Kernrechtsfrage
Whether the subsidiary constitutional complaint could be entered into despite non-payment of the required court advance within the non-extendable deadline
Extrahierter Entscheid
No. Because the advance was neither paid in cash nor duly credited with proof of timely payment, the complaint was not entered into.
Extrahierte Begründung
The complainant had been warned under Art. 62(3) BGG that failure to comply would lead to non-entry. The deadline expired without valid payment or the required bank/post confirmation, so non-entry followed under Art. 117 BGG in conjunction with Art. 108(1)(a) BGG.
