Consideration
18 The case below was concerned with the proper terms of Mr Rand's contract of employment. The terms of the contract were never reduced to writing. The only evidence as to its express terms came from Mr Rand, whose evidence was unchallenged.
19 In submissions put for the plaintiff below, reference was sought to be made to the provisions of the Transport Industry (State) Award. To that point, however, no claim had been advanced in the proceedings under that award. It was not in evidence. Nor had the evidence sought to establish that its terms applied to Mr Rand's employment. The defendant did not concede that the award applied to the employment. The plaintiff was given an opportunity by his Honour to amend his case to advance an award claim, which was refused. On appeal reliance on that award was also abandoned.
20 It was conceded below, that the evidence did not show any express agreement between the parties that Mr Rand would be paid at the overtime rates which he claimed. While he asked at the outset what the overtime rate would be, the only response which he received from Mr Wicker was that 'you will be paid for the overtime you work'. Consistently with that advice, he was thereafter paid for overtime at the only rate discussed, of $20 per hour.
21 His Honour was unable to conclude from the evidence that Mr Wicker had told Mr Rand that the rate of $20 per hour was the 'normal rate', that when overtime was worked, it would be paid at the rate of time and a half for the first two hours and double time thereafter. On the evidence, that view of the evidence was plainly open.
22 It was not until March 2003, after repeatedly asking about a higher overtime rate, that Mr Rand was informed by Mr Wicker that an agreement was being negotiated, which would deal with overtime. Who that agreement was being negotiated with, was not dealt with in the evidence. Mr Rand was again told that, 'You will be paid for the overtime you have worked'. Thereafter, when Mr Rand worked overtime on Saturdays, he was paid the claimed rates for overtime, but there was no such payment made for overtime worked Monday to Friday, for which he continued to be paid at the rate of $20 per hour (and later $22). When Mr Rand enquired again about the payment made to him for overtime work, he was given the same advice.
23 Whether or not the discussions to which Mr Wicker referred, resulted in an agreement which applied to Mr Rand, for increased payments when overtime was worked on Saturdays, was not revealed on the evidence. That was certainly a possibility. There was no evidence, however, from which it could be inferred that the higher payment resulted from any discussion or agreement reached between Mr Rand and the defendant.
24 The plaintiff relied on the High Court's approach in Byrne to argue that the evidence of this higher payment for overtime worked on Saturdays after March 2003, permitted the claimed term to be implied and that his Honour had erred in failing so to conclude. I am unable to accept the argument.
25 It was observed in the joint judgment of Brennan CJ, Dawson and Toohey JJ at p 442 that:
The implication which the appellants seek to make is based upon the presumed or imputed intention of the parties. In that context, the remarks of the majority in the Privy Council in BP Refinery (Westernport) Pty Ltd v Shire of Hastings [(1977) 180 CLR 266 at 283] are frequently called in aid: "(1) [the implication] must be reasonable and equitable; (2) it must be necessary to give business efficacy to the contract, so that no term will be implied if the contract is effective without it; (3) it must be so obvious that `it goes without saying'; (4) it must be capable of clear expression; (5) it must not contradict any express term of the contract." In laying down those criteria, it was recognised that there was a degree of overlap. Further, as Deane J has observed [See Hospital Products Ltd v United States Surgical Corporation (1984) 156 CLR 41 at 121.] , the cases in which the criteria in BP Refinery (Westernport) Pty Ltd v Shire of Hastings have been applied in this Court are cases in which there was a formal contract, complete on its face. He pointed out that a rigid approach should be avoided in cases, such as the present, where there is no formal contract. In those cases the actual terms of the contract must first be inferred before any question of implication arises. That is to say, it is necessary to arrive at some conclusion as to the actual intention of the parties before considering any presumed or imputed intention. And the test to be then applied was in a later case formulated by Deane J in these terms [See Hawkins v Clayton (1988) 164 CLR 539 at 573.] :
