Kernrechtsfrage
Whether the appeal was admissible despite non-payment of the advance of costs.
Extrahierter Entscheid
No. The appeal was inadmissible because the required advance of costs was not paid within the time limit, including the additional deadline.
Extrahierte Begründung
After the order setting an advance of CHF 500 and the extension under Art. 62(3) LTF, the appellants still failed to pay in time; under Art. 108(1)(a) LTF the appeal had to be declared inadmissible.
