1. All appeals against the principal lawsuit and counterclaims filed by the Defendant (Counterclaim Plaintiff) and all appeals against the remainder of the Defendants’ principal lawsuit.

1. The grounds of appeal as to the Defendants’ principal lawsuit and the grounds of appeal as to Defendant B’s counterclaim are not significantly different from the allegations in the first instance court, and the facts established and determined by the first instance court are justified even if each evidence submitted to this court is presented to this court.

Therefore, the reasoning of the judgment of this court is the same as that of the judgment of the court of first instance, and it is accepted by the main text of Article 420 of the Civil Procedure Act.

2. The plaintiff's counterclaim against the defendants is accepted in its reasoning, and all of the counterclaims by the defendant B are dismissed as without merit. The judgment of the court of first instance is just in its conclusion, and all appeals against the defendants and the counterclaims by the defendant B are dismissed. It is so decided as per Disposition.
