Questione giuridica chiave
Whether the federal appeal is admissible despite non-payment of the advance on costs after the grace period.
Decisione estratta
No. Because the appellant neither paid the advance nor proved timely payment by debit confirmation, the Court must not enter into the appeal.
Motivazione estratta
After the request and non-extendable grace period under Art. 62(3) BGG, failure to comply triggers non-entry under Art. 108(1)(a) BGG.
