1. All appeals filed by the Defendant (Counterclaim Plaintiff) against the principal lawsuit and counterclaim are dismissed.

2. The appeal costs.

The reasoning for the court's explanation on this case is that "the defendant's damage claim against the plaintiff" in Part 14 of the judgment of the court of first instance is "the defendant's damage claim against the plaintiff due to the plaintiff's non-performance or illegal act", and the "damage compensation due to the plaintiff's illegal act" in Part 20 and 21 of the judgment of the court of first instance is the same as "damage compensation due to the plaintiff's non-performance or illegal act", and therefore, it is cited in accordance with

If so, the judgment of the first instance court is justifiable, and the defendant's appeal is dismissed as it is without merit.
