Question juridique clé
Whether the federal appeal was filed within the statutory time limit or whether the deadline should be restored.
Solution extraite
The appeal was filed late; no grounds for restitution were given, so the deadline could not be restored.
Motifs extraits
The cantonal judgment was received on 11 September 2013, making the 30-day federal deadline expire before the filing on 4 December 2013. No excusing reason was invoked under Art. 50 BGG.
