Kernrechtsfrage
Whether the appellants had a protected interest to seek a declaration under Art. 25a VwVG for emissions from flights directly connected with Meiringen airfield.
Extrahierter Entscheid
No separate protected interest was shown for emissions directly tied to the airfield, because those effects could be challenged in the pending sanitation proceedings.
Extrahierte Begründung
The lower court's refusal of standing on that point was upheld; the matter should be dealt with in the airfield sanitation process rather than through a separate declaratory request.
