Aristocrat Technologies Australia Pty Ltd & Ors v Global Gaming Supplies Pty Ltd & Ors ; Aristocrat Technologies Australia Pt Ltd & Ors v Allam & Ors

The High Court of Australia considered appeals arising from proceedings brought by Aristocrat Technologies Australia Pty Ltd and others (the appellants) against Global Gaming Supplies Pty Ltd and others, and against Allam and others (the respondents). The dispute concerned allegations of misleading and deceptive conduct and breaches of copyright in relation to electronic gaming machines. The appellants sought to restrain the respondents from dealing with certain gaming machines and associated software, alleging that these machines and software were copies or adaptations of Aristocrat's proprietary gaming machines and intellectual property.

The central legal issues before the High Court were whether the respondents had engaged in misleading or deceptive conduct in contravention of the *Trade Practices Act 1974* (Cth) (now the *Competition and Consumer Act 2010* (Cth)) and the *Australian Consumer Law*, and whether they had infringed Aristocrat's copyright in the software and other elements of its gaming machines. Specifically, the Court had to determine the scope of the alleged misleading conduct, including whether the respondents' actions conveyed a false impression about the origin or nature of the gaming machines, and the extent to which the respondents' machines reproduced substantial parts of the appellants' copyrighted works.

The High Court's reasoning focused on the application of the relevant statutory provisions to the facts as found by the lower courts. The Court analysed the elements of misleading or deceptive conduct, considering whether the respondents' conduct was likely to mislead or deceive a significant portion of the relevant public. In relation to copyright infringement, the Court examined whether the respondents had copied a substantial part of the appellants' original works, considering both quantitative and qualitative aspects of the alleged copying. The Court applied established principles of copyright law, including the requirement for originality and the test for substantiality.

The High Court allowed the appeals in part, finding that certain conduct of the respondents did constitute misleading or deceptive conduct and that there had been copyright infringement. The Court made declarations to this effect and remitted the proceedings to the Federal Court of Australia for further orders, including the assessment of damages and the determination of appropriate injunctive relief.
