Question juridique clé
Whether the federal criminal appeal was admissible despite non-payment of the required advance on costs.
Solution extraite
No. Because the appellant did not pay the requested advance even within the extended time limit, the appeal had to be declared inadmissible.
Motifs extraits
Under Art. 62 para. 1 and 3 LTF, failure to pay the advance after a supplementary deadline makes the appeal inadmissible; the appeal was therefore not entered into under Art. 108 para. 1 let. a LTF.
