판결확정 후 피해자의 사망 또는 가동능력의 향상에 일시금지급확정판결에 미치는 영향

In this article, the writer gropes for the possibility of reclaiming the proportionate amount as unjust enrichment due to the death or advancement of impaired earning capacity of injured party after the final and conclusive judgment had been adjudged and executed. Several points the writer asserts in the groping process are as following. Firstly, the writer upholds the substantive law theory about the nature of res judicata. Secondly, if a final and conclusive judgment is adjudged on a money–claiming lawsuit, the grounds of demurrer against claims relate only to executive title regardless of the substantive legal relationships before raising that lawsuit or the substantively demurring grounds, and the remedies for unrighteous judgment must be discussed separately with the nature of demurrer against claims. Thirdly, the writer admits the existence of possible circumstances to raise lawsuits for recovery of damages or lawsuits for reclaiming unjust enrichment without revocation of the final and conclusive judgment through procedure for a retrial. But the writer does not opine the extent of those possible circumstances owing to the characteristics of this article. Majority opinions of scholars and the precedents permitting lawsuits for recovery of damages or reclaiming unjust enrichment assume the final and conclusive judgment unrighteous ones. But the writer asserts this assumption does not have considerable meaning in discussing the permission of reclaiming the proportionate amount as unjust enrichment due to the death or advancement of impaired earning capacity of injured party after the final and conclusive judgment had been adjudged and executed, as that judgment is not an unrighteous one when it was adjudged. Instead, the writer seeks the possible grounds from the jurisdiction of lawsuit of ownership transfer registration for recovery of true ownership and from the jurisdiction of lawsuit for reclaiming conspicuously increased rent–equivalent unjust enrichment owing to the skyrocketing economic circumstances.
