Question juridique clé
Whether the criminal appeal was admissible despite non-payment of the required advance on costs.
Solution extraite
The appeal was inadmissible because the advance on costs was not paid within the non-extendable additional deadline.
Motifs extraits
Under Art. 62(1) and (3) LTF, failure to pay the required advance within the additional period after an initial default makes the appeal inadmissible; the request for a second extension could not cure the default.
