Hello, regarding your question, first of all, you should distinguish what kind of criminal case your criminal case belongs to. In China, the system of second instance is implemented. If it is a criminal case of first instance, the legal appeal period is within 1 days from the second day after you receive the judgment. If you appeal within 1 days, that is, the case of first instance has not yet taken effect, then at this time, the defendant of first instance has the right to defend the unfair trial in the case of first instance. Effective, then at this time, the defendant in the first instance has the right to defend the unfair trial in the first instance. According to your situation, it should be a case during the second trial. regarding the access to the case file, it is suggested to hire a lawyer to defend the case at the second trial, because the lawyer law of our country stipulates that lawyers have the right to access the case file and evidence materials at the trial stage in criminal proceedings. This right is given to lawyers by law, so lawyers don't need to go through the examination and approval of the judicial organs when they get the case files. Moreover, lawyers can obtain all the evidence of a criminal case, not part of it. However, if a non-lawyer defender wants to obtain it, it must be approved and only part of the case file can be obtained. Therefore, based on this, if the fairness of the case is closely related to the facts of the case, it is suggested to hire a lawyer as a second-instance defender to obtain more materials and favorable evidence.
The place to consult can be the court. I think if you want to consult more records and investigate and collect evidence, you can also go to the procuratorate to have a try.
I hope there will be fairness and justice in the world! Wish you all the best. Come on.
