Questione giuridica chiave
Whether Bigler's appeal to the Federal Court was filed within the statutory 20-day period
Decisione estratta
The appeal was late because it reached the cantonal court only on the 21st day after service; posting the letter earlier did not suffice.
Motivazione estratta
Art. 30 O.G. requires the appeal declaration to be filed with the cantonal court within 20 days. Filing is complete only when the declaration has reached that court.
