Question juridique clé
Whether the cantonal court violated the right to be heard by refusing to hear witness A. at the appellate hearing.
Solution extraite
No constitutional violation occurred because the accused had already been able to question the witness during the earlier confrontation procedure, and no strict immediacy principle applied in the cantonal appeal proceedings.
Motifs extraits
The right to question an incriminating witness is satisfied if exercised once during the proceedings; the constitution does not require examination again at the appellate hearing.
