His Honour dealt with the definition in s 40(2) of the 1988 Act, taking into account these considerations, at [92]:
"In my opinion, what is necessary is a full account of acts and omissions of the claimant and of persons acting on behalf of the claimant, in so far as those acts and omissions are relevant to the explanation for the delay. When one comes to the second sentence of s.40(2), the specific reference to 'a reasonable person in the position of the claimant' means, in my opinion, that the focus there is directed solely at the acts and omissions of the claimant himself or herself, and must be judged as against what would have been the actions and omissions of a reasonable person in the position of the claimant, that is having the relevant characteristics of the claimant, in this case a nine year old girl suffering brain damage."
48 The result of adopting a more restricted scope for the conduct to be addressed under the second limb, was to focus attention upon the relevant characteristics of the claimant. Foster AJA agreed with Hodgson JA that the focus of the second limb, referring to a reasonable person in the position of the claimant, required attention to the claimant's activities, knowledge and belief: at [125]-[127]. His Honour concluded that the objective element was, in that case "an absurdly artificial yardstick, namely the standard of a reasonable brain-damaged infant". His Honour concluded that the objective test in the second sentence could not operate (at [128]) but concluded:
"Having regard to the reasonable reliance of the family upon the solicitor's advice and the total incapacity of the opponent herself, I am satisfied that the explanation is satisfactory."
49 This approach supported that of Hodgson JA, in that it looked to the conduct of the claimant and, in the circumstances of the case, her family, but did not seek to assess the satisfactoriness of the solicitor's conduct. On the other hand, that support was weakened by the fact that his Honour expressly derived the test from the first sentence of the statutory provision and not the second. His reliance on the judgment of Studdert J in Guest v Southern (unrep, 22 September 1995), which dealt with an earlier legislative provision in significantly different form and which did not include reference to "a reasonable person in the position of the claimant", cast doubt on the basis of Foster AJA's approach to satisfactoriness.
50 A second matter, Manderson v Ellis (by his Tutor) (2002) 37 MVR 214 was heard before judgment was handed down in Diaz, but decided after Diaz. The case apparently involved the same solicitors and also a plaintiff with a disability including brain damage sufficient to prevent him giving instructions. Santow JA referred to Diaz, noting at [18] that the views of Foster AJA "generally" favoured the views of Hodgson JA. His Honour continued:
"But Foster AJA agrees with Hodgson JA that the second sentence in s40 (2) … focuses attention on the claimant, at least to the extent that his particular position in the whole of the factual situation is to be taken into account: [125]. But he would require, as would Giles JA, that the explanation also satisfy an objective standard of reasonableness applied to the claimant circumstanced as he was … . I would apply that double-barrelled test here, and focus on the explanation the claimant has, not his solicitor, but including under 'claimant' the person in charge of his affairs … ."
51 Davies AJA, in Manderson at [58]-[60] concluded that the solicitors for the claimant had been negligent, not only in failing to commence proceedings in time, but also in failing to provide a full and satisfactory explanation for the delay. Because the onus was on the defendant under the 1988 Act, it failed to establish that there was no full and satisfactory explanation. McClellan J agreed with the reasoning of Davies AJA in relation to the application under s 43A(7). In effect, Manderson is authority for so much of the approach of Foster AJA in Diaz as has been set out at [48] above and cited by Davies AJA in Manderson at [60].
52 In March 2003, this Court delivered judgment in Buller v Black (2003) 56 NSWLR 425. The President (in dissent as to the outcome) quoted with approval the reasoning of Giles JA in Diaz at [40]-[42]: see Buller at [46]. His Honour continued at [47]:
"In some circumstances it will be necessary to examine the conduct of the plaintiff's agents, and this may throw up legal and factual issues regarding the extent to which the plaintiff is affected by the inappropriate dilatoriness of appointed agents (cf Diaz ). Such issues do not arise in the present case … ."
53 Giles JA, in a judgment with which Ipp JA agreed, stated at [94], in relation to the second limb of the test:
"This, as I observed in Diaz … at [41]-[42], is intended to set an objective standard of conduct and meaning that the reasonable person in the position of the claimant would have been subjected to the delay and the subjection to the delay would have been justified. The language of experiencing the delay must have been intended to take account of other persons' conduct affecting the making of a claim."
