Cadd v Cadd

William Cadd (the plaintiff) brought an action against his brother, Henry Cadd (the defendant), in the Supreme Court of South Australia. The plaintiff sought a declaration that the defendant had purchased certain leasehold land as his agent and held it as a trustee for him. The plaintiff's case was based on oral testimony, and the trial judge found in his favour. The defendant appealed this decision to the High Court of Australia.

The central legal issue before the High Court was whether the oral evidence presented by the plaintiff established the relationship of principal and agent, thereby creating a trust over the land in favour of the plaintiff. Specifically, the court had to determine the legal effect of a conversation between the brothers where the defendant allegedly stated, "I'll buy the place for you." The court also considered whether this alleged oral agreement, if it existed, was sufficient to overcome the lack of written documentation and the Statute of Frauds.

The High Court, by majority, found that the evidence did not establish the required relationship of principal and agent. While acknowledging the trial judge's advantage in assessing witness credibility, the High Court considered the surrounding circumstances and documentary evidence. The court reasoned that the crucial oral statement, "I'll buy the place for you," was ambiguous and could be interpreted in several ways, including a promise to purchase the land for himself with a subsequent offer to sell it to the plaintiff on certain terms, rather than an immediate creation of an agency or trust. The existence of a subsequent "halves agreement" between the brothers, which documented the plaintiff as a cultivator and the defendant as the proprietor, was seen as strong documentary evidence contradicting the plaintiff's claim of agency and trust.

Consequently, the High Court reversed the decision of the Supreme Court. The appeal was allowed, and the plaintiff's action was dismissed. The defendant was granted possession of the land, with his counterclaim for mesne profits being waived.
