Kernrechtsfrage
Whether the appeal had to be declared inadmissible because the ordered advance of costs was not paid on time.
Extrahierter Entscheid
Yes. Since the advance of costs was not paid within the deadline, the appeal was inadmissible.
Extrahierte Begründung
The court noted that the deadline fixed in its interim order expired without payment; under the cited procedural provisions, this required non-entry.
