State public prosecution refers to the criminal proceedings brought by the state against criminals for the purpose of punishing crimes, maintaining national security, protecting national interests, or other specific purposes. The object of national public prosecution was criminal acts within the country, not just individual criminal acts. The proceedings of a national public prosecution were similar to other criminal proceedings, including the preparation of evidence, debate in court, and the making of a judgment. In criminal proceedings, the victim or his legal representative or agent ad litem may lodge a complaint, and the defendant may defend himself through his defense. The scope of application of national public prosecution was relatively wide, including major and complicated criminal cases and cases that had a significant impact on the criminal behavior of criminals. The cost of a national public prosecution was borne by the defendant, while the victim could share the cost by filing an collateral civil action. State public prosecution is an important form of criminal proceedings, which is of great significance to maintain social stability and protect the dignity of the country's laws.
