A 'positive finding' versus the operation of the reverse onus
31 In its written submissions the University contends that whilst the SOAF provides a "factual basis for the conclusion, by operation of the reverse onus not being discharged, that the University … took the adverse action … the SOAF does not provide a basis to infer a positive finding that the Supervisor … was actuated by the proscribed reasoning" (the University's submissions dated 20 October 2023 at [35], original emphasis).
32 Mr Dalton KC for the University made clear in oral submissions that that submission is "not raised in mitigation", but rather it is to guard against "the notion of any aggravating features" (Transcript page 11 lines 9-13).
33 The Ombudsman submits that, by operation of s 361 and the reverse onus, there is a basis to make positive findings that the University engaged in the adverse action for the proscribed reasons. The Ombudsman seeks those positive findings (Transcript page 3 lines 38-44).
34 As is clear from its terms, s 361 operates in such a way that where it is alleged that a person took action for a particular reason, it is presumed that the action was taken for that reason unless the person proves otherwise. On the evidence contained in the SOAF I find, where the Supervisor has not proved otherwise, that the Supervisor made the threat for the reason that Mr Slyfield and Ms Tsongas had made the complaint.
35 In Construction, Forestry, Mining and Energy Union v Pilbara Iron Company (Services) Pty Ltd (No 4) [2012] FCA 894; (2012) 225 IR 113, Katzmann J said at [21]:
I fail to see how the mode of proof has anything to do with the gravity of the contraventions. In this respect I would adopt the applicants' submissions. Section 361 is a procedural provision. It facilitates proof of facts which (generally speaking) only the alleged wrongdoer knows. The fact that I found that the respondent had not rebutted the presumption does not detract from or diminish the importance of the conclusions that the Act had been contravened.
36 In Construction, Forestry, Mining and Energy Union v De Martin & Gasparini Pty Limited (No 3) [2018] FCA 1395, Wigney J said at [49]:
The action taken by De Martin & Gasparini was taken because the workers had those workplace rights, or had exercised them. The fact that the finding that De Martin & Gasparini took the action for that reason, or with that intent, was the outcome of the presumption in s 361 of the Fair Work Act, as opposed to a positive finding, does not lessen the seriousness of the contravention. The fact remains that De Martin & Gasparini was unable to prove that the action was not taken for that reason, mainly because the evidence of their senior officers was found to be unreliable and to lack credibility.
37 Consistent with Katzmann J in Pilbara and Wigney J in De Martin, the method of proof here does not lessen, or indeed worsen, the seriousness of the contravention.
