Allowing the appeal - but leaving the Tribunal's decision to stand?
44 Separate from any consideration as to the change in circumstances, the primary judge erred in failing to set aside the decision by concluding that the Tribunal had the ability to invoke s 43AA of the AAT Act to rectify the deficiencies in its reasons.
45 Two parts of the course pursued by his Honour warrant brief attention, namely:
(i) the conclusion that the inadequacy in the reasons did not vitiate the decision itself and that that deficiency could be addressed by allowing the Tribunal now to provide reasons; and
(ii) reliance upon the ability of the Tribunal to invoke s 43AA of the AAT Act to provide reasons and, potentially, to reach a different decision to that already published.
46 As to the former matter, his Honour referred to the decision of Brennan J in Repatriation Commission v O'Brien (1985) 155 CLR 422 and to the subsequent decision of the Full Court in Dornan v Riordan (1990) 24 FCR 564.
47 In O'Brien,a decision of the Full Court was affirmed by a majority decision of the High Court. Justice Brennan dissented. However, his Honour discussed whether a failure to expose a satisfactory process of reasoning warranted an inference being drawn that the Tribunal had failed to exercise its powers in accordance with law and an order that its decision be set aside. It was in that context that Brennan J made the following observations at 445 as to whether a failure to provide reasons does 'invalidate [a] decision or warrant its being set aside':
It is not clear to me that the A.A.T. did fail to expose its reasons for rejecting Mr. O'Brien's claim but, in any event, a failure by a tribunal adequately to fulfil its statutory obligation to state the reasons for making an administrative decision does not, without more, invalidate the decision or warrant its being set aside by a court of competent jurisdiction. If a failure to give adequate reasons for making an administrative decision warrants an inference that the tribunal has failed in some respect to exercise its powers according to law (as, for example, by taking account of irrelevant considerations or by failing to consider material issues or facts), the court may act upon the inference and set the decision aside. In such a case, the exercise of the statutory power to make a decision is held invalid not because of a failure to state the reasons for making the decision, but because of a failure to make the decision according to law: … An obligation to give oral or written reasons for a decision is cast on the A.A.T. by s. 43(2) of the A.A.T. Act, but the remedy for a failure to fulfil that obligation adequately is a mandatory order by the court to do so. An A.A.T. decision, if it is made in accordance with the statutory provisions that govern the exercise of its power, is not invalidated by a mere failure to expose fully the reasons for making it.
In Dornan at 573, the Full Court referred to the observations of Brennan J and concluded that:
… [T]he law appears to us to be that a substantial failure to state reasons for a decision, in the circumstance that a statement of reasons is a requirement of the exercise under the statute of the decision-making power, constitutes an error of law.
Their Honours then considered the consequence of a failure to provide reasons:
In our opinion, there was in the present case a substantial breach of the Tribunal's duty to state the reasons for its determination.
Certainly the trial judge had a discretion as to the order he should make. …
In the present case, however, the reasons are so deficient that it is, in our opinion, impossible to ascertain whether there was any other error in the decision-making process.
The decision was set aside.
48 Subsequently, in Comcare Australia v Lees (1997) 151 ALR 647 at 659, Finkelstein J expressed his concurrence with the correctness of the judgment of Brennan J in O'Brien as to the consequences of the failure by the Tribunal to provide reasons for its decisions. However, his Honour concluded that 'as the Full Court [in Dornan] has reached a different conclusion I am bound to follow it'.
49 A failure to state reasons for a decision - at least in those circumstances where a statement of reasons is a requirement of the exercise of the decision-making process - constitutes an error of law: Preston v Secretary, Department of Family and Community Services (2004) 39 AAR 177 at [21] per Stone J; Hill v Repatriation Commission (2004) 207 ALR 470 at 474 per Mansfield J.
