The official reply on approving the public premise demolition made by an administrative organ is in nature a legally binding decision on how to handle the premises, and the fact that who is the subject of the act enforcing the specific demolition, namely who completed the demolition task involved in the case, does not affect the disposition effectiveness of the legal act in the form of the official reply to the premises involved. The claim by an administrative counterpart to confirm that the act of the premise demolition is illegal should be construed as, among others, an objection to the official reply given by the administrative organ, which constitutes the subject matter of the administrative action.
