Outline of Final Research Achievements

This study examined the question of whether or not the "role that the judiciary should play in Japanese society in the 21st century" as proposed in the reform of the judicial system has been fulfilled, and how it should be addressed in the future. Specifically, the following three points were examined:
First, what role should the judiciary play in cases where there is a competition between administrative action and judicial power (in particular, injunctions against illegal acts)? Second, how should the role of the family court be viewed in child support payment and visitation situations? Third, what are options for improving the civil enforcement system?

Academic Significance and Societal Importance of the Research Achievements

ここでは、行政作用と権限が競合する場合（とりわけ違法行為の差止め）に、司法がどのような役割を果たすべきかという課題について、民事差止訴訟の活用一辺倒ではなく、同趣旨の規制権限を有する行政庁の権限行使を求める義務付け訴訟を活用し、規制対象の事業者を同訴訟に参加させる（あたかも民事差止訴訟のように機能させる）という方法も選択肢に入れるべきという提言を挙げておきたい。この議論は、従来の行政法学における議論の延長線上に位置付けられ、また、民事差止訴訟が有する証拠収集や強制執行における弱点も補い得る構想として、意義があると考えられる。そのほか検討した問題については、研究成果報告を参照されたい。
