The appeal, the cross-appeal, and their resolution
27By its appeal, Sydney Water contended that the primary judge erred in discounting the residential component only by 20%, by reference to the footprint of the easement, rather than by some 70%, by reference to the size of Lot 306. By its cross-appeal, Council contended that the primary judge erred in the further discounts of 25% allowed by the primary judge to the residential rate, and separately erred by regarding the SACL land as a comparable.
28That there is no question of law in either the appeal or the cross-appeal is readily apparent. An error of valuation principle may - but need not be - an error of law: Maurici v Chief Commissioner of State Revenue [2003] HCA 8; 212 CLR 111 at [8]. However, the fact that there was agreement on the applicable methodology to the extent reproduced at [8] above is a powerful indication that no error of law was involved in the present case. Morling J said as much in Nock v Minister for Capital Territory (1982) 48 LGRA 293 at 296:
"If it be accepted that no error of law was made by Mr Gowing in adopting his method of valuation, it is difficult to see how it can be argued that the tribunal erred in law in giving weight to a valuation made in accordance with it."
29It is convenient first to deal with the cross-appeal, where the position is clearest.
30Whether or not a sale is comparable is a matter of degree and judgment. It may be accepted that there can be error of law if the finding that a sale is or is not comparable was not reasonably possible or open on the evidence, or in making an adjustment which is not reasonably possible or open on the evidence. A line of consistent authority, collected in this Court's reasons in ISPT Pty Ltd v Valuer General [2009] NSWCA 31; 165 LGERA 25 at [23]-[25] supports those propositions.
31The position in respect of adjustments to comparable sales is the same. Almost every "comparable" sale requires adjustment. Hope JA said in Leichhardt Municipal Council v Seatainer Terminals Ltd (1981) 48 LGRA 409 at 434:
"The need to make adjustments to values deduced from sales in order to arrive at the true valuation of the land to be valued does not preclude the court which has the task of valuing the land from relying upon the sales as comparable in the relevant sense, nor from the making by the court or by valuers of adjustments which may be nothing more than the best guess that can be made."
32It is plain that whether or not an adjustment to a comparable sale should be made, and if so by what amount, is likewise a matter of degree and judgment.
33Both in identifying what is comparable, and in making appropriate adjustments, the position was described by Wells J in Brewarrana Pty Ltd v Commissioner of Highways (1973) 32 LGRA 170 at 180:
"... there is no hard and fast rule by the application of which a valuer may, whatever the circumstances, draw the line that clearly separates the sales that are comparable from those that are not. It is in my view, all a matter of degree: ... Just where the line is to be drawn is, it seems to me, the very sort of question that is fit for the expert valuer to determine; the assessment of the risks of adjustment is peculiarly within his sphere of skill."
34One valuer considered the sale of an easement over the SACL land to provide some evidence of value, another did not. The judge determined that it did, but only after making significant adjustments to it, and then as a minor (40%) contributor. No doubt the amount of the adjustments, and the 40% weighting, are contestable. But irrespective of that, and irrespective of whether there is any factual error in the approach, there is no error of law in the approach taken.
35It is no answer to this reasoning for the Council to point to the (large) magnitude of the adjustments. The "limits" to which Hutley JA referred in Housing Commission of NSW v Tatmar Pastoral Co Pty Ltd [1983] 3 NSWLR 378 at 383, and on which Council relied, are those stated at the conclusion of his Honour's judgment: limits of irrationality and failing to give effect to a principle of valuation. The fact that the primary judge considered that a large adjustment was required in order to allow for the differences between the Council's land and the SACL land does not mean that error of law is disclosed. His Honour's reasons for doing so were (no differently from every aspect of the exercise) contestable, but they were rational.
36Similarly, the primary judge discounted the value of the (formerly) residential land by reference to adjustments attributable, in his view, to the differences between land adjoining the western boundary of Lot 306, and the land alongside the canal which was subject to the easements. Again, the nature and extent of those adjustments were contestable, but there is no error of law in the approach taken.
