What is the right of defense lawyers to read papers?

Article 36 of the current Criminal Procedure Law stipulates that defense lawyers may consult, extract and copy the litigation documents and technical appraisal materials of this case from the date when the people's procuratorate examines and prosecutes the case. The draft amendment to the Criminal Procedure Law stipulates: "When the investigation organ transfers it for examination and prosecution, it shall hand over all the case materials to the people's procuratorate. After the case is transferred for prosecution, the defense lawyer can go to the people's procuratorate to consult, extract and copy all the case materials of this case, including the evidence favorable and unfavorable to the criminal suspect. The people's procuratorate shall, within three days after the case is transferred for examination and prosecution, notify the defense lawyer in writing to read the papers. " According to this regulation, lawyers can only see a small amount of materials such as search warrants, detention warrants, arrest warrants, prosecution opinions and judicial expertise. In the prosecution stage, the procuratorate has the right to prevent lawyers from reading the confession and other evidence materials of criminal suspects.
