Question juridique clé
Whether the appellant's right to be heard was violated before placement in reinforced security regime.
Solution extraite
No violation was established; he was informed of the intended measure and could react, and an urgent prison-security context justified a limited procedure.
Motifs extraits
The factual findings showed that the deputy director personally informed the detainee of the intended decision. In prison-security matters, the hearing right may be restricted by urgency and institutional needs, and the appellant failed to show improper exercise of discretion.
