Pilmer v Duke Group, Duke Group v Pilmer

The High Court of Australia considered appeals and cross-appeals arising from proceedings concerning the acquisition of the Duke Group by Pilmer. The primary dispute involved claims of misleading and deceptive conduct under the *Trade Practices Act 1974* (Cth) and the common law, brought by shareholders of Duke Group against Pilmer. Shareholders alleged that misleading financial information was provided during the takeover bid, leading them to accept an inadequate offer for their shares.

The central legal issues before the High Court were whether Pilmer had engaged in misleading or deceptive conduct in relation to the financial position of Duke Group, and if so, what damages were recoverable by the shareholders. Specifically, the court had to determine the appropriate measure of damages for loss caused by misleading representations in the context of a takeover bid, and whether the shareholders' reliance on the representations was causative of their loss.

The High Court, in a joint judgment, found that Pilmer had engaged in misleading and deceptive conduct. The court applied the principles of causation and remoteness in assessing damages. It held that the measure of damages should place the misled party in the position they would have been in had the misleading conduct not occurred. This involved considering what a reasonable investor would have done had they been in possession of accurate information, and the market value of the shares at the relevant time. The court affirmed that the loss suffered by the shareholders was the difference between the price they received for their shares and the price they would have received had the misleading conduct not occurred, taking into account the true value of the company.
