Questão jurídica principal
Whether the appeal was admissible before the Federal Supreme Court despite the building-permit question being governed mainly by cantonal law.
Decisão extraída
Yes. The complaint was admissible because the appellant alleged that the lack of a permit procedure would prevent review and enforcement of federal environmental law, and he had neighbor standing.
Fundamentação extraída
A cantonal procedural decision can be reviewed by administrative appeal if it may thwart the application of federal law; a neighbor of the affected facility is legitimized.
