Question juridique clé
Whether the federal appeal was admissible despite non-payment of the required advance on costs.
Solution extraite
No. Because the requested advance on costs was not paid within the time limits granted, the appeal was inadmissible.
Motifs extraits
The court had set an initial deadline and then an additional deadline under Art. 62(3) LTF. As the advance still was not paid, the appeal had to be declared inadmissible under Art. 108(1)(a) LTF.
