Kernrechtsfrage
Whether the federal appeal had to be entered into despite non-payment of the court cost advance within the deadline and grace period.
Extrahierter Entscheid
No. Because the advance payment was not made even within the extended deadline, the appeal could not be considered.
Extrahierte Begründung
Under Art. 62(3) BGG, failure to pay the required advance within the set period, including the grace period, results in non-entry.
