Hungerfords (Registered Firm) & Ors v Walker

The parties to this High Court of Australia proceeding were the appellants, Hungerfords (a registered firm) and associated firms, who were the auditors and accountants for the respondents, the Walker family partners. The dispute concerned alleged negligence by the appellants in preparing the partners' income tax returns, leading to overpayments of tax over approximately six years. While tax overpaid in the most recent three years was recoverable from the Commissioner, the respondents sought damages from the appellants for the tax overpaid in the preceding three years, amounting to approximately $47,000.

The central legal issues before the High Court were whether the appellants were negligent in their preparation of the income tax returns, and if so, what damages were recoverable. Specifically, the court had to determine the appropriate measure of damages, particularly in relation to the respondents' claim for compound interest on the overpaid tax. This claim was based on the argument that the partnership, which paid the individual partners' tax, had less available funds due to the overpayments, and these funds would otherwise have been used to reduce a high-interest debt owed to an outside financier, Mutual Acceptance.

The High Court considered the principles of causation and remoteness in assessing damages. The trial judge had rejected the claim for compound interest, finding that it was not proven that all the overpaid tax would have been retained by the partnership or applied to reduce the debt to Mutual Acceptance. The High Court affirmed that for damages to be recoverable, they must be caused by the breach of duty and not be too remote. The court examined the nature of the partners' loan accounts with the partnership and the partnership's financial arrangements, ultimately concluding that the respondents had not established a sufficient causal link between the negligent overpayment of tax and the alleged loss of opportunity to reduce the high-interest debt. The court applied the principles that a plaintiff must prove their loss and that the loss claimed must be a foreseeable consequence of the defendant's breach.
