Kernrechtsfrage
Whether the appeal could proceed despite non-payment of the court advance within the extended time limit.
Extrahierter Entscheid
No; the appeal had to be dismissed as inadmissible because the advance payment was not made within the extended deadline.
Extrahierte Begründung
Under Art. 62(3) BGG, failure to pay the required advance within the grace period leads to non-entry in simplified proceedings under Art. 108(1)(a) BGG.
