Kernrechtsfrage
Whether the appeal had to be entered into despite non-payment of the advance on costs
Extrahierter Entscheid
No. The advance was not paid and no proof of debit was produced, so the appeal was inadmissible.
Extrahierte Begründung
The deadline for paying the advance was expressly non-extendable, the amount was fixed according to constant practice, and the appellant did not comply with Art. 48(4) LTF.
