COMMON LAW DIVISION
HARRISON J
5 March 2009
20238/06 Glen Stuart Middleton v Alan John Erwin & Iveco Trucks Australia Limited
JUDGMENT
1 HIS HONOUR: On 21 November 2002 the plaintiff was severely
injured driving to work when an International Transtar F4670 prime mover and
semi-trailer
("the truck") driven by the first defendant collided with his car
on the Bogan Road near Parkes. The truck was travelling in the
opposite
direction and crossed onto the incorrect side of the road. The accident was
caused by a failure of the steering mechanism
in the truck, which was
manufactured by the second defendant. Damages were agreed on the first day of
the hearing. The issues remaining
for determination are therefore now limited
to the question of the defendants' liability (if any) to the plaintiff and to
resolution
of cross claims filed by each of the defendants against the
other.
2 The plaintiff alleges that the first defendant failed properly to
service or maintain the truck. In particular, the plaintiff alleges
that the
first defendant failed to maintain the steering mechanism and other associated
mechanical parts or to inspect them in a
way that would and should have revealed
whether or not a clamping bolt in a universal joint had been adjusted to a
torque setting
that would have prevented an intermediate shaft from becoming
detached from the joint leading to a loss of control. This is necessarily
explained and considered in more detail later in these reasons. Although the
claim against the first defendant as originally pleaded
included allegations
relating to the way in which he drove, managed and controlled his truck, these
were abandoned at the trial (if
not well before) in deference to an
uncontroversial recognition that the collision was caused by mechanical failure
unrelated to
any aspect of his driving.
3 The plaintiff alleges that the second defendant manufactured the truck
with design defects in the steering mechanism that rendered
it liable to become
disengaged either as the result of a loose universal joint clamping bolt or
loose bearing grub screws or both.
There was no claim that it was constructed
or assembled poorly, as opposed to complaints about its design. This is also
necessarily
explained and considered in more detail later in these reasons. The
plaintiff alleges in addition that the second defendant failed
to produce and
supply an owner's or operator's manual or handbook for the truck that specified
that regular inspection and/or maintenance
of the steering mechanism and/or all
steering linkages was required. A claim relying upon s 75AD of the Trade
Practices Act 1974 was abandoned.
4 By his amended first cross claim the first defendant claims
contribution from the second defendant alleging that it was negligent
in the
same respects pleaded by the plaintiff against him. The first defendant also
relies upon s 74AD and s 74AE of the Trade Practices Act 1974.
There is in effect a corresponding claim by the second defendant against the
first defendant in the third cross claim with the exception
of the statutory
counts. These cross claims are referred to below.
The steering system and the mechanism of its failure
5 It is essential at an early stage to understand the steering mechanism
of the first defendant's truck and the particular parts of
it that are said to
be inculpated in the ultimate failure that resulted in the complete loss of
control that he experienced immediately
before the collision. Potentially two
portions of the truck's steering system are involved. The first is a universal
joint connecting
the intermediate shaft to the upper steering column. The
second is a seized bearing in a flangette housed on the engine side of
the
firewall, in conjunction with the absence or inappropriate adjustment of grub
screws intended to attach the intermediate shaft
to the inner surface of the
bearing. These are described in turn.
6 First, there was agreement among the experts that the likely sequence
of events that led to the loss of steering included the disengagement
of a
clamped connection between the universal joint connecting what is known as the
intermediate shaft and the upper shaft of the
steering system. This universal
joint was located within the cabin of the truck encased in a removable housing
attached by six screws.
It was situated immediately below the steering wheel in
a position between the driver's legs.
7 The universal joint comprised two yokes connected by a central spider.
The end of each yoke consisted of a split, splined housing
designed to
accommodate a splined shaft. This was, in lay terms, a circular opening into
which the splined end of the intermediate
shaft was inserted. The splines on
the shaft mated with the splines in the opening. The shaft was fixed into the
universal joint
by inserting the matching splined splint housing of the yoke and
placing a pinch bolt (sometimes called a clamp bolt or clamping
bolt) into a
clearance hole in the joint so that the bolt intruded into the groove of the
splined shaft. The bolt was secured in
place by means of a nut. The bolt
passing through the hole to a corresponding hole on the opposite side was to be
tightened to a
specified torque of between 45Nm to 50Nm. In that configuration
the shaft was secured in its position within the universal joint
by mechanical
force exerted upon the joint by the tightened bolt and the marrying of splines
on the end of the intermediate shaft
with corresponding grooves upon the inner
surface of the opening in the universal joint.
8 Prior to the collision the locking of the splined shaft into the
universal joint had been compromised by progressive loss of the
bolt volume due
to wear of that part of the bolt within the groove. Some localised wear of the
splined shaft was also evident, particularly
in the section of the groove and
the adjacent splines closer to the end of the shaft. The wear would appear to
have occurred concurrently
on both the bolt and the shaft and the wear was
predominantly asymmetrical. The worn section of the bolt used to secure the
spline
of the steering shaft to the lower yoke of the universal joint was
grooved in a pattern consistent with the contours of the splined
shaft.
Eventually the bolt became ineffective in locking the shaft and the assembly,
consisting of the universal joint, the steering
column and the steering wheel
separated from the splined shaft.
9 The attachment of the upper yoke of the universal joint to the steering
column was achieved in the same way. A short splined section
20mm long of a
25mm diameter shaft at the base of the steering column allowed connection to the
universal joint. This shaft was
also grooved circumferentially to allow a pinch
bolt connection to the joint. Although on examination this joint was still
intact,
axial sliding could be effected over a distance of about 2mm, indicating
that the securing bolt was not producing a snug fit in the
groove of the splined
shaft. Inspection of this bolt showed that wear had commenced in the region
contacting the surface of the
groove in the splined shaft and that it also
contained wear grooves parallel to the splines that had been produced by
relative motion
between the bolt and the shaft. Some wear of the splined shaft
was also evident. One of the experts described the condition of
this bolt as in
effect a "snapshot" of the condition of the failed bolt from the joint of the
lower yoke at an earlier state of wear.
10 In the present case the vibration or slip was axially directed because
the mating of the splines in the universal joint with the
splines in the shaft
prevented relative rotation. That is confirmed by the axial wear pattern on the
bolts that corresponded to
the shape of the contours of the upper and lower
splined shafts.
11 Fretting wear was the main mechanism of failure. The essential
feature of fretting is the presence of small amplitude vibrations
in a nominally
stationary joint. The upper and lower universal joints that respectively
connected the steering column assembly and
the splined steering shaft to the
yokes of the universal joint were subject to vibratory forces during normal use
of the truck by
transmission from the engine and the wheels. Slip or relative
motion between the mating surfaces resulted in adhesive wear due to
micro
welding and fractures of asperities on the surfaces of the mating steel
components. As wear progressed, the amplitude of the
movement also increased,
producing significant slackness in the joint. In addition to increased sliding
contact, impact loading
of the joint components is also likely to have occurred.
This would have increased the rates of wear caused by both adhesion and
abrasion. The key cause of the failure in the present case was the relative
motion between the bolt and the splined shaft. Professor
Dunne originally
opined that the possible reasons for this included poor fit of the mating
components and insufficient tightening
("torquing") of the locking or pinch
bolt. He appears to have resiled from the former contention during
cross-examination. The
second contention was accepted by all of the
experts.
12 Secondly, the intermediate shaft of the steering mechanism passes
through the firewall of the cabin of the truck and into the engine
bay via a
housing for a flangette and its fitted bearing. The shaft is secured or located
axially to the bearing by two grub screws,
so that they rotate together when
turned. When examined following the collision at least one of the grub screws
was found to be
missing and the other was partially unscrewed and, according to
one expert account, buried in a hard mixture of grease and dirt.
The bearing
itself was found to have seized. There were witness marks scored into the
intermediate shaft at this location suggesting
or demonstrating that the shaft
had rotated within the bearing, instead of with it, and that this had been
caused by the missing
or ill-adjusted grub screws, which were not operating to
locate it to the shaft. Rotation of the shaft in this way, unlocated to
the
bearing, therefore continued to occur notwithstanding that the bearing had
seized. But for this behaviour, steering of the truck
in any way at all would
have been wholly prevented or at least significantly inhibited.
