Kernrechtsfrage
Whether the appeal had to be admitted despite non-payment of the advance on costs
Extrahierter Entscheid
No. Because the appellant failed to pay the advance within the prescribed deadlines, the appeal had to be declared inadmissible.
Extrahierte Begründung
Under Art. 62(3) LTF, failure to pay the required advance after warning leads to inadmissibility; the simplified procedure of Art. 108(1)(a) and (2) LTF applies.
