Kernrechtsfrage
Whether the appeal had to be admitted despite non-payment of the court cost advance.
Extrahierter Entscheid
No. The Federal Supreme Court did not enter into the appeal because the required advance was not paid within the extended deadline.
Extrahierte Begründung
Under Art. 62 BGG, the appellant must pay an advance for estimated court costs. If the advance is not paid even after a grace period, the court may refuse to enter into the appeal under Art. 62(3) BGG and Art. 108 BGG.
