119 The need to consider the broad scope of appropriate directions remains, since the primary judge expressed concern on the matter in the context of a Crown case that includes particular N(v).
120 The parties were agreed before us that it was open to the trial judge to direct the jury that the private rulings favourable to taxpayers were (in their words) "arguably wrong" when issued. I have already explained that this formulation may cover two separate areas and have concluded that the count is not to be withheld from the jury because the rulings were incontrovertibly correct.
121 What remains as regards directions needing to be given stemming from Particular N(v)? Ex hypothesi the trial judge will have satisfied himself that the rulings were not incontrovertibly correct in law when issued, this satisfaction stemming from considering the evidence and the legal materials (see further below). Merely because N(v) is a particular of the Crown case does not however oblige the judge to direct the jury on the specific matter in the sense of inviting them to find arguability in law. If that issue is itself one of law, then the judge should direct the jury appropriately, not necessarily in those terms.
122 [As the Chief Justice and Hunt AJA point out], such a direction may well be subject to various permutations and combinations of the factual matters. The more usual form of directions to a jury - and the infinitely safer one - is to define the issue which the jury must determine, then explain to them the arguments of both parties in relation to the relevant factual material, and then conclude that, if the Crown has satisfied them that it has established that particular issue, they may move on to the next issue. None of this, it seems to me, requires the jury having to be instructed that they have to decide whether the rulings were "arguably wrong" as distinct from having to be instructed as to how they imperilled the revenue through the particular private rulings and the legal and practical effects of such rulings.
123 I do not accept Mr Temby's submission that the matter is answered in a favour of a direction in law by pointing to the complexity of the issues involved. There are pockets of caselaw where this factor may have contributed to the recognition of a specific universal rule (for example, as regards the "materiality" factor in perjury and false swearing: see R v Davies (1993) 7 SASR 373 at 388-394, R v Cassell (1998) 45 NSWLR 325). No authority supports the creation of a new category for taxation matters. Tax fraud trials have been part of the legal landscape for many years. A properly instructed jury is able to understand the legal tax principle said to have been dishonestly violated and to form its own opinion as to whether the requisite fraudulent conduct has occurred.
124 But the present situation is different, in my view. The matter to be determined is whether the private rulings were, in the language of Particular N(v), "arguably wrong" (in law) when issued. In the specific context of FBT this matter can be stated thus: was it open in law at the time for the ATO to argue that employees were "associates" within the legal provisions and principles stated by Mr Chow in his Initial Opinion of 25 March 1998 as adopted and reinforced by the respondent's views stated in his email of 15 April 1998?
125 This concept of being "legally arguable" or open is, in my view, a matter of law. It does not matter that the question is asked about an identified time in the past (here, relevantly, before Essenbourne was decided). Accordingly, it is something that the trial judge (if satisfied as to such "arguability") should direct the jury with his authority as the arbiter of matters legal. In the final analysis, it is no different from telling the jury that if facts A, B and C are established it is open for the jury to find X. Here "X" is that the revenue was put as risk by the rulings (if they were made as alleged).
126 It seems to me that a mixed question of fact and law is involved (see also Petroulias (No 2) at [46]).
127 Whether or not a particular transaction has particular tax consequences depends on locating the applicable law (statute and general law) and correctly applying it to the essential elements of the transaction. Minds may differ as to the legal consequences, but that is an inevitable aspect of a legal system administered by human agents. This does not relieve a judge from deciding, identifying and applying the relevant law to legal questions. It is not the jury's competence or task. If the judge errs, correction is at hand through the agency of the Court of Criminal Appeal and the High Court. Subject to the proviso, legal error in admitting or excluding evidence or in directing a jury will be corrected by appellate processes.
128 The judge's role is to give necessary and helpful legal directions to the jury. The distinction between matters of fact and matters of law is not always clear. It is, however, well established that the judicial duty encompasses directing the jury about relevant statutory and common law principles. That duty extends necessarily to relating those directions to the facts available to be found by the jury.
129 The law understands that some legal propositions can be stated with certainty whilst others cannot. Matters may change over time, such that what is certain in one era may be problematical in another. To give an example: when Sir Matthew Hale's History of the Pleas of the Crown was published in 1736, the common law was quite clear that a husband could not be guilty of raping his wife. The situation was arguable in the 1980s, but became clear again (to the opposite effect) after 1991 in light of The Queen v L (1991) 174 CLR 379 and Regina v R [1992] 1 AC 599.
130 An expert witness or a judge who is called upon to form a view about the certain or uncertain state of the law at a particular time in history, or its application in law to particular facts, may need to inform himself or herself by reading caselaw, legal digests, textbooks, legal encyclopaedias and law journals. Some may have sufficient legal experience in the matter at hand to trust their own "judgment" on the matter. Either way, the legal expert will often have to apply that knowledge to a particular set of proven or hypothetical facts. Such application is itself a legal function, because it is law that answers issues of relevance and capacity to reach certain conclusions.
