MacGIBBON v Warner; MacGIBBON v Ventura; MacGIBBON v O'Connor

The New South Wales Court of Appeal considered appeals by the MacGibbons (the appellants) against decisions of the primary judge in three separate proceedings brought against Warner and others, Ventura and others, and O'Connor and others (the respondents). The dispute concerned the appellants' entitlement to a commission on the sale of certain properties. The primary judge had found that the appellants were not entitled to the commission, and the appeals sought to overturn these findings.

The central legal issues before the Court of Appeal were whether the primary judge had erred in finding that the appellants had not procured the sale of the properties in question, and whether the respondents were estopped from denying the appellants' entitlement to commission. Specifically, the Court had to determine if the conditions precedent to the appellants' entitlement to commission, as stipulated in the respective agency agreements, had been met.

The Court of Appeal dismissed the appeals, upholding the primary judge's findings. It reasoned that the evidence did not establish that the appellants had procured the sale of the properties within the terms of the agency agreements. The agreements required the appellants to introduce a purchaser who ultimately completed the purchase, and the Court found that this causal link was not demonstrated. The Court also rejected the argument that the respondents were estopped from denying the commission, finding no basis for such an equitable claim in the circumstances. The legal principle applied was that a party seeking commission under an agency agreement must prove they have fulfilled the contractual conditions entitling them to that commission.

The appeals were dismissed, and the orders of the primary judge were affirmed.
