Kernrechtsfrage
Whether the constitutional complaint had to be admitted despite non-payment of the court advance.
Extrahierter Entscheid
No. Because the appellant did not pay the advance within the non-extendable grace period and did not provide proof of timely payment, the complaint had to be dismissed as inadmissible.
Extrahierte Begründung
Under Art. 62(3) BGG, failure to pay the required advance after warning leads to non-entry under Art. 108(1)(a) BGG.
