Key legal question
Whether the appeal against the detention order was still admissible after the appellant's release
Extracted holding
The appeal had become moot because the appellant had been released.
Extracted reasoning
Since the appellant's release removed the subject of the challenge, there was no longer a live dispute. The court noted that an exception requiring review of the detention's lawfulness was not triggered because no violation of Arts. 5 or 8 ECHR was invoked.
