Kernrechtsfrage
Whether the cantonal court correctly held the appeal against the 15 September 2009 decision to be time-barred.
Extrahierter Entscheid
Yes. The 20-day deadline under cantonal procedural law expired on 16 December 2009; the appeal filed on 17 December 2009 was late.
Extrahierte Begründung
The decision was validly served on 26 November 2009 despite missing signatures, and no grounds for restoration of time were shown.
