Question juridique clé
Whether the appeal was admissible without prior cantonal remedies against the cantonal tariff
Solution extraite
Direct federal review was available because any cantonal remedy was at least seriously doubtful, and exhaustion was therefore not required.
Motifs extraits
The constitutional court route was not clearly open for a tariff adopted by the cantonal court itself, and the neutral court had no general competence to hear such a challenge absent recusals.
