Defence of Justification - The Safety Allegations
96As mentioned earlier, the factual issues falling for determination in these proceedings concern safety allegations and intellectual property allegations made by the Defendant. In this part of the judgment I will consider the evidence, and make necessary findings, with respect to the safety allegations. Although these findings will be made in the context of the defence of justification arising from the claims in defamation, these findings will be relevant as well to the claims under the FT Act, to which I will return.
97The Defendant did not draw together his arguments concerning safety in closing submissions. However, his evidence and cross-examination touched upon a number of safety issues, including the following:
(a) ease of access of a knife or bottle opener to the active component;
(b) ease of insertion of a coin in the groove and the risk that the active component would be touched in the process of removing the coin;
(c)the fact that promotional material indicates that the Mainline system could be installed in a kitchen near water, where additional safety issues arise from corrosion etc;
(d)the risk of fire;
(e)what are said to be particular safety concerns because of the corner connectors used in the Mainline system;
(f) whether the stamped copper rails in the Mainline system are "fixed in thermoplastic" (see Exhibit U).
98The issues to be determined with respect to the safety allegations are to be considered in light of the evidence and with a sense of practical reality. I agree with the following proposition contained in the Plaintiffs' written submission (paragraph 104):
"In considering the safety allegations, the main issue is not one of absolute safety (which can only be an abstract concept), but relative or real-world safety. Virtually every human activity involves danger, and many aspects of modern life are routinely attended with it: driving motor cars, flying in aeroplanes, engaging in sporting or other recreational activity, all involve real risk, and in each case the question of safety can only be answered in relative terms. Perhaps less obviously, but just as certainly, ordinary domestic activities also involve a certain, but very low, level of risk, activities such as climbing stairs, using electrical appliances, gardening or lighting a barbeque."
The Plaintiffs' Evidence Concerning the Safety Allegations
99The evidence reveals that the Mainline system has been sold since April 2008 in Australia, the United Kingdom, Germany, India and more recently, Lebanon, without incident (T78).
100The evidence reveals that the Mainline system complies with detailed and specific standards, including AS/NZS61534.1:2008 entitled "Power Track Systems" (Exhibit Q) and AS/NZS3112:2004 entitled "Approval and Test Specification - Plugs and Socket Outlets" (Exhibit R). These standards contain both general provisions as to safety and function, and specific requirements relating to safety including fire risk and electrical shock risk.
101Further, the evidence reveals that the Mainline system has been extensively tested by a number of independent testing laboratories, which have produced detailed testing reports in relation to the track components and the power point adaptor components (Exhibits S, T, U, V, W, X, Y, Z).
102The fact that the Mainline system complies with relevant standards was confirmed in a document tendered by the Defendant, being an email dated 16 September 2010 from Peter King, principal investigator with the Department of Services, Technology and Administration (Exhibit 29). Mr King had issued a certificate of suitability dated 28 February 2007, with an addendum dated 8 April 2008 concerning the Mainline system (Exhibit U).
103As mentioned earlier, the Plaintiffs relied upon the evidence of several witnesses with respect to the safety allegations, in particular, Mr Andrews, Dr Grantham and Mr Carmody. The Defendant cross-examined the Plaintiffs' witnesses and tendered a number of documents himself during cross-examination.
Evidence of Mr Andrews
104Mr Andrews is the chief engineer at PDC, and he is in charge of ensuring that the Mainline system meets Australian and international standards. He was previously the design engineer. He holds a Diploma in Mechanical Engineering, a Post-Graduate Certificate of Management and is currently studying for a degree in Masters of Engineering Management (T77).
105Mr Andrews gave evidence that the Mainline system has been sold in Australia, Germany, the United Kingdom and Lebanon with the first sale in April 2008 (T78). It is currently installed at Sydney University and a large school in Sydney, and there are 13 further sites in which it is being installed (T84). Mr Andrews said there had been no safety incident in relation to the product (T109).
106It was the evidence of Mr Andrews, supported by relevant documentation, that the Mainline system has met all applicable safety standards and has been deemed safe for manufacture and sale in Australia and elsewhere. One of the adaptors for the Mainline system has won a design award in Australia (Exhibit O) and overseas (Exhibit P).
