Key legal question
Whether the federal appeal against the cantonal decision was filed within the statutory 30-day period.
Extracted holding
The appeal was late because service was deemed effective at the residential address the appellant had himself indicated in the cantonal proceedings; the notice not collected after two delivery attempts was validly served there.
Extracted reasoning
After initiating proceedings, a party must ensure valid service in good faith. The court may rely on the address indicated by the party. Here, the appellant had stated his residence in W.________ in the earlier decision and in his cantonal complaint; nothing showed that he had requested service only to a P.O. box.
