Commissioner for Main Roads v Franks

The Commissioner for Main Roads (the appellant) appealed to the New South Wales Court of Appeal against a decision of the District Court of New South Wales, which had awarded damages to Mr. Franks (the respondent) for injuries sustained in a motor vehicle accident. The dispute concerned the appellant's liability for the accident, which occurred when the respondent's vehicle collided with a concrete barrier erected by the appellant on the side of a road.

The Court of Appeal was required to determine whether the Commissioner owed a duty of care to road users in relation to the design and construction of the concrete barrier, and if so, whether that duty had been breached. Specifically, the court considered whether the barrier was negligently designed or constructed, and whether its presence constituted a hazard that the Commissioner ought to have foreseen and mitigated. The appeal also raised questions about the assessment of damages, including whether the respondent had failed to mitigate his loss.

The Court of Appeal found that the Commissioner owed a duty of care to road users to ensure that roads and associated structures, such as the concrete barrier, were designed and constructed with reasonable care. The court held that the barrier, as constructed, was a dangerous obstruction and that the Commissioner had been negligent in its placement and design, failing to take reasonable precautions to prevent foreseeable accidents. The court also found that the respondent had not failed to mitigate his loss.

The appeal was dismissed, and the decision of the District Court was affirmed.
