Question juridique clé
Whether the public-law appeal was admissible against the cantonal judgment upholding the fine
Solution extraite
The appeal was admissible only as a public-law appeal, and the appellants had standing as jointly fined persons.
Motifs extraits
The challenged fine was based on cantonal law; the federal occupational safety provisions referred to in the cantonal regulation were treated as part of cantonal law. Thus only the public-law appeal was open.
