At the first trial, the lawyer said that the evidence was insufficient. Does the court still need to investigate?

Legal analysis: supplementary investigation will be returned. In a criminal case, if the court finds the defendant guilty due to insufficient evidence, it shall make an acquittal due to insufficient evidence and the alleged charges cannot be established.

Legal basis: Article 200 of the Criminal Procedure Law of People's Republic of China (PRC). After the defendant's final statement, the presiding judge announced an adjournment and the collegial panel conducted a review. According to the ascertained facts, evidence and relevant laws and regulations, the following judgments are made respectively:

(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 shall 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.
