Questione giuridica chiave
Whether the cantonal court correctly struck the appeal off the roll for non-payment of the ordered cost advance.
Decisione estratta
The appeal was properly treated as discontinued because the cost-advance order was deemed served and the advance was not paid within the deadline.
Motivazione estratta
A registered cost-advance order was notified by pickup notice, the appellant had to expect procedural instructions because he had filed the appeal, and under service fiction the notice was deemed served at the end of the collection period. The appellant's objections did not undermine the postal evidence or require parallel service by ordinary mail.
