Key legal question
Whether administrative judicial review was available for the challenged opening-hours restriction and whether subsidiary constitutional appeal was barred
Extracted holding
The administrative appeal was admissible because the decision was based on federal environmental law and sufficiently related cantonal rules; the constitutional appeal had no separate room.
Extracted reasoning
The challenged decision applied USG and LSV together with cantonal hospitality rules. Where cantonal law concerns noise protection and has a close connection to federal environmental law, administrative judicial review lies. Constitutional complaints cannot proceed separately on the same reviewable issues.
