On the morning of June 13, 2019, Professor Deng Zibin, a research fellow at CASS Institute of Law and a doctoral supervisor at CASS Graduate School, gave a lecture entitled “the practical significance of the division of litigation mode theories”. The lecture was sponsored by the Graduate School of Northwest University of Political Science of Law, presided over by Professor Fu Yuming, Director of the Institute of Legal Science Information of Northwest University of Political Science of Law, and attended by teachers and students of the Criminal Law School of the University.

In the lecture, Professor Deng discussed the differences between the form and the substance of litigation, examined the relationship between procedure and substance of criminal litigation through the analysis of a large number of cases, and pointed out that the theoretical significance of debate between “the Doctrine of Three Tiers” and “the Doctrine of Four Elements” is to carry out comparative analysis between inquisitorial and adversarial litigation modes and between the crime control mode and the due process mode, and the focus of the due process mode is the lawfulness of procedure, rather than the legitimacy of the result. After the lecture, Professor answered questions raised by the audience and stressed that the basic difference between different litigation mode lies in the question of how to treat or use illegally obtained evidence, or the question of whether or not to recognize the principle of exclusion of illegally obtained evidence.
