文章通过证据失权制度中诉讼正义价值的探讨,阐述制度合理性的同时直指现有相关制度的缺乏对证据失权带来的障碍和实体正义的落空。对证据失权的适用抱以审慎态度,同时在民诉法中完善相关制度才能发挥该制度的真正价值。 Through the discussion of the value of litigation justice in the system of evidence loss of discretion, the article expounds the rationality of the system and at the same time points out the obstacles to the loss of evidence and the failure of substantive justice caused by the lack of existing relevant systems. We should take a cautious attitude toward the application of evidence loss and at the same time improve the relevant system in Civil Procedure Law so as to exert the true value of the system.
