Question juridique clé
Whether the appeal could be entered into despite non-payment of the ordered cost advance.
Solution extraite
No. Because the ordered cost advance was not paid within the deadline, the appeal could not be considered.
Motifs extraits
The court had warned that failure to pay the advance would lead to non-entry; since payment was not made on time, the appeal had to be dismissed procedurally under Art. 108 BGG.
