Questione giuridica chiave
Whether the cantonal appeal was filed within the 20-day deadline.
Decisione estratta
The appeal period began when the appellant received the challenged order on 2009-10-16; filing on 2009-11-13 was therefore late.
Motivazione estratta
Receipt of the appealable order triggers the deadline. Subsequent correspondence with the first-instance court does not alter the start of the time limit.
