“The liability is not to ensure a bowling green which is entirely free from all irregularities or changes in level at all. The question is whether a reasonable person would regard it as presenting a real source of danger. Obviously, in theory any irregularity, any hollow or any protrusion may cause danger, but that is not the standard that is required.” 8. If the Claimant succeeds in establishing the various elements of her claim under section 41 it will then be necessary to consider the Second Defendant’s reliance on the statutory defence. Section 58 of the 1980 Act provides, “(1) In an action against a highway authority in respect of damage resulting from their failure to maintain a highway maintainable at the public expense it is a defence (without prejudice to any other defence or the application of the law relating to contributory negligence) to prove that the authority had taken such care as in all the circumstances was reasonably required to secure that the part of the highway to which the action relates was not dangerous for traffic. (2) For the purposes of a defence under subsection (1) above, the court shall in particular have regard to the following matters: (a) the character of the highway, and the traffic which was reasonably to be expected to use it; (b) the standard of maintenance appropriate for a highway of that character and used by such traffic; (c) the state of repair in which a reasonable person would have expected to find the highway; (d) whether the highway authority knew or could reasonably have been expected to know that the condition of the part of the highway to which the action relates was likely to cause danger to users of the highway; (e) where the highway authority could not reasonably have been expected to repair that part of the highway before the cause of action arose, what warning notices of its condition had been displayed; but for the purposes of such a defence it is not relevant to prove that the highway authority had arranged for a competent person to carry out or supervise the maintenance of the part of the highway to which the action relates unless it is also proved that the authority had given him proper instructions with regard to the maintenance of the highway and that he had carried out the instructions.””
