Disposition of the appeal
25 In our view, the taxpayer's first submission should not be accepted. The Tribunal's reasons need to be read as a whole and, when so read, we do not accept the submission that the Tribunal was excluding consideration of the Kompos report per se because it was not evidence led by the taxpayer. The Tribunal's essential reasoning on whether the taxpayer had discharged the burden of proof on him is, in our view, contained in paragraph [73] of its reasons (set out above). This paragraph followed extensive consideration of the cases dealing with the burden on the taxpayer to show that the assessment is excessive: see, in particular, paragraphs [36], [52], [62], [68]-[72] of the Tribunal's reasons. In paragraph [62], the Tribunal set out the following passage from the judgment of Brennan J in Commissioner of Taxation v Dalco (1990) 168 CLR 614 at 624:
If the Commissioner and a taxpayer agree to confine an appeal to a specific point of law or fact on which the amount of the assessment depends, it will suffice for the taxpayer to show that he is entitled to succeed on that point. Absent such a confining of the issues for determination, the Commissioner is entitled to rely upon any deficiency in proof of the excessiveness of the amount assessed to uphold the assessment, though the taxpayer is limited to the grounds of his objection.
26 The Tribunal set out, in paragraph [68], the following passage from the judgment of Kitto J at first instance in George v Federal Commissioner of Taxation (1952) 86 CLR 183 at 189:
But s 190(b) places the burden of proving that the assessment is excessive upon the appellant; and in order to carry that burden he must necessarily exclude by his proof all sources of income except those which he admits. His case must be that he did not derive from any source taxable income to the amount of the assessment. That will involve him, of course, in accounting for the increase in his assets, and it may well be that the commissioner will direct his efforts mainly or even wholly to endeavouring to meet the evidence the appellant adduces on this point. But the source of the increase in the assets is not the actual issue in the case; even if it were proved, for example, that that source consisted of winning bets on the racecourse, the issue would still be whether or not from any source the appellant derived as much taxable income as the assessment treats him as having derived.
The object of the present application is really to have the commissioner say whether he is prepared to assign a source or sources for the moneys included in taxable income in the assessment over and above those disclosed as taxable income in the return, and to admit that if they did not come from that source, or from one or more of those sources, those moneys were not liable to be included in the appellant's taxable income. The commissioner may, if he chooses, voluntarily narrow the possible range of evidence in that way, but there could be no justification for ordering him to do so, under the guise of ordering particulars. If he attempts to prove derivation from a particular source and fails, he is none the less entitled under the Act to point to another source, or, without troubling about source at all, to stand upon his assessment and submit that the presumption in its favour has not been displaced.
27 In paragraph [69], the Tribunal set out the following passage from the judgment of Dixon CJ, McTiernan, Williams, Webb and Fullagar JJ in George v Federal Commissioner of Taxation (1952) 86 CLR 183 at 201:
The word "assessment" is defined by s 6(1) to mean the ascertainment of the amount of taxable income and of the tax payable thereon. In conformity with this definition s 166 directs the commissioner to make an assessment of the amount of the taxable income of any taxpayer and of the tax payable thereon. From these provisions both in their present form and in their slightly different earlier form, the law has always been taken to be that in an appeal from an assessment the burden lies upon the taxpayer of establishing affirmatively that the amount of taxable income for which he has been assessed exceeds the actual taxable income which he has derived during the year of income: … "The justice of that burden cannot be disputed. From the nature of the tax, the commissioner has, as a rule, no means of ascertainment but what is learnt from the taxpayer, and the taxpayer is presumably and generally, in fact, acquainted with his own affairs. The onus may prove to be dischargeable easily or with difficulty according to the circumstances", per Isaacs ACJ, Federal Commissioner of Taxation v Clark.

28 Then, in paragraph [72], the Tribunal said:
Given the above authorities, in the absence of the Commissioner's consent to confine the issues for determination to the assessment of partnership income as set out in Mr Kompos's report, Mr Rigoli's claim to rely on Mr Kompos's report cannot be sustained. The Commissioner has not agreed to confine the issues for determination to the partnership income as assessed by the Commissioner's expert, Mr Kompos, and in fact, to the contrary, has insisted that Mr Rigoli discharge the onus of proving that the assessment was excessive by establishing his actual income from all sources, not solely the partnership. Even if the Commissioner had agreed to confine the issues in this case to Mr Rigoli's assessable income, Mr Rigoli would not discharge his onus of proof by simply referring to the Kompos report.
