Outline of Final Research Achievements

In the 1990s, new torts proliferated. The purpose of this study is to make tort law theory compatible with today's tort cases. For this purpose, we investigated a variety of actual tort cases including those involving nuclear power plant accidents, asbestos construction materials diseases, life and medical service errors, market transactions troubles and online defamation. In this investigation, we examined the social background of these cases, including characteristics we tentatively labeled " complexity of social relations and risks. " Our investigation made clear that today's tort case law has characteristic tendencies including extension of the interests protected and the multiplication of duties to protect, including some types of professional liability. It also made clear that risk realizes itself in a different ways according to the category of the risk. It concludes with a number of concrete proposals for legal interpretations, institutions and legislations.

Academic Significance and Societal Importance of the Research Achievements

広い領域にわたる多数の個別事件の分析を踏まえて提示した不法行為法の理論は、未完成ではあるが、今日の諸問題に対する対応の基礎になると考えるものである。また、環境・生活、生命・医療、取引・市場の各領域の特性を考慮した、過失、保護法益、因果関係、損害等に関する個別の法解釈論、制度論の具体的な提言は、現実の諸事件に対しても有用な視点を提供するものである。本研究の成果は、全体として、法律学におけるリスク論に対する大きな貢献である。
