1. The plaintiff's claim is dismissed.

2. The costs of lawsuit shall be borne by the Plaintiff.

Comprehensively taking account of the respective descriptions and arguments in Eul evidence Nos. 1 through 12, the defendant concluded a contract for construction of KRW 14.3 million with the plaintiff for the construction cost of the D Plant Packaging Corporation (hereinafter "the construction of this case") and completed the contract.

The Plaintiff asserts that the claim against the Plaintiff was dismissed in this Court case 2015Da207066, or that the Plaintiff was extinguished by paying the construction cost of KRW 11 million to the representative director of the Defendant, and that even if not, it would be extinguished by offsetting the defective construction cost of the contractor due to the defect of the Defendant’s construction work. However, this Court’s case No. 2015Da207066, or the construction cost of KRW 11 million paid by the Plaintiff is not related to the instant construction work, and the evidence submitted by the Plaintiff alone is insufficient to acknowledge the defect of the instant construction work, and there is no other evidence to acknowledge it.

Therefore, the plaintiff's claim is dismissed as it is without merit. It is so decided as per Disposition.
