Kernrechtsfrage
Whether the appeal could be entered into despite non-payment of the advance on costs.
Extrahierter Entscheid
No. Because the advance on costs was not paid even within the extended deadline, the Court did not enter into the appeal in summary proceedings.
Extrahierte Begründung
Under Art. 62(1) and (3) BGG, the appellant must pay the expected costs in advance; if the advance is not paid within the extended deadline, the Federal Supreme Court may not enter into the filing.