13 A conclave of experts on 29 January 2009 produced answers to a series
of questions that included the question, "What [was] the
likely cause as to the
collapse of the steering column?" The answer given by the experts was in the
following terms:
"1. The disengagement of the universal joint from the intermediate shaft was caused by gross fretting under the effects of normal operational vibration over a long period.
2. This fretting was caused by road and engine vibrations in conjunction with the following conditions:
(a) the bolt, which is intended to provide the clamping force to secure the splined connection, being or becoming loose;
(b) the axial support for the lower end of the intermediate shaft being rendered ineffective (allowing the shaft to slide axially within the bearing) in that:
(i) the bearing at this point was seized; and
(ii) of the two grub screws intended to clamp the shaft to the bearing, one was missing and the other not tightened; and
(c) the combined weights of both the intermediate shaft and the lower shaft thus producing a significant axial load at the splined connection."
14 Mr Colin Simpson,
one of the four experts, was unsure whether or not the disconnection of the
universal joint required the grub
screws to be missing or loose. Consideration
of this opinion is important in a determination of what, if any, role was
ultimately
played by the seized bearing in the steering failure. This is
discussed in more detail below.
Background
15 Whereas the physical cause of the steering failure appears relevantly
to be uncontroversial, the legal responsibility for it remained
at all times
significantly in dispute. Assessment of that issue requires some review of the
background and circumstances leading
up to the accident.
16 The first defendant picked up a delivery of grain on the day of the
accident at a silo about five to six kilometres from where
the collision
occurred, having driven there from Parkes at about 6.30am that morning. He had
no indication in that 40 minute journey
that there was anything wrong with the
steering. Indeed, it was his evidence that he had never experienced any
problems with the
steering before this day. At a point approximately one
kilometre from the Newell Highway on the intended journey back to Furney's
Flour
Mill at Dubbo, while travelling up a slight gradient, the steering of the truck
"went light and the truck yielded right".
The first defendant said that he had
no control and no steering and that the truck was totally non-responsive. The
truck went right
and onto the opposite side of the road that happened to curve
to the left at that point as well. The truck was travelling at between
90 and
95 km/h. The first defendant put his foot on the brakes as hard as he could and
applied the trailer brake with his right
hand. The collision with the
plaintiff's Holden sedan occurred within a second or so thereafter. A series of
photographs that are
in evidence depict the scene of the collision and its
aftermath in graphic detail that is not in dispute.
17 The first defendant had owned the truck since April 1999 when he
purchased it from Australian Used Truck Centre in Lavington, a
suburb of Albury.
The vehicle did not come with an operator's manual when he purchased it.
Repairs, maintenance and service to the
truck was a combination of work that the
first defendant performed himself and work performed by mechanics that he
employed. The
first defendant did not have formal training as a motor mechanic
but had learned about the repair and maintenance of vehicles as
he grew up on
the family farm. He had worked on tractors, old truck and utes. He conceded
that during his time on the farm he "learnt
quite a lot about vehicles" and
about maintaining and repairing them. He replaced the engine in the truck over
a period of a month
to six weeks at a workshop in town in 2001. He said that he
"just followed the book" and asked a mechanic for help if he ran into
trouble.
18 The RTA inspected the truck annually for registration purposes. The
steering mechanism of the truck was "off limits" to the first
defendant in terms
of any work that was carried out upon it by him. He told police in a record of
interview given following the
accident that he shied away from "anything
normally to do with the steering" as he did not know enough about it. He
produced a bundle
of documents in his possession in response to a subpoena that
consisted of records of work performed on the truck on his behalf during
the
time that he owned it. The documents were not a complete record of all work
that was done by others and did not take account
of work performed by him. The
first defendant said that at no time did he ever ask any of the people who
looked at the truck, either
to service it or to carry out work upon it, to
inspect the universal joint linking the top shaft with the intermediate shaft in
the
steering mechanism. He travelled somewhere between 120,000 and 150,000
kilometres every year.
19 Mr Wheelahan of Queen's Counsel who, with Mr A R G Johnson of counsel,
appeared for the plaintiff, cross-examined the first defendant
about his
understanding of the steering mechanism at the time of the collision. This
evidence was as follows:
"Q. Well, what do you say? Did the steering mechanism stay connected as far as you were aware or was there an actual detachment?A. The first I knew of the part coming off was when Mark Smith had a look underneath it, after the accident.
Q. Was that at the scene of the accident?
A. Yes.
Q. So within a relatively short time you were aware that the steering mechanism, rather than being attached to the steering wheel was at your feet in the cabin or where your feet would have been?
A. Yeah.
Q. Now, you understood then, that is at the time that this accident happened, that is after the accident happened, the mechanism involved didn't you?
A. The universal?
Q. Yes?
A. Yeah, that it fell off, yeah.
Q. And that you knew the means whereby the retaining bolt passed through the apertures in the universal and the groove at the splined end of the intermediate shaft?
A. Yeah.
Q. And that it was retained in that fashion within the universal joint?
A. Yep.
Q. And I take it that you knew that if there was any lack of integrity in that system that is where the bolt retained the splined end of the intermediate shaft, that there could be a failure in the steering operation?
A. I don't understand what you mean. Like, if the bolt's come past the groove are you saying?
Q. No. I'm suggesting to you that you were aware at the time this accident happened that if the bolt did not retain the intermediate splined shaft within the universal joint, that the steering mechanism could fail?
A. Well, I suppose that's right, yeah.
Q. And if it was the wrong sized bolt, that that problem might occur?
A. I suppose it would if it was the wrong sized bolt.
Q. Or I think you said when asked, "If it is allowed to jiggle past the groove and come off, I don't know", you were talking about it falling off?
A. Well, I'm only going on what they told me.
Q. I'm suggesting to you that that is what you understood at the time of the accident?
A. Yeah."
20 The first defendant was also
cross-examined on evidence that he gave to the effect that he greased a nipple
that he thought was
located on the flangette housing a bearing on the engine
side of the firewall through which the intermediate shaft passed. This
is what
he said:
"Q. You weren't in any doubt when you gave that evidence that you were greasing the bearing, were you?A. Greasing the grease nipple which I assume is what I was greasing but it is not. It is the shaft up above.
Q. I'm sorry, I can't hear that, Mr Erwin?
A. Greased the grease nipple, yes.
Q. If I heard you correctly the evidence that you gave was this, and I'm suggesting this is verbatim the words that you used, "I greased a nipple point on the bearing". Do you recall giving that evidence?
A. On the bearing?
Q. Your evidence was, I suggest to you, that you greased the nipple point on the bearing?
A. Well--
Q. No, no, no. Was that the evidence you gave?
A. If you have got it there I suppose that is what I said.
Q. Let us just not accept what I may have written down, Mr Erwin. I'm asking you, is that what you said?
A. Yes.
Q. And you agree with me, do you not, that there is no nipple point on the bearing?
A. Yes.
Q. If you did grease the bearing and there was no nipple point I suggest to you that you were greasing it for a purpose unconnected with any nipple point. What do you say to that?
A. Well, what I thought I was greasing was the bearing but it is not, it's the shaft up top, the throttle linkage. I just got it mixed up.
Q. So when you said that you greased the nipple point on the bearing you now say that that evidence wasn't correct, is that right?
A. Well, it can't be. There is no grease nipple there.
Q. Unless you were greasing the bearing for an entirely different purpose, namely to allow the intermediate shaft to rotate within--
A. No.
Q. - the bearing?
A. No.
Q. You see, that would explain why you would grease the bearing if there was no nipple point there?
A. The reason I said I thought I was greasing the bearing is because there was a grease nipple up there and that is what I thought I was greasing. "
21 It was put to the first defendant that he
knew before the accident that the bearing in the flangette had seized and that
he had
loosened a series of two grub screws that were located on the bearing,
which kept it fixed or located to the intermediate shaft,
in order that the
shaft could continue to rotate within the bearing despite the fact that it had
seized. He denied all of these
suggestions. The first defendant said that he
had never observed before the accident whether or not there was a grub screw
absent
from that bearing. He agreed with the obvious proposition that if the
bearing had seized and the grub screws were tightened upon
the intermediate
shaft, the steering "would be extremely difficult to manipulate". He denied
that he had greased the bearing in
effect to facilitate the operation of the
steering after the bearing had seized and the grub screws had been loosened for
the purpose
of permitting him to continue to drive the truck. It is fair to
observe that the first defendant consistently denied that he had
released the
grub screws or oiled the bearing.
