The problems and judicial review over the administrative obligation of investigation and to provide information

行政机关为了开展行政活动，有义务向公众提供信息，或对事实和法律问题进行调查。根据对日本案例的分析，这些义务不仅以法律规定为基础，而且以不成文法为基础。这些义务的违反被推定为政府责任，特别是在2004年新行政诉讼法修订后，可能受到其他行政诉讼的控制。

The Administration, in order to perform the administrative activities, is obliged to provide the information to the public or, to investigate the facts and legal issues. According to the analysis of Japanese cases, these obligations are imposed not only on the base of the provisions of the law, but also on the base of Jori(unwritten law). It is supposed that the breach of these obligations results in a government liability, and, especially after the amendment by the New Administrative Litigation Law of 2004, may be controlled by other administrative litigation.
