Ground 1 - The remittal
23 The primary judge accepted that ground 1 raised a question of law, namely, the consideration of the meaning and effect of the orders made by Branson J setting aside the First Tribunal Decision and remitting the matter to the Tribunal to be dealt with according to law.
24 His Honour noted that the submission made by Mr Kaluza was that the remittal order was unqualified and in the absence of any express limitation, it was for the Tribunal hearing the matter to determine all questions of facts and law relevant to the application.
25 Mr Kaluza submitted before the primary judge, and his Honour noted, the observation made by the Full Court in Peacock v Repatriation Commission (2007) 161 FCR 256 (at [18]) that it would be 'a rare case' in which a limitation in the remittal would be inferred from the reasons for judgment given by the remitting judge 'when the terms of the remittal are unqualified':
We accept that Dowsett J might have limited the matter he was remitting for further consideration, but we think that it will be a rare case in which such a limitation can be inferred from reasons for judgment when the terms of the remittal itself are unqualified. ....
26 The Commission argued and the primary judge accepted that this observation by the Full Court was not intended to place a restriction on the ability of the Tribunal to determine the nature of the hearing on the remittal having regard to the terms of the order and the circumstances of the case. His Honour followed Repatriation Commission v Nation (1995) 57 FCR 25 per Beaumont J (at [33]) (with whom Black CJ and Jenkinson J agreed), Morales v Minister for Immigration and Multicultural Affairs (1998) 82 FCR 374 (at 387) as well as Walker Corporation Pty Ltd v Sydney Harbour Foreshore Authority (2009) 168 LGERA 1 per Basten JA (at [37]) (with whom Beazley JA and Young JA agreed).
27 Also accepted by his Honour was the Commission's submission that there was sufficient ambiguity in the terms of the order under consideration to warrant consideration of the reasons and context giving rise to the orders. In that regard, the primary judge referred to the statutory conferral of power under s 44(1) of the AAT Act entitling, once a jurisdictional prerequisite was satisfied, the Court to make such orders as it thinks fit including an order 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: see s 44(4) and s 44(5) of the AAT Act. Subsection (6) provides that the Tribunal need not be constituted by the tribunal members who made the decision to which the appeal related. The primary judge took the view (at [75]) that the exercise of power by Branson J to set aside the decision of the Tribunal and remit the 'matter' was expressly predicated upon the reasons given by her Honour for answering the second question favourably to Mr Kaluza. It followed that the 'matter' remitted was only the question of whether the second leg of the journey from Vietnam, via Butterworth in Malaysia, to Pearce in Western Australia was part of Mr Kaluza's 'operational service'. The only error of law committed by the Tribunal as identified by her Honour was that it failed to consider whether Mr Kaluza's allotment for duty on the return leg from Butterworth to Pearce was operational service rendered by Mr Kaluza. The primary judge noted the observation by her Honour (at [25]) that neither party identified a reason why the Tribunal should be differently constituted or for further evidence to be adduced to be consistent with the view as to the scope of the remittal.
28 The Commission argues now, as before the primary judge, that were this not so, the effect would be that the entire case including the question on which Mr Kaluza had been unsuccessful in the First Tribunal Decision and on appeal would be remitted to the Tribunal. In this regard, the primary judge took the view that the distinction in Peacock was directed principally to the question of whether a new question could be raised at the rehearing. His Honour considered that to be quite a different position from the present case where the question had been raised and answered adversely both at the initial hearing in the Tribunal and on the appeal to the Court. Rather, the position was analogous to that which occurred in Nation.
29 On appeal, the Commission has maintained its position and adopts the approach taken by the primary judge. In particular, the Commission submits that the approach taken by the primary judge would not lead to 'increased uncertainty in litigation' as contended for by Mr Kaluza. Such a proposition, it says, is not supported by authority and the primary judge did not suggest that one consider the reasons in every case in order to construe the scope of the orders made. Nevertheless, it was clear on authority that where there was uncertainty as to the scope of an order, it was proper for the Court to consider the nature and context of the relevant dispute.
30 The Commission also relies on the fact that at no point during the appeal had Mr Kaluza foreshadowed that he wished the whole of the claim to be reconsidered. The Commission stresses that there is nothing in her Honour's reasons which could support a finding that all matters needed to be reconsidered. It would be wrong to construe the order to mean that having success on a limited point would be success on all points. The Commission argued that confining the remittal, as was the approach taken by the Tribunal and the primary judge, promoted certainty for the parties and the Tribunal as to the scope of any further hearing.
31 The Commission also submits that s 44(4) and s 44(5) of the AAT Act would suggest that the evidence already taken in an earlier hearing is to continue to be evidence before the Tribunal.
32 As against those submissions, the history of this matter appears to be that no submissions had been made by any party to her Honour to the effect that any remittal should be limited. The width of the Court's power under s 44(4) of the AAT Act makes it clear that were it the intention to expressly impose a limitation on the remittal, it would be open to the Court to do so.
