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