Abstract: According to relevant rules of criminal procedure, the parties in criminal procedure may only apply to start re-appraisal to relevant authorities （public security organs, people's procuratorates and courts）, and they have discretionary power to accept or reject the application. Sometimes, the parties can’t accept the decision, and contradictions occur between the parties and authorities. Tactics are employed by the parties in order to persuade or even manipulate the law practitioners to start re-appraisal. These tactics reveals some information, such as types of the re-appraisal, characteristics of the disagreement, etc. However, the fact that the parties sometimes take irrational or even illegal tactics shows the necessity for further reform of the mechanism to restart appraisals so as to reduce the irrational tactics of the parties.

摘要： 基于中国刑事法律的规定，当事人向侦控机关与法院申请重新鉴定，而至于是否被许可，则由三机关自由裁量。因申请主体与决定主体的二元分离，二者之间难免产生对立与冲突，故当事人为自身之利益而在实践中展现出系列行动策略，其目的是为了说服、甚至支配办案部门启动重新鉴定；该行动策略反映出当事人不满官方鉴定意见的案件结构特征。然而，当事人行动策略的恣意、非法、甚至暴力，说明中国目前的重新鉴定启动机制需要适当变革，以减少乃至限制当事人不合理的救济方式。
