Key legal question
Whether the appeal could be entered into despite non-payment of the court advance.
Extracted holding
No. Because the advance payment was not made even within the extended deadline, the court could not enter into the appeal.
Extracted reasoning
Under Art. 62 para. 1 and 3 BGG, the appellant must pay an advance for expected court costs; if the advance is not paid within the set time, the legal remedy is not heard after warning.
