Kernrechtsfrage
Whether the appeal had to be dismissed as inadmissible for non-payment of the required advance of costs.
Extrahierter Entscheid
Yes. Because the advance of costs was not paid within the deadlines granted, the appeal was declared inadmissible under the simplified procedure.
Extrahierte Begründung
The court noted that two successive deadlines were set, with an express warning of inadmissibility. As the appellant still failed to pay, Article 62(3) LTF required inadmissibility, decided under Article 108(1)(a) LTF.
