Rinehart & Anor v Hancock Prospecting Pty Ltd & Ors; Rinehart & Anor v Georgina Hope Rinehart & Ors

The parties to this proceeding were Gina Rinehart and her children, John Hancock and Bianca Rinehart (the "Rinehart children"), and Hancock Prospecting Pty Ltd and its directors (the "Hancock Prospecting defendants"). The dispute concerned the beneficial ownership of certain shares in Hancock Prospecting Pty Ltd, which were held on trust for the Rinehart children. The Rinehart children sought to enforce their beneficial interest in these shares, alleging that their mother, Gina Rinehart, had acted in breach of trust. The matter was heard by the High Court of Australia.

The High Court was required to determine whether the Rinehart children had established a claim for breach of trust against their mother and the Hancock Prospecting defendants, and if so, what relief was appropriate. Central to this was the interpretation of the trust deed and the nature of the alleged breaches, including whether Gina Rinehart had improperly dealt with the trust property or failed to account for it. The court also considered the principles governing the enforcement of express trusts and the remedies available for breach of trust.

The High Court ultimately found that the Rinehart children had not established their claim for breach of trust. The court analysed the terms of the trust deed and concluded that Gina Rinehart's actions, as described by the Rinehart children, did not constitute a breach of her fiduciary duties as trustee. The court applied established principles of trust law, emphasizing the importance of the express terms of the trust instrument and the need for clear evidence to establish a breach of trust. The court noted that the onus was on the beneficiaries to prove the alleged breaches.

The High Court dismissed the Rinehart children's appeal.
