Questione giuridica chiave
Whether the appeal could be entered into despite the unpaid advance of costs.
Decisione estratta
No. Because the appellant failed to pay the advance even within the extended time limit, the court could not examine the appeal.
Motivazione estratta
Under Art. 62(3) BGG, failure to pay the required advance after a final deadline leads to non-entry; the simplified procedure under Art. 108(1)(a) and (2) BGG applies.
