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 within the additional time limit.
Extrahierte Begründung
Under Art. 62 para. 1 and 3 LTF, failure to pay the requested advance after a supplementary deadline makes the appeal inadmissible; the court therefore declined to enter into the merits under Art. 108 para. 1 let. a LTF.
