The contravening conduct
10 In 2020, Sarah Constructions Pty Ltd (Sarah) was engaged by the City of Marion as the construction contractor in redevelopment works at the Morphettville Park Sports Club at Dunbar Avenue in Morphettville in South Australia (the Site). Mr Mark Cramp was Sarah's Project Manager at the Site.
11 Sarah had subcontracted cladding work to SA Construct Pty Ltd (SA Construct). It had engaged Mr Matthew Dezen to work at the Site as a cladder.
12 On 14 February 2020 at 12.10 pm, Mr Jackson and another CFMMEU organiser (Mr Savage) entered the Site. When doing so, they provided Mr Cramp with an entry notice under s 119 of the WHS Act, signed by Mr Jackson. The notice identified three suspected contraventions of the WHS Act:
(i) Edge protection;
(ii) Access and egress through site; and
(iii) Section 19 duty of care.
13 It is an agreed fact that Mr Jackson and Mr Savage had made observations before entering the Site which led them to suspect that Sarah had, in relation to "relevant workers" within the meaning of s 116 of the WHS Act, contravened, or was contravening, its obligations:
(1) under s 19(1) of the WHS Act to ensure, so far as reasonably practicable, the health and safety of workers engaged or caused to be engaged by it while those workers were at work on the Site;
(2) under s 19(3) of the WHS Act to ensure so far as reasonably practicable, the provision and maintenance of work environment without risks to health and safety and the provision and maintenance of safe systems of work;
(3) under s 40 of the WHS Regulations to, amongst other things, ensure so far as reasonably practicable that the layout of the Site allowed, and was maintained to allow, persons to enter and exit and move about without risks to health and safety under normal working conditions and in an emergency.
14 Mr Cramp permitted the entry of Mr Jackson and Mr Savage onto the Site and they signed the Visitors' Register as requested by him.
15 While inspecting some scaffolding, Mr Jackson had the following conversation with Mr Dezen:
Jackson: Who built this? This platform ladder is too high.
Dezen: What's the matter with the scaffold?
Jackson: You should know that. It's your job. If you don't, you're an idiot.
Dezen: That's not how you should speak to people.
Jackson: I'll speak to you however the fuck I want.
Dezen: I wouldn't want you representing me on site.
16 Mr Dezen then said words to the effect that Mr Savage was conducting himself appropriately and that Mr Jackson should behave in the same way. The conversation then continued:
Jackson: You keep going, you'll never work in South Australia again.
It is an agreed fact that, as Mr Jackson spoke these last words to Mr Dezen, he moved towards him.
17 Shortly afterwards, while inspecting the perimeter of a building at the Site, the following interchange occurred between Mr Jackson and Mr Cramp:
Jackson: What's your fucking role here? Who runs the show on this Site? The safety is bad.
Cramp: I'll look into all the things you've identified. You know you can catch more bees with honey than you do with vinegar.
18 It is an agreed fact that, during his respective interchanges with Mr Dezen and Mr Cramp, Mr Jackson had spoken in an aggressive fashion. However, it is also an agreed fact that, apart from the manner in which Mr Jackson had spoken to Mr Dezen and Mr Cramp, he and Mr Savage had conducted their enquiries into the suspected contraventions in an appropriate manner and without incident or complaint from representatives of Sarah or of SA Construct. In particular, it is an agreed fact that, throughout the entry on the Site, Mr Savage had behaved in a "professional [and] amicable" manner and as a "gentleman".
19 The Commissioner alleges, and the respondents accept, that Mr Jackson's conduct had been improper because, in addition to his aggression, he had been abusive (by calling Mr Dezen "an idiot", by telling Mr Dezen that he would speak to him "however the fuck I want" and by asking Mr Cramp "what's your fucking role here?").
20 The Commissioner also alleges, and the respondents accept, that Mr Jackson's conduct towards Mr Dezen had involved a threat to his future employment prospects ("you keep going, you'll never work in South Australia again") and that Mr Jackson had reinforced the threat by simultaneously moving towards Mr Dezen.
21 The Commissioner's claim in short is that Mr Jackson's conduct was improper because of his aggression, because of his abusive language and because of the threat which he had made to Mr Dezen. The Commissioner contends, and the respondents do not dispute, that by acting in this manner in the exercise of his statutory right to enter the premises, Mr Jackson had fallen below the standard of conduct to be expected of a person in his position by "reasonable persons with knowledge of the duties, powers and authority of the position and the circumstances of the case": R v Byrnes [1995] HCA 1; (1995) 183 CLR 501 at 514-5.
22 As noted at the commencement of these reasons, Mr Jackson admits that he had acted in an improper manner for the purposes of s 500 of the FW Act.
23 The CFMMEU admits that, by virtue of s 793(1) of the FW Act, it is to be taken to have engaged in the same conduct as did Mr Jackson and that, by virtue of s 793(2) it had the same state of mind as did Mr Jackson. The CFMMEU thereby acknowledges that it was "knowingly concerned", within the meaning of s 550(2)(c) of the FW Act, in Mr Jackson's contravention of s 500 and that, by s 550(1) of the FW Act, it is also taken to have contravened s 500.
