Outline of Final Research Achievements

During the last four years, I researched about the burden of evidence of a party　who does not bear the burden of proof. I reported my research at　Japan Association Kansai branch of the Law of Civil Procedure as a result of this research (2022/02/06) and published my consideration in “Theory and Practices about civil justice of next generation”(2023, 05).
I compared similar provision (e.g. Article 248) in intellectual property litigation and civil litigation. Because the provisions which lighten the burden on the parties involved in intellectual property litigation success effectiveness ahead of similar provisions in civil litigation. I analyzed the reasons despite the fact that the provision was originally derived from a civil litigation. the perspectives of such analysis are unprecedented approach. I made a suggestion that we must have more deeper understanding about the relationship between two systems.

Academic Significance and Societal Importance of the Research Achievements

民事訴訟法における証明責任を負わない当事者の協力義務（事案解明義務）について、長らく議論があるものの、当該義務の存在についての学説の一致を見ない状況にあることから、本研究は、民事訴訟法の周辺諸法において、事案解明義務に基づくと解される各規定について、検討を行うことで、民事訴訟法における事案解明義務の存在を肯定するための示唆を得ようと試みた点に意義がある。
情報や証拠の偏在が構造的に生じる周辺の訴訟類型において、事案解明義務に基づくと解される規定をめぐる議論状況を帰納的に比較することは、従来、民訴法の内部でのみなされていた議論にこれまでにない外的視点を示したことに社会的意義がある。
