(e) The composite cross claim by Pabesu /Worley insofar as it remains against:
(i) Wong,
(ii) Vulcap,
(iii) Jax (twenty first cross claim).
11 The vast bulk of the hearing time was occupied in adducing expert evidence relating to the tyre and its impact upon driving performance. Save some observations by Mr Wingrove, an engineer to whose evidence I will later refer, no expert was able to examine the tyre, no trace of which could be found after it had been impounded by police. This is not an implied criticism as, for reasons which will appear, police interest in the incident lapsed. Not only was the handicap of absence of view common to the expert witnesses but their evidence was necessarily elaborated to deal with possible alternative findings of fact. Initial fact finding will considerably reduce the requisite reference to a large volume of evidence founded upon the hypotheses about facts not ultimately accepted as established.
12 I turn to the circumstances leading to the collision. Ms MacIntosh was driving her car on the left (slow) lane of the motorway at 110 kph. She heard a slapping noise which I am satisfied was the detaching tread of the rear nearside tyre of the vehicle at a time it was to the rear of hers and in the right (fast) lane. She contemplated that the noise may have been coming from her car until Wong brought the vehicle beside hers and proceeded to overtake it. Thereafter the vehicle was seen to fishtail with a slight left and then a right deviation after which it continued through the verge dividing the traffic flow and into impact with oncoming cars.
13 A Mr Richards was in the same lane as Wong about forty yards behind and therefore had an uninterrupted view of the rear of the vehicle. I do not accept his estimate of constant speeds of his and Wong's vehicles at just under the speed limit and I prefer the evidence of Ms MacIntosh, however I do accept Mr Richards' observation that the brake lights on the vehicle did not illuminate and I conclude that Wong made no attempt to slow the vehicle by the use of his brakes.
14 Police, including accident investigation specialists visited the scene. It was through them that Mr Wingrove's services were retained but upon his preliminary report being orally given, a conclusion was reached by Constable Van der Hoek that that "tyre failure was the contributing factor to the collision and as such no further action is contemplated against Wong". I infer that this is why no further police interest was taken about the whereabouts or disposal of the damaged tyre.
15 On 14 July 1994, prior to Constable Van Der Hoek's decision, Wong had been interviewed with the assistance of an interpreter. In the course of that interview he said that he was in the fast lane and "all of a sudden I heard a loud noise from my car and there was a very vigorous vibration". He claimed that he attempted to reduce the speed "to slow down by pressing on the brake". He could not stop the car and lost control.
16 Questioned about this Wong said that he first looked in the mirror to see if he could move into the slow lane but there were too many cars coming and it was then he tried to slow down "without much success".
17 He said he was travelling at between ninety five and a hundred kph. There were about five seconds between hearing the noise and feeling the vibrations and the commencement of the vehicle's drawing to the right. His explanation for his claimed speed was ………."because the tyre was a retread so I usually, I would always keep the speed below the speed limits so the speed limit on that freeway was 110 so I would have keep it at about 100".
18 Specifically Wong estimated that about twenty seconds elapsed between first hearing the noise at the back of the vehicle and the collision.
19 As I have said, I accept the evidence of Ms MacIntosh. I note that no one suggested that I should not. Such acceptance leads to two possible conclusions concerning Wong's driving conduct.
20 If Wong's speed was only slightly more than that of Ms MacIntosh then, after the noise and vibration were detectable, time had to elapse during which Wong had to gain upon, draw alongside and pass Ms MacIntosh's car. If that was the case, it is probable that Wong continued to advance for somewhat longer than twenty seconds and, even if he was travelling only mildly faster in comparison to Ms MacIntosh at 110 kilometres per hour, I am satisfied that the noise would have been accompanied by marked vibration and a reasonably prudent driver would have slowed either by allowing the vehicle to decelerate or by braking. Wong did neither. Mr Richards was some forty yards to the rear and presented no obstacle to slowing down. If that had been done it is probable that Wong would have maintained sufficient control of the vehicle so as not to cross the whole dividing verge and collide with oncoming traffic.
21 The alternative, in which events might have occurred in a shorter time span such as the twenty seconds estimated by Mr Wong, involved a greater excess in the speed of the vehicle over the upper mark of the limit at which Ms MacIntosh was proceeding. Again, ordinary prudence would contra indicate maintaining a high speed and accelerating past Ms MacIntosh's vehicle when an unidentified noise and marked vibration were manifesting themselves.
