27 The scheme for appointment of persons as inspectors under the OHS Act with authority to prosecute for contravention of that Act in relation to coal workplaces is that the person must be one appointed as a government official under s 145 of the CMH&S Act. That Act empowers the Minister to appoint a person employed under Ch 2 of the PSE&M Act as, inter alia, an investigator. Where a person is appointed as an investigator under s 145 of the CMH&S Act the person is, according to s 47B of the OHS Act, taken to have been appointed as an inspector for the purposes of the OHS Act and the regulations under that Act, but such a person is only authorised to exercise functions under that Act in relation to a coal workplace, although they may exercise functions under Div 2 in relation to premises other than a coal workplace for the purpose of investigating any matter under the OHS Act in relation to a coal workplace. One of the functions of an inspector under the OHS Act is the prosecutorial function: s 106.
28 The focus of the defendant's attack on Mr Morrison's authority to prosecute lies in the contention that Mr Morrison was not a person employed under Ch 2 of the PSE&M Act and, therefore, the Minister (or the Minister's delegate) was not empowered to appoint Mr Morrison as an investigator, as purported to have been done in the application for order in this matter pursuant to s 246(1) of the Criminal Procedure Act. In the absence of being so employed, it was submitted, Mr Morrison could not be taken to have been appointed as an inspector for the purpose of s 47B of the OHS Act and, therefore, had no authority to prosecute, as he did not meet the requirements in s 106(1)(a), (b), (c) or (d).
29 The defendant's argument was that an employee can only be employed 'under' Ch 2 if he or she is 'subject to, bound or constrained by those provisions'. However, as the defendant submitted, by s 17(3) of the PSE&M Act, which is in Ch 2, the employment of senior executive officers in the Public Service was at the relevant time expressly made 'subject to' Pt 3.1 of the PSE&M Act. Section 69(1), which is in Pt 3.1, provides that the employment of an executive officer 'is to be governed by a contract of employment' between the officer and his or her employer. Accordingly, it was submitted, the words 'is to be governed' denoted that the authority of the contract over Mr Morrison's employment was absolute and exclusive and that there was no room for Mr Morrison to be also 'employed under' Ch 2.
30 As noted earlier, s 7(1)(a), in Ch 2 of the PSE&M Act, provides that:
(1) Staff may be employed in a Department in the following categories:
(a) officers - being persons employed in chief or senior executive positions or other staff positions in the Department,
…
31 The defendant accepted that it may be inferred that Mr Morrison was employed as a senior executive officer. Section 65(1)(a) of the PSE&M Act provides that the Senior Executive Service comprises, inter alia, 'persons holding positions for the time being determined by the Minister to be senior executive positions, being positions in the Government Service…'
32 Section 3 of the PSE&M Act provides that 'Government Service means the Government Service of New South Wales referred to in section 4A'. Section 4A(1), which is in Ch 1A, provides that:
The Government Service of New South Wales consists of those persons who are employed under this Chapter by the Government of New South Wales in the service of the Crown.
33 Section 4K(1)(d) in Ch 1A provides that 'In any other Act … a reference to the employment of a person under Chapter 2 of this Act is taken to include a reference to the employment of the person under Chapter 1A of this Act'.
34 Section 4B(1) in Ch 1A provides that 'The Government of New South Wales may … employ staff in any Division of the Government Service'. Section 4C provides that the Divisions of the Government Service are the Divisions specified in Schedule 1. At the relevant time, the Department of Primary Industries was specified as a Division of the Government Service.
35 Section 6 in Ch 2 provides:
(1) The Divisions of the Government Service specified in Part 1 of Schedule 1 comprise the Public Service of New South Wales.
(2) Any such Division may be referred to as a Department (or a Department of the Public Service ) for the purposes of this or any other Act….
…
36 In other words, Mr Morrison was a person holding a position in the Senior Executive Service, which is a position in the Government Service. The Government Service consists of persons employed under Ch 1A. According to s 4K, in any other Act (which must include the CMH&S Act) where reference is made to a person employed under Ch 2, that is taken to include reference to a person employed under Ch 1A. Chapter 1A (s 4B(1)) provides that staff may be employed in any Division of the Government Service. The Department of Primary Industries, in which Mr Morrison was employed, was at the relevant time a Division of the Government Service, which could be referred to as 'a Department': s 6(2). Section 7(1)(a), which is found in Ch 2 of the PSE&M Act, provides that staff may be employed in a Department and staff includes officers, which in turn includes persons employed in senior executive positions.
37 I take the view that the general power to employ staff in a Department is to be found in Ch 1A of the PSE&M Act. By virtue of s 4K, where reference is made to a person employed under Ch 2, that is taken to include reference to a person employed under Ch 1A. Section 7 of the PSE&M Act then defines the categories of staff who may be employed and they include senior executive officers.
38 Part 2.3 of the PSE&M Act deals with appointments as distinct from employment (see s 16) and provides how appointments of officers, other than Department Heads, in a Department are to be made. Section 17, which is found in Pt 2.3, is not, in my view, a source of power regarding employment. In other words, it does not displace the general employment power in Ch 1A by substituting Pt 3.1 of the Act in respect of senior executive officers.
39 Section 17 provides that the employment of a senior executive officer is 'subject to' Pt 3.1. I construe that to mean the employment is 'dependent or conditional upon' the provisions of Pt 3.1. In other words, one does not look to Pt 3.1 to discern whether the officer is employed under the PSE&M Act. That is done by ss 4A and 4B, and s 17 operates on that footing. What s 17 then does is to refer one to Pt 3.1 in order to find the conditions that attach to the employment.
