Kernrechtsfrage
Whether the appeal should be entered into despite non-payment of the cost advance within the extended deadline.
Extrahierter Entscheid
No. Because the cost advance was not paid even within the additional deadline, the appeal could not be considered.
Extrahierte Begründung
Under Art. 62(3) BGG and Art. 108(1)(a) BGG, failure to pay the required advance after the grace period leads to non-entry.
