Kernrechtsfrage
Whether the appeal against the 9 December 2008 detention extension remained live.
Extrahierter Entscheid
The legal interest had lapsed because that order was replaced by the later detention decision of 8 January 2009.
Extrahierte Begründung
The appellant remained detained, but solely on the basis of the newer order; the same objections could be fully examined in the second federal case, so the first case became moot.
