"A lack of evidence to acknowledge that the conclusion of the sales agency contract of this case was caused to the Plaintiff or that the damage was caused to the Plaintiff by the conclusion of the sales agency contract of this case, and there is no other evidence to acknowledge otherwise."

2. Judgment on the Intervenor’s application for intervention as an independent party

A. The intervenor lent KRW 200 million to the plaintiff, and at the time when the plaintiff pays KRW 150 million to the defendant as the security deposit for the sale of commercial building sales agency contract, the defendant recognized that the above KRW 150 million was part of the above loan and delivered the commercial building sales contract concerning KRW 14-5 among the commercial buildings of this case as security for the above money to the intervenor.

Therefore, when the sales agency contract between the plaintiff and the defendant is terminated, the defendant should return the sales deposit to the intervenor according to the purport of the sales agency contract.

B. The plaintiff and the defendant asserts that the application for intervention by the independent party intervenor is unlawful.

In an independent party participation, the plaintiff's principal claim and the intervenor's claim are asserted in itself.
