Breach of common law duty of care
148 As I have mentioned, the sole breach for which the appellants contend is that the respondent should have instructed Mr Kelman to remove the tarpaulin before offloading the grain.
149 It is worth noting what is not alleged against the respondent.
150 Firstly, as I have mentioned, the appellants did not persist in the argument raised at trial that the respondent breached its duty because it permitted Mr Kelman to work near unguarded machinery.
151 Secondly, there was no challenge to the finding that the respondent did not know about the hazard constituted by the unguarded auger. The appellants relied solely on imputed or constructive knowledge.
152 Thirdly, the appellants did not contend that the respondent should have warned Mr Kelman specifically about the possible existence of unguarded clutches on augers.
153 Fourthly, the appellants did not contend that the respondent should have told Mr Kelman that he was not required to effect any delivery (even if that meant that the respondent would lose the business) which required the use of an auger with an unguarded clutch in circumstances where the space between the auger and the back of the truck was so small as to create a risk to his personal safety.
154 Fifthly, the appellants did not contend that the respondent should have told Mr Kelman that he was not required to effect any delivery (even if that meant that the respondent would lose the business) if any equipment supplied by the recipient for the purposes of effecting delivery was dangerous and might create a risk to his personal safety.
155 As a matter of common knowledge, there is no standardised equipment required (or used) for the delivery of grain to silos on farms. Generally, farmers have their own idiosyncratic systems. The quality, mechanism and length of an auger would differ from farm to farm. The distance between the back of the delivery truck and trailer and the auger would depend on the particular equipment used by the individual farmer. Thus, that distance would vary from farm to farm.
156 In other words, the appellants' sole case in regard to breach of the duty of care was that the respondent should have told Mr Kelman that, in all circumstances, irrespective of the weather and the length of the auger, if an auger were to contain an unguarded clutch or unguarded revolving machinery, he was required to lift and roll back the tarpaulin before the auger was switched on.
157 It immediately comes to mind that this argument pays no regard to the fact that, in windy or wet conditions, grain might be lost or spoiled. Plainly, the driver's safety is far more important than the loss of grain, but it is problematic to lay down an absolute requirement without regard to considerations of reasonableness.
158 Further, the appellants' arguments must be understood in the context of the fact that, as his Honour found, the danger constituted by the auger was obvious to all who observed it (including Mr Kelman and Mr Mutton) and Mr Kelman was well aware of it.
159 Harrison v Lau Nay Nominees Pty Limited [2004] NSWCA 18 is relevant as it bears some similarities to the present case. Harrison concerned an injury sustained by an experienced truck driver, Mr Harrison, while redistributing a load on a trailer. Meagher JA (with whom McColl JA and I, on this issue, agreed) said (at [11] to [12]):
"Mr Harrison gave evidence that he had from the age of 16 years worked on or with trucks and had secured a truck driver's licence by the age of 18. He said he had extensive experience in the loading and unloading of trucks and in the driving and transportation of fully loaded vehicles; and that it was because of his skill and experience that he sought and obtained employment with the first respondent. In these circumstances, there was no 'delegation' of anything by his employer to him, but … a sensible recognition by his employer of his expertise. The situation in this case has nothing in common with the situation in McLean v Tedman (1984) 155 CLR 306 at 311, when … Mason, Wilson, Brennan and Dawson JJ said: 'It is not an acceptable answer to assert that an employee has no control over an employee's negligence or inadvertence'.
As Mr Little SC, learned senior counsel for the first respondent, said:
'This is not a case where it can be suggested that a safety officer travel to every site before the truck gets there to see that the loads are safe to pick up'".
160 Prior to the accident, Mr Mutton had never seen a driver attempt to roll back a tarpaulin after offloading had commenced. Plainly, in windy conditions, once the grain load, or part of it, is exposed, it can blow all over the place. Whether or not it was standard practice to delay moving the tarpaulin to the last possible moment in such weather conditions was not explored in the evidence. Mr Kelman, a very experienced driver, was well aware of the risk and thought that this was an appropriate way to proceed. Mr Mutton, a farmer of many years standing and who had, for many years, observed grain being offloaded while he operated the auger, thought that there was nothing untoward about what Mr Kelman was doing.
