Key legal question
Whether the federal public-law appeal was admissible while a cantonal deadline-restoration request was still pending.
Extracted holding
No. The appellant had to await the cantonal decision on deadline restoration before seizing the Federal Supreme Court.
Extracted reasoning
Deadline restoration under cantonal law is a complete cantonal remedy that must be exhausted first; the Federal Supreme Court would otherwise decide the issue as a first instance and could only review limited constitutional questions.
