How long does it take to close a criminal case with insufficient evidence?

Legal analysis: According to the different legal stages, there are three ways to close criminal cases with insufficient evidence and disposal procedures: First, after the public security organ files a case, it finds that the evidence is insufficient to prove that the criminal suspect has committed a criminal act after preliminary investigation and evidence collection, the public security organ refuses to file a case or cancels the case, releases the detained criminal suspect and ends the legal procedure. Second, the procuratorate refused to approve the arrest of the criminal suspect in cases where there was a serious shortage of evidence in custody, and the criminal suspect was released on bail pending trial. If the public security organ cannot obtain valid evidence in the subsequent investigation and evidence collection, it will not transfer the criminal suspect to the procuratorate for review and prosecution. After the expiration of one-year bail, the suspect will not be tried, let alone sentenced. Third, the court will make a verdict of innocence for cases with insufficient evidence transferred to the court for prosecution.

Legal basis: Article 55 of the Criminal Procedure Law of People's Republic of China (PRC) emphasizes evidence, investigation and research, and does not believe confession. If only the defendant confesses and there is no other evidence, the defendant cannot be found guilty and punished; If there is no confession from the defendant and the evidence is true and sufficient, the defendant may be found guilty and punished. If the evidence is true and sufficient, the following conditions shall be met: (1) The facts of conviction and sentencing are proved by evidence; (2) The evidence on which the final decision is based has been verified by legal procedures; (3) According to the evidence of the whole case, the ascertained facts have been beyond reasonable doubt. Article 200 of the Criminal Procedure Law of People's Republic of China (PRC) * * * After the defendant made his final statement, the presiding judge announced an adjournment, and the collegial panel made the following judgment after deliberation according to the facts, evidence and relevant laws and regulations: (1) If the facts of the case are clear, the evidence is true and sufficient, and the defendant is found guilty according to law, a guilty verdict will be made; (2) If the defendant is found innocent according to law, a verdict of innocence shall be made; (3) If the defendant cannot be found guilty due to insufficient evidence, a verdict of acquittal shall be made because the accused crime cannot be established due to insufficient evidence.
