The codification presupposes the absence of a unified codein a given field,making the no-tion of"codification of the Criminal Procedure Law"logically untenable.That being said,the issue of o-verly fragmented legislation,which codification aims to resolve,also exists in the field of criminal proce-dure.Judicial interpretation documents issued independently by public security and judicial organs have fragmented and hollowed out the Criminal Procedure Law,leading to a noticeable phenomenon of decodi-fication.This has caused serious issues such as diminution of legal authority,erosion of legal stability,distortion of legal values,and weakening of the legal system.To address the situation of"regulations substituting for law",restore the authority of law,maintain legal stability,reestablish legal unity,and enhance legal autonomy,a recodification of the existing normative system is necessary.Against the back-drop of the fourth amendment to the Criminal Procedure Law,it is essential to re-evaluate all existing regulations in the field of criminal procedure.Through appropriate models and techniques,one should re-fine and consolidate these regulations,and then compile them into a new,complete,and harmonious code.This task is a historical responsibility to be fulfilled in the era of codification.
