Question juridique clé
Whether the appeal against continued preventive detention was admissible and whether the detention met legal requirements
Solution extraite
The appeal was admissible, but the detention remained lawful because sufficient suspicions and a serious risk of reoffending persisted.
Motifs extraits
The Court held that preventive detention requires a legal basis, public interest and proportionality; on judicial review, it checks these points freely except for arbitrariness in evidence assessment. The cantonal decision was within those limits.
