Outline of Final Research Achievements

In this research project, I clarified the content of the guarantee of the "openness to parties", which is a principle that guarantees the transparency of the civil proceedings and the possibility of influencing the proceedings to the litigant parties. From this point of view, I critically examined the use of "written statements", which have been generally used in court practice without any grounding express provisions. Through the research method of examining from both theoretical and practical perspectives, I proposed operational rules for the use of written statements, based on the current state of legal practice, that sufficiently guarantees the content of the principle of openness to the parties. The results of the research were presented at two research meetings and published in a paper.

民事訴訟法

Academic Significance and Societal Importance of the Research Achievements

当事者等の供述を記載した書面である「陳述書」は、民事裁判実務において、幅広く活用されているものの、法律に規定を持たないことから、その適法性や利用方法をめぐって激しい議論がある。現行法の改正作業の際にも言及されたものの、結果的には、何ら規定が設けられず、立法的な解決にも至っていない。
このような状況に直面し、陳述書の適法性を担保できる運用規律の確立が喫緊の課題であった。
本研究は、この問題を初めて「当事者公開主義」の観点から分析し、かつ裁判実務と法理論の双方から考察を行うことで、裁判実務において実行可能であり、かつ法理論上の適法性を確保できる陳述書の運用規律を提言した点に、学術的・社会的意義がある。
