Kernrechtsfrage
Whether the constitutional complaint could be entered into despite non-payment of the court-cost advance within the set deadline.
Extrahierter Entscheid
No. Because the advance was neither paid in cash nor properly evidenced as paid by bank/postal debit within the deadline, the complaint could not be entered into.
Extrahierte Begründung
Under Art. 62(3) BGG, failure to pay the required advance after a non-extendable grace period leads to non-entry; the warning had been given and the procedural requirements were not met.
