Whether the appeal had to be declared inadmissible because the requested advance on costs was not paid in time.
Yes. The appellant failed to pay the advance, gave no explanation, and did not request restitution of the deadline or legal aid in time; the appeal was therefore inadmissible.
Under Art. 69 al. 1bis LAI and Arts. 47(2)-(3) LPA-VD, advance costs may be required in disability insurance appeals, and non-payment after warning leads to non-entry into the merits.
