratorates to decide whether to go to the People’s Procuratorate or not, and when they request reconsideration, they also send new evidence materials for supplementary investigation to the People’s Procuratorate and use it as their basis.
