Legal analysis: 1. All public prosecution cases are undertaken by the procuratorate. 2. The public security organ has the power of investigation, and the evidence collected by the public security organ can be used as the evidence of the procuratorate, but the public security organ is not qualified to give evidence to the court. 3. Administrative organs other than public security organs (such as supervision, customs, industry and commerce, taxation, production safety supervision and drug supervision organs) have the obligation to investigate and collect evidence within the scope of their duties, but they are not qualified to give evidence to the court. 4. The evidence collected by public security organs and other government organs shall be examined by the procuratorate to decide whether to provide it to the court as evidence. The procuratorate can also collect evidence on its own and provide it to the court. The court has the right to investigate and collect evidence. When obtaining evidence, the court may notify the defense lawyer or prosecutor to be present. 6. The defendant has no obligation to prove his guilt. No one can be forced to prove his guilt. The defendant pleaded guilty voluntarily. If there is no other evidence, the court will not accept it. 7. Defenders and defendants have the right to prove the lightest or innocent evidence of the defendant.
Legal basis: Article 51 of the Criminal Procedure Law of People's Republic of China (PRC) stipulates that the burden of proof of the defendant's guilt in a public prosecution case shall be borne by the people's procuratorate, and the burden of proof of the defendant's guilt in a private prosecution case shall be borne by the private prosecutor.