33 Section 44(5) speaks in terms of affirming or setting aside the decision and remitting the 'case' rather than remitting the 'matter'. Although no technical distinction arises, in our view, there is no reason to consider that there was any limit on the remittal as the Commission contends. The effect was simply to remit the case to the Tribunal to be heard and decided again without any directions being imposed limiting how the Tribunal was to proceed. Although different views were taken in Nation and Morales when a 'matter' was remitted, those two decisions preceded Minister for Immigration and Multicultural Affairs v Wang (2003) 215 CLR 518. Peacock in contrast not only post-dated Wang but took into account the reasoning in Wang. That reasoning is pertinent to this appeal.
34 In Wang the High Court allowed an appeal from the decision of the Full Court of this Court which had directed that a matter be remitted to the tribunal 'as previously constituted'. Gleeson CJ held (at [7] and [16]) that orders setting aside a decision and remitting the matter to be determined according to law meant that all questions of fact and law relevant to the claim before the tribunal (in that case, the Refugee Review Tribunal) had to be determined again. McHugh J noted (at [45]) that the tribunal was not bound to make the same findings that it had made on the first occasion and Gummow and Hayne JJ (at [67]) held that the Court's orders taken as a whole provided for the tribunal to begin its statutory task again.
35 When the Full Court came to consider this situation again in Peacock in 2007, the question for consideration arose from a single judge having upheld an appeal on the basis that the Tribunal had erred in applying the criteria set out in s 24(1)(c) of the Veterans' Act. That was an issue which had previously been conceded by the Commission. The Full Court held that the Tribunal had not erred in doing so. After considering Nation, Morales and Wang the Full Court departed from the approach taken in Nation and Morales concluding (at [6]) that once the prior decision of the Tribunal was set aside, in the absence of some express limitation, it was then for the Tribunal hearing the matter to determine all questions of fact and law relevant to the claim. As appeals are limited to questions of law it was unsurprising that the issues discussed in the appeal were limited but it did not follow that what was remitted was confined to the issues relating to that question of law. As the primary judge noted, the Full Court commented (at [18]) that it would be a rare case in which a limitation to a remittal would be inferred from reasons for judgment when the terms of the remittal were unqualified.
36 In Peacock (at [19]) the Full Court said:
The respondent referred us to Morales v Minister for Immigration and Multicultural Affairs (1998) 82 FCR 374, particularly at 63 [scil 387-388] and Repatriation Commission v Yates (1997) 46 ALD 487 at 492-494, in which orders remitting "the matter" were held to require that the whole matter must be heard and decided again. The applicant relied on Repatriation Commission v Nation (1995) 57 FCR 25. In that case the Full Federal Court held that a remittal of "the matter" was sufficiently ambiguous to permit resort to surrounding circumstances. The Court held that the terms of the reasons made it clear that the remittal was restricted. However, in that case it had been accepted since 1983 that the veteran's sinusitis condition had been war-caused. The only matter decided by the Commission to which the appeal and remittal related was whether another condition, anxiety neurosis, was also war-caused. Accordingly, the remittal did not permit the veteran's entitlement arising from his sinusitis to be reconsidered. This case is quite different. It is argued here that the remittal excludes matter that was before the Commission when it made its decision under review.
37 Ordinarily orders made by a court will be taken at their face value rather than being construed in context having regard to their purpose and object. It would be, as the Full Court noted in Peacock, a rare case where it was otherwise. There is nothing 'rare' about this remittal. It is and was open to the Court partially to remit a matter but in this case that was not done. Her Honour was not asked partially to remit the case. Cases on judicial review frequently refer to two or more claims. It is common for a large number of issues to be agitated on judicial review but it may only be one of those in which there is success and remittal. It cannot be said that a decision-maker exercising executive power is confined to considering only those issues in respect of which a point of law was made out. This is particularly so in the context of s 44 of the AAT Act which is restricted to appeal on an error of law.
38 The Commission argued, and the primary judge accepted (at [72]), that the orders of the Tribunal were ambiguous in the sense described in the reasoning of Beaumont J in Nation. It seems to us that this approach has been displaced by the reasoning in Wang which was followed in Peacock. In light of the statements in Wang, in our view, unless there is some qualification in the remittal order, there is nothing ambiguous about the order. The entire case is remitted. See also the consideration of a similar issue in R v Carroll (2010) 77 NSWLR 45 at [29]-[30].
39 In relation to the Tribunal three further and related considerations are relevant.
40 First, the Tribunal stands in the shoes of the primary decision-maker and by s 43(1) of the AAT Act, for the purpose of reviewing a decision, may exercise all the powers and discretions that are conferred by any relevant enactment on the person who made the decision. In our view construing the scope of a remittal as limited would tend to run counter to the Tribunal's function.