107It is noteworthy that the matters complained of were each published after the Mainline system had undergone all of the testing identified in evidence, and had received passes in relation to all relevant standards.
108Although the Defendant did not advance any detailed argument in closing submissions, it is appropriate that I refer to some of the matters taken up by him in cross-examination of Mr Andrews and express my conclusions with respect to them.
109The Defendant suggested to Mr Andrews that the entire Mainline system had not been tested as an entity. Mr Andrews disagreed with that proposition and referred to a number of documents which indicated that the entire system had been tested (T111, T121, T194). I accept the evidence of Mr Andrews that the evidence concerning testing of the Mainline system demonstrates testing of the whole system. The Defendant has not demonstrated any gap or failure in this respect.
110The Defendant raised issues concerning PDC's installation manual. Mr Andrews explained the development of the installation manual through various updates (Exhibits AA, BB, CC; Exhibits 4, 5). His evidence explained this process in a rational way, which did not support any of the safety concerns raised by the Defendant.
111With respect to the cross-examination by the Defendant of Mr Andrews concerning temperature rise and potential for fire, Mr Andrews gave evidence, which I accept, that the system has been tested in accordance with appropriate standards to guard against fire (T136, T183).
112During the course of a lengthy cross-examination, Mr Andrews, at times, sought to respond to some of the Defendant's questions by way of a general response that the Mainline system complied with all relevant standards and had been tested and had passed relevant tests. Although at times this general response did not address directly the specific issue raised in the question, I am satisfied that Mr Andrews responded in a realistic way.
113The evidence reveals the existence of detailed Australian and international standards with respect to a system of this type, and that PDC has taken substantial steps to ensure that the Mainline system complies with all relevant standards. Testing had been carried out and, certainly by the time of publication of the first matter complained of in August 2009, there were no outstanding steps which PDC needed to take to satisfy relevant authorities that the Mainline system complied with all applicable standards. This is an important point given that the Defendant took it upon himself to publish the first matter complained of in August 2009.
Evidence of Mr Carmody
114Mr Carmody prepared an expert report dated 27 May 2010 (Exhibit D). He is a retired senior lecturer in electrical and computer systems engineering at the University of Technology, Sydney. He has graduate and post-graduate engineering qualifications and trade qualifications, including as a qualified electrical contractor.
115In his report, Mr Carmody responded to each of the Defendant's allegations in the first matter complained of, and gave his views more specifically in relation to electrical contacts and standards.
116Mr Carmody expressed the view that the Defendant's claims are not factually correct and are largely speculative (Exhibit D, page 22). He expressed the view that the Mainline system does not pose a greater risk than that posed by normal power points commonly found throughout typical Australian domestic premises, and he reaffirmed that view in re-examination (T255). Mr Carmody expressed the view that all electrical contacts will eventually give rise to problems but that, if the Mainline system is used in accordance with its specifications, it would not give rise to additional problems above and beyond those encountered with standard power points (T235). He expressed the view that the Mainline system represented an acceptable trade off between utility and safety in the same way as a conventional power point does (T237).
117In cross-examination, Mr Carmody accepted that if a 10 cent piece was inserted in the groove in the Mainline system, then it might be possible, in the course of attempting to prise the coin out, to come into contact with the active conductor (T252-253). Despite this, Mr Carmody stated in re-examination that the Mainline system did not pose a greater risk than conventional power point systems (T255).
118Mr Carmody was cross-examined concerning the installation of the Mainline system in a kitchen setting and possible risks which might arise from this. He responded that any installation would be a matter for the electrician or electrical contractor, having regard to the particular circumstances of the layout of the kitchen and the requirements of AS3000, which made specific provision concerning the location of power points in places such as kitchens and bathrooms and wherever moisture and chances of electric shock exist (T254). In my view, this is a reasonable approach given the requirement that the electrician or electrical contractor assess the particular layout and circumstances of the room or rooms in which the Mainline system is to be located.
Evidence of Dr Grantham
119Dr Grantham prepared an expert report dated 23 October 2009 (Exhibit E). Dr Grantham has a PhD and BSc with first-class honours in electrical engineering. He has in excess of 45 years' experience in the electrical industry. He is a chartered engineer and a Fellow of the Institution of Engineering and Technology (UK).
