Minister for Immigration & Multicultural & Indigenous Affairs v Al Masri  FCAFC 70 at 87

Australia is holding more than 30 people in indefinite detention for undisclosed reasons. These people are recognised refugees who cannot return home due to the dangers they face there. But Australia will not release them from detention due to secret claims made against them by Australia's spy agency ASIO. They have not been told the grounds for their continued detention and so cannot challenge the accusations against them.

This cannot be allowed to continue. The UN says they should be released.