22 The first defendant never arranged for anyone else to carry out
maintenance upon the steering system. He said, "No, there was
no need to. To
the best of my knowledge it was working all right". He gave the following
evidence:
"Q. And in the whole of the time that you had it, as far as you know, no one even looked at the steering mechanism in this truck?A. Not unless the RTA did, no.
Q. Well you see, the RTA doesn't do the maintenance on your vehicle, does it?
A. No.
Q. And you do?
A. Yes.
Q. And you are responsible for it, correct?
A. For the part that I do, yes.
Q. And play, I suggest to you, any part that you leave undone, you are responsible for that as well, aren't you, well you know, you have to know it is undone?
A. Mm mm.
Q. You see if you don't do anything, you must agree that you would be responsible if there was a failure associated with your lack of direction or instructions to maintain, would you not?
A. I suppose.
Q. You can't just leave it undone and then say well it wasn't done therefore I am not responsible, can you?
A. I suppose not. "
23 In cross-examination by
Mr R A Cavanagh of counsel, who appeared for the second defendant, the first
defendant also gave the following
evidence:
"Q. Now, you say, do you then, that you relied on the RTA to carry out an inspection every year?A. That is mandatory.
Q. Is that right?
A. Yes.
Q. But you did not organise or ask any of the service people who had carried out some form of servicing to inspect the steering shaft assembly during your period of ownership?
A. No. "
24 The first defendant had never seen
an operator's manual for his truck. He did however purchase a workshop manual
in order to rebuild
the engine when it required rebuilding in about June 2001,
as referred to earlier. He confirmed that he had never asked a service
mechanic
to even look at the truck's steering mechanism. He attended to the "routine
maintenance of just about everything else on
[the] vehicle other than the
steering". He agreed that between the date that he purchased the truck and
November 2002 he did "not
undertake one element of preventive [sic] maintenance
in relation to the steering".
The plaintiff's case against the first defendant
25 Mr Bartlett of senior counsel who, with Mr J V Gooley of counsel,
appeared for the first defendant conceded during the course of
the trial that
the first defendant was in breach of his duty of care to the plaintiff in
failing to maintain the steering mechanism
of the truck in the ways alleged by
the plaintiff. This was in my opinion an uncontroversial concession. It
requires no present
elaboration. However, for the sake of clarity, Mr Lewis, a
former owner and operator of the truck, gave evidence that he engaged
Corowa
Truck and Trailer Pty Ltd to carry out a full service on it every month and/or
20,000 to 25,000 kilometres. He said that
full services were carried out on the
truck with that regularity throughout the period of his ownership. He said it
was his routine
to do services monthly as that was "determined by [him] as a
matter of good practice". He also said that he was a strong believer
in the
concept of preventative maintenance rather than breakdown maintenance. He said
that when routine services were carried out
he would expect his service provider
to ensure that all operational aspects of the truck were checked thoroughly. In
addition, one
of the experts, Mr Anderson, said that he would expect "a planned
maintenance schedule . . . to include a thorough inspection by
an experienced
technician at the 26,000 kilometre intervals with more detailed inspections
annually, giving many opportunities for
the impending failure to be identified
and corrected". This is in stark contrast to the approach taken by the first
defendant.
26 The first defendant contended, however, that the plaintiff had failed
to establish a causal connection between that admitted breach
and the failure of
the steering mechanism. In this respect it is to be observed that the plaintiff
has both a legal and evidentiary
onus of establishing causation: see
Flounders v Millar [2007] NSWCA 238; (2007) 49 MVR 53.
27 The plaintiff's case against the first defendant can conveniently be
formulated as an inquiry whether any system of maintenance
and inspection that
the first defendant should have carried out would have revealed the incipient
problem with the pinch bolt in
the universal joint that has been identified by
the experts as the cause of the failure. It was the plaintiff's case that the
accident
occurred because the nut on the pinch bolt was loose and that this led
to the abrasive and adhesive wear that caused the intermediate
shaft to drop out
of the joint. The plaintiff contended that a proper inspection of the universal
joint would have revealed whether
or not the nut on the pinch bolt was loose.
He relied upon the following evidence given concurrently by experts at the
trial:
"WHEELAHAN: Gentlemen, the axial progression of the intermediate shaft as it begins its disengagement from the universal joint as two elements, firstly at the universal joint the spline, I think you Dr Casey indicated would begin to appear?
WITNESS CASEY: Mr Anderson indicated that, but yes I agree.
WHEELAHAN: I will take you to the other end, you said that the polishing would begin to appear?
WITNESS CASEY: Yes.
WHEELAHAN: With this process where the universal joint is progressively releasing its grip on the bolt, the pinch bolt, what period of time are we looking at as this extrusion or axial play develops, is it a catastrophic event that occurs the minute before the accident, or something else, Mr Anderson?
WITNESS ANDERSON: That progressive decay would in my opinion take years rather than months or weeks.
WHEELAHAN: Dr Casey?
WITNESS CASEY: I agree.
WITNESS DUNNE: I agree.
WITNESS SIMPSON: I agree.
WHEELAHAN: So as the spline slowly begins to appear at the top and such polishing as is visible begins to appear at the bottom, inspection over years would reveal one or other or both of those phenomena, correct?
(All witnesses replied yes.)
WHEELAHAN: I think you all agreed that visual inspection, before there was other evidence, either the appearing spline or polishing marks would be unlikely to reveal the fact that the tension bolt, the clamp bolt was releasing its grip on the intermediate shaft, correct?
(All witnesses replied yes.)
WHEELAHAN: You all agreed a simple manual activation of the components would also be unlikely to reveal what was occurring within the system.
(All witness replied yes.)
WHEELAHAN: What then would you propose as the answer to discovering that problem, Mr Anderson?
WITNESS ANDERSON: That would require a periodic application of a spanner.
WHEELAHAN: Routine maintenance?
WITNESS ANDERSON: Yes.
WHEELAHAN: Preventative maintenance?
WITNESS ANDERSON: Yes.
WHEELAHAN: Dr Casey?
WITNESS CASEY: Yes.
WHEELAHAN: Professor Dunne?
WITNESS DUNNE: Yes.
WHEELAHAN: Mr Simpson?
WITNESS SIMPSON: Yes."
28 The first defendant
submitted that even though the experts all agreed following the conclave that
regular inspection and maintenance
of the steering, including the whole of the
steering column, was required, there was no evidence from a suitably trained or
experienced
source, such as an Iveco dealer or service centre, or even a truck
mechanic, about just what preventative maintenance, of the type
for which the
plaintiff contends, would have taken place, had the vehicle been sent for
service, in the absence of a specific complaint
about a particular problem with
the steering. However, there are at least two responses to this
proposition.
29 First, the conclave was asked and answered "yes" to questions 7(a) and
8, which were respectively in the following terms:
"7. (a) Should the subject universal joint as designed and provided in the vehicle as manufactured be the subject of regular maintenance to check for axial play or to periodically re-tighten or replace the high tensile bolts?"
"8. Was regular inspection and/or maintenance of the steering (including the whole of the steering column) required given the nature of the materials used, the design and the magnitude of the consequences of a steering failure?"
30 It does not appear to me that the
answers to those questions taken alone or together are susceptible to the
limitation or qualification
for which the first defendant argues. Indeed, the
experts' opinion that regular maintenance to check for axial play was necessary
appears to foreclose upon the suggestion that only a service or inspection
occurring in response to a specific complaint would have
detected the problem.
The very problem was slow but progressive axial movement of the intermediate
shaft from its designed location
within the opening in the universal joint.
That is what should have been looked for and that is what should have been
detected.
