Questione giuridica chiave
Whether the Federal appeal was admissible despite non-payment of the required advance on costs within the extended deadline.
Decisione estratta
No. Because the appellant did not pay the advance within the additional non-extendable period, the appeal had to be declared inadmissible.
Motivazione estratta
Under Art. 62 LTF, failure to pay the advance within the second deadline leads to inadmissibility; the defect was manifest, so simplified procedure applied.
