Can the criminal case file be handed over to the client after the case is closed?

Legal analysis: no, the parties can't leave the file, and the defense lawyer can only copy the file and can't take it out of court.

Legal basis: Article 38 of the Criminal Procedure Law of People's Republic of China (PRC). From the date when 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.
