Question juridique clé
Whether the appeal is admissible despite non-payment of the requested advance on costs.
Solution extraite
No. In invalidity insurance appeal proceedings, the cantonal appeal procedure is not free of charge and failure to pay the ordered advance within the deadline, without explanation, renders the appeal inadmissible.