37Sydney Water accepted that no error of law was disclosed by the inclusion of the (formerly) residential land as comparable sales, but submitted that error of law was shown by the adjustment of only 20% on the values achieved, calculated by reference to the area of land affected by the easement, as opposed to some 70%, by reference to the whole of Lot 306. Consistently with the more extenuated position taken by Council on its cross-appeal, Council did not submit that Sydney Water's ground did not raise a question of law. However, that does not relieve this Court of the task of satisfying itself that the appeal falls within the limited grant of jurisdiction in s 57(1) of the Land and Environment Court Act.
38The limitation on this Court's appellate jurisdiction in appeals such as this is long-standing. Formerly, no appeal lay from a determination of the value of land compulsorily acquired by the (former) Land and Valuation Court, except insofar as a party could seek a case to be stated to the Supreme Court for decision on a question of law: Land and Valuation Court Act 1921 (NSW), s 17. Of all the members of the Court in Turner v Minister of Public Instruction [1956] HCA 7; 95 CLR 245, it was Dixon CJ who gave the closest consideration to that jurisdictional limitation. His Honour said at 267:
"It is therefore only questions of law which the Supreme Court has jurisdiction to decide for the purpose of reviewing a determination of compensation or value. No doubt at the foundation of the present case lies the criterion of value for which Spencer v The Commonwealth (1907) 5 CLR 418 has been so frequently cited. But it by no means follows that the modes of reasoning employed in applying the criterion are matter of law."
39Dixon CJ also said (at 268):
"But what matters for present purposes is first that valuation cannot be made to depend entirely on a logical process or formula and second that in any case questions of logical reasoning about considerations of fact are not to be confused with questions of law."
40The first difficulty with Sydney Water's submission is the same as that identified above: it is difficult, to say the least, to maintain that a particular sale is comparable, but to contend that an adjustment to it involves error of law. I do not regard what his Honour did as irrational. The essential task was to extrapolate from a relatively high per square metre rate from the sale of a small (originally residential) lot, in order to determine the diminution in value of a larger lot (some one hundred and thirty fold larger), only around one twentieth of which was affected by the easement. Some discount is required. There can be no suggestion of any precise mathematical relationship between relative size and the discount. To the extent that there be error (I am not suggesting there was any), it is not error of law.
41At the forefront of its written submissions, Sydney Water pointed to the fact that the approach adopted by the primary judge was "of significance not just in this case but more generally". The submission was elaborated orally:
"But the fact that [the before and after, and piecemeal, methodologies] are so prominent and regularly applied as methodologies, should incline the Court to identify the true error of principle in the application of one of those methodologies as an error of law within s 57 because it is apt to operate as a principle that will be picked up in subsequent cases and so on, and a statement of valuation principle in that sense can have some ongoing effect as though it were a principle of law or a principle by which to exercise the statutory power to determine compensation."
42That submission would be apt if an appeal lay but only by leave. It might also find favour in the United Kingdom, for a different reason. There it has been said what is a question of law depends on "whether as a matter of policy one thinks that it is a decision which an appellate body with jurisdiction limited to errors of law should be able to review": Lawson v Serco [2006] UKHL 3; [2006] 1 All ER 823 at [34], where Lord Hoffmann echoed what had been said in Moyna v Secretary of State for Work and Pensions [2003] UKHL 44; [2003] 4 All ER 162 at [26]-[27]. Most recently, these principles have been confirmed in Jones v First-tier Tribunal [2013] UKSC 19; [2013] 2 AC 48 at [16] and [42]-[46]. In New Zealand, Elias CJ has expressed attraction to a similar view in Vodafone, Telecom, Commerce Commission [2011] NZSC 138 at [16] but cf the approach adopted by Blanchard, McGrath and Gault JJ.