54 There was no reference to other views expressed in Diaz, nor to Manderson.
55 In September 2003, the High Court handed down judgment in Russo v Aiello (2003) 215 CLR 643. That case concerned the application of s 43A(7) of the 1988 Act, which required that, in respect of a late claim, the Court "must" dismiss the proceedings if satisfied that the claimant "does not have a full and satisfactory explanation for the delay in making the claim". Further, as already noted, the procedural steps in question differed significantly from the present case. Nevertheless, the Court gave careful attention to the elements of the definition contained in s 40(2), corresponding with s 66(2) of the 1999 Act. In dealing with the second sentence of the provision, at [7], Gleeson CJ stated:
"It is to be noted that what the Act requires is justification for delay; not demonstration that the delay caused no harm. That does not mean that the Act is unconcerned with the presence or absence of prejudice to insurers resulting from delay. … However, while the problems that insurers might experience as a result of delays in making claims form part of the general legislative concern, the focus of the statutory concept of a satisfactory explanation is upon justifying delay, rather than excusing it. It is one thing to say the conduct is justified by reference to the way in which a reasonable person in the position of a claimant could have been expected to behave. It is another thing to say the delay ought to be excused because it caused no identifiable harm to an insurer. It is the former, not the latter, question that is raised for consideration."
56 This approach was expressly accepted by McHugh J at [25] and is consistent with the identification of "the question" which the statute presents, as explained by Gummow and Hayne JJ at [58]. These judgments are inconsistent with the proposition that there is any separate or additional test of satisfactoriness to be derived from the first sentence of the statutory provision. If there were, it would be necessary to determine what considerations would be relevant to it and to explain why questions of prejudice were not relevant. It follows that the High Court in Russo took a different view to that of Foster AJA in Diaz, with respect to this question. The test of satisfactoriness is found in the second sentence in s 66(2). Whether other considerations become relevant to the exercise of the discretionary power in s 109 is a separate question which is not presently in issue.
57 This Court returned to s 40(2) in Blackburn v Allianz Australia Insurance Ltd (2004) 61 NSWLR 632. Sheller JA, with whom the other members of the Court agreed, set out in some detail the differences of opinion in earlier decisions of the Court, including those set out above. His Honour noted the differences of view expressed by members of the Court in Diaz, also noting that the critical step in the approach of Foster AJA was flawed in the manner noted above: Blackburn at [48]. Like Diaz and Manderson, Blackburn involved a child who had suffered serious injuries in a motor vehicle accident in which the driver was her mother. In the proceedings, her mother was her tutor Her solicitor was Ms Walsh. At [49] Sheller JA concluded:
"In this case, neither the claimant nor her mother were in any way responsible for the failure to institute proceedings within time. The claimant was incapable of giving any explanation. The mother's explanation of the delay was satisfactory. She learnt of Ms Walsh's mistake and the need to obtain leave to commence proceedings on 1 September 2003, two days before the application was filed. Whether the expression 'in the position of' in s40(2) embraces only the claimant herself or embraces also her mother, the posited 'reasonable person' would have been justified in experiencing the same delay since neither knew anything about the limitation period or the need to make the application until 1 September 2003. Ms Walsh fully explained her further delay after 11 April 2003 in the cross-examination … . Applying either the test in Diaz v Truong as articulated by Hodgson JA or as articulated by Foster AJA the explanation was, within the meaning of s40(2) of the Act, satisfactory."
58 Hodgson JA made some additional remarks with which Mason P agreed. The first related to Foster AJA's view that the satisfactoriness of the explanation was confined to compliance with the second sentence in the definition. He agreed that in principle it was not, but continued at [54]:
"However, if the delay experienced by the claimant is one which a reasonable person in the position of the claimant would have been justified in experiencing, and if a full explanation for the delay is given by the claimant and the claimant's advisers, I find it difficult to envisage any circumstance in which the explanation would not be considered full and satisfactory. In particular, I do not think unsatisfactory conduct by the legal advisers would have this effect, although of course it could be relevant to whether it is just to grant the extension."
59 Figliuzzi v Yonan [2005] NSWCA 290 also considered provisions in the 1988 Act. The facts of the case differed significantly from other authorities, in that the delay in question was caused by the failure of the claimant to obtain any legal advice. This was determinative of the outcome, which was adverse to the claimant: at [100]-[104]. McColl JA, (who with Tobias JA constituted the majority) stated the test, after reference to authority including Russo, in the following terms at [128]:
"While the question in a case such as this is whether the claimant has provided an explanation for delay ( Russo v Aiello at [10]), that question is to be determined by the hypothetical objective standard invoked by the requirement that the claimant's explanation be tested against the standard of a 'reasonable person in the position of the claimant': see Russo v Aiello at [74] per Gummow and Hayne JJ."
