Kernrechtsfrage
Whether the complaint is admissible despite non-payment of the cost advance by the deadline.
Extrahierter Entscheid
The Court could not enter into the complaint because the appellant did not pay the required cost advance despite the warned deadline.
Extrahierte Begründung
The advance and statutory grace period were set with a warning of non-entry; since the advance was not paid, non-entry follows under Art. 108 BGG.
