Questione giuridica chiave
Whether the appeal had to be entered into despite non-payment of the advance on costs.
Decisione estratta
No. The appeal was inadmissible because the advance on costs was not paid within the time limit, including the extended deadline.
Motivazione estratta
The appellants failed to pay the required advance on costs by the deadline fixed under Art. 62(3) LTF; the appeal was therefore inadmissible under Art. 108(1)(a) LTF.
