Question juridique clé
Whether the constitutional complaint against the cantonal detention decision was admissible in part.
Solution extraite
The complaint was admissible as to the challenge to detention and the request for immediate release, but new arguments not raised below were inadmissible.
Motifs extraits
The Federal Court applied the exhaustion rule and the novum prohibition to reject the newly raised objection based on an allegedly non-independent investigating judge; a request for release from detention is however generally permissible in a constitutional complaint.