161 The respondent pointed to the fact that an operation of the kind Mr Kelman was conducting when he was injured had been safely carried on, without incident, about four or five times a year for some 22 years. The appellants sought to answer this by submitting that it was to be inferred (from Mr Mutton's evidence) that on previous occasions the tarpaulin had been wound back before the offloading commenced.
162 The evidence does not reveal whether Mr Mutton was the only person who supervised offloading of grain on the appellants' behalf. He said that before the accident he had observed a number of other drivers deliver grain to the silo. He said "usually" before they backed their vehicle in they would undo the tarpaulin and roll it back about a metre or so. Mr Mutton said that when a truck arrived either he, or his brother, or "whoever might have been around" would stay with the driver at the rear of the truck. Thus, the evidence did not reveal whether it was an invariable practice for drivers to wind back the tarpaulin before commencing the offloading of grain.
163 The respondent submitted that, irrespective of whether a driver removed the tarpaulin before or after offloading commenced, during every offloading operation and while the auger was operating, the driver was required to walk between the rear of the tray and the auger more than once (and probably two or three times). This was because the driver needed to adjust the elevation of the tray from time-to-time and, in order to ensure that the new elevation was appropriate, was required to adjust the grain door each time the elevation was adjusted.
164 I have mentioned that the handle that opened or closed the grain door was immediately to the right of the grain door. Thus, to get to the handle the driver had to go behind the tray on its right-hand-side in order to grasp it. The handle needed to be operated (and the grain door opened and closed) while the driver was adjusting the flow of grain through the door. As I have observed, this was an ongoing process. The following exchange in the cross-examination of Mr Kelman explains what occurred in this regard.
"Q. From time to time during that process you would have to walk around and get into the cab to adjust the tipper?
A. Yes.
Q. You did that a couple of times?
A. Yes.
Q. At other times you would have to go right around to the other side to adjust the flow through the grain door?
A. Yes.
Q. Was that something which at different stages during the unloading you had to do a few times?
A. Yes, usually every time you put the body up you go back and just check to make sure the flow wasn't coming out too quick. Just adjust the door.
Q. I suppose also in-between adjustments of the tipper you would be opening the grain door a bit further as the load got less?
A. Yes, it does vary a little bit, yes.
Q. So that was something you had to do a few times?
A. Yeah.
Q. Certainly more often that adjusting the tipper?
A. Yeah, yeah.
Q. Every time that you had to adjust the grain door you would have to walk in-between the back of the truck and the tractor and the PTO running up to the auger?
A. Yes.
Q. In the period between the last time that you adjusted the tipper to increase the angle and the time this accident occurred, had you gone to the back of the truck to the area where the grain door handle was?
A. Yes.
Q. Had you gone back and stood there during that last part of the unloading process?
A. Yes, because as it gets empty the flow starts to slow down and speed up and, yeah.
Q. It becomes more unpredictable as there is less of a load coming down to the grain door?
A. Yes, yeah.
Q So you had positioned yourself there, I take it, as you did every time you unloaded a load, and presumably as every driver does every time they unload a load of grain?
HIS HONOUR: That is a rather long and complicated question.
HOOKE: It is.
QUESTION WITHDRAWN
Q. You returned to stand there, as you did each time you got towards the end of an unloading process?
A. Yes.
Q. To your observation in the same way that every driver would stand at the end of a load, as it becomes unpredictable that way?
