Kernrechtsfrage
Whether the appeal was timely and could be supplemented after the deadline.
Extrahierter Entscheid
The additional filing of 23 November 2012 was out of time and could not be considered; the 16 November 2012 filing was not properly completed within the appeal period.
Extrahierte Begründung
The 30-day appeal period had expired on 16 November 2012. A later submission cannot cure the lack of complete reasoning within the statutory deadline.
