1. All appeals filed by the Defendant (Counterclaim Plaintiff, the appointed party) are dismissed.

2. The appeal cost is the Defendant-Counterclaim Plaintiff.

The court's explanation of this case is the same as the corresponding part of the judgment of the court of first instance, and thus, citing this case in accordance with the main sentence of Article 420 of the Civil Procedure Act.

2. In conclusion, the plaintiff's main claim is accepted within the scope of the above recognition, and the remaining claims are dismissed as without merit, and the defendant's counterclaim is dismissed as it is without merit. The judgment of the court of first instance is just in conclusion. Thus, all of the defendant's appeal is dismissed, and the remaining claims against the plaintiff's designated representative C are dismissed. Since it is obvious that the plaintiff's remaining claims against the plaintiff's designated representative C and the counterclaim claims against the defendant (Counterclaim plaintiff and the designated party) are all written errors in the judgment of the court of first instance, each of them is corrected. It is so decided as per Disposition.
