All evidence related to the case, including all confessions, must be made public at the court session. The only exception is evidence involving state secrets, business secrets and personal privacy, which is not public and can be kept confidential. The confession and excuse of a criminal suspect is a kind of evidence stipulated in the Criminal Procedure Law. When the procuratorate brings a lawsuit to the court, it will submit the confession made by the parties in the public security bureau as evidence to the court. During the trial, the prosecutor of the procuratorate will also present evidence materials such as confessions in court, and the defendant and his defense lawyer will conduct cross-examination. Finally, the court will make a determination in the judgment according to the cross-examination and make a corresponding judgment on the defendant.
Article 170 of the Criminal Procedure Law of People's Republic of China (PRC) People's Procuratorate shall, in accordance with the relevant provisions of this Law and the Supervision Law, hear cases transferred for prosecution by supervisory organs. If the people's procuratorate deems it necessary to make supplementary verification after trial, it shall return it to the supervisory organ for supplementary investigation, and may make supplementary investigation on its own if necessary. The people's procuratorate shall first detain the criminal suspect in the case that the supervisory organ has transferred for prosecution, and the lien measures shall be automatically lifted. The people's procuratorate shall, within ten days after detention, make a decision on whether to arrest, get a bail pending trial or monitor residence. Under special circumstances, the decision time can be extended by one to four days. The period during which the people's procuratorate decides to take compulsory measures shall not be counted in the period of examination and prosecution. Article 175 When examining a case, a people's procuratorate may request the public security organ to provide evidence materials necessary for the trial. If it is believed that there may be illegal methods to collect evidence, it may be required to explain the legality of collecting evidence. When examining a case, the people's procuratorate may return it to the public security organ for supplementary investigation or conduct its own investigation. A case under supplementary investigation shall be completed within one month. Supplementary investigation is limited to two times. After the supplementary investigation is transferred to the people's procuratorate, the people's procuratorate recalculates the time limit for examination and prosecution. If the people's procuratorate still believes that the evidence is insufficient and does not meet the conditions for prosecution in the case of the second supplementary investigation, it shall make a decision not to prosecute.
