The filing of a case by the police station is only for investigation. If the facts are unclear or the evidence is insufficient during the investigation, the police station will stop the investigation. The filing and investigation of cases by public security organs is an act of the state, not a private act. It cannot be settled by private individuals' mediation, and private individuals are not allowed to interfere. For private prosecution criminal cases, Article 172 of my country's Criminal Procedure Law stipulates that "mediation may be carried out, and the private prosecutor may reconcile with the defendant or withdraw the private prosecution before the judgment is pronounced." However, if the victim has evidence to prove his case against the defendant, Mediation is not applicable to cases in which a person's behavior that infringes upon his or her personal or property rights shall be investigated for criminal liability in accordance with the law, but the public security organ or the People's Procuratorate does not investigate the defendant's criminal liability." For public prosecution cases, the decision to withdraw the case rests with the prosecutorial office, and the victim can accept mediation for the civil part of the criminal case. According to the law, if one of the following circumstances occurs in a public prosecution case, criminal liability will not be pursued. If the case has been investigated, the case should be dismissed, or no prosecution should be terminated, or the trial should be terminated, or acquittal should be acquitted: (1) The circumstances are obviously minor and the harm is not great , is not considered a crime; (2) The crime has passed the statute of limitations for prosecution; (3) The crime is exempted from punishment by a pardon order; (4) The crime is handled only after complaint in accordance with the criminal law, but no complaint is made or the complaint is withdrawn; (5) Crime The suspect or defendant dies; (6) The legal basis for exemption from criminal liability under other legal provisions.
