21 His Honour followed up this latter point at 532, saying that, in relation to matters of fact, "the issue-estoppel is confined to those ultimate facts which form the ingredients in the cause of action, that is, the title to the right established". Those facts were, his Honour said later on the same page, facts "fundamental to the decision arrived at". Those facts, together with their "legal quality", "must be taken as finally and conclusively established." His Honour contrasted "matters of law or fact which are subsidiary or collateral". Those matters, his Honour said, "are not covered by the estoppel". Further, findings "which concern only evidentiary facts and not ultimate facts forming the very title to rights give rise to no preclusion."
22 As his Honour noted at 533, the difficulty was not so much the statement of the principles as their application. The problem "is to distinguish the matters fundamental or cardinal to the prior decision or judgment, decree or order or necessarily involved in it as its legal justification or foundation from matters which even though actually raised and decided as being in the circumstances of the case the determining considerations, yet are not in point of law the essential foundation or groundwork of the judgment, decree or order."
23 His Honour's analysis was dealt with at some length in Chapter 8 of Spencer Bower and Handley, Res Judicata (Fourth Edition, 2009) at 103 and following.
24 In the present case, it seems to me to be strongly arguable that when one has regard to the grounds stated in the application with which Lloyd J dealt, and to his Honour's characterisation of the issues, the fundamental question was whether the council considered, in the sense explained by his Honour (or, as the grounds had it, considered according to law, or considered in a proper, genuine and realistic way, or on the basis of sufficient evidence) the relevant matters. The conclusion to which Lloyd J came was, as I have said, that the council did take into consideration the relevant matters, and that if its conclusions following that consideration were factually incorrect, that was not a ground of invalidity.
25 In those circumstances, it seems to me that there is much to be said for the view that the ultimate fact, or matter fundamental or cardinal, decided by the Court was the question of whether the council considered, in the requisite sense, relevant matters. The findings of fact along the way to that, although no doubt the determining considerations leading to the ultimate conclusion, may not be the essential foundation or groundwork of the Court's judgment.
26 In those circumstances, I think the better view may very well be that there is no issue estoppel. However, for the reasons that I indicated earlier, I do not regard this as an appropriate forum in which to consider the issue, because it will be relevant to understand not only the precise ambit of the facts that are the subject of estoppels flowing from the decision of the Lloyd J but also the facts sought to be proved, for the purposes of the compensation issue, through the report of Mr Taylor. It is sufficient to say that, having come to the conclusions that I have expressed, I am not prepared to vacate orders 2 and 5. I should make it plain that I have expressed myself in this way so that the parties are not bound, perhaps inadvertently or in a way that they had not contemplated, by my prima facie expression of opinion as to the existence of any relevant issue estoppel.
27 It follows from that that Tanlane's notice of motion should be dismissed in so far as it seeks a vacation of orders 2 and 5. However, it needs further consideration insofar as it seeks further directions in relation to the preparation of the compensation issue, and I will return to that.
28 I turn now to Moorebank's notice of motion. It seems that the evidence of the surveyor, a Mr Asher, is intended to establish that there has been no substantial commencement, under the development consent granted by council, for the purposes of s 95 of the Environmental Planning and Assessment Act. Mr Inatey SC who appeared with Mr Wilson of counsel for Moorebank, submitted that the question of the existence of the development consent was relevant to the valuation of his client's land, and therefore to the impact of the easement if granted. However, it appears, the valuation reports that his client have served assume that the consent is valid. If this is so then I have a little difficulty in understanding how the question could have the relevance for which Mr Inatey contended.
29 In any event, it seems to me, the assessment of compensation is to be assessed on the basis that there is, or will be, a valid consent. That seems to me to follow in effect from what Young CJ in Eq said at [116] of his reasons.
30 Further, on this issue, if there is to be a real question as to the basis upon which the valuation should be undertaken, then it would be entirely in accordance with usual practice for the valuers to prepare their opinions on alternative bases, and for the Court to make findings on those alternative bases, so that when (if at all) the matter returns to Young CJ in Eq, and his Honour considers the question reserved by [116] of his reasons, he can select the appropriate option.
31 Mr Hale raised other matters in opposition to the notice of motion. Given that I have concluded, for the reasons that I have expressed, that the notice of motion fails, it is not necessary to deal with those.
32 It follows that directions should be given on Tanlane's notice of motion, but that otherwise it should be dismissed; and that Moorebank's notice of motion should be dismissed. Since the substantive issues argued on each of the motions have failed, I would have thought either that there should be no order as to costs or that there should be orders for costs following the substantive event in each case, and that costs be set off. I will hear the parties on that, and on the question of directions.
(Counsel addressed.)
33 On the plaintiff's notice of motion, I reserve the question of directions and reserve liberty to apply in chambers, but order that the notice of motion otherwise be dismissed. I order that the defendant's notice of motion be dismissed. I make no order as to the costs of either notice of motion.
34 I order that the exhibits on the notices of motion be handed out.
