Questione giuridica chiave
Whether the appeal is admissible despite non-payment of the required advance of costs.
Decisione estratta
The appeal is inadmissible because the required advance of costs was not paid within the time limits set, including the extended deadline.
Motivazione estratta
Under Art. 62 para. 3 LTF, failure to pay the requested advance within the prescribed period leads to inadmissibility; the Federal Court therefore did not enter into the merits.
