Question juridique clé
Whether the deadline for filing the appeal should be restored under Art. 50 BGG
Solution extraite
The appellant did not prove an unforeseeable, unavoidable impediment that prevented any timely action, including instructing counsel; the restoration request is rejected insofar as it is admissible.
Motifs extraits
Medical documents showed illness and treatment, but not a complete inability to act for months. A mere sick-note or even full incapacity for work is insufficient; specific proof is required that all deadline-preserving steps were impossible.
