Legal analysis: The courts and procuratorates are independent. The procuratorate is the legal supervision organ of the country, and it is also the examination and prosecution organ of public prosecution cases. Its main duties are to examine and approve arrests, investigate self-investigation cases, examine and prosecute, and prosecute and appear in court as the prosecution in all public prosecution cases. The court is the judicial organ of the state, and its main duty is to exercise judicial power according to law, including trying civil cases, criminal cases and administrative cases. The relationship between the court and the superior court is trial supervision, not the leadership of the procuratorate. In criminal prosecution cases, the procuratorate, the court and the public security are in a relationship of division of labor, cooperation and mutual supervision.
