Kernrechtsfrage
Whether the Federal Supreme Court could hear the appeal despite non-payment of the ordered cost advance.
Extrahierter Entscheid
The appeal could not be heard; the court declined to enter into the matter because the advance was not paid within the extended deadline.
Extrahierte Begründung
Under Art. 62(3) BGG, failure to pay the ordered advance after a grace period permits non-entry; the case was decided in simplified procedure under Art. 108(1)(a) BGG.
