Kernrechtsfrage
Whether the appeal was admissible despite non-payment of the additional advance on costs
Extrahierter Entscheid
The appeal was inadmissible because the appellant did not pay the advance of costs within the additional deadline.
Extrahierte Begründung
Under Art. 62(3) LTF, failure to pay the required advance after warning allows the appeal to be declared inadmissible; the Court used the simplified procedure of Art. 108(1)(a) LTF.