22 It was submitted on behalf of Wong that I should find that he was not negligent. I accept that when he purchased the car the dealer agreed to supply new tyres but, given Wong's answers to Constable Van Der Hoek I consider "new" was understood by Wong to mean replacement of those on the vehicle at the time and that he knew that the "new" tyres were retreads. Odometer readings were available as at the date of purchase (18 November 1993), the pink slip inspection (16 March 1994) and the accident (6 April 1994). The readings were respectively 168,615, 185,376 and 188,151 kilometres. It follows that from the date of purchase until accident the tyre had been used for 19,536 kilometres and 3,015 kilometres after the pink slip inspection when Worley had marked the result of inspection of tyres as "good". I am unpersuaded that a prudent owner or driver should have been aware before the occurrence of symptoms of noise and vibration that the tyre was defective and capable of causing an accident. I will need to detail some matters about the defect later but for the purposes of assessing the conduct of Wong I express that conclusion now.
23 I find that Wong was negligent in his care and control of the vehicle on the occasion of the accident. I find that there was ample warning of imminent danger in terms of noise and vibration and that the reasonable response of a driver was to slow down and, if unable then to make adequate assessment, stop and investigate. The existence of other traffic would not prevent this and the option of stopping on the verge was available if the left lane was not clear. Any reduction in the time available for Wong to make decisions was relative to his speed which was in excess of the prescribed limit. I reject the opinions and the argument which proposed that it would take skill above the ordinary to safely cope with the situation. Given the high speed of Ms MacIntosh's car, and Wong was probably accelerating to achieve overtake, I conclude that he drove at excessive speed regardless of the "symptoms" in ignorance of their cause and made no attempt to implement a reasonable course of slowing the vehicle.
24 Reference was made to Roncoli v Tolson 1993 Aust Tort Reports 81-201. This was a case essentially determined on its facts by a full court of the Supreme Court of South Australia. There was a form of defect manifested in what was described as "belt edge tread separation" diagnosed by engineers after a driver had applied the brake immediately after hearing a "bang" and lost control. In that case it was held there were insufficient facts from which to draw an inference of negligence. The present case is in marked contrast not the least in Wong's "pressing on regardless" despite his ignorance of the source of symptoms which he had discerned.
25 My conclusion on these issues is in accord with opinions of experts which I accept. Mr Wingrove stated:
"The driver of the vehicle, shortly before the catastrophic tyre failure occurred, ought to have observed the 'tell tale' signs warning the driver that there was something wrong with the tyre and thereby placing the driver on alert to reduce speed and stop the vehicle to inspect the tyre and wheel.
Had the driver of the vehicle stopped the vehicle and inspected the tyre in question when either the vibration commenced or when the flapping noise commenced, the accident more than likely would have been avoided".
26 There is added emphasis in the evidence of Mr Simpson whose subjective experience (as described) is instructive. He wrote:
"The writer is of the view that a competent driver should not have lost control of the vehicle in the manner that Mr Wong clearly did on this occasion and, indeed, the writer is of the opinion that had Mr Wong braked heavily, then the accident would not have occurred.
The writer has had an off-side rear tyre failure in a sedan version of the same vehicle (EA Ford Falcon) as that driven by Mr Wong and no serious forces were applied to the vehicle that would cause the control of the vehicle to be lost from the driver (the writer). In this particular instance, the actual off-side rear tyre was punctured at high speed and did, in fact, burst through overheating rather than a simple tread separation".
27 There was debate about the expertise and the content of opinions on this aspect expressed by Mr Styles and for the purpose of this issue, as well as ignoring those parts of his reports rejected, it is apt to put his evidence to one side as it could not affect my conclusion. Mr Makepeace's evidence is not germane, nor is that of Mr Veen.
28 It is a fair summary of the opinion of Mr Keramides that "under the circumstances the actions of the driver were within those expected of a 'normal' driver in his position". I prefer other opinions which are in harmony with my own assessment above expressed.
29 The impression I gained was that Mr Gilmore had taken up Wong's cause. I do not suggest that his adherence to the Expert Witness Code of Conduct was suspect but rather that, probably subconsciously, he had to an extent donned the mantle of advocacy. His reports are considerably expanded with commentary upon and debate about views expressed in other reports some of which were not, in the event, tendered. However, insofar, as he expressed disagreement or criticism, for example, of Mr Simpson's views on controllability (p.11, Report of 4 July 2001, part of Exhibit W12) I am unprepared to act upon Mr Gilmore's opinions.
