Question juridique clé
Whether the municipality had standing to bring the administrative law appeal
Solution extraite
Yes. Although it was not acting as a private landowner, the municipality was entitled to appeal under Art. 57 USG because it was affected in its public duties and had a protectable interest in protecting the population from harmful radiation.
Motifs extraits
A commune may appeal when a federal environmental decision touches its sovereign tasks. The municipality's failure to participate as landowner in the cantonal proceedings meant it could not rely on that private-law position, but its environmental protection task justified standing.
