A comprehensive analysis on the law of international civil procedure. -Conflict of state jurisdictions and its coordination.

根据笔者的研究计划，笔者分析了国家管辖权冲突的总体现象。从这个意义上说，湖人航空公司案是最具象征意义的案件之一。笔者认为，“域外适用与阻碍性法规”是一个恰当的词语，可以形象地表达目前的情况，国家管辖权的地域限制已经变得非常相对。效果理论不仅在反垄断法中，而且在其他领域，如税法和证券法中也得到了广泛的应用。英国冻结法中的“回拨”条款是一个重要的制度安排。这一问题在国外也没有得到很好的解决，本文通过对外国判决的承认与不承认这一经典问题的比较，对这一问题进行了探讨。根据这种动态的分析方法，本文还分析了所谓的“美日经济战”，如国际上最著名的双重诉讼案之一的IBM诉日立案。通过对国际管辖权、令状送达、主权豁免、美国的“国家行为“原则、破产的国际效力、国有化等问题的研究，使国际商事交易中的冲突法体系更加清晰，并对国际商事交易中的“风险管理”的各个方面进行了法律分析。我的研究成果可以在我的《现代国际志报》第一卷（东京大学出版社1986年）的第二部分中清楚地看到。

According to my research plan, I analyzed the total phenomena which occur through conflict of state jurisdictions. Laker Airways Case is in this sense one of the most symbolic cases. "Extraterritorial application vs. blocking statutes" is the suitable word to express the current situation vividly, I think.Territorial limitation on the use of state jurisdiction has bocome very relative. The effect theory is now widespread, not only in anti-trust laws but also in other fields, such as tax laws and security laws. The so-called claw-back provision in the blocking statute of U.K. brings us the most complicated conflicts law problem,which has not yet rightly solved also in foreign countries.I attacked this problem, comparing with the classic one of recognition and non-recognition of foreign judgments. According to such dynamic approach, I also analyzed the so-called "economic wars between U.S.A. and Japan", for example,the case of IBM vs. Hitachi,one of the most famous international double litigations case. In this way I have discussed international jurisdiction, service of writs, sovereign immunity, American "act of state"doctrine , international effect of bankruptcy, nationalization, and so on. Through my research, the system of conflict of laws has become very clear, and various aspects of "risk management" in international business transactions have been analyzed legally. The out-put of my research can be seen clearly in the second part of my "Gendai Kokusaishiho (Modern Conflict of Lwas in Japan) Vol. 1" (Tokyo University Press 1986).
