Questione giuridica chiave
Whether the federal court should quash the cantonal judgment ordering restoration of lawful use of the room.
Decisione estratta
The cantonal judgment was upheld because the challenged use had never been approved and the restoration order was based on prior final municipal decisions.
Motivazione estratta
Earlier building permits and later amendment decisions repeatedly left the restrictive condition unresolved; the enforcement order merely enforced an existing, final land-use restriction.
