Inferences from failure to call Ms Mulvihill and third defendant's husband
74Evidence was not called from two people who might have been able to given important evidence in relation to the signature, namely Ms Muvihill and the third defendant's husband. The plaintiff invited me to draw an adverse inference against the first defendant because of their failure to call those witnesses.
75The failure to call Ms Mulvihill, who was a witness to the signature on the mortgage was an important matter. As I have said, she was a person who worked for, or with, the third defendant's husband and appears to be a Justice of the Peace. It is plain that she could give evidence of the signature on the documents. Neither party gave any evidence as to her whereabouts but an email from her is in evidence.
76The plaintiff submitted that I should draw a Jones v Dunkel inference against the first defendant for its failure to call Mr Mulvihill. The so-called rule in Jones v Dunkel (1958) 101 CLR 298 permits the Court to draw an inference that the uncalled evidence would not have assisted the party who failed to call it and entitle the trier of fact to more readily draw any inference fairly to be drawn from other evidence: "Cross on Evidence" (Aus ed), at [1215]; Romeo v Papalia [2012] NSWCA 221 at [121]. However the failure to call the witness cannot be used to fill gaps in the evidence: Romeo v Papalia.
77Strictly speaking, as Hodgson JA (with whom Beazley JA agreed) pointed out in Ho v Powell [2001] NSWCA 168, Jones v Dunkel related to a situation where there was evidence supporting an inference against a party, and that party did not give or call evidence, which that party was plainly in a position to have given or called, in order to explain or contradict the material presented. His Honour said that in his opinion, a similar principle applies where a person bearing the onus of proof does not give or call evidence which that person is plainly in a position to give or call; and unless some explanation is given of this failure, the tribunal of fact is entitled to infer that this evidence would not have assisted that person's case (at [15] - [16]).
78The rule is a specific application of the well-established principles that a party is expected, within reasonable limits, to produce at the trial all the evidence that is fairly available to him: Spence v Demasi (1988) 8 MVR 1 at 12. The principle does not extend to drawing an inference that the uncalled evidence would in fact have been damaging to the party not calling it: Moore v Moore [2012] FAMCA 387 per Strickland J at [84]. Similarly, in civil cases, the unexplained failure of a party to call witnesses is not treated as evidence of fear that it would expose an unfavourable fact, nor as an assertion of the non-existence of the fact not proved: HML v R [2008] HCA 16; Fazio v Fazio [2012] WASCA 72.
79In relation to Ms Mulvihill and the third defendant's husband, the first question, in my view is: which party is expected to call her or him? The cases deal with this by asking: to which party is the witness available, or what "camp" is the witness in? See for example Commonwealth Bank of Australia v Munro [2011] NSWSC 128 at [44]; Payne v Parker (1976) 1 NSWLR 191 per Glass JA. The second question is whether the witness' evidence would elucidate a particular matter. The final question is whether that party could be fairly expected to call Ms Mulvihill or the third defendant's husband, or whether there is a reason that properly explains their absence, other than that the witness would not assist that party's case.
80Cox J summarised these questions in relation to a supporting witness (as opposed to a party not giving evidence) in Spence v Demasi, as follows:
"So far as a potential supporting witness is concerned, the court will first have to decide whether his absence should be regarded as telling against one party rather than the other - whether, in the nature of things, he should be put in a particular camp or simply seen as available equally to both sides. Even where that test is satisfied, an adverse inference cannot be drawn if there is an obvious or proved, and satisfactory, explanation for the failure to call the witness. That will depend upon the facts of the particular case."
81In relation to the first matter, the significance of the inference depends on the closeness of the relationship of the absent witness with the party who did not call the witness: "Cross on Evidence" at [1215]; Hospitality Group Pty Ltd v Australian Rugby Union Ltd [2001] FCA 1040; Dilose v Latec Finance Pty Ltd (1966) 84 WN (Pt1)(NSW) 557 at 582.
82Once it is established that a witness is available to one of the parties, the tribunal of fact must be satisfied that he probably would have the relevant knowledge or there would be no basis for any adverse deduction from the failure to call the witness: Payne v Parker.
83Finally, it is necessary to verify that the potential witness not only could shed light on the subject in dispute, but also would ordinarily be expected to do so: RPS v R [2000] HCA 3. In relation to reasons why a party might choose not to call a witness, without attracting a negative inference against them despite the witness being in their "camp" and being able to elucidate a matter, Bray CJ said in Smith v Samuels [1976] 12 SASR 573:
"For the unfavourable inference to be justified the witness not called must be available: it must be 'in the power' of the party to call him. He may be unavailable through absence or illness. He may be unavailable because he would not be a competent witness. In my view he may also be unavailable in the relevant sense, or at least no unfavourable inference should be drawn from his absence, when there are strong reasons for not calling him other than the falsehood of the story he might be expected to confirm, such as his hostility to the party or, I would say, jeopardy or grave prejudice to the witness himself...." (emphasis added)
84In this case there has been evidence adduced supporting the plaintiff's case that the third defendant did not sign the mortgage to the first defendant, namely the third defendant's evidence and the expert report. The first defendant could have called Ms Mulvihill to contradict that evidence. Plainly she would be the person with knowledge of who executed the mortgage. However, the first defendant has not called Ms Mulvihill and no explanation has been given as to why she was not called. Therefore, in my view, I am entitled to draw the inference that her evidence would not have assisted the first defendant's case.
85The plaintiff also drew to my attention the fact that the third defendant's husband was not called.
86The third defendant did not in her evidence in chief suggest who might have forged the documents. Similarly, the first defendant did not cross-examine the third defendant as to whom she believes forged her signature. Given that the mortgage documents were handed by the solicitors to the third defendant's husband, who took them away and returned them signed, and who also benefited from the loan secured by the mortgage, he could have been called to give helpful evidence. However, I do not think that the third defendant's husband can be said to be in the "camp" of either the plaintiff or the first defendant such that I might draw an adverse inference against either party for not calling him. While clearly he has a very close relationship with his wife, the third defendant, that does not translate in this case to having a close relationship with the first defendant, given that the third defendant and the first defendant maintain opposing versions of events.
87He is also not available to the parties in the relevant sense given that what he might say in evidence could be unknown to them. I would not expect a party to call the husband "blind" in the hope of bolstering their case. Most importantly, a Jones v Dunkel inference may not arise if a witness has a reason for not telling the truth or refusing to assist and the party who may call the witness is aware of this: Fabre v Arenales (1992) 27 NSWLR 437. In Fabre, Mahoney JA (with whom Priestley and Sheller JJA agreed) said at 449-450:
"The significance to be attributed to the fact that a witness did not give evidence will in the end depend upon whether, in the circumstances, it is to be inferred that the reason why the witness was not called was because the party expected to call him feared to do so. But there are circumstances in which it has been recognised that such an inference is not available or, if available, is of little significance. The party may not be in a position to call the witness. He may not be sufficiently aware of what the witness would say to warrant the inference that, in the relevant sense, he feared to call him. The reason why the witness is not called may have no relevant relationship to the fact in issue: it may be related to, for example, the fact that the party simply does not know what the witness will say. A party is not, under pain of a detrimental inference, required to call a witness 'blind'." (emphasis added)
88Neither party would know what the third defendant's husband would say about signing the mortgage and they would be calling him blind. If his evidence was to be that he forged the signatures he would claim privilege under s 128 of the Evidence Act and the court might not require him to answer questions on that topic under s 128(4). I do not draw an inference against either party for their failure to call the third defendant's husband.
