Kernrechtsfrage
Whether the appeal was admissible despite non-payment of the advance on costs
Extrahierter Entscheid
The appeal was inadmissible because the appellant failed to pay the required advance even after a supplementary deadline with warning of inadmissibility.
Extrahierte Begründung
Under Art. 62(1) LTF the party filing to the Federal Supreme Court must advance the presumed costs; under Art. 62(3) LTF, failure to pay within the supplementary period makes the appeal inadmissible. The appellant did not comply, so summary inadmissibility under Art. 108(1)(a) LTF was appropriate.
