Kernrechtsfrage
Whether the appeal was admissible despite non-payment of the court cost advance.
Extrahierter Entscheid
The appeal was inadmissible because the required advance was not paid within the time limit.
Extrahierte Begründung
After two payment deadlines, the court confirmed that no advance had been paid or credited, nor had any proof of debit been received; under the Federal Supreme Court Act, the appeal had to be declared inadmissible.
