(3) Have all preconditions which the Act makes essential for the existence of a determination within the meaning of the Act been satisfied ( TransGrid at [29])?
45 These formulations of the test suggest strongly that, even if the list of essential requirements is not to be regarded as closed (Brodyn at para [55]), nonetheless the class of matters that, if not satisfied, will make a decision reviewable may be regarded as preconditions to the existence of a valid determination, rather than errors in the determination itself. Of course, as Hodgson JA noted in TransGrid at para [29], the error may be manifested in the determination - by the adjudicator erroneously deciding that an essential precondition has been satisfied when in fact it has not. But the language in both Brodyn and TransGrid suggests strongly that the factors to be considered are anterior rather than interior: matters that must exist before there can be an adjudication at all.
46 Further, I think, it is necessary to bear in mind that in Brodyn at para [54] Hodgson JA said that stating the enquiry in terms of jurisdictional or non jurisdictional error "tended to cast the net too widely". It follows, I think, that the basic and essential requirements, or essential preconditions, are more limited in scope than those matters which, under the pre-Brodyn approach, were considered to be jurisdictional in nature.
47 I do not think that an error of the kind presently assumed - awarding, as part of the adjudicated amount of a progress payment, an amount for delay damages under cl 34.9 or interest under cl 37.5 - can be said to be a breach of a basic and essential requirement for, or an essential precondition of, a valid determination.
48 There must be, among other things, a construction contract between the claimant and the respondent, and a payment claim served by the claimant on the respondent. The entitlement to serve a payment claim is by s 13(1) of the Act given to "[a] person referred to in section 8(1) who is or who claims to be entitled to a progress payment" (emphasis supplied). The person referred to in s 8(1) is one who has undertaken to carry out construction work, or supply related goods and services, under a construction contract.
49 It must follow that there can be a payment claim for the purposes of the Act (so that, by its service on the respondent, the second basic and essential requirement identified by Hodgson JA in Brodyn at para [53] is satisfied) even if the payment claim is comprised entirely of, or includes, an amount that is not "for" construction work. A person may be found not to be entitled to a claimed progress payment, or part, for any number of reasons. The work may not have been done (and there may be no contractual entitlement to payment in advance); the work may have been done defectively and there may be a valid set-off for the cost of rectification; the work may be overvalued; there may be a valid set-off for liquidated or other damages; the claim may not be "for" construction work (or the supply of related goods and services) at all; or there may be other disqualifying features. However, the payment claim will be effective, for the purposes of the Act, by reason of the claimed entitlement. The process that the Act contemplates is that the respondent will submit a payment schedule answering the claim. If the claimant and the respondent cannot agree, then the claimant may submit the payment claim to adjudication. I cannot see how a claim that is invalid because the amount claimed is not "for" construction work is different in principle to a claim that is invalid because it is grossly overvalued. In each case (and in the case of all the other possible defences to which I have referred) the adjudicator may determine the validity of the claim. That is simply a consequence of the exercise by the adjudicator in the particular case of the powers and duties entrusted to her or him by the Act.
50 To put it another way, I think that the jurisdiction entrusted by the Act to adjudicators includes the power to determine whether (assuming it to be a relevant consideration) a particular amount claimed is "for" construction work. That is because, in essence, the adjudicator's function is to determine, in respect of the payment claim that is the subject of the adjudication application, the issues raised in it and in the payment schedule. Those issues may include those referred to in para [45] above, and no doubt more. All those matters are "within jurisdiction". They form part of, not preconditions to, the jurisdiction.
51 This conclusion is supported by the structure of the Act. Section 13(2) of the Act (not a basic and essential requirement or essential precondition - see Brodyn at [54]) requires, among other things, that a payment claim identify the construction work (etc) to which the progress payment claimed relates. Section 14(3) requires, where the amount proposed to be paid by the respondent is less than the claimed amount, that the payment schedule indicate why. Section 17(3)(h) provides that an adjudication application may contain such relevant submissions as the claimant chooses. Section 20(2)(c) provides that an adjudication response may contain such relevant submissions as the respondent chooses. However, the respondent cannot in its adjudication response rely on any reason for withholding payment unless that reason has been included in the payment schedule: s 20(2B). An adjudicator is bound to consider the provisions of the Act, the provisions to the construction contract, the payment claim and payment schedule and submissions made by the claimant and respondent respectively and the results of any inspection: s 22(2). It seems to follow from all this that, if the point that an amount claimed is not "for" construction work is not taken in the payment schedule, it cannot thereafter be relied upon by the respondent in the adjudication process. The adjudicator would be bound to determine the matter on the basis of the material to which she or he could properly have regard; and if the adjudicator decided that all the reasons advanced by the respondent were invalid, the adjudicator would determine the amount of the progress payment in favour of the claimant.
