41 Conduct is misleading or deceptive if it induces or is capable of inducing error: Parkdale Custom Built Furniture Pty Ltd v Puxu Pty Ltd (1982) 149 CLR 191. Conduct will be likely to mislead or deceive if there is a real or not remote chance or possibility that it will do so even if the chance or possibility is less than 50%: Global Sportsman Pty Ltd v Mirror Newspaper Ltd (1984) 2 FCR 82. Based on the data in the Survey, the representations in the TOSS advertisement were misleading. They were capable of causing the reasonable viewer to fall into error. There was certainly a real chance that reasonable viewers would believe what the advertisement told them: that (health fund rebates aside) they would pay on average more than $114 per pair of prescription glasses at Specsavers than they would during the same period at The Optical Superstore and that, at the former, the average price during the period in question (excluding health fund rebates) was actually $366. The Survey data demonstrates that such a belief would have been false. It showed that customers at The Optical Superstore during the relevant period did not pay $114 less for a pair of prescription glasses than they would if they had shopped at Specsavers and did not pay on average at Specsavers $366 for each pair. On the contrary, the Survey results showed that customers surveyed actually paid more for a single pair of glasses at The Optical Superstore during the period than they would at Specsavers.
42 The Optical Superstore challenged the reliability of the Survey data but, in my view, even if the challenge were well-founded, it cannot undermine Specsavers's case. There was no suggestion that Mr Kornides misrepresented the results of the Survey and the TOSS advertisement did not call into question its reliability. I will return to the challenge to the evidence shortly.
43 Specsavers also relied on evidence from its Financial Analyst, Michael Emmerling, to prove that the average price for a pair of prescription glasses during the relevant period was less than $366. In his affidavit Mr Emmerling said that on 12 August 2010 he interrogated the sales data on the Specsavers server relating to the prices paid by its customers for prescription glasses (inclusive of GST) for all ages in the period between July 2009 to January 2010 ("Total Price"). Mr Emmerling also determined the total number of pairs of prescription glasses sold during that period ("Total Number of Pairs"). To determine the actual average price paid by Specsavers customers per pair of prescription glasses during the period he said he divided the Total Price by the Total Number of Pairs. He gave evidence of the figures derived from this calculation. It was also substantially less than the $366 price The Optical Superstore represented customers paid. Counsel for The Optical Superstore, Mr Robertson, sought to undermine this evidence in two ways. In my view, however, he did not succeed.
44 First, he noted that Mr Emmerling's evidence established only that he took a gross sales figure for lenses, frames and coats and divided that figure by the number of frames sold which, he submitted, is not the same as establishing an average price for a pair of prescription glasses. But, as Mr Studdy pointed out, there were problems with the attack on the evidence. In the first place, no challenge was made to the witness's methodology, so the witness had no opportunity to deal with it. In the circumstances, the principles in Browne v Dunn (1893) 6 R 67 (HL) would ordinarily preclude The Optical Superstore from making the submission. In any event, Mr Studdy showed that the inclusion of sales of lenses would only have the effect of overstating the average price. If anything, therefore, Mr Emmerling erred in favour of The Optical Superstore. As Mr Studdy explained:
Simple maths demonstrates that the inclusion by Mr Emmerling of sales of lenses alone can only have had the effect of resulting in a higher average price in his calculation than would have been the case if he had excluded sales of lenses alone. A simple example is as follows. Assume there are 3 sales:
a) Sale 1: customer purchased a frame and a set of lenses total price $250
b) Sale 2: customer purchased 2 frames and 2 sets of lenses and 2 coats $375
c) Sale 3: customer purchased just a set of lenses at $150.
The total amount paid is $775. Based on Mr Emmerling's evidence that entire total would have gone into the numerator in his calculation (this is consistent with the Respondent's submissions). But Mr Emmerling says that he then divided by the number of frames sold across the total transactions. In this simple example, the total number of frames sold was 3. Taking the total sale price and dividing by the number of frames then produces an average of $258.33. If however Sale 3 had been excluded from the calculation altogether (as the Respondent submits it should have been) the total sale price would have been $625. There were still 3 frames sold. Taking the total sale price and dividing by the number of frames sold produces an average of $208.33. Consequently, if anything Mr Emmerling has stated a higher average per pair of frames than was the case.
