Kernrechtsfrage
Whether the appeal could be entered into despite the appellant's failure to pay the court advance within the final deadline.
Extrahierter Entscheid
No. Because the advance payment was not made and no proof of timely debit was provided, the Court could not enter into the appeal.
Extrahierte Begründung
After an unsuccessful request to designate a Swiss service address and after a final non-extendable deadline under Art. 62(3) BGG, the appellant neither paid the advance in cash nor at a post office counter, nor proved timely debit following a payment order. Non-entry was therefore mandatory.
