Questão jurídica principal
Whether the appeal should still be examined on the merits after the appellant's release from immigration detention.
Decisão extraída
The appeal had become moot because the current interest in judicial review had fallen away, and the strict conditions for deciding it anyway were not met.
Fundamentação extraída
After the appellant's release, the subject matter and current legal interest disappeared; the exceptional grounds for nevertheless deciding the case substantively were absent.
