45 SACKVILLE AJA:: I gratefully adopt Giles JA's statement of the facts and of the relevant statutory provisions.
46 The only issue on the appeal is whether the injuries sustained by the respondent were caused by the fault of the owner of the tractor "in the use or operation of the tractor". The quoted expression was used, at the relevant times, in s 122 of the Motor Accidents Compensation Act 1999 (NSW) ("MACA Act") and in the definition of 'injury" in s 3 of the MACA Act. Both provisions are set out in the judgment of Giles JA.
47 On the findings made by the primary Judge, the fault of the owner consisted of instructing the respondent to lower the roll bar when driving the tractor in the orchard. Had the roll bar been in position, so his Honour found, the injury to the respondent would not have occurred.
48 In Allianz Australia Insurance Ltd v GSF Australia Pty Ltd (2005) 221 CLR 568 ("Allianz"), the facts of which have been referred to by Giles JA, the employer conceded that the employee's injuries had been caused by the fault of the owner in the use or operation of the vehicle (in that case, a truck modified to facilitate the unloading of airline containers): at 595 [87]. It was therefore not strictly necessary for the Court to consider the meaning of the introductory words in the definition of "injury": in s 3 of the MACA Act viz "injury caused by the fault of the owner … of a motor vehicle in the use or operation of the vehicle".
49 The joint judgment of Gummow, Hayne and Heydon JJ in Allianz did not address the construction of the introductory words. However, their Honours said that the "evident purpose" of the 1995 amending legislation (which inserted the new definition of "injury" into the Motor Accidents Act 1988 (NSW)) was:
"to limit the definition of injury by its cause and to narrow what the legislature considered the overbroad reading in the case law of the expression in s 69 [of the Motor Accidents Act 1988 (NSW)] caused by the fault of the owner or driver of a motor vehicle in the use or operation of the vehicle".
50 Only McHugh J considered what he described as "the first aspect of causation". His Honour divided (at 576 [19]) the relevant part of the definition of "injury" ("caused by the fault of the owner … in the use or operation of the vehicle") into three component parts:
· there must be fault of the owner;
· that fault must be in the use or operation of the vehicle; and
· the injury must be "caused by" the fault of the owner in that use or operation.
51 McHugh J expressly accepted (at 576 [21]) that the word "in" when used as part of the expression "in the use or operation of the vehicle", simply means "in relation to" or "in the course of". His Honour thought this construction to be correct because:
"the words focus on the fault of the owner in its capacity of owner. Failure by the owner to fix the defective unloading mechanism satisfies this requirement, as would a direction to use an unsafe system of work to unload the vehicle ". (Emphasis added.)
52 Later in his judgment (at 587 [56]), McHugh J concluded that the first aspect of the definition had been satisfied on the facts because:
"GSF failed to maintain the vehicle and negligently instructed its employees to unload the vehicle despite the vehicle's unloading mechanism being out of operation". (Emphasis added.)
53 McHugh J appears to have adopted a broad interpretation of "the first aspect of causation" incorporated in the definition of "injury". However, a narrower view was taken by the majority in Nominal Defendant v GLG Australia Pty Ltd (2006) 228 CLR 529 ("GLG"), although without any express reference to McHugh J's analysis. It will be recalled that in GLG the warehouse occupier devised a system for unloading goods from a container which involved a forklift truck going up a ramp to collect a pallet and then reversing down the ramp. An accident occurred inside the container when heavy boxes were dislodged because of vibrations generated by the movement of the forklift truck.
54 In GLG, Gleeson CJ, Gummow, Hayne and Heydon JJ pointed out (at 540 [25]) that the joint judgment in Allianz had "stressed the narrowing effect of the new language employed to define 'injury' in the 1995 Act". Their Honours continued (at 540-541 [27], [29]):
"27 It is true that the occupier was at fault. The fault, however, lay not in the use or operation of the forklift truck, namely, the driving of it . The occupier itself was not driving, nor was the driver it employed driving in a negligent way. The occupier's fault lay in designing and implementing a system of work that involved driving the vehicle in the manner in which it was driven, rather than devising and providing a reasonably safe system of unloading the containers which would not cause vibrations likely to destabilise the boxes being unloaded.
…
29 The flaw in the occupier's contention that the words before 'if, and only if' are to be broadly construed, while any qualification on the breadth of the definition of 'injury' as a whole is to be found in the causative considerations appearing after 'if, and only if', is that the contention gives no weight to the word 'in' in the expression 'in the use or operation of the vehicle'. As counsel for the occupier accepted, 'in the use' here means with respect to , as a consequence of, or by reason of the use of the forklift truck in the circumstances. That is turn points to the need to examine fault in the actual use or operation of the forklift truck at the particular time and place of the injury, and excludes an inquiry that goes more widely to instances of fault in the planning which led to its deployment and which may have taken place at points of time and place remote from those of the injury." (Emphasis added.)