120Dr Grantham was asked to comment upon the Defendant's allegations about the Mainline system in the first matter complained of. He concluded that the Defendant's allegations were alarmist, unsubstantiated and did not represent a balanced view of the Mainline system.
121In cross-examination, Dr Grantham acknowledged that a problem might arise with connection of the Mainline system if it was carried out by a "really ham-fisted" electrician (T208.18). In re-examination, Dr Grantham said that perils arising from acts of a "ham-fisted electrician" , who may act incompetently, could also cause similar perils to arise from the installation of conventional power systems (T223).
122In cross-examination, Dr Grantham expressed the view that the conductor was fixed and that it was part of a fixed installation (T212).
123At the request of the Defendant during cross-examination, Dr Grantham was able to insert part of a flat metal bottle opener (Exhibit 15) into the sample of Mainline track (Exhibit N) (T221-222).
124In re-examination, Dr Grantham acknowledged that there were risks that items such as a pin or an unfolded paperclip could be inserted into a conventional power point giving rise to a risk of shock, but that the existence of that risk involved an acceptable trade off between the risk of shock and fire and the need for the supply of power to people in their everyday life. He agreed that the Mainline system involved a similarly acceptable trade off between the need to ensure safety and the need to provide accessible power to people in their ordinary life (T224).
125In further cross-examination by leave, Dr Grantham pointed to possible safety issues with respect to standard power points and the Mainline system, including the greater visibility of a standard power point, and associated with the risk of insertion of items by children into it, and he acknowledged that the use of a metal object to try and remove a 10 cent coin from the groove in the Mainline system might give rise to a risk of touching the active element. Dr Grantham observed that it was "similar if someone used a fork in an attempt to remove toast, a piece of bread from a toaster, that also could touch the active conductor" (T225-227).
126I observe that the various experiments carried out in Court (at the request of the Defendant), involving insertion of a coin or a flat bottle opener into the Mainline product, utilised a short section of track (Exhibit N). It should immediately be observed that insertion of items into that section does not, in my view, provide particular assistance to the Defendant. When used in practice, the Mainline product is fixed to the wall with corner connectors, which would give the track additional rigidity. I accept the Plaintiffs' submission that this impacted significantly upon the use that could be made of these in-Court demonstrations.
127The Plaintiffs submit that, in any event, the possibility of a person of any age mischievously inserting a metal object, such as a paper clip, hairpin or wire into a conventional power point is one of those risks which is inherent in the use of electricity. Dr Grantham noted in evidence that a standard power point is more visible to a child and more likely to attract a child's attention than the Mainline system (T225). I accept the Plaintiffs' submissions in this respect.
The Defendant's Evidence
128The substance of the Defendant's case emanated from his own evidence. Mr Smark SC made a number of submissions concerning the weight to be attached to the Defendant's evidence and it is appropriate that I express my conclusions on that aspect.
129The evidence reveals that the Defendant has no tertiary qualifications. He left school after Year 10 and worked for a period as a carpenter. He has no formal training or qualifications in electrical engineering, nor as an electrician.
130That said, the Defendant has immersed himself for some years in the field of invention with respect to Power Track-type systems. In 1997 and 1998, he received awards for activities in this field (Exhibits 22, 23). The Defendant was nominated as the inventor in the provisional patent application dated 18 December 2002 with respect to the system which is now the Mainline system (Exhibit H), and was nominated as one of four inventors with respect to that process in the standard patent application dated 18 December 2003 (Exhibit K).
131It may be seen that all of these matters equipped the Defendant to give admissible opinion evidence with respect to safety issues in the case. The Defendant prepared a report dated 12 June 2010 entitled "Mainline Power Track System Safety Report" (Exhibits 3, 3A) which was admitted in the proceedings. The Plaintiffs did not object to the tender of that report, but submitted that limited weight could be attached to it because of the Defendant's limited expertise (certainly in contrast to Dr Grantham and Mr Carmody) and because the Defendant is not independent.
