Kernrechtsfrage
Whether the appeal is admissible despite non-payment of the advance on costs within the extended deadline.
Extrahierter Entscheid
The appeal is inadmissible because the appellant did not pay the advance on costs within the additional time limit.
Extrahierte Begründung
After warning the appellant that failure to pay would lead to inadmissibility, the deadline expired without payment; the appeal had to be rejected under the simplified procedure.
