Questão jurídica principal
Whether the appeal against the 3 December 2010 detention decision had become moot after the 15 December 2010 security-detention order
Decisão extraída
The earlier proceeding became moot because the detention basis was replaced by the later order.
Fundamentação extraída
The current detention rested on the 15 December 2010 order, so the challenge to the earlier order no longer had practical effect.
