Percentage of Preliminaries entitlement based on 22%
Respondent certification of the current payment claim
3. I consider that the previous payment of 55% to 60% of the value of 'Preliminaries' indicates that the item has not been paid on the basis of the percentage of work complete[d]. I then conclude that I do not agree with the Respondent's submission that it has been the practice on the project that 'The entitlement to preliminaries, overhead and profit arises as scope is completed'. [Footnotes omitted]
The reference to "60%" arose from the fact that the Adjudicator had calculated that the amount paid corresponded to the 60% of the work done, not 55% as claimed by Fulton Hogan.
- It was common ground that an adjudicator appointed under the Act is obliged to give reasons for his or her decision that meet the minimum requirements of reasons for the purposes of the Act. Expressed in terms of unreasonableness, Fulton Hogan submitted that the relevant standard was that stated by Hayne, Kiefel and Bell JJ in Minister for Immigration and Citizenship v Li (2013) 249 CLR 332; [2013] HCA 18 at [76]:
Even where some reasons have been provided, as is the case here, it may nevertheless not be possible for a court to comprehend how the decision was arrived at. Unreasonableness is a conclusion which may be applied to a decision which lacks an evident and intelligible justification.
- Li was a case concerned with the exercise of a discretion conferred on a Tribunal exercising powers under the Migration Act 1958 (Cth). However, it was not suggested that different principles applied in this case. Consequently, the question is whether the reason advanced by the Adjudicator for preferring a time basis for calculating the amount that should be allowed in respect of preliminaries lacked an evident and intelligible basis.
- The Adjudicator's reasoning appears to have two steps. The first was to conclude from the available facts that preliminaries in the past had not been paid on a value-of-work-completed basis. The second was to infer from that that a time basis should be applied.
- The second of these steps appears to be rational in the context of what else the Adjudicator said. The Adjudicator pointed out that there were two ways of apportioning preliminaries. She also appointed out that the more common one was the time basis. They were conclusions that she was clearly entitled to reach. Accepting that the parties had not adopted the value-of-work-completed basis, she concluded that a time basis was appropriate. Although her reasoning could have been fleshed out, that seems to me to be a rational conclusion to reach.
- The first step in the Adjudicator's reasoning process is more difficult to follow. It appears to rest on a misunderstanding of the facts and of Fulton Hogan's submissions. What the Adjudicator appears to be saying is that Fulton Hogan had previously accepted that a payment of 55% to 60% of the value of preliminaries was appropriate. However, it contended that (by value) at the time of the payment claim only 22% of the work had been done. Consequently, it had not applied the method of apportionment to preliminaries for which it contended. However, as I have said, that appears to involve a misreading of the submission advanced by Fulton Hogan. Fulton Hogan's submission appears to be to the effect that the appropriate amount for preliminaries was 22% but it was prepared to allow 55%, not that 55% represented the amount of some past payment.
- Even so, in my opinion, the Adjudicator's error does not involve a failure to give a rational reason for her decision. Rather, it involves a misreading of a poorly expressed submission, resulting in a misunderstanding of the facts. That was an error that the Adjudicator was entitled to make. Consequently, I do not accept that the Determination was defective in that respect.
