Kernrechtsfrage
Whether the appeal could be entered into despite non-payment of the advance costs.
Extrahierter Entscheid
No. Because the appellant did not pay the advance costs or prove timely payment by account debit, the appeal had to be dismissed by non-entry.
Extrahierte Begründung
The advance costs were demanded under threat of non-entry, a final non-extendable deadline ran, and the appellant neither paid in cash nor at a post office nor provided the required debit confirmation. Under Art. 62(3) BGG and Art. 108(1)(a) BGG, non-entry followed.
