Question juridique clé
Whether the cantonal court acted arbitrarily by departing from the expert opinion that supported a work-education measure
Solution extraite
No. The court could depart from the expert opinion because it reasonably questioned the factual premises underlying the prognosis and gave cogent reasons based on prison reports and lack of therapeutic motivation.
Motifs extraits
An expert opinion is not binding; departure is permissible when the court identifies reliable facts or indications that seriously undermine its force. Here the expert relied heavily on the appellant's own statements and on assumptions contradicted by disciplinary reports, conflict incidents, and the failed training attempt.