132The ability to give admissible expert opinion evidence does not depend upon the holding of relevant tertiary qualifications. Section 79(1) Evidence Act 1995 provides that if a person has specialised knowledge based on the person's training, study or experience, then the person may give opinion evidence that is wholly or substantially based on that knowledge. It may be said that the Defendant has acquired specialised knowledge as a result of his experience. The Defendant has emphasised that feature during the course of the hearing. However, that is only one aspect of the matter.
133Dr Grantham and Mr Carmody have tertiary qualifications in electrical engineering and have taught for significant periods in that field, as well as acting as consultants and providing opinions with respect to issues in that field. The areas under consideration in this case include not just the practical features of the Mainline system, but the broader concept of functional electrical safety, the nature and effect of relevant safety standards which apply to such a system and electrical engineering issues bearing upon all these aspects.
134Although the Defendant has the advantage of a longer history of involvement with the development of such systems, his ability to give expert opinion evidence on broader electrical safety and electrical engineering issues was limited. That is not to say his opinions ought be given no weight. The Defendant's report of 12 June 2010 constituted, in reality, the high point of his case to make out the defence of justification with respect to the safety allegations.
135This brings me to a significant factor which impacts upon the weight to be given to the Defendant's report and evidence. The Defendant is not an independent expert witness. He is, of course, a party to the proceedings. This does not mean that he is not able to give admissible opinion evidence: Sydney South West Area Health Service v Stamoulis [2009] NSWCA 153 at [186]-[225].
136It should be kept in mind that the origin of this litigation lies in the making of very strong allegations by the Defendant that the Mainline system is fundamentally unsafe in a number of respects which were said to endanger lives. More than once during the hearing, the Defendant said that he published these matters so that he would be taken to Court and would have an opportunity to prove the unsafe nature of the Mainline system. Under cross-examination, he readily acknowledged that he had taunted or threatened the Plaintiffs in his website and emails so that he would be taken to Court (T398, T403-404, T407).
137When the matter came to hearing, the only evidence which the Defendant had in this respect was his own. He acknowledged, under cross-examination, that his concerns did not appear to have been taken seriously by the various bodies with whom he had raised them (T394-395).
138It cannot be said that the Defendant brought a detached and calm mind to the resolution of the issues in the proceedings. The Defendant himself said that he was "emotional" about the product (T426). It is fair to say that the Defendant appears to be totally convinced as to the correctness of his own position and that he will not entertain any contrary position.
139When a court comes to assess expert opinion evidence, a witness who adopts such an approach provides a troubling foundation for a court to act on. The Defendant was literally an advocate (and a passionate advocate) in his own cause, using strong and colourful language in the matters complained of and at the hearing. He spoke as if the issues he wished to raise were self-evidently correct, expressing a level of irritation when his stance was challenged.
140That said, none of these aspects lead me to disregard the Defendant's evidence. After all, he has considerable practical knowledge of the relevant system and is in a position to express opinions concerning it, arising from his practical experience and knowledge in the field. However, the detached and rational assessment of the issues in the case provided by Dr Grantham and Mr Carmody may be contrasted with the Defendant's inflexible approach to issues in dispute. The Plaintiffs' expert witnesses displayed a balanced and objective approach, consistent with their obligations under the Expert Code of Conduct: Rule 31.23, Schedule 7 Uniform Civil Procedure Rules 2005 .
141I accept the submission of the Plaintiffs that considerable caution must be taken in approaching the Defendant's evidence on these issues, and that it is appropriate to consider the opinion evidence by reference to objectively measurable features, such as compliance of the Mainline system with specified standards, and evidence concerning testing of the system by relevant independent testing laboratories. There is a significant volume of evidence of this type in the proceedings. It must be said that it provides no assistance to the Defendant.
Some Conclusions Concerning the Safety Allegations
142The Defendant has made very strong allegations concerning the safety of the Mainline system, with those allegations accompanied by dramatic headlines and illustrations. The Defendant has not alleged a theoretical risk arising from use of the Mainline system. Rather, his safety allegations involve claims that life-threatening events will certainly occur so that the Mainline system ought not be used in its present form. In my view, there is a very significant gap between the risks or concerns which the Defendant can point to with the Mainline system and the allegations which he makes in that respect.
