Maluka v Maluka

The appeal in Maluka v Maluka concerns a dispute between the father and mother of a child over parenting arrangements. The case was heard in the Family Court of Australia, with an appeal subsequently made to the Full Court of the Family Court. The central legal issue in the appeal was whether the trial judge erred in considering certain social science material without providing the parties with an opportunity to comment on its admissibility and relevance. Specifically, the father argued that the judge did not adequately consider the material's relevance and the potential for unfair prejudice, as required under section 144 of the Evidence Act.

The Full Court examined whether the trial judge properly adhered to the procedural requirements for taking judicial notice of facts, as outlined in section 144 of the Evidence Act. The Court referenced expert commentary on the use of social science material and the need for parties to be given an opportunity to comment on such material. The Court also noted that the Full Court in McCall v Clark had emphasised the importance of parties being informed when a judge intends to rely on material not presented by the parties. Given these principles, the Court found that the trial judge did not provide the parties with a sufficient opportunity to comment on the social science material, leading to a breach of natural justice.

Consequently, the appeal was allowed, and the orders made by the trial judge were set aside. The Court ordered that the matter be remitted for re-hearing before a different judge. Additionally, the Court granted costs certificates to both parties, allowing for potential reimbursement of their legal costs from the Attorney-General under the Federal Proceedings (Costs) Act 1981.
