Question juridique clé
Whether the federal appeal had to be entered into despite non-payment of the court advance within the extended deadline.
Solution extraite
No. Because the advance was not paid and proof of timely payment was not filed, the court had to refuse entry into the appeal.
Motifs extraits
The appellant ignored the final deadline under Art. 62(3) BGG, so non-entry followed under Art. 108(1)(a) BGG.
