Question juridique clé
Whether the civil appeal was admissible despite non-payment of the court costs advance within the deadline.
Solution extraite
The appeal was inadmissible because the advance on costs was not paid within the time limit, even after an extension.
Motifs extraits
Under Art. 62 para. 3 LTF, failure to pay the required advance within the granted period leads to inadmissibility; costs follow the appellants under Art. 66 paras. 1 and 5 LTF.
