Question juridique clé
Whether the request for immediate release was admissible despite the cassatory nature of the public law appeal
Solution extraite
The request for release was admissible because annulment alone would not restore a constitutional situation; a positive order could be required if detention was unjustified.
Motifs extraits
An exception to the cassatory nature of the remedy applies where a concrete measure is necessary, especially when preventive detention is no longer justified.
