GRIFFITHS J:
48 I have had the distinct advantage of reviewing the judgment of Perram J in draft form. I agree with the orders proposed by his Honour and, with one qualification, with his Honour's reasons.
49 The qualification relates to the finding that [1533] of the primary judge's reasons for judgment discloses a legal error in relation to the onus of proof. In my respectful opinion, and for the following reasons, the primary judge made no such error.
50 In my view, [1533] of the primary judge's reasons, together with [1527] and [1528] which are related, need to be read in the context of how the case below was pleaded and conducted. For convenience, I will set out again those paragraphs of his Honour's reasons for judgment:
[1527] However, the applicant also accepted, subject to one matter, that the common law alleged restraint was reasonable when it was imposed, that is, at those dates it was reasonable to prohibit conception by artificial insemination. The applicant submitted that when blood-typing became mandatory in Australia from 1 August 1986, the previous rationale of avoiding deliberate or accidental incorrect paternity had ceased to have any force.
[1528] The "one matter" to which I have referred in the preceding paragraph is that the applicant submitted that the ban on the conception of thoroughbreds by AI should be read as if it was subject to an unexpressed condition or qualification to the effect that the ban should obtain only until there was a scientific method of checking for identity fraud and that that point had been reached by the mid-1980s. I reject that submission as having no foundation in the language of the relevant rules or in the evidence as to future probabilities which could have been foreseen by those affected at the time of the introduction of the ASB provision or at the time of introduction of ARR 15A.
…
[1533] In the present case there was no contemporaneous relevant evidence of future foreseeable probabilities in this respect. Later facts do not relevantly throw light on the circumstances then existing. I reject the applicant's submission that it was always to be expected that tests such as blood-typing and DNA testing would evolve to a point where they would provide a reliable method of verifying pedigree.
51 The reasonableness of the alleged restraint was raised by the ASB Respondents in [40] of their defence and by the ARB in [41C]-[41F] of its defence. It is significant to note that the Appellant below did not raise any issue as to the open-ended duration of the alleged restraint of trade in either the third further amended statement of claim or in any of his replies.
52 Moreover, no reference was made to that issue in either the Appellant's opening or closing addresses at trial. In his closing written outline below, the Appellant argued that, where the alleged restraint is "of greater antiquity" (as the ASB Provisions were said to be based on the Appellant's assertion that they were first imposed in the late 1940s), then:
(a) "It is less clear that grounds which may have justified [the] restraint as reasonable when first imposed, but have ceased to have any relevance, should…continue to rule from the grave"; and
(b) there is a basis for refusing to enforce the restraint "if circumstances afterwards arise in which it would be unreasonable or unfair" to enforce the restraint (see [225] of the Appellant's closing written outline below).
53 It was only in the Appellant's written submissions in reply that the indefinite duration of the alleged restraint was first squarely put in issue. Paragraph 63 of those reply submissions was as follows:
When the restraint on the use of AI, otherwise than by way of reinforcement, was introduced in 1949 (or earlier), the reason was the absence of any effective tests to detect possible fraud or mistaken identity in relation to the recording of new-born foals in the Stud Book. The prohibition on AI, which could not readily be detected, was therefore a reasonable response to the problem at hand and did not more than protect an interest of the proprietors of the Stud Book they were entitled to protect. However a restraint must be reasonable as to its scope, area and temporal dimensions. The restraint when first imposed 60 years ago did not meet the last of these requirements. It was not limited as to time and it was never suggested that it would cease to have effect once an effective test was available. It was always to be expected that tests such as blood-typing and DNA testing would evolve to a point where they would provide a reliable method of verifying pedigree. A restraint which prohibited AI for this reason alone would have been reasonable had it been limited to such period as any reliable physical or scientific test was unavailable and unproven. No other reason appears to have been put forward for the restraint at the time. International comity would not have provided a justification in 1949. In the absence of any temporal limitation of the kind described, the restraint must be judged to have been void ab initio.
(Emphasis added).
54 In his closing oral submissions at trial, the Appellant's Senior Counsel (Mr Tonking SC) elaborated on [63] of the Appellant's written reply submissions. Relevantly, he said:
We say, well, it could have been made in reasonable terms at the outset by being limited in time so as to operate only for such time as there was not some more specific remedy for the problem that was encountered. Something better calculated, without prohibiting artificial insemination, better calculated to deal with issues of identity. And that limitation was never imposed. It was - the rule was introduced in terms which prohibited artificial insemination without limit as to time. (Transcript, 15 December 2011, p 42, l 42 - p 43, l 1-2).
55 In response to a question from the primary judge as to whether the original restraint was being read as if it said something like: "Here is the prohibition (for so long as it's necessary to prevent identity fraud)", Mr Tonking SC responded:
Yes. Until such time as some technology is developed, or some more efficient means of detecting fraud without prohibiting in its entirety a method of conception (Transcript, 15 December 2011, p 43, l 8-10).
56 In his closing oral submissions before the primary judge, Senior Counsel for the ASB Respondents (Mr Bannon SC) paraphrased the Appellant's argument on this issue as involving the proposition that "in relation to the justification of the [restraint] when it first came in, you should now conclude that it was then unreasonable because it in effect didn't predict DNA testing or blood typing testing" (Transcript, 16 December 2011, p 90, l 8-10). Mr Bannon then submitted that the Appellant's argument effectively took into account subsequent events, namely blood typing and DNA testing, to argue that "effectively it should have been predicted and therefore the rules should not have just been no AI; it should have had some other formulation" (Transcript, 16 December 2011, p 90, l 21-24). He then added:
What, until DNA testing comes in or until blood type testing comes in, neither matters which there's any evidence to suggest some - anyone could have reasonably contemplated it, or even some wording like, "until some viable testing method comes in". What does that mean? Is affidavits viable (sic) or whatever? One just asks the relatively simple proposition, is at the time its reasonable (sic), and at the time it was imposed, and that's not the only reason it was brought in…
(Emphasis added).
57 Although the transcript reads a little awkwardly, it is relatively clear that at the core of Mr Bannon's response was the proposition that there was no evidence to support the Appellant's belated assertion that, at the time the restraint was imposed (i.e. 1947), it was expected that future technological developments relating to blood typing and DNA testing would evolve so as to provide a reliable method of verifying pedigree.
58 As the Third Respondent pointed out in its outline of written submissions in the appeal, this means that it was not until after the close of evidence that the respondents were made aware of there being any question in the litigation as to what may or may not have been reasonably foreseeable when the prohibition on the inclusion of horses produced by AI was first inserted into the ASB Rules. And as the Third Respondent further pointed out in its outline in the appeal, if an issue relating to the open-ended nature of the alleged restraint was to be litigated, it should have been raised by the Appellant below in either his pleadings or in opening or, at the very least, by adducing evidence which the respondents would have had to answer in order to demonstrate that it was not reasonably foreseeable in the late 1940s that technological developments might in the future provide a solution to the parentage identification problem and that, consequently, the indefinite nature of the prohibition of including AI horses in the ASB was reasonable.
59 In these circumstances, even though the respondents carried the legal onus of proving circumstances supporting the reasonableness of the alleged restraints, the Appellant's conduct of the trial in relation to the issue of the foreseeability of technological improvements gave rise to an evidentiary burden on his part to demonstrate that there was sufficient evidence to raise a question as to the existence or non-existence of a fact in issue. No such evidence was adduced by the Appellant.
60 When the primary judge expressly rejected the Appellant's submissions in [1528] and [1533], I do not consider that his Honour was reversing the legal onus of proof. Instead, as the ARB submitted in the appeal, his Honour was merely responding to the circumstances that the Appellant had:
(a) conceded that a prohibition on the inclusion of AI horses was a reasonable response to the parental identification problem as at the late 1940s; and
(b) not previously raised any issue concerning the foreseeability of technological developments that might have afforded a less drastic solution to that problem.
61 Given those circumstances, his Honour was doing no more than rejecting the Appellant's belated and unpleaded assertion that such developments were "always to be expected".
62 I consider that these matters provide the necessary context in which the relevant paragraphs in the primary judge's reasons are to be read. In my opinion, no legal error is disclosed in those paragraphs. His Honour's rejection of the Appellant's submissions simply reflects how the Appellant chose to plead and present his case below.
63 For completeness, I should also add that, while I respectfully disagree that the primary judge reversed the onus of proof, if his Honour did do so I agree with Perram J that there was evidence below to support a finding that the ASB Respondents had adduced enough evidence to discharge their onus of proof, with the consequence that any such error on the part of the primary judge was immaterial.
64 For these reasons, I agree with the orders proposed by Perram J.
I certify that the preceding seventeen (17) numbered paragraphs are a true copy of the Reasons for Judgment herein of the Honourable Justice Griffiths.
