[72] Where, as here, the applicant on a stay motion seeks to rely upon a foreign lex causae as providing an advantage, then, at a level of specificity, the applicant should advance appropriate evidence as to the foreign law and particular features of that law which provide that advantage to the applicant."
19 Mr Joseph urges that the apparently general statement at the end of paragraph 71 must be read down by the question which the majority had posed for itself at the commencement of that paragraph. In other words, the requirement that a party who relies on a foreign law "must allege, and, if necessary, prove it" applies only to a plaintiff who seeks a forensic advantage from that law, such as in its provision for strict liability. Neither plaintiff in the present case is seeking such an advantage. It follows, Mr Joseph urges, that the plaintiffs do not need to plead Papua New Guinean law in their initiating process, and it is therefore unnecessary to amend their statements of claim so as to invoke that law. They are seeking to do so only for abundant caution. It would be open to the plaintiffs, according to this submission, to continue with their claims as currently framed and then rely upon Zhang at the hearing as providing that the applicable law is that of Papua New Guinea.
20 Mr Joseph's submission highlights an apparent ambiguity in the ambit of the requirement formulated by the majority in the last sentence of paragraph 71 quoted above. A recourse to the passage from Dicey cited by the majority does little to resolve the matter. Dicey's statement was made in the course of discussing the double actionability rule as it applies to defamation cases. It has little to do with choice of law rules.
21 I agree with Mr Joseph's submission as to the limited application of the requirement, specified by the majority in Zhang, that a party who relies on a foreign law must allege and, if necessary, prove it. Neither Pfeiffer nor Zhang sought to displace the presumption, referred to by Hutley J in Walker, that foreign law is presumed to be the same as local law. One must therefore ask why foreign law would need to be specially pleaded, unless a plaintiff was seeking to rely on some aspect of it which differed from local law or, to put it in the terms used in Zhang, was seeking to gain a "forensic advantage" under the foreign law.
22 The significance of this will depend, to some extent, upon an analysis of the effect of the choice of law rule expounded in Zhang, a matter I will be discussing shortly. In the meantime it is apposite to refer to a separate but not entirely unrelated submission made by Ms Katzmann.
23 Ms Katzmann pointed out that the defendant has not pleaded any defence under the Papua New Guinea limitations legislation. In the absence of any such defence the defendant could not, she submitted, raise an argument that the plaintiffs' claims were statute barred as a ground for opposing the amendments sought by them. The defendant's response to this submission was that, until the amendments sought by the plaintiffs are made, no foundation has been laid for pleading any such defence. There is an obvious circularity in these submissions. Effectively, I take the defendant to be saying that there would be no point in the Court allowing the amendments sought by the plaintiffs because the claims, as amended, would inevitably be met by a successful defence under the Papua New Guinea limitations legislation. Seen thus, the matter raised by the defendant might be categorised as raising a discretionary consideration. However it is one of such potential power that, if correct, it would outweigh all other considerations. There would be no point whatsoever in allowing the amendments sought by the plaintiffs if they were to be met, as the defendant asserts they would, with successful defences under the Papua New Guinea limitations legislation.
24 All of these submissions raise a fundamental issue as to the effect of the judgment in Zhang upon these proceedings. There is one obvious effect, namely that at the hearing of these actions the law of the place of the wrong, which in this case is Papua New Guinean law, will need to be applied in order to determine the substantive issues between the parties. There is much to be said, in my view, for the proposition that the impact of Zhang extends little if any beyond this. In particular, I am strongly inclined to the view that Zhang does not require that the law of the place of the wrong be pleaded by a party unless some facet of that law is to be relied upon which has no parallel in the local law. In the present case, the Papua New Guinea Wrongs Act is essentially identical with the NSW Act. That Act will be applied in these proceedings not because of the manner in which in the statements of claim have been framed, but by virtue of the applicable choice of law rules.
25 Both statements of claim in the present case were lodged within the limitation periods specified under both New South Wales and Papua New Guinean laws. Let us assume, for the moment, that the Papua New Guinean limitation laws provided more stringent time limits than those in New South Wales, with the result that the plaintiffs' claims were statute barred in Papua New Guinea but not in New South Wales. Until Zhang, this would have been an irrelevant matter as the applicable law in all respects was taken to be that of New South Wales. Since Zhang, it would be open for the defendant to amend its pleadings so as to add a defence that the plaintiffs' claims were statute barred under the New Guinea law, if that were the case. The defendant in that event would be seeking a "forensic advantage" under the foreign law which is not available under local law, and would need to specially plead it. However in the present proceedings this course is not open to the defendant, for both actions were commenced within the time limits allowed under both New South Wales and Papua New Guinea limitation laws.
26 A further illustration is provided by the circumstances of Mrs Dyer's action. When Mrs Dyer first applied to amend her statement of claim she sought to add an averment that she had been appointed administrator of her late husband's estate, and to insert a claim on his behalf for damages for loss of expectation of life. This is a cause of action in Papua New Guinea but not in New South Wales. In order to assert this claim, Mrs Dyer would need to amend her statement of claim so as to plead the appropriate Papua New Guinea law for she would be claiming a benefit under that law which is not available under local law. This would be a new cause of action, propounded by Mrs Dyer in her representative capacity, whereas the existing proceedings were propounded in her personal capacity. This being so, a defence under the Papua New Guinea limitations legislation would inevitably be successful. It was no doubt in recognition of this fact that Ms Katzmann withdrew the application to amend the statement of claim in this manner.
27 I return to my discussion of the effect of Zhang on the present cases. The mere fact that all parties believed, when these actions were commenced, that New South Wales substantive law would apply to the proceedings, is irrelevant for present purposes. That belief was later shown by the majority judgment in Zhang to represent an erroneous (or outmoded) view of the common law. Similarly, the fact that the statements of claim contained a reference to the New South Wales legislation was irrelevant. It was irrelevant on two bases: first because it was an unnecessary averment, and secondly because it did no more than state the parties' erroneous view as to the choice of law rules which would apply. It certainly did not amount to an "election" by the plaintiffs to invoke New South Wales law. Nor could it have been effective to do so, once Zhang had established that foreign law was to be applied in cases of this nature. As I have said, the Papua New Guinea law will be applied in these proceedings by virtue of the applicable choice of law rules, not because of any election by the plaintiffs or any averment in their statements of claim.
28 The defendant's arguments proceed upon the assumption that the effect of the plaintiffs' amendments will be to "harness" Papua New Guinean law for the first time. This pre-supposes that, without the amendments, or at least until they are made, the NSW Act will remain the governing legislation. But this cannot be reconciled with Zhang, which states that the law of the place of the wrong is to be applied in all cases involving foreign torts.
29 In my view it is unnecessary for the plaintiffs to amend their statements of claim in order to assert a claim under the Papua New Guinea Wrongs Act. Therefore there is no question of a defence being filed under the Papua New Guinea limitations legislation. Accordingly, the hearing of the matter has been able to proceed with the existing pleadings. The references in the statements of claim to the NSW Act are otiose and of no effect. Papua New Guinea law will be applied to all matters of substance between the parties.
30 This conclusion accords, in my view, not only with the legal analysis of the situation but also with justice and fairness. It would be unjust in the extreme if plaintiffs who had commenced proceedings within time could later find that their actions were statute barred simply because the prevailing choice of law rules had changed in the meantime. That is all that has happened here.
31 No amendment of either statement of claim is necessary. The actions are to proceed on the basis that Papua New Guinea law applies by dint of the choice of law rules. The costs of these applications are to be costs in the cause.
