Are the Current Proceedings Precluded by Issue Estoppel?
50 The primary judge also found that the appellants are estopped according to the doctrine of issue estoppel from contending that the interest incurred by Spassked in the 1991, 1993 and 1994 years of income was incurred in gaining or producing assessable income or necessarily incurred in carrying on a business for the purpose of gaining or producing assessable income.
51 His Honour referred to and quoted the passages in the reasons for judgment of Dixon J in Blair v Curran (1939) 62 CLR 464 at 532 - 533:
"Nothing but what is legally indispensable to the conclusion is thus finally closed or precluded. In 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. Where the conclusion is against the existence of a right or claim which in point of law depends upon a number of ingredients or ultimate facts the absence of any one of which would be enough to defeat the claim, the estoppel covers only the actual ground upon which the existence of the right was negatived. But in neither case is the estoppel confined to the final legal conclusion expressed in the judgment, decree or order … the judicial determination concludes, not merely as to the point actually decided, but as to a matter which it was necessary to decide and which was actually decided as the groundwork of the decision itself, though not then directly the point at issue. Matters cardinal to the latter claim or contention cannot be raised if to raise them is necessarily to assert that the former decision was erroneous.
In the phraseology of Lord Shaw [in the course of his Lordship's dictum in Hoysted in the Privy Council hereafter referred to and discussed], 'a fact fundamental to the decision arrived at' in the former proceedings and 'the legal quality of the fact' must be taken as finally and conclusively established (Hoysted v. Commissioner of Taxation [[1926] AC 155]). But matters of law or fact which are subsidiary or collateral are not covered by the estoppel. Findings, however deliberate and formal, which concern only evidentiary facts and not ultimate facts forming the very title to rights give rise to no preclusion. Decisions upon matters of law which amount to no more than steps in a process of reasoning tending to establish or support the proposition upon which the rights depend do not estop the parties if the same matters of law arise in subsequent litigation."
52 Before the primary judge the appellants' principal contention was that the doctrine of issue estoppel could not apply in revenue cases, where the assessments are for different years of income: at [119] and [124] of his Honour's reasons below. A similar submission was made on the appeal by reference to the following matters:
(1) The words of Spencer Bower, Turner and Handley (Res Judicata, 3rd Edition) at 300:
"Decisions on income tax, land tax and ratings assessments constitute an established exception to the general rules as to res judicata. Decisions on one year's tax or rate … do not create estoppels in respect of another year's tax or rate … The liability of the taxpayer for a subsequent year's tax or rate is not strictly the same question as his liability for an earlier year, even where no material circumstance has changed."
(2) In the appellants' submission, the better view is that the so-called "exception" thus described is in reality not an exception at all, but an example of the operation of the ordinary rule. That is to say, the fact that a person's tax liability in one year is a different question from the person's tax liability in another year, simply means that basis for the operation of the rule does not exist. The fact that the matters decided in revenue cases are limited means that the operation of the ordinary rule is correspondingly limited.
(3) The decision of the Privy Council in Broken Hill Proprietary Co Ltd v Municipal Council of Broken Hill (1925) 37 CLR 284, the decision of the House of Lords in Society of Medical Officers of Health v Hope [1960] AC 551, the decision of the Privy Council in Caffoor v Commissioner of Income Tax, Colombo [1961] AC 584, the apparent approval of Caffoor in the joint judgment of Deane, Toohey and Gaudron JJ, with whom Brennan J agreed, in Chamberlain v Deputy Commissioner of Taxation (1988) 164 CLR 502 at 510 and finally what was said by Merkel J in Orica Ltd v Federal Commissioner of Taxation (2001) 182 ALR 77 at 87:
"Issue estoppel has been held not to apply to a taxpayer where the previous decision relied upon as founding the issue estoppel related to a different year of income. Although there was some support for the contrary view in Hoysted v. Commissioner of Taxation, that decision was not followed in Caffoor v. Commissioner of Income Tax Colombo. In Caffoor the Privy Council determined that a taxpayer is not estopped from contending that it was entitled to an exemption in respect of a year of income by a decision in respect of a different year of income. More recently, in Chamberlain v. Deputy Commissioner of Taxation, Deane, Toohey and Gaudron JJ cited Caffoor as authority for the proposition that 'the Commission is not bound by the determination made in respect of an assessment for one year, so far as other years are concerned.' It must follow that the Commissioner's issue estoppel argument also fails."