A. Yes, yep."
165 The appellants' riposte was to draw attention to the evidence of Mr Kelman that he crouched down to undo the tarpaulin because of the incline of the tray. This meant that once Mr Kelman had completed untying the ropes (in a crouched position) he could not stand up straight as his head would hit the tray. He therefore moved backwards until his head cleared the tray and then stood up. Having stood up he took another step backwards. Thus, the appellants submitted, he took two steps, one in a crouching position in order that his head would clear the end of the tray, and then, after straightening up, one further step backwards. The appellants submitted that, in these circumstances:
"[T]he entry to, and exit from, the rear of the vehicle was for an entirely different purpose and capable of being undertaken by an entirely different method than that which was chosen by [Mr Kelman] at the time he was injured. That nobody over a period of twenty years or so had been injured notwithstanding the need to regularly adjust the grain door, in circumstances where the tarpaulin was usually removed before unloading began, is eloquent testimony to the fact that the 'tarpaulin or first' practice eliminated, or alternatively significantly reduced, the risk of injury from contact with the auger and clutch. That is because the worker could enter and exit the area at the rear of the truck to adjust the grain flow by crouching, and keeping himself about two metres from the auger."
166 I do not accept the appellants' submissions in this regard. It is true that the operation of opening and closing the grain door differs from unhooking the tarpaulin ropes at the side of the grain door. But, in this context, there is no material difference between the position of the hook on the right of the grain door (and, even on the left) and the handle of the grain door. The method by which the driver would get to the handle of the grain door and open or close it is precisely the same method that he would use in getting to the hooks to release the tarpaulin ropes. The driver would have to crouch down and move forwards until he was sufficiently close to grasp the grain door handle or the tarpaulin rope, depending on his objective. Having completed his particular task, he would move backwards from his position immediately behind the rear of the tray (with the auger at his back) in precisely the same way, irrespective of whether he had been operating the grain door handle or unhooking the ropes.
167 In other words, the exercise of getting between an auger in operation and the inclined rear of the tray was an unavoidable and inevitable part of the work of truck drivers in delivering grain to farmers where the delivery process required the use of an auger (and the use of an auger appears to have been generally ubiquitous). The fact that in the vast majority of instances the driver would be placing himself in this position to open or close the grain door (and not to undo the tarpaulin ropes) is immaterial to the risk to which he would thereby expose himself. The risk in both instances would be the same.
168 There was no evidence to suggest that the method adopted by Mr Kelman in so intruding himself between the rear of the trailer and the grain door was anything other than standard practice in the industry.
169 The fact that over a period of some 22 years no driver sustained any injury in delivering grain to the appellants' farm in circumstances where the same or similar machinery was continuously in use (and there had not even been any suggestion of an accident) becomes highly significant.
170 In Romeo v Conservation Commission of the Northern Territory (1998) 192 CLR 431, Kirby J said (at 481, [132]):
"In determining what risks the defendant was required by law to respond to, it is necessary to have regard to what acts the defendant may have reasonably anticipated in the circumstances. Given the prominence of the danger, past usage of the site and accident experience it was not reasonable to expect the defendant to anticipate the inadvertence of the plaintiff in this case."
171 In Roads and Traffic Authority of New South Wales v Dederer (2007) 81 ALJR 1773, Gummow J (with whom Callinan J (at 1822, [270] and 1823, [282]) and Heydon J (at 1823, [283] agreed) had regard (at 1788, [61]) to the fact that no injury had been caused despite the fact that over some 40 years large numbers of people had jumped and dived from the bridge in question in that case. He considered that the absence of any injury being caused until the plaintiff was rendered paraplegic demonstrated that "the probability [of the risk materialising] was in truth very low". See also at 1790, [71] where Gummow J said:
"The probability of that injury occurring was, however, low. Despite the frequency of jumping and diving from the bridge, no-one was injured until Mr Dederer's unfortunate dive."
172 Callinan J made similar remarks at 1822, [274]. His Honour accepted that diving from the bridge was a risky activity. He said, however:
"But even so, and despite flagrant defiance of the ban, not one out of the many who had dived in the 40 or so years that had elapsed since the construction of the bridge had been injured, so far as anyone could recall, let alone severely injured. This is to say that the risk, although undisputably [sic] present, had a very low degree of probability of realisation."
