Kernrechtsfrage
Whether the federal appeal against the cantonal disability insurance judgment was filed in time and is admissible
Extrahierter Entscheid
The appeal was filed after expiry of the 30-day time limit and the appellant did not prove timely postal filing.
Extrahierte Begründung
The deadline ran from the day after service and, after taking account of the Easter court recess, expired on 19 April 2007. The burden of proving timely filing lay on the appellant. The documents produced showed that the disputed submission was posted on 20 April 2007; the handwritten correction and postal stamp confirmed this. No further evidence was required because the file already made timely filing impossible to establish with full proof.
