Question juridique clé
Whether the cantonal court violated the presumption of innocence by relying on the confession despite later retractions.
Solution extraite
No violation: the cantonal court did not shift the burden of proof and its credibility assessment of the confession was not arbitrary.
Motifs extraits
The court reviewed the circumstances of the confession and the later retractions, found the confession voluntary, and gave reasons why the retractions were less credible; this assessment was not untenable.
