Kernrechtsfrage
Whether the federal appeal must be entered into despite non-payment of the required advance costs within the extended deadline.
Extrahierter Entscheid
No. Because the advance payment was not made even within the additional time limit, the court could not enter into the appeal in simplified procedure.
Extrahierte Begründung
Under Art. 62 para. 3 BGG, failure to pay the advance costs after a reminder and grace period justifies non-entry under Art. 108 para. 1 lit. a and para. 2 BGG.
