Kernrechtsfrage
Whether the appeal had to be entered into despite non-payment of the advance on costs.
Extrahierter Entscheid
No. Because the appellant neither paid the advance nor used the additional deadline, the Court declined to enter into the appeal.
Extrahierte Begründung
Under Art. 62 BGG, an advance on costs is required; if it is not paid within the additional deadline, the Federal Supreme Court may not enter into the filing.
