Question juridique clé
Whether the public-law appeal could also seek immediate release despite the cassatory nature of the remedy.
Solution extraite
Yes; when admitting the appeal alone would not restore a constitutional situation, a positive order is permissible, including release from preventive detention.
Motifs extraits
Preventive detention is an exception to the ordinary cassatory effect because only a positive order can restore the lawful situation if detention is unjustified.
