Kernrechtsfrage
Whether the appeal could be entered into despite non-payment of the court cost advance
Extrahierter Entscheid
No. Because the appellants failed to pay the ordered cost advance even within the additional deadline, the appeal could not be examined.
Extrahierte Begründung
Under Art. 62(3) BGG, failure to pay the required advance after a warning and grace period leads to non-entry; the simplified procedure under Art. 108(1)(a) BGG applies.
