Whether the appeal had to be dismissed for non-payment of the required advance on costs.
Yes. Because the appellant did not pay the advance within the time limit, the appeal was inadmissible.
Under Art. 69(1bis) LAI and Art. 47(2)-(3) LPA-VD, social insurance appeals against benefit decisions are subject to court costs and the authority may require an advance; failure to pay within the deadline makes the appeal inadmissible.
