93 In the first category of legal proceedings, it will be necessary to identify and apply the legal principles which govern the duty (if any) of the particular trustee to provide 'trust documents' or information to any of the beneficiaries or possible beneficiaries. Two different approaches are discernible from the case law in relation to the right (if any) of a beneficiary to inspect 'trust documents' or receive information. See Rouse [88]. One approach is based on the observations of Lord Wrenbury in O'Rourke, 626, as explained by Gummow J in Re Simersall, 588 and by Dawson and Toohey JJ in Breen, 89. See [72] - [75] above. The other approach is based on a trustee's fiduciary duty to keep the beneficiaries informed and to render accounts. See Hartigan Nominees, 421 - 422 (Kirby P, dissenting), 438 - 447 (Sheller JA). Traditionally, there has been a distinction between strict trusts on the one hand and discretionary trusts on the other in relation to access to 'trust documents' or information. In Schmidt, however, the Privy Council held that a beneficiary's right to inspect 'trust documents' or receive information in the possession of the trustee was merely a procedural right for the court to make an order in its discretion as part of its supervisory jurisdiction in relation to trusts. The decision in Schmidt was followed by Gzell J in Avanes. However, in McDonald and in Schaverien v Jones [2007] NSWSC 1429, Bryson AJ declined to follow Schmidt and Avanes. See, generally, Jacobs' Law of Trusts in Australia (7th ed, 2006) [1716]. The current state of the non-statutory law on this issue is attended by some uncertainty. It is unnecessary, in the present case, to express an opinion on these issues (including whether the approach of the Privy Council in Schmidt represents the law of Australia) because the pending Supreme Court proceedings by Mrs Murray against the appellant are not proceedings where the cause of action is based on the appellant's alleged breach of duty in failing to provide Mrs Murray with access to 'trust documents' or information. I note, for completeness, the intervention of statute in Western Australia. By s 94 of the Trustees Act 1962 (WA), the court can call on trustees to substantiate and uphold their conduct.
