Key legal question
Whether the complaint could be entered into despite non-payment of the advance on costs.
Extracted holding
No. Because the advance on costs was not paid within the time limit and additional period, the court would not consider the complaint under Art. 108 BGG.
Extracted reasoning
The appellant had been warned that failure to pay the CHF 2,000 advance by 2013-01-16 would lead to non-entry. As payment was not made, the complaint had to be dismissed at the admissibility stage.
