Kernrechtsfrage
Whether the Federal Supreme Court could enter into the appeal despite non-payment of the required cost advance within the set grace period.
Extrahierter Entscheid
No. Because the appellant failed to pay the advance even within the extended deadline, the appeal could not be heard.
Extrahierte Begründung
Under Art. 62(3) BGG, non-payment of the requested advance after expiry of the grace period permits non-entry; the case was decided in simplified procedure under Art. 108(1)(a) BGG.