30 I should interpolate that I do not accept Wong's evidence that he applied his brakes. There were no road or skid marks to support this assertion and it is contradicted by the observed absence of brake lights testified by Mr Richards.
31 The alternative basis of liability alleged against Wong requires a finding that he was negligent in failing to observe the incipient defect in the tyre before proceeding on the fateful journey. Again, there is a variety of opinion among the experts but it is not necessary to engage in elaborate recitation. I am comfortably satisfied that Wong was negligent as above stated in failing to react appropriately to the occurrence of symptoms but I am unable to be satisfied that a reasonably prudent vehicle owner would have inspected and recognized emergent radial run out.
32 However, the plaintiff has succeeded in proving requisite negligence against Wong.
33 As mentioned Mr Wingrove was called in by police to examine the tyre and some notes of his preliminary inspection were produced (Exhibit D). He did not proceed to a full examination apparently because, once he had advised police that there genuinely had been a tyre failure, further investigation was not required. Part of the constituency of a steel belted radial tyre (such as the tyre) are two plies of steel of a mesh style which are locked to each other and within the outer rubber compound in which the tread is grooved. Damage to the tyre can be caused by the separation of the steel plies. It is a recognized defect. When it happens the movement of the steel, one ply against the other polishes the surfaces. Mr Wingrove saw this sign. At inspection there was also a significant part of the rubber compound tread missing, that is to say there was a gap in the remnant tread surface. I am satisfied that there was tyre failure culminating in damage to the tread observed by Mr Wingrove which was precipitated by separation of the steel plies. Mr Wingrove advanced further opinions but it is convenient to deal with them and pertinent expressions by other experts in the context of the situation of the various parties.
34 Both Worley and Wong gave evidence about the inspection approximately three weeks before the accident in respect of which the pink slip was issued. Neither impressed me as having any true recollection of the specific events of this routine occurrence and in the case of Worley his evidence derives from usual practice and in the case of Wong, reconstruction of what would have happened. In both cases, their evidence was manifestly slanted in favour of their respective adopted positions.
35 The critical question is what, if anything, untoward Worley ought to have discovered in carrying out his inspection. In performing his task Worley's duty had specific requirements laid down by the RTA and they were that he visually inspect each road tyre and reject it if any tyre had less than 1.5 mm tread depth on the surfaces which normally contact the road or the tyre had deep cuts, bulges, exposed cords or other signs of carcase failure (Rule 104).
36 The liability of Worley was alleged to derive from negligent performance of the inspection.
37 The tyre travelled a further 3000 kilometres on road surface between the inspection and the calamity at Pendle Hill. It is not without significance that until that occasion, Wong had neither felt nor observed anything irregular about the tyre. I do not suggest that he made any specific inspection but at all times the vehicle was in his possession and used by him. I interpolate that there was evidence of tyre pressure on other tyres fitted to the car considerably above the recommended levels but I am unable to utilize this information to determine any issue. As I do not accept that either Worley or Wong presented credible evidence of what was seen on 16 March, I turn to consider the experts' views as to what ought to have been observable at that time.
38 The specific material for deliberation upon by the experts consisted essentially of Mr Wingrove's notations.
39 Mr Wingrove opined that the external sign of an internal problem of separation defect would in the course of time manifest itself in a "radial runout" that is, if one were to rotate a tyre there would be an observable unevenness in the tread between the shoulders of the tyre. The extent of polishing of the steel indicated that there was not a localized failure but a failure which had migrated around the tyre over an undetermined period of time. That observation would suggest that the sign of radial runout would have been provoked by running the defective tyre over whatever period that was. He conceded that it was possible that it might have occurred after Worley's inspection and at any time between the inspection and about 500 kilometres before the accident. What requires proof is that the radial runout was probably there at the time of the inspection and capable of being seen. Mr Wingrove's evidence falls short of establishing that probability.
40 Mr Simpson, a consulting engineer, considered the polish on the steel plies and explained the process whereby heat and centrifugal forces create a "bubble" under the tread causing that portion of the tread where there was contact with the road surface to wear more rapidly than tread unaffected by the separation. I note the debate about the accuracy of his interpretation of localized wear but his opinion that the telltale visual sign was capable of being produced within a road distance of 500 kilometres, and certainly within 3000 kilometres, travelled after inspection does not affix Worley with liability.