53 At [106] of his reasons, the primary judge observed that, in his view, the context and circumstances of the current proceedings are significantly distant and removed from those of the authorities relied upon by the appellants, in particular, Broken Hill, Hope and Caffoor,such as to render those authorities of no sufficient assistance here to the appellants as judicial precedents. Based on what was said in the joint judgment of Rich, Dixon and McTiernan JJ in Falk v Haugh (1935) 53 CLR 163 at 171, the primary judge further observed that there is at least something plausible to be said for the view that Broken Hill and Hoysted are susceptible to reconciliation, and in any event, that Hoysted should be preferred to the extent of any inconsistency. His Honour went on to observe that so much would be in line with the observations of the three members of the High Court in Queensland Trustees Limited v Commissioner of Stamp Duties (1956) 96 CLR 131 and that he did not think the appellants gained assistance of sufficient significance from the relatively brief citation of Caffoor appearing in the joint judgment of the High Court in Chamberlain. His Honour had earlier (at [74]) discounted what Merkel J said in Orica on the basis that the estoppel issue there was in the nature of an alternative contention and that Merkel J was not provided with the substantial scope of judicial references and analysis of authority that had been afforded to him by the parties.
54 The Commissioner, in his submissions on appeal, submitted that his Honour was correct in his analysis of the relevant and, in some cases, conflicting authorities and that he had correctly applied the doctrine of issue estoppel to the appellants.
55 One hesitates to part company with a judge of this Court with such experience and expertise in the fields of commercial and revenue law but, with the utmost respect to his Honour, I am unable to agree with his Honour's analysis of the relevant authorities and, if necessary, their reconciliation.
56 First and foremost, if any relevant authorities are distant and removed from the context and circumstances of the current proceedings then, in my view, they are Hoysted and Queensland Trustees, not Broken Hill, Hope and Caffoor.
57 The relevant issue in Broken Hill was the proper method for calculating the unimproved capital value of a mine for the purpose of determining a liability to tax for a certain year. A decision of the High Court in earlier litigation between the same parties, relating to the same tax, and the same mine, but a different tax year, had held that the correct approach to calculating value was one that was favourable to the local authority. Before the Privy Council, the taxpayer sought to argue that a different method of calculating the relevant value was appropriate. The Privy Council, in rejecting the Council's submission that the issue was res judicata, said (at 289):
"It was also contended before this Board on behalf of the respondents that, having regard to the said decision of the High Court of Australia, the question raised by this appeal is res judicata as between the appellants and the respondents, and the appellants are estopped from contending that such decision of the High Court of Australia is wrong … There is, however no substance in this contention. The decision of the High Court related to a valuation and a liability to a tax in a previous year, and no doubt as regards that year the decision could not be disputed. The present case relates to a new question, namely, the valuation for a different year and a liability for that year. It is not [eadem quaestio], and therefore the principles of res judicata cannot apply."
58 The effect of that decision was that the taxpayer was not estopped from arguing (before the Privy Council) that the decision of the High Court was wrong. The previous decision, relating to a different year of income, did not determine the tax liability for the later year of income.
59 Slightly more than a month later, a differently constituted Privy Council gave its advice in Hoysted. The issue in that case was a liability for land tax, the liability depending upon the number of "joint owners" holding "original shares". The Privy Council held that a prior decision of the High Court that the beneficiaries of a trust were "joint owners" was binding on the parties, and that the Commissioner could not, in subsequent years, dispute that fact. The Privy Council did not refer to its earlier decision in the Broken Hill Case.
60 The conflict between Broken Hill and Hoysted was considered by the House of Lords in Hope. The House of Lords followed Broken Hill. Lord Radcliffe (at 562 - 563) said:
"The system of rating involves certain considerations that are special to itself. Its nearest analogy is with the system of annual personal taxation. With regard to both one has to begin by recognising that there is a high and frequent authority for the proposition that it is not in the nature of a decision given on one rate or tax that it should settle anything more than the bare issues of that one liability and that, consequently, it cannot constitute an estoppel when a new issue of liability to a succeeding year's rate or tax comes up for adjudication.
