在法律解释方法论当中,语义解释方法在法律发现过程中占有非常重要的地位。从法律解释学的哲学基础来看,语义解释方法秉持的是一种“句法—语义分离论”的法律解释思维方式,但语义解释方法作为一种倾向于形式主义的法律解释方法,在法律解释的有效性问题上存在着一定的缺陷。从法律解释学研究的立场来看,哈特的法律规则有效性理论乃是一种典型的“句法—语义分离论”的法律解释理论,其对法律解释有效性问题的探究同样存在着一定的理论缺陷,值得我们反思。 In the legal interpretation methodology, the method of semantic interpretation occupies a very important position in the process of legal discovery. Seen from the philosophical basis of legal hermeneutics, the semantic interpretation method upholds a way of legal interpretation of “syntactic-semantic separation theory,” but as a method of legal interpretation that tends to formalism, There are some flaws in the validity of legal interpretation. From the standpoint of legal hermeneutics, Hart’s theory of validity of legal rules is a typical theory of legal interpretation of “syntactic-semantic separation theory”, and its exploration of the validity of legal interpretation also exists Certain theoretical flaws, it is worth our reflection.
