Mannall v State of New South Wales

The appellant, Ms Mannall, brought proceedings against the respondent, the State of New South Wales, alleging she had suffered psychological injury as a result of stress experienced in her employment. The matter was heard by the Court of Appeal of New South Wales.

The central legal issue before the Court of Appeal was whether the primary judge had erred in finding that the appellant had failed to establish a claim for negligence against the respondent. This involved a determination of whether the respondent owed a duty of care to the appellant in relation to her psychological well-being at work, and if so, whether that duty had been breached, causing the appellant's injury.

The Court of Appeal found that the primary judge had made an error in their assessment of the evidence and the application of the relevant legal principles concerning negligence and psychological injury in the workplace. While the case did not present any novel or unsettled questions of legal principle, the Court determined that a new trial was necessary to properly address the appellant's claim.

Consequently, the Court of Appeal allowed the appeal, ordered that the respondent pay the appellant's costs of the appeal, and remitted the matter for a new trial.
