Question juridique clé
Whether the abstract challenge to the revised cantonal regulation was admissible and whether the appellants had standing.
Solution extraite
The appeal was admissible in principle, and the appellants had standing as persons directly or virtually affected; however, overly generic constitutional arguments were inadmissible.
Motifs extraits
The regulation was a cantonal normative act challenged within the statutory time limit. The appellants operated guest-accommodation businesses and were sufficiently affected under Art. 89 LTF. Yet the brief had to meet the specific substantiation requirements for constitutional complaints.
