Question juridique clé
Whether the appeal could be considered despite non-payment of the court advance within the extended time limit.
Solution extraite
No. Because the advance was not paid within the additional deadline, the court had to decline to enter into the appeal in simplified proceedings.
Motifs extraits
Under Art. 62(3) BGG, failure to pay the advance after a grace period permits non-entry under Art. 108(1)(a) BGG.