131 A judge can therefore direct a jury that a statute or contract means X. If relevant, the judge can also direct the jury that the relevant law on the subject is either A or B, with the consequence that when applied to a situation or contract the result is X (or X or Y as the case may be). An analogy is the situation where the jury is told that it is "legally open" for them to decide A or B, but not C.
132 Not every application of a legal standard to a particular problem involves a question of law. But the issue whether a particular tax outcome was available, a fortiori arguable, is a matter of law (see generally Vetter v Lake Macquarie City Council (2000) 202 CLR 439 at 450[24]). Mr Chow's discussion about whether, on the assumed facts, an employee is arguably an "associate", with FBT consequences, appears to me to entail a sharp legal issue. It is not quite so clear with the deductibility issue because factual inferences of intent may be open, although I perceive that identical fact scenarios were provided on behalf of all applicant "Rulees".
133 I have already indicated that the putative vice of the respondent's private tax rulings was that they restricted the Commissioner's capacity to act against the taxpayers concerned otherwise than as represented in the rulings (cf Petroulias (No 1) at [64]). Viewed this way, the risk or imperilment was the tying of the Commissioner's hands in 1998, restricting his capacity to contend against favoured "Rulees" that the situation was other than as represented in their rulings.
134 It follows from what I have already written that it would be open to the trial judge to inform himself of the state of tax law as it stood when the rulings were issued. If that state of law permitted the Commissioner genuinely to advance a tax outcome in either or both of two tax issues otherwise than as embodied in the taxpayer-favoured rulings promoted by the respondent, then the judge could so direct the jury. The jury would then be directed that, if the factual elements of the Crown case were established, it would be open for them to find the necessary imperilment of the revenue of the Commonwealth. This is the ultimate fact in issue (along with dishonesty).
135 This approach avoids using "arguably wrong" as part of the direction to the jury. But it does mean that the "aggravated" Crown case goes to the jury if the judge has the requisite satisfaction that an aggravated case as alleged is open in law and on the facts. If it is, the judge may craft a direction addressing the elements of the count itself.
136 As indicated above, the ATO internal emails and memoranda summarised above are capable of being read as containing admissions by the respondent that are at least arguably consistent in 1998 with "the law" applied to the facts hypothesised as the judge may be persuaded to find it. Indeed, the judge may be assisted by the "chapter and verse" about the critical issue of the meaning of "associate" in s 26AAB(14)(a)(iv) of the Income Tax Assessment Act in the Chow memorandum, apparently adopted as correct by the respondent.
137 The judge may also draw assistance from case law both before and after the rulings in question (see further below as to Essenbourne). Of course, everyone knows that it is easy to be wise after the event, even in matters legal. Some cases apply settled law, some others settle the law, others unsettle the law. In the present case the critical point of time is when the rulings were issued, because they are the events said to have put revenue at risk. It also needs to be borne constantly in mind that the relevant imperilment under the present formulation of the count is the prejudice to the capacity of the ATO to act contrary to the position of the rulings against "Rulees" who received the favourable rulings. That prejudice stemmed from the law and practice touching private rulings. It existed unless the rulings were incontrovertibly correct when given.
138 I have come down on the legal side of the fence in the sense that I consider it to be a matter for the trial judge to make up his or her mind on the legal issue as I have sought to explain it. But the legal issue is a very narrow one: there are critical and associated factual issues that must be left to the jury, along with the ultimate issue of finding the matters averred in the count beyond reasonable doubt.
139 This does not mean that the judge can necessarily avoid explaining to the jury the legal issues canvassed in the ATO emails, especially the Chow opinion. An understanding of these matters may be important in evaluating the respondent's role in procuring the rulings as well as assessing the separate dishonesty factor. This will not however entail asking the jury to form their own view about the correspondence between the rulings and the true tax position at the time.
Essenbourne and later decisions of the Federal Court
140 Essenbourne Pty Ltd v Commissioner of Taxation [2002] FCA 1577, 51 ATR 629 and later decisions including Walstern v Commissioner of Taxation [2003] FCA 1428, 54 ATR 423, Spotlight Stores Pty Ltd v Commissioner of Taxation [2004] FCA 650, 55 ATR 745 and PrideCraft Pty Ltd v Commissioner of Taxation [2004] FCAFC 339, (2005) ATC 4001 might put an end to the "arguability" of certain propositions for the future. It may be going too far to say that these cases show that the position advanced by the ATO to the Federal Court in those cases was "arguable", whether or not it was accepted. But it would be fallacious to infer that an ATO-adverse decision in the Court established that the propositions there advanced by the Commissioner were untenable and unarguable then or at an earlier point of time.
