Kernrechtsfrage
Whether the criminal complaint had to be entered into despite failure to pay the cost advance.
Extrahierter Entscheid
No. After the advance was not paid within the extended deadline, the Federal Supreme Court did not enter into the complaint under Art. 108 BGG.
Extrahierte Begründung
The advance payment order had been duly served; the later reminder and warning were deemed served under Art. 44(2) BGG after being returned unclaimed. Because the deadline expired unused, non-entry was mandatory.
