The mother of an autistic and intellectually disabled man who has spent half his life locked away, is appealing to the Supreme Court to set him free.
The man lives in seclusion at the Mason Clinic, after committing a minor offence in 2004.
Lawyers fighting for his release say his detention is arbitrary, unjust and breaches his human rights.
The Crown says his detention is justified because of the very high risk he poses to the public.
Investigative reporter Anusha Bradley has been looking into this case.
Bradley spoke to Ingrid Hipkiss.