It would not be at all easy for us to depart form this long line of authoritative opinion, even if we wanted to. Personally, I do not want to, because I think that, on the whole, it is more in the public interest that tax and rate assessments should not be artificially encumbered with estoppels (I am not speaking, of course, of the effect of legal decisions establishing the law, which is quite a different matter), even though in the result some expectations may be frustrated and some time wasted."
61 In relation to the conflict between Broken Hill and Hoysted, at 569 - 570 Lord Keith said:
"Much reliance was placed by counsel for the appellants on the judgment of the Privy Council in Hoysted v. Commissioner of Taxation. That authority is not binding on this House, and the point was never taken in the case that a decision on liability to assessment to tax for one year is not conclusive of liability to assessment in a later year. The judgment would seem to conflict with what was said a month earlier in Broken Hill Proprietary Co. Ltd. v Broken Hill Municipal Council by a Board differently constituted, rejecting a plea of res judicata: 'The decision of the High Court,' it was said, 'related to a valuation and a liability to take in a previous year, and no doubt as regards that year the decision could not be disputed. The present case relates to a new question - namely, the valuation for a different year and the liability for that year. It is not eadem quaestio, and therefore the principle of res judicata cannot apply.' In my opinion, that is the position here, and I do not find it necessary to examine Hoysted's case further, beyond observing that some of the things that were said in that case are not, I think, entirely consistent with what was said in New Brunswick Railway Co. v. British and French Trust Corporation Ltd., or with what I regard as essential to a successful plea of res judicata, a common medium concludendi in the two actions."
62 The Privy Council itself addressed the conflict the following year in Caffoor, overturning Hoysted. In Caffoor, the Commissioner sought to argue that a trust deed did not create a charity, despite that precise point having been determined adversely to the Commissioner in previous litigation between the same parties but relating to different years of income. The Privy Council held that the Commissioner was entitled to argue the point in the new proceedings, saying (at 598 - 599):
"It is in this sense that in matters of a recurring annual tax a decision on appeal with regard to one year's assessment is said not to deal with 'eadem quaestio' as that which arises in respect of an assessment for another year and, consequently, not to set up an estoppel. It is precisely that point that was raised and accepted by this Board in 1926 in Broken Hill Proprietary Co Ltd v. Broken Hill Municipal Council …
The Broken Hill decision is in itself a striking application of the principle involved, since the earlier judgment which it was sought to set up as an estoppel was one given by the High Court of Australia on a rating assessment referred to it by way of appeal under the tax procedure. It underlines the point that it is not the status of the tribunal itself, judicial or administrative, that forms the determining element for estoppel in cases of this kind but the limited nature of the question that is within the tribunal's jurisdiction. The judgment of the High Court that had been given in the earlier year was explicitly directed to the construction of a particular section of the rating Act and to the correct measurement of the liability in the light of that construction. Precisely the same point arose in the later year and ultimately decided by this Board in a sense contrary too that which had previously been adopted.
63 A little later (at 599 - 601) the Privy Council said:
"To apply the principle of the Broken Hill decision to the case now before their Lordships is to bring it into line with what seems to be by now the regular course of authority with regard to appeals in successive years against income tax or rating assessment …
The decision of this Board in Hoysted v. Commissioner of Taxationis not consistent with this line of authority, and the appellants naturally relied upon it in their argument. What happened in that case was that an assessment to federal land tax in Australia for the year 1918-19 had been the subject of appeal, and a case was stated for the opinion of the High Court on a point of law that determined the assessment, the correct interpretation of the taxing statute with regard to joint interests in land taken by the assessees under their father's will.
