Question juridique clé
Whether the complaint against the detention remained admissible despite the appellant's release and deportation.
Solution extraite
The complaint had lost its practical interest because the detention had ended and no exception to the current-interest requirement applied.
Motifs extraits
Under Art. 89(1)(c) BGG, a current and practical interest must exist until judgment. Once detention ends, review of the detention normally becomes moot; no exceptional reason justified entering the case.
