Kernrechtsfrage
Whether the federal appeal was filed within the statutory time limit.
Extrahierter Entscheid
No; the appeal period had already expired by 10 March 2008, so the filing on 30 April 2008 was late.
Extrahierte Begründung
Service by failed registered delivery was deemed completed on the seventh day after the first unsuccessful attempt; the appeal period then began the next day and ended on the next working day.
