According to the relevant provisions of the Criminal Procedure Law, the entrusted defense lawyer has the right to apply to the procuratorate and the court for marking. For defenders, this right is a legal right endowed by the Constitution and the Criminal Procedure Law. It can be seen that the right of defense lawyers to read papers comes from the law rather than the authorization of the parties and their relatives.
In addition to the right of defense lawyers to read papers, the attorney entrusted by the victim can also read papers after applying and obtaining the consent of the procuratorate and the court.
