Whether the appeal had to be entered into despite non-payment of the ordered advance of costs
No. Because the required advance of costs was not paid within the set deadline, and no timely extension or justified impediment was shown, the appeal was inadmissible.
Under Art. 69 para. 1bis LAI and Art. 47 paras. 2-4 LPA-VD, the court may require an advance of costs and must warn that failure to pay leads to non-entry. The appellant admitted non-payment, did not request an extension, did not show excusing circumstances, and did not seek legal aid before the deadline.
