Kernrechtsfrage
Whether the appeal could be entered into despite non-payment of the ordered advance costs within the final deadline.
Extrahierter Entscheid
No. Because the appellant did not pay the advance costs even within the extended deadline, the appeal had to be declared inadmissible.
Extrahierte Begründung
Under Art. 62(3) BGG, failure to pay the required advance within the set time limit allows non-entry; the case was therefore handled in simplified procedure under Art. 108(1)(a) and (2) BGG.
