The evidence
48 Save for appending to the amended statement of claim the order made by Ryan J on 6 April 1993, the applicant made no attempt to prove the facts alleged in pars 40 to 44. An examination of the order of Ryan J discloses that, in order to be comprehensible, it requires resort to be had to documents filed in the proceeding in which it was made. In particular, the order includes an order that there be judgment for the applicant for final injunctions in the terms of pars 13 and 14 of the application in that proceeding. The application is not in evidence in this proceeding. I must therefore disregard pars 40 to 44 of the amended statement of claim in this proceeding, as the allegations in them have not been proved.
49 In relation to the proceeding referred to in pars 45 - 53 of the amended statement of claim, the applicant attached the order made by Goldberg J on 3 November 1997. That order is at least specific as to the terms of the injunction his Honour granted. It is therefore established that such an order was made by consent in that proceeding. In order to make good the rest of the allegations made in pars 45 - 53 of the amended statement of claim, the applicant, with the consent of the respondent, tendered in this proceeding some material that was filed in the earlier proceeding involving Jayco Pty Ltd. The material consists of three affidavits. An affidavit of Mark Lawrence Wahlqvist, affirmed on 6 October 1997, was filed in proceeding number VG567 of 1997 on 7 October 1997. Professor Wahlqvist is a medical expert, eminently qualified in the field of nutrition. A further affidavit of Professor Wahlqvist, affirmed on 30 October 2002, was filed in proceeding number VG567 of 1997 on 31 October 2002, in support of an application to punish the respondent for contempt of court by reason of contraventions of the injunction granted by Goldberg J in proceeding number VG567 of 1997. Also filed in support of that application on 31 October 2002, was an affidavit of Gad Binyamin Ellinson, an officer of the applicant, sworn on 29 October 2002.
50 Much of the material contained in the affidavit of Mr Ellinson and the exhibits to it is irrelevant to this proceeding, in the light of the admissions made by the respondent. The affidavit was produced for a purpose other than proving the unadmitted allegations in this proceeding. Among the exhibits to the affidavit, however, is a notice served on the respondent by the applicant, pursuant to s 155(1)(a) and (b) of the Trade Practices Act, seeking answers to written questions and the production of documents and a document containing the respondent's answers to these questions. The notice contains 132 numbered questions, some of which have multiple parts. Significantly for the present proceeding, the notice asked the respondent detailed questions as to the information in his possession substantiating the various representations, and as to the identities of the persons to whom testimonials are attributed in the advertisements. In one of his answers, the respondent referred to 'material regarding the effect of pressure points within the ear upon suppression of hunger.' He claimed that, 'there is a body of material which is successful [sic] via the internet in respect to auriculotherapy, ear acupuncture and acupuncture generally' and gave a reference to an example of such material. He also referred in general terms to material from an organisation which originally produced a product similar to Acu-Slim 2000 in America, with which he claimed to have had dealings in the early to mid 1990s. He described this material as being 'in the form of reports and opinions regarding both issues of pressure points within the ear which effect [sic] hunger and also in respect to the production of the product itself plus testimonial material.' He referred to conversations he claimed to have had with a person called Jean Claude Koven of Original Marketing Inc, who he said originally produced a similar product in America. The conversations related to the existence of pressure points within the ear, affecting hunger and to issues of acupuncture generally and the way in which the product 'operated to access and stimulate the particular pressure points.'
51 The respondent also referred to two specific written testimonials which he said were in his possession, but which he could not locate.
52 In relation to foods that cause weight loss, the respondent claimed that there is a wealth of material accessible via the internet. He gave examples of two sites. He referred to many discussions on dieting and recipes via radio and television, and to general discussion regarding foods which assist in weight loss, including conversations regarding negative calorie foods. As to testimonials on this subject, he claimed to have taken them from an American publication in the early to mid 1990s. When asked to list 19 foods causing weight loss by burning more calories than they contributed, he listed 32 different foods and claimed that there are more than 19 foods that qualify as negative calorie products.
