MacMillan v Mumby & Anor

The appeal in *MacMillan v Mumby & Anor* concerned a dispute over a loan where no written agreement existed. The central issue was whether the monies advanced by the appellant, MacMillan, were intended to be a loan to a company or to the respondents, Mumby and another individual, personally. MacMillan alleged a mistake as to the identity of the borrowers, claiming the funds were paid to the company due to a misrepresentation by the respondents.

The court was required to determine whether MacMillan's mistake regarding the identity of the contracting parties was fundamental, thereby vitiating the agreement. Further, the court considered whether the respondents had made a negligent misrepresentation or breached a warranty concerning the identity of the borrowers. The appellant sought to recover the advanced monies on the basis of money had and received.

The Court of Appeal upheld the primary judge's findings, concluding that MacMillan had not established a fundamental mistake. The evidence indicated that MacMillan intended to lend money to the company, and any misapprehension about the company's financial standing or the respondents' personal liability did not negate this intention. The court found no basis for a claim of negligent misrepresentation or breach of warranty, as the respondents had not misrepresented the identity of the borrower.

Consequently, the appeal was dismissed with costs.
