Kernrechtsfrage
Whether the appeal could be entered into despite non-payment of the required cost advance within the grace period.
Extrahierter Entscheid
No entry could be made because the appellant failed to pay the advance on costs within the additional deadline.
Extrahierte Begründung
Under Art. 62(3) BGG, failure to pay the ordered advance within the set grace period justifies non-entry under the simplified procedure of Art. 108(1)(a) BGG.
