1. The plaintiff's lawsuit against the defendant D apartment management office is dismissed.

2. The Plaintiff’s claim against Defendant C.

1. Whether a lawsuit against Defendant D Apartment Management Office (hereinafter “Defendant Management Office”) is lawful or not, the Plaintiff is also liable for damages against Defendant Management Office. However, Defendant Management Office is only an internal organization or organization of the council of occupants’ representatives which performs practical affairs such as the maintenance, repair, expenses, collection of management expenses, etc., and cannot be deemed as an unincorporated association or foundation. Thus, the instant lawsuit against Defendant Management Office is illegal and dismissed as it is against a person who has no capacity to sue.
