Question juridique clé
Whether the appeal could be entertained despite non-payment of the cost advance within the extended time limit.
Solution extraite
No. Because the advance was not paid even after the grace period, the appeal had to be dismissed by non-entry.
Motifs extraits
Under Art. 62(3) BGG, failure to pay the required advance within the set period allows the court to refuse to hear the appeal. The request for free legal aid was already rejected because the appeal lacked sufficient prospects of success, so the later plea of indigence did not change the result.
