Must there be an interview record in the criminal case file?

Personally, I think it is possible. According to the provisions of Article 36 of the Criminal Procedure Law, defense lawyers can consult, extract and copy the litigation documents and technical appraisal materials of this case from the date when the people's procuratorate examines and prosecutes the case, and can meet and correspond with the criminal suspect in custody. Other defenders, with the permission of the People's Procuratorate, may also consult, extract and copy the above-mentioned materials, and meet and correspond with criminal suspects in custody. Since the people's court accepted the case, the defense lawyer can consult, extract and copy the materials of the alleged criminal facts in this case, and can meet and correspond with the defendant in custody. With the permission of the people's court, other defenders may also consult, extract and copy the above materials, and meet and correspond with the defendant in custody. Article 34 of the Lawyers Law: The entrusted lawyer has the right to consult, extract and copy the litigation documents and files related to this case from the date of case review and prosecution. The entrusted lawyer has the right to consult, extract and copy all the materials related to the case from the date when the people's court accepts the case, that is to say, the lawyer has the right to consult, extract and copy the relevant case files, and there is no explicit prohibition in laws and regulations to show the materials to the parties for browsing. So personally, I think it's ok, but I think if the case involves state secrets, other privacy-related things can't be shown to the parties!
