Grounds 1 and 2
35 The taxpayer argued that the Tribunal and the Court below took the same wrong approach to the question of the validity of the 2012 assessments by "commen[cing] with the well-established principle that a nil assessment is not an assessment, and the proposition that because there had only been nil assessments for 1998 and 1999 there was nothing to amend". It was submitted that "this entailed reasoning backwards to the conclusion that because the decision maker could not have validly made amended assessments the decision maker must therefore have made original assessments". The taxpayer contended that this reasoning imputed to the decision maker the exercise of a statutory power that the decision maker should have exercised or could have exercised, not the power that was in fact exercised by the decision maker in making the assessments. On the taxpayer's argument, the correct approach was to determine the statutory power that was exercised "as a matter of historical fact" and then to proceed to consider whether that exercise of power was valid. It was submitted that the exercise of power under s 170 of the 1936 Act was not valid because, so the argument went, there was no authority to make the amended assessment in the absence of original assessments for those income years. In our opinion, these submissions are wholly misplaced, and are to be rejected for the following reasons.
36 First, the Commissioner's power to make an amended assessment is separate and distinct from his power to make an original assessment. The power to make amended assessments and the preconditions for the exercise of that power are contained in s 170 of the 1936 Act. Where a prior assessment has been made for that income year, an assessment which operates to alter the prior assessment is an amended assessment: s 170. Where there has been no prior assessment for an income year, an assessment will be an original assessment for that year. The relevant question therefore is the nature of the 2012 assessments. That question is not answered by the form of the notices but what the Act requires as constituting an amended assessment, namely the alteration or addition to an assessment: see 170(1). In the present case, s 170(1) was only engaged as an exercise of power by the Commissioner if the 2012 assessments effected the amendment of any assessment. This is supported by Lever Bros Pty Ltd v Federal Commissioner of Taxation (1948) 77 CLR 78 which, contrary to the appellant's submission, is direct authority on this point. In that case, Williams J held that the time limits in s 170 of the 1936 Act for making amended assessments did not apply to assessments which were referred to in the notices as "amended assessments" because those assessments, though called amended assessments, were, in law, original assessments. The case is also authority that the misdescription of a notice of assessment as an amended assessment is an irregularity covered by s 175 of the 1936 Act. The primary judge correctly held that the Tribunal had to characterise the subject matter of the objection decisions in order to determine whether the Commissioner had made original or amended assessments and that the Tribunal carried out that task consistently with authority, and correctly.
37 Secondly, the primary judge correctly rejected the appellant's argument that the notices issued were "definitive of the administrative decision" the Commissioner made. The Tribunal correctly reasoned on the authority of FCT v Ryan that s 170(1) was not engaged. Under the law as it stood in relation to the 1998 and 1999 income years, an assessment within the meaning of the 1936 Act was not made until the Commissioner had served notice on the taxpayer of a positive amount of tax that was due and payable: Batagol v Federal Commissioner of Taxation (1963) 109 CLR 243 at 253; FCT v Ryan. As the taxpayer had returned $0 taxable income for both the 1998 and 1999 income years, no tax had become due and payable in respect of those income years. Accordingly, there had been no prior assessment of the taxpayer in respect of those income years. The only question for the Tribunal then was whether s 171A precluded the making of those assessments.
38 Thirdly, the primary judge correctly held that Danmark v Federal Commissioner of Taxation (1944) 7 ATD 333 and Federal Commissioner of Taxation v Wade (1951) 84 CLR 105 on which the taxpayer relied do not assist its case. The taxpayer argued that those cases were authority that an assessment made under one assessment provision of the 1936 Act cannot be supported under a different assessment provision and, so the argument went, the assessments could not be supported on "the new basis" as exercises of the power to make original assessments. Contrary to the taxpayer's submissions, those cases do not stand for the proposition advanced. As the Court below correctly pointed out, both cases were dealing with a different issue: namely, whether the Commissioner, in appeal and review proceedings, should be allowed to support the correctness of an assessment of a taxpayer's tax liability on a basis that was not relied on by the Commissioner in making the assessment where, in the statutory regime then applying to the appeal and review process, a taxpayer was confined to the grounds stated in that taxpayer's objection and had no opportunity to object on the new basis on which the Commissioner sought to rely to support the assessment.
39 Fourthly, s 177(1) of the 1936 Act also does not assist the taxpayer. Section 177(1) provided that the production of a notice of assessment or of a copy:
… shall be conclusive evidence of the due making of the assessment and, except in proceedings under Part IVC of the Taxation Administration Act 1953 on a review or appeal relating to the assessment, that the amount and all the particulars of the assessment are correct.
40 The taxpayer argued that s 177(1) gave conclusiveness to the due making of the notices of amended assessments as assessments made by the exercise of power under s 170 and therefore, it was argued, the Tribunal was bound to find that the assessments were amended assessments. The Court below also correctly rejected this argument. It is well established law that the conclusive evidence provision in s 177(1) does not apply in Part IVC proceedings: Federal Commissioner of Taxation v Futuris Corporation Ltd (2008) 237 CLR 146 ("FCT v Futuris") at [64]. In such proceedings, the issue is whether the amount assessed is excessive: Federal Commissioner of Taxation v Dalco (1990) 168 CLR 164. In reviewing or determining an appeal against an objection decision, the Tribunal or the Federal Court (as the case may be) applies the provisions of the Act governing the ascertainment of the taxpayer's taxable income and tax liability and, in the application of those provisions, the "conclusive evidence" provision in s 177(1) has no operation: Deputy Commissioner of Taxation v Richard Walter Pty Ltd (1995) 183 CLR 168; McAndrew v Federal Commissioner of Taxation (1956) 98 CLR 263 at 282 to 283. In the present case, the nature of the assessments as original or amended assessments was not protected from challenge by s 177(1).
41 The taxpayer's appeal against the dismissal of the s 39B application must also fail. The contention that the assessments, if original assessments, were not legally effective because it was beyond the power of the Commissioner to make those assessments under s 170 is answered by s 175 of the 1936 Act. As the High Court explained in FCT v Futuris at [64] to [70], the effect of s 175 and s 177 is that the validity of an assessment is only capable of being impugned in proceedings under s 39B of the Judiciary Act where the assessment is tentative or provisional (for example Federal Commissioner of Taxation v Hoffnung & Co Ltd (1928) 42 CLR 39) or where it is the product of conscious maladministration: that is, deliberate failure to administer the law according to its terms. No such jurisdictional ground was alleged or relied upon by the taxpayer in the present case.
42 Federal Commissioner of Taxation v Bayly (1952) 86 CLR 506 and Federal Commissioner of Taxation v Prestige Motors (1994) 181 CLR 1 on which the taxpayer relied in support of its relief under s 39B do not require any analysis. They were not cases brought under s 39B. Moreover, by reason of s 175, the validity of an assessment is not affected by failure to comply with any provision of the 1936 Act. Errors in the process of assessment do not go to jurisdiction and so do not attract the remedy of a constitutional writ under s 39B of the Judiciary Act: FCT v Futuris.
