Question juridique clé
Whether the public law appeal was admissible despite an available nullity appeal raising the sentence-computation complaint.
Solution extraite
The complaint concerned federal law on sentencing and therefore had to be brought by nullity appeal, not by public law appeal.
Motifs extraits
Under Art. 84(2) OJ, public law appeal is subsidiary. A challenge to the extent of the sentence reduction invokes Art. 63 CP and is a matter of federal law reviewable through nullity appeal under Art. 269 PPF.
