Kernrechtsfrage
Whether the appeal had to be admitted despite non-payment of the advance of costs.
Extrahierter Entscheid
No. Because the advance of costs was not paid in time, the appeal was inadmissible.
Extrahierte Begründung
The appellant did not comply with the advance-of-costs order and the additional non-extendable deadline; under the Federal Supreme Court Act this entails inadmissibility.
