Questão jurídica principal
Whether the appeal remained admissible despite expiry of the challenged deportation detention order
Decisão extraída
The current legal interest had lapsed because the detention order expired on 2009-05-04; no exceptional reason justified deciding the merits.
Fundamentação extraída
The appellant was either released or a new detention-extension decision existed, in which case a fresh challenge was possible; therefore the matter had become moot.
