大法院对大东水灾诉讼的判决否定了国家对水灾所造成的损失的赔偿责任。在传统的损害赔偿法律原则中，以预知可能性为前提，以逃避可能性为结果，不存在与社会再分配相对应的损害赔偿。正因如此，人们通过对损害的预防，在损害的社会表象分布中追求一种能够检验总量的“风险管理”思路。2009年德国《水法》引入了洪水风险管理制度。在德国法系中，国家对自然灾害（巨灾）的赔偿责任在原则上是否定的。此外，还指出了传统洪泛平原的使用和土地利用法规等法律制度的各种问题。

The damage responsibility of the country for the damage that occurred because of a flood was denied by Supreme Court Judgment for Daito Flood Suit. In a traditional compensation for damages principle of law to premise predictive possibility, result evasion possibility, there is not surely the corresponding to the social redistribution of the damage. By the reason of this, a way of thinking called "the risk management" that can examine total is pursued in the social appearance distribution of the damage by the prevention of the damage. And flood risk management system was introduced into German Water Law of 2009.In the German law system, the compensation responsibility of the country for the natural disaster (catastrophe) is denied in principle. Moreover, various problems of legal system, such as employment of the conventional flood plain and a land use regulation etc. are shown.
