Question juridique clé
Whether the accusation-principle challenge was admissible and well founded.
Solution extraite
The challenge was inadmissible because it had not been raised before the cantonal court; in any event, the indictment sufficiently identified the place, date, and conduct.
Motifs extraits
New constitutional arguments are barred absent prior cantonal exhaustion; no serious hearing violation arose because the indictment described the core conduct and the appellant could respond on appeal.
