Whether the appeal could be entered into despite non-payment of the ordered advance of costs
No. Because the appellant neither paid the advance of costs nor produced an assistance-legal-aid decision within the extended time limit, the appeal had to be declared inadmissible.
Under Art. 69(1bis) LAI and Art. 47(2)-(3) LPA-VD, an advance of costs is required in AI benefit disputes, and failure to pay after warning leads to non-entry.
