Questione giuridica chiave
Whether the cantonal court correctly held the appeal against the IV decision to be time-barred because service occurred by 10 June 2011.
Decisione estratta
The cantonal court’s finding on service and the resulting expiry of the appeal period was not shown to be manifestly incorrect or unlawful.
Motivazione estratta
Service of an unregistered mailing is a factual question reviewed only for manifest error; the administration bears the burden of proving service, but in case of dispute the recipient’s account prevails only if one is given. Here the appellant offered no concrete account of receipt, while the surrounding circumstances supported delivery by 10 June 2011.
