Questione giuridica chiave
Whether the cantonal court rightly declined to hear the appeal because it was filed late
Decisione estratta
Yes. The complaint was admittedly filed too late, and the cantonal court therefore correctly declined to enter into the merits.
Motivazione estratta
The deadline had expired before mailing. Only a successful reliance on good faith could justify treating the appeal as timely, but the prerequisites were not met.
