Has the defendant adopted a position from which he cannot now resile?
31In my view, the inclusion of the statement in the defendant's written submissions that the "best evidence available of the true amount of the Skywalk Capital Expenditure is the estimate of the ... independent quantity surveyor Rider Hunt, that being ... $3,798,820", must be understood in its context. Prior to reaching this point in his written submissions, the defendant had advanced several arguments as to why the evidentiary material produced by the plaintiff did not substantiate its alleged quantum of Skywalk Capital Expenditure. It was only after advancing these reasons, most of which I accepted, that the defendant concluded his submission by further asserting that, in any event, the "best evidence" available, which was not good evidence, indicated that Skywalk Capital Expenditure was in the vicinity of $3,798,820, thereby casting significant doubt on the reliability of the evidentiary basis of the plaintiff's assertion of $7,009,407.
32Although counsel for the plaintiff argued that the defendant should not be permitted to resile from his previous "best evidence" submission, he did not base that argument on principles of admission or concession (see for example Nominal Defendant v Gabriel (2007) 71 NSWLR 150 at [103] and following, per Campbell JA), or on another well-established preclusionary doctrine, such as waiver, estoppel or election (see transcript around pages 5 and 6).
33When asked directly to articulate the legal basis of his submission that the defendant had adopted a position from which he could not resile, counsel for the plaintiff cited the English authority of Express Newspapers plc v News (UK) Ltd [1990] 1 WLR 1320, which he alleges was accepted by the High Court, to the effect that "there is a principle of law of general application that it is not possible to approbate and reprobate".
34I will briefly set out the facts of that case. The plaintiff published on 3 April 1989 in the "Daily Express" an article, based on an exclusive interview, which quoted the words of the person interviewed. The first defendant published a report of the same story in its newspaper, "Today", on the same day. In the second edition of "Today" the story appeared in an altered form, similar to that in the "Daily Express", and containing the same quotations, without acknowledgment of the source of the story or the quotations. The plaintiff brought an action for breach of copyright in respect of that report. On 9 October 1989 the first defendant published an article on an unrelated topic, also based on an exclusive interview. On 10 October 1989 the plaintiff published a similar story in one of its newspapers, the "Daily Star". On 16 October 1989 the defendants served a defence to the plaintiff's claim, and the first defendant served a counterclaim in respect of the October article which was in form, the mirror image of the plaintiff's claim. On 18 October 1989 the plaintiff obtained summary judgment on its claim, with an order for an inquiry into damages.
35The first defendant's claim for summary judgment on the counterclaim succeeded. It was held that although the plaintiff had an arguable defence to the counterclaim in that it might establish a press custom of adoption of news stories appearing in other newspapers, either with or without acknowledgment, its resistance to judgment on the counterclaim was wholly inconsistent with its own claim that on legally indistinguishable facts there was no arguable defence to a claim for breach of copyright. It was held that, under the doctrine of approbation and reprobation, which was of general application, the plaintiff was not entitled to put forward two inconsistent cases. Accordingly, despite the existence of an arguable defence to the counterclaim, the first defendant was entitled to judgment.
36In the subsequent case, Oliver Ashworth (Holdings) Ltd v Ballard (Kent) Ltd [2000] Ch 12, Robert Walker LJ left open whether, in cases such as these, there existed a "third route", besides estoppel and election. He did so after reference to a principle of Scottish law that recognises an equitable election, known as "approbate and reprobate". Ultimately, his Lordship put the question aside as he did not consider it necessary to decide the matter in that case.
37In K Handley, Estoppel by Conduct and Election, (2006) Sweet & Maxwell, the author suggests that the "approbate/reprobate" terminology refers to the known principle of election, originally used in Scots' law in connection with selecting between inconsistent rights in wills and contracts. He comments (at [14-004], some footnotes omitted):
Equitable election, or election between estates, is sometimes referred to as the doctrine that a person cannot approbate and reprobate [Footnote: This is the description of a similar doctrine in Scots law], although this description has also been applied to election between rights. Equity requires an election when a person received a gift under a will or other instrument which purports to dispose of some of his property in favour of another. If he elects to accept a gift he must give effect to the disposition of his property or compensate the other donee. Election between estates requires a deliberate choice by the elector with knowledge of his rights. It has been a potent source of confusion because decisions on this doctrine have been cited in cases of election between rights.
