Questione giuridica chiave
Whether the cantonal court arbitrarily treated the respondents' filing as an extraordinary appeal rather than an ordinary appeal.
Decisione estratta
The cantonal court did not act arbitrarily in converting the filing and examining it as an extraordinary appeal.
Motivazione estratta
The filing was not clearly designated as an ordinary appeal, did not invoke the ordinary-appeal provision, and raised precise complaints that could be examined through the extraordinary route; nothing prevented such a conversion.
