The role and the position of the consititution in the private law

我们的研究是从民法研究和宪法学研究的角度来分析宪法在私法理论中的作用和地位。我们认识到宪法的每一条在构建私法方面的作用仍然没有解决，尽管私法领域的任何行为都应该被宪法作为国家最高法律来评估为违宪和非法的(见日本宪法第98条)。我们从民法研究的角度出发，通过使用民法第90条中阐明的关键字公共政策，来澄清什么是理论问题，以及，从宪法学研究的角度看，宪法理论对德国民法的影响已经积累了很多关于宪法与私法关系的研究积淀，我们可以通过对宪法在集体协议、环境保护等社会法中发挥重要作用的德国理论的研究，从民法的角度得出一些启示。这就要求我们在借鉴德国法学理论的基础上，进一步发展社会法领域的民法和宪法建设。

Our study is to analyze "the role and the position of the constitution in the private law theory" from the viewpoint of the civil law study and the constitutional law study.We recognize that the role of each article of the constitution remains unsolved to construct the private law, though any act in the private law sphere ought to be assessed unconstitutional and illegal by the constitution as the supreme Law of the Land (See the Article 98 of the Japan Constitution).We approached this issue to clarify, from the viewpoint civil law study, what is the theoretical problem, by using a keyword of "public policy" articulated in the Article 90 of the civil law, and, from the viewpoint of constitutional law study, what influence of the constitutional law theory makes on the civil law in Germany there are many research accumulation about the relationship between the constitution and the private law.We could obtain some suggestions, from the viewpoint of the civil law, by the research of the German theory in which the constitution has played an important role in the social law such as collective agreement and environmental protection. So we are required, on the basis of the German law theory, to develop the construction of the civil law and the constitution in the sphere of social law in the future.
