2. Determination

A. According to the facts found in the judgment on the cause of claim, the Defendant is obligated to pay the Plaintiffs the remaining sales amount of KRW 40 million ( KRW 70 million - KRW 630 million - KRW 30 million) and delay damages, which have been paid pursuant to the instant sales contract.

B. On the Defendant’s assertion, the Defendant recognized the installation cost of each of the instant real estate leased to operate an industrial company and agreed to reduce the purchase price of KRW 40 million, and accordingly, asserted that the remainder of the purchase price to be paid to the Plaintiffs does not remain.

However, even according to H’s testimony, the purport of this case’s contract was that there was a reference for reduction in the amount of the purchase price, which is the most important part of the contract, to the parties to the contract, if there was a change in the amount of the purchase price.