52 In those circumstances, the adjudicator would have carried out in full, and in a relevantly unchallengeable way, her or his functions under the Act. Yet if the submissions for Coordinated were correct, the determination would still be void if the determined amount, or part, were not "for" construction work. It strikes me as unlikely in the extreme that the legislature intended that the procedure could be followed through faithfully and (be it assumed) accurately as to every issue raised by the parties, yet still be a nullity because of an issue that was not raised. But that, I think, is the necessary consequence of Coordinated's submission in the particular circumstances postulated.
53 I therefore conclude that if (assuming but not deciding) it was not open to Mr Parnell or Mr Sarlos to include, in the adjudicated amount of the respective progress payments, an amount for delay damages under cl 34.9 or interest under cl 37.5, the fact that they included such amounts in the adjudicated amount does not render their determinations void.
Alternative argument based on Project Blue Sky
54 Coordinated submitted, basing itself on what was said in Project Blue Sky by McHugh, Gummow, Kirby and Hayne JJ at 393 [100], that even if its submissions based on Brodyn were not accepted (as I have held that they should not be accepted), nonetheless, the determinations of Messrs Parnell and Sarlos were each made in contravention of the Act, because in each case they allowed as part of the determined amount of the progress payment an amount that was not "for" construction work. Accordingly, Coordinated submitted, the determinations were relevantly "unlawful" and it was entitled to injunctive relief restraining the taking of any further action based on those unlawful determinations.
55 I do not think that this submission should be accepted. I do not think that it was relevantly unlawful for Messrs Parnell and Sarlos to decide this question as they did. In saying this, I continue to make the assumption that each determination included an amount that was not "for" construction work, and that, as Coordinated submitted, it was not open to Messrs Parnell and Sarlos to include such amounts in the adjudicated amount of the respective progress payments.
Third and fourth issues: interest - point not taken or "de minimis"
56 The conclusion to which I have come on the first and second issues means that it is not necessary to consider the third and fourth issues.
Fifth and sixth issues: EOTs 3 to 6
57 Messrs Parnell and Sarlos acknowledged that these claims arose out of EOTs 1 and 2, which had been the subject of consideration by Mr Makin. However, in each case, they noted that the particular claims pressed before them were for damage said to have been sustained at a time after the expiry of the period of time covered by EOTs 1 and 2. Thus, they concluded that s 22(4) did not apply.
58 In my judgment, they were either correct so to conclude or, alternatively, it was open to them on the facts so to conclude. But in any event, even if they were wrong, there was no contravention of a basic and essential requirement for the existence of a valid determination. Hodgson JA referred to s 22 in Brodyn at para [54] as one of the "more detailed requirements" of the Act. In para [55], his Honour said that "the legislature did not intend that exact compliance with all the more detailed requirements was essential to the existence of a valid determination." I read what his Honour said in para [55] as applying to, among other things, the more detailed requirements listed in para [54]. This is sufficient to answer Coordinated's submission. But even if it were open to me to consider the matter afresh, I would conclude, basically for the reasons already given in respect of the first and second issues, that s 22 is not a precondition to the existence of a valid determination. It is a matter interior, rather than anterior, to the determination.
Seventh and eighth issues: escalation costs claims 1 and 2 - s 22(4)
59 Again, Messrs Parnell and Sarlos held that these claims, although arising out of the circumstances that gave rise to EOTs 1 and 2, were manifestations of separate or additional loss. Thus, they concluded, s 22(4) did not apply.
60 Again, I think, they were either correct so to conclude or, alternatively, it was open to them on the facts so to conclude. But again, if they were wrong, I would hold, for the reasons just given in relation to the fifth and sixth issues, that they did not thereby contravene any basic and essential requirement to the existence of a valid determination.
Ninth issue - reference date
61 It was common ground that the reference dates under the contract were the last day of each month. The payment claim that was the subject of Mr Parnell's adjudication was dated, and apparently prepared on, 29 September 2004. On that date, it was faxed to Hargreaves' consultant, apparently for submission to Coordinated. The evidence makes it clear that it was not given to Coordinated until on or after 30 September 2004. The consultant added some further documents to the claim before submitting it to Coordinated.
62 I therefore find, as a matter of fact, that the payment claim in question was submitted on or shortly after a reference date - namely, 30 September 2004. It follows that this issue must be decided against Coordinated as a matter of fact. It is therefore unnecessary to consider, among other things, Hargreaves' defence based on estoppel. Nor is it necessary to consider whether the payment claim could be regarded as one made on or from the previous reference date, 31 August 2004. (This relates to the circumstance that the previous "application for progress payment" given by Hargreaves to Coordinated did not contain in full the statement required by s 13(2)(c) of the Act).
Conclusion and order
63 It follows that each of the challenges to the determinations by Messrs Parnell and Sarlos fails. I therefore order that the summons be dismissed. Unless the parties wish to argue otherwise, costs should follow the event; but if any party wishes to argue for a different order, I will hear argument on a date to be arranged with my associate. Any application for a different costs order is to be made within 7 days of the publication of these reasons.
