Criminal cases have to go through the investigation stage, the prosecution stage and the trial stage. You can't disclose the case at the investigation stage. The court volume is the case file material formed after the case entered the people's court, which is divided into the main court volume and the auxiliary court volume. The main volume is a material that can be made public, and the auxiliary volume is an archival material that is not made public according to law.
According to the provisions of the Criminal Procedure Law of People's Republic of China (PRC), Article 40 Since the people's procuratorate examines and prosecutes the case, the defense lawyer may consult, extract and copy the case file. Other defenders may also consult, extract and copy the above materials with the permission of the people's court or the people's procuratorate.