41 Second, it would often be impossible or undesirable for the Court to seek to anticipate how it may be that one factual issue might interrelate with another even where the legal issues are separate. The Tribunal acts on the material before it without being limited in the same way in which the Court is generally limited on judicial review to the material before the primary decision-maker. Depending on the subject-matter and on the length of time between the date of the Tribunal's decision and the exhaustion of the s 44 appeal process, the material before the earlier Tribunal may no longer be up to date in the Minister for Aboriginal Affairs v Peko-Wallsend Ltd (1986) 162 CLR 24 sense. It may be legally embarrassing to the Tribunal to be required to approach the fact finding task in this limited way and therefore be a reason not to construe a general remitter as limited by and to a specific question of law where more than one such question was argued before the court.
42 Third, the Peacock approach avoids potential anomalies where a question of law and the facts associated with it has not been the subject of appeal, cross-appeal or a notice of contention.
43 Legal policy also favours simplicity and certainty: see, in another context BP Australia Ltd v Brown (2003) 58 NSWLR 322 at [115]-[116].
44 This does not mean that there is an obligation on the Tribunal to rehear all the same evidence. It is for the Tribunal rehearing the matter to determine all questions of fact and law relevant to the claim. By considering that it was bound to only consider the 1969 claim (rather than it being open to it to entertain an application to adduce new evidence on the 1968 claim), the Tribunal did not consider the entire remittal and deprived itself of the obligation to consider the 1968 flight claim.
45 Although the Commission suggests that there was a limited remittal by reason of her Honour's decision not to make any directions for a different constitution of the Tribunal or for evidence to be adduced, we regard these factors as being neutral in character. They are capable of amounting to a notation that, in effect, her Honour had directed her mind to whether or not such orders had been sought. Her Honour did not have to make any such orders as none had been sought.
46 Given that the First Tribunal Decision was affected by legal error, it is the entire determination comprising the various claims within it that was set aside, not the legal error giving rise to an erroneous conclusion as to one of the claims.
47 It is contended for the Commission that the Tribunal simply exercised its own discretion as to how to deal with the rehearing. Thus the Commission contends that the better approach for Mr Kaluza would have been to accept the loss on the first leg of the appeal and to have made an application to reopen on the basis that there was new evidence. That might have led the Tribunal to take a different consideration into account. However, it seems clear to us from the language used in its considered reasons, that the Tribunal regarded itself as being bound not to embark further on enquiry in relation to the 1968 claim. The Tribunal was not so bound as a result of the order remitting the matter but it was open to the Tribunal to, for example, entertain, consider and reject the application to adduce fresh evidence on the 1968 claim. The language of its reasons however, consistent with the Commission's submissions advanced to it was in terms of being bound to consider only the 1969 claim. At [29]-[31] of the Second Tribunal Decision it was made clear that it considered itself to be bound:
29. By contrast it was clear to us that Justice Branson qualified her remittal. We accordingly preferred the submissions of the Respondent regarding the limited remittal in Mr Kaluza 's case, and are satisfied that what we must do is limited to the acceptance of the Applicant's flight home from Vietnam on 22 - 26 February 1969, in full, as operational service. In doing so, we rely on paragraph 38 of Walker where their Honours stated as follows:
Furthermore, in considering both the intended scope of a remitter and the appropriate scope of the hearing following remitter, a material consideration will often be the nature of the matter in dispute. Thus, a different approach may be taken in respect of a claim which is to be determined in accordance with the facts as they exist at the time of the remitted decision, as compared with a claim which involved the assessment of facts at a fixed time in the past. The present case falls into the latter category.
30. We accept the facts relating to Mr Kaluza and his evidence as they existed at the time of the Tribunal's first decision, and remitted decision. His evidence regarding the stressors he experienced in 1969 cannot, in any case, be changed. We informed the parties that we would not require further evidence to be adduced, and are mindful that ultimately we must conduct proceedings as we see fit (section 33, Administrative Appeals Tribunal Act 1975). We must therefore consider the evidence surrounding the operational service flights in which Mr Kaluza participated in February 1969, and the stressors he claims as causing the conditions he suffers to be war-caused.
31. Remittals are different in each case, and must take into account the circumstances of the case. It is true in many circumstances the whole case is remitted. However in this case, the first leg of the appeal was not upheld, and Justice Branson remitted only the second, with a proviso that the Tribunal did not need to be reconstituted, and that no further evidence was necessary. We are satisfied that Justice Branson remitted the matter in a limited way, and have dealt with it accordingly. (emphasis added)
48 For those reasons, we accept Mr Kaluza's arguments. What was remitted was the entire case. It is not a question of whether Mr Kaluza should have been permitted to 'reopen his entire claim' as advanced by the Commission. It is rather a question of identifying precisely what was remitted. As the First Tribunal Decision had been set aside, what was remitted was the entire application to the Tribunal. The error on the part of the Tribunal was to consider that it was precluded from considering the grounds which were not upheld on the First Appeal.
