Whether the appeal had to be entered into despite non-payment of the advance on costs
No. The appellant failed to pay the advance within the prescribed time and did not timely request an extension or legal aid; the appeal was therefore inadmissible.
Under Art. 69 al. 1bis LAI and Art. 47 LPA-VD, an advance on costs may be required and failure to pay within the deadline leads to non-entry. Financial difficulty alone does not excuse the omission; the party must request a deadline extension or legal aid before expiry.
