Kernrechtsfrage
Whether the cantonal court correctly held the appeal against the opposition decision to be time-barred.
Extrahierter Entscheid
Yes. With a postal retention order, the registered letter was deemed served no later than seven days after arrival at the recipient's local post office, so the cantonal appeal filed on 10 October 2012 was late.
Extrahierte Begründung
The Court held that the special service fiction for retained registered mail applies regardless of the later pickup notice or Saturday delivery habits. The relevant seven-day period started on 1 September 2012 and expired on 8 September 2012; the appeal period then ran until 8 October 2012.
