2. Determination as to the cause of action

A. Generally, the establishment of the right to claim restitution of unjust enrichment can be divided into possession and possession as the de facto controlling body of the road management authority. Thus, if the existing road is determined by the Road Act, or the road zone is constructed by the implementation of the urban planning project under the Urban Planning Act, possession as the road management authority starting from the existing existing road can be recognized. Even if the road is not established by the Road Act, if the State or a local government actually performs the reconstruction or maintenance of the existing road, such as expansion of the existing road, road packing, or installation of sewerage system, and uses it for the general public’s traffic, it can be recognized that the existing road is under the de facto control of the State or the local government, and that the occupation as the de facto controlling body has commenced.
