Questione giuridica chiave
Whether the appeal was filed within the statutory 20-day period under Art. 30 OG.
Decisione estratta
The appeal was untimely because it had to be lodged with the competent cantonal court within 20 days of service; mailing or signing within time was insufficient.
Motivazione estratta
Service was proved to have occurred on 1888-05-16. The appeal declaration reached the cantonal court only on 1888-06-06, the 21st day after service, so the deadline had expired.
