2. Determination

A. According to the above facts, the defendant, by occupying and using the land of this case as a road, obtained benefits without any legal grounds and suffered damages from the network E and the plaintiff C, who is the owner of the land.

In order to calculate the amount of unjust enrichment equivalent to the rent for the land possessed and used by the State or a local government as a road, the basic price of land is to be determined from the previous time by the State or a local government through construction of a road under the Road Act, etc. for the land in which the State or a local government actually used for the traffic of the general public, and is in possession of a road, and then has the form of a road as a de facto controlling entity, it shall be appraised according to the limited condition as the road, i.e., the current condition as the road, if the State or a local government occupies the land which was previously occupied and used for the traffic of the general public.
