They accused former immigration minister Chris Bowen of failing to legally designate Manus Island as an asylum seeker processing centre.
A statement issued by the court said the asylum seeker had entered Australia's migration zone by sea at Christmas Island in July last year as an "unauthorised maritime arrival", ensuring his transferral to the Manus Island centre.
