Outline of Final Research Achievements

This research showed that, in Australia, the scope of the Al-Kateb decision, which allowed for the indefinite detention of undocumented aliens, is becoming limited, and that is based on international human rights law. Others, EU court recognized that an immigration detention was a part of sovereignty and that there was a conflict with the restrictions imposed by international human rights law. Both studies showed that the restrictions of international human rights law on incarceration still varied from country and region.Furthermore, through interviews with those who operate immigration detention facilities and those who support detainees, as well as through reviews of books written by supporters, we clarified the differences in perceptions between the two groups and the actual conditions of detention and support.

Academic Significance and Societal Importance of the Research Achievements

本研究は、収容の必要最小限性・収容時の適切な処遇に焦点を当てて、国内法学者と国際法学者が共同し、学際的な観点から包括的に入管収容制度及び裁判例を批判的に検証する点に学術的意義がある。さらに、本研究は、理論的視点のみならず、実務との対話を通じて入管収容政策の検討の際に貴重な情報を提供する社会的意義も有している。
