(3) ESSB had argued that claims A and B did not fall within clause 34.9, because there was no compensable cause.
41 Lipman pointed, further, in submissions to the adjudication application in which, as I have said, clause 34.9 was explicitly disavowed (in relation to Claim A) because there was no compensable cause.
42 Finally, in this context, Lipman pointed in submissions to a number of passages in the adjudication response where ESSB had argued that clause 34.9 was the only relevant clause, but was not available.
43 Accordingly, Lipman submitted, ESSB had, in fact, addressed the clause 34.9 issue and had not been denied procedural fairness. It submitted that, if Mr Davenport had erred in finding that there was a compensable cause (as that expressions is defined by the contract) it was an error within jurisdiction; something that he was as much entitled to get wrong as to get right (to paraphrase the words of Lord Reid in Anisminic Ltd v Foreign Compensation Commission [1969] 2 AC 147, 171).
44 I do not think that Lipman's submission is correct. The thrust of ESSB's argument in its adjudication response was that the contractual term relied upon by Lipman in support of Claim A did not, in fact, authorise it. It is correct to say that ESSB supported this argument by referring to clause 34.9 as the only source of power. However, it dealt with the inapplicability of clause 34.9 very briefly by saying that, "a variation under the Contract is not listed as a "compensable cause"" and that "a variation ... is (deliberately) not a "compensable cause" giving rise to an entitlement to claim delay damages" (paragraph 29(a)(iv), (v)).
45 It is not surprising, given the explicit attitude of Lipman, that ESSB dealt with the point so briefly.
46 I have no doubt that, if Mr Davenport had notified the parties of his intention to decide Claim A by reference to clause 34.9, ESSB would have dealt with the matter in greater detail. I have no doubt that, among other things, it would have reminded Mr Davenport that (as he appears to have overlooked, or regarded as not significant) Lipman had explicitly disavowed reliance on clause 34.9 and conceded that it was not available.
47 It is correct to say that not every departure from the rules of natural justice will entitle the aggrieved party to relief: Stead v State Government Insurance Commission (1986) 161 CLR 141. But where the denial of natural justice affects, in a real way, the ability of the aggrieved party to put its case on a particular issue, relief will ordinarily be granted. As the High Court put it in Stead at 147:
"All that the appellant needed to show was that the denial of natural justice deprived him of the possibility of a successful outcome. In order to negate that possibility, it was, as we have said, necessary for the Full Court to find that a properly conducted trial could not possibly have produced a different result."
48 In my judgment, that principle, although stated in terms of Court proceedings, is capable of application directly to the present case. It would have to be demonstrated that, had Mr Davenport raised with the parties his intention to decide Claim A by reference to clause 34.9, the further submissions of the parties (or of ESSB in particular) "could not possibly have produced a different result".
49 Given that it is common ground between the parties that clause 34.9 could not apply because there was no compensable cause, and given that the common position of the parties appears to me to be correct, I do not think that this test could be met. That is because I cannot accept that a reasonable adjudicator in the position of Mr Davenport would continue to hold a view of the contract that both parties would have said was wrong; particularly where, as I have just indicated, I think that their position was correct.
50 I therefore conclude that ESSB has made out its case in relation to Claim A on the basis that it was denied natural justice. It is, accordingly, unnecessary for me to consider ESSB's alternative arguments on Claim A.
51 I add only that the question of natural justice affects both parties. Clearly enough, it affects the party against whom the unheralded argument is deployed. In this case, ESSB was directly affected because it was denied the possibility of a successful outcome on this point. However, the party in whose favour the unheralded argument is deployed is equally affected. That is because that party may be deprived, through the process of judicial review, of the benefit of a determination that it could have sustained on other grounds. This latter point may not be particularly relevant to the present case, because of the view that I have expressed as to the correct basis upon which the parties jointly approached clause 34.9. However, in other cases, it is clear that the position may not be so obvious; and, therefore, that a determination in breach of the rules of natural justice may work injustice on the successful party.