45 Mr Robertson also emphasised that Mr Emmerling's evidence was that the average price to which he was referring was the average price for customers of all ages whereas the advertisement was concerned with the prices for customers aged 18 and over and there is no evidence about the effect of the discrepancy. These criticisms, in my view, are well founded. I cannot be confident that the figure nominated by Mr Emmerling is in fact the average price paid by Specsavers's customers for a pair of prescription glasses during the relevant period. But the evidence has some value. It seems to me to be unlikely that children's glasses would be more expensive than adult's so that it is unlikely that the prices would increase by factoring in the prices paid for children's glasses.
46 I return to the challenge to the Survey evidence. Mr Robertson's criticism of the Survey evidence was put in this way:
The Roy Morgan survey evidence does not establish the average price of Specsavers. No valid statistical inference can be drawn from it unless the sample was random nor can any inference [scil.] be drawn about standard error or confidence unless the population from which the sample was taken has a normal distribution with respect to the relevant characteristic (Mr Kornides T43). In fact, the sample was not randomly chosen, depending, as it did, on persons selected by some unknown means by one of two sample supply companies (T44-45) deciding whether or not to answer the survey (T44). In addition, the respondents to the survey were limited to e-mail users (T45). There is no evidence that the distribution of spectacle users in the Australian population is a normal distribution.
47 I do not accept the submission. Mr Kornides did agree that for a survey of a sample of a population to produce statistically valid results it is necessary that the sample be random. But Mr Kornides's evidence was that the survey was conducted on the basis of a random selection. Neither he nor Specsavers selected the respondents. He said another company chose the sample and it was up to the respondents to reply to the survey questions. He did not say that this kind of self-selection was not random selection for statistical purposes. And, as Mr Studdy pointed out in his submissions, such a survey was no less random than a survey conducted on the street or by telephone where a random member of the public chooses whether or not to participate. Mr Kornides did concede that, because the survey was conducted by email, it was possible that some people might be excluded from participating by reason of age or poverty and others, who gave partial or non-responsive answers, would also be excluded. But, as I understood his evidence, the process of weighting the survey results, that is, adjusting them according to the distribution of people on the bases of age, gender and region is designed to correct for this. Mr Kornides said that Roy Morgan conducted a survey in 2008 across a representative sample of Australians aged 18 and over to determine what proportions of the population wore glasses and had actually purchased glasses in the previous six months. In re-examination he said that Roy Morgan used those proportions to determine the target number of interviews for the demographic criteria of age, gender and region for the 2010 survey to ensure that the appropriate number of older people, for example, were interviewed. The Optical Superstore called no evidence from a suitably qualified expert to challenge the methodology used to conduct the Survey or Mr Kornides's interpretation of the Survey results. Whilst there will always be difficulties with survey evidence, if this survey or Mr Kornides's interpretation of it were unreliable I would expect to have heard expert evidence to that effect. In fact, the evidence The Optical Superstore called about the average price of its own prescription glasses during the relevant period taken from its computer records was sufficiently close to the figures disclosed in the Survey to give me some confidence in the reliability of its results. More importantly, however, as I said earlier, for the purpose of its advertisement, The Optical Superstore accepted the representations made in the Specsavers advertisement including that they were based on the Survey.
48 Criticisms were also levelled at the reliability of the responses given by Survey participants as the Survey covered a six-month period and because of the potentially confounding issue of health fund rebates. The criticisms fell flat. The Survey participants were asked when they purchased their last pair of prescription glasses. The relevant period was July 2009 to January 2010. Therefore not all respondents were being asked to cast their minds back six months. In some cases the Survey participants may have purchased prescription glasses the day before. Moreover, Mr Kornides said that in his experience with research in this particular category (the purchase of spectacles) people tend to recall the actual price. He also said that the majority of Survey participants specified the precise dollar amounts of their purchases. This supports the inference that, for the most part, the Survey participants probably consulted their receipts before responding. Mr Robertson also raised the spectre that the prices quoted could reflect the prices after health fund rebates. But the Survey participants were specifically asked to select the total cost of their last purchase of glasses before any health fund rebate. And Mr Kornides said that in his experience survey respondents tend to recall the actual price they agreed to pay and regard a rebate from a private health insurer like a bonus when they get it back. There is no reason for me not to accept this evidence. No challenge was levelled at Mr Kornides's experience.
