Kernrechtsfrage
Whether the appeal had to be entered into despite non-payment of the required cost advance.
Extrahierter Entscheid
The appeal could not be entered into because the cost advance was not paid within the extended deadline.
Extrahierte Begründung
Under Art. 62(3) BGG, failure to pay the advance after warning and grace period permits non-entry in simplified proceedings under Art. 108(1)(a) BGG.
