Subsections (3)-(6) of s 75 provide:
"(3) If:
(a) the appropriate Department Head, in the exercise of powers conferred by this section, decides to direct an officer to resign, or be allowed to resign, from the Public Service within a period specified in the direction, and
(b) the officer does not resign within that period,
the Department Head may decide to dismiss the officer from the Public Service.
(4) A decision of a Department Head under subsection (1) or (3) may be implemented at any time, but a decision of a Department Head under subsection (1)(d) or (e) or subsection (3) to dismiss an officer form the Public Service or to annul an officer's appointment must not be implemented without the approval of the Governor.
(5) Subsection (4) is subject to Part 3 of the Government and Related Employees Appeal Tribunal Act 1980 .
(6) If a Department Head decides to dismiss an officer from the Public Service in accordance with subsection (1)(d) or (3), the decision shall be treated as a decision of the kind referred to in section 23(1)(f) of the Government and Related Employees Appeal Tribunal Act 1980 even though the decision has not been approved by the Governor."
Submissions On Decision to Recommend Dismissal: The Appellant's Arguments
24 The appellant's arguments on the first part of the appeal fell into six groups. He put them substantially, though not precisely, in accordance with the following structure.
25 First, he submitted that the Tribunal addressed the wrong question. The decision against which the appeal to the Tribunal was brought was not a decision to dismiss the appellant. Rather it was the Acting Commissioner's decision, communicated by the letter of 3 November 1999.
26 Secondly, the appellant pointed out that the 3 November 1999 letter said: "I … have decided to recommend to the Governor … that you be dismissed". Section 24(1) permits an employee to "appeal to the Tribunal against a decision of his or her employer, being a decision of a kind referred to in section 23(1)". One of the decisions referred to in s 23(1) is a "decision to make a recommendation … to dismiss the employee". The decision to make the recommendation communicated in the 3 November 1999 letter, the appellant submitted, was plainly within that language.
27 Thirdly, the appellant submitted that so far as it is necessary that the decision appealed from be of a disciplinary nature, as is suggested by Director-General of the Department of Corrective Services v Mitchelson (1992) 26 NSWLR 648, especially at 656A-C, 663A and 664D-665A, it was. On 12 May 1999 the appellant was notified that he was charged with two breaches of discipline, and that he was suspended. The letter of 11 October 1999 informed the appellant that he had made seven admissions to the Independent Commission Against Corruption and invited him to show cause why the Commissioner should not recommend dismissal to the Governor. The first admission appeared to have the same subject-matter as the first charge, and the second admission appeared to have the same subject-matter as the second charge. The 11 October 1999 letter also informed the appellant that the suspension from duty notified on 12 May 1999 would continue. After representations made on the appellant's behalf had been considered, the decision complained of was made. The appellant submitted that: "The inevitable conclusion is that the decision to recommend dismissal was a direct disciplinary response to the admissions of misconduct said to have been made by the Appellant to the ICAC" (written submissions paragraph 9.4).
28 Fourthly, the appellant submitted that no issue arose as to whether there was any collision between, on the one hand, the existence of an appeal under s 24(1) against a s 23(1) decision to recommend a dismissal and, on the other hand, the Crown's common law prerogative right to dismiss at pleasure. This was because the appeal to the Tribunal was not brought from the Governor's decision to dismiss on 25 November 1999, but from the Acting Commissioner's decision to recommend dismissal communicated on 3 November 1999.
29 Fifthly, the appellant submitted that if his appeal against the Acting Commissioner's decision to recommend dismissal involved an interference with the Crown's common law prerogative right to dismiss at pleasure, the interference was lawful as being authorised by ss23(1) and 24(1). In writing he submitted:
"10.1 It is well established that the Crown's prerogative to dismiss its employees at pleasure can be restricted or abolished by statute (see, for example, Gould v Stewart [1896] AC 575; Director-General of Education v Suttling (1987) 162 CLR 427 at 442 per Brennan J, Mason ACJ and Deane J assenting; Bennett v Commonwealth (1980) 44 FLR 446; Coutts v The Commonwealth (1985) 157 CLR 91 at 103 per Wilson J; Barratt v Howard (1999) 165 ALR 605 at 608-9.
10.2 Not every statutory right of appeal from a dismissal of a public sector employee will interfere with the exercise of the Crown prerogative. However, an appeal from a decision to recommend dismissal, as here - if it involves an interference with the Crown prerogative - is to that extent expressly authorised by the statute. The prerogative is modified accordingly.
10.3 The decisions upon which the Tribunal relied generally concerned whether, on their proper construction, specific statutory provisions had the effect of restricting or ousting the common law Crown prerogative. They are not authority that the provisions of the GREAT Act are incapable of ousting the prerogative. For example, in Fletcher v Nott (1938) 60 CLR 55 and Kaye v Attorney General for Tasmania (1956) 94 CLR 193, the statutory appeal provisions relied upon only allowed for appeals by police officers from decisions of the Commissioner of Police, not from the Governor in Council. Those decisions are distinguishable because the GREAT Act allows in terms for appeals from decisions recommending dismissal by 'employers', a term defined in s.4 to include the Commissioner."
30 Sixthly, the appellant submitted that the provisions in the PSM Act relied on by the Tribunal and by the first respondent did not have the effect contended for. In particular, s 54 of the PSM Act did not prevent s 24(1) of the GREAT Act from modifying the common law Crown prerogative right, for three reasons. First, the opening words of s 24(1) of the GREAT Act, enacted in 1980, were "Notwithstanding anything contained in any other Act"; those words applied to other Acts enacted after 1980 as well as before; and they meant that s 24(1) had whatever effect it had notwithstanding s 54. Secondly, s 54 in terms did not apply to the GREAT Act; it provided that the Crown's common law right as it existed immediately before the PSM Act was enacted in 1988 was not restricted or abrogated "by any of the provisions of this Act", i.e. the PSM Act as distinct from the GREAT Act. Thirdly, the preservation of the prerogative effected by s 54 effected only a preservation of the right "as it existed immediately before the commencement of" s 54 in 1988, and by that date the GREAT Act had been in force for eight years.
