Questione giuridica chiave
Whether the public-law appeal could challenge the first-instance ruling as well as the cantonal appellate judgment.
Decisione estratta
The complaints directed at the first-instance judge were inadmissible; only the last cantonal decision could be attacked.
Motivazione estratta
No exception allowed a direct challenge to the lower-instance ruling because the cantonal appellate court could review all issues and had no narrower power than the Federal Tribunal.
