Subjectivity of law: when does the period of legal prosecution begin? According to the criminal law of our country, the time limit for prosecution shall be counted from the date of the crime, and if the crime is continuous or continuous, it shall be counted from the date of the end of the crime. The time limit for prosecution refers to the effective period for investigating crimes or torts in accordance with the provisions of the Criminal Law. If a crime is committed within the time limit for prosecution, the time limit for prosecution of the former crime shall be counted from the date when the latter crime is committed. If the criminal act has exceeded the limitation period prescribed by law, legal responsibility shall not be investigated; If the legal responsibility has been investigated, the case should be dismissed. The limitation period of prosecution in criminal cases is defined according to the severity of legal punishment for various crimes:1; If the statutory maximum penalty is less than five years of fixed-term imprisonment, the limitation period is five years; 2.
