Kernrechtsfrage
Whether the appeal had to be dismissed for non-payment of the advance on costs within the extended deadline.
Extrahierter Entscheid
The court did not enter into the appeal because the advance on costs was not paid in time.
Extrahierte Begründung
Under Art. 62(3) BGG, failure to pay the advance even after an additional deadline leads to non-entry in simplified proceedings under Art. 108(1)(a) BGG.
