Haines Bros Earthmoving Pty Ltd v Rosecell Pty Ltd

Haines Bros Earthmoving Pty Ltd (appellants) appealed to the Court of Appeal of New South Wales against a decision of the primary judge concerning claims of conversion brought by Rosecell Pty Ltd and another company (respondents). The dispute arose from the unauthorised sale of the respondents' goods, which had been sold to the appellants by a third party. This third party had allegedly deprived the controllers of the respondent companies of control over their affairs and assets through physical duress.

The Court of Appeal was required to determine whether the respondents were entitled to succeed in their claims for conversion against the appellants, who were bona fide purchasers for value without notice. A key issue was whether the respondents were estopped from asserting their ownership rights due to their alleged omission to make their claim known or discoverable to the appellants. This involved considering whether the respondents had a duty to notify authorities of the duress and deprivation of control, whether their silence constituted conduct sufficient to give rise to an estoppel by omission, and whether the appellants had relied on this conduct. The court also had to consider the relevance of common law estoppel principles in interpreting section 26(1) of the *Sale of Goods Act 1923* (NSW) and the necessity for equivalence of knowledge regarding the factual circumstances surrounding the transaction.

The Court of Appeal ultimately dismissed the appeal. The reasoning of the court, as articulated by Beazley P, Sackville AJA, and Barrett AJA, focused on the application of section 26(1) of the *Sale of Goods Act 1923* (NSW) and the principles of estoppel. The court found that the respondents had not breached any duty that would give rise to an estoppel by omission, nor had the appellants established the necessary elements of reliance. The circumstances of the duress and deprivation of control meant that the respondents were not precluded from asserting their ownership rights against the appellants, even as bona fide purchasers.

The appeal was dismissed with costs.
