Kernrechtsfrage
Whether the appeal could be entered into despite non-payment of the court cost advance within the extended time limit.
Extrahierter Entscheid
No. Because the advance was not paid by the extended deadline, the court did not enter into the appeal.
Extrahierte Begründung
The appellant had been expressly warned that failure to pay the advance by 2007-05-07 would lead to non-entry. Since payment still did not occur, the procedural precondition for appellate review was not met.