53 Also among the material exhibited to the affidavit of Mr Ellinson filed in the earlier proceeding is an exchange of correspondence, consisting of a letter from the applicant to the respondent dated 27 May 2002, and the respondent's reply dated 31 May 2002. The applicant's letter contained the following allegation:
'As you may recall, in 1997 the Australian Competition and Consumer Commission ("ACCC") instituted proceedings against you in respect of your involvement in the distribution of virtually identical material as the enclosed material. The ACCC alleged in those proceedings and continues to maintain that the claims and representations made in the material concerning the weight loss that can be achieved by use of ThermoSlim cannot be substantiated.'
54 The letter contained a number of questions, directed to the respondent. One such question requested:
'the reason you recommenced promoting ThermoSlim despite the previous action taken against you by the ACCC in respect of your previous involvement in the promotion of the product'.
55 In response, the respondent did not admit distinctly that the earlier proceeding involved the distribution of virtually identical material. Indeed, in answer to the question quoted above, he said:
'I was under the impression that it was Easy Trim that was banned, and not Thermoslim. It had been just over seven years since the court case and I had become confused. I apologise for this error.'
56 My purpose in referring to this material is not to suggest that the respondent's statements should be believed. The material supplied by the respondent in response to the questionnaire is relevant in three ways. First, it makes clear that the respondent has not admitted the allegation of republication of material relating to ThermoSlim, identical to that published in the Jayco case, pleaded in pars 46(b)(i) and 50 of the amended statement of claim. Second, it goes to the question of extent to which the falsity of the advertisements the subject of this proceeding has been established by other evidence. Third, it goes to the issue of the state of mind of the respondent in relation to the Vesk and Pepin advertisements, in which his knowledge of falsity is relevant.
57 To ascertain whether the allegations of publication of identical material have been proved, it is necessary to make a comparison between the advertisements, publication of which is admitted in the present proceeding, which are exhibited to Mr Ellinson's affidavit filed in the earlier proceeding, and some of the exhibits to the first affidavit of Professor Wahlqvist, filed in the earlier proceeding. It is then necessary to make a judgment as to whether the advertisements, the publication of which is admitted in the present proceeding, are 'identical to, other than for minor variations' the earlier advertisements.
58 An examination of an earlier advertisement for a device called 'ACU-STOP 500' shows that it is identical in every respect with the copy advertisement for 'ACU-SLIM 2000' the subject of this proceeding, with the exception of the name of the product, the name, address and telephone numbers of the marketing business, and the extent of weight loss claimed in respect of one of the testimonials. In addition, the words '(Original Testimonials held on file)' appear on the earlier advertisement. The variations between the 'Foods That Cause Weight Loss' advertisement, the subject of par 20 of the amended statement of claim, and an earlier advertisement for 'The Twelve Foods That Cause Weight Loss: The Cal-Burn Principle' are much greater. Perhaps most obviously, the earlier advertisement relates to 12 foods that are said to help in weight loss, whereas the advertisement the subject of the present proceeding refers to 19 such foods. It is fair to say, however, that the representations alleged in pars 10 and 20 of the amended statement of claim are similar to those that emerge from the earlier advertisement. The material relating to ThermoSlim appears to be almost identical to the equivalent material the subject of the earlier proceeding, with the exception of changes of the name, address and telephone numbers of the supplier. Perhaps significantly, two identical testimonials (save for a change from using 'pounds' to using 'kilos'), with two identical photographs, are attributed to two different people as between the two advertisements. By means of this material, therefore, it can be said that the applicant has succeeded in establishing the allegations in pars 48, 49 and 50 of the amended statement of claim.
59 The falsity of the advertisements is the next issue. Between Professor Wahlqvist's second affidavit and his first affidavit, there is a considerable amount of repetition. The second affidavit was filed in the Jayco proceeding, in support of the application that the respondent be dealt with for contempt of court in that proceeding. It therefore relates specifically to the three sets of advertisements that are the subject of this proceeding. Professor Wahlqvist expresses opinions in general terms about an area of his specialisation, namely the treatment of obesity, including weight loss techniques, before expressing particular opinions about the sets of advertisements the subject of the present proceeding. I summarise his views as follows.
