Kernrechtsfrage
Whether the appeal had to be dismissed for failure to pay the court advance within the extended deadline.
Extrahierter Entscheid
The appeal was not admitted because the advance was still unpaid after the grace period.
Extrahierte Begründung
Under Art. 62(3) BGG and the simplified procedure of Art. 108(1)(a) BGG, non-payment of the required advance justified non-entry.
