Crown immunity exempts road authority from liability for truck accident 12 December 2016 By NSW Compensation Lawyers A truck driver was unsuccessful in his claim for compensation against a local road authority when he was injured after a road collapsed and his truck rolled into a water course. This recent case illustrates the difficulty in successfully claiming compensation against road authorities.Crown immunity to liabilityIn NSW, the Civil Liability Act (2002) provides road authorities a broad protection from civil liability, including compensation claims for negligence. Section 43A applies to public authorities and s 45 applies to road authorities.To succeed in these cases under s 43A, the injured party will likely face difficulty. Firstly, they need to prove that the relevant act or omission that caused the injury was ‘so unreasonable that no authority having the functions of the authority in question could properly consider the act or omission to be a reasonable exercise of its functions’.And second, under s 45, the injured party needs to prove that at the time of the accident the road authority ‘had actual knowledge of the particular risk the materialisation of which resulted in the harm’.The circumstances surrounding the accidentOn 1 January 2010, Mr Mansfield was driving a tipper truck with a load of water along Green Cross Road, south of Stroud. As he travelled along the single lane road crossing a culvert, the bank on the left side of the road collapsed and his truck rolled into the water course below. Mr Mansfield suffered injuries from the accident and commenced a compensation claim against the local road authority, the Great Lakes Council.Court rules against truck driverBefore the District Court, Mr Mansfield claimed that he was injured due to the Council’s negligence in failing to build a big enough culvert. He claimed this could have prevented the erosion that led to the collapse of the embankment and caused his truck to roll.In response, the Council’s defence relied on the immunity from liability by ss 43A and 45 of the Civil Liability Act. In assessing the particulars of the case, the trial judge found that the driver had failed to establish that the Council was liable for the accident.The issues on appealOn appeal, there were three main issues at stake:Whether the failure to carry out road works at the crash site was ‘so unreasonable’ that no roads authority could properly consider the omission to be a reasonable failure to exercise its statutory powersWhether the Council was immune from liability for the failure to carry out road works given that Council officers didn’t know of the riskWhether proper road signage could have prevented the accident from happening.Court of Appeal finds the Council not liableThe Court of Appeal reviewed the case and found in favour of the Council. On the first point, the Court found that the evidence just didn’t satisfy the ‘so unreasonable’ requirement.On the second point, there was no evidence that any of the relevant officers in the Council had actual knowledge of the risk that caused the embankment to collapse.And on the third point, the Court of Appeal found that nothing was raised on appeal to show that a sign, warning of the narrowness of the culvert or a weight limit on the road, would have prevented the accident.Mansfield v Great Lakes Council [2016] NSWCA 204Motor Vehicle, Personal Injury
