Question juridique clé
Whether the appeal had to be declared inadmissible because the cost advance was not paid within the extended deadline.
Solution extraite
Yes. Since the appellant did not pay the advance within the additional time limit, the appeal was declared inadmissible in summary procedure.
Motifs extraits
Under Art. 62(3) LTF, failure to pay the required advance after warning leads to inadmissibility; the case was therefore handled under Art. 108(1)(a) and (2) LTF.
