14 In order for the plaintiffs' cause of action to be complete, the plaintiffs' actual damage must be "measurable" ( Wardley at 531), or, in the words of Lord Reid in a personal injuries case ( Cartledge v E Jopling & Sons Ltd AC 758 at 772) the damage must be "beyond what can be regarded as negligible".
21 Reasons for requiring the occurrence of actual and measurable loss are given in Wardley by Mason CJ, Dawson J, Gaudron J and McHugh J at 527, as follows:
In many instances the disadvantageous character or effect of the agreement cannot be ascertained until some future date when its impact upon events as they unfold becomes known or apparent and, by then, the relevant limitation period may have expired. To compel a plaintiff to institute proceedings before the existence of his or her loss is ascertained or ascertainable would be unjust. Moreover, it would increase the possibility that the courts would be forced to estimate damages on the basis of likelihood or probability instead of assessing damages by reference to established events. In such a situation, there would be an ever-present risk of under-compensation or over-compensation, the risk of the former being the greater.
22 Wardley established that a person granting an indemnity, under which he or she is obliged to make a payment when the loss of the party to be indemnified is ascertained and quantified, suffers no actual loss until this contingency is fulfilled; so that a cause of action for purely economic loss, dependent upon damage being caused by the granting of the indemnity, does not arise until that contingency occurs. However, during the discussion of this question at 175 CLR 527-533, the majority of the High Court did not disapprove of Forster v. Outred & Co. [1982] 1 WLR 86, where it was held that a plaintiff suffered actual loss, not merely prospective loss, when, on negligent advice from her solicitors, she granted a mortgage over her property to secure debts of her son.
23 Their Honours in Wardley at 529 explained Forster by reference to the immediate effect of the plaintiff's execution of the mortgage, namely, an immediate reduction in the value of the plaintiff's "equity of redemption". I think it might be more accurate to say that the effect was a reduction in the value of the plaintiff's property: prior to the granting of the mortgage, the plaintiff owned the property unencumbered, so at that stage there was no "equity of redemption". By executing the mortgage, she made the property more difficult to sell, irrespective of whether or not her son ultimately defaulted on his debts: a purchaser would pay less for the property with a mortgage still on the title, and the plaintiff would have to come to some arrangement with the mortgagee in order to remove it from the title. As I understand it, that is the immediate loss that arose in Forster.
24 In Cassis v. Kalfus [2001] NSWCA 460 at [71]-[76], I adverted to the relevance of Sellars v. Adelaide Petroleum (1994) 179 CLR 332 to the question of when economic loss occurs. That case established that the loss of a chance having commercial value is actual damage that can complete a cause of action in tort. However, there is a significant difference between the loss of a chance, on the one hand, and the chance of a loss, on the other.
25 In the former case, where a chance is lost, it will never be known how things would have turned out if the chance had not been lost, so that the only possible compensation a plaintiff can obtain is compensation for the value of the chance itself. Accordingly it is reasonable to require a plaintiff to commence proceedings within the limitation period once the chance has been lost, and reasonable to award damages on that basis against a defendant.
26 On the other hand, where a person incurs a chance, even a substantial chance, of suffering a loss, in due course it may become clear that no loss is ultimately suffered; and so long as there is some appreciable chance that no loss will be suffered, it is unreasonable to require a plaintiff to commence proceedings and unreasonable to award damages against a defendant. However, once there is actual loss, even if there is also the chance of further loss, a plaintiff must commence proceedings within the appropriate limitation period, and can obtain damages reflecting actual loss suffered plus damages reflecting the chance of any further loss.
27 A defendant bears the onus of proof of establishing that actual and measurable loss first occurred before a date six years before the commencement of proceedings: Sorrenti v. Crown Corning Limited (1986) 7 NSWLR 77 at 80, Pullen v. Gutteridge [1993] 1 VR 27 at 71-6, Bailey v. Redebi Pty. Limited (1999) Aust.Torts.Rep. 81-523 at 66,286, Cigna Insurance Asia Pacific Limited v. Packer (2000) 23 WAR 159, Cassis v. Kalfus [2001] NSWCA 460 at [65].
