Questione giuridica chiave
Whether AFU could decide incidentally on the legality of side-water uses in the sanitation proceedings.
Decisione estratta
Yes. The AFU could make a preliminary determination, and there was no arbitrariness in not awaiting a separate Regierungsrat decision.
Motivazione estratta
The sanitation was urgent, the Regierungsrat later reviewed the issue on appeal with full cognisance, and procedural economy justified not suspending the case.