43There is no universally satisfactory test for defining an error of law: Collector of Customs v Agfa-Gevaert Ltd [1996] HCA 36; 186 CLR 389 at 394. What in any particular case amounts to an error of law depends on context: see for example Attorney-General (NSW) v X [2000] NSWCA 199; 49 NSWLR 653 at [25]-[44] especially at [37]. However, there is no suggestion of which I am aware that the decisions of the House of Lords and the United Kingdom Supreme Court referred to above reflect the law of Australia. To the contrary, the British emphasis on expediency and policy is at odds with the focus on the particular statutory language emphasised in Kostas v HIA Insurance Services Pty Ltd [2010] HCA 32; 241 CLR 390 at [89], as well as with what is said in this context by Professor Aronson under the (aptly evocative) heading "Cynical reductionism unacceptable" in M Aronson and M Groves, Judicial Review of Administrative Action, 5th ed Lawbook Co 2013, pp 196-198. Moreover, considerable care is required when seeking to apply decisions of United Kingdom courts on "error of law" and "question of law", since essentially all errors of law are jurisdictional in the United Kingdom, while Australian law insists upon maintaining a distinction between jurisdictional error and non-jurisdictional error of law on the face of the record.
44In any event, to respond to Sydney Water's submission on its merits, this was a very unusual application of valuation principles. It is not likely that the available comparable sales in most valuation cases will require so much adjustment and extrapolation as was required in the present case.
45Sydney Water submitted that the primary judge erred in relying on what Lloyd J had said in Penrith City Council v Sydney Water Corporation [2009] NSWLEC 2 at [10]-[13] in rejecting its submission that a discount referable to the whole of Lot 306 should have been applied to the sales of (formerly) residential land. I acknowledge that there in force in the submission that the reasoning of Lloyd J is not directly applicable to the acquisition of an easement over part of a large lot, as opposed to the acquisition of the whole of an existing lot. But even if Sydney Water's submissions be taken at their highest, his Honour was faced with an acknowledged need to discount the per square metre value of the sales of the (formerly) residential land, as but one element in a long process of applying an agreed methodology. Council's valuer favoured a discount of 20%; Sydney Water's valuer favoured a discount of 70%. Even if part of the reasoning supportive of his Honour's adoption of Council's valuer's opinion in this respect disclosed an erroneous understanding of a decision relied upon, there is no error of law. As Dixon CJ said, the process is not entirely logical, and questions of logical reasoning about considerations of fact must not be confused with questions of law.
46Finally, Sydney Water submitted that the reasoning of the primary judge disclosed error of law because it was contrary to s 56(1)(a) of the Land Acquisition (Just Terms Compensation) Act 1991 (NSW). It was said that:
"The rate per square metre that the primary judge considered appropriate to apply to the land affected by the easements was increased from the rate that would have been applicable to Lot 306 generally because the land under the easements has a much smaller area than Lot 306 generally, which was itself a consequence of the acquisition and therefore required to be disregarded."
47Had the primary judge had regard to any increase or decrease in the value of the land caused by the acquisition of the easement, and had that been material to the determination of compensation, then error of law would have been disclosed. However, it is sufficient to say that Sydney Water's submission does not accurately characterise the approach taken by the primary judge, as may be seen from what is set out earlier in these reasons.
48It is to be kept firmly in mind that the task required to be undertaken was difficult. The easements were located on a highly unusual parcel of land. It is utterly unsurprising that there were no closely comparable sales. It is plain that the primary judge fully appreciated the limitations of the different sales propounded by the parties, and endeavoured, in a way that was transparent and rational, albeit undoubtedly contestable, to bring points of distinction to account. In so doing, no error of law is disclosed.
49The appeal and the cross-appeal should be dismissed. An order which fairly reflects the absence of success of any moving party, as well as avoiding the scope for disputation as to costs between them, is that there be no order as to costs, with the intention that each party bear its own costs of the appeal and of the cross-appeal.
50Accordingly, I propose these orders:
- Appeal dismissed.
- Cross-appeal dismissed.