28 In this case, as recognised by the primary judge, the failure to remove the 1976 right of way meant that the opponent's land was not as valuable as it would have been if the right of way had been removed: in that respect, the case is closely analogous to Forster v. Outred. In those circumstances, in my opinion, although the ultimate onus was on the claimant, there was an evidentiary onus on the opponent if the opponent wished to claim that this apparent immediate loss was either illusory or negligible: this may have been achieved if, for example, it could have been shown that there would have been negligible expense, delay and risk in having the right of way removed, or some countervailing benefit that could outweigh this loss. There was in this case no suggestion of any countervailing benefit. There was evidence that the opponent had a good case for rectification and specific performance, but there was no evidence that Mr. Toltz would have acceded to a demand for removal if made to him at that time, or that there would not have been court proceedings contested to some extent at least. In the absence of further evidence of that kind, it would be inferred that at least some expense, delay and risk would be involved in seeking rectification of a contract and specific performance of the contract as rectified, even assuming there was a good basis for bringing those proceedings. In my opinion, this means that the apparent immediate loss of value of the opponent's land could not be considered illusory or negligible. Damages would have been immediately recoverable, albeit substantially discounted because of the good chance of retrieving the situation.
29 For that reason, in my opinion, at least some actual and measurable damage occurred at about the time of the sale to Mr. Toltz (it does not matter whether it be at the time of completion or at the time of registration of the transfer), so that any cause of action based on the claimant's negligence prior to that time was statute-barred by June 2000. I have already noted that the preferable view of the Statement of Claim is that the negligence it alleges is negligence occurring at about the time of the sale to Mr. Toltz; so, on that interpretation of the Statement of Claim, the only cause of action pleaded is statute-barred. Unless the Statement of Claim is amended, this finding would put an end to the proceedings; and in those circumstances, it would be appropriate to grant leave to appeal and uphold the appeal.
30 Mr. Lynch submitted that, in so far as the claimant's negligence consisted in failure to draft a special condition 11 entitling the opponent to removal of any easement giving access to Double Bay, that resulted only in the difference between a claim in contract and a claim for rectification; and that this difference would not be an actual measurable loss.
31 I accept that such a difference would only amount to a chance of a loss; but the submission has two difficulties. One is that the Statement of Claim does not allege negligence in respect of the drafting of special condition 11: that could perhaps be overcome by an amendment, although there may be problems in severing alleged negligence in drafting special condition 11 and from negligence in failing to ensure that the right of way was removed on completion of the sale. The other difficulty is more serious, namely that this negligence, if it can be so severed, never caused any more than the chance of a loss: this negligence did not contribute at all to the ultimate loss of the chance of remedying the situation, which occurred in about September 1994.
32 Mr. Lynch also submitted that there was a possible cause of action in negligence based upon the events of August 1989, in respect of which no damage was suffered until the sale by Mr. Toltz in 1994: at that time, the claimant advised that there was no need to do anything to obtain removal of the 1976 right of way, with the result that the opponent lost the opportunity to bring proceedings for rectification and specific performance. I have noted Mr. Davies' submission that loss for any such negligence started occurring immediately after August 1989: the remedies of rectification and specific performance are discretionary, and any delay in bringing them reduces the chances of success. Accordingly, he submitted, loss occurred progressively from August 1989 onwards.
33 In my opinion, that submission is incorrect. Until the sale by Mr. Toltz in September 1994, the opponent still had the chance of obtaining relief through rectification and specific performance, even if that chance was somewhat reduced from what it had been in August 1989 because of the intervening delay. But the question is whether that delay involved actual and measurable loss, or alternatively involved loss which was no more than contingent or prospective. In my opinion, any such loss prior to September 1994 was plainly no more than contingent or prospective. If the opponent had sued the claimant prior to September 1994 without first taking and losing the rectification and specific performance proceedings, the claimant could have submitted that the opponent had not proved actual loss, because the Court could still grant the same relief as it would have granted if proceedings had been brought in 1989.
34 On that analysis, between August 1989 and September 1994, the opponent incurred no more than the chance of a loss, that is, the chance that the delay would have made a difference to the outcome of the rectification and specific performance proceedings, which were open to be taken by the opponent in 1994 just as they were in August 1989. Accordingly, in my opinion there was no complete cause of action based on any negligence occurring in August 1989 until the sale by Mr. Toltz in September 1994; and that cause of action was not statute-barred when these proceedings were commenced in June 2000.
35 In order to be able to rely on this cause of action, the opponent would need leave under Supreme Court Rules Pt.20 r.4(5), so that the commencement of the amended proceedings would relate back to the commencement of these proceedings. It is my opinion that such leave could be granted. This would I think be "a new cause of action arising out of the same or substantially the same facts" as in the current Statement of Claim: I noted earlier that the failure to cause the extinguishment of the 1976 right of way was generally pleaded, so this Statement of Claim would differ from the original Statement of Claim only in making it clear that the failure to secure removal of the right of way relied on was associated with negligence occurring in August 1989 rather than, as the present pleading tends to suggest, negligence occurring in about September 1986 or May 1987. In my opinion, the circumstance that the claimant has a good limitation defence to the whole of the present Statement of Claim does not preclude an order for amendment under Pt.20 r.4(5).
