Kernrechtsfrage
Whether the appeal had to be declared inadmissible for failure to pay the required advance of costs within the additional deadline.
Extrahierter Entscheid
Yes. Because the appellant did not pay the advance within the granted additional period, the appeal was inadmissible.
Extrahierte Begründung
Under Art. 62(3) LTF, non-payment of the advance within the time limit leads to inadmissibility; the court applied the simplified procedure under Art. 108(1)(a) and (2) LTF.