173 These observations must apply in the present case. The fact that no accident had occurred in regard to the unguarded auger, despite its constant use over 22 years, indicates that the risk of harm to persons using the auger, although indisputably present, had a very low degree of probability of realisation.
174 The next question is whether the particular risk of harm should have been foreseen. By reason of s 3B(1)(f) of the Civil Liability Act 2002 (NSW), that Act does not apply in respect of the civil liability of the respondent to Mr Kelman. Hence, the well known test derived from Mason J's remarks in Wyong Shire Council v Shirt (1980) 146 CLR 40 (at 48) is of application.
175 The appellants submitted that the mechanism of the accident - a worker becoming caught in unguarded machinery - was "plainly foreseeable" in the Wyong Shire Council v Shirt sense. That may be accepted, but it does not follow from that alone that doing nothing as regards such a risk was an unreasonable response to that risk.
176 The relevant point was made in Liftronic Pty Limited v Unver (2001) 75 ALJR 867 by McHugh J (with whom Gleeson CJ agreed) when he said (at 871, [25]):
"His Honour and counsel seemed to have proceeded on the erroneous assumption that, if there was a reasonably foreseeable risk of injury to the plaintiff that could have been avoided by using mechanical means, the defendant was necessarily negligent. But the issue in negligence is always whether reasonable care required the elimination of the risk having regard to the consequences of the risk, the probability of its occurrence and the cost, expense and inconvenience of eliminating it."
177 The basic rule was described by Mason J in Wyong Shire Council v Shirt (at 47 to 48) as follows:
"In deciding whether there has a breach of the duty of care the tribunal of fact must first ask itself whether a reasonable man in the defendant's position would have foreseen that his conduct involved a risk of injury to the plaintiff or to a class of persons including the plaintiff. If the answer be in the affirmative, it is then for the tribunal of fact to determine what a reasonable man would do by way of response to the risk. The perception of the reasonable man's response calls for a consideration of the magnitude of the risk and the degree of the probability of its occurrence, along with the expense, difficulty and inconvenience of taking alleviating action and any other conflicting responsibilities which the defendant may have. It is only when these matters are balanced out that the tribunal of fact can confidently assert what is the standard of response to be ascribed to the reasonable man placed in the defendant's position."
178 In Dederer, Gummow J emphasised the need to judge the question of whether reasonable care was exercised prospectively "and not by retrospectively asking whether the defendant's actions could have prevented the plaintiff's injury" (at 1789, [65]). Gummow J quoted the following statement by Hayne J in Vairy v Wyong Shire Council (2005) 223 CLR 422 (at 461, [126]):
"When a plaintiff sues for damages alleging personal injury has been caused by the defendant's negligence, the inquiry about breach of duty must attempt to identify the reasonable person's response to foresight of the risk of occurrence of the injury which the plaintiff suffered. That inquiry must attempt, after the event, to judge what the reasonable person would have done to avoid what is now known to have occurred. Although that judgment must be made after the event it must seek to identify what the response would have been by a person looking forward at the prospect of the risk of injury."
179 In applying these strictures one must commence with the fact that it is common knowledge that machinery utilised by farmers differs from farm to farm in quality, age, safety, reliability and in a host of other features, and can be dangerous in an infinite number of respects. Of course, the drivers of the respondent's 30 trucks would encounter, principally, machinery designed to assist in the process of offloading grain, but even machinery that falls within this limited category must differ in kind in an infinite number of ways in mechanism, configuration, quality, reliability and safety. True it is that augers are dangerous machines and augers with exposed moving parts are even more dangerous. But these dangers are only one of an infinite number that theoretically could involve drivers when delivering grain at farms throughout the eastern part of Australia.
