Questione giuridica chiave
Whether the cantonal court acted arbitrarily by finding that the cost advance was not paid in time and therefore refusing to hear the appeal.
Decisione estratta
The challenged non-entry decision was not arbitrary; the evidence submitted did not establish timely payment of the advance.
Motivazione estratta
Only a poor photocopy of a postal receipt supported the claim, while the cantonal court's account records showed no matching payment. The complainant did not produce the original receipt or a clear postal or company confirmation, although such proof would have been readily available.
