[Ground of recognition] Facts without dispute, entry of Gap 1 to 3 evidence, purport of the whole pleadings

2. Claim:

A. Defendant B and C notified the Plaintiff of the details of the lease and the details of the lease of the illegal alteration of the purpose of the use thereof falsely, and did not notify the Plaintiff of any part of the 2,3,6, and7 stories registered as neighborhood living facilities of the illegal alteration of the purpose of the use thereof as residential facilities. The Plaintiff was revoked the instant sales contract on the grounds of deception or mistake by the Defendants. Therefore, the Defendants are liable to pay the Plaintiff the purchase price of KRW 90 million paid by the Plaintiff as compensation for damages or return of unjust enrichment, and damages for delay thereof. 2) The instant sales contract was revoked by agreement with the first police officer on May 2016.

Even if the agreement is not rescinded, so long as the Defendants sold the instant building to a third party and completed the registration of transfer, the instant sales contract became impossible to perform.
