Question juridique clé
Whether the appeal must be entered into despite non-payment of the advance on costs after a final deadline.
Solution extraite
No. Because the appellant did not pay the advance or prove timely payment, the appeal was not entered into.
Motifs extraits
After refusal of legal aid for lack of prospects, the court set a non-extendable final deadline under Art. 62(3) BGG. The appellant neither paid in cash nor provided the required debit confirmation within the deadline, so non-entry followed under Art. 108(1)(a) BGG.
