Orders
37 I agree with the orders proposed by Handley AJA.
38 HANDLEY AJA: About 1am on 3 July 2000 a Toyota Hiace van driven by Mr Dominello (the first defendant) ran off the Pacific Highway 16 km south of Grafton and hit a tree injuring Mrs Dominello who was in the front passenger seat. She sued the first defendant and the Nominal Defendant for damages. The trial Judge, Balla DCJ, awarded her $2,775,035 against the first defendant but found for the Nominal Defendant. The first defendant has appealed from the finding of liability, and Mrs Dominello has appealed from the judgment in favour of the Nominal Defendant. The assessment of damages has not been challenged.
39 The first defendant was taking his wife and eight children back to Sydney, and their luggage was in a box trailer being towed by the van. They stopped in Grafton for petrol, drinks and sandwiches and continued. 16 km south of Grafton the highway crosses a crest and takes a reverse curve downhill at a grade of 7-8%, first to the right, and then to the left. The speed limit was 100 kph but there was an 85 kph advisory speed sign.
40 There had been light rain throughout the night, and the road was wet, but it was not raining at the time of the accident. The first defendant lost control of the van on the left-hand curve, when it slid first to the right and then to the left, before running off the carriage way and hitting a tree.
41 The Judge found without "hesitation" that diesel fuel had been spilt on the south-bound lane. Constable Szlicht, who arrived ten to twelve minutes after the accident, and approached with caution at 70 to 75 kph, momentarily lost control of his vehicle on the left-hand curve and it crossed the centre line. Mr Toovey of the State Emergency Services arrived shortly afterwards. He momentarily lost control on the left hand curve at 50 kph and his vehicle also crossed the centre line.
42 The Judge found that a substantial quantity of diesel had fallen from a south-bound vehicle onto "a relatively short section" of the south-bound carriage way. The first defendant encountered this when he drove through the left hand curve. Passing vehicles, and the wet surface then spread the diesel along the highway.
43 Mr Robertson, a tow-truck driver, who arrived before the Police, SES and RTA vehicles (Black 38) drove to near the accident scene (Black 38). At that time the diesel was spread over about 100 metres (Black 46). He later reversed his tow-truck back up the hill and switched on his safety beacon to warn south-bound traffic (Black 38-9).
44 Mr Appleby from the RTA noticed diesel on the south-bound carriage way at the apex or start of the right-hand curve (Black 54, compare 75-6) near the top of the hill (Black 56). RTA staff later spread sand over the south-bound lane to mop up the diesel. It was spread from near the crest where the RTA truck had stopped (Black 72) to the bottom of the hill beyond the accident site (Black 54-5, 56-7, 61, 64, 67, 70-1, 75-6), a distance of 400 metres (Black 64) "where we could actually see something on the road" (Black 65).
45 The tow-truck had backed up to the crest of the hill in the south-bound lane, and would probably have spread diesel back up the road towards the crest. Mr Robertson noticed diesel near the crest when he got out of his truck (Blue 115, compare Black 39) and it was later noticed a little below the crest by the RTA staff.
Liability of the first defendant
46 The Judge said that as the first defendant drove downhill into the right hand curve the engine noise increased, that his speed was increasing, and he was travelling at around the speed limit of 100 kph when he lost control. He was travelling too slowly to have lost control simply because the road was wet (Red 59E), and he did so because the diesel made the road surface "very slippery".
47 The first defendant did not see the 85 kph advisory speed sign. According to the Road Users Handbook such a sign shows "the maximum speed that is safe in good conditions". The recommended speed is conservative. He agreed in cross-examination that bearing in mind the weather, and the van with its trailer, he would want to be travelling a little below the advisory speed. The Judge found that "a driver taking reasonable care would have been driving at 75 to 80 kph at the point where the first defendant lost control of the van".
48 There was evidence, which the Judge accepted, that drivers could lose control of their vehicles on the diesel affected areas at relatively slow speeds. The Judge found that the first defendant would have regained control of his van almost immediately if he had been travelling at 75 to 80 kph. She found a causal relationship between the speed of the van, which increased the risk of injury to the plaintiff, and the accident, and held that the first defendant had been in breach of his duty of care to her.
49 Expert evidence was given by Mr Joy for the plaintiff and by Mr Jamieson for the first defendant. Mr Jamieson concluded that the critical or slide off speed on the left-hand curve in dry conditions was about 150 kph, while in "normal" wet conditions it would be about 110 kph (Blue 158). Mr Joy agreed (Blue 68).
