1. The appeal against the counterclaim by the Plaintiff (Counterclaim Defendant) and the Defendant’s succeeding intervenor (Counterclaim Plaintiff) and the Defendant’s succeeding intervenor.

1. The grounds for appeal by the plaintiff, the defendant succeeding intervenor, and the defendant succeeding intervenor are not significantly different from the allegations in the first instance court, and the fact-finding and decision of the first instance court are justified even if each evidence submitted in the first instance court was presented to this court.

Therefore, the reasoning of the judgment of this court is identical to the reasoning of the judgment of the court of first instance.

2. In conclusion, the judgment of the court of first instance is legitimate, and all appeals filed against the plaintiff's counterclaim and appeals filed against the defendant's succeeding intervenor and the defendant's succeeding intervenor are dismissed.
