Legal analysis: the agent ad litem invited by the victim has the right to read the papers. Usually, we all know that the defense lawyer of the defendant in criminal cases can apply to the procuratorate for marking the papers during the examination and prosecution stage, that is, consulting, extracting and copying the files. As a victim, he can ask the agent ad litem to read the document during the examination and prosecution stage. But there is a premise that the victim's agent ad litem should be allowed to read the papers by the procuratorate. The defendant's defense lawyer doesn't need it. But in practice, the procuratorate generally agrees with the lawyer invited by the victim.
