Can materials from the criminal investigation stage be copied? Since the People's Court accepted the case, the defense lawyer can review, excerpt, and copy the materials charging the criminal facts in the case, and can meet and communicate with the defendant in custody. With the permission of the People's Court, other defenders may also review, excerpt, and copy the above-mentioned materials, and meet and communicate with the detained defendant. Article 36 of the Criminal Procedure Law stipulates that from the date of review of the prosecution case by the People's Procuratorate, the defense lawyer or other defender entrusted by the criminal suspect may meet and communicate with the criminal suspect in custody. In other words, except for these two categories of people who can meet with the criminal suspect before the judgment of the case is delivered and executed, other people are not allowed to meet. If relatives or others want to see the criminal suspect, they can only wait until the case is finalized and handed over for execution.
