Questão jurídica principal
Whether the appeal was admissible despite the expiry of the detention order and lack of current practical interest.
Decisão extraída
No admissible current practical interest was shown; the appeal was inadmissible to that extent.
Fundamentação extraída
For detention-review complaints, a current practical interest is required. The appellant did not show such an interest or why it should be dispensed with, and any later detention would require a new, separately challengeable order.
