2. The plaintiff's assertion

A. The Plaintiff, as a matter of principle, was aware that the existing building management ledger was not available to obtain a building permit as to the instant land, which is a development restriction zone. However, the Plaintiff believed that the construction permit could be exceptionally granted because there was a special circumstance where the previous airline, fire proof center, and neighboring residents, which could have known that the previous building had been destroyed by fire, had been destroyed by a fire.

The plaintiff asked the defendant B to find out whether the building permit can be legally granted for the exceptional reasons as above, under the premise to conclude the construction contract on the land of this case with the defendant B.

Defendant B confirmed that Defendant C’s employees D cannot obtain a building permit for the instant land.

Nevertheless, Defendant B received KRW 35,00,000 as if it were cost of construction since it was delegated by the Plaintiff to the Plaintiff that it did not inform the Plaintiff of the truth and could legally obtain building permission in order to receive construction permission.

Furthermore, Defendant B, in collusion with D, obtained the instant permission to engage in the instant act in an unlawful manner in collusion with the public official in charge and modifying the building management ledger of other lot number land, and entered into a contract for construction works with the Plaintiff.