50 Common to the conclusions expressed in O'Brien by Brennan J and by the Full Court in Dornan remains the prospect of setting aside a decision of the Tribunal in circumstances where the inadequacy in the reasons permits an inference that the decision-making power has not been exercised in accordance with law, or where the deficiency is such that it is impossible to ascertain whether there was any other error in the decision-making process. In such circumstances it may be doubted whether there is such a stark difference in result as may have been assumed between the approach of Brennan J in O'Brien and that of the Full Court in Dornan. The discretion conferred by ss 44(4) and (5) of the AAT Act may well permit an order setting aside a decision under appeal.
51 The question outstanding is the very manner in which the discretion conferred by s 44 should be exercised. That is, whether the Tribunal decision, rather than its reasons, should have been set aside or should now be set aside and whether there should be remittal to the Tribunal, which now must necessarily be differently constituted.
52 Sections 44(4) and (5) of the AAT Actconfer ample power to make an order appropriate to the factual and legal issues presented to this Court on appeal. Those subsections provide:
(4) The Federal Court of Australia shall hear and determine the appeal and may make such order as it thinks appropriate by reason of its decision.
(5) Without limiting by implication the generality of subsection (4), the orders that may be made by the Federal Court of Australia on an appeal include an order affirming or setting aside the decision of the Tribunal and an order remitting the case to be heard and decided again, either with or without the hearing of further evidence, by the Tribunal in accordance with the directions of the Court.
53 A central contention advanced by CASA is that the deficiencies identified in the Tribunal's published reasons will either dictate a contrary conclusion being reached by the Tribunal or, at the very least, will in all likelihood lead to a different conclusion. The primary judge recognised this possibility but said that the Tribunal's decision and orders could be amended pursuant to s 43AA of the AAT Act. But, so CASA contends, there is no power conferred upon the Tribunal to make a different decision. It contends that, specifically, s 43AA(3)(b), which was relied on by the primary judge, does not confer such a power. Section 43AA is properly to be characterised as a provision 'in the nature of a slip rule': Hazim v Secretary, Department of Family and Community Services (2002) 116 FCR 533 at 541 per Gray J. See also: Telstra Corporation Ltd v Keen [2003] FCA 1440 at [13] per Sackville J.
54 Central sought to characterise the primary judge's reasoning as either obiter or 'speculative'. Central sought thereby to avoid a conclusion that any error in his Honour's reliance upon s 43AA(3)(b) was productive of appellable error and supported a conclusion that the appeal should simply be dismissed. Neither characterisation is correct. His Honour clearly contemplated that his order requiring the Tribunal to provide proper reasons may lead to a different decision and that there was no impediment to the decision being appropriately varied.
55 Notwithstanding the divergence in authority, a failure to comply with s 43(2) of the AAT Act should not inevitably lead to an order pursuant to s 44(5) that the Tribunal's decision should be set aside in its entirety or, alternatively, lead to the reasons alone being set aside and an order being made for reasons to be provided. The appropriate order to be made pursuant to s 44 will depend upon the facts and circumstances of each individual case and the exercise of the discretion thereby conferred.
56 The inadequacy in the reasons provided by the Tribunal in the present proceeding, and the fact that there was at least the prospect of a different decision being reached on the facts found by the Tribunal, could well have justified a conclusion that the decision should have been set aside. Indeed, given his Honour's recognition that a different decision may well have followed from such findings, the setting aside of the decision may well have been inescapable. This, in turn, is a factor in the exercise of the discretion conferred by s 44 of the AAT Act not to set aside the decision.
57 The primary judge was of the view that the inadequacy in the reasons provided could be addressed by s 43AA. In that regard, his Honour erred. Section 43AA does not confer the amplitude of power assumed by his Honour. Even had the original Tribunal member remained available to provide reasons, s 43AA does not confer the power to rectify the deficiencies in the reasons identified by the primary judge.
58 Section 43AA(1) of the AAT Act provides:
If, after the making of a decision by the Tribunal, the Tribunal is satisfied that there is an obvious error in the text of the decision or in a written statement of reasons for the decision, the Tribunal may direct the Registrar to alter the text of the decision or statement in accordance with the directions of the Tribunal.
