Muggleton v Tong

The appeal concerned an assessment of damages for professional negligence brought by the plaintiffs, Mr. and Mrs. Muggleton, against their former solicitors, Tong and Tong. The dispute arose from the solicitors' advice regarding a loan to a company, which ultimately led to the clients providing a mortgage over their home as security. The solicitors contended that their advice did not cause the clients to offer a mortgage rather than an unsecured guarantee. The matter was heard in the Court of Appeal of New South Wales.

The primary legal issue before the Court of Appeal was whether the assessment of damages made by the primary judge was correct, specifically in relation to the calculation of the loss suffered by the Muggletons due to the solicitors' alleged negligence. The court was required to determine if the solicitors' advice was causative of the loss, and if so, how that loss should be quantified, considering the alternative of an unsecured guarantee.

The Court of Appeal upheld the primary judge's assessment of damages. The court found that the solicitors' negligence had caused the Muggletons to provide a mortgage over their property, which represented a greater loss than if they had provided an unsecured guarantee. The reasoning focused on the difference in the security provided and the consequent financial detriment to the plaintiffs. The court applied principles of causation and the assessment of damages in professional negligence claims, confirming that the loss was correctly calculated based on the difference between the secured and unsecured positions.

The appeal was dismissed.
