Plaintiff

B The part of the judgment of the first instance, including the claim extended by this court, against the plaintiff B, is as follows.

1. The reasoning of the court's explanation concerning this case is as follows: the part of the 6th judgment of the first instance that "Plaintiff B" through No. 16 in the 14th judgment can be acknowledged that Plaintiff B delivered the 2 building of this case to the Defendant on June 19, 2020; thus, Plaintiff B is liable to pay damages for delay at the rate of 12% per annum from June 20, 2020 to the day of complete payment, with the exception that "the Plaintiff B shall be liable to pay damages for delay at the rate of 85,00,000 won per annum under the main sentence of Article 420 of the Civil Procedure Act, which is the day following the delivery of the 2 building of this case to Plaintiff B."

2. Conclusion, the plaintiffs' claim of this case should be accepted as reasonable.

As the judgment of the court of first instance is justifiable, the defendant's appeal is dismissed as it is without merit, and as the plaintiff B's claim expanded by this court is additionally accepted, the part of the judgment of the court of first instance as to the plaintiff B is modified as above. It is so decided as per Disposition.
