Kernrechtsfrage
Whether the constitutional complaint should be entered into despite failure to pay the court advance in time.
Extrahierter Entscheid
The court refused to enter into the complaint because the advance was neither paid in cash nor properly credited within the deadline, and no timely proof of payment was filed.
Extrahierte Begründung
After a warning under Art. 62(3) BGG and a non-extendable grace period, the appellant did not satisfy the advance-payment obligation; under Art. 117 BGG in conjunction with Art. 108(1)(a) BGG, non-entry followed.
