Kernrechtsfrage
Whether the appeal could be entered into despite non-payment of the court advance within the non-extendable deadline.
Extrahierter Entscheid
No. Because the appellant did not pay the advance or prove timely debit/payment, the Court had to refuse to enter into the appeal.
Extrahierte Begründung
After warning under Art. 62(3) BGG and setting a final deadline, the appellant neither paid in cash nor via post office/bank and also failed to submit the required debit confirmation. Under Art. 108(1)(a) BGG, non-entry followed.
