Question juridique clé
Whether the civil appeal could be entered into despite non-payment of the required advance on costs.
Solution extraite
No. Because the advance on costs was not paid within the prescribed time, the appeal had to be declared inadmissible.
Motifs extraits
The appellant did not pay or credit the advance within the extended deadline; under the Federal Tribunal Act, failure to pay the advance leads to inadmissibility, with costs borne by the appellant.