50 The Judge was not prepared to accept the experts' opinions about the speed at which a driver would not have lost control on a surface contaminated by a spill of diesel because of the absence of relevant scientific studies (Red 61). This finding was not challenged.
51 The Judge's finding that the first defendant's speed of about 100 kph was a cause of the accident because it increased the risk of injury was fundamentally flawed. It was inconsistent with her findings that "the first defendant lost control of the van because the diesel made the road surface slippery" (Red 59, 63), and that he would not have lost control "simply becaue the roadway was wet" (Red 59).
52 Driving at a higher speed always increases the risk of injury. Driving at 60 kph within the speed limit is more likely to injure somebody in any emergency than driving at 50 kph. It will almost always be more prudent and safer to driver at a lower speed, but this cannot, without more, constitute a failure to take reasonable care.
53 The first defendant could not foresee the presence of the diesel fuel on the left-hand curve and was not required to drive from Queensland to Sydney at a speed which would enable him to meet such conditions with safety. The presence of the diesel would have been dangerous for this van and trailer at much slower speeds. According to Mr Clare the Police vehicle, which had been travelling at 70 to 75 kph, went past sideways: "They'd actually lost it big time" (Black 272, 277). If the first defendant had lost control in the same way the heavily loaded box trailer may have prevented any recovery: (Jamieson Blue 164, 165).
54 The Judge's findings that "It would be more appropriate to be driving a little below" the advisory speed (Red 60) and that a driver "taking reasonable care" would have been driving at 75 to 80 kph (61) do not establish the converse, that it was a breach of duty to be travelling at more than 80 kph.
55 Was it negligent for the first defendant to be driving at the speed limit in the conditions known to him, or reasonably foreseeable? The fact that he was driving at 100 kph would not, without more, have caused a loss of control. He would have negotiated this curve in safety, with a substantial margin, but for the presence of the diesel.
56 Although, but for his speed, the accident would not have happened, this does not establish causation. In March v Stramare (E&MH) Pty Ltd [1991] HCA 12; (1991) 171 CLR 506, 516 Mason CJ said:
"The 'but for' test gives rise to a well-known difficulty … where there are two or more acts or events which would each be sufficient to bring about the plaintiff's injury. The application of the test 'gives the result contrary to commonsense, that neither is cause'. … In truth, the application of the test proved to be either inadequate or troublesome in various situations in which there are multiple acts or events leading to the plaintiff's injury … The cases demonstrate the lesson of experience, mainly, that the test, applied as an exclusive criterion of causation, yields unacceptable results and that the results … must be tempered by the making of value judgments and the infusion of policy considerations."
57 In the same case Deane J said at 523:
"… the mere fact that something constitutes an essential condition (in the 'but for' sense) of an occurrence does not mean that, for the purposes of ascribing responsibility or fault, it is properly to be seen as a 'cause' of that occurrence as a matter of ordinary language or commonsense."
58 Similarly in Fitzgerald v Penn [1954] HCA 74; (1954) 91 CLR 268, 276 Dixon CJ, Fullagar and Kitto JJ said:
… there will not seldom be cases in which the attention of the jury ought to be called by the Judge to the question whether a particular act or omission, which they may regard as negligent, can fairly and properly be considered a cause of the accident. Such a case came recently before this Court in Skewes v Public Curator of Queensland … a head-on collision had taken place while two motorcars were being driven at a fast rate in a cloud of dust which temporarily almost destroyed visibility. Driver A was on his correct side of the road, driver B on his wrong side. The action was in fact tried by a judge without a jury, but, if there had been a jury, it would clearly in the circumstances … have been open to them to say that both driver A and driver B were negligent in driving too fast, but that the negligence of driver A was not a 'cause' of the collision, which would have happened with the same results if he had been driving at a reasonable speed."
59 In this case it can also be said that, given the findings of the trial Judge, this accident would have happened with the same results if the first defendant had been driving at any speed above 80 kph. His speed of 100 kph was a necessary but not a sufficient condition for this accident. The presence of the diesel was a sufficient cause at any speed above 80 kph.
60 The speech of Lord du Parcq in Grant v Sun Shipping Co. Ltd [1948] AC 549, 563 established that the negligence of one party which would not have caused the plaintiff's injury but for the subsequent negligence of another does not exclude a finding that the earlier negligence was a cause of the injury. As Mason CJ said in March v Stramare (E&MH) Pty Ltd (above) at 512:
"… courts readily recognize that there are concurrent and successive causes of damage on the footing that liability would be apportioned as between the wrongdoers. The modern approach is exemplified by Lord du Parcq in his speech in Grant v Sun Shipping Co. Ltd ".
