Kernrechtsfrage
Whether the appeal should be entered into despite non-payment of the required cost advance within the deadline.
Extrahierter Entscheid
The appeal could not be heard because the cost advance was not received by the court in time.
Extrahierte Begründung
The appellant was granted a deadline and statutory grace period to pay the advance, with a warning of non-entry. Since payment did not arrive by the expiry of the grace period, the appeal had to be dismissed at the threshold under Art. 108 BGG.
