The Supreme Court has denied a bid from two rapists to appeal in the court, saying no treatment could stop them from reoffending.
Allan Brian Miller and Michael John Carrol are serving preventive detention sentences after each committed multiple rapes.
At the Court of Appeal in 2010, Miller and Carrol claimed the Parole Board was not independent and that the Department of Corrections failed to provide them with rehabilitative treatments.
But the Supreme Court found that no treatment could stop them reoffending and even if the appeal against the Parole Board was successful, they still would not be eligible for parole.
The court decided there was no point in allowing the appeal to go ahead.