61 In Grant's case the negligence of the ship repairers was a sufficient cause of the fall of the stevedore into the open unlit hatch, as was the later negligence of the ship's officers in failing to detect the source of danger and take appropriate action.
62 The critical question here is whether reasonable care required the first defendant to drive 20 kph below the speed limit so that it was negligent to be driving at more than 80 kph. The Judge's findings do not directly address that question. Moreover the evidence that Mr Toovey and Constable Szlicht temporarily lost control of their vehicles casts doubt on the finding that the first defendant would have avoided this accident by travelling at 80 kph.
63 The accident would not have happened "but for" the unforeseeable presence of the diesel spill. As the Judge found, the wet conditions alone would not have caused the first defendant to lose control on that curve.
64 The advisory speed sign was not there to warn motorists of the presence of diesel fuel on the carriageway. It was there to warn of the curve, but the advisory speed was 25 kph lower than the critical or slide off speed of 110 kph. While driving at or below the advisory speed would have been safe that speed was extremely conservative, and I am not prepared to hold that the first defendant was negligent by driving at more than 80 kph as the judge found, or by driving on the speed limit which would normally have been quite safe.
65 In my judgment the principle established in Grant v Sun Shipping Co. Ltd does not apply in this case. In fact the position of the first defendant is analogous to that of the plaintiff stevedore who was not guilty of contributory negligence despite falling at night into a hatch left open and unlit as a result of the negligence of the ship's repairers and ship's officers.
66 In my judgment therefore the first defendant's appeal succeeds and judgment should be entered for him in the action.
Liability of Nominal Defendant
67 The plaintiff's case against the Nominal Defendant was that the diesel fuel had spilled from an unidentified heavy truck as it drove down the left hand curve because a cap on its fuel tank had not been replaced, or properly replaced, after the driver refuelled his vehicle at Grafton.
68 This raised two questions, first, whether that was the more probable inference from the facts that were established, and, second, whether the plaintiff's injuries were within the definition in s 3 of the Motor Accidents Compensation Act 1999 (the Act), and the Nominal Defendant's liability in respect of unidentified motor vehicles in s 34.
69 The Judge was satisfied that at the time the Highway was mainly being used by heavy vehicles fitted with diesel tanks. The outlets where diesel was being sold in Grafton at that time of night were all self-service. A service station attendant could not have been responsible for any failure to properly replace the fuel cap.
70 Paragraphs [29]-[34] are substantially based on her Honour's primary findings which were not challenged. Heavy vehicles are commonly fitted with multiple fuel tanks, generally two, and they can be driven although the cap on one or more of those tanks has not been replaced. When the tanks are full the fuel reaches within an inch or two of the wide filler opening. It can slosh about when the truck is in motion.
71 Constable Szlicht said the diesel at the scene of the accident was consistent with a refuelled vehicle leaving Grafton with an open or partially open fuel tank. This would permit a large quantity of diesel to spill out on what was the first sharp down hill bend to the south.
72 Other possible causes were canvassed in the evidence. The Judge found that it was "unlikely" that diesel could escape from a 4WD because the neck from the filler to the tank in such vehicles is usually about 18 to 24 inches long. Such a vehicle might have an auxiliary tank which was not cross connected, and if that tank was ruptured near the top, the diesel could escape and leave a deposit similar to that encountered by the first defendant.
73 Fuel can also escape from a heavy truck if a tank is holed, or there is a break in the fuel line but neither of these situations was "consistent with" a heavy isolated deposit. A large hole would drain the tank causing the vehicle to rapidly run out of fuel, and a small hole, or broken fuel line would produce a much lighter and longer deposit, or a spray (Black 137).
74 Diesel can also be spilled from a fuel transport vehicle as a result of a crack in the weld of its tank. A hairline crack would allow the fuel to drip out, while a sudden and total failure of the tank would produce a heavy but isolated deposit. It the delivery hose was left in the wrong position fuel could drain from the hose. An isolating valve would limit any spill to the contents of the hose. If the fuel cap was left off the tank in such a vehicle, or was not properly secured, fuel could spill out in the same way and in the same quantity as from an uncapped tank on a heavy truck. Such a tanker could have been filled at a refinery or industrial fuel depot by someone other than the driver.
75 Some heavy trucks have an auxiliary fuel tank that may not be cross connected with the main fuel tanks, although this was unusual (Black 351). A poorly fitted cap could gradually work loose from vibration allowing the fuel to spill out on a bend such as this one.
