Question juridique clé
Whether the criminal complaint appeal should be entered into despite non-payment of the required advance costs.
Solution extraite
No. Because the advance costs were not paid within the set deadlines, the appeal had to be dismissed without entering into the merits under Article 108 BGG.
Motifs extraits
The appellant was granted an initial deadline and a statutory grace period under Article 62(3) BGG, both with a warning that non-payment would lead to non-entry. Since payment was not made, non-entry followed as announced.
