Kernrechtsfrage
Whether the remedial order based on Art. 30 LPNMS violated the property guarantee and proportionality principle.
Extrahierter Entscheid
The order was proportionate: the owner had to comply with the binding 2001 authorization, the deviation was not minor, the public interest in protecting the monument prevailed, and the financial burden was not excessive.
Extrahierte Begründung
The owner did not challenge the 2001 authorization in time and did not show grounds for revisiting it. The contested order concerned only parts of the building still governed by the original conditions. The cantonal court was entitled to require compliance with those conditions.
