Kernrechtsfrage
Whether the administrative-law appeal was admissible against the quarry extraction plan.
Extrahierter Entscheid
Admissible only insofar as federal environmental-law issues were raised; other planning-law grievances were outside this remedy.
Extrahierte Begründung
A plan of extraction is a land-use plan; under Art. 34 LAT ordinary planning objections go by public-law appeal, but where federal environmental rules are at issue, administrative-law appeal is open.
