Because the case is only in the investigation stage, lawyers can't go to the public security organs to consult the relevant case materials of criminal suspects, and defense lawyers can consult, extract and copy the case files from the date when the people's procuratorate examines and prosecutes the case. Other defenders may also consult, extract and copy the above materials with the permission of the people's court or the people's procuratorate. Therefore, the parties can verify according to the actual situation and relevant laws and regulations.

Article 38 From the date of examination and prosecution by the People's Procuratorate, defense lawyers may consult, extract and copy the case files. Other defenders may also consult, extract and copy the above materials with the permission of the people's court or the people's procuratorate.
