Questione giuridica chiave
Whether the appeal had to be declared inadmissible because the required advance on costs was not paid in time.
Decisione estratta
Yes. Since the advance on costs was not paid within the deadlines set, the appeal was inadmissible under Art. 62(3) LTF.
Motivazione estratta
The court noted the initial order requiring a CHF 500 advance and the subsequent extension of the deadline. Because payment was not made within the time limit, the statutory consequence of inadmissibility followed.
