Kernrechtsfrage
Whether the appeal had to be entered into despite non-payment of the advance on costs.
Extrahierter Entscheid
No. As the advance of costs was not paid within the prescribed time, the appeal was inadmissible.
Extrahierte Begründung
The appellant did not pay the CHF 2,000 advance within the deadline, nor did he provide proof of debit; under the Federal Supreme Court Act this requires non-entry.
