F. Content and breach of the duty of care
[150] The duty which arises under the common law of Australia may now be considered. Authorities having statutory powers of the nature of those conferred by the [Local Government Act] upon the present respondents to design or construct roads, or carry out works or repairs upon them, are obliged to take reasonable care that their exercise of or failure to exercise those powers does not create a foreseeable risk of harm to a class of persons (road users) which includes the plaintiff. Where the state of a roadway, whether from design, construction, works or non-repair, poses a risk to that class of persons, then, to discharge its duty of care, an authority with power to remedy the risk is obliged to take reasonable steps by the exercise of its powers within a reasonable time to address the risk. If the risk be unknown to the authority or latent and only discoverable by inspection, then to discharge its duty of care an authority having power to inspect is obliged to take reasonable steps to ascertain the existence of latent dangers wh ich might reasonably be suspected to exist.
[151] The perception of the response by the authority calls for, to adapt the statement by Mason J in Wyong Shire Council v. Shirt , a consideration of various matters; in particular, the magnitude of the risk and the degree of probability that it will occur, the expense, difficulty and inconvenience to the authority in taking the steps described above to alleviate the danger, and any other competing or conflicting responsibility or commitments of the authority. The duty does not extend to ensuring the safety of road users in all circumstances [The result, in broad terms, may not differ from the recommendation as to the obligations of local government bodies by the Public Bodies Review Committee of the New South Wales Parliament in its report, Public Liability Issues Facing Local Councils , November 2000, Recommendation 9 at 10:]. In the application of principle, much thus will turn upon the facts and circumstances disclosed by the evidence in each particular case.
[152] In dealing with particular cases and in determining factual issues respecting breach of duty, it may be convenient to differentiate between the design and construction of a roadway, between subsequent works done on it and between courses of inspection to ascertain its soundness. These matters are not mutually exclusive and sometimes may overlap.
54 In Webb v. The State of South Australia [1982] 56 ALJR 912, in a passage set out in Brodie at p539-540 [54], Mason, Brennan and Deane JJ analysed the duty of the highway authority in that case with respect to the risk presented by an artificial construction in terms of the analysis described in Wyong Shire Council v. Shirt (1980) 146 CLR 40 at 47-48 by Mason J; allocation of the alleged negligence as misfeasance or mere nonfeasance was not treated as significant.
55 In Brodie, when dealing with breach of duty in relation to repair and maintenance Gaudron, McHugh and Gummow JJ said: (at 579-580)
[158] A rejection of the "immunity" for "highway authorities" and the recognition of a duty of care in terms expressed above with reference to Wyong Shire Council v. Shirt does not necessarily involve the imposition of an obligation in all cases to exercise powers to repair roads or to ensure they are kept in repair. An authority may have various statutory powers invested in it and would be under a duty not to use, misuse or fail to use those powers to create a situation of danger which creates a reasonably foreseeable risk of injury to a user of the road.
[159] The discharge of the duty involves the taking by the authority of reasonable steps to prevent there remaining a source of risk which gives rise to a foreseeable risk of harm. Such a risk of harm may arise from a failure to repair a road or its surface, from the creation of conditions during or as a result of repairs or works [ Greater Bendigo City Council v Miles (2000) 31 MVR 137 at 137-138.], from a failure to remove unsafe items in or near a road [An issue adverted to by Hayne J in Romeo v Conservation Commission (NT) (1998) 192 CLR 431 at 488 [153]. See, eg, Stovin v Wise [1996] AC 923; cf Weir v Commissioner for Main Roads (1947) 17 LGR 1; Vale v Whiddon (1949) 50 SR (NSW) 90.], or from the placing of items upon a road which create a danger [ Thompson v Bankstown Corporation (1953) 87 CLR 619.], or the removal of items which protect against danger [ Flukes v Paddington Municipal Council (1915) 15 SR (NSW) 408.].
[160] In dealing with questions of breach of duty, whilst there is to be taken into account as a "variable factor" the results of "inadvertence" and "thoughtlessness" [ Smith v The Broken Hill Pty Co Ltd (1957) 97 CLR 337 at 343.] , a proper starting point may be the proposition that the persons using the road will themselves take ordinary care [ Miller v McKeon (1905) 3 CLR 50 at 60.] .