31 Secondly, the Operator's Manual for the truck contained a section
dealing with steering. That section is in the following terms:
"STEERING
Be alert to any change of feel in steering when driving. For example increased steering effort, unusual sounds when turning, excessive wheel play, change in normal position of steering wheel when driving in straight ahead, vehicle pulling to either side, increased feed back of road shocks to steering wheel.
These unusual movements in steering signal the need to stop for immediate inspection. Check the rod and drag link end clamp bolts, they must be tight. Ask your service mechanic to examine steering mechanisms. Minor adjustments could head of [sic] further problems.
Check front spring for possible main leaf fracture at eye. Check power steering system for leaks or hose chafing, repair at once. Maintain proper steering gear and power steering pump lubricant levels. Regularly inspect all steering linkages particularly for body to chassis clearance.
The power steering system is designed to absorb road shocks transmitted from road wheels. However, if under high speed operations in adverse road conditions (large pot holes, broken road edges etc.) significant feed back (steering wheel kick) is felt at steering wheel, it is recommended to reduce speed immediately. The high road shocks transmitted at these speeds could cause damage to steering system." (Emphasis added)
32 The
first defendant sought to argue that these words did not contain a general
instruction to inspect the truck's steering but
were words specifying the need
to do so only in certain circumstances. He contended that the upper universal
joint was not nominated
as a lubrication part and was in any event enclosed
within its cover inside the cabin so that, absent a complaint that would draw
it
to the attention of a servicing mechanic, it would in all likelihood remain
unobserved and untouched. Moreover, the first defendant
submitted that the
plaintiff had not established that the extent of any inspection that might have
occurred would have gone beyond
merely visual examination, which would not
reveal axial slip of the intermediate shaft. The first defendant submitted that
there
is no evidence of any protocol that would have required inspection of the
universal joint in the absence of complaint of problems
or obvious defect that
would lead the inspecting mechanic to test the torque of the pinch bolt nuts
using a spanner as described
by the experts. Mr Simpson, in his report dated 27
June 2007 suggested that factory maintenance through International Dealers would
not have included "the relevant universal joint clamping mechanisms". In brief,
the first defendant submitted that no inspections
would have been carried out in
the absence of a specific complaint and that even if the nominated or
recommended inspections had
been carried out they would not have revealed the
problem.
33 The emphasised words in the extract from the Operator's Manual seem to
me to be clear and unambiguous. There is little, if any,
scope for doubt about
the meaning of the words "regularly inspect all steering linkages". The truck
had travelled over 1,000,000
kilometres when the first defendant acquired it and
he drove it at least 500,000 kilometres and possibly more. The conditions
encountered
by the truck when driven by him as a grain haulier on country roads
and properties in rural Australia would undoubtedly have included
the road
conditions of the type to which the manual draws specific attention. Service
and maintenance of the truck in these circumstances
if properly carried out
would in my opinion have extended to checking the status of the pinch bolts in
the steering column universal
joints. Such an inspection by a competent
technician would have revealed that the pinch bolt was wearing and that there
was progressive
axial slip of the intermediate shaft. Recognition of this
condition at an appropriate stage would have led to suitable adjustment
or
repair that would have avoided the collapse. Mr Simpson's opinion in his 27
June 2007 report was maintained by him in contrast
to the opinion expressed by
the other experts following the conclave: see question 5(b)(i) where the others
were of the opinion that
the failure to maintain the clamping bolts at an
adequate torque setting was contributed to by the first defendant's failure to
implement
a suitable maintenance regime.
34 The plaintiff also contended that there was a failure by the first
defendant to inspect and maintain the bearing that housed the
steering column.
As discussed earlier, this was located in the flangette bolted to, or near, the
firewall in the engine bay. A
failure of the universal joint would leave the
intermediate shaft unrestrained unless grub screws locating the shaft to the
bearing
were in position and properly adjusted. The plaintiff alleged in effect
that the first defendant either did not do this or took
no steps to ascertain
the true position. This is a curious aspect of the case against the first
defendant that requires some explanation
before proceeding further.
35 Mr Simpson was alone in expressing some doubt that the grub screws
locating the intermediate shaft to the inner circumference of
the bearing would
have been capable of restraining the axial collapse of the intermediate shaft
following failure of the universal
joint. He was said to be "unsure as to
whether or not the disconnection of the universal joint require[d] missing or
loose grub
screws". The first defendant's acceptance that he had breached his
duty to maintain the truck properly did not appear to extend
to an acceptance
that he failed to ensure that the grub screws in the bearing were present and
adjusted to locate the shaft to the
bearing, as it should have been. In this
respect it is instructive to review two other answers given by the experts to
questions
posed for their consideration in the conclave. The experts all
answered "yes" to the following questions:
"5 As at the time of the accident and the period leading up to it is it probable that:
(a) The universal joint clamping bolts were not maintained at an adequate torque setting and that, had they been so maintained, the collision would probably not have occurred?"
"6(a) Does the original design contain a sensitivity to a combination of a loose universal joint clamp bolt and loose bearing grub screws and that whenever this combination of conditions occurred there existed a real risk that the steering intermediate shaft may become disengaged?"
36 The first of these answers
clearly inculpates the universal joint as the cause of the steering failure
without any reservation
or qualification related to the state of the bearing or
the grub screws. The answer to the second question is no more than recognition
of the possibility that the properly adjusted grub screws might have
maintained the intermediate shaft in position so that the collapse did not
occur.
37 The first defendant was cross-examined to suggest that he either
removed or loosened the grub screws because the steering would
not operate when
the bearing seized. An associated suggestion was put to him that he oiled the
inner circumference of the bearing
to facilitate rotation of the intermediate
shaft within the bearing, rather than located to it, so that the truck could
continue
to be steered even though the bearing had seized. As already
indicated, the first defendant denied all of these suggestions.
38 However, even an acceptance of these denials does not to my mind
provide the first defendant with an argument that the accident
was causally
unconnected to his breach of duty. The first defendant submitted that there was
no evidence to suggest one way or the
other that at the time of the accident
both grub screws were present although loosened so as not to be in contact with
the intermediate
shaft. Whether there was or not seems to me to be wholly
beside the point. The fact is that the failure of the universal joint
led to
the steering collapse that resulted in the collision. The issue of what
inspection or maintenance of the bearing should have
been carried out by the
first defendant or whether any inspection would have revealed a problem is in
the first instance a matter
of no consequence in a consideration of the
plaintiff's case against the first defendant.
39 The plaintiff does not have to establish, in order to succeed, that
the first defendant was negligent in relation to the state
of the bearing and
the grub screws if the evidence otherwise reveals that for some unknown or
unestablished reason the bearing and
the grub screws were unable to prevent the
failure of the steering mechanism. The simple fact is that the state of the
bearing and
the grub screws, of which the first defendant was on his case
ignorant and for the state of which he was on his case not liable,
was such that
it facilitated the collapse of the steering mechanism following failure of the
universal joint for which he is liable.
The role played by the state of the
bearing and the grub screws and the first defendant's connection to them are
neutral events
in the plaintiff's principal claim against him. They are not
factors that permit the first defendant somehow to argue that his breach
of duty
in relation to the universal joint is causally unrelated to the accident. As
the first defendant emphasised in his written
submissions, the grub screws were
not a clamping device and there is no evidence that they were intended to
maintain the integrity
of the steering column in the event of a failure of the
universal joint.
40 The first defendant sought to argue as a secondary proposition that if
the grub screws would have prevented the collapse if properly
adjusted, he was
not in any event responsible for the fact that they were either missing or not
properly adjusted. However, this
argument does not withstand the opinion of the
experts. For example, question 10, to which the conclave also produced an
affirmative
answer, was relevantly as follows:
"10. (a) Was the bearing at the lower end steering shaft seized at and prior to the accident?
10. (b) If so, does this indicate that such part of the steering system was not properly maintained?"
