Question juridique clé
Whether the appeal should be entered into despite non-payment of the advance of costs.
Solution extraite
No; the appeal had to be declared inadmissible because the advance of costs was not paid within the final deadline.
Motifs extraits
After the legal-aid request was rejected and a further deadline was granted with an express warning, the appellant still did not pay the advance of costs, triggering inadmissibility under the Federal Supreme Court Act.
