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 paid even within the grace period, the appeal had to be dismissed by non-entry in simplified proceedings.
Extracted reasoning
Under Art. 62(3) BGG, failure to pay the requested advance payment after the additional deadline allows non-entry; the court therefore applied Art. 108(1)(a) and (2) BGG.
