1. All appeals by the Plaintiffs, the Plaintiff’s successor, and the Defendant are dismissed.

2. The costs of appeal shall be borne respectively by each party.

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

Therefore, the reasoning for the court’s explanation on the instant case is as stated in the reasoning of the judgment of the first instance, except for the case where the 4th of the judgment of the first instance is “resident” under the 5th of the judgment of the court of first instance, and thus, it is also cited by the main sentence of Article 420 of the Civil Procedure

2. Thus, the claims of the plaintiffs and the plaintiff succeeding intervenor are accepted within the scope recognized by the court of first instance, and the remaining claims are dismissed as they are without merit. Since the judgment of the court of first instance is justified with this conclusion, all appeals by the plaintiffs, the plaintiff succeeding intervenors, the defendant are dismissed as they are without merit. It is so decided as per Disposition.
