正当法律程序,作为反映现代民主法治理念的重要程序理论,因其内蕴的普适公正性而越来越受到世界各国的普遍认可,并作为考量司法程序是否文明、理性的重要理论标准。但对于刑事诉讼中何为“正当程序”并无普遍的共识,本文从正当法律程序的内涵、判断基准以及违反正当法律程序的法律效果等方面对正当法律程序原则进行探讨与分析。 Legitimate legal procedure, as an important procedural theory reflecting the concept of modern democratic rule of law, is increasingly recognized by all countries in the world due to its inherent universal fairness and serves as an important theoretical criterion for considering whether a judicial proceeding is civilized or rational. However, there is no universal consensus on what constitutes “due process” in criminal proceedings. This article explores and analyzes the principles of due process from the perspectives of proper legal procedure, judgment basis and the legal effect of violating proper legal procedure.
