Key legal question
Whether the appeal could be entered into despite non-payment of the court advance within the extended deadline.
Extracted holding
No. Because the advance payment was not made even by the expiry of the additional deadline, the court had to refuse entry into the appeal in simplified proceedings.
Extracted reasoning
Under Art. 62 BGG, the party must pay the advance on estimated costs; if it is not paid within the extended period, the court does not enter on the filing.