41 The first answer was
never controversial. The second answer is in my opinion sufficient to dispose
of the first defendant's contention
that the problem with the bearing was
undiscoverable on inspection and that the first defendant is therefore not
responsible for
any role that it played in the accident. The fact that the
bearing had seized is not connected in any critical way to the failure
of the
steering mechanism at the universal joint pinch bolt assembly. There is, for
example, no suggestion that the seized state
of the bearing initiated or
exacerbated or contributed in any way at all to the abrasive and adhesive forces
that led to failure
of the joint. That failure occurred independently of
whether or not the intermediate shaft rotated within the inner circumference
of
the bearing in its seized condition or alternatively rotated with the bearing
located to it by the grub screws as designed.
42 However, the state of the bearing, as the experts agree, casts direct
light on the extent to which the first defendant maintained
that part of the
steering. Adequate maintenance of the bearing so that, presumably, it would not
have seized, would not have prevented
failure of the universal joint, which was
the result of the first defendant's failure to maintain it. But there was also
a failure
by or on behalf of the first defendant to appreciate that the
existence of witness marks on the lower end of the intermediate shaft
were an
indication that the bearing had seized. It bespeaks inadequate maintenance.
But in any event, even though the experts agreed
that purely visual inspection
would not have revealed whether the grub screws were loose or that the bearing
had seized, more than
visual inspection was required and might have been
anticipated as a matter of routine. Replacement of the seized bearing would
necessarily
have required that the grub screws be loosened and readjusted.
Proper inspection and maintenance going beyond mere visual inspection
should
have been effected, and not only in response to complaint about a particular
problem. (The presence of oil stains on the
bearing strongly suggests that a
problem had been encountered at some stage and "treated" in any event). That
seems to me to be
the logical and obvious conclusion from the experts' joint
opinion that that part of the steering mechanism had not been properly
maintained. There is an irreconcilable tension between the view of the experts
on the one hand and the first defendant's submission
that the problem would not
have been discovered in the normal course of routine maintenance on the other
hand.
Conclusions in relation to the first defendant
43 The first defendant was under a duty to other users of the roadway,
including the plaintiff, not to injure them through the use
of a truck with
defective steering. The first defendant was aware of the potentially
catastrophic consequences of a steering failure
in a vehicle of this type. The
first defendant breached his duty to the plaintiff in that he failed properly or
adequately, and in
some respects at all, to maintain the steering mechanism of
the truck. Proper inspection would have included inspection of the universal
joint at the upper end of the intermediate shaft and adjustment of the pinch
bolt that secured that shaft within the joint. Proper
inspection would have
revealed, at a point before it failed, that the shaft was in an incipient state
of separation from the universal
joint and would have prevented it from
occurring. The first defendant's failure to inspect and maintain that universal
joint was
the cause of the collision that injured the plaintiff.
The plaintiff's case against the second defendant
44 In formulating his case against the second defendant, the plaintiff
relied upon statements of principle such as the following from
Suosaari v
Steinhardt [1989] 2 Qd R 477 at 488-489:
"In undertaking the process of design a manufacturer is under a duty 'to design his machine so as to keep its inherent dangers to a minimum and so as to avoid the addition of further risks which [are] not inherent' (Todman v Victa Ltd [1982] VR 849 at 852 per Lush J and see to similar effect Murphy J at 857). Discharge of the duty requires the designer to think through the suitability of the design, the problems and risks associated with the design; the graver the foreseeable consequences of failure to take care, the greater the necessity for special circumspection (Independent Broadcasting Authority v EMI Electronics Ltd (1980) 14 BLR 9 (HL) at 28, 31; Winward v TVR Engineering [1986] BTLC 366 CA). The standard to be applied when one is dealing with a machine is that of a reasonably competent engineer (Winward at 5; Griffiths at 220–221). Where the risk is real, although the incidence of it may be low, the designer is under a duty to minimise the risk by taking all reasonable steps to eliminate it, particularly where the alteration to the design is simple and inexpensive (Winward at 5; Todman at 857; Wyong Shire Council at 47–48). It is not sufficient to design a product which is satisfactory merely for the purpose for which it is intended to be used (Lambert v Lastoplex Chemicals Co Ltd (1971) 25 DLR (3d) 121 at 124; Rivtow Marine Ltd v Washington Iron Works (1973) 40 DLR (3d) 530 at 543). The manufacturer is under a duty to take care to reduce the risk of injury as far as he reasonably can ... "
45 The plaintiff's case consisted in a
contention that wear in the universal joint that retained the intermediate shaft
amounted to
or was evidence of a design fault for the consequences of which the
second defendant was liable. The plaintiff did not contend that
the pinch bolt
became loose as a result of a faulty design, because when properly adjusted it
required a force of approximately one
tonne to release it and road vibrations or
other effects from normal use of the truck would be insufficient to cause this
to occur.
Nor did he contend that the bolt must have been loose when it left
the second defendant's control. However, if the bolt was not
adequately
adjusted, it could lead to wear sufficient to cause the clamping mechanism to
fail. That propensity was said to be a
function of an allegedly inadequate or
faulty design.
46 The plaintiff's case drew upon a series of answers given by the
experts following the conclave. Some of these have been referred
to already.
The following questions and answers are also relied upon by the plaintiff in
support of his case against the second
defendant:
"4. If it is considered that a cause of the collapse of the steering column is that the shaft disengaged from the universal joint resulting in the column giving way:
(e) If due to fretting wear, did it include the bolt and splined region of the shaft, and if so, to what extent?
Yes. The fretting produced sufficient wear to allow the shaft to move some 20mm axially, allowing disengagement of the joint.
12. What, if any, design strategies were capable of being implemented to reduce fretting wear and what would be the approximate cost (as at 1989) of implementing such design strategies in the manufacture of the vehicle?
The only guaranteed method is to eliminate all movement so as to remove all possibility of fretting. Fretting wear is an inherent feature of this type of joint.
13. What, if any, design strategies were capable of being implemented which would have prevented the giving way of the universal joint?
(1) In anticipation of the event that the clamp bolt and grub screws all become loose, fretting wear could be reduced by limiting the axial movement of the intermediate shaft through the bearing at the firewall to, say, no more than 3mm. This would ensure that 17mm of spline length of the universal joint would remain engaged and could be achieved by, eg:
(a) having a design condition where the shoulder on the shaft is located 3mm (not 25mm) away from the bearing. If there are significant build dimensional variations with the truck, this may require the use of selective spacers and a checking procedure on assembly. The cost would be small – possibly 10 minutes additional assembly time.
(b) limiting the travel in the sliding joint to the lower (in the engine bay) shaft. This could be achieved by fitting a sleeve over the male sliding element and would not affect the assumed commonality that this shaft has with truck models having a tilting cab. Again the cost would be small.
(2) Adopt a non bolted design."
47 Evidence was
given that a welded universal joint was one form of non-bolted design that could
operate in substitution for the bolted
design that failed in the present case.
This emerged from the affirmative answer given by the experts following the
conclave to
this question:
"14. Would a design strategy of replacing the clamp splined connection with a welded connection eliminate the failure mode of the steering column as experienced by the vehicle in the accident?"
48 The conclave also produced what
amounted to a similar response to the following question:
"30. Does the use of a welded connection eliminate the risk of loose joints, provided that the welding is done properly?
The welded joint will eliminate the type of failure experienced in this case."
49 One of the experts, Professor Druce
Dunne, provided the following opinion in his report dated 17 January 2005:
"7. Conclusions
Failure occurred by wear. At least a significant part of the wear that led to failure was by fretting – a failure mode that is characteristic of nominally stationary joints that are subjected to relative motion of the mating surfaces due to vibration. Fretting is known to be possible in nominally stationary joints, like the interference fit between shaft and bolt used in the present case. Although fretting wear is difficult to prevent, appropriate joint design and materials selection can be used to reduce the susceptibility to this type of wear . . .
It is concluded that fretting progressively changed the dimensions of the mating components allowing more pronounced relative motion and the development of more rapid material loss by adhesive and abrasive wear. It is expected that for the joint design and the materials used, regular inspection and maintenance would have been recommended to check for axial play and to periodically re-tighten or replace the high tensile bolts."
50 In the same
report, Professor Dunne suggested that in order to prevent or limit wear by
fretting, there were several design strategies
that he would recommend. These
were:
(a) Redesign of the joint to produce more effective locking.
(b) Elimination or reduction of the vibration transmitted to the joints by use of vibration damping.