38In A K Turner, Spencer Bower and Turner: The Law Relating to Estoppel by Representation, 3rd ed (1977), the author comments (at [336]):
Taking a benefit: approbation and reprobation: blowing hot and cold
We have seen that an election is not final, and irrevocable by the elector, unless it has been communicated to the other party concerned, with the result moreover that that party has acted upon the faith of it so that it has become unjust that the elector should now be allowed to change his mind. But though not yet irrevocable, an election may yet be effective as between the parties, even though it has not been communicated by the elector to the other party, in a case where, though that other party has not been prejudiced, the elector has accepted a benefit which could be his only because he has followed one course rather than the other. In such a case he will not be allowed to reverse his choice and to follow the second course available, while he retains the benefit which could be his only if he followed the first course. The principle which brings about this result is sometimes stated as declaring that a man may not simultaneously approbate and reprobate, or may not "blow hot and cold".
In cases, however, where it remains possible for the elector to return the benefit which he has accepted, so as to remove the objection of his having approbated the first course, he will be allowed to do so, and when this has been done there will remain no difficulty in the way of his changing his mind and adopting the second course - so long as, in the meantime, notice of his having elected in favour of the first course has not been given to the other party interested, with the result that it has now become unjust, by reason of his having acted on the faith of the election, that such a change in attitude should be permitted.
This is well illustrated by Scarf v Jardine, usually regarded as one of the great election cases ... The explanation [of what was held in that case] lies in the doctrine of approbation and reprobation.
39In P W Young, C Croft and M L Smith, On Equity, (2009) Thomson Reuters, the authors comment (at [12.640]):
In Scots' law, the doctrine of equitable election is known as the doctrine of "approbate and reprobate", and this phrase describes something of its effect. The doctrine applies when a testator makes a gift in their will to A, but also purports to make a gift of A's property to B.
40In the classic work of John S Ewart, Waiver Distributed, (1917) Cambridge: Harvard University Press (at 67-69 and 112-113), the author's observations again indicate that the doctrine was first developed in the law relating to wills and succession, although he does appear to contemplate a broader application.
41It appears, from these quotes and from the discussions that follow them, that the "approbate/reprobate" doctrine probably originated in a context in connection with wills and estates, but was subsequently extended to operate in a contractual context, and has been applied to the conduct of litigation (for example Express Newspapers plc v News (UK) Ltd).
42The terminology "approbate and reprobate" has been referred to in passing by the High Court in a number of early cases (see for example, among numerous other cases, Grundt v Great Boulder Pty Gold Mines Ltd (1937) 59 CLR 641 at 657 per Latham CJ; R v Associated Northern Collieries (1911) 14 CLR 387 at 623 per Isaacs J; Stewart v Williams (1914) 18 CLR 381 at 408 per Isaacs J; Penny v Milligan (1907) 5 CLR 349 at 367 per Isaacs J, citing Codrington v Codrington (1865) LR 7 HL 854 at 861). In each of these cases however, it is clear that the doctrine preventing a party from departing from an assumption does not operate at large, but only operates to prevent an unjust departure from the assumption. For example, the assumption pressed by one party, from which it later seeks to depart, must have enabled it to obtain some advantage, and if the assumption is not adhered to, it would operate to another party's detriment. Whether or not a departure is unjust and inadmissible depends on the part taken by the party in occasioning its adoption by the other party (see for example Dixon J in Thompson v Palmer (1933) 49 CLR 507 at 547, whose comments on estoppel in pais were adopted by Latham CJ in Grundt v Great Boulder Pty Gold Mines Ltd as the basis for the operation of the "approbate/reprobate" doctrine).
43More recently, in Agricultural and Rural Finance Pty Ltd v Gardiner (2008) 238 CLR 570, a majority of the High Court (Gummow, Hayne and Keifel JJ, Heydon J relevantly agreeing) indicated that the "approbate and reprobate" doctrine was "but a synonym for the equitable doctrine of election" (at [57]). Their Honours also warned of the danger of seeking to apply the doctrine in "radically different" contexts. Their Honours also indicated that the principle was not one which operated at large, but, in line with the comments made in the early High Court authorities and the texts cited above, requires something more. Their Honours said (at [57], citations omitted):
[57] It should be noted that the equitable doctrine of election has a distinct character and application, and, as explained by Viscount Maugham in Lissenden v CAV Bosch Ltd has no connection with the common law principle putting a party to an election between alternative rights or remedies. Equity fastens upon the conscience of a party taking under a deed or will and requires the party to choose between taking the benefit and accepting the burden of any stipulated conditions or rejecting the benefit. Viscount Maugham explained in this connection that the phrase "you may not both approbate and reprobate", which was derived from the civil law and "from the northern side of the Tweed", when used in English law was but a synonym for the equitable doctrine of election.
