Question juridique clé
Whether the public-law appeal was admissible against the cantonal decision imposing administrative fines under cantonal law.
Solution extraite
The appeal was admissible as a public-law constitutional complaint because the sanctions rested exclusively on cantonal law and the appellants had a current, legally protected interest.
Motifs extraits
Only constitutional review was available; the appellants were directly affected by the confirmation of the fines and therefore had standing.
