Questione giuridica chiave
Whether the civil law appeal is admissible despite non-payment of the court advance within the extended deadline.
Decisione estratta
No. The Federal Supreme Court could not enter into the merits because the advance on costs was neither paid nor credited within the time limit.
Motivazione estratta
Under Art. 48(4) and Art. 62(3) LTF, failure to pay the requested advance after a warned supplementary deadline leads to inadmissibility; the case could be dealt with summarily under Art. 108(1)(a) LTF.