There was a later appeal in respect of the assessment for the year 1920-21; and the question that was brought to this Board was whether the Commissioner of Taxation was estopped in the matter of that assessment by the judgment that had been delivered by the High Court in the earlier proceedings. The Board decided that he was. Unfortunately, however, the argument that the determination of an assessment for one year could not set up an estoppel upon an assessment for another year, an argument that was accepted by the Board at almost the same time in the Broken Hill case, does not appear either to have been presented to the Board or to have been noticed or adjudicated upon in the opinion which was delivered by Lord Shaw. It is not possible to explain why the matter was dealt with in this way; and it is fair to note that in the majority judgment of the High Court, which was reversed on the appeal, there is a reference, though a passing one, to the point of 'eadem quaestio.' In the result, however, the attention of the Board in delivering its opinion was wholly occupied with a discussion of what is quite a different issue in connection with estoppel, whether there can in law be estoppel per rem judicatam in respect of an issue of law which, though fundamental to the issue, has been conceded and not argued in an earlier proceeding.
Their Lordships are of opinion that it is impossible for them to treat Hoysted's case as constituting a legal authority on the question of estoppels in respect of successive years of tax assessment. So to treat it would bring it into direct conflict with the contemporaneous decision in the Broken Hill case; and to follow it would involve preferring a decision in which the particular point was either assumed without argument or not noticed to a decision, in itself consistent with much other authority, in which the point was explicitly raised and explicitly determined."
64 Queensland Trustees involved a claim for succession duty on the footing that a will created certain trusts in respect of a property in favour of the deceased's two sons. Previously the Commissioner of Stamp Duties had successfully claimed stamp duty on an instrument of nomination of trustees of the property as a settlement. The issue estoppel which the High Court held precluded the succession duty claim was described by Dixon CJ at 138 in the following way:
"His [stamp duty] claim was contested but it was judicially declared by the Supreme Court that the nomination of trustees was chargeable with stamp duty as a settlement. That declaration was affirmed on appeal to this Court. Disregarding altogether the reasons for this decision it appears to me to be, or at all events to involve, a judicial determination between the Crown and the executors that it was the nomination of trustees (including therein the schedule) which created the trusts. In face of that determination the Crown cannot now turn about and claim successfully that it was the will and not that instrument which created the trusts. On that simple ground of issue-estoppel, the claim of the Commissioner of Stamp Duties must fail."
65 Dixon CJ did not refer to Hoysted and it was only fleetingly referred to by Webb J and in the joint judgment of Kitto and Taylor JJ in the following terms (at 151):
"The question whether the instrument was such a settlement was then litigated between the trustees and the commissioner by means of a special case. The Full Court of the Supreme Court answered the question in the affirmative, and its decision was affirmed by this Court on appeal. The argument is that, as a consequence of its success in those proceedings, the Crown, here represented by the commissioner, is now estopped from denying that the operative instrument which gave the sons the interests which fell into possession on 21st January 1954 was the nomination of trustees and schedule of trusts. The principle of law which is relied upon is that for which Hoysted v. Federal Commissioner of Taxationis the leading authority in the Privy Council."
66 Of course what was said by their Honours concerning Hoysted being "the leading authority in the Privy Council" was said prior to the Privy Council's rejection of Hoysted in Caffoor.
67 As I intimated at [56] above, my analysis of the cases in the context of the current proceedings leads me to the view that the cases of Hoysted and Queensland Trustees are more "distant and removed from" "the context and circumstances", to use the words of the primary judge, of the current proceedings, than the cases of Broken Hill and Caffoor. Queensland Trustees can be distanced and removed because the issue estoppel did not arise, as in the present case, in the context of different years of assessment, income or tax. Moreover, in the first proceedings, the issue was determined upon a construction of the relevant statute, the will and the inter vivos instrument of nomination not, as in the earlier proceedings in the present case, detailed findings of fact critical or indispensable to the conclusion on the ultimate substantive issue in the 1992 year of income. Hoysted can be also distanced and removed for this second reason; because the issue was determined upon a construction of the relevant statue not, as in the earlier proceedings in the present case, detailed findings of fact critical or indispensable to the conclusion on the ultimate substantive issue in the 1992 year of income.
68 Second, the matters I have pointed to as distancing and removing the significance of Hoysted and Queensland Trustees to the question of whether the determination of the ultimate substantive issue in the earlier proceedings in the present case create an issue estoppel in the current proceedings, equally focus attention on what is relevant to the resolution of this question. As Dixon J stated in Blair v Curren at 531 - 532, an issue estoppel arises only in relation to
"… those matters which the prior judgment, decree or order necessarily established as the legal foundation or justification of its conclusion … Nothing but what is legally indispensable to the conclusion is thus finally closed or precluded."
