本文从司法判决切入主题,就如何追寻司法判决合法性展开了思考,并分别从法条主义和德沃金的原则论进行了分析论述,认为法条主义本身仍然面临无法逾越的缺陷,仅靠法教义学无法克服,德沃金的原则论虽然描绘了一种理想图景,但却仅限于理想形态之中。文章最后提出可以合法律性、程序合理性、裁判机构的权威性等方面共同构成支撑起司法判决合法性的基础。 This article from the judiciary judgments into the theme, on how to search for the legality of judicial judgments, and respectively, from the law of law and Dworkin’s theory of principle were analyzed and argued that the law of the article itself is still facing insurmountable defects, relying solely on Legal doctrine can not be overcome. Although Dworkin’s principle theory depicts an ideal picture, it is confined to the ideal form. Finally, the article puts forward that legal basis, procedural rationality and the authority of the judiciary can form the basis to support the legitimacy of judicial decisions.