180 As regards the respondent's knowledge of the danger from the auger, the appellants relied on an internal memorandum addressed after Mr Kelman's accident to all drivers of the respondent by Miss Wendy Lamond, a "Rehabilitation Co-ordinator" employed by the respondent. Miss Lamond wrote:
"Factors involved with this accident are:
(1) Exposed moving parts of farm machinery.
(2) Loose flapping clothing.
(3) Windy weather.
(4) Complacency.
The tipper drivers especially would be dealing with grain handling facilities every day, and for this reason complacency is a major issue. Farm machinery as you know is some of the most dangerous equipment around and farmers are renowned for not adhering to all the safety requirements. I am NOT saying that [Mr Kelman's] accident was caused by the farmer, what I am trying to say is be aware of the equipment that is being utilised and consider the dangers involved. Under NO circumstances are any drivers to load or unload grain on farms without the farmer being present to operate the equipment and the farmer is to remain present during the entire loading or unloading process."
181 Miss Lamond's memorandum establishes that it was common knowledge that farm machinery could be very dangerous and "farmers are renowned for not adhering to all the safety requirements". Miss Lamond's letter also emphasises the dangers of complacency.
182 There are several points to be made from this memorandum. Firstly, the warning it gives about equipment is in the most general terms. Secondly, it establishes that the respondent knew that equipment on farms could be dangerous. Thirdly, it does not establish that the respondent knew anything about the particular equipment on the appellants' farm and it makes no reference to the dangers from unguarded augers or other machinery. Fourthly, the appellants' case was not based on any failure on the respondent's part to warn against complacency. Fifthly, Miss Lamond's memorandum instructs drivers to ensure that the farmers are present "during the entire loading or unloading process". Mr Mutton was in fact present throughout the time Mr Kelman was unloading the grain.
183 I would add that Mr Kelman expressly acknowledged that he knew of the danger constituted by the unguarded auger and he was aware of the need to keep a safe distance between himself and the auger. I do not think that the ex post facto warning sent by Miss Lamond in these general terms to all drivers is of material assistance to the appellants in attempting to establish that the respondent was negligent in failing to instruct drivers to roll back the tarpaulins before they commenced offloading grain. It is not directed to this issue.
184 Notionally, it is perhaps arguable that, over the period of many years during which the respondent's drivers delivered grain to the appellants, they must have become aware of the unguarded auger and their knowledge should be attributed to the respondent. This, however, was not a point that was taken at the trial. Sully J found that the respondent did not know of the unguarded auger and there is no appeal against this finding. The appellants contend merely that the respondent should have known of the risk of the existence of an unguarded auger.
185 The fact that Mr Mutton, an experienced observer, saw nothing dangerous in the way that Mr Kelman was setting about his task supports the respondent's contention that what occurred was simply an unfortunate mishap that could not be attributed to a breach of duty on the respondent's part.
186 In Van Der Sluice v Display Craft Pty Limited [2002] NSWCA 204, Heydon JA (with whom Meagher JA and Forster AJA agreed) said (at [83]):
"It is a fallacious reading of Wyong Shire Council v Shirt (1980) 146 CLR 40 at 47 - 48 to conclude that it holds that if the risk of injury is reasonably foreseeable and removal of that risk by simple and cheap measures is possible but not undertaken, there is a breach of duty. Mason J left open as the response of a reasonable person the course of doing nothing instead of adopting the simple and cheap measures: Council of the Municipality of Waverley v Lodge [2001] NSWCA 439 at [29]."
187 The response of the respondent to the general risks of danger that Mr Kelman might encounter on farms (including the general risks of machinery not properly guarded), and the particular risks of him having to work with unguarded augers, was to do nothing (save for being satisfied that Mr Kelman was a very experienced driver and had considerable experience in working with augers). I am not persuaded that this response was unreasonable. I would dismiss the appeal against Sully J's decision in regard to the appellants' case based on a breach by the respondent of the duty of care it owed Mr Kelman.
