The decision of the Council of State 2516/2009 clarifies that the act of designation of a building as dangerously dilapidated is issued by a different procedure and has different legal consequences from the act of designation of a building as merely dilapidated. Documentation as to the nature and extent of the deficiencies or damage to the building is required. A listed building may be classified as dangerously dilapidated only where the competent committee has given specific reasons for excluding the possibility of saving the building by less severe means, in which case the relevant classification act may be revoked.
