[Ground of recognition] Facts without dispute, entry of Gap evidence 1 to 3, and evidence 8, and the purport of the whole pleadings

2. Judgment as to the main claim

A. The Plaintiff alleged that the instant building was defective, such as beeras, beer room, water leakage in multi-use rooms, wall cracks, damage to the floor floor in front of the toilet, etc. As a result, the balcony was illegally expanded and thus an administrative agency may impose a corrective order, a non-performance penalty, etc., on the Plaintiff. Even if there were defects such as water leakage in the future through a meeting among the occupants of Bara, the Defendants did not notify the Plaintiff of such fact at the time of the instant sales contract.

If the plaintiff knew the above facts, he did not conclude the sales contract of this case, but did not enter into the sales contract of this case by deceiving the defendants, so the plaintiff would cancel the sales contract of this case on the ground of deception.

Therefore, Defendant B shall transfer the ownership of the purchase price of KRW 160,000 as the return of unjust enrichment to the Plaintiff, and the compensation for damages caused by illegal acts.
