To protect the citizens’ legitimate civil rights from being violated or deprived is both the fundamental purpose of civil litigation and the core of the regulation on the theoretical and institutional construction of the civil litigation. The citizensT autonomy in exercising their private rights embodied in such purpose and core has been extended and applied into the civil procedure and transformed into the concept supporting civil litigation, disposition doctrine. The parties are granted the freedom of disposing their civil substantive rights and, more extensively, the right to go through or to abandon civil proceedings. As a procedural mechanism manifesting the above mentioned dual features of the disposition doctrine, the civil withdrawal system has been established in the modem civil procedural law. The Civil Procedural Law is not an exception. However, the provisions on the civil withdrawal system are not as specific as those on the system of filing civil cases, resulting in the considerably serious imbalance of interests and the disorder in regulating the courts exercising its solely enjoyed power to examine civil withdrawal. To solve these problems, the defendant's right to consent is introduced into article 238 of the Interpretation on the Application of the Civil Procedure Law of the People’s Republic of China (hereinafter referred to as the Interpretation on Civil Procedural Law), which is developed into a two-prong procedural construction of the defendant’s consent and the court’s final decision, and, to a great extent, promotes significant changes in the civil withdrawal system. However, new judicial interpretation on such systematic planning of the defendant s right to consent has brought about the possibility of regulation deviation and weakness of functions in many aspects instead of purification of rights, which need reflection and correction.
