Question juridique clé
Whether the federal criminal appeal was sufficiently reasoned when it challenged only one of two independent cantonal grounds.
Solution extraite
The appeal was inadmissible because the appellant did not address the cantonal court's main ground of untimeliness.
Motifs extraits
When an appealed decision rests on several independent and sufficient grounds, the appellant must show that each is unlawful; failing to challenge the principal ground of inadmissibility renders the federal appeal insufficiently reasoned under Art. 42 para. 2 LTF.
