Kernrechtsfrage
Whether the appeal had to be declared inadmissible because the required advance on costs was not paid within the extended deadline.
Extrahierter Entscheid
Yes. The appellant did not pay the advance on costs even after being granted an additional deadline, so the appeal was inadmissible.
Extrahierte Begründung
Under Art. 62 para. 1 and 3 LTF, the party bringing the case must advance the expected costs; if the required amount is not paid within the additional deadline after a first failure, the appeal is inadmissible. The court therefore rejected the manifestly inadmissible appeal under Art. 108 para. 1 let. a LTF.
