Since the early nineties Justice Mullighan, a Supreme Court of South Australia Senior Judge, has been actively promoting cultural awareness amongst the judiciary and magistracy in South Australia and supporting innovation in the sentencing of Aboriginal defendants. He has chaired the cultural awareness committee of the court since 1995. This committee has managed seminars, and community justice workshops through which cultural awareness within the judiciary is promoted.
In 1997, he instigated a Law and Justice Conference which was hosted by the traditional communities of the Anangu Pitantjatjara Yankunyjatara (APY) Lands, bringing together Aboriginal law men and a group of judges and magistrates. He has advocated for Aboriginal court interpreters and has promoted models of restorative and community justice.
Justice Mullighan has been active in nominating Aboriginal Justices of the Peace and has examined traditional Aboriginal ways of dealing with offending behaviours. He has championed Aboriginal Reconciliation among his peers and within the general South Australian community.
