Grounds 4 and 5: The evidence of Zeinab Mustapha
26 The appellant submits that the Tribunal capriciously and without giving proper reasons rejected the evidence of Zeinab Mustapha. Essentially she denied that the complainant, or anyone on her behalf, paid the appellant $325 in her presence or that the appellant issued a receipt. The Tribunal said that it did not accept the evidence of Zeinab Mustapha where it conflicted with that of the patient and her family. This finding followed closely on the Tribunal's rejection of the appellant's version of events. Zeinab's evidence was within a fairly narrow compass, particularly concerning the payment of $325 to the appellant. The evidence of the payment on the complainant's side was very persuasive. By contrast, Zeinab's evidence on the issue was confused, implausible and at times contradictory.
27 The Tribunal was entitled to reject the evidence of Zeinab when she said that no payment of $325 was made. The Tribunal did not need to refer to all of the evidence led or to indicate which evidence it accepted or rejected. As Samuels JA said in Mifsud v Campbell (1991) 21 NSWLR 728, the duty to give reasons depends upon the circumstances of the individual case. The Tribunal gave sufficient reasons. It did not act capriciously in rejecting Zeinab's evidence on the payment.
Ground 7: The evidence of Mr Hanna
28 In considering the appellant's explanation about the disputed receipt, the Tribunal said that it rejected his at times contradictory evidence about the purchase of a nebuliser on 12 February 1998 from Mr Hanna, a pharmacist in the same building as the appellant. The Tribunal rejected the appellant's evidence that the complainant's mother asked him to provide a nebuliser. The Tribunal preferred the mother's evidence that no such conversation took place. It was in this context that the Tribunal said:
There are a number of inconsistencies and contradictions in the evidence of both the practitioner and Mr. Hanna concerning this matter. Whilst the Tribunal accepts it is possible that both the practitioner and Mr. Hanna were victims of unfortunate flooding incidents at or about the same time, the practitioner's occurring in his surgery adjacent to Mr. Hanna's pharmacy, whilst Mr. Hanna's occurred in the garage of his home, the Tribunal does not accept that documents capable of supporting their versions of this transaction were thereby destroyed. The Tribunal is, however, satisfied that if the practitioner did purchase a nebuliser from Mr. Hanna, there was no discussion between himself and the patient's mother relating to this item. Nor does the Tribunal accept that the practitioner carried around in his wallet for a period of approximately three years, the receipt with which he says he was provided by Mr. Hanna as evidence of this transaction.
29 It is not clear from this statement that the Tribunal rejected Mr Hanna's evidence, although it is apparent that it had some doubts about it. To this extent the ground of appeal, which claims that the Tribunal erred in rejecting Mr Hanna's evidence, must be rejected. However, what is evident is that even if the Tribunal accepted the evidence of Mr Hanna that the appellant purchased a nebuliser from him on 12 February 1998 for $450, this did not necessarily assist the appellant's case.
30 The appellant's evidence about the disputed receipt of 6 May 1998 for $325 was open to rejection by the Tribunal on a number of substantial grounds quite unrelated to Mr Hanna's limited evidence. For example, the appellant's first response to the production of the receipt by the respondent was to deny it was his receipt. It was only upon being confronted with the opinion of handwriting experts that it was his document that the appellant acknowledged it was his document. He then moved to explain the document by reference to the nebuliser purchase for the complainant's mother obtained, he claimed, from Mr Hanna earlier in 1998.
31 Thus, even if Mr Hanna's evidence was given full weight, its assistance to the appellant would have been minimal. It would not have affected the Tribunal's findings about the appellant's conduct concerning the disputed receipt, findings which were patently open to the Tribunal.
Grounds 8 - 10: The circumstantial case
32 These group of grounds take issue with the way the Tribunal approached the complainant's 'circumstantial case'. Particular criticism was made of the Tribunal's finding that the only plausible explanation for the clinical findings of the patient's elevated testosterone was that the appellant had injected it into the girl over six weeks. This was claimed to be an error in relation to the legal burden of proof.
33 The submission made on behalf of the appellant on these grounds is premised on the basis of the need for the respondent to prove that the appellant actually supplied patient A with Andriol and injected her with Sustanon 250mg doses. It is contended that in finding that the appellant administered the treatment, the Tribunal must have misapplied the Briginshaw standard.
34 In particular, the appellant is critical of the following finding of the Tribunal:
The Tribunal is further comfortably satisfied that the only plausible explanation for the clinical findings and the elevated testosterone, is that the practitioner administered testosterone by injection during the six-week period of treatment.
35 It is suggested that the Tribunal's reasoning discloses a process more akin to one of elimination, thus depriving the practitioner of the benefit of the Briginshaw standard.
36 However, a fair reading of the Tribunal's decision makes it plain that it did not misdirect itself as to what needed to be established, see for example what it said at Red AB 91 O to U.
37 The case against Dr Gad may have been in essence a circumstantial one, however, it must be said that it was a very strong one. The complainant did not have access to testosterone. She quite clearly had been injected with it. A formidable array of evidence pointed to Dr Gad as the person who so injected her. On the evidence, it would not be difficult to also conclude that he supplied the girl with Andriol capsules. They were findings which were clearly open to be made on the Briginshaw standard, if not, in my view, beyond reasonable doubt.
38 The evidence of virilizing signs developing in the patient also provides corroboration of the case against Dr Gad.
39 It is also quite clear that the preparation was identified as testosterone. The medical evidence on this is beyond reasonable argument.
40 I can see no error in the Tribunal's approach. It was perfectly open to the Tribunal to conclude that there was no other explanation for the clinical findings and that the only plausible explanation was that the appellant had administered testosterone to the patient. This involved no breach of the Briginshaw standard. No reversal of the onus of proof or error in relation to the burden of proof is apparent.
Grounds 11 - 13: The patient's records
41 These grounds were added in a supplementary notice of grounds of appeal. They provide as follows:
11. The Tribunal erred in making a finding in its decision of 19 October 2001 that the Appellant had falsified the patient's records when no such allegation was made against him in the Complaint.
