Gander v Murray

This case involved a dispute between Murray, the purchaser, and Gander and Zobel, the vendors, concerning a contract for the sale of a mining property. Gander, who held an authority to enter and prospect on 20 acres of land under the Mining on Private Lands Acts, believed he had Zobel's authority to sell the partnership's entire interest in the mining venture. However, he lacked the actual authority to sell Zobel's share. Murray entered into an agreement with Gander to purchase the mining machinery, effects, and ore on the land, as well as the partners' interests. The matter came before the Supreme Court of New South Wales, which found in favour of Murray, declaring Zobel a trustee for Murray of a moiety of the benefits attaching to a subsequently acquired authority to enter. Gander appealed this decision.

The central legal issues before the court were whether the contract for sale could be enforced against Gander's subsequently acquired interest in a new mining adventure, and whether Zobel held that interest as a trustee for Murray. Specifically, the court had to determine if an equitable estoppel arose from Gander's initial contract, binding his future interests, and if the new authority to enter, obtained by Zobel and in which Gander later became a partner, was an accretion to or substitution for the original undertaking. The court also considered whether the contract, as an assignment of a partnership share, was enforceable against Zobel under the Partnership Act.

The High Court of Australia, allowing the appeal, held that Zobel acquired his authority to enter the land free of any equities in favour of Murray. The court reasoned that Gander's original authority to enter had expired, creating a complete break in title between the initial undertaking and the new adventure. Consequently, there was no equitable estoppel that could attach Gander's subsequently acquired interest to the original contract. Furthermore, even if Gander's new interest were considered an accretion, it was substantially different from what he had contracted to sell, meaning Murray was not entitled to equitable enforcement. The court also found that the contract operated as an assignment of a partnership share, which, by virtue of section 31 of the Partnership Act 1892, could not be enforced against Zobel, the other partner.

The appeal was allowed, and the decision of the Supreme Court of New South Wales was reversed. Murray's suit was dismissed, and the declaration that Zobel was a trustee for Murray was set aside.
