Can a criminal case be withdrawn after it is filed?

The police station only files a case for investigation. During the investigation, if the facts are unclear or the evidence is insufficient, the police station will stop the investigation. The investigation by public security organs is a state act, not a private act, which can not be solved by private people who want to mediate, and private people are not allowed to interfere. For criminal cases of private prosecution, Article 172 of China's Criminal Procedure Law stipulates that "mediation can be conducted, and the private prosecutor can reconcile with the defendant or withdraw the private prosecution before sentencing." However, if it is a case where the victim has evidence to prove that the defendant should be investigated for criminal responsibility according to law, but the public security organ or the people's procuratorate will not investigate the defendant's criminal responsibility, mediation is not applicable. For public prosecution cases, the decision to withdraw the case lies with the procuratorate, and the victim can accept mediation on the civil part attached to the criminal case. According to the law, if a case is prosecuted, criminal responsibility shall not be investigated. If it has been investigated, the case shall be dismissed, or no prosecution shall be instituted, or the trial shall be terminated, or the case shall be declared innocent: (1) The circumstances are obviously minor and the harm is not great, and it is not considered a crime; (two) the crime has passed the limitation period; (3) Being exempted from punishment by an amnesty order; (4) Failing to tell or withdrawing a crime that should be dealt with only after being told according to the Criminal Law; (5) The criminal suspect or defendant dies; (six) other legal basis for exemption from criminal responsibility according to law.
