Questione giuridica chiave
Whether the federal appeal is admissible despite non-payment of the requested advance on costs.
Decisione estratta
No; the appeal is inadmissible because the appellant failed to pay the advance within the time limits set, despite a warning.
Motivazione estratta
Under Art. 62 para. 3 LTF, failure to pay the advance on costs within the prescribed time permits the court to decline to hear the appeal; the matter was therefore handled in simplified procedure under Art. 108 para. 1(a) and para. 2 LTF.
