Except for the materials involving state secrets and the internal materials of the court (such as the transcripts of the collegiate bench), all other file materials can be consulted. Generally speaking, we mainly grasp the following contents:
(1) indictment review. Focus on what crime is charged, the motive, purpose, time, place, means, circumstances and consequences of the crime, the position and role of the defendant in the crime, the severity of the crime, whether there is a lighter, mitigated or exempted punishment, and whether there is criminal responsibility. Review whether the legal provisions cited in the indictment are appropriate, etc.
(2) Review the evidence list and witness list. Lawyers can roughly understand the evidence system and types of the case by consulting the evidence catalogue and witness list, and check the relationship between the "main evidence" materials collected and the evidence materials that have not been collected to prove the facts of the case. Through the list of witnesses listed by the procuratorate, we can understand the role of other witnesses in proving the facts of this case, and through meeting with the defendant, we can understand how to carry out the investigation and collection of these evidences and witnesses' evidence beneficial to the defendant.
(3) Review of photocopies and photos of main evidence. Through the review of the main evidence, we can know whether the evidence of the defendant's conviction in this case is sufficient and true, which evidence has doubts and contradictions, so as to classify and exclude it, which evidence needs to be investigated and verified immediately, which evidence needs to be met with the defendant and which evidence needs to be verified during the court investigation.
