Terms of the contract
38 It is clear that initially, there was a contract between the previous owner and Executive, on the basis of the September 1998 tender documents. In my opinion, no doubt is thrown on this by the "contract signature" document of 1999. This contract provided relevantly for 15 minute coverage, to be provided by four cleaners.
39 I am not satisfied, on the balance of probabilities, that this contract was displaced by the letter of 18 October 1999. If the only question had been whether that letter had been sent, I am inclined to think that such an inference could be drawn from the presence of the letter among the business records of the previous owner. However, there is also a question of whether, if it had been sent and received, its terms were accepted. There is no written or oral evidence directly supporting such an acceptance.
40 Mr Rewell SC for Bevillesta submitted that an inference should be drawn that the terms were accepted, particularly because of Liberty's failure to call Mr Kidd.
41 This submission would have had force if Executive itself was the relevant defendant, with Liberty conducting the case on behalf of its insured. However, in my opinion it has little if any force in circumstances where Liberty has been sued direct pursuant to s 6 of the Law Reform (Miscellaneous Provisions) Act 1946. In my opinion, it cannot be said that Mr Kidd is in Liberty's "camp", or that Liberty has any particular reason to have confidence in his evidence. If it can be said that Mr Kidd would be expected to be called by Liberty rather than by Bevillesta, that expectation could not be considered a strong one. Accordingly, in my opinion, if it is a case in which an inference can be drawn in accordance with the principle in Jones v Dunkell (1959) 101 CLR 298, the inference could not be considered a strong one. Accordingly, I would not be prepared to infer that the terms of the letter of 18 October 1999 were accepted.
42 In circumstances where Executive continued to provide cleaning services to Bevillesta, after it acquired the shopping centre, I would infer that there was a contract between Executive and Bevillesta on the same terms as the contract that existed before Bevillesta's purchase with the previous owner.
43 It is clear that the contractual terms changed in May 2001. As a result of the new cleaning schedule, the cleaner was obliged to provide only two cleaners on Mondays between 4pm and 5pm, three cleaners between 5pm and 5.30pm and two cleaners between 5.30pm and 6pm. In those circumstances, in my opinion it was no longer an obligation of Executive to provide 15 minute coverage of relevant areas at these times. The question then is, what were the relevant obligations of Executive.
44 Mr Rewell submitted that the primary judge had erred in finding that the obligation was to provide only two cleaners at the relevant times, and did not further consider what the obligation of the cleaner was. Mr Rewell submitted that the ongoing obligation of the cleaner must have been to provide coverage commensurate with the continuing personnel, that is at 30 minute intervals in those periods when there were two cleaners and 20 minute intervals in those periods when there were three cleaners. At the very least, he submitted, there must have been a requirement for coverage within the period of 40 minutes during which the squashed orange was shown to be present.
45 In my opinion, it is significant, as submitted by Mr Polin for Liberty, that Mr Savill gave no evidence of any instructions given to the cleaners or to the security guard as to responsibility for detection of spillages and, apart from the evidence referred to above about 15 minute coverage at lunchtime, no evidence as to what the practice was after May 2001.
46 As submitted by Mr Polin, the obligations of the cleaning contractor went far beyond the detection and cleaning of spillages and other hazards (see Blue 79-85); so particularly in circumstances where some responsibility for detection of spillages was accorded to the security company, it would not be appropriate to infer that there should be simply a proportionate adjustment of the coverage, as submitted by Mr Rewell.
47 Accordingly, in my opinion, while the cleaning contract did undoubtedly still include an implied obligation to exercise reasonable skill and care, it did not in my opinion include any obligation as to any particular frequency of inspection for spillages.
48 Turning to the question of assignment, in my opinion very little weight can be given to the letter, originally bearing date 21 May 2001, which purported to emanate from Services and referred to an assignment to Services. I would infer that the correct date of the letter is 1 May 2001, and that the letter of 3 May 2001 was a response to it. The letter of 3 May 2001 was directed to Executive, and made no reference to any assignment.
49 Further, in my opinion, the oral evidence of Mr Savill carries very little weight. An assignment would have to be by words and/or writing and/or conduct. The evidence of Mr Savill was thus of a conclusion of mixed fact and law, without identifying or giving evidence of relevant facts. If it had been objected to, it would have been rejected as inadmissible.
50 In my opinion, the invoices and cheques have far greater weight, in suggesting that Executive continued to be the cleaner. It is not to the point that the invoices were addressed to a company providing management services to Bevillesta rather than Bevillesta itself.
51 Accordingly, in my opinion, the presumption of continuance was not displaced, and the relevant contract was between Bevillesta and Executive.