Analysis: Claim B
52 The issue relating to Claim B is whether it was open to Mr Davenport to conclude that clause 56.4 did not apply. ESSB accepts that it was open to him to err, and that if he erred within jurisdiction, relief would not lie. It said, however, that clause 56.4 was so obviously a complete answer to Claim B, that Mr Davenport's alternative view must mean, necessarily, that he had not "considered" the matter as required by s 22(2)(b) of the Act.
53 I dealt with what is entailed in the obligation to consider something in Musico at [117] as follows:
"117 An obligation to consider something requires "an active intellectual process directed at that" thing: Tickner v Chapman (1995) 57 FCR 451, 462 (Black CJ); or the application of one's own mind to it by obtaining an understanding of the relevant facts, circumstances and contentions, ibid at 476 (Burchett J); see also at 495 (Kiefel J). In any case where a determination of the issues before an adjudicator depended on the terms of the contract and their effect - i.e., to what obligations, properly construed, did the contract give rise - an adjudicator must necessarily form a view of these issues in the process of deciding the question of entitlement. In any such case, it would be impossible for an adjudicator to come to a view as to the quantification of a party's contractual entitlement without understanding that entitlement."
54 On the face of the Determination, Mr Davenport did consider the application of clause 56.4. As I have pointed out, he referred to it and gave reasons - admittedly brief - for saying that it had no application. In those circumstances, it is very hard to argue that he did not "consider" the clause and its application to the facts of the case.
55 It may be that, by analogy with the principles of Wednesbury unreasonableness (Associated Provincial Picture Houses Ltd v Wednesbury Corporation [1948] 1 KB 223), purported consideration of a point by an adjudicator could not be said to satisfy the obligation imposed by s 22(2)(b) or (d) if no reasonable adjudicator, having considered the point, could come to the conclusion that was expressed. However, because I have come to the view that Mr Davenport's conclusion on clause 56.4 can be supported, I do not express this as a concluded opinion.
56 ESSB submitted (to Mr Davenport and to me) that clause 56.4 was invoked because, as clause 56.3(b) contemplated might happen, the relevant delay was caused by the requirements of Woolworths. It relied on a letter of 4 June 2002 that was attachment 7 to the adjudication response. (Indeed, a subsidiary complaint made by ESSB was that Mr Davenport had failed to "consider" this document.)
57 I am not certain that the document in question goes as far as it should if ESSB's argument is to be accepted as a matter of fact. However, I am prepared to assume that it does.
58 There was other material, which Mr Davenport could accept if he wished, showing that Woolworths absolutely prohibited Lipman from carrying out work in the relevant area: see paragraph R 10.2 of Lipman's submissions attached to its adjudication application. Lipman submitted that the prohibition of work was conceptually different to the modification (under direction) of the hours or method of work. It submitted, therefore, that it was open to Mr Davenport to conclude, as he did, that clause 56.3(b) had no operation on the facts relevant to Claim B. If it did not, then clause 56.4 could not afford a defence to Claim B.
59 One possible difficulty with this argument is that Mr Davenport did not articulate it as a basis for his conclusion that clause 56.4 did not provide a defence to Claim B. Having said that, however, in my judgment, ESSB's challenge to Claim B fails. I do not think that it can be said, reading the Determination as a whole, that Mr Davenport failed to "consider" the applicability and effect of clause 56.4. If he came to the wrong conclusion (and I make no finding that he did), he was entitled so to do.
60 Further, I think, Lipman's submission should, in principle, be accepted. There was material that would have justified Mr Davenport in reaching the conclusion that he did. Whether or not he relied upon that material, and whether or not that conclusion was "correct", are different matters; but assuming incorrectness (and I make no finding of incorrectness) there is no reviewable error.
61 I do not think that ESSB's subsidiary complaint is made out. ESSB did not, in its adjudication response, refer to the document at tab 7 in connection with Claim B. It referred to it only in connection with Claim D. If ESSB did not think it worthwhile to draw the document to Mr Davenport's attention in connection with Claim B, I am unable to see how he can be said to have erred (which, in any event, is not shown) if he failed to "consider" the document in the context of Claim B.
