3. The judgment of this Court

A. 1) The term “defect in the installation or preservation of a structure” under Article 758(1) of the Civil Act related to relevant legal principles refers to a state in which a structure does not have ordinary safety according to its intended use. In determining whether such safety is satisfied, 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 resulting from a defect in the installation or preservation of a structure does not mean only a defect in the installation or maintenance of a structure causes damage, and it does not coincide with any other third party’s act or any other victim’s act.
