Question juridique clé
Whether the defendant's right to be heard was violated when security detention was ordered without prior hearing.
Solution extraite
The defendant should have been heard before security detention was ordered, but the violation was cured on appeal because the appellate court had full review powers, the defendant could make submissions, and no disadvantage resulted.
Motifs extraits
A hearing defect can exceptionally be remedied if the appellate court has full cognition, the party suffers no prejudice, and the violation is not particularly serious. Those conditions were met here.
