The Principle of Use of Force in Contemporary International Law : Its Situation

本研究主要从当代国际法规范制定过程、宪法与国际公法的关系、多边环境协定中的不遵守程序、国际法院的政治问题理论以及战争法和国际安全理论等角度对使用武力原则进行研究。《联合国宪章》明确规定战争是非法的，这是第一次世界大战的产物，所有会员国都不得以武力相威胁和使用武力。然而，关于使用武力原则的立场及其对保障系统的有效性，我们还有讨论的余地。研究者们都认同这一基本认识，在研究项目的整个过程中，他们一直在处理各自感兴趣的问题。IDA教授考虑了国际法的规范及其制定过程。安藤教授从国际合作背景下的国际安全角度对日本宪法进行了评价，并参照日本的态度对战争法进行了审议。NISHII教授仔细研究了多边环境协定中不遵守情事程序的作用及其今后发展的可能性。此外，杉原教授还在国际法院中专注于政治问题理论。每个调查员都把自己的工作编成了文章。

This research focuses on the principle of use of force from perspectives of the norm making process in contemporary international law, the implication between the constitutional law and public international law, the non-compliance procedure in multilateral environmental agreements and the political issue theory of the International Court of Justice as well as the law of war and the international security theory,The outlawry of war being descended from the First World War has been explicitly ruled in the United Nations Charter in that all members shall refrain from the threat and use of force. Nevertheless, we have a room for discussion concerning the position of the principle of use of force and its effectiveness of securing systems.Sharing this basic recognition, the investigators have dealt with each own interested issue all the way of the research project so far Prof. IDA has considered the norms of international law and its making process. Prof. ANDO has evaluated the Japanese constitutional law on a perspective of international security in the context of international cooperation and has considered the law of war with reference to the Japanese attitudes. Prof. NISHII has scrutinized the role of the non-compliance procedures in multilateral environmental agreements and its possibility of future development. Furthermore, Prof. SUGIHARA has focused on the political issue theory in the International Court of Justice. Each investigator has made up his work into articles.
