Kernrechtsfrage
Whether the administrative appeal was admissible and the public-law appeal subsidiary
Extrahierter Entscheid
The administrative-law appeal was admissible; the public-law appeal was subsidiary and therefore inadmissible.
Extrahierte Begründung
The project was a concrete cantonal land-use plan closely linked to federal environmental law, so review under administrative law was available and covered the constitutional grievances as well.
