Mr Beard's expertise
28 Annexed to the report, was a curriculum vitae for Mr Beard which described his occupations as "motor mechanic" and "information technology consultant". His qualifications were summarised as "qualified motor mechanic", "advanced diploma information and technology", and "master degree in computer science".
29 His professional experience is recorded as involving some 10 years as a motor mechanic, during which time he also completed his apprenticeship. In the year 2000 he moved to the business of supplying and servicing computers.
30 In evidence given on the voir dire, as to his expertise, it became apparent that his period of work as a motor mechanic was about eight years. His diploma in information technology involved a three-year course at RMIT, in Victoria. He claimed to have a masters degree in computer science, without revealing its source. He added (Tcpt, 1 October 2003, p 54(32)):
"It actually gives me a doctorate, but I don't use that title in full … ."
31 On the voir dire, Mr Beard was asked a number of questions as to the expertise upon which he relied. He said the issue presented to him was the "different ways that you could override" the engine immobiliser system with which the vehicle was fitted: Tcpt, 1 October 2003, p 55(25). He described the system as electronic. The examination in chief continued:
"Q. What is your expertise?
A. Computers mainly and motor vehicles.
Q. The immobiliser system is?
A. Is virtually computerised. It's an electronic component.
Q. Have you had any experience with electronic components of that style?
A. Not such as immobilisers but ECU and telemetry in motor vehicles, I have, yes.
Q. What's an ECU?
A. Engine control unit.
Q. What was the other thing?
A. And telemetry is like a radio control for a car but tells the pit crew what's going on with a car at any certain time, temperatures, speeds, RPMs and so forth."
32 In cross-examination, Mr Beard was asked further questions about his experience (Tcpt, p 57):
"Q. You've never, never spent any time working on Mitsubishis have you?
A. I've done the odd Mitsubishi from time to time, when I was doing my apprenticeship.
…
Q. When you were doing your apprenticeship that would mean prior to 1995 you worked on the odd Mitsubishi?
A. Yep.
Q. You have no experience, do you, Mr Beard in the differences between the early Mitsubishi Magna models, such as those around 1991 and the 1999 Magna sports?
A. I do know the differences, yes.
…
Q. You've never worked on a 1999 Magna Sports have you?
A. No, I haven't.
Q. You haven't worked on any Magnas at all since prior to 1995?
A. No.
…
Q. Your investigation consisted of, looking up the internet and printing material off the internet, is that right?
A. And visiting Paul Wakeling and McGrath's Mitsubishi, talking to mechanics.
Q. Sitting in a car at McGrath Mitsubishi and pulling something off was that the investigation, the practical hands-on investigation, Mr Beard?
A. No, because a friend of mine has a '99 Mitsubishi Magna Sports and I pulled her car apart.
…
Q. As you said to my friend Mr Lee you have no experience with immobilisers.
A. Not an immobiliser, no."
33 The matter was left with the trial judge, by counsel for the Appellant, in the following terms (Tcpt, 1 October 2003, p 61(10):
"In essence, I suppose, just to clarify what's happened there were some things that were unobtainable in such a short time and were fairly expensive but unattainable and as such we didn't get to the enth stage of actually taking the vehicle. So all we could get to was the stage of we needed someone who could read a wiring diagram, who could read the car manual, and as an expert could do both of those things and then show how it could be done in accordance with what was on the video."
