Question juridique clé
Whether the criminal appeal was admissible despite non-payment of the court cost advance.
Solution extraite
The appeal was inadmissible because the advance payment deadline expired without payment.
Motifs extraits
After an additional deadline under Art. 62(3) LTF, accompanied by the warning of inadmissibility, the Federal Court received no payment; Art. 108(1)(a) LTF therefore required non-entry.
