China's "Criminal Procedure Law" stipulates that after a criminal case enters the investigation procedure, the defense lawyer can consult the case file; After entering the public prosecution stage, the defense lawyer can consult all the files; After entering the trial procedure, the defense lawyer can consult all the files. However, there is no provision for the right of the defendant and the criminal suspect to read the papers. Such a provision is also considered from the nature of criminal cases. According to the regulations, the complainant in a criminal appeal case cannot directly consult the criminal case file of this case, and only the defense lawyer entrusted by him can consult the relevant case file with the approval of the court. Article 49 of the Criminal Procedure Law: Defenders and agents ad litem have the right to appeal or accuse public security organs, people's procuratorates, people's courts and their staff members of obstructing them from exercising their litigation rights according to law. The people's procuratorate shall promptly review the complaint or accusation, and if the situation is true, notify the relevant authorities to correct it.
