Questione giuridica chiave
Whether the subsidiary constitutional complaint was admissible against the cantonal decision and against the first-instance ruling as well.
Decisione estratta
Only the final cantonal decision could be challenged; the challenge to the first-instance legal-opening order was inadmissible.
Motivazione estratta
A subsidiary constitutional complaint lies only against final cantonal decisions. The lower-instance ruling was therefore not reviewable before the Federal Supreme Court.
