Question juridique clé
Whether the cantonal decision on restoration of the appeal deadline was a separately appealable final decision or an interim decision.
Solution extraite
The decision was a separately issued interim decision under Art. 93 BGG, not a final decision.
Motifs extraits
The timeliness issue could still be reviewed together with an appeal against the future final decision; the case did not involve a non-appealable refusal of reinstatement treated as final.
