Questione giuridica chiave
Whether deadline restitution should be granted against the late cantonal appeal
Decisione estratta
No; the cantonal authorities and court were entitled to refuse restitution because the appellant did not sufficiently show that the postal notice had failed and he lacked diligence.
Motivazione estratta
The Federal Tribunal found no arbitrariness in the cantonal evidentiary assessment: the registered decision was sent to the indicated address, tracking data and postal evidence supported proper deposit of the pickup notice, and the appellant's explanations were insufficient.
