Kernrechtsfrage
Whether the appeal had to be entered into despite non-payment of the court advance within the non-extendable grace period.
Extrahierter Entscheid
No. Because the appellant neither paid the advance nor proved timely payment by debit confirmation, the Court could not proceed.
Extrahierte Begründung
After warning under Art. 62(3) BGG, failure to pay the advance or to provide the required confirmation triggered non-entry under Art. 108(1)(a) BGG.