Section 43AA does not confer power to revisit a decision once made, save in the limited circumstances expressly stated (Comcare v Moon (2003) 75 ALD 160, Iacono v Tax Agents' Board of Victoria (2006) 91 ALD 350 at [9] per Finn J, Collins v Military Rehabilitation and Compensation Commission (2005) 147 FCR 570 at [30] per Jacobson J). In Moon at [64]-[65] Mansfield J concluded that s 43AA conferred no power upon the Tribunal to revisit an order it had made as to costs:
[64] In my judgment, it is significant that s 43(5A) of the AAT Act provides that, subject to subs (5B), the decision of the Tribunal comes into operation upon the giving of the decision. Section 43(5B) does not apply to the present circumstances. It is also significant, in my judgment, that s 42A empowers the Tribunal to reinstate proceedings which it has dismissed, but only in limited circumstances. They do not apply in this matter. I note s 42A(9) provides:
If it considers it appropriate to do so, the Tribunal may reinstate the application and give such directions as appear to it to be appropriate in the circumstances.
But that subsection serves s 42A(8) also dealing with the dismissal of an application.
[65] The AAT Act, therefore, perfects the Tribunal's orders upon their being pronounced. There is power to correct obvious errors in the text of a decision or the reasons under s 43AA, but not to reverse or vary the decision. It could not be said that the Tribunal, having formally said it set aside the decision under review could then revisit the decision. Matters of expression, or inconsistency or error in calculation, could be corrected under s 43AA, but not the decision itself. If that be so, I do not see how the costs order element of the tribunal's reasons and orders does not have a similar status. Without more, it took effect when made and could be enforced. The Tribunal had given its decision orally, and thereafter its role at least to the extent its decision addressed and resolved matters specifically in issue was spent: see X v Minister for Immigration and Multicultural Affairs (2001) 116 FCR 319 at 326 [23]; 67 ALD 355 at 361 per Gray J.
59 Section 43AA does not confer a power to provide the very statement of reasons which should previously have been provided. If there be a failure to provide reasons which comply with s 43(2), that failure cannot be properly characterised as 'an obvious error in … a written statement of reasons'. There may appear to be an 'error' in the reasons which have been provided but the real complaint is that there has been no proper 'written statement of reasons'. Even on its terms, s 43AA has no application.
60 Section 43AA(1) of the AAT Act is a provision which, as its terms make clear, is directed to the correction of 'an obvious error in the text of the decision or in a written statement of reasons…'. Even in the absence of such available inferences as readily emerge from the examples of 'obvious errors' set forth in s 43AA(3), s 43AA(1) cannot be construed as conferring any power to alter or vary the actual decision itself.
61 The primary judge's conclusion that s 43AA(3)(b) of the AAT Act conferred power upon the Tribunal to vary its decision should it emerge that 'its new reasons are inconsistent with its current decision' was, with respect, an error. Section 43AA confers no such power. That error went to the exercise of his Honour's discretion in making the order setting aside the reasons for decision of the Tribunal, but not the decision, and remitting the proceeding such that reasons could now be provided. Nor was his Honour correct when he concluded that 's 43AA(3)(b) allows the Tribunal to correct its decision to ensure consistency with its reasons'.
62 Where it has been concluded that reasons as provided do not comply with s 43(2), s 43AA is not the source of power to rectify that inadequacy by providing reasons which do support the decision previously reached. Even if the inadequacy in reasons previously provided may be characterised as 'obvious', a conclusion which itself may well be doubted, it would be a curious construction of s 43AA(1) to conclude that that provision empowered a direction to be given to the Registrar to 'alter the … statement in accordance with the directions of the Tribunal' by the incorporation of new reasons either in addition to or in substitution for those previously provided. Even if the new or supplementary reasons could sit comfortably with those previously provided, it may well be doubted whether a direction to incorporate such reasons can truly be characterised as a mere 'alteration' of those previously provided.
