Kernrechtsfrage
Whether the federal appeal can be admitted despite non-payment of the cost advance within the extended deadline.
Extrahierter Entscheid
The appeal could not be entered into because the appellants failed to pay the required advance on costs even within the grace period.
Extrahierte Begründung
After denial of legal aid, the court ordered payment of the advance on costs and warned that non-payment would lead to non-entry; the appellants still did not pay.
