Questione giuridica chiave
Whether the Federal Supreme Court could review the cantonal court's non-entry decision on the dentist's complaint.
Decisione estratta
Only the non-entry ruling was reviewable; the court could not examine the substantive declaratory request directly.
Motivazione estratta
The appeal was directed against a procedural non-entry decision, so federal review was limited to whether the lower court correctly refused to hear the case.
