Kernrechtsfrage
Whether the administrative complaint and parallel constitutional complaint were admissible
Extrahierter Entscheid
The administrative complaint was admissible; the constitutional complaint was not, because all admissible grievances could be heard in the administrative complaint procedure.
Extrahierte Begründung
The cantonal judgment concerned a federal planning-law exception permit and relied mainly on federal environmental law, so administrative judicial review was open. The parallel constitutional complaint was unnecessary.
