Outline of Final Research Achievements

This research theoretically examined the de facto transformation of the UN Charter by applying the "constitutional transformation" theory in constitutional law and presented the theoretical issues in applying the said theory mutatis mutandis to the international law dimension.
In addition, it critically examined the methodological and theoretical problems of previous studies that attempted to introduce public law theory as a solution to the problem in functionalist approach to international organizations and indicated the necessity of an "ontological, teleological, and deontological" approach to the ideal way to introduce public law theory into international organization jurisprudence.
Furthermore, it shed light on the possibility that the interaction of multiple interpretative entities such as "interpretive communities" and their complex interpretations may have some influence on the interpretations of international organizational law and its development and transformation.

Academic Significance and Societal Importance of the Research Achievements

設立文書に基づく国際組織の実施の活動・実行の法的評価が国際法解釈の枠組みでは問題を生じつつも、グローバル社会のアクター・受益者の目線・要請からは更に柔軟・実効的であることが求められているという対立的な問題状況に対し、「変遷」という解釈論と立法論の架橋的理論枠組みを用いることで、国際組織の法理論研究がこの対立状況を止揚できる可能性に光を当てたこと、また、「変遷」理論の国際法次元への導入にあたり、グローバル公法・公法再検討論の研究成果に照らしてその要件である「法的確信」をグローバル社会の現状・構造の反映としての「承認」に修正し得る可能性を示したこと、以上が本研究成果の学術的意義である。
