The family of slain Australian gangland killer Carl Williams will use the state ombudsman's damning report on his murder in their bid to sue the Victorian Government.
Lawyer Nicole Spicer said legal action had been in the pipeline for 18 months, but Wednesday's report by Ombudsman George Brouwer on Williams' death in a high-security wing of Barwon Prison had prompted a rethink of the case.
Central to Brouwer's criticisms was his claim Corrections Victoria failed in its statutory duty to ensure Williams' safety. Spicer said the ombudsman's remarks were "very reinforcing" to the case being brought by Williams' father George, his daughter Dhakota and step-daughter Breanane.
Williams was murdered inside his prison unit in April 2010 by fellow inmate Matthew Charles Johnson, who received a life term for the killing. Williams had been serving three life sentences for murders committed during Melbourne's gangland wars.
Brouwer questioned why prison authorities had left the two together despite several "warning signals" that Williams was in danger from Johnson.
