Kernrechtsfrage
Whether the constitutional complaint had to be entered into despite non-payment of the required cost advance and missing proof of timely payment.
Extrahierter Entscheid
No. Because the appellant neither paid the advance in cash nor proved timely debiting after the grace period, the Court could not enter into the complaint.
Extrahierte Begründung
After a prior warning under Art. 62(3) BGG, non-payment of the cost advance within the non-extendable deadline triggered non-entry under Art. 117 in conjunction with Art. 108(1)(a) BGG.
