Question juridique clé
Whether the appeal had to be declared inadmissible because the ordered advance costs were not paid in time.
Solution extraite
Yes. No payment was made by the deadline, and the appellant did not respond when invited to do so; the appeal was therefore inadmissible.
Motifs extraits
Under Art. 69 para. 1bis LAI and Art. 47 LPA-VD, failure to pay the requested advance costs within the set time limit entails inadmissibility when the party does not remedy the default after being prompted.
