How many times can I appeal to the Supreme People's Court for criminal cases?

If a party or legal representative appeals for a revision of the sentence, the request made by his close relatives to the public security and judicial organs because they refuse to accept the effective form, judgment, ruling and final decision of the public security and judicial organs shall be re-examined. In principle, there is no time limit for judicial organs to apply for criminal proceedings, but there are exceptions. The Supreme Law once said that the complainant in a criminal case should accept the complaint within two years after the execution of the penalty and file a complaint for more than two years. If the defendant in the original trial may be innocent, he should lodge a complaint within two years, but if the people's court refuses to accept it, it should also accept the jurisdiction of the appeal level stipulated by us in practice. The people's court or the people's procuratorate at the same level, which is responsible according to the classification and makes an effective judgment on the reasons for its location, accepts the appeal, but the people's court at a higher level and the people's procuratorate generally refuse to accept it and refuse judicial treatment. Due to appropriate procedural restrictions, if there are no new facts and reasons, the people's court at a higher level and the people's procuratorate at the provincial level may make a decision to terminate the case, and will no longer accept the case appeal after the termination. Then the lawyer's agency appeal system means that the lawyer can be entrusted to appeal.
