Extract from the Museums Act
§ The archaeological cultural heritage comprises traces of human activity left over from earlier times, i.e. structures, constructions, groups of buildings, settlements, graves and burial sites, movable objects and monuments and the context in which these traces are located.
Paragraph 2. If traces of ancient monuments are found during earthworks, the work must be stopped to the extent that it affects the ancient monument.
Paragraph 3. The Minister of Culture shall decide as soon as possible whether the work may continue or whether it shall be suspended until an archaeological survey has been carried out or until the question of acquisition under subsection (8) has been decided. No later than one year after the notification has been received, work may be resumed unless the Minister of Culture has made a recommendation on the acquisition of the ancient monument under subsection (8).
Paragraph 4. The cost of the archaeological survey shall be borne by the person on whose behalf the earthworks are to be carried out.
Paragraph 5. However, the cost shall be borne by the Minister of Culture if
(1) the cause of the survey is erosion or earthworks related thereto or earthworks carried out in the course of cultivation of ordinary agricultural crops or in the course of ordinary forestry operations, unless the operations are carried out by a State or local authority, in which case the cost shall be borne by that authority.
