This matter is covered in sections 50 and 50a of the Border Guard Act (578/2005). The owner or holder of land or water areas within the border zone are obliged to permit i) the construction of a fence or other barrier, at the state’s expense, if this is necessary for the maintenance of border management (border barrier), ii) the construction of the barrier trail, iii) the removal of trees and other vegetation that hinder the construction and maintenance of the barrier, the barrier trail, or the border road and iv) the carrying out of essential earthmoving and water construction work.
Border barriers may not be constructed in areas of domestic peace as defined in chapter 24 and section 11 of the Penal Code. Under international agreements binding on Finland, fair compensation shall be paid to the owner or holder of the land or water area for the damage and inconvenience caused by a border barrier constructed elsewhere than at the edge of the open area at the Finnish border.
Decisions made under sections 50 and 50a can be appealed at the Administrative Court. The decisions can be enforced, however, even if such an appeal has been made.
