Question juridique clé
Whether the appeal had to be declared inadmissible for non-payment of the required advance of costs within the second deadline.
Solution extraite
Yes. The late request for installment payment amounted to a request to extend a non-extendable deadline, and no basis existed to waive the advance or accept partial payment.
Motifs extraits
Under Art. 62 LTF, failure to pay the advance within the second deadline makes the appeal inadmissible. The appellant had sufficient time after notice of the refusal of legal aid to arrange payment, and no special reasons justified waiver.
