1. The Defendant shall pay to the Plaintiff KRW 22,10,000 and the interest rate of KRW 20% per annum from December 4, 2014 to the day of complete payment.

In full view of the purport of the entire pleadings in each entry in Gap 1-1 and 1-2, the facts of the reasons for the claim are recognized.

Therefore, the Defendant is obligated to pay to the Plaintiff 22,10,000 won with 20% interest per annum under the Act on Special Cases Concerning the Promotion, etc. of Legal Proceedings from December 4, 2014 to the date of full payment, as the Plaintiff seeks.

The defendant asserts to the effect that "the products installed between the plaintiff and the defendant were traded on the condition that there is no defect in the products installed, and all the products supplied by the plaintiff can not be used as defective products, so it cannot respond to the plaintiff's claim for the price of the goods."

Therefore, it is recognized that each receipt (A-1, 1-2) delivered by the Defendant to the Plaintiff by the Defendant stated the phrase “the product is not defective at the time of being installed,” but there is no evidence to acknowledge that there was a substantial defect in the product supplied by the Plaintiff to the Defendant.

Therefore, the defendant's above assertion is not accepted.

Therefore, the plaintiff's claim of this case is reasonable, and it is so decided as per Disposition.
