Criminal litigation is an activity in which two parties in equal confrontation and disputes tell their disputes to neutral judges and ask the judges to solve their disputes. In criminal proceedings, the people's courts, people's procuratorates and public security organs should be responsible for the division of labor, cooperate with each other and restrict each other to ensure accurate and effective law enforcement. _ The People's Procuratorate shall supervise criminal proceedings according to law. When trying a case, the people's court shall openly carry out the system of "two trials as the final instance". Unless otherwise stipulated, the defendant has the right to be defended, and the people's court has the obligation to ensure that the defendant is defended. In addition, in order to further supervise criminal proceedings, the people's courts need to implement the jury system when trying cases. In some cases, judges, prosecutors and investigators should withdraw. The people's procuratorate shall supervise the legality of the decision and implementation of residential surveillance in designated residences.
2. Procedure of trial supervision
The parties, their legal representatives and close relatives may appeal to the people's court or the people's procuratorate against the legally effective judgment or ruling, but they may stop the execution of the judgment or ruling. If the parties, their legal representatives or close relatives disagree with the trial results, they may appeal. According to the relevant provisions of the Criminal Procedure Law, the conditions and reasons for the appeal are in line with the relevant provisions, and the people's court should retry the case, including the fact that the judges have committed corruption, bribery, favoritism and perverting the law in trying the case, which is also a manifestation of the supervision rules.
