Kernrechtsfrage
Whether the Federal Supreme Court could enter into the complaint despite non-payment of the ordered cost advance within the grace period.
Extrahierter Entscheid
No. Because the advance payment was not made within the additional deadline, the complaint could not be heard.
Extrahierte Begründung
Under Art. 62(3) BGG and in the procedure of Art. 108(1)(a) BGG, failure to pay the required advance after expiry of the grace period results in non-entry.