56 Smith v. Broken Hill Proprietary Co Ltd (1957) 97 CLR 337 at 343 illustrates the difference between inadvertence and thoughtlessness. Their Honours gave as authority for their proposition about the proper starting point a passage in Miller v. McKeon (1905) 3 CLR 50 at 60. In Miller the High Court (Griffiths CJ, Barton and O'Connor JJ) dealt with a case which was alleged to be based on misfeasance: a country road ran through a cutting with steep sides up to 10 feet high; the plaintiff, a passenger in a buggy travelling at night without lights, got out of the buggy to locate the entry to the cutting; unknown to him the buggy had been driven up the bank to one side of the cutting, and in the dark he fell over the edge and was injured. It was alleged that there was negligence in the construction of the cutting in that the access up the bank at the side was not blocked off by a fence. Griffiths CJ said at 60: (and I have emphasised some words)
The Government of a new country, forming for the first time a practicable road upon land which has been technically dedicated as a highway, but is impassable for wheeled traffic, is not bound by the rules which govern persons (other than the highway authority) who interfere with the surface of an ancient highway, as that term is understood in England. If the Government improve the so-called highway, and render it more useful to the public than it previously was, they are not guilty of a misfeasance merely on the ground that they have interfered with a highway. The analogy is rather to the case of a private owner who invites the public to pass through his land by a track which he has there constructed, and which is reasonably safe for persons using ordinary care. If such an owner, after granting the permission, puts, or allows to be put upon the track which he so offers, a new obstacle or danger by which persons using reasonable care would be liable to be injured, he is liable for the consequences: Corby v. Hi ll [ 4 C.B. N.S., 556; 27 L.J. C.P., 318. ]. But in the absence of such acts of commission, he is not liable merely by reason of the imperfections of the road which he offers. So the Government of a newly-settled country, which undertakes the first formation of a road, whether the soil has or has not been formally dedicated as a highway, is bound to use such care to avoid danger to persons using it as is reasonable under all the circumstances. These circumstances include the nature of the locality, the extent of the settlement, the probabilities as to the persons by whom the road is likely to be used, and the moneys available to the Government for the purpose; it being always assumed that the persons using the road will themselves take ordinary care . If the Government use such care they are not guilty of misfeasance. And if, by reason of altered circumstances, the conditions of the locality become such that, if the road were to be made anew, further precautions might reasonably be taken, the original act does not therefore become unlawful.
57 In the leading judgment in Brodie at 581 [163] Gaudron, McHugh and Gummow JJ also said:
[163] The formulation of the duty in terms which require that a road be safe not in all circumstances but for users exercising reasonable care for their own safety is even more important where, as in Ghantous , the plaintiff was a pedestrian. In general, such persons are more able to see and avoid imperfections in a road surface. It is the nature of walking in the outdoors that the ground may not be as even, flat or smooth as other surfaces. As Callinan J points out in his reasons in Ghantous , persons ordinarily will be expected to exercise sufficient care by looking where they are going and perceiving and avoiding obvious hazards, such as uneven paving stones, tree roots or holes. Of course, some allowance must be made for inadvertence. Certain dangers may not readily be perceived because of inadequate lighting or the nature of the danger (as in Webb v. The State of South Australia [(1982) 56 ALJR 912; 43 ALR 465.]]), or the surrounding area (as in Buckle , where the hole was concealed by grass [(1936) 57 CLR 259 at 266.]). In such circumstances, there may be a foresee able risk of harm even to persons taking reasonable care for their own safety. These hazards will include dangers in the nature of a "trap" or, as Jordan CJ put it, "of a kind calling for some protection or warning"[ Searle v Metropolitan Water, Sewerage and Drainage Board (1936) 13 LGR 115 at 117. ]. In Romeo , Toohey and Gummow JJ noted in a different context that the care to be expected of members of the public is related to the obviousness of the danger[302]. Kirby J pointed out in the same case that even an occupier of premises "is generally entitled to assume that most entrants will take reasonable care for their own safety"[ (1998) 192 CLR 431 at 455 [52]. ]. Each case will, of course, turn on its own facts[304].
