3. Determination as to the defendants' defense

A. The assertion: (a) According to Article 17(5)3 of the Enforcement Rule of the former Housing Act and Article 23(1)3 of the Rules of the D Regional Housing Association, where a “contract that will be borne by members, other than the matters stipulated in the budget,” is concluded, it shall undergo a resolution of ratification by the general meeting of the association members. The instant agency contract concluded without going through such procedures is null and void because it violates the Housing Act, which is a mandatory provision, or violates the Defendants’ delegation of authority.

② Even if the instant agency contract is valid, the D Regional Housing Association already paid to the Plaintiff the administrative service cost in excess of the administrative service cost for the actual service duties performed by the Plaintiff.

③ The Plaintiff owes its obligations to the D Regional Housing Association, the primary debtor of the instant administrative service costs, in accordance with the instant undertaking.
