the scope of the remittal
4 As the Reasons explain, Ms Negri's appeal succeeded. Accordingly, an order needs to be made remitting Ms Negri's case to the Tribunal for redetermination. As I said in O'Loughlin v Linfox Australia Pty Ltd (2015) 235 FCR 164 at [68] (which I repeated at [112] of the Reasons):
[68] … A remittal may be on a confined basis, or at large: Repatriation Commission v Nation (1995) 57 FCR 25 (Beaumont J, with whom Black CJ and Jenkinson J agreed); Stateships v Lawson (2009) 107 ALD 42 at 53 (Gilmour J). Where no condition is imposed on remittal, the whole of the case is remitted without limitation as to the presentation of further evidence or as to the scope of the matter to be dealt with: Rigoli v Federal Commissioner of Taxation (2014) 96 ATR 19 at [34] (Edmonds, Jessup and McKerracher JJ). An unqualified remittal, even for a matter to be determined according to law, would require the whole of the matter to be heard and decided again, and all questions of law and fact relevant to the claim to be considered and determined: Rigoli at [34], citing Peacock v Repatriation Commission (2007) 161 FCR 256 (Downes, Lander and Buchanan JJ).
5 Ms Negri submitted that the remittal should be unconfined. The Secretary took a different view. The Secretary submitted that the Court should remit the case to the Tribunal:
… limited to reconsideration as to the following matters, without hearing further evidence, or without further evidence unless proper cause be shown:
a. That the Tribunal further consider the submission made on behalf the Applicant in respect of the evidence of Dr Kader and having regard to the reasons of the Court determine whether the Applicant's condition of depression had been diagnosed as required by the Introduction to Table 5 of the Tables in respect of the period 16 October 2012 to 15 January 2013 (paragraph 3 of the reasons of the Tribunal) (the relevant period).
b. If the Decision in respect of a. is "yes", the Tribunal decide whether the Applicant's condition of depression was a permanent, "fully diagnosed", "fully treated" and "fully stabilised" condition (as defined by the Tables) in the relevant period.
c. If the answer in respect of a. and b. is "yes", the Tribunal what was(if any), in the relevant period, the appropriate impairment rating under Table 5 arising from the Applicant's condition of depression.
d. Only in the event the Tribunal finds in favour of the Applicant in respect of the matters in a. to c. and finds that an impairment rating of at least 10 points should be assigned under Table 5 of the Tables, the Tribunal decide whether the Applicant satisfies the requirements of section 94(1)(c) of the Social Security Act 1991 (the Act) in the relevant period.
6 There are, I think, two significant issues in relation to which the parties are at odds. First, should the redetermination be made on the evidence before the Tribunal without further evidence? Second, should the redetermination be confined to Ms Negri's claim of depression under Table 5 of the Tables and, if it arises, to a consideration of whether Ms Negri satisfies the requirements of s 94(1)(c) of the SS Act?
7 As to the first question, I agree with the position for which the Secretary contends. As [2] of the Reasons records, Ms Negri's entitlement relates to an assessment period in late 2012 and early 2013. I presume that all of the evidence that each of the parties thought was necessary to be put before the Tribunal in relation to that assessment is already before the Tribunal. No updating is required. I am not aware of any reason for fresh evidence to be adduced. The AAT Act in ss 2A and 33 promotes the idea that reviews carried out by the Tribunal be dealt with economically. Whilst the need for economy does not trump the need for a fair review conducted according to law, there is nothing before me to suggest that such a result could not be achieved on the evidence already before the Tribunal. I take into account, however, that the unexpected sometimes happens and that inflexibility may hinder a fair result. Accordingly, I will order that the case be remitted for redetermination without further evidence unless proper cause be shown. That is, I will reserve to the Tribunal a capacity to admit fresh evidence if proper cause is shown.
