Kernrechtsfrage
Whether the constitutional complaint was admissible despite non-payment of the court cost advance within the extended deadline.
Extrahierter Entscheid
No; the complaint could not be entered because the cost advance was not paid or duly proved within the non-extendable deadline.
Extrahierte Begründung
After the appellant was warned under Art. 62(3) BGG, he neither paid the advance in cash nor deposited it at a post office for the court, nor submitted the required payment confirmation for a transfer order. The court therefore had to refuse entry under the cited procedural provisions.
