Key legal question
Whether R.'s late filing could be restored or deemed timely
Extracted holding
No. The court found no unconstitutional or arbitrary refusal to restore the time limit for R.; the missed deadline remained attributable to the representative's fault.
Extracted reasoning
The notice on the envelope ('Avis 4.5.06') did not justify assuming a later service date, and the representative's inability to understand or notice it amounted to culpable negligence under cantonal law.
