the procedural fairness argument
51 The applicant submitted that the AAT had denied him procedural fairness in rejecting his claim that he required attendant care services to assist him in the event of drop attacks. Mr Daley put the procedural fairness argument in a number of different ways. In substance, his contention was that the respondent had not identified the availability of an alarm system as an issue until Dr Henke gave evidence about it on the third day of the hearing. The applicant had accordingly been denied the opportunity to elicit evidence from his own doctors (Drs Do and Tam) and the respondent's counsel had failed to ask questions of those doctors about the alarm system. Since the significance of the alarm system had never been an issue in the proceedings, it was a denial of procedural fairness for the AAT to reject the applicant's claim on the basis that the system could serve his needs. It was also said to be a breach of the rule in Browne v Dunn (1893) 6 R 67, for the respondent's counsel not to have put the alarm system option to the applicant's doctors.
52 Mr Daley was, in my view, correct in his contention that Dr Henke's evidence as to the alarm system played a significant part in the AAT's conclusion on this issue. As Mr Daley pointed out, the AAT (at [223]) found "considerable merit" in Dr Henke's suggestion that it would be preferable to provide an around the clock personal alarm system, especially one that activates automatically in the event of a precipitate fall. Later in the reasons, when addressing the applicant's submissions, the AAT returned (at [245]-[246]) to the topic of the alarm system:
"Mr Daley addressed Dr Henke's suggestion that an alarm system would suffice to provide the assistance required by [the applicant]. He submitted that the suggestion should be disregarded for several reasons. It emerged without warning as a suggestion at the close of the respondent's case. It had never been part of any offer of assistance by the respondent. It had never been put to [the applicant] as an option. It has not been recommended by anyone following an on-site assessment of [the applicant's] requirements.
The tribunal considers that the alarm option came as something of a surprise to the respondent, as it did to the applicant's representatives, when Dr Henke suggested it. The tribunal saw Dr Henke's evidence as well considered and thoughtful when he suggested that an alarm system might best assist the applicant with his genuine disability. The tribunal considers that the respondent should give serious consideration to offering such a facility to [the applicant] in accordance with s 39(1)(e) of the 1988 Act."
These passages suggest that the AAT gave some weight to the availability of the alarm system in reaching its conclusion that the applicant did not require "attendant care services" to assist him if he suffered drop attacks.
53 In order to determine whether the AAT denied the applicant procedural fairness, it is necessary to trace briefly the course of the evidence and the submissions in the AAT in relation to the personal alarm issue. As Mr Daley submitted, the respondent's statement of facts issues and contentions did not allude to the argument that an alarm system would meet the applicant's needs arising from the drop attacks. On the other hand, as Mr Elliott, who appeared for the respondent before the AAT, as in this Court, pointed out on behalf of the respondent, the applicant's own statement did not foreshadow reliance on "drop attacks", as distinct from "episodes of dizziness and imbalance leading to falls". The applicant's reliance on drop attacks only became evident later, through medical reports served in support of his case.
54 Mr Daley was correct to point out that no mention was made of alarm systems until the third day of the hearing. In response to a general question asked in examination in chief by Mr Elliott, Dr Henke referred to the role that can be played by an alarm system in protecting people prone to loss of consciousness:
"[Q] Do you believe that the risk from drop attacks is such that he needs a constant carer to be present?---[A] The difficulty here is that one sees that the carer is not going to be able to stop the drop attacks…. So if we're looking at the risk of injury arising from the attack, having a carer there in a sense doesn't really change the probability of potential injury. If we accept that these are short-term attacks, a loss of consciousness lasting a minute or two, then clearly the concern then would be whether he could seek help if he was injured in such a fall. Obviously formally one can handle that by provision of some form of alarm system if people fall. If we had a person in hospital comes in with epilepsy who has it frequently, the usual thing is to recommend installation of something like what is called: Vital Call, which is an alarm system the person carries on them which if they do have an injury they can press a button for."
There is no suggestion that counsel for the respondent had deliberately withheld this material when cross-examining the applicant or his medical witnesses. Indeed, the AAT found otherwise.
55 Mr Daley did not object at the time to the AAT receiving Dr Henke's evidence. Nor did he seek to cross-examine Dr Henke on the issue or to defer his cross-examination until further instructions could be obtained. In re-examination, Dr Henke explained that alarm devices could be activated by sudden movement and that the cost of monitoring them was about $1 per day. Again, no objection was taken to this evidence.
