Question juridique clé
Whether the lower commission correctly declared the appeal inadmissible for non-payment of the ordered advance of costs.
Solution extraite
Yes. The commission was entitled to require an advance of costs, and no timely payment was shown.
Motifs extraits
The dispute did not concern insurance benefits, so the commission could demand an advance of costs under pain of inadmissibility. The documents produced related to a different earlier dispute and did not prove payment in this case.
