Kernrechtsfrage
Whether the appellants had standing to challenge the building permits/non-entry decision under RPG, BGG and cantonal procedure law.
Extrahierter Entscheid
Standing depends on concrete special affectedness and a protectable interest; in building cases, distance and visibility are not decisive by themselves. Emissions from traffic or operation can confer standing only if they are sufficiently perceptible and the appellants are meaningfully affected. Here, the appellants were not sufficiently affected by the east-side operation or by the limited additional traffic to the building No. 1.
Extrahierte Begründung
The court applied Art. 33(3)(a) RPG and Art. 89(1) BGG, holding that cantonal law must afford standing at least to the extent required federally. It emphasized a case-by-case overall assessment, not rigid distance or sightline tests. For the east-side operation, the distance was large and the remaining traffic passing the appellants’ property was negligible compared with the last permitted use. For building No. 1, the reference baseline was the last authorised use, not the period of business shutdown; the alleged additional traffic and direct impacts were insufficiently shown.
