Kernrechtsfrage
Whether the appeal was timely despite the cantonal judgment notification date and the judicial holidays.
Extrahierter Entscheid
Only the filing of 10 January 2013 was timely; the supplementary submission of 22 January 2013 was late because the appeal period had expired on 15 January 2013.
Extrahierte Begründung
Under the LTF, legal deadlines are suspended from 18 December to 2 January. Counting from notification on 30 November 2012, the 30-day appeal period ended on 15 January 2013.
