Kernrechtsfrage
Whether the appeal can be entered into despite non-payment of the court advance within the extended deadline.
Extrahierter Entscheid
No. Because the advance was not paid even within the additional deadline, the appeal had to be dismissed without entering into the merits under the Federal Supreme Court Act.
Extrahierte Begründung
Under Art. 62(3) BGG, failure to pay the advance after warning permits non-entry in simplified proceedings under Art. 108(1)(a) BGG.
