Kernrechtsfrage
Whether the appeal should be entered into despite non-payment of the advance of costs.
Extrahierter Entscheid
No. Because the appellant did not pay the advance of costs within the final deadline, the appeal was inadmissible.
Extrahierte Begründung
Under Art. 62(3) LTF, failure to pay the requested advance after a non-extendable additional deadline leads to inadmissibility; the simplified procedure of Art. 108(1)(a) LTF applies.