(c) Reduction of slip at the mating surfaces by increasing the pressure between them.
(d) Increase of joint friction by using high friction surface coatings.
(e) Redesign of the joint with an elastomeric inter-layer that prevents metal-to-metal contact.
(f) Use of a liquid or solid lubricant between the two surfaces.
51 The second defendant's response to these allegations is to argue that
the case raised against it is fatally afflicted with the
reasoning of hindsight.
It argues that the plaintiff is in effect urging a counsel of perfection by
reference to the fact that the
accident happened at all, and says the fact that
the universal joint was a component uncontroversially central to the steering
failure
does not thereby demonstrate that it was a component designed and
released in breach of any duty owed to the plaintiff.
52 The second defendant emphasised that the evidence against it, upon
which the plaintiff sought to rely, consisted in summary of
the following
matters:
(i) The intermediate shaft was able to disengage from the universal joint because the pinch bolt was loose and the grub screws were either loose or one was missing altogether.
(ii) Neither of those circumstances was caused by any fault on the part of the second defendant.
(iii) The truck was designed, manufactured and intended to be operated with the pinch bolt tightened to a torque setting of between 45Nm and 50Nm with the grub screws in position and located to the intermediate shaft.
(iv) Upon the uncontested basis that the pinch bolt was tightened to the correct specification at the time of manufacture, the pinch bolt did not, and could not, loosen of its own accord or through the normal operation of the truck. There was therefore some other act or intervention by a third party that led to it being loose at the time of the accident.
(v) If the pinch bolt was tightened as specified the intermediate shaft could not move axially. A force of one tonne was necessary to result in such movement and this would not occur during normal operation of the vehicle.
(vi) The flange bearing was seized prior to the accident. Once seized, this prevented proper and smooth operation of the intermediate shaft and would be accompanied by noise. Loosening the grub screws and greasing the shaft may overcome the effects of the seized bearing.
(vii) There were polish or witness marks in the shaft suggesting that the bearing had been seized for some considerable time prior to the accident.
53 In simple terms the second
defendant says that there is no case against it that the universal joint was not
properly adjusted when
it left its control and that the experts agree that what
occurred could not have occurred to a properly adjusted joint in the course
of
ordinary operations. Therefore the wear that led to the failure of the joint
was the result of interference by others and not
a consequence of poor or
inadequate design. It was not unreasonable for the second defendant to operate
upon the basis that the
pinch bolt would remain properly adjusted and that
slackness in the joint, if it occurred, should have been observed in the normal
course of regular maintenance and corrected. Moreover, it was unreasonable to
impose upon the second defendant a duty of care that
required it to perform to a
standard that anticipated use of the universal joint other than correctly
adjusted as originally intended.
54 There is no direct evidence as to when or in what circumstances during
the operation of the truck the pinch bolt became loose.
The experts opine that
it may have been years rather than months having regard to the extent of the
fretting wear caused by the
movement allowed by the loose pinch bolt. The first
defendant gave evidence, which I accept, that there never was an occasion during
his period of ownership when anything at all was done to the upper end of the
truck's steering assembly. However, the first defendant
gave evidence about
what occurred when he first purchased the truck. That evidence was as
follows:
"Q. Mr Erwin, just taking you back to the time when you purchased this truck, it was, on the documentation it says from Australian Used Truck Centre. Did it also trade as Select?A. Yes, Select Trucks.
Q. That is, I think you said this, it is in Lavington which is a suburb of--
A. Albury.
Q. Albury. When you were in the throws of talking to the sales representative of the vendor, that is the seller, did you have any conversation in respect of something you observed on the steering wheel?
A. Yes. There were markings, numbers underneath the steering wheel and I asked him what they were for.
Q. Do you know the name of this person?
A. No.
Q. Obviously a him?
A. Yes.
Q. I understand that company is no longer in operation is that - you don't know, right. What did he say?
A. He said that they had replaced the steering wheel and did a bit of work to the steering.
Q. Did you ask any more details in respect of that?
A. No. "
55 The steering wheel is in evidence
as an exhibit and still has numbers in white paint or similar on the underside
of one of its
spokes. The first defendant was not challenged about the fact or
content of the conversation to which he deposed. Indeed, the record
of
interview given by the first defendant on 19 April 2004, tendered by the
plaintiff, refers to the same conversation in the following
terms:
"Yes, when I purchased the truck, when I was up in the truck I noticed underneath the steering wheel it had white texta numbers and I, it looked like part numbers from the steering wheel so I, I said to the bloke, I said, What's the numbers under the steering wheel? And he said, We had to put a new steering wheel on it and we did a little bit to the steering, so that's, that's all I know."
56 It should not pass without comment
that the steering wheel assembly fits directly into the upper end of the
universal joint from
which the intermediate shaft was released. The steering
column assembly drawings (Exhibit B) and the steering column itself (Exhibit
D)
make this clear.
57 Mr Lewis, the original owner of the truck, also gave evidence that he
had never had any problem with the truck's steering and had
never performed any
work on the upper universal joint. He sold the truck to the dealer from which
the first defendant purchased
it. The first defendant carried out no work on it
either. Accordingly, the statement made by the representative of the used truck
centre to the first defendant at the time of his purchase provides a cogent and
reasonable explanation of when and in what circumstances
the pinch bolt was left
loose. It also fits with the expert evidence that it was loose for years before
the accident having regard
to the extent of the wear that was evident. It will
be recalled that the first defendant purchased the truck in 1999 and the
accident
occurred in 2002. I find in the circumstances that this is what in
fact occurred.
58 That would have been sufficient to dispose of the plaintiff's case
against the second defendant if it were not for the plaintiff's
contention that
a welded joint should have been used and that if it had been the accident would
have been totally avoided. The plaintiff's
case in this respect is that the
failure to employ a welded joint was a design fault that occurred in breach of
the second defendant's
duty to the plaintiff.
59 Mr Perkins, a representative of the second defendant, gave evidence
about this. He said that the Transtar 4670 model was manufactured/assembled
by
International Trucks, now Iveco, during the period from 1987 to 1990. It
purchased component parts from other suppliers, including
ZF in Europe and Dana
Spicer in the United States. The model was originally built with a pinch bolt
universal joint assembly linking
the top shaft to the intermediate shaft. As
part of a number of changes in 1990, the second defendant commenced to install a
welded
joint/shaft into this model. The welded componentry was cheaper than the
pinch bolt system.
60 Mr Perkins also gave the following evidence:
"Q. How many of the models identified on that document used the pinch bolt system, that is the pinch bolt system of connecting the top and intermediate shaft by way of a universal joint?A. Connection to the steering column in all those models is via pinch bolt connection.
Q. Has that always been the case with all those models?
A. Yes, yes, that's, it is an industry norm.
Q. Going back to 1989, we know that this particular vehicle was manufactured in 1989, that is assembled by Iveco. I think you have already said Iveco assembled a number of different models of trucks at that time?
A. (Witness nodded).
Q. How many of those models used the pinch bolt system back in 1989, that is the models that were being assembled in 1989?
A. Oh, they all did except for the S series.
Q. The S series?
A. Yes, the Acco used a pinch bolt connection, the T-line used a pinch bolt connection, the Turbotech, the Turbostar, all used pinch bolt connections.
Q. Back in 1989 did a number of other manufacturers of trucks use the pinch bolt system?
A. Yes, it is, it was the industry norm and still is today.
Q. Can you name some of those manufacturers?
A. Oh, Kenworth, Volvo, Scandia, Freightliner.
Q. You have searched for the manufacturing records of this particular vehicle, haven't you?
A. Yes.
Q. They are no longer available?
A. The, you are referring to the documents when the vehicle was built, yes.
Q. Yes, I'm referring to the documents produced along the assembly line?
A. Yes.
Q. They are not longer available?
A. Not for that vehicle, no. "
61 Since around
1994 the second defendant has manufactured approximately 14,500 vehicles, all of
which have used the pinch bolt system.
During the same period in Europe the
corresponding number was approximately 450,000.
