26 The payment claim was in the form of a tax invoice from the defendant to the plaintiff referring to the job by its address, the contract value and it contained a statement of the value of work completed and claimed. This was set out under six headings which were number, date, value of claim, date paid, amount paid and amount. There were four items under these headings and it is apparent that they are a reference to three previous invoices issued by the defendant to the plaintiff on the three dates specified in the claim. The invoice carried a notation which was required under s13(2)(c) of the Act. The real complaint of the plaintiff is that the payment claim merely referred to the value of the various claims made previously and made no specific reference to work of any kind. It is to be noted that under s13(2)(a), the payment claim must identify the construction work to which the progress payment relates. This seems perfectly plain to me as on its face the payment claim incorporates by reference the earlier tax invoices. These invoices themselves clearly give a description of the work and the amount claimed for each item of work. In my view there is an appropriate identification of the construction work to which the progress payment relates.
27 It was also suggested that the payment claim did not identify the basis on which the amounts were claimed and pointed to the fact that the payment claim, although referring to a contract value of $128,760.90 did not refer to a percentage of the claims that were complete. Under s13(2)(b) all the payment claim has to do is indicate the amount of the progress payment that the claimant claims to be due. On the face of the payment claim, the document does this as it sets out the value of the claim in respect of each invoice and gives credit for the amounts that have been paid in respect of that invoice. It is plain what the amount is that the claimant claims to be due.
28 There was also reference made to the fact that it is not apparent on what basis the contractual claim is advanced, but I do not think that this is relevant. The payment claim only needs to set out the matters required by the section. In my view the payment claim does comply with s13(2) of the Act.
The failure by the defendant to properly notify the plaintiff of the Adjudication Application such that the plaintiff was given no opportunity to file an adjudication response
29 The plaintiff's claim is that there has been a breach of the rules of natural justice in respect of the provision of notices required under the section. The extent to which the Court may declare void a determination has been dealt with definitively by the Court of Appeal in Brodyn Pty Limited v Davenport [2004] NSWCA 394. In the majority judgment Hodgson J distinguished between the basic and essential requirements, and the more detailed requirements for the purposes of determining whether a breach may make the determination void. He said:
"53 What then are the conditions laid down for the existence of an adjudicator's determination? The basic and essential requirements appear to include the following:
1. The existence of a construction contract between the claimant and the respondent, to which the Act applies (s.7 and s8).
2. The service by the claimant on the respondent of a payment claim (s.13).
3. The making of an adjudication application by the claimant to an authorised nominating authority (s.17).
4. The reference of the application to an eligible adjudicator, who accepts the application (s.18 and s19).
5. The determination by the adjudicator of this application (s.19(2) and s21(5)), by determining the amount of the progress payment, the date on which it becomes or became due and the rate of interest payable (s.22(1)) and the issue of a determination in writing (s.22(3)(a)).
54 The relevant sections contain more detailed requirements: for example, s.13(2) as to the content of payment claims; s.17 as to the time when an adjudication application can be made and as to its contents; s.21 as to the time when an adjudication application may be determined; and s.22 as to the matters to be considered by the adjudicator and the provision of reasons. A question arises whether any non-compliance with any of these requirements has the effect that a purported determination is void, that is, is not in truth an adjudicator's determination. That question has been approached in the first instance decision by asking whether an error by the adjudicator in determining whether any of these requirements is satisfied is a jurisdictional or non-jurisdictional error. I think that approach has tended to cast the net too widely; and I think it is preferable to ask whether a requirement being considered was intended by the legislature to be an essential pre-condition for the existence of an adjudicator's determination.
55 In my opinion, the reasons given above for excluding judicial review on the basis of non-jurisdictional error of law justify the conclusion that the legislature did not intend that exact compliance with all the more detailed requirements was essential to the existence of a determination: cf. Project Blue Sky Inc. v. Australian Broadcasting Authority (1998) 194 CLR 355 at 390-91. What was intended to be essential was compliance with the basic requirements (and those set out above may not be exhaustive), a bona fide attempt by the adjudicator to exercise the relevant power relating to the subject matter of the legislation and reasonably capable of reference to this power (cf. R v. Hickman; Ex Parte Fox and Clinton (1945) 70 CLR 598), and no substantial denial of the measure of natural justice that the Act requires to be given. If the basic requirements are not complied with, or if a purported determination is not such a bona fide attempt, or if there is a substantial denial of this measure of natural justice, then in my opinion a purported determination will be void and not merely voidable, because there will then not, in my opinion, be satisfaction of requirements that the legislature has indicated as essential to the existence of a determination. If a question is raised before an adjudicator as to whether more detailed requirements have been exactly complied with, a failure to address that question could indicate that there was not a bona fide attempt to exercise the power; but if the question is addressed, then the determination will not be made void simply because of an erroneous decision that they were complied with or as to the consequences of non-compliance."
30 It is plain that a substantial denial of the measure of natural justice that the Act requires to be given can lead to a determination being void. His Honour went on to describe the measure of natural justice that the Act requires in paragraph 57, in these terms:
"57 The circumstance that the legislation requires notice to the respondent and an opportunity to the respondent to make submissions (ss.17(1) and (2), 20, 21(1), 22(2)(d)) confirms that natural justice is to be afforded to the extent contemplated by these provisions; and in my opinion, such is the importance generally of natural justice that one can infer a legislative intention that this is essential to validity, so that if there is a failure by the adjudicator to receive and consider submissions, occasioned by breach of these provisions, the determination will be a nullity. On this basis, I agree with the result reached in Emag Constructions Pty. Ltd v. Highrise Concrete Contractors (Aust) Pty. Ltd [2003] NSWSC 903. I note there is some controversy as to whether denial of natural justice generally results in voidness or voidability (see for example Ridge v. Baldwin [1964] AC 40, Durayappah v. Fernando [1967] 2 AC 337, Banks v. Transport Regulation Board (Vic ) (1968) 119 CLR 222 at 233, Calvin v. Carr [1980] AC 574 at 589-90, Minister for Immigration v. Bhardwaj (2002) 209 CLR 597 at 630-34); but in my opinion, in cases such as this where there is a disclosed legislative intention to make a particular measure of natural justice a pre-condition of validity, failure to afford that measure of natural justice does make the determination void."
31 The provisions to which His Honour refers are of course the provisions for submission of various responses to the Adjudicator in the course of making his determination. His Honour has indicated the ambit of the measure of natural justice the Act requires by extending it beyond the basic and essential requirements, which he identified in paragraph 53, to cover the particular process during the Adjudication that he identified in paragraph 57.
32 It seems to me that the question of any breach of natural justice must also take into account whether or not the plaintiff was given a copy of the Adjudication Application as required under sub-section 5 of s17.
33 The Act requires that a payment claim be served within 12 months after the work to which it relates was last carried out (s13(4)(b)). A payment schedule is required to be served within 10 business days after service of the payment claim (s14(4)(b)). If a party intends to apply for Adjudication, that party must notify the other of its intention within 20 business days of the due date of the payment and allow a further five business days for the provision of a payment schedule before the Application is made to the authorised nominating authority and served on the other party (s17(2)). An adjudication response can be made either five business days after the copy of the Application is served, or two business days after receiving notice of the Adjudicator's acceptance (s20(1)). Importantly an adjudication response can only be made where a payment schedule has been made within the times set out above (s20(2A)) and can only include information set out in the payment schedule (s20(2B)). There is no time frame for when the Adjudicator must accept the Application. After the acceptance of the Application, the Adjudicator must determine the matter within ten days or in a time agreed by the parties (s21(3)).
