Abstract: | The “trial-centered” litigation system reform, as a major task of China’s judicial reform, has drawn much attention due to its protection of the legitimate rights and interests of citizens as well as the maintenance of judicial fairness and authority. In the new-era background, the reform of the “trial-centered” litigation system will inevitably set new requirements on the litigation function, litigation structure and the judicial system as well. The perfection and reconstruction of the criminal defense system, as an indispensable part of the reform, is doomed to be an essential requirement concerning the realization of “trial-centered”. In a word, to perfect the criminal defense system is to reconstruct the lawyer defense system on the basis of a deep understanding of the connotation as “trial-centered”. To be specific, it refers to the following four aspects in the new judicial field as the full coverage of judicial field, the integration of configuration mode, the protection of subjective rights as well as the substantiation of functional effectiveness. |
