Question juridique clé
Whether the cantonal court violated the right to be heard by imposing operating-hour restrictions without prior discussion.
Solution extraite
No. The restrictions were foreseeable, the court applied the law ex officio, and the parties had an opportunity to comment after further evidence was taken.
Motifs extraits
A judge may consider emissions-limitation measures under federal environmental law without separately inviting the parties to comment when such a legal basis is foreseeable in the dispute and the parties were able to be heard on the relevant facts.
