Kernrechtsfrage
Whether the constitutional complaint can be entered into despite non-payment of the court-ordered advance costs within the non-extendable grace period.
Extrahierter Entscheid
No. Because the appellant failed to pay the advance costs or provide proof of timely payment, the court could not enter into the complaint.
Extrahierte Begründung
After a warning under Art. 62(3) BGG, non-compliance with the non-extendable grace period triggers non-entry under Art. 117 BGG in conjunction with Art. 108(1)(a) BGG.
