Kernrechtsfrage
Whether the appeal period should be restored under Art. 50 BGG
Extrahierter Entscheid
No. The filing mistake was attributable to counsel's office and was therefore not excusable.
Extrahierte Begründung
Restitution requires an unavoidable impediment; the appellant's own admission showed the omission of the appeal was due to an error by the lawyer or his office, which is imputable to the party.