60 The principal way for a person to lose body fat is by the creation of an energy deficit, when the level of energy used by the body exceeds the level of energy taken in the form of calories contained in food consumed. This results in some of the body's fat deposits being transformed into energy to meet the deficit. There are two principal ways of creating an energy deficit. One is to restrict energy intake, ie eating food with lower overall number of calories. The other is to increase energy expenditure, usually by way of physical activity. A third method is altering the efficiency with which energy is used by the body. This may be achieved by increasing the body tissue which requires energy. The greater the muscle mass, the higher the basal metabolic rate. The body stores energy as fat and carbohydrates in a form known as glycogen. The fat and carbohydrate are ultimately converted into adenosine triphosphate (ATP) as the final common pathway for delivery of energy for the basic functions of life and for tissue maintenance and movement. The metabolic rate is the rate at which ATP stores within the body are used up. It includes hormonal profiles or other chemical regulators. For example, the thyroid hormones produced in the thyroid gland at the root of the neck are transported to the body's tissue via the bloodstream and speed up tissue metabolism. Restriction of food intake has the result that, in the first few days there is a loss of glycogen stores in the liver and muscle. Most of the weight loss in this period would be loss of fluid and not of significant amounts of fat. It is necessary to use 'up to approximately 500 calories per day' in excess of normal calorie expenditure for a period of two weeks to achieve 1 kilogram of fat loss. Even with a combined program of energy intake restriction and increased physical activity, it would be most exceptional to use more than 1.5 kilograms of fat per week or 6 kilograms per month. Greater body fat losses than 1.5 kilograms per week are unrealistic and certainly unsafe because of the adverse nutritional consequences on the body. Such losses would be akin to an illness involving vomiting or diarrhoea, or to diabetes.
61 Professor Wahlqvist is aware of no published scientific data to show that acupuncture, or its derivatives by way of oral devices, are effective in humans in appetite suppression or weight management. He has worked with hospitals in China which have expertise in traditional Chinese medicines. In those centres, acupuncture as a treatment for weight loss is 'relatively undeveloped'. This is not surprising as acupuncture was developed in a society where obesity has rarely been a problem. The claim that Acu-Slim can cause a person to lose up to 10 kilos in 30 days, without illness, is in Professor Wahlqvist's opinion completely unsupported by any scientific substantiation. The testimonials set out in the Acu-Slim material are not credible and could not represent the typical or ordinary experience of users of the product.
62 The concept of foods containing 'negative calories' is spurious. Calories measure energy and all calories are equal. There are no foods containing particular types of calories which are different in nature from calories in other foods. It is part of conventional weight management to employ foods having low calorific values for the purpose of allowing people to reach satiety without excessive calorific intake. There is no scientific evidence that the consumption of such foods causes weight loss by burning more calories than the foods contribute to the body, or that the more of these foods a person eats, the more weight will be lost. There is scientific evidence that certain foods have properties that minimise weight gain. For example, it is possible to reduce the body's absorption of nutrients which provide energy by inhibition of digestic enzymes. For example, soy has components which inhibit the enzymes which digest protein. There are dietary fibres which bind nutrients and prevent their absorption. Some components of foods, such as lectins found in certain beans, can induce malabsorption by damaging the intestinal lining. It is possible in this way to reduce the effectiveness of the body absorbing food and thereby reduce the amount of fat stored. It would be false to represent about these foods that they contain negative calories. There is no scientific evidence that these foods cause weight loss by burning more calories than they contribute to the body or that the more of them a person eats, the more weight would be lost. There is no scientific evidence that persons can achieve weight loss by the consumption of any food when added to their diet. In Professor Wahlqvist's opinion, there is no scientific evidence to support the claims that any foods contain negative calories, that the consumption of foods causes weight loss by burning more calories than the foods contribute to the person consuming them or that the more of those foods a person eats, the more weight will be lost. The testimonials set out in the advertisement are not credible and could not represent the typical or ordinary experience of users of that weight loss method.
