The proceedings before the primary judge
10 Before the primary judge the appellant argued that the respondent had not proved that he had sustained any loss as a result of the appellant's breaches. On the other hand, the respondent claimed damages for the loss of the opportunity to increase the growth of his practice and thereby increase his income as well as for actual loss of income allegedly sustained.
11 The respondent gave evidence that all his patients had to be referred to him by a general practitioner in order for them to be able to recover his fees from Medicare. He distinguished between new initial patients who had not seen him before and old initial patients who had but were to see him for further treatment. He claimed that before February 2000 he was seeing between 10 and 15 new initial patients per week but that after the 2000 Yellow Pages was published in that month, the number of such patients dropped to two or three per week although by February 2001 that number had increased to eight per week and by mid-2001 had returned to their pre-February 2000 level. The number of patients seen by the respondent and the variations from 1999 to 2001 was part of the information given to a firm of accountants, Howarth & Associates. Mr Watt of that firm prepared a report dated 3 October 2002. Accepting the respondent's evidence, it was submitted that on the basis of the Howarth report the respondent's practice either declined or stagnated during the 2000 calendar year and did not regain growth until mid-2001.
12 The respondent also relied upon a survey of his patients which he had conducted from 1 December 2001 to 28 February 2002 to demonstrate the number of patients who used the Yellow Pages for the purpose of contacting him. The primary judge accepted the respondent's submission that the survey established that "some proportion" of his patients obtained details of his address and telephone number by consulting the Yellow Pages.
13 Before the primary judge the appellant submitted that the evidence established that the respondent saw more patients and generated more income after February 2000 compared to prior to that time; that there was no causal connection between patient numbers and the appellant's breaches; and, further, that there was no evidence that the respondent's income would have been any different than it in fact was, even if the omitted line item entries had appeared. The appellant further submitted that if, as the respondent suggested, all his patients were referred to him by a general practitioner, then there was no evidence that the referring general practitioners were unaware of his change of name so that any patients who were referred to him, but who were unable to find his address and telephone number in the Yellow Pages, could have checked with their referring general practitioner or Directory Assistance.
14 Although the respondent gave evidence that there was a drastic drop in the number of patients seen by him in 2000 which reached its lowest point in or about March/April 2000 thus leaving a hole in his practice which was not filled, he ultimately agreed that from 1999 to 2001 the annual income of his practice rose significantly and improved from year to year. As a result of that evidence the primary judge found (at [16]) that the respondent could not establish any specific financial loss resulting from the appellant's breaches. Accordingly, damages could only be assessed on the basis of a loss of a chance or opportunity.
15 The respondent was cross-examined with respect to his assertion that his practice declined after February 2000 (that being the basis upon which the Howarth report had been prepared). As a consequence of that cross-examination, the primary judge concluded (at [18]) that the respondent was incorrect in his recollection that his practice had declined due to the failure of the appellant to provide the contracted line item entries in the 2000 and 2001 Yellow Pages. He therefore rejected the Howarth report as based upon unsubstantiated statistics. Furthermore, his Honour (at [21]) rejected the assumption made by Mr Watt in the Howarth report as to the likelihood of the numbers of persons not being able to locate the respondent because of the absence of the relevant entries in the Yellow Pages although he did accept that "some persons" might not have been able to locate the respondent by that means. That finding, his Honour said, was consistent with the respondent's survey to which reference has already been made.
16 His Honour also rejected (at [21]) as "inherently improbable and unrealistic" the assumption made by Mr Watt that all of those patients of the respondent who did not find his details in the Yellow Pages had no knowledge of any alternative method of obtaining those details. However, his Honour also held (at [30]) that it was a reasonable assumption that an unspecified number of patients may not have been able to obtain those details despite the fact that there were alternative means of doing so.
17 The primary judge accepted (at [24]) that there was no reduction in the number of patients the respondent saw during the period in question and that there was no identifiable reduction leading to a loss of income. In addition, his Honour accepted that the respondent had not proved any causal connection between any alleged specific changes in patient numbers and the breaches relied upon. In particular, his Honour noted the evidence of the respondent that from March/April 2000 to mid-2001 the number of patients he saw rose dramatically notwithstanding the omission of the subject line item entries.
18 The appellant tendered a report by a Mr Brown of MSM Loss Management dated November 2002. Mr Brown, who was a certified practising accountant, reviewed the taxation returns of the respondent and his company and concluded that there was a basis for an assessment of the respondent's loss in the sum of $10,985. Mr Brown considered that there was lost revenue in 2000, 2001 and 2002 and concluded that this was caused by the failure of the appellant to provide the omitted line item entries. The primary judge accepted (at [26]) Mr Brown's evidence that the respondent had suffered a loss of opportunity to obtain income during the period when the relevant entries were omitted although he was not prepared to accept that the calculations made by Mr Brown based on specific figures should be the basis for the determination of the respondent's damages.
19 In conclusion, the primary judge found (at [27]) that on the balance of probabilities the respondent had lost the opportunity to obtain income from patients who could not locate him because of the omissions from the Yellow Pages. He considered that the relevant principles to be applied were those articulated in the joint judgment of Mason CJ, Dawson, Toohey and Gaudron JJ in Sellars v Adelaide Petroleum NL (1992) 179 CLR 332 where at 349, omitting citations, their Honours said:
"In the realm of contract law, the loss of a chance to win a prize in a competition resulting from breach of the contract to provide the chance is compensable, notwithstanding that, on the balance of probabilities, it is more likely than not that the plaintiff will not win the competition. As the contract contained a promise to provide the chance, the breach of the contract resulted in the loss of the chance and that loss was for relevant purposes an actual loss … And where there has been an actual loss of some sort, the common law does not permit difficulties of estimating a loss in money to defeat an award of damages. The damages will then be ascertained by reference to the degree of probabilities, or possibilities, inherent in the plaintiff's succeeding had the plaintiff been given the chance which the contract promised."
20 The primary judge then continued in these terms:
"28. In my opinion the damages should not be nominal. The plaintiff has lost a commercial advantage by not having his full details available through the Yellow Pages. The defendant's own evidence supported that a commercial advantage would be obtained to a customer by such an advertisement. It follows that the failure to provide such an advertisement deprived the plaintiff of that advantage for which he is entitled to be compensated.
29. Although it is difficult to ascertain the precise degree of loss, some indication of the possible loss suffered can be obtained from the income of the company during the years 1999, 2000, 2001 and 2002. In my opinion it would not be unreasonable as a percentage of the overall income during that period to allow the plaintiff as a loss of opportunity for income a figure of $25,000. This, to my mind, would be a fair assessment on the information available as to such loss."
