Kernrechtsfrage
Whether the nullity appeal had to be declared inadmissible because the ordered advance on costs was not paid within the deadline.
Extrahierter Entscheid
Yes. Because the advance was not paid by the set deadline, the appellant's submissions were inadmissible.
Extrahierte Begründung
Under former procedural law, the Federal Supreme Court could require security for expected costs; if it was not provided in time, the party's conclusions became inadmissible. No payment was received after the warning.
