Kernrechtsfrage
Whether the appeal could be entered into after the appellant failed to pay the required advance on costs within the extended deadline.
Extrahierter Entscheid
No. Because the advance on costs was not paid even within the grace period, the court did not enter into the appeal.
Extrahierte Begründung
The appellant ignored the order requiring payment of a CHF 500 advance on costs by the extended deadline; under the cited BGG provisions, this justified non-entry in summary procedure.
