Purport of claim and appeal

1..

1. The defendant's grounds for appeal citing the judgment of the court of first instance are not significantly different from the argument in the court of first instance, and the fact-finding and judgment of the court of first instance are justified even if each evidence submitted to the court of first instance was presented to this court.

Therefore, the reasoning of this court's explanation concerning this case is as stated in Paragraph 1 of Article 420 of the Civil Procedure Act, in addition to the fact that the "Witness C" of Part II of the judgment of the court of first instance is dismissed as "the witness of the court of first instance and this court of appeal", and therefore, it is also accepted by the main text of Article 420 of the Civil Procedure Act

2. In conclusion, the Defendant is obligated to pay the Plaintiff the amount of KRW 20,000,000 and the damages for delay calculated at the rate of 15% per annum from April 25, 2017 to the day of full payment, which is the day following the delivery of a copy of the instant complaint. Thus, the Plaintiff’s claim shall be accepted on the grounds of its reasoning.

The judgment of the court of first instance is just in its conclusion, and the defendant's appeal is dismissed as it is without merit. It is so decided as per Disposition.
