Question juridique clé
Whether the appeal had to be dismissed for failure to pay the required court advance within the extended deadline.
Solution extraite
The appeal was not admitted because the appellant did not pay the advance even within the statutory grace period.
Motifs extraits
Under Art. 62(3) BGG, failure to pay the requested advance within the extended period leads to non-entry; the case was therefore handled in simplified procedure under Art. 108(1)(a) and (2) BGG.
