Questione giuridica chiave
Whether the appeal is admissible despite non-payment of the requested advance costs after a grace period.
Decisione estratta
The appeal is inadmissible because the appellant failed to pay the advance costs even after the additional time limit.
Motivazione estratta
Under Art. 62 para. 1 and 3 LTF, failure to pay the required advance costs within the additional period makes the appeal inadmissible; the court therefore declined to enter on the appeal under Art. 108 para. 1 let. a LTF.
