  • サプライチェーン型売買モデルを基礎にした新たな国際統一契約法策定に向けた政策提言

    Grant number：23K01118

    Grant amount：\3120000 （ Direct Cost: \2400000 、 Indirect Cost：\720000 ）

    2023年度は、サプライチェーンの中で行われる物品売買という取引において、契約法の適用対象となりうるような法的問題が起きうるのか、問題が起きうる法的文脈の同定をすべく、取引構造の分析を行なった。具体的には、サプライチェーンの中で行われる物品売買における各種の問題状況は、サプライチェーンマネジメントとして経済・経営・社会学の視点から議論されていることから、そこでの議論を分析することを通じて、いかなる問題状況がありうるのかを抽出し、それと、契約法が対象とするべき法的文脈があるのか、また、ある場合にどの程度の頻度で当該法的文脈が生じる可能性があるのかについて考察を進めた。サプライチェーンマネジメントにおける議論については、理論的側面からの議論と、実務的側面からの議論があるところ、その双方を足がかりにしつつも、2023年度は、理論的側面からの考察を進めた。
    一方では、契約法が対象とする法的文脈は、サプライチェーンにおける物品売買契約においては問題になりにくいのではとの仮定が成り立つものの、それは、そもそも契約法が想定するような法律問題が起きないという意味ではなく、起きる可能性はあるものの対処法がサプライチェーンの仕組みあるいはそこで取り交わされる売買契約の中に折り込み済みであるからではないかと考えられた。その意味では、サプライチェーンにおける物品取引に関して生じる法的諸問題については、事前の予防策の重要性が大きく、その分、事後的な紛争予防策である契約法の実践的な役割が小さくなっていると考えられる。この点から、サプライチェーン型売買における事前の予防策に焦点を当てつつ、その中で契約法としてどのようなルール設計が必要となるのかについて考察を進めるべきではないかとの方向性を得た。

  • Study on Trustee's Duties of Care and Loyalty in Asset Management Schemes for the Elderly

    Japan Society for the Promotion of Science  Grants-in-Aid for Scientific Research

    4 2016 - 3 2018

    Grant number：16K17039

    Grant amount：\1690000 （ Direct Cost: \1300000 、 Indirect Cost：\390000 ）

    In response to the rapidly aging society, there are increasing needs among the elderly for managing their assets in trust schemes in Japan. This is posing new challenges to Japanese trust law, because trusts have been primarily used by trust banks to create investment schemes in Japan, while private trusts to manage one's assets and/or leaving assets to his family members have hardly ever been utilized. Therefore, it is necessary to focus on rules on such private trusts by tailoring existing rules created based on commercial trusts. This research aims to meet the necessity by employing comparative legal study primarily on English trust law.
