Questão jurídica principal
Whether the cantonal court arbitrarily treated the respondents' filing as an extraordinary appeal rather than an ordinary appeal.
Decisão extraída
The cantonal court did not act arbitrarily in converting the filing and examining it as an extraordinary appeal.
Fundamentação extraída
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.
