Kernrechtsfrage
Whether the constitutional complaint could be entered into despite non-payment of the court cost advance within the set deadline.
Extrahierter Entscheid
No entry could be made because the appellant neither paid the advance nor proved timely debit/payment as required after the final deadline.
Extrahierte Begründung
After proper warning under Art. 62(3) BGG, the advance was still not paid or duly evidenced within the non-extendable grace period; under Art. 117 BGG in connection with Art. 108(1)(a) BGG, this required non-entry.
