Kernrechtsfrage
Whether the Federal Supreme Court could enter into the complaint despite the unpaid court advance.
Extrahierter Entscheid
No. Because the appellant neither paid the advance nor proved timely payment by bank/post debit confirmation within the final deadline, the complaint was inadmissible.
Extrahierte Begründung
The reminder under Art. 62(3) BGG expressly warned of non-entry. Failure to comply with the advance-payment order required non-entry under Art. 108(1)(a) BGG.