41 Mr Veen, an automotive engineer, expressed the probabilities as favouring separation in the carcase developing no earlier than between 1000 and 1500 kilometres prior to failure. The ultimate separation of tread was itself caused by the internal separation of metal plies and was, of course, evidenced in the noise heard by Wong. On the issue of observability of radial runout or observable sign (various labels were assigned by witnesses) he said that he would not rule out the possibility that uneven wear was present to some small extent as at the pink slip inspection date, but thought it improbable that this would have been observable on inspection or noticeable while driving or even readily detectable at that point, that is 3000 kilometres prior to failure. Specifically he testified that a sign of separation defect would not have been recognizable.
42 Mr Anderson was also a consulting engineer. His relevant testimony was that:
"…………..it is more probable than not …….. that 3000 kilometres before the failure there would be little, if any, evidence present for normal inspection. Possibly if someone took the tyre out and measured the tread depth very carefully three may well be some indication. But I consider it most unlikely for routine inspection that would be evident."
43 Worley was conducting a routine inspection with particular reference to the requirements of RTA Rule 104. Contradictions in the testimony between him and Wong about the incidents of inspection, jacking up the car etc. lose any necessity for resolution if nothing untoward would have been seen on inspection in any event.
44 The issue was raised with Mr Makepeace, a businessman with a long association with and participation in the retreading industry, in cross examination. He thought a defect of the type under discussion would exhibit itself within 2000 to 3000 kilometres (before failure). He was not categorical and I mention this evidence for completeness to demonstrate that it does not sustain the case against Worley. It is convenient to add that Mr Makepeace offered a theory of penetration of the tyre with consequent upset of the steel ply bind by a foreign object. The examination of the inside lining of the tyre by Mr Wingrove persuades me to dismiss this theory and the opinions based upon it.
45 Mr Gilmore also an engineer, was reluctant to talk in terms of "specific numbers" that is distances travelled by the tyre and although he thought the separation defect may have existed at the time of Worley's inspection, he thought that external signs may or may not have been present. Cross examined about variation in tread he agreed that observable difference in tread depth should "ring warning bells" to a trained mechanic but I do not find in his evidence an opinion that in terms of probability such variation was there to be seen at the relevant time.
46 Two further experts were called. Mr Keramides acknowledged this issue to be outside the scope of his expertise. Mr Style, who like the other experts had multiple facets of qualification and experience, impressed me as rather focussed upon motor sport and its peripheries and he gave no opinion in chief about the issue but, cross examined by counsel for the RTA, ventured the opinion that observable change from radial runout would exist for at least 4000 kilometres and added that he was going "to say five ….. maybe extending it". I am unwilling to give weight to this virtually ad hoc opinion which is in contrast with the unanimity of other experts in the sense of their being "under or over the 3000 kilometres prior to failure" mark.
47 The evidence does not establish that Worley was negligent.
48 Pabesu was sued on the basis that it "was an authorized inspection station" and by its nominee Qasabian certified vehicles as roadworthy. Particulars were given common to Pabesu, Qasabian and Worley. There is also a claim against Pabesu which appears to be based upon misleading and deceptive conduct and false representation in terms of the Trade Practices Act 1974. The particulars focus upon the issue of the pink slip by Worley and there is an allegation that he issued it on behalf of Pabesu and Qasabian. The slip does contain an endorsement of the authorized inspection station number 57948 which is pleaded as belonging to Pabesu for identification purposes, but Worley's evidence that he "occupied the workshop" and was "conducting registration inspections" did not establish any agency on his part for Pabesu.
49 In terms of the Trade Practices Act breach pleading, the particulars demonstrate that a liability in Pabesu would arise if there was established a liability of Worley. Such has not been established and there will be judgment in favour of Pabesu and Worley in the action with consequential effect upon relevant cross claims.
50 I turn to the claims against Vulcap. It is not disputed that, as pleaded by the plaintiff, Vulcap undertook the retreading of the tyre. Allegations of negligence were particularized as follows:
"i. Defective manufacture of the retread tyre;
ii. Manufacture of the tyre with a separation defect therein, whereby the rubber retread was not properly adhered to the original tyre carcase;
iii. Failing to have in place a proper manufacturing process so as to ensure that rubber retreads were properly fixed to original tyre carcases;
iv. Failing to check the tyre for separation defect;
v. Failing to have in place any or any adequate system for checking retread tyres for separation defect;
vi. Res ipsa loquitur. "
51 A further claim was advanced pursuant to s75AD of the Trade Practices Act which so far as is relevant provides:
"75AD Liability for defective goods causing injuries - loss by injured individual
