Kernrechtsfrage
Whether the appeal could be entered into despite non-payment of the advance costs within the extended deadline.
Extrahierter Entscheid
No. Because the appellant did not pay the advance costs even within the grace period, the court had to decline entering into the appeal in summary procedure.
Extrahierte Begründung
Under Art. 62(3) BGG, failure to pay the required advance costs after a time limit permits non-entry; the court applied the simplified procedure under Art. 108(1)(a) and (2) BGG.
