58 It is not clear whether the crane that Van Seumeren was "keen to supply" (to use the words of the letter of 27 March) was a CC4800 or its equivalent, or a CC2600 or an MDC3500. The letter is ambiguous and it is difficult to come to a reliable view as to what Van Seumeren intended. Although, at the commencement of the trial, the letter was tendered as an exhibit to an affidavit by Mr Bradbury, no person was asked about its contents, save in the re-examination of Mr Bradbury. Thus, the appellant asked Mr Burns no questions about it in his evidence in chief and the respondent did not cross-examine him in regard thereto. Although the letter, in effect, was referred to by Mr Bradbury in his evidence in chief, he was not cross-examined about it. No representative of Van Seumeren was called to testify.
59 In all the circumstances (that is, the omission of both parties to deal adequately with the letter in the questioning of the relevant witnesses) and in the light of the onus on the appellant, I would regard the letter as raising a question as to the unwillingness of Van Seumeren to provide a crane in accordance with the contract.
60 Mr Cochrane referred to a "safe work method statement" dated 20 February 1997 which recorded that a CC4800 crane would be on site when the appellant carried out the work it had contracted to perform at Homebush. Mr Burns sent the safe work method statement to Multiplex on 13 March 1997 and thereby represented that as at that date the appellant believed that a CC4800 crane would be forthcoming. In cross-examination Mr Burns said, in effect, that the reference to a CC4800 crane was a mistake. Mr Burns was regarded as a credible witness and there is no reason to disbelieve this explanation. At the date in question he was unlikely to have known about the availability of cranes. I do not think that the work method statement is a helpful document on this issue.
61 There was no other evidence relied on by the respondent as to the existence of a CC4800 crane that was potentially available to it through Van Seumeren, and as to the potential availability from the same source of equivalent cranes.
62 In light of the onus on the appellant, however, it was not sufficient for the appellant to point to the paucity of evidence as to available CC4800 or equivalent cranes. It was for the appellant to prove affirmatively that the respondent was wholly and finally disabled from performing its contractual obligations.
63 Mr Willmott sought to do this by relying, largely, on the letter of 20 March 1997 from Van Seumeren to the appellant in which it asserted that it could not "provide an unconditional guarantee that our Demag CC4800 will be available to be on site on 14-07-97" and in which it stated that it had a verbal contract with the respondent for providing an MDC-3500 for the work at Homebush.
64 Coupled with this piece of evidence is the fact that the respondent tacitly accepted in its facsimile of 24 March 1997 that it would not be possible for Van Seumeren to supply a CC4800 crane for the time period specified in the contract.
65 Mr Wilmott submitted, further, that the facsimile of 24 March 1997 should be construed as meaning that the respondent was intending only to supply a CC2600. I have come to a different conclusion on this issue when considering the repudiation ground and have expressed the view that the facsimile does not have that meaning. In my opinion, the facsimile of 24 March casts no reliable light on the likelihood of Van Seumeren supplying an "equivalent" crane by 14 July 1997. At the very least, as I have noted, the facsimile is ambiguous.
66 I return therefore to the Van Seumeren letter of 20 March 1997. Importantly, the letter does not contain a refusal by Van Seumeren to supply a CC4800 crane; rather, it is a refusal to provide an unconditional guarantee to supply a CC4800.
67 Secondly, the letter makes no reference to Van Seumeren's willingness or ability to supply an equivalent crane. Nevertheless, in this regard, the reference to the "verbal contract" with the respondent to provide an MDC3500 crane is ambiguous. Did Van Seumeren thereby intend to convey merely that it was able to supply an MDC3500 or did it mean that the only other suitable crane that it had available was an MDC3500? This is not at all clear.
68 The reference to a "verbal contract" may also be significant as, if there was a binding contract between the respondent and Van Seumeren to supply an MDC3500, it would be strong evidence that the respondent only intended to provide an MDC 3500 (on the basis that it believed - wrongly, as Windeyer J held - that it was an equivalent crane).
69 Van Seumeren, in its letter of 27 March 1997 to the respondent, stated that, as the contract between the appellant and the respondent had been terminated, "any agreement between Van Seumeren and [the respondent] for supply of the crane must also be regarded as terminated." This phraseology is not suggestive of a firm belief on the part of Van Seumeren that there was any binding contract between it and the respondent.
70 When Mr Bradbury was cross-examined, he testified, in effect, that he intended, once a formal agreement was entered into between the appellant and the respondent, to give Van Seumeren a formal order for the crane to be supplied by it. It was then put to him by counsel for the appellant that he did not "formalise" his order to Van Seumeren and he accepted that he had not done so (black book 168).
71 Later, in cross-examination, it was put to Mr Bradbury that he had no firm promise from Van Seumeren relating to a CC2600 crane and he replied that the respondent had received a "quotation" for a CC2600 (black book 170). In re-examination, as I have previously mentioned, he said that he had received a tender offer from Van Seumeren to supply a CC2600 (black book 172).
72 On the basis of the evidence to which I have referred, I am not persuaded that there was an agreement between Van Seumeren and the respondent concerning the supply either of an MDC3500 or a CC2600 crane.
73 Returning to the letter of 20 March 1997, in the circumstances I do not think that any inference can be drawn from it as to Van Seumeren's willingness (and ability) or otherwise to supply an equivalent crane to the respondent.
74 In all the circumstances, in my opinion, the Van Seumeren letter and the other evidence on which the appellant relied does not establish - as a matter of fact and not supposition - that, as at 25 March, the respondent was wholly and finally disabled from obtaining a CC4800 crane or its equivalent. I am not persuaded Windeyer J was incorrect when he found that there was a possibility that at 25 March the respondent would have been able to prevail upon Van Seumeren to provide an equivalent crane.
75 I agree, further, with Windeyer J that once such a possibility existed, there was a possibility that Van Seumeren would give the respondent within a reasonable time the requisite guarantee concerning the provision of such a crane.
