(2) Article 208(3)3 of the Civil Procedure Act applies only to the part on confirmation of existence of the obligation: (a) the Plaintiff paid KRW 2,025,340 to the Deceased for hospital treatment expenses due to a traffic accident by public notice; (b) the Defendants, the legal heir of the Deceased, claiming that the above amount should be returned as unjust enrichment according to their own shares of inheritance; (c) it is difficult to find the Plaintiff to have no legal grounds for the amount paid to the Deceased. Rather, the evidence presented to this court alone is recognized as having no legal grounds for the amount paid to the Deceased. Rather, the Deceased, as to the part on the claim for return of unjust enrichment, was subject to contact with the Deceased at the time of the instant accident, by taking into account the following circumstances acknowledged by the overall purport of each of Gap evidence, Eul evidence Nos. 1, 2, and 3 (data submitted by the deceased) and all of the arguments, i.e., the Deceased’s wheel, even if the Deceased suffered an injury only from the deceased’s body’s wheel at the time of the deceased’s body.
