Questione giuridica chiave
Whether the federal appeal was filed within the statutory time limit.
Decisione estratta
No. The appeal was filed after the 30-day deadline had expired and was therefore inadmissible.
Motivazione estratta
The cantonal judgment was delivered on 2013-02-20; under Arts. 44, 47 and 100 LTF the deadline expired on 2013-03-22. Filing on 2013-04-29 was manifestly late, and transmission via the cantonal court caused no prejudice under Art. 48(3) LTF.