56 Further medical reports were tendered later on 7 June 2001. Not surprisingly, none addressed the significance of personal alarms for the applicant's case. At the conclusion of the hearing on that day, the matter was adjourned until 13 June 2001, to enable final submissions to be made.
57 At the resumed hearing, Mr Daley made oral submissions on behalf of the applicant. Towards the end of his submissions, he turned to what he described as "the last of the respondent's defences", as follows:
"That is the alarm. That was a rabbit pulled out of the hat at about 12.30 on day 3, it has come out of left field. It wasn't something that was mentioned at any time in the decision making process. It wasn't something that reached Dr Henke's two reports. It wasn't something that was put to the applicant's doctors so the Tribunal has not been assisted by an alternate view of what benefit these alarms might be or what their practicalities might be in Mr Haberfield's specific case.
We just don't know. My respectful submission is that in so far as that issue has been raised, it should be disregarded for a number of reasons. Firstly, that it has never formed any part of the respondent's case. It has literally as anything can come out of left field at the end of the case. It has never been raised by the respondent at any time in terms of something that could be put in place by the respondent to mitigate its obligations to otherwise pay the applicant compensation. There's been no offer to put it in place, even as late as today I do not understand the respondent to say well, if you give up 3 hours a day of your care claim, we will install an alarm system.
It has just never been put to the applicant that that was an option and it still has not. We also don't know how valuable or how practicable it is likely to be in circumstances of Mr Haberfield's case because no one has ever gone out to assess him. Dr Henke has given evidence from the general perspective that they can be useful but I think he even conceded that in the course of his evidence that one really needs to get out there and see whether the home is set up right for it and whether the other factors in terms of practicality can be satisfied and there's just no evidence that in this particular case those things have or could be satisfied.
…
If the Tribunal was of the view that an alarm system was a meritorious option in this case, what I would respectfully submit is that the appropriate approach would be for the Tribunal to reinstate the applicant's case allowance, provide a recommendation that the respondent could try one of these alarm systems to see whether or not in Mr Haberfield's case they are useful and indicate a view in the Tribunal's mind that if it were successfully implemented, this could reduce the care by X number of hours per week."
As has been seen, the AAT rejected the submission that Dr Henke's evidence should be disregarded.
58 The AAT is not bound by the rules of evidence: AAT Act, s 33(1)(c). It is, however, obliged to adopt "fair procedures which are appropriate and adapted to the circumstances of the particular case": Kioa v West (1985) 159 CLR 550, at 585, per Mason J; Dolan v Australian and Overseas Telecommunications Corporation (1993) 42 FCR 206, at 207, per Spender J; Lodkowski v Comcare (1998) 53 ALD 371, at 386, per Goldberg J. The application of the rule in Browne v Dunn has been treated as an aspect of procedural fairness and, if breached, capable of vitiating a decision of the AAT: Hoskins v Repatriation Commission (1991) 32 FCR 443, at 446, per Pincus J; Dolan v AOTC, at 208, per Spender J. The rule in Browne v Dunn was formulated by Hunt J in Allied Pastoral Holdings Pty Ltd v Commissioner of Taxation [1983] 1 NSWLR 1, at 16, as follows:
"It has in my experience always been a rule of professional practice that, unless notice has already clearly been given of the cross-examiner's intention to rely upon such matters, it is necessary to put to an opponent's witness in cross-examination the nature of the case upon which it is proposed to rely in contradiction of his evidence, particularly where that case relies upon inferences to be drawn from other evidence in the proceedings. Such a rule of practice is necessary both to give the witness the opportunity to deal with that other evidence, or the inferences to be drawn from it, and to allow the other party the opportunity to call evidence either to corroborate that explanation or to contradict the inference sought to be drawn."
59 The application of the rule in Browne v Dunn as an aspect of procedural fairness must take account of the statutory functions of the AAT. The task of the AAT is not necessarily limited by the issues identified by the parties. As was said by Brennan J in Bushell v Repatriation Commission (1992) 175 CLR 408, at 425, in substance the AAT's review of the primary decision is inquisitorial in character, with the AAT under a duty to arrive at the correct or preferable decision on the material before it. Subject to the rules of procedural fairness, the AAT is entitled to inform itself on any matters relevant to the pleadings in such manner as it thinks appropriate: s 33(1)(c).
