A. The first floor V commercial building underground of the Seoul Jung-gu U.S. (hereinafter “U building” in the above plaintiffs’ assertion, and only the V commercial building is referred to as “V commercial building”) did not have a legitimate right to lease to the V commercial building, despite the fact that the co-owners in the white name possess the share ownership, and the defendant L did not explain the important matters under the above contract to the plaintiff G, H, I, I, and J. Accordingly, the plaintiff G, H, I, and J concluded each lease contract on the defendant L and V commercial building due to the error of the important part under the contract.

Therefore, the above plaintiffs are revoked on the ground of mistake in the above lease agreement, so the defendants are jointly and severally obligated to return money equivalent to the sale price to the original state following cancellation of the contract, and the defendant L has a duty to return money equivalent to the sale price to the original state following cancellation of the contract to the plaintiff H, I, and J.

(The above plaintiffs added the above claims to the damages claim and selectively in the trial).