62 In these circumstances the second defendant made the following
submissions. The plaintiff bears the onus of proof in establishing
negligence on
the part of the second defendant. No inference arises merely because the
accident occurred. The manufacturer of a
motor vehicle owes a duty of care to a
road user but only to take such care as a reasonably prudent manufacturer would
take in the
circumstances: Adelaide Chemical & Fertilizer Co Ltd v
Carlyle [1940] HCA 44; (1940) 64 CLR 514. As was said in Bull v
Rover Mowers (Aust) Pty Ltd [1984] 2 Qd R 489 at 499:
"The duty of the manufacturer did not, however, extend to producing a product which was accident proof or which would not wear out, and it was not an insurer".
63 A manufacturer is not obliged to
take precautions against a risk that may arise when the use to which the product
is put is so
unusual or improper as to make such use wholly unreasonable that it
falls outside the range of any man's reasonable contemplation:
Bicer v
McDonalds Australia Ltd [2001] NSWSC 218 at par [44]. The standard of
care to be applied when one is dealing with a machine is that of a reasonably
competent engineer: Suosaari v Steinhardt (supra) at 499.
64 The second defendant emphasised that any inquiry about a breach of
duty of care must identify the reasonable person's response
to foresight of the
risk of the occurrence that the plaintiff suffered. It necessarily takes place
after the event but must identify
what the response would have been by the
person looking forward rather than looking backwards or with the benefit of
hindsight.
65 In Dovuro Pty Ltd v Wilkins [2003] HCA 51; (2003)
215 CLR 317 at par [34], McHugh J said this:
"[34] If negligence law is to serve any useful social purpose, it must ordinarily reflect the foresight, reactions and conduct of ordinary members of the community or, in cases of expertise, of the experts in that particular community. To hold defendants to standards of conduct that do not reflect the common experience of the relevant community can only bring the law of negligence, and with it the administration of justice, into disrepute. That is not to say that a defendant will always escape liability by proving that his or her conduct was in accord with common practice. From time to time cases will arise where, despite the common practice in a field of endeavour, a reasonable person in the defendant's position would have foreseen and taken steps to eliminate or reduce the risk that caused harm to the plaintiff. But before holding a defendant negligent even though that person has complied with common practice, the tribunal of fact had better first make certain that it has not used hindsight to find negligence. Compliance with common practice is powerful, but not decisive, evidence that the defendant did not act negligently. And the evidentiary presumption that arises from complying with common practice should be displaced only where there is a persuasive reason for concluding that the common practice of the field of activity fell short of what reasonable care required."
66 His Honour continued at par [38]
as follows:
"[38] A defendant is not negligent merely because it fails to take an alternative course of conduct that would have eliminated the risk of damage. The plaintiff must show that the defendant was not acting reasonably in failing to take that course. If inaction is a course reasonably open to the defendant, the plaintiff fails to prove negligence even if there were alternatives open to the defendant that would have eliminated the risk."
67 In the circumstances of the present
case I am also required to have regard to the provisions of ss 5B and 5C of the
Civil Liability Act 2002.
68 In my opinion the plaintiff has not established negligence on the part
of the second defendant. To hold the second defendant to
the standard of
conduct for which the plaintiff presently contends would be to enforce standards
that do not reflect the common experience
of the relevant community. The second
defendant complied with what was ordinary practice. The evidence was that a
pinch bolted
universal joint was the industry norm. There is to my mind no
persuasive reason for concluding that the common practice of producing
universal
joints in the steering mechanism of the truck in this case fell short of what
reasonable care required.
69 The plaintiff's case was that the pinch bolted universal joint was a
flawed design because a lack of proper adjustment of the bolt
could lead to wear
with consequences of the sort that befell the plaintiff. The undisputed
evidence was that a reasonably available
welded alternative would have obviated
this risk entirely. However the fact that a risk of harm could have been
avoided by doing
something in a different way does not of itself give rise to or
affect liability for the way in which the thing was done and the
subsequent
taking of action does not of itself give rise to or affect liability in respect
of a risk.
70 The plaintiff's case was that the second defendant should have
designed the universal joint so that it would never fail. In the
events that
occurred, the joint failed following inappropriate adjustment, which inadequate
maintenance failed to detect. This occurred
over a relevant service life in the
custody of the first defendant of something in excess of 500,000 kilometres and
as much as 600,000
kilometres. The pinch bolt was not correctly tightened and
the grub screws had been readjusted or neglected. The failure that led
to the
collision, therefore, did not take place in the course of what a reasonable
manufacturer might similarly have anticipated
would be the normal use of the
vehicle. The steering system was only as strong as its weakest link and the
weakest link was not
the fault of the second defendant.
71 The plaintiff relied upon the adjustment of the grub screws as, in
effect, a secondary safety feature. In other words, three of
the four experts
considered that the intermediate shaft could and would have been retained in
position if located to the bearing
by grub screws adjusted as designed. The
evidence suggests, however, that this was purely a matter of happenstance and
not a safety
design feature of this steering system. The witness marks on the
shaft were such as to indicate that the grub screws had long before
this
accident ceased to work as designed, thereby only emphasising the legal distance
between the plaintiff's case and the lability
of the second defendant, which was
entitled to anticipate that this truck would have been maintained in a way that
would have detected
both the universal joint in a state of incipient failure and
the fact that the intermediate shaft was not fixed to its bearing.
The
suggestion that the second defendant should have produced a welded joint that
would not have failed is an approach spawned by
the wisdom of hindsight. The
universal joint, properly adjusted and maintained, was effectively not subject
to failure. This is
a case in which it was appropriate for the second defendant
to do no more than it did.
72 Nor was there evidence to suggest that the second defendant should
have been on notice from prior failures that the events that
injured the
plaintiff might occur. There was no evidence that at the time that the truck
was designed there were any circumstances,
incidents, complaints, reports or
accidents that might have led a competent engineer exercising reasonable care
designing the steering
mechanism for this truck to have done anything more than
was done in fact. There is no evidence to suggest the happening of a combined
event of the type that occurred in this case either before or since the design
and manufacture of the truck.
73 The first isolated report as described by Mr Anderson is dated after
the date of the truck's manufacture. It refers to the vehicle
being returned
because the locating bolt to the universal joint was loose. The bolt was
tightened. There is no suggestion in the
document that it was left loose at the
date of manufacture and no other documentation suggesting that any further
problems arose
once it was correctly adjusted. The last document annexed to Mr
Anderson's report is dated 23 April 1989 and was prior to the manufacture
of the
truck. The nut was missing from the retaining bolt and the bolt worked out.
74 This does not amount to evidence that would suggest that a reasonably
competent designer of a motor vehicle should reasonably have
had regard to the
prospect of the occurrence of the two events that combined in this case to
produce the accident that injured the
plaintiff. Section 5B requires that the
risk be not insignificant. There is no evidence in this case that supports a
contention or a finding that this
risk was not insignificant. For all this case
has produced, it may be that this event has never previously occurred. It would
be
surprising if it had. The steering was manufactured according to the
industry norm and still is. Not one piece of the evidence
and none of the
expert opinions suggests otherwise.
75 One further matter requires comment. The intermediate shaft had a
shoulder located above the bearing in the flangette at the firewall.
This was
apparently created as the result of the machining of the shaft to reduce its
diameter to fit the internal dimensions of
the bearing. If the shaft were to
collapse, as it did in this case, the shaft could slip no further than the point
where the shoulder
reached the bearing where it would stop. There was some
faint suggestion that the second defendant's design was actionably faulty
because this shoulder had not been engineered to sit lower down closer to the
bearing and at a distance less than the length of the
splined upper section of
the intermediate shaft that was fitted into the pinch bolted universal joint
above it. If it had been so
engineered, according to this argument, the
shoulder would have engaged the bearing before the upper shaft parted company
with the
universal joint and the failure would not have occurred.
76 As accurate an assessment of the likely sequence of events as that
summary may be in fact, it is in my view a prime example of
the type of
impermissible retrospective reasoning that is to be avoided. There was no
evidence to suggest that the shoulder had
been designed and engineered as a
secondary safety feature in the first instance and its potential elevation to
that status appears
to me to be the product of the experts' detailed
consideration and reconstruction in hindsight of the cause of the steering
collapse.
