Kernrechtsfrage
Whether the administrative law appeal was admissible against a cantonal decision on expiry of a building permit
Extrahierter Entscheid
The administrative law appeal was inadmissible because the dispute concerned only the duration and lapse of the permit under cantonal procedural law, not directly applicable federal law.
Extrahierte Begründung
The Court held that the permit-duration rules were essentially cantonal procedural law; only the public-law appeal was available for such exclusively cantonal issues.
