Kernrechtsfrage
Whether the appeal had to be entered into despite non-payment of the court costs advance within the deadline.
Extrahierter Entscheid
No. Because the appellant failed to pay the advance costs or prove timely payment as required, the Court could not enter into the appeal.
Extrahierte Begründung
After a warning under Art. 62(3) BGG and expiry of the non-extendable grace period, the advance costs were neither paid in cash nor validly credited via post or bank, and no proof of timely debit was filed. Non-entry followed under Art. 108(1)(a) BGG.