It falls in my view to be assessed in terms similar to the
contentions concerning the welded joint. It did not amount to a failure
by the
second defendant to design the steering mechanism in conformity with its duty of
care as a prudent manufacturer.
Conclusions in relation to the second defendant
77 In my view the steering did not fail as the result of any absence of
reasonable care by the second defendant in the manufacture
or design of the
truck. It was not required to design a vehicle that would continue to be safe
for use after two million or so kilometres
and be accident proof in the face of
no servicing to the steering mechanism for at least three years and where there
has been independent
conduct by a third party inappropriately adjusting the
universal joint pinch bolt to allow for abrasive and adhesive wear to occur
and
to compromise the effectiveness of the joint. The availability of another,
different design that would have obviated the risk
is not automatically or
necessarily co-extensive with the existence, or a finding, of a breach of duty.
The second defendant did
not breach the duty that it owed to the plaintiff.
The first defendant's cross claim against the second defendant
78 The cross claim based upon the same allegations of negligence that the
plaintiff relied upon fails for obvious reasons.
79 The first defendant alleges that the second defendant is liable to it
in accordance with the provisions of the Trade Practices Act 1974
as follows:
"75AD If:
(a) a corporation, in trade or commerce, supplies goods manufactured by it; and
(b) they have a defect; and
(c) because of the defect, an individual suffers injuries;
then:
(d) the corporation is liable to compensate the individual for the amount of the individual's loss suffered as a result of the injuries; and
(e) the individual may recover that amount by action against the corporation; and
(f) if the individual dies because of the injuries--a law of a State or Territory about liability in respect of the death of individuals applies as if:
(i) the action were an action under the law of the State or Territory for damages in respect of the injuries; and
(ii) the defect were the corporation's wrongful act, neglect or default."
"75AE (1) If:
(a) a corporation, in trade or commerce, supplies goods manufactured by it; and
(b) they have a defect; and
(c) because of the defect, an individual suffers injuries; and
(d) a person, other than the individual, suffers loss because of:
(i) the injuries; or
(ii) if the individual dies because of the injuries--the individual's death; and
(e) the loss does not come about because of a business relationship between the person and the individual;
then:
(f) the corporation is liable to compensate the person for the amount of the person's loss; and
(g) the person may recover that amount by action against the corporation.
(2) For the purposes of this section:
(a) a profession is taken to be a business; and
(b) a relationship between employer and employee or a similar relationship is a business relationship."
80 The cross claim does
not plead the first defendant's case, relying upon these provisions, in any
particularly detailed way. However,
the second defendant responds to the claim
by emphasising the following matters. First, there is no defect within the
meaning of
s 75AC, particularly having regard to s 75AC(2)(d), (e) and (f), (3)
and (4). Secondly, s 75 AD provides a statutory remedy only to individuals who
suffer injuries and only for the amount of the individual's loss. Thirdly,
the
loss is a loss in respect of which an amount has been, or could be, recovered
under law that relates to workers' compensation
in which case s 75AI
specifically excludes the operation of Part VA of the Trade Practices
Act. In my opinion the first and third of these propositions are each
sufficient to dispose of the cross claim. This is for the following
reasons.
81 First, the goods in question for present purposes are the universal
joint and the flange bearing assembly. Neither is defective
in my view. The
meaning of defect is to be found in s 75AC as follows:
"75AC (1) For the purposes of this Part, goods have a defect if their safety is not such as persons generally are entitled to expect.
(2) In determining the extent of the safety of goods, regard is to be given to all relevant circumstances including:
(a) the manner in which, and the purposes for which, they have been marketed; and
(b) their packaging; and
(c) the use of any mark in relation to them; and
(d) any instructions for, or warnings with respect to, doing, or refraining from doing, anything with or in relation to them; and
(e) what might reasonably be expected to be done with or in relation to them; and
(f) the time when they were supplied by their manufacturer.
(3) An inference that goods have a defect is not to be made only because of the fact that, after they were supplied by their manufacturer, safer goods of the same kind were supplied.
(4) An inference that goods have a defect is not to be made only because:
(a) there was compliance with a Commonwealth mandatory standard for them; and
(b) that standard was not the safest possible standard having regard to the latest state of scientific or technical knowledge when they were supplied by their manufacturer."
82 The goods
in question did not have a defect. Their safety was entirely what persons
generally are entitled to expect. The evidence
in this case establishes that
both items had seen something in the order of 2,000,000 kilometres of use in the
truck with no maintenance
from the first defendant for the whole of the time
that he owned it. My findings about these items in the context of the second
defendant's alleged breach of duty to the plaintiff effectively foreclose upon
the contention that the items were defective within
the terms of the relevant
provisions.
83 Secondly, in respect of the third proposition, I was referred to the
decision of Wood CJ at CL in Lanza v Codemo [2001] NSWSC 72 at
pars [184] to [188] as follows:
"[184] Part VA of the Act, within which these provisions are included, was introduced by Act No 106 of 1992. The Explanatory memorandum for the Bill, pursuant to which it was introduced, provided:
'40. The new Part VA is being introduced as a consumer protection measure. Loss caused by work-related injuries has therefore been excluded, as it is considered that this field is comprehensively regulated under existing worker's compensation regimes. Similarly, loss which is regulated by way of international agreement has also been excluded.'
[185] It is here the case the plaintiff's injuries were caused by a work related injury. It is also the fact that the plaintiff has already recovered some amounts under a law of a State which relates to worker's compensation, from Yoogali or its insurers.
[186] The question which arises is whether S 75AI operates, where the plaintiff is entitled to independent recovery from his employer under a law relating to worker's compensation, to bar all recovery under S 75AD; or operates to limit recovery to such sums of money that would otherwise be recoverable beyond any cap arising under the relevant workers compensation legislation; or operates to limit recovery in relation to those heads of loss for which recovery is not possible under the relevant workers compensation legislation.
[187] The section is ambiguous, and it is accordingly appropriate to have regard to the explanatory memorandum, a reading of which inclines me to the view that a person in the position of the plaintiff, who has the protection of workers compensation legislation, cannot also bring a claim under the Trade Practice Act against a corporation where goods manufactured and supplied by it have a relevant defect, that leads to an injury to the plaintiff in the course of his work.
[188] It was argued, however, by the plaintiff, that the present was not a case in which a loss "could be recovered" under workers compensation legislation, because of the operation of S 151E of the Workers Compensation Act which required the plaintiff to seek recovery under the Motor Accidents Act. However, recovery under that Act is confined to recovery for fault, whereas the plaintiff was also entitled to receive benefits, without proof of fault under the Workers Compensation Act, and has in fact received such benefits."
84 Section 75AI is as follows:
"75AI Section 75AD, 75AE, 75AF or 75AG does not apply to a loss in respect of which an amount has been, or could be, recovered under a law of the Commonwealth, a State or a Territory that:
(a) relates to workers' compensation; or
(b) gives effect to an international agreement. "
85 In my opinion the loss in
respect of which the first defendant seeks recovery under either ss 75AD or 75AE
is a loss in respect
of which an amount has been or could be recovered under a
law of New South Wales that relates to workers' compensation. The plaintiff
was
in the course of a journey to his work and was paid benefits under the relevant
legislation in respect of the injuries that he
sustained. The words "in respect
of which an amount has been paid" are wide and contextually unconstrained. They
extend to cover
the payment of workers' compensation benefits to the plaintiff
in this case. The Explanatory Memorandum referred to in the judgment
of the
Chief Judge in Lanza v Codemo (supra) uses the words "loss caused
by work related injuries" which are wider still.
86 In my view the first defendant's cross claim relying upon the
Trade Practices Act 1974 cannot withstand the force of either one
of the second defendant's submissions and should be dismissed.
Conclusion
87 It follows that there will be a verdict for the plaintiff against the
first defendant in the amount that has been agreed. There
should be a verdict
for the second defendant on the plaintiff's claim against it. The first cross
claim should be dismissed. I
will direct the parties to bring in short minutes
of order to reflect these proposals and I will hear the parties in respect of
any
costs orders that should be made at some convenient date to be arranged in
consultation with my Associate.
