Whether the appeal could be entered into despite non-payment of the ordered advance of costs.
No; the appeal had to be declared inadmissible because the appellant did not pay the advance within the set deadline and did not react to the further invitation.
Under Art. 69 al. 1bis LAI and Art. 47 al. 2-3 LPA-VD, the procedure is subject to court costs and the appellant must advance them. The court warned that failure to pay would lead to non-entry. As no payment or response was received, the court could not entertain the appeal.
