Kernrechtsfrage
Whether the appeal had to be entered into despite non-payment of the cost advance.
Extrahierter Entscheid
Because the appellant did not pay the required advance even within the extended deadline, the court had to decline to hear the appeal.
Extrahierte Begründung
Under Art. 62 BGG, failure to pay the ordered cost advance within the set time limit leads to non-entry in simplified procedure under Art. 108(1)(a) BGG.
