Question juridique clé
Whether the appeal must be entered into despite non-payment of the court advance within the deadline.
Solution extraite
No entry was possible because the appellant did not pay the required advance or prove timely payment as instructed.
Motifs extraits
After an unsuccessful request for legal aid, the appellant was given a non-extendable grace period under Art. 62(3) BGG with a non-entry warning. He neither paid in cash nor provided the required debit confirmation, so non-entry followed under Art. 108(1)(a) BGG.
