Questione giuridica chiave
Whether the appeal had to be declared inadmissible because the appellant failed to pay the advance on costs within the additional deadline.
Decisione estratta
Yes. The advance was not paid within the validly set additional deadline, so the appeal was inadmissible under Art. 101(3) CPC.
Motivazione estratta
After a first non-payment, the court granted a non-extendable additional five-day deadline and warned of inadmissibility. The appellant did not pay, and service by postal fiction was valid.
