Two convicted paedophiles lost a High Court appeal in Australia against the laws that have made possible their indefinite detention, media reports said.
Edward Pollentine, 55, and Errol Radan, 75, were each convicted of a series of child sex offences by a Queensland court in 1984.
The men were sentenced under state laws that date back to 1945 and makes it possible for a court to order a sex offender to prison for an indefinite period if a psychiatric assessment finds the person incapable of controlling their sexual instincts.
The men launched a High Court challenge last last year, arguing that the laws were incompatible with an independent and impartial court system, according to the report.
The court dismissed the case and said it was up to the court to impose such a sentence, and safeguards such as judicial review were in place, ABC reported.
The Queensland government is seeking to toughen legislation on sex offences. - Sapa-dpa