(emphasis added)
29 In the context of these passages, paragraph [73] of the Tribunal's reasons is to be understood as saying, not that the taxpayer could not rely on the Kompos report because it was not evidence led by the taxpayer, but rather that it was insufficient to discharge the burden on the taxpayer of establishing his actual taxable income. The Tribunal acknowledged in paragraph [73] that "a taxpayer can discharge the burden of proof in a manner which may depend on the circumstances". The statement that "Mr Rigoli did not adduce any evidence of the amount or source of his income for any [of] the income years in issue" was merely recording the fact that the taxpayer had not, through his own evidence, sought to establish his actual taxable income from all sources; it was not saying that such evidence needed to be adduced by him. The essence of the Tribunal's reasoning is captured in the last sentence of paragraph [73], where the Tribunal said that the Kompos report "was not intended to and did not establish, even on the basis of an estimate, the actual taxable income of Mr Rigoli from all sources for the income years in question". That sentence makes clear that the Tribunal was not excluding the report from consideration because it was not evidence led by the taxpayer, but rather was saying that it was insufficient to establish his actual taxable income from all sources.
30 The Tribunal's conclusion that the Kompos report did not seek to, and did not, establish the taxpayer's actual taxable income from all sources is consistent with its earlier comments (in paragraphs [18]-[21] of its reasons) about the scope and methodology of the Kompos report, and the inherent limitations of the report due to the lack of information available to the expert. The Tribunal found that the Kompos report was merely the expert's best estimate, based on the information available to him, of the partnership's financial position for the years in question.
31 In relation to paragraphs [84] and [86]-[88] of the Tribunal's reasons, when these paragraphs are read as a whole and in context, in our view, the Tribunal was not excluding the Kompos report from consideration because it was not led by the taxpayer, but rather saying that it was insufficient to discharge the burden on the taxpayer. For example, in paragraph [84], the Tribunal said: "Although Mr Kompos provided a thorough but inexact assessment of what he considered Mr Rigoli's partnership income might have been in the years in question, that does not assist Mr Rigoli." Read in context, the Tribunal was saying that the report did not seek to, and did not, establish the taxpayer's actual taxable income from all sources. That is why it did not assist the taxpayer. In the last sentence of paragraph [84], the Tribunal said: "Mr Rigoli was unable to discharge the onus of proving that the assessment was excessive because he did not lead evidence of his actual income from all sources." In the context of what had come before, the point the Tribunal was making was that the taxpayer had not sought to establish his actual taxable income, not that such material needed to be led by him.
32 In paragraph [86], while the Tribunal states that it is "clearly essential" that the evidence be "produced" by the taxpayer, we think this is a reference to the production of sufficient information and documents from which the taxpayer's actual taxable income can be established. The statement, read in the context of the reasons generally, is not addressing whether the evidence relied upon in a proceeding needs to be led by the taxpayer rather than by the Commissioner. In our view, paragraph [88] does not support the taxpayer's submission; to the contrary, read in context it makes clear that the Tribunal was saying that the Kompos report did not seek to establish the actual taxable income of the taxpayer, and therefore was insufficient to discharge the burden on him.
33 For these reasons, which are largely the same as those of the primary judge in relation to the same submission put below, we do not accept the taxpayer's first submission.
34 In relation to the taxpayer's second submission, in our view, the Tribunal's conclusion that the Kompos report was insufficient to establish the taxpayer's actual taxable income from all sources was a finding of fact which it was open to the Tribunal to make. We have set out above paragraphs [18]-[21] of the Tribunal's reasons, which contain the Tribunal's findings in relation to the scope, methodology and inherent limitations of the Kompos report. As has been noted, the Tribunal concluded in paragraph [73] that the Kompos report "was not intended to and did not establish, even on the basis of an estimate, the actual taxable income of Mr Rigoli from all sources for the income years in question". It was open on the material for the Tribunal to conclude that the material relied on by the taxpayer was insufficient to discharge his burden of proof. It has not been shown that the Tribunal adopted an incorrect approach as to what the taxpayer needed to prove to discharge his burden of proof. We agree with the conclusion of the primary judge, in paragraph [10] of his Honour's reasons (see paragraph [17] above), that the Tribunal found, as it was entitled to find on the material before it, that the Kompos report, and its methodology, was incomplete and did not establish the taxpayer's income.
35 We note for completeness that the taxpayer relied, in his submissions on appeal, on Ma v Commissioner of Taxation (1992) 37 FCR 225 at 232-233, Martin v Federal Commissioner of Taxation (1993) 27 ATR 282 at 286-287 and Kimche v Federal Commissioner of Taxation (2004) 57 ATR 28, regarding ways in which a taxpayer may prove that an assessment is excessive. The Tribunal considered these decisions in paragraphs [81]-[84] of its reasons. The approach taken by the Tribunal was not inconsistent with the passages in these cases relied on by the taxpayer on appeal.
36 Given these conclusions, it is unnecessary for us to deal with the Commissioner's notice of contention.
