The State Government is seeking legal advice to determine if other WA prisoners jailed indefinitely could be affected by a High Court ruling which freed a man last week after nearly 27 years.
Gregory John Yates won a High Court appeal which quashed an indefinite detention order imposed in 1987 under section 662 of the Criminal Code.
He spent almost 20 years in jail after finishing a six-year and three-month term for sexually assaulting a young girl in a shopping centre toilet.
Section 662 has been repealed and indefinite detention is now dealt with under different provisions in the Sentencing Act.
But the Department of Corrective Services has confirmed another eight prisoners are held indefinitely under section 662 orders.
They have served between 14 and 27 years, including their original fixed terms.
Attorney-General Michael Mischin said legal advice was expected soon on the implications from the Yates judgment.
He did not have an application for compensation from Mr Yates and said any such request would be considered on its merits.
