Can a lawyer copy the criminal file?

There are two situations when you arrive at the procuratorate. One is that the case is in the stage of arrest, and the other is that the case is in the stage of litigation. The authority of lawyers in the two stages is different. In the arrest stage, the public security may still be in the investigation stage. In the investigation stage, lawyers can only provide legal help to the parties, but can't consult the files; In the stage of public prosecution, the provisions of China's criminal procedure law and lawyer law are inconsistent, and relevant materials can be consulted in judicial practice. This part of the material can be copied or shown to family members.
