Question juridique clé
Whether the appeal is admissible despite non-payment of the required advance on costs.
Solution extraite
The appeal is inadmissible because the appellant did not pay the requested advance even after being granted an additional deadline with an explicit warning.
Motifs extraits
Under Art. 62 LTF, the party filing the appeal must advance the expected costs; if the advance is not paid within the additional deadline after an initial non-payment, the appeal is inadmissible. The court therefore refused to enter into the merits under Art. 108(1)(a) LTF.
