Questão jurídica principal
Whether the appeal against the extension of removal detention remained admissible after the complainant was transferred to serve a prison sentence.
Decisão extraída
The appeal became moot because the detention had to be lifted once the complainant was transferred to the prison authorities, so there was no current interest in review.
Fundamentação extraída
No special reasons justified deciding the case despite mootness; the strict conditions for doing so were not met.
