Question juridique clé
Whether the federal administrative court complaint was admissible against the cantonal refusal to hear the neighbor's appeal
Solution extraite
Yes. In a federal-law matter, the cantonal non-entry decision could be challenged by administrative court complaint, and standing had to be ensured to the same extent as in federal proceedings.
Motifs extraits
The permit relied on federal environmental protection rules, so the matter was governed by federal administrative law. A cantonal procedural refusal that prevents review of federal law may be attacked before the Federal Supreme Court.
