68 The statement of Mason J in argument in Brayson was referred to with approval by the Full Court of the Federal Court in Flanagan v Commissioner of Australian Federal Police[11].
69 In my view, the fact that the relevant regulation was made at the time of inclusion in the Act of s. 79I does mean that the Court can look at the regulation when considering the overall scheme of the appeal rights granted by the Act. However, as I have said, reg. 29(4) is equivocal, in the sense that it is consistent with both forms of appeal under consideration. Further, reg. 29(5) is consistent with both forms of appeal. In my view, the Regulations are, on any view, not decisive of the issue which I must determine as to the nature of the appeal granted under s. 79I of the Act.
70 In my opinion, it is also relevant to the construction of s. 79I of the Act to consider the nature of the decision which is the subject of appeal. In this regard, it is relevant that s. 79I provides for both disciplinary appeals and promotion appeals. Each of these may involve very serious consequences for the appellant. The most serious of these is demonstrated by this case. The applicant's employment is at risk. A decision to dismiss an employee constitutes "a deprivation of a valuable privilege" such that Parliament may be taken to have intended to confer a right to a de novo appeal[12].
71 A final matter which I think is highly relevant to the interpretation of s. 79I is the fact that it provides for both disciplinary appeals and promotion appeals. Promotion appeals are from decisions made by the Board under s. 25B(1)(e) of the Act. Apart from the Regulations, which specify notification requirements for applications for promotion and of promotions, there is no procedure specified in the Act. The standard to be applied in dealing with promotions of operational staff is also contained in the Regulations[13].
72 Under s. 9 of the Act, the Board is comprised of up to seven members appointed by the Governor-in-Council. The functions of the Board are stated in s. 7 of the Act. Having regard to the broad ranging nature of these functions, promotion matters are likely to occupy a very small amount of the time of the Board. It is in my view extremely unlikely that a body such as the Board was intended to conduct a hearing in relation to promotion matters. There is no requirement in the Act for the Board to conduct such a hearing. Nor is there any requirement in the Act for the Board to keep a record of its deliberations on a promotion application or to provide reasons for its decision. Accordingly, it is likely that a promotion appeal under s. 79I will be the first and only opportunity which an aggrieved employee may have to test the factual basis on which his or her application for promotion was determined. In these circumstances, I am of the opinion that Parliament intended to grant a de novo appeal to a person aggrieved by a decision to refuse his or her application for a promotion.
73 In this regard, I note that it was argued on behalf of the defendant that an appeal under s. 79I may be of a different nature depending on whether it was a disciplinary appeal or a promotional appeal. I reject this submission. In my view it is inconsistent with the decision in Coal and Allied[14].
74 For the above reasons, I am of the view that Parliament intended to grant an appellant under s. 79I a right to a de novo appeal. That was not done in this case. What is the consequence of this? In my opinion, by hearing and determining the appeal as a re-hearing appeal, the Commission fell into jurisdictional error by misapprehending the nature of its function under s. 79I.
