Kernrechtsfrage
Whether the federal appeal was filed within the deadline despite postal service fiction.
Extrahierter Entscheid
The appeal was timely because the seven-day fiction under Art. 44 BGG begins only after the first failed delivery attempt; there is no duty to collect mail earlier.
Extrahierte Begründung
The respondent did not show that counsel actually collected the decision before the last day of the pickup period. Mere ability to collect earlier does not make waiting abusive.