44Their Honours then considered the traditional doctrines of election, forbearance, abandonment, renunciation and waiver, and finally noted (at [98]-[100]):
A residual category or general principle?
[98] As explained earlier in these reasons, the submissions in this litigation have not been based upon the existence of some residual category or general principle of "unfairness" at common law which is distinct from the case of "waiver" upon which reliance was placed, and from the principles of "election", "forbearance" and "renunciation". That makes it unnecessary to determine whether such a residual category or general principle exists in the common law of Australia. However, this silence on the subject should not be taken as an encouragement to further speculation.
[99] It may be thought that some degree of support for such a category or principle of unfairness is to be found in some decisions in other jurisdictions. However, two observations may be made respecting what has been said in certain decisions in the United Kingdom, Canada, New Zealand and the United States.
[100] First, "waiver" is sometimes used, as it is in Australia, in contexts that are far removed from the contractual context presented in this case. Decisions made in those other contexts, such as decisions about the "waiver" of constitutional rights do not bear upon issues of the kind now under consideration. Secondly, decisions in other jurisdictions lend weight to the observation of Lord Wilberforce, in Mardorf Peach & Co Ltd v Attica Sea Carriers Corporation of Liberia , that "the word 'waiver', like 'estoppel', covers a variety of situations different in their legal nature, and tends to be indiscriminately used by the courts as a means of relieving parties from bargains or the consequences of bargains which are thought to be harsh or deserving of relief". The need for coherence of legal principle and the effects of overly broad interpretations of waiver and estoppel upon other doctrines must be borne in mind. Further, in some cases the reference to "unfairness" may not be to a defining principle. For example, when analysed in the case of an estoppel, it may convey no more than that there has been no detrimental reliance to found the estoppel.
45In my view, the defendant's conduct does not prevent him from taking the position which he now seeks to take. That is because, as I have said, the defendant's submission (properly understood in context) did not amount to an admission, nor a concession, nor an acceptance, nor an acknowledgement, nor even the promotion of an assumption, that Skywalk Capital Expenditure should be taken to be $3,798,820, nor did the defendant invite the court to make any finding about the quantum of Skywalk Capital Expenditure (other than that it was not proven to be above $5 million), nor was it in his forensic interests to do so. The position taken by the defendant was to put the plaintiff to proof on every dollar allegedly incurred by way of Skywalk Capital Expenditure, not just any amount above $5 million.
46In my view, the defendant's "best evidence" submission was no more than one of a number of arguments to support his submission that the evidence on which the plaintiff's figure for Skywalk Capital Expenditure was based is flawed. That argument was made in closing submissions, and could therefore not have altered the manner in which the plaintiff would have conducted its case. Furthermore, it is apparent from the principal judgment that, although I noted the defendant's submission that the figure in the Rider Hunt estimate was the "best evidence" of true expenditure (at [168]-[170]), my rejection of the plaintiff's claim for Skywalk Capital Expenditure (i.e. the "advantage" obtained by defendant), was clearly not based on any acceptance of the defendant's "best evidence" submission, but simply on the basis of the multiple deficiencies in the plaintiff's evidence (at [105]-[167]). The defendant has not gained any advantage form his "best evidence" submission. Furthermore, the plaintiff did not even purport to adopt or rely on the defendant's "best evidence" submission, but indeed criticised it in reply submissions, and did not seek to rely on it as a fallback position (plaintiff's written submissions dated 13 December 2012 from [65]). I therefore do not consider the "approbate/reprobate" doctrine to be of any assistance to the plaintiff.
47I also note that, in support of its argument, the plaintiff indicated that the defendant had briefed its forensic accounting expert, Mr Blythe, with an instruction to assume for the purpose of his calculations, that Skywalk Capital Expenditure was the figure of $3,798,820 contained in the Ryder Hunt report. The plaintiff says this supports its assertion that the defendant adopted a position from which he cannot now resile. I reject that submission. Mr Blythe did not verify the accuracy of the assumption he was asked to make, nor could I possibly draw the inference that a mere request by a party to its expert to make a particular assumption, as part of a set of alternative assumptions, when preparing his or her expert report, amounts to an acceptance, concession or acknowledgement of the accuracy of the assumption.
