Kernrechtsfrage
Whether the appeal against the approval of deportation detention remained admissible after the appellant's deportation to Austria.
Extrahierter Entscheid
The appeal became moot because the deportation had already been carried out, so no live legal interest remained.
Extrahierte Begründung
Once the removal was executed, the purpose of the detention review disappeared; the case had to be declared closed and struck from the docket.
