The defendant's KRW 172,762,477 as well as 6% per annum from December 13, 2019 to June 23, 2020.

Comprehensively taking account of the overall purport of the statements and arguments set forth in subparagraphs A and 2, the Plaintiff may recognize the fact that the Plaintiff issued an electronic tax invoice of KRW 1,986,762,770 (including value-added tax; hereinafter the same shall apply) in total with respect to the construction cost and equipment rent (hereinafter “construction cost, etc.”) to the Defendant during the period from August 2014 to October 2019 as shown in the attached Table.

According to the above facts, the defendant is obligated to pay to the plaintiff the amount of KRW 1,814,00,293 less the amount of KRW 1,812,762,777, which the plaintiff paid from the defendant in aggregate of KRW 1,986,762,770, including the construction cost of this case, and the damages for delay calculated at each rate of 6% per annum under the Commercial Act from December 13, 2019 to June 23, 2020, which is the day following the delivery date of the original copy of the payment order of this case, and as the plaintiff seeks, from December 13, 2019 to June 23, 2020.

In addition to the instant construction cost, the Plaintiff sought payment of KRW 12,474,00,00 for construction cost or equipment rent, which did not issue an electronic tax invoice. However, the evidence submitted by the Plaintiff alone is insufficient to recognize the existence of the above construction cost or equipment rent claim, and there is no evidence to acknowledge otherwise, the Plaintiff’s assertion on this part is without merit.

Therefore, the plaintiff's claim is justified within the above scope of recognition, and the remaining claims are dismissed as it is without merit. It is so decided as per Disposition.
