2. Determination as to a claim for return of unjust enrichment (principal claim)
A. The Plaintiff’s assertion that the Defendant: (a) transferred KRW 34,944,854 to the account in the name of the Defendant due to the Defendant’s act of hosting the name in the name of the boxes; and (b) recovered KRW 25,950,894,00 without any legal cause (i.e., KRW 34,94,944,854 - KRW 25,950,894 - KRW 2594); and (b) thereby, the Plaintiff suffered damages equivalent to the same amount; and (c) accordingly, the Defendant is liable to return to the Plaintiff the amount of KRW 8,94,00 as unjust enrichment.
B. (1) Even though there is no legal relationship between a remitter and an addressee as the cause of the account transfer, in cases where an addressee acquires a deposit claim equivalent to the amount of account transfer by account transfer, the remitter is entitled to claim the return of unjust enrichment equivalent to the above amount against the addressee (see, e.g., Supreme Court Decision 2007Da51239, Nov. 29, 2007). Meanwhile, the unjust enrichment system imposes the duty of return on the benefiting person on the basis of the principle of fair justice in cases where the benefiting person’s property gains have no legal cause.
