Kernrechtsfrage
Whether the cantonal court unlawfully applied a zoning plan before its approval became legally effective.
Extrahierter Entscheid
Yes. A zoning plan becomes binding only once approved by the competent cantonal authority and that approval is final; the new plan could not be applied prematurely.
Extrahierte Begründung
The partial non-approval by the Grand Council meant the revised plan had not yet entered into force for the disputed parcels. The earlier planning zone had expired, so there was no valid basis for pre-applying the new regime.