63 Thermogenesis is the generation of heat from energy stores, such as fat or glycogen, ie the conversion of calories into heat. It can be a method of 'wasting' energy, rather than using energy stores for the body's normal functions. This is not entirely waste because heat is required to maintain core body temperature. Thermogenesis, over and above that which occurs through basal metabolism, normally occurs from activity, including exercise, from eating, in which a proportion of the calories consumed is expended as heat through the activity of consumption, and through shivering. It is possible to affect thermogenesis through diet and drugs.
64 In relation to diet, the thermogenic effect of consuming a particular food will depend upon the presence and amount of macro nutrients (protein, carbohydrates, fat and alcohol) in the food and the extent to which the food stimulates the body's rate of metabolism. Diet-induced thermogenesis generally accounts for only a small proportion of the average person's energy expenditure, perhaps 200 calories each day or up to 10 per cent of intake. This is a negligible amount and achieving an energy deficit of this amount would have a minimal effect on weight. Greater thermogenic effect will be achieved if food with more protein, carbohydrates or alcohol, as opposed to fat, is consumed. The consumption of foods containing protein, carbohydrates or alcohol cannot cause loss of body weight because the energy input arising from the consumption of those foods will always exceed the energy expenditure caused by thermogenesis arising from the consumption of the foods. Only about four types of foods have been identified as having a significant thermogenic affect, such that their consumption can cause a significant increase in the body's metabolic rate. These include chilli, mustard, red pepper and coffee. There is no scientific evidence that the consumption of any of those foods can cause weight loss.
65 In relation to drugs, if the thyroid hormone level in the blood is altered by ingesting thyroid hormones, or by the thyroid gland making more thyroid hormones, thermogenesis will occur. If a person is deficient in iodine, the thyroid gland does not make an adequate amount of thyroid hormone. Replenishing iodine stores will allow the body to make more. Increasing iodine intake over the norm will not increase the production of thyroid hormones further. Because of the mixed diet enjoyed by most Australians, iodine deficiency is extremely rare in this country. It is unsafe to the human body to consume food containing thyroid hormones and it is outside medical practice for a medical practitioner to prescribe food containing thyroid hormones, irrespective of the patient's medical condition. Even if the ThermoSlim wafer contained iodine, it would not be effective as a weight loss product for the vast majority of Australians. If it contained thyroid hormones, it would be medically unsafe to consume.
66 In Professor Wahlqvist's opinion, the endorsements and testimonials in the ThermoSlim material could not possibly represent the typical or ordinary experience of people who have consumed ThermoSlim wafers. The only way by which a weight loss of 2 kilograms in the first 72 hours could occur is through a loss of body fluid, not fat. In any event, extrapolations based on the first week of weight loss in any program are misleading in so far as they suggest any change in body fat and in so far as they suggest that such a dramatic weight loss could be continued at the same rate. While people normally fluctuate by up to 1 kilogram in the course of 24 hours, a weight loss of 10 kilograms in the first month, or any weight loss, could not be brought about by the eating of wafers such as ThermoSlim, regardless of their precise composition, unless they were heavily medicated with diuretics, which would induce fluid loss, or thyroid hormone, or iodine where the person had an iodine-related deficiency. In Professor Wahlqvist's opinion, the ThermoSlim wafer does not represent a breakthrough in weight management in any sense. He is aware of no scientific substantiation for the weight loss claims made in the ThermoSlim material. Despite his involvement in national and international nutritional affairs, and his awareness of nutrition institutes and authorities around the world, he has never heard of the person whose opinion was included in the ThermoSlim material.
