Les Powell Electrical Contracting Pty Ltd v Powell

Les Powell Electrical Contracting Pty Ltd (the appellant) appealed to the New South Wales Court of Appeal against a decision of the Supreme Court of New South Wales. The dispute concerned the appellant's entitlement to recover certain payments made to the respondent, Mr. Powell, who was a former employee. The appellant sought to recover these payments on the basis that they were made under a mistake of fact.

The primary legal issue before the Court of Appeal was whether the appellant had established that the payments were made under a mistake of fact such that it was entitled to recover them from the respondent. This involved considering the nature of the mistake alleged and whether it was of a kind that would found a claim for money had and received.

The Court of Appeal held that the appellant had failed to establish that the payments were made under a mistake of fact. The evidence did not demonstrate that the appellant believed it was under a legal obligation to make the payments when it was not, or that it was mistaken about the existence of any facts that would justify the payments. The Court applied the principle that recovery of money paid under a mistake of fact requires proof that the payer was under a mistaken belief as to the existence of facts which, if true, would render the payment legally justifiable, or that the payer was under a mistaken belief that it was legally bound to make the payment when it was not. As this proof was lacking, the appeal was dismissed.
