The High Court has dismissed an appeal against a decision of the Full Federal Court of Australia regarding the principles governing the causal link required for the imposition and calculation of an account of profits where profits were made by a knowing participant in a dishonest and fraudulent breach of fiduciary duty, and has allowed a cross-appeal by a majority, holding that there was no reason to restrict the profits recoverable to five years. Consequently a knowing assistant of a dishonest and fraudulent breach of fiduciary duty was required to disgorge the total capital value of the business it acquired by reason of the breach.
