1. The plaintiff (appointed party)'s appeal is dismissed.

1. The reasoning of the judgment of the court of first instance citing this case is that the part of the reasoning of the judgment of the court of first instance excluding the part of 16, 16, 17, and 14, which are written in the following, is as stated in the reasoning of the judgment of the court of first instance. Thus, this part is cited in accordance with the main sentence of Article 420

The right to claim compensation for defects and the right to claim compensation for defects held against the contractor by the council of occupants' representatives under the former Multi-Family Building Act and the Housing Act and subordinate statutes are completely different from each other (see, e.g., Supreme Court Decisions 2009Da23160, Sept. 13, 2012; 2009Da3405, Mar. 24, 201; 2010Da41928, Mar. 14, 2013; 2010Da41928, etc.). Furthermore, since the contractor’s right to claim compensation for defects and the right to claim compensation for defects held against the contractor by the council of occupants' representatives against the project undertaker under the former Multi-Family Building Act and the Housing Act and subordinate statutes, the right to claim compensation for defects and the right to claim compensation for defects are also separate from each other (see, e.g., Supreme Court Decision 2009Da23401, Mar. 2015). 206.