76 The Judge said that the inference relied on by the plaintiff was only one of many that were available and diesel could escape from vehicles in a number of ways without the negligence of the owner or driver. She therefore held that "it is not possible to say that the spill would not ordinarily have occurred without negligence".
77 She said that if the spillage occurred in the manner contended for by counsel for the plaintiff it could not be said on the balance of probabilities that it had resulted from an act of the driver. The vehicle could have been filled by the previous driver or in a private depot by any employee.
78 Her Honour's analysis of the competing inferences was, in important respects, contrary to undisputed evidence and otherwise flawed.
79 At that time there were no private depots in the Grafton area which carried stocks of fuel for sale to passing vehicles (Wren Black 147). There is thus a significant inconsistency in her Honour's findings. At Red 65 she found that at that time of night all the outlets selling diesel in the Grafton area were self-service but at Red 69 she said that the offending vehicle could have been filled at a private depot by an employee.
80 Heavy trucks which left Queensland with an uncapped or poorly capped fuel tank would either have spilled fuel earlier in the journey or used enough by the time they reached this left hand bend to "reduce markedly" the likelihood of a spillage such as this (Joy Black 350).
81 Heavy vehicles with diesel tanks made up the bulk of the south bound traffic at that time. If these vehicles were refuelled in Grafton this would have been done by their drivers at self-service outlets.
82 It was not suggested that the spillage could have come from an open filler on a commercial fuel tanker and there was no evidence that any of the oil companies had a fuel depot in Grafton. There was evidence about the possibility of a sudden rupture of the tank on such a vehicle but this would have caused a much heavier spill over a longer distance. A crack in the welding of the tank on such a vehicle would not have caused the heavy, but isolated, deposit observed by the witnesses.
83 Another possible source of the spill was an industrial tanker used to refuel earth moving and construction equipment on site (Joy Black 313). There was no apparent reason for such a vehicle to be on the road at this hour of the night. It could have been needed if night work was then in progress to the south, but Mr Wren who drove to Coffs Harbour later that night, did not say anything about work on the Highway to the south. Mr Appleby, the district works supervisor for the RTA, who was responsible for the construction and maintenance of the Highway in his area (Blue 117), was not asked if there was work on the Highway that night.
84 The hypothesis that this spill could have come from a hole, crack, or hose on an industrial tanker driven through this curve shortly before the accident is pure speculation.
85 The hypothesis that the spill came from a fuel tank on a heavy vehicle as a result of a sudden rupture or impact can also be discounted. Mr Wren did not see any broken down truck on the Highway south of the accident site (Black 131, Joy Black 349).
86 Mr Wren saw another diesel spill on the next steep bend on the Highway on the Corindi Range 20 kms to the south (Blue 141). No other diesel spill in the Grafton area was reported to the Police or the RTA that night (Black 57, 105, Blue 119).
87 In my judgment alternative hypotheses that the spill came from a 4WD, an industrial tanker, or from a sudden rupture or weld failure on a fuel tank are either not open on the evidence or are highly improbable.
88 The remaining inference, not excluded by the evidence, is that the spillage came from the failure of a refueller to replace or properly replace the cap on the diesel tank of a heavy vehicle. The Nominal Defendant could only be liable if the refueller was a driver. Contrary to the Judge's view (Red 69) it would not matter if this was a previous driver. It would matter if the refueller was someone other than a driver.
89 Refuelling at Grafton at that hour of the night must have been done by the driver at a self-service outlet. The possibility that the spill at that hour came from an industrial tanker can be discounted for the reasons already given. The possibility that the absent or badly fitted cap was the fault of a refueller in Brisbane, other than a driver, can also be discounted because the fuel in the tanks would have been reduced to a safe level by prior spillage and normal consumption long before this bend.
90 This means that the remaining hypothesis contended for by the plaintiff is more probable than the others, collectively and individually.
91 The presence of the spill on the first significant downhill curve south of Grafton and the absence of a similar spillage on the previous 16 kms, or on the next 20 kms to the south, or on the steep section of the Highway north of Grafton leads to the inference that something happened in Grafton. Something that caused a fuel spill on this reverse bend where the super elevation, first to the right, and then to the left (Blue 40) would cause the fuel to slosh about in the tank.
92 The legal test in such a case is that referred to in Luxton v Vines [1952] HCA 19; (1952) 85 CLR 352, 358:
… many hypotheses may be put which the evidence does not exclude positively. But this is a civil and not a criminal case. We are concerned with probabilities, not with possibilities. … where direct proof is not available, it is enough if the circumstances appearing in evidence give rise to a reasonable and definite inference: they must do more than give rise to conflicting inferences of equal degrees of probability so that the choice between them is mere matter of conjecture … But if circumstances are proved in which it is reasonable to find a balance of probabilities in favour of the conclusion sought then, though the conclusion may fall short of certainty, it is not to be regarded as a mere conjecture or surmise.
