Mr Niall, who appeared as counsel for Mr Singh, contended that the procedure relevant to this case was to be found in s 427(1)(d) of the Act, which provides that the Tribunal may:
"require the Secretary to arrange for the making of any investigation, or any medical examination, that the Tribunal thinks necessary with respect to the review, and to give to the Tribunal a report of that investigation or examination".
He contended that the section required the Tribunal to consider whether to have the Secretary to the Department arrange for a psychological or psychiatric examination of Mr Singh. As the Tribunal had not considered the question, it had failed to observe a procedure required by the Act.
The alleged requirement to consider the issue is not expressly stated. The contention is that it is implicit in the section. I doubt that s 476(1)(a) relates to matters which are not expressly stated in the Act. Examples of requirements which are expressly stated are the requirement that the Tribunal give the applicant an opportunity to appear and give evidence (s 425(1)(a)), the requirement that the Tribunal notify the applicant of an entitlement to appear and give evidence before the Tribunal (s 426(1)(a)), and the requirement that the Tribunal give written reasons (s 430). In my view, there is no implicit requirement in s 427(1)(d) that the Tribunal consider whether to have the Secretary arrange a medical examination. The section is permissive. It gives the Tribunal a power. The Act does not require that the power be exercised, and it follows that it does not require the Tribunal to consider whether it should be exercised. Thus, although a failure to consider whether to exercise the power may be unwise in certain circumstances, it is not a failure to observe a procedure required to be observed by the Act.
One difficulty with the notion of an implicit requirement is the problem of identifying the scope of the alleged requirement. Parliament cannot have intended that the Tribunal must consider exercising a power in circumstances where it would be totally irrelevant to the particular case before the Tribunal. For instance, in a case involving no medical question, there could be no requirement that the Tribunal consider whether to use the power to have a medical examination arranged. There would be no review available under s 476(1)(a) if the Tribunal failed to consider having the Secretary arrange a medical examination in such a case. Thus, the alleged implicit requirement to consider the use of the power must be limited to cases which raise an issue to which a medical examination would be relevant. See Dharam Raj v Minister for Immigration & Ethnic Affairs and Another (unreported, Federal Court of Australia, Davies J, 18 July 1996, at 4). Even if, contrary to my view, there was an implicit requirement that the Tribunal consider whether to exercise the power under s 427(1)(d), the present case did not raise an issue to which a medical examination would be relevant.
Mr Niall referred to the following exchange between the Tribunal and Mr Singh as giving rise to the Tribunal's obligation to consider the need for a medical examination:
"MR ENDREY: And how long did you spend in Bombay again before you found work once more?
THE INTERPRETER: I didn't stay in Bombay that time I went back to Punjab. In Punjab the situation was not good and I was tortured at that time in Punjab. Sorry, I was tortured in Bombay.
MR ENDREY: What was the basis of the torture? What was the reason for it?
