Kernrechtsfrage
Whether the appeal should be entered into despite non-payment of the court advance within the extended deadline.
Extrahierter Entscheid
No. Because the advance was not paid within the grace period, the appeal had to be declared inadmissible in simplified procedure.
Extrahierte Begründung
Under Art. 62(3) BGG, failure to pay the required advance despite a final deadline permits non-entry under Art. 108(1)(a) and (2) BGG.
