Kernrechtsfrage
Whether the appeal was admissible after the appellant failed to pay the requested advance of costs within the extended deadline.
Extrahierter Entscheid
The appeal was inadmissible because the appellant did not comply with the final deadline to pay the advance of costs.
Extrahierte Begründung
Under Art. 62(3) LTF, failure to pay the required advance within the set deadline leads to inadmissibility; the case was therefore disposed of in simplified procedure under Art. 108(1)(a) and (2) LTF.
