Kernrechtsfrage
Whether the federal appeal could be entered into despite non-payment of the requested advance costs.
Extrahierter Entscheid
No; the appeal could not be examined because the advance costs were neither paid nor credited within the additional time limit.
Extrahierte Begründung
Under Art. 48(4) and Art. 62(3) LTF, failure to pay the advance costs within the extended deadline makes the appeal inadmissible.
