First, the trial judge was invited to discount the appellant's oral testimony on the basis of accounts given to various health professionals, which appeared inconsistent either with each other, or with her oral testimony, or both. The difficulties attending this kind of exercise should be well-understood; as explained in the Container Terminals Australia Ltd v Huseyin [2008] NSWCA 320 at [8]. Such apparent inconsistencies may, and often should, be approached with caution for the following reasons, amongst others:
(a) the health professional who took the history has not been cross-examined about:
- the circumstances of the consultation;
- the manner in which the history was obtained;
- the period of time devoted to that exercise, and
- the accuracy of the recording;
(b) the fact that the history was probably taken in furtherance of a purpose which differed from the forensic exercise in the course of which it was being deployed in the proceedings;
(c) the record did not identify any questions which may have elucidated replies;
(d) the record is likely to be a summary prepared by a health professional, rather than a verbatim recording; and
(e) a range of factors, including fluency in English, the professional's knowledge of background circumstances of the incident and the patient's understanding of the purpose of the question, which will each affect the content of the history.
The fact that, in the present case, none of the health professionals was called to give oral evidence as to the matters in issue may not itself be a point of significance. It is unlikely that cross-examination would have advanced any issue in dispute; the witness being likely to have no relevant recollection of taking the history, the oral testimony would be largely limited to an assertion of usual practice.
Thirdly, and more significantly, it was quite possible that the elements of florid expression and exaggeration in the applicant's oral testimony (and in some of the recorded histories) may have been a function of her psychological state. This was not something that the trial judge could readily assess without expert assistance, but it was a possibility that should not have been ignored. On one view, the pre-attack records (particularly the notes of Dr Hamad) were devoid of the flamboyant language found in post-attack accounts.
