证据交换是庭审前的准备程序,在整个审判过程中有着重要的制度价值和功能:明确案件争议的主要问题;提高审判效率;降低诉讼成本;维护司法公平正义。但是也应该看到,证据交换制度设计的不完善也导致在十多年的实施过程中,逐渐暴露出许多不合理的缺陷。 Evidence exchange is a preparatory procedure before trial. It plays an important institutional value and function in the whole trial process. It clarifies the major issues in case disputes, improves the trial efficiency, reduces litigation costs, and maintains judicial fairness and justice. However, it should also be noted that the imperfect design of the system of exchange of evidence has also led to the gradual revealing of many unreasonable shortcomings in the course of more than a decade of implementation.
