6 The primary judge heard the case over seven days. He heard oral evidence from Mr So, Mr Su and others, but not Mr Cuoco who did not give evidence. His Honour described the evidence of each of Mr So and Mr Su in unflattering terms. He said (at [12] of his reasons) that he was "strongly of the view that at times they each gave evidence that so defied credulity that it was almost an insult to the court to imagine that it might be accepted." His Honour refused (at [14] of his reasons) to place any weight at all on the demeanour of the plaintiff (Mr So) and of the first defendant (Mr Su). His Honour said (at [14] of his reasons) that the only way to resolve the dispute was to look for matters within the whole of the evidence which tended to favour one side or the other.
7 The primary judge also referred (at [19] of his reasons) to the evidence of other witnesses. He did so after listing, at length, the factors which bore for and against the acceptance of the respective versions of the plaintiff (Mr So) and the first defendant (Mr Su). His Honour said:
"… It will be noticed that I have not referred to the many conversations asserted by or on behalf of the plaintiff and first defendant which took place in assorted motor vehicles, restaurants and a gambling establishment. The reason I have not factored these conversations into the equation is that, without more, on my assessment of the witnesses I would simply not be in a position to accept the versions of one or the other. Whether or not these conversations occurred must depend on whether or not they are consistent with my findings based on the above factors. It may even be the case that the actual conversations, if they occurred, are not as alleged by either party."
8 The primary judge was faced with oral evidence from all sides which he profoundly distrusted. Yet, as his Honour said at [7] of his reasons:
"… an acceptance of either the plaintiff's version or the first defendant's (including that of his witnesses) is vital to the outcome of the case. Credit, therefore, plays a major part in the decision."
9 At [14] and [15] the primary judge described his dilemma, given the apparent unreliability of the oral evidence:
"[14] The parties, if I understood them correctly, agreed with my observation that the outcome of the case depended on the acceptance on the evidence of one of the plaintiff or the first defendant (including his witnesses). I have already said that the demeanour of the plaintiff and the first defendant has no effect on my decision as to their reliability. Further, both of them, as I have highlighted above, put matters to the court which were simply beyond belief. I think the only way to resolve this dispute is to look for matters within the whole of the evidence which tend to favour one side or the other.
[15] I think the appropriate way to conduct this exercise is to look at matters which favour the plaintiff's case and those which are against it. In doing so I am also, in effect, looking at issues which favour, or do not favour, the first defendant's case. It is worth recalling at this stage that the plaintiff's allegation is that the property at 3 Rose Parade was purchased for his sole benefit as a means of assisting him to recoup the moneys (about $825,000) that he says he lent to SDL [Suprising Development Pty Ltd, a company of which Mr So, Mr Su and two others were directors]."
(emphasis added)
10 As we read these paragraphs, his Honour set about looking for objectively verifiable factors to permit him to reach his decision. Such a course may be seen to remove the trial judge's advantage of assessment of credit and demeanour and placing the appeal court in a position of being able to review the findings, subject only to the recognition of the more general and less potent advantage of a trial judge of absorbing, integrating and synthesising facts over the course of a trial: State Rail Authority (NSW) v Earthline Constructions Pty Ltd [1999] HCA 3; 73 ALJR 306 at 330 [90]; and Fox v Percy [2003] HCA 22; 214 CLR 118 at 125-126 [23] esp. footnotes 34 and 35. There was a debate as to whether, in fact, the learned primary judge did employ demeanour so as to require this Court to conclude that the primary judge had misused his position or that his findings were glaringly improbable or contrary to incontrovertible facts in the sense discussed in Fox v Percy at 127-129 [26]-[31] and Abalos v Australian Postal Commission [1990] HCA 47; 171 CLR 167 at 179. We will return to this question of appellate review in due course.
11 It is instructive, to set out the starkly contradictory cases of the parties as clearly summarised by the learned primary judge at [3], [4] and [5] of his reasons:
"[3] According to the plaintiff:
(a) The first defendant, or one of his companies, owed him approximately $825,000.
(b) The property was purchased in his name as a means of appeasing him for the failure to repay the debt.
(c) He was free to sell the property at his will and to retain any profit on the sale.
(d) It was for him to decide whether it would be renovated or sold.
(e) He was not aware that the property was sold in December 2004. He certainly did not authorise it.
(f) He did not find out about the sale of the property until October 2006.
(g) He was never told that renovations were to be carried out on the property and he did not know they had been effected.
(h) The first defendant fraudulently effected the sale knowing it was not his to sell.
(i) The second defendant, in effect, conspired in the fraud because it knew, or should have known, that the sale was not authorised by the property's owner, the plaintiff.
(j) As a result of the fraudulent sale the plaintiff says he is entitled to the profit (of $107,000) ostensibly made on the sale. In addition, he wants exemplary damages from both defendants.
[4] The first defendant paints a very different picture. According to him:
(a) The plaintiff, together with the second defendant and two others, were directors of a company called Suprising Pty Limited ("SDL").
(b) The property was bought on behalf of this company.
(c) The plaintiff's name was used on the purchase for taxation reasons.
(d) The plaintiff authorised the first defendant to sell the property.
(e) The plaintiff knew about the sale and consented to it happening.
[5] In addition the first defendant has a 'back up' case which asserts a constructive trust on behalf of SDL in case the plaintiff's version is accepted. This Resulting Trust stems from the renovation work carried out on the property."
12 In [16] and [17] of his reasons, the primary judge set out the matters which favoured the plaintiff's and the first defendant's respective versions. In summary these matters were:
