What is the 'Ultimate Issue Rule'?
33 What is the 'ultimate issue rule?' To this question, no easy answer offers itself. One helpful explanation was provided by Neville J in Joseph Crosfield & Sons Ltd v Techno Chemical Laboratories 29 TLR 378 at 379: 'It is not competent in any action for witnesses to express their opinion upon any of the issues whether of law or fact which the Court or a jury has to determine.' This was quoted with approval by Mr G.J. Samuels (as he then was) in a paper later published in HH Glass QC (ed) Seminars in Evidence (1970) at p151. The commentator, later Samuels JA of the New South Wales Court of Appeal, (at p152) gave three reasons for the justification of the rule: first, so as far as possible to prevent a plethora of competing opinions. Second, to prevent expert opinion from overbearing the jury's duty to make up its own mind. Third, to exclude advocacy in the guise of expert opinion. Later the learned author formulated the rule as follows (at 153): '[a]n expert cannot be permitted to give expert opinion upon an ultimate issue, if its determination depends on the application of some legal standard.'
34 In Transport Publishing Co Pty Ltd v The Literature Board of Review (1956) 99 CLR 111 at 127 Webb J adverts briefly to the principle as does Dixon CJ in Clark v Ryan (1960) 103 CLR 486 at 491. It received helpful exposition in R v Palmer [1981] 1 NSWLR 209 where Glass JA said (at 214):
'The third ground argued was that the tender of such evidence violated a supposed rule that no opinion evidence, whether expert or non-expert may be directed to an ultimate issue for determination by the jury. I question that there is any such rule in the terms which have been submitted to us. It is a commonplace experience in trials, both civil and criminal, before juries for evidence of opinion to be received from both experts and non-experts in relation to ultimate issues for jury determination. I need only say, so far as expert evidence is concerned, that this happens all the time with respect to scientific, medical and handwriting evidence and so far as concerns non-expert opinion, that this, too, is receivable for the purpose of identification of proof of speed. The true rule, in my opinion, is that no evidence can be received upon any question, the answer to which involves the application of a legal standard . It is not possible, for example, to tender evidence that a defendant was negligent, that a deceased lacked testamentary capacity or that the accused was provoked. These are questions, the answers to which can only be given by the jury after the judge has instructed them upon a rule of law which they must apply.' [emphasis added]
35 Earlier in Grey v Australian Motorists General Insurance Co Pty Ltd [1976] 1 NSWLR 669 at 675 - 676 Glass JA had offered another formulation, different in terms but no different in substance. But even understood in the limited fashion outlined by Glass JA, the cases disclose no consistent application. In R v Holmes [1953] 2 All ER 324 the English Court of Criminal Appeal allowed an expert witness to express a view as to whether a defendant knew the nature of his act and that it was wrong where the defendant pleaded insanity. In Lowery v R [1974] AC 85 it was held by the Privy Council that an expert could give an opinion as to which of two defendants was more likely to have committed a particular offence. No doubt, it was the inconsistency of the application of the ultimate issue rule which lead Mason CJ and Toohey J in Murphy v The Queen (1989) 167 CLR 94 at 110 to state that '[i]t is doubtful that there is now an absolute rule precluding an expert witness from expressing a view as to the ultimate issue.' The matter was considered by Priestley JA (with whom Kirby P and Samuels JA agreed) in ULV Pty Ltd v Scott (1990) 19 NSWLR 190 where his Honour commented (at 202) that '[a]ll the persons who have written on the subject since 1960 have commented on the difficulty of stating any clear rule.' His Honour then quoted (at 203) with approval from the Australian Law Reform Commission Research Paper No 13 entitled 'Opinion Evidence' where the Commission had commented as follows:
'One of the few common things that can be asserted with confidence in relation to the ultimate legal issue rule is, therefore, that a witness be he expert or common, may not offer his opinion on any matter which involves his use of a 'legal' term. So too, though, may it be said that there is a substantial move away from the concept that evidence should never be given on any ultimate issue. In recognising the reality of the situation, however, the courts have continued to have problems in grappling with the theoretical problems that they have created for themselves in formulating the ultimate issue rule. This causes the situation to remain uncertain.'
36 Notwithstanding the uncertain nature of the rule, its core component concerns evidence of an expert as to the satisfaction or not of a standard which has legal effect. Thus, the rule would encompass evidence that a certain person had been, in the opinion of the witness, 'negligent.'
37 The next question is whether this rule was affected by the enactment of s80 of the Evidence Act.
38 In the first place, it may be said that I accept the defendants submission that the reports of the ALRC may be used as an aid to construction of s80 of the Evidence Act under s34 of the Interpretation Act 1987 because those reports are capable of assisting the ascertainment of the meaning of the provision either to confirm that the meaning of the provision is the ordinary meaning conveyed by the Act (paragraph 34(1)(a)) or because s80 is ambiguous or obscure (sub-paragraph 34(1)(b)(i), see especially subs-paragraph 34(2)(b) and (f)). Alternatively, they may be used under the principle explained by McHugh J in Newcastle City Council v GIO Insurance Ltd (supra, at 112) as follows:
'... a court is permitted to have regard to the words used by the legislature in their legal and historical context and, in appropriate cases, to give them a meaning that will give effect to any purpose of the legislation that can be deduced from that context. The context includes reference to the provision's legislative history and the relevant reports of law reform bodies which detail the perceived evil requiring reform.'
39 When they are examined, those extrinsic materials reveal, to my mind, a clear intention to abolish the rule which prevented a properly qualified expert expressing an opinion as to the satisfaction or otherwise of a certain legal standard. Furthermore, this is what s80 achieved by using words of clarity and economy. The effect of s80 is not to permit evidence which goes to an ultimate issue at all events; neither is it a section which works to exclude evidence. Its effect is to remove the fact that the evidence goes to an ultimate issue from the reasons for which a court must or could exclude the evidence. That is the clear effect of both the words of s80 and the intention of the legislature and the ALRC as disclosed in the extrinsic materials to which I have referred.
40 I reject the plaintiffs' contention that in some way the ALRC Report was obscure or confused as to what the ultimate issue rule was. On the contrary, although the Report identifies the difficulty of the so-called rule, to my mind, it clearly identified the subject of its discussion when it said (at p412 of the Interim Report) that '[i]t has been suggested that the true analysis of the rule is that it prohibits a witness applying any kind of a 'legal standard' to the facts' and was clear beyond peradventure when it proposed that 'the ultimate issue rule be abolished' (at p413). The Second Reading Speech of the Attorney General, and in particular that extract I have quoted above, makes clear that the ALRC's proposition was accepted and found expression in s80.
41 Furthermore, there is authority for this proposition. In Walton v Corporate Venture Pty Ltd (unreported, ACT Supreme Court, 6 June 1996) Miles CJ commented (at p11) that '[t]he old rule that an expert may not express an opinion on the ultimate issue that a court has to decide, died long ago and was buried by s80 of the Evidence Act 1995. But there is, for practical purposes, an immense difference between a doctor advising lawyers as to his opinion on the ultimate issue and the lawyer tendering that advice in proof of that issue.' His Honour's final comment can only be understood by reference to the preceding paragraph of the judgment where it emerged that the subject opinion was contained in a letter written by the expert to the plaintiff's solicitor and divorced from any reasoning or relevant field of expertise. His Honour's final remark should not be understood to detract from the balance of the quotation.
42 In Daniels v State of Western Australia [2000] FCA 858 (unreported, Federal Court of Australia, 21 of September) R.D. Nicholson J considered evidence of an expert anthropologist in the context of a claim under the Native Title Act 1993 (Cth) that 'in my opinion, the Burrup is Ngarluma land and all members of the Ngarluma language group have interests in it under Aboriginal law.' R.D. Nicholson J (at para 18) said:
'Section 79 is followed by s80 in which it is provided that evidence of an opinion is not inadmissible only because it is about a fact in issue or an ultimate issue or a matter of common knowledge. That is also a change to the common law position. The opinion would not therefore be precluded from admission by the fact that it related to the ultimate issue of native title in relation to the Burrup.'
(iii) Effect of s80 on the Principles Regarding Admission of Evidence of Foreign Law
43 In this case, I do not find it necessary to decide whether Lindgren J was correct when he decided in Allstate that the words of s80 'are not apt to refer to expert legal opinion which impinges upon the essential curial function of applying the law, whether domestic or foreign to the facts.' This is because, even if the evidence of the application of foreign law is accepted in this case, it will not 'impinge on the essential curial function.' The decision of Lindgren J in Allstate must be viewed within the context of the function to be performed by the application of foreign law in that case. The facts of that case (which can be found at (1996) 64 FCR 1 at 1 - 24) concerned, relevantly, the issue of a prospectus in the United States which, it was claimed, inter alia, breached s12(2) of the Securities Act 1933 (US). It was to that issue that the evidence of Mr Altman was directed. Mr Altman gave evidence that under that statute one of the parties would be 'liable,' this being one of the very issues the court had placed before it by the parties for determination. In other words, in that case, the Court was concerned with the direct application of foreign law to facts so as to determine the rights and liabilities of the parties under it and the evidence of Mr Altman sought to provide an opinion which, if accepted, would dispose of that very issue.
