Royal v Smurthwaite

The appeal concerned a collision at a highway intersection designed by the Roads and Traffic Authority (RTA). The primary dispute involved the apportionment of liability between the RTA, as the designer of the intersection, and one of the drivers involved in the collision, who was found to be negligent. The court was the Court of Appeal of New South Wales.

The central legal issues before the Court of Appeal were whether the trial judge had erred in finding the RTA liable for the defective design of the intersection, and whether the apportionment of contributory negligence between the drivers was appropriate. The court also had to consider the consequential orders regarding the costs of the trial and the appeal.

The Court of Appeal upheld the trial judge's finding that the RTA was liable for the defective design of the intersection, which contributed to the accident. The court found no reason to interfere with the trial judge's assessment of the primary driver's negligence and the contributory negligence of the other driver. The court's reasoning affirmed the principle that a road authority can be held liable for the negligent design of a highway intersection, particularly when that design contributes to accidents, even in circumstances where another driver is also found to be negligent.

The appeal was dismissed, with the court varying the costs order made by the trial judge. The defendant was ordered to pay the plaintiff's costs of the trial, excluding the plaintiff's costs against the RTA. The defendant was also ordered to pay the RTA's costs of the trial, encompassing costs incurred against the plaintiff and in relation to the defendant's cross-claim. The appellant was ordered to pay the costs of the first and second respondents for the appeal.
