Kernrechtsfrage
Whether the appeal had to be declared inadmissible because the court advance was not paid within the prescribed time.
Extrahierter Entscheid
Yes. The appellant failed to pay the required advance of costs within the extended deadline and did not timely prove that the amount had been debited, so the appeal was inadmissible.
Extrahierte Begründung
Under Art. 62 para. 3 sentence 3 LTF, non-payment of the advance after a final deadline leads to inadmissibility; the defect was manifest, allowing summary handling under Art. 108 para. 1 let. a LTF.
