50 In Walsh v Whiteley (1888) 21 QBD 371, Lindley and Lopes LJJ said at 378:
"Reading those sections and subsections together we think there must be a defect implying negligence in the employer. The negligence of the employer appears to be a necessary element without which the workman is not to be entitled to any compensation or remedy. It must be a defect in the condition of the machine, having regard to the use to which it is to be applied or to the mode to which it is to be used. It may be a defect either in the original construction of the machine, or a defect arising from its not being kept up to the mark, but it is essential that there should be evidence of negligence of the employer or some person in his service entrusted with the duty of seeing that the machine is in proper condition. It must be a defect in the original construction or subsequent condition of the machine rendering it unfit for the purposes to which it is applied when used with reasonable care and caution, and a defect arising from a negligence of the employer."
51 This passage was adopted and applied by the High Court in Metcalf v The Great Boulder Proprietary Gold Mines Ltd (1906) 3 CLR 543, to which I will further refer below.
52 In James Nimmo & Co (supra), Lord Atkinson referred to Walsh v Whiteley at 606:
"This judgment supports completely my contention that it is the use to which a thing is intended to be put and is being put which must be considered when the question whether or not there is a defect in its condition has to be determined."
53 A number of cases suggest that the absence of appropriate provision for the safety of workers was, of itself, a defect.
54 In Morgan v Hutchins (1890) 59 LJQB 197 a machine worked perfectly, save that it had an unguarded side wheel and cogs. Noting that "without labour it is useless as a machine", Lord Esher considered its "condition … that the workman cannot do his part with safety … is … a defect in the condition of a machine the working of which is a necessary performance" (at 198-199).
55 Similarly in Tate v Latham & Son [1897] 1 QB 502, a guard had been removed from a saw bench. Bruce J, adopting at 506, a definition of "defect" as "a lack or absence of something essential to completeness", concluded that some form of guard was "necessary to the completeness" of a saw bench. This conclusion was supported on appeal by Lord Esher MR and Chitty LJ at 509 and 510.
56 In Walsh v Whiteley, the majority held that there was no defect because if the machine had been used with "proper care and caution" the accident would not have happened. Lord Esher MR, dissenting said at 377:
"It has been argued that there is no defect in the condition of the machine, if it is fit for the purpose for which it is employed - that is to say, that, if it is fit for the purpose for which it is employed, it is not defective within the meaning of the Act though it is dangerous to the workman using it. Remembering that this is a statute passed to extend the liability of the employer in favour of workmen and for their greater safety, I do not think that, in considering what is a defective machine, we can confine that consideration to the question of the purpose for which it is used. The defect not applied to by the Act is not in my opinion a defect with reference to the purpose for which a machine is employed, but a defect with reference to the safety of the workmen using it: then that defect may be either in the original construction of the machine or in the use to which the machine is put."
57 In the subsequent decision of Morgan v Hutchins (supra), Lord Esher MR said at 199:
"In Walsh v Whiteley I think it was assumed by the whole Court that if the machinery were dangerous to a workman without any fault of his own, it came within the Act. The only doubt that existed in the minds of the two members of the Court was whether the defect had arisen from the negligence of the employer."
58 His Lordship distinguished Walsh v Whiteley on the basis, in effect, that it was concerned with s2(1) (i.e. Was there negligence?), rather than with s1(1) (i.e. Was there a defect?).
59 This line of authority was considered by the High Court in Metcalf v The Great Boulder Proprietary Gold Mines Ltd (supra). The Employers' Liability Act 1894 (WA) provided in s3 a right of compensation in certain circumstances including:
"Where … personal injury is caused to a workman … by reason of any defect in the condition of the ways, works, machinery, or plant connected with or used in the business of the employer … ."
60 In that case the injury occurred in the following way. An employee was descending in a cage to a mine. The cage was used both for transport of employees and for the lifting of ore to the surface. When used for the latter purpose it was the practice to let down certain supports, referred to as "chairs", at any level of the mine at which minerals were being extracted. The effect of letting down chairs was to form a fixed bed for the cage to rest upon, instead of remaining suspended from the rope. After minerals had been extracted it was the practice to lift the chairs so that the shaft was left free for the cage descending to a lower level of subsequent occasion. The injury was caused by the fact that on this occasion the chairs had not been lifted, so that as the employee was descending in the shaft, the cage collided with the chairs.
