REASONS FOR JUDGMENT
LANDER J:
7 The respondent is a medical practitioner whose conduct was the subject of an inquiry by the first appellant sitting as the Professional Services Review Committee No. 297 (the Committee) under Part VAA of the Health Insurance Act 1973 (Cth) (the Act) and the Health Insurance (Professional Services Review) Regulations 1999 (the Regulations).
8 On 13 December 2001 the Health Insurance Commission (the third appellant) (the Commission) made an Investigative Referral No. 297 to the fourth appellant who was then the Acting Director, Professional Services Review under the Act.
9 This was the second investigative referral by the Commission. On 7 June 2001 the Commission had previously referred the respondent's conduct to the Director of Professional Services Review in Investigative Referral No. 254 in relation to the same referral period and the same services as those contained in Investigative Referral No. 297. Investigative Referral No. 254 did not particularise the conduct which was considered relevant to the investigation into whether the respondent engaged in inappropriate practice and, in those circumstances, the then Director decided to take no further action in respect of that referral.
10 The Acting Director of Professional Services Review conducted an inquiry, as he was obliged, under s 89 of the Act into the referred services in Investigative Referral No. 297.
11 The Acting Director determined that he should proceed under s 93(1) of the Act and on 14 February 2002 set up the Committee to consider whether the respondent's conduct in connection with rendering the specified services constituted engaging in inappropriate practice as defined under the Act.
12 On 15 November 2002 the Committee published its finding that:
'Dr Donald Frank Hatcher engaged in inappropriate practice by rendering 80 or more professional attendances on each of the 37 days, as this constituted a prescribed pattern of services under subsection 106KA(1) of the Act, and for the purposes of subsection 106KA(2) of the Act, it does not consider that exceptional circumstances existed that affected the rendering of services by Dr Hatcher on any of the 37 days in question.'
13 Because the Committee made a finding of inappropriate practice, s 106T of the Act was enlivened and the Determining Authority was bound to consider the Committee's finding in accordance with the procedure under that section and s 106TA, s 106U and s 106UA.
14 On 15 March 2003 the Determining Authority (the members of which were unanimous) made a final determination and, under s 106TA, made the following directions:
'3. Under section 106TA of the Act, the Determining Authority's [sic] directs that:
(i) Dr Hatcher be reprimanded by the Director, Professional Services Review, or the Director's nominee (paragraph 106U(1)(a) of the Act);
(ii) Dr Hatcher be counselled by the Director, Professional Services Review, or the Director's nominee (paragraph 106U(1)(b) of the Act);
(iii) Dr Hatcher repay to the Commonwealth, Medicare benefits in the amount of $67,796.75 (sub-paragraph 106U(1)(ca) of the Act); and
(iv) Dr Hatcher be fully disqualified for a period of 4 weeks from the time when the final determination takes effect (paragraph 106U(1)(h) of the Act).'
15 It published reasons for those directions.
16 The respondent sought a review of the decision of the Commission to make the Investigative Referral No. 297 to the Acting Director; the decision of the Committee's finding of inappropriate practice; and the decision of the Determining Authority to give the directions.
17 On 30 November 2004 the primary judge made the following orders:
'1. The directions of 15 May 2003 by the [Determining Authority] be set aside.
