Questão jurídica principal
Whether the appeal period should be restored under Art. 50 BGG
Decisão extraída
No. The filing mistake was attributable to counsel's office and was therefore not excusable.
Fundamentação extraída
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.
