Kernrechtsfrage
Whether the appeal had to be declared inadmissible because the advance on court costs was not paid within the prescribed time limit.
Extrahierter Entscheid
Yes. Since the advance was neither paid nor credited in time, the appeal was inadmissible.
Extrahierte Begründung
Under the Federal Supreme Court Act, failure to pay the advance within the fixed or extended deadline requires a finding of inadmissibility.