93 In my judgment the evidence supports the existence of a full fuel tank on a heavy truck with an open filler as the most probable source of this spill. More probably than not the open filler would be the result of the driver's negligence in failing to replace or properly replace the fuel cap.
94 This is an ultimate conclusion which is for the Court, rather than a witness, but if it matters the police officer (Black 125-6), Mr Joy (Blue 51), and Mr Jamieson (Blue 163) all reached the same conclusion.
The Act
95 The trial Judge did not have to consider whether the Nominal Defendant was responsible for the negligence of the driver of the unidentified heavy motor vehicle in failing to replace, or properly replace, one of the fuel caps on his vehicle. This was the subject of a Notice of Contention from the Nominal Defendant and must now be considered in view of the findings proposed.
96 Section 34(1) of the Act provides:
"(1) An action for the recovery of damages in respect of the death of or injury to a person caused by the fault of the owner or driver of a motor vehicle in the use or operation of the vehicle on a road in New South Wales may, if the identity of the vehicle cannot after due inquiry and search be established, be brought against the Nominal Defendant".
97 Para (a) of the definition of injury in s 3 reads:
"… means personal or bodily injury caused by the fault of the owner or driver of a motor vehicle in the use or operation of the vehicle if, and only if, the injury is a result of and is caused during:
(i) the driving of the vehicle, or
(ii) a collision, or action taken to avoid a collision, with the vehicle, or
(iii) the vehicle's running out of control, or
(iv) such use or operation by a defect in the vehicle … "
98 This requires the injury to be "caused by the fault of the owner or driver of a motor vehicle", and "in the use or operation of the vehicle". The latter is defined in s 3 as including "the maintenance … of the vehicle".
99 The first causal requirement is that the injury must be caused by fault "in the use or operation of the vehicle". The second, which includes a temporal element, is that it must be "the result of and … caused during" one of the activities, events, or situations referred to in the subparagraphs.
100 Mr Gross QC, for the Nominal Defendant, submitted that the definition required the injury and the fault to both occur during one of those activities, events, or situations, and this had not happened.
101 In my judgment there is no such temporal requirement. The relevant requirements are for the injury to be caused by the fault of a relevant person (owner or driver), in a relevant activity (use or operation) but only if that injury was caused during another relevant activity, event, or situation (the subparagraphs).
102 On the findings proposed these requirements are satisfied. The inferred fault is that of the driver of the unidentified vehicle and it occurred in the use of the vehicle. Refuelling a vehicle, which enables it to be driven, is part of its maintenance, and part of its use. Although the vehicle is not being driven while it is being refuelled, it is being used to receive and hold the fuel just as it may be used to receive and hold chattels or passengers. The plaintiff's injury was the result of the driving of the unidentified vehicle, and caused when the driving caused the spill. The injury was also caused by the driver's fault during the driving when he failed to remember that he had not replaced the fuel cap and stop his vehicle to do this.
103 The injury was also caused by the driver's fault during the driving of the vehicle by a defect in the vehicle, its open fuel tank. The fuel cap is an important part of the vehicle because it can prevent loss of fuel by spillage and its contamination by airborne material. A vehicle without a fuel cap has a defect and it has another if an available fuel cap is not fitted, or not properly fitted.
104 The Court was referred to a number of reported and unreported decisions on the meaning and application of these definitions. The facts of those cases are remote from the facts of the present case. Most of the cases explore the boundary between the liability of an owner under the Act, and his liability outside the Act for failure to maintain a safe system of work. They also involved defects of a very different kind.
105 However Allianz Australia Insurance Ltd v GSF Pty Ltd [2005] HCA 26; (2005) 221 CLR 568 contains a helpful analysis of this definition of injury in an earlier statute.
106 The mechanical unloading mechanism on a truck was defective, and the employer instructed its employee to unload the truck manually. In doing so the employee injured his back. It was common ground that there was "a defect in the vehicle" but the Court held unanimously that the operative cause of the injury was not the defect, but the negligent direction of the employer.
107 McHugh J said (para [54]) that there had to "be a finding that, of the entire set of circumstances that contributed to the injury, it was 'a defect in the vehicle' that caused the injury". He added (para [61]) that "… there must be a close physical connection between the defect and the injury". The ratio of his decision was in paras [58]-[59]:
… two matters contributed to bring about Mr Oliver's injury:
