Questione giuridica chiave
Whether the appeal against administrative detention still had an object after the appellant left Switzerland.
Decisione estratta
The appeal had become moot because the appellant had left Switzerland; the court took note of this and struck the case from the docket.
Motivazione estratta
A request for immediate release no longer had any practical purpose once the detainee was no longer in Switzerland, so there was no live controversy to decide.
