Kernrechtsfrage
Whether the appeal was admissible despite the lack of a current practical interest.
Extrahierter Entscheid
The appellant no longer had a current interest in the review of the challenged detention decision, or a new detention-extension decision had to be challenged anew.
Extrahierte Begründung
The challenged decision only confirmed detention until 16 April 2011; by the time of the federal appeal, the appellant had either been released or a new extension decision existed. In either case, there was no current interest at filing, and no special grounds justified dispensing with that requirement.
