Kernrechtsfrage
Whether the complaint had to be entered into after the advance on costs was not paid within the deadline.
Extrahierter Entscheid
The court did not enter into the complaint.
Extrahierte Begründung
Because the advance on costs was not paid even within the additional time limit, non-entry was mandatory under Art. 62(3) BGG in simplified proceedings under Art. 108(1)(a) BGG.
