Kernrechtsfrage
Whether the federal appeal could be entered into despite non-payment of the required advance on costs.
Extrahierter Entscheid
The court could not enter into the appeal because the advance on costs was not paid within the set time limit.
Extrahierte Begründung
After an initial and a supplementary deadline, the court registry confirmed that the CHF 500 advance had neither been paid nor credited, so the appeal was manifestly inadmissible under the Federal Supreme Court Act.
