(c) must state that it is made under the Act.
18 As will be seen from what follows below, my own view is that one commences with identifying what the statutory scheme puts forward as constituting a payment claim. A payment claim clearly is a claim to an entitlement to be paid a progress payment. The whole notion of a payment claim, it seems to me, requires as an essential condition thereof that the document by which the payment claim is put forward, include, whether in shorthand or in longhand and whether by one means or another, sufficient information to identify what the claim is.
19 There is a powerful argument that this effectively means that the statutory regime requires that the claim to be valid must be comprehensible by the respondent. The argument is supported by reference to the whole of the statutory scheme and most particularly by reference to the following considerations:
· section 22(2)(c) clearly suggests (as does the whole of the environment being dealt with) [cf McDougall J in Multiplex supra at 76] that there will have been relevant documentation provided by the claimant in support of its claim;
· the requirement stipulated for in section 14 (3) for the respondent to indicate why the scheduled amount is less than the claimed amount [and if it is less because the respondent is withholding payment for any reason, then to give the respondents reasons for withholding payment], can only be justified by the proposition that the payment claim will identify in a fashion comprehensible to a respondent, just what the claim is;
· the statutory scheme is for an application [called an adjudication application]. The application must "relate to the payment claim" [section 22(2)(c)]. The application is for the adjudication of no more and no less than the payment claim as contradicted/traversed by the payment schedule.
20 However, as earlier observed, there are no words within section 13 (1) which require the claimant to do otherwise than:
· to identify the subject construction work to which the progress payment relates [subsection (1) (a)];
· to indicate the amount of the progress payment that the claimant claims to be due [subsection (1) (b)];
· to state that the claim is made under the Act. [subsection (1) (c)].
21 Ultimately it seems to me that the accepted principles of statutory construction simply do not permit the Court to take the further step of holding that in order to be valid, a payment claim must be comprehensible by the respondent in terms of its supporting materials [cf especially the abovementioned citation from McHugh J in Newcastle City Council v GIO General].
Approaching the question in terms of section 20 (2B)
22 The primary touchstone it seems to me, is section 20 (2B). Whilst a claimant which provides the most minimal amount of information in its payment claim may even so, be seen to technically comply with section 13, such a claimant will expose itself to an abortive adjudication determination if it be that:
· the respondent is simply unable to discern from the content of the payment claim, sufficient detail of that claim to be in a position to meaningfully verify or reject the claim: hence not then being in a position to do otherwise than to reject the whole of the claim on the basis of its inability to verify any part of the claim;
· the claimant then elects to include the missing detail in the adjudication application with the inexorable consequence that the respondent is barred by section 20 (2B) from dealing with that detail/matter in its adjudication response;
· the adjudicator relies in determining the adjudication application upon the detail supportive of the payment claim which first emerged as part of the adjudication application
23 For those reasons whilst it is not permissible to construe section 13 as providing that in order to be a valid payment claim, such a claim must do more than satisfy the requirements stipulated for by subsection 2 (a), (b) and (c), the consequence to a claimant which does not include sufficient detail of that claim to be in a position to permit the respondent to meaningfully verify or reject the claim, may indeed be to abort any determination.
Approaching the question in terms of the adjudicator's power
24 The matter may also be analysed by reference to the power of an adjudicator. An adjudicator does not have the power to consider materials supplied by a claimant in its adjudication application which go outside [ie fall outside the ambit or scope of] the materials which were provided in the payment claim, for the reason that the adjudicator only has power to make a determination based upon:
· The payment claim [together with the claimant's submissions (and relevant documentation) in the adjudication application, which submissions have to have been "duly made by the claimant in support of the (payment) claim": see section 22 (2) (c)].
· The payment schedule (if any) [together with the respondents submissions (and relevant documentation) in the adjudication response, which submissions have to have been "duly made by the respondent in support of the (payment) schedule": see section 22 (2) (d)].
· The provisions of the Act: see section 22 (2) (a).
· The provisions of the construction contract from which the application arose: see section 22 (2) (b).
· The results of any inspection carried out by the adjudicator of any matter to which the claim relates: see section 22 (2) (e).
25 The emphasis upon submissions "duly made" makes clear that the scheme really addresses the issues which have been thrown up once the payment claim has been served and the responsive payment schedule then served. The steps which follow generally concern the materials to be exchanged and most particularly furnished to the adjudicator. The adjudication application will relate to a particular payment claim and payment schedule [section 17 (3) (f)]. The central significance of the entitlement of the applicant to include submissions as part of its adjudication application is because those submissions have to be supportive of the payment claim. Those submissions cannot constitute a payment claim or part of it. The central significance of the entitlement of the respondent to include submissions as part of its adjudication response is because those submissions have to be supportive of the payment schedule. Those submissions cannot constitute a payment schedule or part of it.
Section 21 (4) - additional submissions
26 Whether or not any of these problems may be addressed by the adjudicator requesting further written submissions from either party may become the subject of curial examination on another occasion. However it would seem unlikely that the legislature would have intended the provisions of section 21 (4) (a) and (b) to permit a radical departure from the statutory scheme described above. Rather it seems likely that these sub-sections are to be read as permitting no more than additional submissions which clarify earlier submissions: those earlier submissions being constrained in the manner above described.
Turning from the general to the particular
27 If one turns from the general to the particular, the circumstances in which a claimant for the first time treats in the adjudication application with parameters which were not telegraphed in the payment claim may occur across a number of different situations as for example:
· where the claimant for the first time advances a new contractual basis for a payment claim in the adjudication application;
· where the claimant for the first time seeks to deploy in the adjudication application, supporting documentation of one type or another.
28 These situations may have differing results.
New contractual basis
29 The first situation seems to me to generally be quite plain. The abortive adjudication determination likely to result from the advancing [, within the adjudication application] of a new contractual basis for a payment claim, has already been explained.
