20 The appeal against the Determination Decision went largely to the use to be made of the evidence of the consultant psychiatrists, particularly the two called on behalf of the Practitioner, Professor Goldney and Dr McCarthy. The evidence of these two, as well as Professor Mullen, it was submitted, showed or at least pointed to a "respectable body of medical opinion" supporting the Practitioner's use of the TOMM test in ways of concern to the Board. This use, so supported, was said to be "a practice accepted at the time as proper by a responsible body of medical opinion even though other doctors adopted a different practice" which, thus, could not be characterised as conduct improper in a professional respect for the purposes of s 13(3) of the Act: Ipp J in Cranley v Medical Board of Western Australia, unreported; SCt of WA (Ipp J); Library No 8668; 21 December 1990, at 8. On this submission, it was not telling for this purpose that the three experts referred to had not themselves employed the TOMM test in their clinical practices, or at all. Nor was it telling, it was submitted, that the test was not in general use in Australia by other consultant forensic psychiatrists. (I note that there was a reference in the Practitioner's evidence before the Inquiry to two named psychiatrists in Perth whom he believed had begun to use the TOMM after he had presented on his use of it to colleagues, presentations to which I will return; he was not, however, sure whether or not they were using it as he did: transcript P-166.) Nor was it telling, it was submitted, that the Manual accompanying the test did not clearly allow for the form of use the Practitioner employed (although it was argued strenuously that the Manual, closely read, was capable of covering that sort of use). And it was not telling, it was further submitted, that the Manual did not clearly support the use of the TOMM as a means of determining overall veracity (although it was strenuously contended that, closely read, the Manual did allow for such use, as part of an overall clinical determination that drew in other probative material emerging from the clinical examination).
