Western Australian Government Holdings Ltd & Ors v Southern Equities Corporation Ltd & Ors; The State of Western Australia v Southern Equities Corporation Ltd & Ors (P24-93

The proceedings before the High Court of Australia involved the Western Australian Government Holdings Ltd, the State of Western Australia, and the State Energy Commission of Western Australia, as applicants, against Southern Equities Corporation Ltd and others, as respondents. The core of the dispute concerned the discoverability of certain documents, with the applicants seeking to resist discovery on grounds of privilege.

The legal issues before the Court revolved around the principles governing the discovery of documents, particularly in the context of litigation. Specifically, the Court was required to consider whether certain documents, including those generated during the course of litigation or for the dominant purpose of litigation, were subject to discovery. This involved an examination of existing authorities and the application of the "sole purpose test" established in *Grant v Downs*, as contrasted with the "substantial purpose test" favoured in some English authorities.

The applicants' submissions, as presented by Mr. Heenan, sought to distinguish several Full Court authorities that were adverse to their position. They argued that cases such as *Handley v Baddock* ought not be followed, and that other cases like *Anderson v Bank of British Columbia* and *Kennedy v Lyell* did not directly address the discoverability of documents prepared for litigation. The applicants also referred to *North Australian Territory Company v Goldsborough Mort* and *H.W. Strachan*, arguing that these decisions were either distinguishable on their facts, based on discretionary grounds, or involved dicta that did not represent a definitive statement on privilege. The Court was also invited to consider the decision in *Waugh v British Railways Board*, which adopted a substantial purpose test, and to analyse the difficulties in extracting a coherent principle from the existing case law on discovery.
