Kernrechtsfrage
Whether the complaint should be entered into despite non-payment of the requested court advance
Extrahierter Entscheid
No. The advance was neither paid nor duly evidenced within the supplementary deadline, so the complaint had to be dismissed without entry.
Extrahierte Begründung
Under Art. 62(3) BGG, failure to pay the advance after a grace period leads to non-entry pursuant to Art. 108(1)(a) BGG.
