Questione giuridica chiave
Whether the cantonal department wrongly refused to hear the administrative appeal as time-barred after deemed service.
Decisione estratta
The department could rely on deemed service; the appeal was late and no ground for restoring the deadline was shown.
Motivazione estratta
After initiating the proceedings, the complainant had to ensure receipt of official mail. He was absent, did not notify the authority, and did not arrange for valid receipt by his brother. The service fiction and the resulting non-entry did not violate constitutional rights.