55 The joint judgment in GLG appears (at [27]) to equate the "use or operation" of the forklift truck with the "driving of it". The joint judgment also emphasises (at [29]) the limiting effect of the word "in", when employed as part of the expression "in the use or operation of the vehicle". Nonetheless, their Honours seem to give "in" a broad meaning, interpreting the expression "in the use of" to mean "with respect to … the use of" the motor vehicle. It would appear to follow that the expression "fault of the owner … in the use or operation of the vehicle" embraces the fault of the owner with respect to the use or operation of the vehicle. However, their Honours then say, apparently by way of qualification, that the expression "in the use of" points to the need to examine fault "in the actual use or operation of the forklift truck at the particular time and place of the injury".
56 If I may say so with respect, it is not entirely easy to reconcile all aspects of this reasoning. But the language employed in the joint judgment must be understood by reference to the facts of the case. As their Honours observed (at 541 [31]), the question they faced was one of "characterisation". In resolving this question, they were concerned to distinguish between "fault in the actual use of operation of the forklift at the particular time and place of the injury" and fault by the employer in planning a system of work which led to the deployment of the forklift truck and "which may have taken place at points of time and place remote from those of the injury".
57 The system of work set up by the employer in GLG required the deployment of a forklift truck to assist in unloading the contents of a container. The fault did not lie in creating a situation in which the use or operation of the forklift truck created a particular risk of harm to the operator or to anyone coming in contact with the forklift truck or its contents. The employer's fault in GLG lay in setting up a system in which the forklift truck generated vibrations which dislodged heavy boxes within the container. Presumably any other piece of machinery moving up and down the ramp would have created a similar risk.
58 I do not read the joint judgment in GLG as holding that the "first aspect of causation" in the definition of "injury" can never be satisfied if the employer's fault consists in an act or omission which occurs before the employee is actually injured and at a place other than the place where the injury actually occurs. In the present case, Mr McPherson, on behalf of the appellant, instructed the respondent as to the use of the roll bar early in the respondent's employment. As it happens, Mr McPherson saw the respondent on the day of the accident as he drove from the machinery shed with the roll bar down in accordance with the instructions, but did not countermand his earlier instructions.
59 It seems to me that the important feature of the present case is that the appellant, through Mr McPherson, instructed the respondent not to utilise a critical safety feature of the tractor itself in the course of its ordinary operations. The instruction (and the continuing failure to countermand it) created an unjustified risk of injury to the respondent as the user of the tractor. The appellant's "fault" (that is, the instruction not to engage the roll bar) made the use of the tractor inherently unsafe for any operator (or passenger) and for the respondent in particular. In short, the respondent's instruction and the failure to countermand it went to the manner in which the tractor was to be used or operated as a tractor and necessarily made the use of the tractor hazardous to the operator. I accept, as Giles JA points out, that the positioning of the roll bar did not contribute to the accident. But the positioning of the roll bar made the use or operation of the tractor inherently hazardous and exposed the operator to the risk of more severe injury if an accident occurred while the tractor was being used or operated in the usual way.
60 In my opinion, the appellant's injury can and should be characterised as having been caused by the fault of the owner in the use or operation of the vehicle. The appellant's fault was with respect to the use of the tractor at the particular time and place of the injury since the instruction not to use the roll bar remained in force at the time the respondent was injured. The instruction exposed the respondent, as the operator of the tractor, to a greater risk of injury in the course of the ordinary use and operation of the tractor. While the instruction did not cause the accident, it caused the operator to suffer serious injuries in consequence of his use and operation of the tractor.
61 This conclusion is consistent with the 1995 amendments having had the purpose and effect of narrowing the scope of the legislation. One of the decisions which prompted the amendments was NRMA Insurance Ltd v NSW Grain Corporation (1995) 22 MVR 317. There the plaintiff was injured in the course of his employment while unloading a grain silo from a trailer attached to a truck. The elevator toppled from the bucket of a bobcat being used to pull the elevator off the rear of the trailer. Clarke JA (with whom Priestley and Powell JJA agreed) held that the causative fault was "in the use or operation of the vehicle [the trailer]". In his Honour's opinion, it was enough that the carriage of goods was a use of the trailer and that the loading and unloading of the trailer was incidental to that use (at 321).
62 In view of the decision in GLG, NRMA v Grain Corporation would now be decided differently. The employer was not at fault with respect to the actual use or operation of the trailer. The fault lay in the defective system for unloading the silo. The trailer happened to be involved in the process, since it had been used as the means of transport of the silo. But the ordinary use of the trailer of itself created no particular hazard for the plaintiff. The employer's fault was not "in the use or operation of the vehicle" as that expression was construed in GLG.
63 In Mercantile Mutual Insurance (Aust) Ltd v Moulding (1995) 22 MVR 325, the plaintiff was seriously injured when a rifle discharged in the cabin of her employer's utility and she was hit by a bullet. The plaintiff had been loading a lamb into the cabin of the utility at her employer's direction. The employer had left a loaded rifle in the cabin and neglected to warn the plaintiff of the danger. For much the same reasons as NRMA v Grain Corporation would now be decided differently, so Moulding would now be decided differently.
64 In my view, the appeal should be dismissed, with costs.