61 Griffiths CJ, with whom Barton J agreed, said at 550:
"It was not seriously disputed that a shaft is a 'way' within the meaning of the Act, but it was contended for the respondents that the term 'defect in the condition' imports something wrong in the appliances themselves, and does not cover the case of a negligent use of a properly-constructed appliance. On the other hand it was contended that, when a way - in this case a shaft - is obstructed by an obstacle, which prevents the passage of a cage to a particular part of it, this is a defect in the condition of the shaft, regarded as a way or means of approach to that part. It is not suggested that there was any defect in the condition of the shaft, qua shaft or, in the chairs, qua chairs, or that the chairs were not proper appliances to be used for the purpose already explained. The alleged defect, therefore, consists in the accidental leaving of the chairs lowered instead of raised."
62 Griffiths CJ referred to Walsh v Whiteley (supra) at 378 per Lopes and Lindley LJJ. The Chief Justice adopted their Lordships' formulation and applied it to the facts of the case before the High Court, concluding at 552:
" …the term 'defect in condition' means a defect in original construction or subsequent condition, rendering the appliance unfit for the purpose to which it is applied, when used with reasonable care and caution."
63 His Honour's reference to "subsequent condition" in addition to "original construction" recognises the possibility of a defect emerging e.g. by reason of inadequate maintenance.
64 Griffiths CJ referred to the judgment in Willetts v Watt & Co [1892] 2 QB 92 where Lord Esher MR at 98 and Fry LJ at 100 and 101 distinguished between a "defect" in the "way" and "negligent user". Subsequently, the House of Lords has doubted this distinction. In John Nimmo & Co (supra) Lord Atkinson described the distinction as "rather peculiar" (at 605). (See also at 623 per Lord Dunedin.) Griffiths CJ did not apply this distinction in terms in Metcalf. The operative part of his Honour's reasons was to the effect that the failure to raise the chairs, did not render the cage "unfit for the purpose for which it was applied when used with reasonable care and caution".
65 O'Connor J came to the same conclusion as Griffith CJ. His Honour said at 556 that the shaft in the mine:
" … was without defect; it was properly equipped; the cage and other apparatus for carrying them in were properly appointed and furnished with all necessary appliances for carrying the men safely; the system of working the way was not complained of. But the way, the cage, the signals, and other appliances no matter how perfect in themselves, must be worked with reasonable care, otherwise accidents are very likely to happen. Where the injury complained of has been caused to a workman by the negligent working of a 'way', cage, signals, or other appliances, in themselves without defect, and the negligence was that of a fellow-servant, not within the class of persons for whose negligence the Act has made the employer liable, the plaintiff cannot succeed."
66 As these authorities suggest, fine issues of characterisation can arise in the application of the appropriate test to particular facts. The distinction between a "defect" and "negligent user" may not always prove helpful, as many sets of facts are capable of being characterised in both ways. The issue is unlikely to arise often under the Act, because one of the other sub-paragraphs of the definition of injury is likely to be applicable in the case of "negligent user".
67 The emphasis given by the High Court in Metcalf, and in the English authorities, to the fitness for the use to which the machinery etc is intended to be put is, in my opinion, an appropriate perspective from which to approach the question of a "defect in the vehicle" for the purposes of the Motor Accidents Act. The statutory context, like that of the English Employers' Liability Acts, is compensation for personal injury arising from the fault of a person in control of the circumstances in which machinery is operated.
68 The defect must be "in" the vehicle. A vehicle is not "defective" only because its operation in a particular manner may lead to injury. However, the manner in which it is intended to operate may determine whether there is a "defect" "in" the vehicle.
69 In the present case, the Respondent submitted that the absence of any form of hydraulic or mechanical assistant for lifting was a "defect" for purposes of the Act. The Appellant emphasised the possibility of a team lift as a safe system of work for the trailer in its extant condition. In the circumstances of the present case, the Appellant's characterisation should be rejected.
70 I have concluded above that the design of the trailer was such that it was intended to be used in circumstances where a single worker lifted each ramp. When this happened it was, in my opinion, the use or operation a vehicle in which there was a "defect" for its intended use. It was not negligent use of a vehicle otherwise fit for the purpose or use to which it was intended to be put.
71 The Appellant's submissions on these grounds should be rejected.