69 A number of the findings of fact in the earlier proceedings, including those going to the purpose of the borrowing and the application of the borrowed funds, relevant to the ultimate substantive issue in the earlier proceedings, namely, whether the interest incurred in the 1992 year of income by Spassked on the IEF loans was deductible under s 51(1) of the ITAA 1936, were "legally indispensable' to determination of that issue. But they were not, in my view, "legally indispensable" to the determination of the issue of whether the criteria for deductibility under s 51(1) of the ITAA 1936 was met in other years of income. There are at least four reasons for this.
70 First, the issue of deductibility of interest on the IEF loans in years of income other than the 1992 year of income was not before the Court in the earlier proceedings.
71 Second, the issue of deductibility of interest on a loan under s 51(1) is essentially a question of fact in respect of the year or years of income for which it is to be determined. Moreover, it is clear that the relevant factual considerations can change over the term of the loan so that the facts relevant to the criteria for deductibility in one year will not necessarily mirror those in another year. This is perhaps best brought out by Hill J in Kidston Goldmines Limited v Commissioner of Taxation (1991) 30 FCR 77 at 85 where his Honour said:
"In determining deductibility under s 51(1), reliance on the tests both of purpose of the borrowing and of application of the funds present difficulty. If the true test were confined to purpose of the borrowing, a taxpayer who borrowed funds for an income-producing purpose would continue to receive a deduction, notwithstanding that the income-producing activity had ceased. Such was shown not to represent the law in Commissioner of Taxation (Cth) v Riverside Road Lodge Pty Ltd (In liq) (1990) 23 FCR 305. Conversely, if funds were borrowed for a non-income producing purpose, eg to purchase a home in which the taxpayer resides, and later the home were let, no deduction would be available to the taxpayer for the interest payable, which is a direct cost of the income-producing activity of letting the house. A test of application of funds borrowed also presents difficulties. Where funds are borrowed with the intention that they be used to purchase, for example, a property for letting, and the proceeds of the borrowing are paid into a bank account from which funds are drawn both for the purchase and to satisfy non-income-producing outlays, a tracing of funds approach would require an apportionment of interest, yet it would generally be accepted that the taxpayer would be entitled to a deduction for the whole of the interest, at least provided that the equivalent to the amount borrowed found its way into the purchase of the income-producing asset.
This is not to say that tests such as the purpose of the borrowing or the use and application of the borrowed funds are irrelevant. Rather, they are tools to assist in the resolution of what is essentially a question of fact. To be deductible the outgoing, or in a case of apportionment a part of an indivisible outgoing, must be seen to be incidental and relevant to the activity which is directed to the gaining or production of assessable income. In the normal case, the fact that the funds borrowed have been borrowed for the purpose of that activity and can still, in the year of income in which the deduction is claimed, be seen as having that purpose will lead readily to the conclusion that the interest will be incidental and relevant to the income-producing activity. Again, in the usual case, the application of funds to an income-producing purpose will demonstrate the relevant connection between the outgoing and the income-producing activity. Indeed there is much to be said for the view that the tests of purpose and application of funds are but two sides of the one matter."
72 Third, as already indicated at [21], [26] and [32] above, the earlier proceedings were conducted by both parties and decided, both at first instance and on appeal, by reference to facts and circumstances falling within a temporal framework commencing on the date of the first borrowing, 30 December 1987 and expiring on the date of the last borrowing, 28 June 1990. Facts and circumstances occurring outside that period were not relied upon and even though there may have been findings of fact outside that period, they were not, in my view, legally indispensable to the conclusion on the ultimate substantive issue in the earlier proceedings.
73 Fourth, in the current proceedings, the appellants do not seek to rely on facts and circumstances falling within the temporal framework relied upon in the earlier proceedings in support of the conclusion they contend the Court should reach on the ultimate substantive issue in the 1991 year of income in the case of QTH, in the 1993 and 1996 years of income in the case of IEF and in the 1994 year of income in the case of Spassked.
74 For those reasons, I have reached the conclusion that the current proceedings are not precluded by issue estoppel.