44 This case falls into a different category. Here, the Court is not concerned to administer foreign law for the purpose of determining the rights and obligations of the parties under foreign law. The facts in issue all occurred within the jurisdiction of this Court. No issues concerning the exercise of foreign jurisdiction over the facts of this case arise. Here the court is concerned with foreign law as a subsidiary fact necessary to determine the rights and liabilities of the parties under the law of New South Wales. The essential curial function of this Court in this case is the administration of and the proper application of the law of New South Wales. Evidence of foreign law experts as to the effect of foreign law, where the effect of foreign law is relevant to the administration of domestic law, is not capable of usurping the function of the court any more than is evidence of any other fact relevant to the determination of the rights and liabilities of the parties under domestic law.
45 Where in this case an expert on foreign law expresses an opinion of the effect of foreign law on the facts of this case he or she does nothing different from a properly qualified expert who expresses an opinion to the effect that a particular person was 'negligent.' To say that a person was negligent does not usurp the essential curial function of the court, for evidence that a person was negligent does not determine the issue of whether that person is liable to pay compensation to another. Even if the court accepts the evidence, there are further issues for determination before the courts essential function is complete: the negligence must have caused damage, the damage must not be too remote and under the common law, there must have been an absence of contributory negligence. Like evidence of foreign law in a case such as the present, an opinion that a person was negligent is one fact in the factual matrix necessary to establish the rights and liabilities of the parties. Evidence of a properly qualified expert that a person was 'negligent' is a paradigmatic example of the sort of evidence that s80 was concerned to make admissible, where prior to the Act it was inadmissible, provided the evidence is otherwise admissible under the Evidence Act.
46 When the Court receives evidence of foreign law, including evidence of its content and likely effect, the approach to be taken is, to my mind, similar to that identified by Street J (as he then was) in Ancher, Mortlock, Murray & Wooley Pty Ltd v Hooker Homes Pty Ltd [1971] 2 NSWLR 278 where his Honour was concerned with conflicting expert evidence as to the existence of similarities or dissimilarities in certain architectural plans. Street J said at 286:
'In view of the volume of expert evidence, and the differing views expressed by the expert witnesses, I should state the use that can be properly be made of that evidence in reaching a decision in a suit such as this. The decision upon the issue of similarity is an original decision for the court itself. It is to be reached upon an assessment of such similarities and dissimilarities as appear to the court between the plans or buildings under consideration. The fact that one particular expert of the highest authority and of unimpeachable credit is permitted to swear to an opinion on similarity or dissimilarity does not relieve the court of responsibility of forming its own opinion on this issue. In this sense the expert evidence in a suit such as the present fills a somewhat unusual role. It is almost as if each side calls an expert to argue out with counsel in examination-in-chief and cross-examination the similarity or dissimilarity which that particular expert sees between plans or houses. By attending to the progress of this argumentative process between counsel and expert the court is enabled to perceive more readily appreciate the points of similarity and dissimilarity. In this way the tendering of expert evidence is of value in exposing the facets of the ultimate question to which the expert evidence is directed. But the important point is that, in distinction from the judicial process in relation to expert evidence such as is normally encountered in litigation, a court in the present type of litigation is entitled to and, indeed, bound, to form and act on its own original opinion. '
[emphasis added]
47 Likewise, in a case such as the present, it is necessary for the court to form its own view as to the effect of foreign law on the claims made by the plaintiffs, just as it is necessary for the court to form its own view on all the facts in issue necessary to determine the case. Expert evidence on such a question is necessary to inform the court of a matter in respect of which it is, ex hypothesi, ignorant. If the plaintiffs lead expert evidence in reply which is contradictory of the defendants expert's opinions, the contrast of reasoning and conclusion will allow the court to better perceive the foreign law issue and its likely solution. Cross-examination of the expert witnesses and the testing of the views and conclusions of the experts may further aid the Court's understanding. But no matter how eminent the various experts whose evidence is led by the parties and no matter how cogent or convincing their reasoning is and no matter how plausible their conclusion, the court must form and act upon its own view as to the effect of foreign law. This is also the approach of the High Court in Rogers v Whitaker (1992) 175 CLR 479 at 487 per Mason CJ, Brennan, Dawson, Toohey, McHugh JJ at 493 per Gaudron J.
48 The plaintiffs did not claim that the evidence was not relevant within the meaning of s55 of the Evidence Act. Neither did they contend that it was not properly within the exception to the opinion rule in 79. The only ground of exclusion claimed was that identified by Lindgren J in Allstate. For the reasons I have given, I reject this contention. Accordingly, I accept the defendants contention that in this case expert opinion evidence on the matter of foreign law may include the following matters:
(a) the existence, nature and scope of the rules and principles of law in a foreign jurisdiction.
(b) the meaning and effect to be given to both foreign statutory and common law.
