Questione giuridica chiave
Whether the federal appeal was admissible despite the appellant's failure to pay the advance of costs within the prescribed time limit.
Decisione estratta
The appeal was inadmissible because the advance of costs was not paid in time.
Motivazione estratta
Under Art. 62(3) LTF, failure to pay the required advance within the set period leads to inadmissibility; the court therefore could not examine the merits.
