Question juridique clé
Whether a direct federal appeal was admissible without exhausting cantonal remedies against the cantonal normative act.
Solution extraite
A direct appeal was admissible because a cantonal remedy was at least highly doubtful and not clearly available for a regulation adopted by the cantonal court.
Motifs extraits
The constitutional court route was not plainly open to review acts of the cantonal court, and the neutral court had no general competence to hear the merits absent a recused competent authority.
