Seoul High Court Decision 90Na34122 delivered on April 12, 1991

The appeal is dismissed.

The costs of appeal are assessed against the plaintiff.

1. Regarding ground of appeal No. 1

The court below's rejection of the plaintiff's assertion that the plaintiff and the defendant agreed to postpone the payment date of the remainder of this case is without merit.

2. Regarding ground of appeal No. 2

According to the reasoning of the judgment below, the plaintiff and the defendant, who is the agent of the non-party 1, obtained a certificate of personal seal impression for the above real estate on February 24, 1989, and issued a certificate of personal seal impression for 90 million won for the above real estate on the contract date, and the intermediate payment of 40 million won can be paid with the required documents for the transfer of ownership on August 30 of the same year. The provisional registration under the name of the non-party 2, which was completed part of the real estate of this case, was made before the intermediate payment was cancelled, and the above down payment was not paid on the day of the above contract date. The plaintiff, the plaintiff, the defendant, and the non-party 1, who did not pay the intermediate payment on June 14 of the same year because they did not have the above obligation to cancel the above provisional registration because they did not have the above obligation to purchase and sell the above real estate by the non-party 1, the plaintiff's wife and the above non-party 2, who did not have the above obligation to cancel the contract.

In light of the principle of good faith, the court below did not err as the theory of facts in the court below's finding of facts, and it is reasonable to see that the defendant provided the performance of one's own obligation even though it is not complete in light of the principle of good faith. On the other hand, the plaintiff's preparation of half of the intermediate payment and the remaining amount in the statement of shares per share cannot be deemed to have provided the performance of his own obligation. Therefore, it is reasonable to determine that the sales contract of this case was automatically cancelled according to the above agreement of June 14, 198 (see Supreme Court Decisions 87Da2739, 2740, Dec. 6, 198; 91Da13120, Aug. 23, 191; 8Da2891, Jul. 25, 1989).

3. Accordingly, the appeal shall be dismissed, and all costs of appeal shall be assessed against the plaintiff who has lost. It is so decided as per Disposition by the assent of all participating Justices.
