Question juridique clé
Whether the appeal was admissible despite non-payment of the advance on costs.
Solution extraite
No. Because the advance on costs was not paid within the supplementary deadline, the appeal could not be examined on the merits and had to be declared inadmissible.
Motifs extraits
Under Art. 62(3) LTF, failure to pay the advance on costs within the set time limit results in inadmissibility. The court therefore used the simplified procedure under Art. 108(1)(a) LTF.
