Purport of claim and appeal

The first instance court.

1. The court's explanation of this part of the basic facts is the same as the corresponding part, except for the fact that the "current Steel Co., Ltd." in Part II, in the column of "1. Basic facts for the reasons of the judgment of the court of first instance", and the "Witness C" in Part II, 18, and 19, shall be the same as that of the corresponding part, so it shall be accepted in accordance with the main sentence of Article 420 of the Civil Procedure Act.

2. The plaintiff's assertion and judgment

A. The plaintiff filed a claim for revocation and the claim for return of unjust enrichment on the ground of declaration of intent by duress, by threatening that the defendant cannot conclude the contract of this case or cannot continue the contract unless the defendant did not refund 500 won per ton of 1st of 1st of 1st of 1st of 1st of 1st of 200 to the plaintiff, thereby allowing the plaintiff to conclude the contract of this case in order to maintain the contract of this case. Since the plaintiff revoked it by delivery of the copy of the complaint of this case on the ground of the defendant's act of coercion, the defendant is obligated to return to the plaintiff 25,053,461 won which was received by the contract of this case on the ground of the defendant's act of coercion

B. The plaintiff asserts that the plaintiff is obligated to return the above amount by the return of unjust enrichment since the defendant used the amount of 255,053,461 won, which was paid by the plaintiff as expenses for business activities, for personal purposes, not for the agreed purpose. However, it cannot be deemed that the defendant used the amount received from the plaintiff as expenses for business activities for personal purposes, and there is no evidence to acknowledge such facts. Thus, this part of the plaintiff's assertion is without merit.
