Question juridique clé
Whether the detention extension was justified by collusion risk under cantonal and constitutional law.
Solution extraite
No. Given the advanced state of the investigation and the limited remaining need to confront the applicant with evidence, continued detention was no longer justified by concrete collusion risk.
Motifs extraits
The court accepted that some collusion had likely occurred earlier, but most relevant evidence was already secured. Further detention could only serve a few remaining investigative steps and not a prolonged deprivation of liberty. The risk linked to the planned French house search was minor, and the mother’s detention also heavily burdened the children.