60 It is true that the alarm system issue was not flagged in the statements of facts, issues and contentions filed in the AAT. But Dr Henke having answered the question in the manner he did, without objection, there was material before the AAT that was relevant to the question of whether the applicant had a need for the services of a carer on a daily basis to assist him in the event of drop attacks. Of course, the mere fact that Dr Henke's opinion was admitted into evidence without objection does not necessarily establish that it was procedurally fair for the AAT to take it into account. If, for example, the applicant had no realistic opportunity to consult with his own doctors or medical experts, or was denied the opportunity to adduce material rebutting Dr Henke's opinion, arguably it might have been unfair to allow the evidence "to come out of left field" in the manner it did. But this is not what happened.
61 Once Dr Henke's opinion on the use of an alarm was before the AAT, it was open to the applicant's counsel to apply to recall Dr Do and Dr Tam or, indeed, to call other evidence addressing this issue. In fact no such application was made. There was a gap of six days between Dr Henke's oral evidence and the date fixed for the making of written submissions. There was no evidence in this Court and no suggestion made on behalf of the applicant that that period was insufficient to enable his advisers to consult with the treating doctors or the medical experts. Nor can it be said that the applicant's counsel failed to appreciate the significance of the evidence. In fact, he strenuously endeavoured to persuade the AAT to disregard it or give it little weight, precisely because (so I infer from the transcript) he understood its potential importance.
62 In Karidis v General Motors-Holden Pty Ltd [1971] SASR 422, Bray CJ (with whom Sangster AJ agreed) observed (at 425) that, where Browne v Dunn is invoked, it is necessary to examine the rationale underlying the rule. Karidis involved the tender of a film showing the appellant's activities on two occasions, without the appellant having been cross-examined on the contents of the film. Bray CJ said this (at 425-426):
"It seems to me that under contemporary practice, when the calling of witnesses in rebuttal is very common, the occasions for the intervention of courts of appeal on this ground may be less frequent. The reason for the principle is obviously that the witness ought to have the opportunity to give what explanation he can of the matter in question and that he should not be disbelieved, nor should adverse inferences be drawn against him, because of other evidence relating to the topic on which he has been unable to comment.
In the present case no application was made to call the appellant or Dr Chick in rebuttal after the films had been proved by Mrs Lock. If such an application had been made and refused, or if for any reason it was impracticable for either witness to be called in rebuttal, the matter would stand differently. But there is no reason to suppose that such an application would not have been granted or that the witnesses were not available."
63 The present case has some similarities to Karidis although, if anything, there is less reason to apply the rule in Browne v Dunn. It was common ground that the respondent's counsel had not made a deliberate forensic decision to avoid questioning the applicant's witnesses about alarm systems; the issue had simply not arisen until Dr Henke mentioned it. Moreover, Dr Henke's evidence on the specific topic of the alarm system did not directly contradict the evidence of the applicant's witness or, of itself, cast any doubt on their credibility. The evidence identified a particular factor that lent weight to Dr Henke's opinion that the applicant did not require the services of a carer by reason of his susceptibility to drop attacks. It was open to the applicant's counsel to apply to adduce further evidence to address the issue raised by Dr Henke, but he did not do so. There is nothing to suggest that if he had applied to recall witnesses or to have the proceedings adjourned that the AAT would have declined the application.
64 In my view, there was no procedural unfairness to the applicant in the AAT taking into account the evidence given by Dr Henke. Counsel could have invited the AAT to receive further evidence on the significance of alarm systems, but elected not to do so. (In making this observation I intend no criticism of counsel. As Bray CJ observed in Karidis, at 426, advocacy involves a continual series of difficult choices and appellate courts should be slow to comment on a particular choice.) The issue was plainly identified and was the subject of submissions to the AAT. It follows that the applicant has not made out that the AAT's decision was affected by a breach of the principles of procedural fairness.
65 Mr Daley submitted, in the alternative, that by giving weight to Dr Henke's evidence concerning the alarm system, the AAT had taken an irrelevant consideration into account. The evidence was, however, plainly relevant to the factual questions the AAT had to determine. The weight to be given to the evidence was a matter for the AAT.
