の大流行による重大な契約環境の変化に際し，日本法の下で契約当事者に対しいかなる法的救済が与えられているのかにつき，検討を行うものである．この点に関し，日本では，既存の個別の契約内容を修正するという方法による公的救済は行われておらず，法による他律的救済としての事情変更法理も，要件判断の厳格さ故に，その適用場面は極めて限られたものにならざるを得ない．ICC の不可抗力・ハードシップ条項などの例が示すように，事情変更に対応するための契約条項が今般のパンデミックに関しても事案に応じて適用され得るが，日本の契約実務においては，事情変更に備えて詳細な取り決めを行うという事前的対応は必ずしも十分にはなされないことが多く，契約締結後の再交渉および契約改訂合意を通じた事後的対応が，事情変更に際し重要な役割を果たしている．パンデミックに際して行われるそのような契約改訂交渉を支援する法制度としては，独禁法上の優越的地位の濫用や下請法上の禁止行為による規制が一定の機能を担っている．","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_4_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"特集　新型コロナウイルス感染症（COVID-19）への対応と社会科学","subitem_description_language":"ja","subitem_description_type":"Other"},{"subitem_description":"第一部","subitem_description_language":"ja","subitem_description_type":"Other"},{"subitem_description":"Featured
