Key legal question
Whether the appeal had to be entered into despite non-payment of the ordered advance costs.
Extracted holding
The court did not enter into the appeal because the advance costs were not paid within the extended deadline.
Extracted reasoning
The appellant was warned under Art. 62 BGG, granted a grace period, and expressly notified that failure to pay would lead to non-entry. As payment was still not made, non-entry followed under Art. 108 BGG.
