Kernrechtsfrage
Whether the complaint against deportation custody remained justiciable after the appellant's removal from Switzerland.
Extrahierter Entscheid
The complaint had become moot because the custody ended with the appellant's departure; no reasons justified a merits review despite mootness.
Extrahierte Begründung
The detention contested in the complaint ended with the appellant's departure, so the current legal interest in review fell away. The restrictive conditions for nevertheless deciding the merits were not met.
