Key legal question
Whether the complaint had to be entered into despite non-payment of the court advance.
Extracted holding
No entry could be made because the required advance was not paid within the set deadline, including the grace period.
Extracted reasoning
The appellant received the payment order, did not react, was granted a statutory grace period with a warning of non-entry, and still failed to pay; therefore the appeal was inadmissible under Art. 108 BGG.