143In my view, the evidence of Dr Grantham and Mr Carmody concerning possible insertion of items into conventional power points and the Mainline system serves to emphasise the point which the Plaintiffs make in this case. There are risks in the real world with both systems, but the risks are not materially greater with respect to the Mainline system than with a conventional power point.
144Further, safety concerns raised by reference to incompetent installation do not advance the Defendant's case. Incompetent installation can give rise to significant safety hazards in the context of conventional power points as well.
145The difficulty for the Defendant is that the publications in the matters complained of involve strong allegations of grave danger in the Mainline system, which are not supported by the evidence which he has adduced in this case through cross-examination if the Plaintiffs' expert witnesses and in his own evidence.
146The conclusions which I have expressed so far do not assist the Defendant with respect to the defence of justification insofar as the imputations contend that the Mainline system is much more dangerous than conventional electrical wiring systems in various respects. The evidence does not support such a conclusion.
147The topics raised by the Defendant, including those referred to at [97] above, were adequately addressed in the evidence of Mr Andrews, Dr Grantham and Mr Carmody.
148In reality, the Defendant is indissolubly wedded to the proposition that the Mainline system is gravely unsafe and life threatening, even though, in my view, the objective evidence advanced by him to support that proposition simply fails to do so.
149I accept the submission of the Plaintiffs that the evidence reveals that the Mainline system has been properly tested, complies with all relevant standards and does not pose any substantial or unreasonable risk to human safety or health, in any way which is substantially different from the risk posed by conventional power point systems. The evidence of Dr Grantham and Mr Carmody, which I accept, was to this effect.
Evidence of Knowledge of Danger by First and Second Plaintiffs
150The imputations with respect to the first matter complained of go far beyond a claim of a lack of safety. Imputations (b) and (d), with respect to the website publication of August 2009, assert that each of the First and Second Plaintiffs knew that the Mainline system was much more dangerous than conventional electrical wiring systems. There is evidence which is entirely inconsistent with each of Mr Higgins and Mr Sharp having such knowledge. It is appropriate that I refer to it.
151Mr Sharp denied having such knowledge (T269-270). He was not aware of any injury, fire, electric shock or other incident involving the Mainline system (T270). Mr Sharp said that, had any such reports been made, he would, as chairman of the board, have become aware of them. I accept that no such reports were made. This was the evidence of Mr Andrews and each of the First and Second Plaintiffs.
152Mr Sharp gave evidence that the Mainline system was installed in the boardroom of Rex Airlines (of which he was a director), in his apartment, in the workshop at his farm and at the PDC offices (T271). All of this placed Mr Sharp in a position to use the Mainline system. He was in a position to have direct knowledge as to whether there had been any problems with respect to the system. Further, and tellingly, the use in a variety of personal and business settings of the Mainline system by Mr Sharp is entirely inconsistent with him having knowledge or a belief that the system was unsafe, let alone much more dangerous than conventional electrical wiring systems.
153Mr Higgins likewise denied the knowledge as contained in the imputations. He had never been told of any fires, injury, electrocution or property destruction in relation to the product (T286). Tellingly, Mr Higgins had sought to introduce the Mainline system into the schools attended by his own children (T291). He stated that he believed in the product and would not have presented it if he had any doubt about its safety (T291).
154In summary, the evidence of the First and Second Plaintiffs, which I accept, revealed that:
(a) each of them expected that the Mainline system would operate safely and that it complied with all relevant standards;
(b) given the business reputations of each of them concerning safety standards and quality, each expected the Mainline system to comply with all relevant safety standards;
(c) at all relevant times, and certainly in August 2009, each of them believed that the Mainline system was safe, as demonstrated by their own use of the system in personal, family and business settings and a willingness to promote it in circumstances where their own family members may utilise it;
(d) all of this was entirely inconsistent with either of them knowing (or even suspecting) that, as the imputations suggest, the Mainline system was much more dangerous than conventional electrical wiring systems.
155Applying the relevant principles mentioned earlier with respect to the defence of justification (at [90]-[95]), the Defendant has failed to establish the substantial truth of the safety allegations made by him in the first matter complained of.
