Questione giuridica chiave
Whether the appeal was admissible despite non-payment of the advance of costs within the additional deadline.
Decisione estratta
No. Because the appellant failed to comply with the extended deadline, the appeal had to be declared inadmissible.
Motivazione estratta
Under Art. 62 para. 3 LTF, failure to pay the advance of costs after warning allows the court to refuse to enter into the appeal; the matter was therefore decided under the simplified procedure of Art. 108 para. 1 lit. a LTF.
