22 The insurer's counsel also referred to the report of Mr David Dubos, a safety engineer, dated 11 November 2008 (Ex PD4) together with portions the contents of Police and WorkCover files as reference to a "defect". The Police Report indicates that inspection of the trailer revealed that the hydraulic arm connection to the ramp which was welded to the rear of the trailer had snapped away from the trailer. Mr Dubos's report is based on assumptions of fact based on the instructions given by Mr Zhang's solicitor.
23 At best, as far as the insurer is concerned, Mr Dubos reports at paragraphs [46] and [113]:
"46 It is apparent to me that Mr Zhang in interacting with the trailer which had a defective ramp, was working within the system of work provided by Mr Popovic. and Interfreight Transport. That is, he was called upon to handle a ramp which was, unsafely secured and he was subject to the defects in the system of work managed by Mr Popovic and Interfreight Transport.
…
113 On my information, Mr Popovic and Interfreight were operating a trailer with inherent or unacceptable hazards associated with it. The strength and stability of the attachment point for the ramp in question was defective. It is apparent that Mr Popovic and Interfreight introduced the use of the trailer into the work system, and permitted use of the machinery by the Plaintiff without carrying out consultation, hazard identification, risk assessment, supervision or training or control of risks which would have prevented the accident to the Plaintiff. As a result the Plaintiff in using the machinery, experienced a failure of the machine where the attachment of a supporting mechanism failed, and the Plaintiff was severely injured as a result."
24 I accept that there is a reference to the trailer having a "defective ramp" and that "the strength and stability of the attachment point for the ramp was defective" and there is also reference to "failure of the machine."
25 In support of the proposition that clause (b)(8) contains words that are not simple in construction, Mr Zhang pointed to the consideration of causation of accidents by defects and other causes in the High Court cases of Allianz Australia Insurance Limited v GSF Australia and Nominal Defendant v GLG Australia Pty Ltd (2006) 228 CLR 529; [2006] HCA 11 and the Court of Appeal in Zurich Australia Insurance Ltd v CSR Ltd (2001) 52 NSWLR 193; [2001] NSWCA 261 to indicate that the courts have grappled with these issues and come to differing conclusions.
26 Counsel for Mr Zhang submitted that the policy at best is ambiguous. In particular counsel relied on Allianz Australia Insurance v GSF Australia. Allianz Australia Insurance v GSF Australia dealt with the compound issue of whether the injury was caused for the purposes of the definition of "injury" in s 3(1) of the Motor Accidents Compensation Act, during the use or operation of a vehicle by a defect in the vehicle. In Nominal Defendant v GLG Australia the court dealt with the question of whether, for the purposes of s 3(1), the injury was caused by the driving of the vehicle in question. According to counsel for Mr Zhang, in Nominal Defendant v GLG Australia at [27], it was found, similarly in this respect to Allianz Australia Insurance v GSF Australia, that the cause of the injury was the designing and implementing an unsafe system of work. It is not necessary to refer in detail to Allianz Australia Insurance v GSF Australia.
27 In Zurich Australia Insurance Ltd v CSR Ltd the New South Wales Court of Appeal stated at [46], [47] and [70]:
"46 In an approach which, in my opinion, is applicable to the Motor Accidents Act , machinery etc was found to be "defective" if it was not fit for the purpose for which it was designed or the use for which it was intended.
