Question juridique clé
Whether the appeal against the September 6, 2007 detention decision had become moot after the later September 18, 2007 decision
Solution extraite
Yes. The appellant was no longer detained under the challenged decision but under the later decision, so the appeal had become moot.
Motifs extraits
Because the factual and legal basis of detention had changed, the appeal directed exclusively against the earlier decision no longer had practical significance and had to be struck from the roll under the procedural rules on mootness.
