Kernrechtsfrage
Whether the constitutional complaint could proceed despite non-payment of the required court advance within the final deadline.
Extrahierter Entscheid
No; the complaint could not be entered because the appellant neither paid the advance in cash nor proved timely debit after a payment order.
Extrahierte Begründung
After a warning under Art. 62(3) BGG and expiry of the non-extendable grace period, the required advance payment and proof of debit were still missing, so non-entry followed as threatened.
