2. Determination as to the cause of claim

A. “Defects of installation or preservation of a structure” under Article 758(1) of the Civil Act refer to the state in which a structure fails to meet the ordinary safety requirements according to its use. In determining whether such safety requirements are met, it shall be determined on the basis of whether the installer or custodian of the structure has fulfilled his/her duty to take protective measures to the extent generally required by social norms in proportion to the risk of the structure (see, e.g., Supreme Court Decision 2008Da61615, Feb. 11, 2010). Moreover, an accident caused by a defect in the installation or maintenance of a structure causes only the defect in the installation or maintenance of the structure.
