On March 31, 2016, A entered into a sales contract with the Defendant with the purchase price of KRW 839,474,880 (the purchase price of KRW 83,947,480, the intermediate payment of KRW 162,45,70, the remainder of KRW 430,616,00, each of which is KRW 162,45,70, and the intermediate payment of KRW 408,888,880, the down payment and the intermediate payment of KRW 408,880,00 to the Defendant.

Plaintiff

B entered into a sales contract (hereinafter collectively referred to as “each of the instant sales contracts”) with the Defendant on the same day with the sales price of KRW 806,040,850 (the contract amount of KRW 80,604,080, the intermediate payment of KRW 155,985,510, and the remainder of KRW 413,465,750) for the first floor F of the instant building, and the Defendant paid the Defendant the down payment and the intermediate payment of KRW 392,575,10 in total.

[Grounds for recognition] The facts without dispute, Eul evidence 1-1 and 2, and the purport of the whole argument of the parties concerned at the time of entering into each of the sales contracts of this case, the defendant explained to the plaintiffs that "the first floor commercial building, which is a neighborhood living facility, is a space-type commercial building created to allow customers to walk at a distance and walk at a distance or to find food," and for this purpose, the defendant also tried to enter into each of the sales contracts of this case, stating that there are no stairs at the front of the building F and E of this case, and that there is no stairs at the entrance, and that there is no design indicating that the stairs should be installed at the entrance of the corridor connecting the elevator at the entrance, and that each of the sales contracts of this case was installed at the front of the E store. Accordingly, the plaintiffs concluded each of the sales contracts of this case.

However, in the front of the instant building F, the Defendant installed three stairs of a group, and installed four stairs of a group in the front of E.

The Plaintiffs made an error that they would purchase a "sast-type shopping mall" that minimizes stairs entirely in accordance with each of the instant sales contracts, which is an error of motive caused by the Defendant, and is a juristic act.
