Question juridique clé
Whether the appeal must be entered into despite non-payment of the court costs advance after an extended deadline.
Solution extraite
No. Because the advance payment was not made even within the grace period, the appeal could not be considered.
Motifs extraits
Under Art. 62(3) BGG, failure to pay the ordered advance costs after the additional deadline authorizes non-entry. The case was therefore disposed of in simplified procedure under Art. 108(1)(a) BGG.
