Kernrechtsfrage
Whether the federal complaint meets the requirements for substantiation under Art. 42(2) BGG
Extrahierter Entscheid
The complaint did not sufficiently explain why the cantonal court's deemed-service reasoning was incorrect.
Extrahierte Begründung
The appellant merely asserted non-receipt and did not address the cantonal court's reasoning that he had to expect service and therefore bore responsibility for the failed postal delivery.
