Key legal question
Whether the administrative appeal was admissible alongside the subsidiary constitutional complaint
Extracted holding
The administrative appeal was admissible because the permit should also have been assessed under federal environmental law; the zoning complaint remained reserved for constitutional review.
Extracted reasoning
The project involved immission issues governed by the USG and LSV, which deprived the relevant cantonal noise rules of independent significance. By contrast, the zoning issue under Art. 13 BauR concerned autonomous cantonal law without a sufficient link to federal administrative law.