67 The evidence of Professor Wahlqvist is unchallenged and is not inherently incredible. It tends to prove the falsity of each of the representations pleaded in pars 8, 10, 20 and 32 of the amended statement of claim. It does not always express the negative propositions pleaded in pars 9, 11, 21 and 33 of the amended statement of claim in such absolute terms as they are pleaded. Perhaps more importantly, it does not attempt to grapple with the standard qualified admission in the respondent's pleading, particularly the assertion of the existence of some scientific evidence regarding the merit of the various products. Although Professor Wahlqvist's second affidavit was affirmed more than 11 months after the respondent provided to the applicant information in response to the notice pursuant to s 155 of the Trade Practices Act, Professor Wahlqvist makes no attempt to deal with the respondent's assertions in some of those answers. In particular, where the respondent has referred to identified websites as containing information, Professor Wahlqvist has not been asked to ascertain what information is available on those websites and to state his opinion in respect of such information. Although there is no doubting the eminence of Professor Wahlqvist in his field, there is no indication in either of his affidavits as to whether his views represent a scientific orthodoxy which is subject to challenge and, if so, the source and nature of the challenge.
68 These deficiencies in the material leave the Court unable to arrive at a clear view of the facts. The applicant has pleaded a number of representations and has pleaded their falsity, usually in absolute terms and in the negative of the representation. The respondent has agreed to consent to orders of the Court on the basis of his pleading, which contains the standard qualified admission. If there should be any doubt that this is the basis on which the respondent has consented, it is removed by the letter from the respondent's solicitors, to which I have referred in [6] above. That letter contained the following:
'Please note our client has filed the attached Amended Defence to Amended Statement of Claim[.] This indicates in substance, that the representations made in respect to the various products were overstated and the testimonials did not reflect the ordinary and typical experiences of persons who use them and on that basis the representations were capable and likely to mislead and deceive.
Our client wishes to resolve the matter promptly and at minium [sic] cost.'
69 The evidence does not enable me to find the negative of each of the representations, as the applicant pleaded. I am left to determine the case on the basis that the representations were misleading and deceptive at least to the extent admitted by the respondent in the standard qualified admission. They may have been misleading and deceptive in other respects, but I cannot determine the degree or nature of their falsity on the evidence before me.
70 The seriousness of the conduct alleged is a matter relevant to the exercise of any discretion whether to make orders against a respondent in a proceeding of this kind. If the Court cannot assess the degree of seriousness, it is hampered in exercising its powers.
71 In this respect, it is also necessary to examine whether the allegations of knowledge in pars 18(b), 19(b), 28(b) and 29(b) of the amended statement of claim have been established. In his letter dated 31 May 2002 to the applicant, from which I have quoted in [55], the respondent's answer to one of the applicant's questions suggested that he was unaware of the precise terms of the injunction granted against him in the Jayco proceeding. The affidavit of Ms Jarvis, filed in the Jayco proceeding, makes it clear that the order of Goldberg J, made on 3 November 1997, was never served personally on the respondent. In seeking to punish the respondent for contempt of court in contravening the order made in the Jayco proceeding, the applicant was forced to rely on the fact that the respondent was present in court when the order was made and that the order was served on his solicitors. Further, there is nothing in the material presently before me that would indicate that the respondent had actual knowledge of the contents of the first affidavit of Professor Wahlqvist, filed in the Jayco proceeding, that being the only expression of Professor Wahlqvist's opinions in existence at the time of the publication of the material the subject of this proceeding. It is worth noting that the material in Professor Wahlqvist's first affidavit was considerably shorter than that in his second, but I have not troubled to ascertain whether it is sufficient to render false all of the representations pleaded in the present proceeding. The point is that, by reason of his solicitors having received the affidavit and the order of Goldberg J, the respondent had the means of knowledge of the matters referred to in the particulars appended to pars 18 and 28 of the amended statement of claim, but there is no evidence that he had actual knowledge of those matters.
72 In relation to some of the allegations in the amended statement of claim that were not admitted by the respondent in his amended defence, the applicant made no attempt at proof. I refer particularly to the allegations in pars 40 - 44 of the amended statement of claim, relating to the earlier proceedings involving Boardchain Pty Ltd, in relation to which the precise terms of earlier injunctions, and in particular whether they bound the respondent, were not apparent from any material before the Court in the present proceeding.
73 The one affidavit filed on behalf of the applicant in the present proceeding does not deal with any of these gaps. It merely deposes to the fact that Pepin was deregistered on 15 December 2002, a fact peripheral to the issues in the present proceeding, as Pepin has never been a party to the proceeding.