8 The second question is more complicated. The Secretary's position is that the Court's order for remittal should reflect my finding of an error of law. As an error of law was only found in relation to ground 2 and the question of whether the Tribunal had properly determined Ms Negri's claim for depression under Table 5, the Secretary contended that it is only that aspect of Ms Negri's claim which should be redetermined, and not the claim made by Ms Negri in relation to fibromyalgia which, free of error, the Tribunal assessed as warranting 10 points under Table 1.
9 There is a difficulty with that submission. It is this. If, on the redetermination of the depression aspect of the claim, Ms Negri is assessed as having less than 20 points under Table 5, her rating under Table 1 in relation to fibromyalgia may have a bearing as to whether Ms Negri satisfies the 20 or more points requirement of s 94(1)(b). The Secretary's position is that the rating of 10 points under Table 1 previously assessed by the Tribunal on 26 February 2015 ("first Tribunal") in relation to fibromyalgia should remain undisturbed. Ms Negri, says that the difficulty with that is that, if, on the redetermination, Ms Negri is assessed as satisfying s 94(1)(b), for the purposes of s 94(1)(c), the reconstituted Tribunal ("second Tribunal") would have to assess the combined impact of Ms Negri's fibromyalgia and her mental health condition on her incapacity to work or participate in training so as to determine whether s 94(2)(aa), (a) and (b) are satisfied. That assessment, so Ms Negri contends, may give rise to inconsistent findings about the impact of Ms Negri's fibromyalgia as between the first and second Tribunals if the second Tribunal is unable to make its own findings as to all of those aspects of Ms Negri's claim which rely on fibromyalgia. The potential for inconsistency is perhaps greater than it might have otherwise been because the member that constituted the first Tribunal is no longer a member of the AAT. Consequently, a different member will necessarily constitute the second Tribunal.
10 If, by the scope of the remittal, the second Tribunal is required to adopt the ultimate finding of the first Tribunal in relation to Table 1, the first Tribunal will, in essence, be also adopting each of the findings made by the first Tribunal in relation to fibromyalgia. At the same time, in determining whether Ms Negri had a "continuing inability to work" as required by s 94(1)(c), the second Tribunal will be required to make its own findings in relation to fibromyalgia. Those findings may be inconsistent with the findings of the first Tribunal. It would be very undesirable for the second Tribunal's decision to be based upon an inconsistency of the kind I have identified. That potential for inconsistency, to my mind, is graver than the potential for an inconsistent result as to the appropriate rating under Table 1 as between the first and second Tribunals.
11 The Secretary contended in response that the possibility of inconsistent findings can be avoided. The Secretary says that the first Tribunal's findings, made when determining the Table 1 rating for Ms Negri, should be adopted by the second Tribunal for determining the impact, if any, of fibromyalgia on the question of whether or not Ms Negri has a "continuing inability to work".
12 The difficulty with that response is that it would likely substitute one potential problem for another. The first Tribunal did not consider and therefore did not make any findings specific to the issue of whether or not Ms Negri has a "continuing inability to work". If, on the redetermination, the second Tribunal gets to that issue, it will then arise for the first time. In my view, the second Tribunal will need to address that issue by reference to its own findings and not by adopting findings about Ms Negri's fibromyalgia made by the first Tribunal but in relation to the determination by the first Tribunal of a different issue, namely, what rating should be given under Table 1. As Ms Negri submitted, in striving to avoid inconsistent findings, the second Tribunal may fetter its own decision making and fall into error. In this respect, a limited remittal may well bring about diseconomy to the ultimate disposition of Ms Negri's claim. Confined remittals, as Gummow and Hayne JJ observed in Minister for Immigration and Multicultural Affairs v Wang (2003) 215 CLR 518 at [73]-[74], can cause difficulty.
13 In the circumstances, I do not propose to confine the remittal to the issues contended for by the Secretary. Should it become necessary for the second Tribunal to address an aspect of Ms Negri's claim that raises a consideration of Ms Negri's fibromyalgia, the Tribunal should make its own findings. As Ms Negri submitted, should that need arise, the fibromyalgia evidence will be revisited in any event and the practical benefit of limiting the referral will be marginal.
