Question juridique clé
Whether the appeal court relied arbitrarily on the credibility expert report to uphold guilt
Solution extraite
The challenged report was not decisive for the conviction; the lower courts mainly relied on other evidence, so the complaint failed.
Motifs extraits
The Federal Court held that the cantonal courts did not base guilt primarily on the disputed expert report and therefore any attack on its probative value was merely directed at the reasoning, not the result.
