China's criminal law implements the principle of self-responsibility. When a criminal dies, escapes or loses his litigation ability, he loses the object of punishment, and the purpose of criminal law cannot be achieved. It is of no practical significance to pursue legal responsibility. Therefore, the court stops or ends the trial of a lawsuit when the criminal suspect or defendant is absent. The author thinks that although this procedure seems reasonable, it is often not conducive to litigation fairness and efficiency in judicial practice, and advocates drawing lessons from advanced legislation on trial by default in foreign criminal proceedings and establishing a criminal trial by default system that is suitable for China's social development in combination with China's specific national conditions and judicial practice.
