The Validity of Appraisal Conclusions as Evidence CHEN Wei-dong LI Wei(China People's University School of Law;Beijng 00;China) 2007(03): 5-8+27.  Abstract ( )   The deve lopment of contemporary science and technology has caused the use of forensic appraisal in criminal cases. The co-existence of risk and importance of the forensic appraisal conclusion makes people seek for regulating the validity of appraisal as evidence. The common law system emphasizes reviewing the way evidence is obtained in determining the acceptability of expert evidence, while the civil law system stresses the control of appraisal conclusion by litigation procedure. On the basis of analyzing the different rules of the two legal systems regarding the validity of appraisal conclusions as evidence, this author proposes to improve the validity of appraisal conclusions as evidence in China by analyzing the qualification of experts, the relevance of the appraisal, the reliability of appraisal conclusions, the lawfulness of material used in the appraisal and the procedure of appraisal.

The Burden of Proof and Compulsive Expert Identification: Research on Identification of "Mental Illness" GUO Hua (Law School of the Central University of Finance and Economics;Beijing 000;China) 2007(03): 9-13.  Abstract ( )   The restricted criminal responsibility came into being with the development of practice in criminal responsibility of mental illness from "either responsible or not" to co-existence of medial form in Anglo-American Legal System. At the same time, the distribution of burden of proof of mental illness has grown from absolute burden to relative burden for the prosecutor, achieving the distributed way of the burden of providing evidence on the accused defendant and the burden of persuasion on the prosecutor. We should construct a compulsive identification system on the base of reasonable assignment of burden of proof about mental illness. So that we can improve the reasonable distribution of burden of proof and ensure the due process. Related Articles | Metrics

The Procedural Control over Conflicts of Appraisal Conclusions ZOU Ji-chao(The Procuratorate of Huangpu District;Shanghai;0000;China) 2007(03): 31-33.  Abstract ( )   The conflicts of appraisal conclusions refer to the differences, mutual opposites and exclusion, or interference of the conclusions. They influence the proper order of litigation in some respects. When we check on its mechanism, we come to realize that there exits a certain inevitability and it is a product with multi-factors. Therefore, we should take some procedural means to avoid the negative influence of the conflicts. When treating the conflicts of appraisal conclusions, we should apply some procedural rules and means to control. Related Articles | Metrics