49 The TOSS advertisement began uncontroversially. The trouble starts at frame 3. The comparison in frame 3 purports to reproduce a frame from the Specsavers advertisement. In fact, however, it distorts it. This is frame 3 of the Specsavers advertisement:
50 This is frame 3 of the TOSS advertisement.
51 There are three differences. One is the inclusion of the word "customers". Although Specsavers tried to make something of this, I cannot see it matters. The second is the inclusion of the words "than OPSM customers", which is certainly inconsequential. But the third difference I think is significant. The third difference is that the words "paid over" are reduced to lower case in The TOSS advertisement, potentially reducing their impact on the viewer. In addition, the voiceover omits the preposition "over" when making the comparison with the prices offered at The Optical Superstore. The tone of the announcer's voice also changes at this point. It is louder and more emphatic. This prepares the viewer for what is to come in frame 5.
52 As the advertisement proceeds, it tricks the viewer into thinking that Specsavers's price was in fact the mathematical difference between $480 and $114 or $366. This was convenient for The Optical Superstore. If the average price customers paid at Specsavers for a single pair of prescription glasses during the relevant period were $366, then the difference between that sum and the average price of its prescription glasses rounded to the nearest dollar was $114. But - whatever the uncertainties about Specsavers's prices - I am well satisfied that the average price during the relevant period was not $366 and that Specsavers did not make any such representation.
53 I am also satisfied that frame 5 is overtly misleading. It represents a sleight of hand in that the word "over" - present in the earlier frames - has been removed. It tricks the viewer into thinking that the preposition is redundant. The plain intention is to have customers think that at Specsavers the average price per pair of prescription glasses was $366. Ms Douglas admitted as much. Ms Douglas may have proceeded in good faith but there may be a contravention of the relevant sections of the Act although there is no intention to mislead: Hornsby Building Information Centre Pty Ltd v Sydney Building Information Centre Ltd (1978) 140 CLR 216 at 228.
54 The deception is complete when read with the so-called disclaimer. On the case The Optical Superstore presented, no comparison was made in the advertisement between its prices and those offered by Specsavers. The comparison was between an assumed price of $366, purportedly derived from the Specsavers advertisement, said to be based on the Survey results, and The Optical Superstore's actual average price. Mr Robertson supported this argument with the proposition that the TOSS advertisement was really a commentary on the Specsavers advertisement. A reasonable viewer, he argued, would not expect The Optical Superstore to know the average price offered by its competitors and "would find natural the stated reliance for the Specsavers (and OPSM) price data on Specsavers own advertised survey results". I disagree. The TOSS advertisement, itself, stated that the price differentials shown in frame 4 were based on price comparison based on sales. It also referred to the Roy Morgan survey data. The reasonable viewer would have no idea who commissioned the research, where the data had been published or to whom. They were not "Specsavers own advertised survey results". They were Roy Morgan's. Roy Morgan is an independent company. A reasonable viewer might readily conclude that The Optical Superstore had access to the results of the Survey. Both the reference to the Survey in frame 4 and the unqualified representation in frame 5 that the price comparison was based on actual sales would suggest to the reasonable viewer that The Optical Superstore knew the average prices. What is more, no attempt is made in frame 5 to distinguish between the sources of information for the prices offered by the two businesses. In any case, why wouldn't the viewer reasonably believe that the actual prices were the same as the prices disclosed in the Survey?
55 Mr Robertson submitted that the prepositions used in the advertisement were designed to show that the figures were approximate but only in so far as they rounded off the price to the nearest dollar. This was the position Ms Douglas had taken in cross-examination. Mr Robertson said:
The assertion in the Optical Superstore's TVC about the price differential between itself and Specsavers was an assertion that the difference was $114 and some cents.
Similarly, the assertion in the Specsavers' TVC about the price differential between itself and OPSM was an assertion that the difference was $114 and some cents, being $114 and some cents less than a number being something over $480. Thus the Specsavers' TVC was asserting, by stating the OPSM price of (over) $480 and the price differential of $114 and some cents, that its own average price was $366.
56 I reject the submission. In my opinion, the reasonable viewer would not expect to see "over $114 less" if the true price were $114 and some cents less. In context, in its ordinary meaning "over" simply means "higher or more than". If the figures shown were rounded off to the nearest dollar, the viewer would expect to see a disclaimer to that effect. Indeed, in frame 4 The Optical Superstore's disclaimer actually stated that the average was rounded to the nearest dollar whereas the Specsavers advertisements made no such representation.
57 I am satisfied that the two representations were misleading or deceptive or likely to mislead or deceive and Specsavers has made out its case that the TOSS advertisement contravenes both ss 52 and 53(e) of the Act.
