The claim does not disclose indirect discrimination
44 The claim of indirect discrimination also faces numerous obstacles. I have already mentioned the most obvious one: the applicants refuse to say what their disabilities were, and have not provided any evidence of the disabilities. The claim of indirect discrimination thus breaks down because no arguable basis is disclosed for thinking that the applicants could not comply with any relevant requirement or condition because of their disability, or that the requirement or condition has, or is likely to have, the effect of disadvantaging persons with the disability.
45 The applicants' argument as to causation, that the officers 'accosted' them (imposed a requirement) because of their disability, does not support any finding of indirect discrimination. It must be their inability to comply with the requirement, not the imposition of the requirement, that is caused by the disability. This they cannot establish.
46 Also, the applicants have not sufficiently identified the nature of the requirement or condition the police are said to have imposed so as to give rise to indirect discrimination. The judgment of Gleeson CJ in State of New South Wales v Amery [2006] HCA 14; (2006) 230 CLR 174 shows that it is important to pay close attention to the nature of the alleged requirement or condition. Here, it seems, it could be either or both of two things: a requirement to wear a mask when passing through the airport; or a requirement to produce medical evidence of a medical condition that makes wearing masks unsuitable, in order to be permitted to pass through the airport. The applicants' materials put some emphasis on the latter, as the complaint made in the particulars is that the police 'automatically' excluded from the airport 'anyone not able to provide proof that they suffered from a medical condition that made it unsuitable to wear a face mask'. If it is the requirement to provide proof that is the relevant requirement, it is impossible to see how that could have resulted in indirect discrimination, because there is no basis in the allegations to suggest that the applicants' disability was the cause of their failure or refusal to produce evidence of the disability. Any claim that it was would be incoherent.
47 The above is sufficient to compel the conclusion that the claim of indirect discrimination must fail. It is also appropriate to note two other respects in which it is problematic, as they were the subject of submissions from the Commissioner.
48 First, the Commissioner submits that even if there was unlawful discrimination, it did not occur in one of the protected areas of life in Part 2 of the DDA. The first area that is relevant here concerns public premises: DDA s 23. The Commissioner submits that s 23 did not apply because he did not have any control of or authority over access to or use of the airport in the sense contemplated by that section. The submission appears to be that s 23 cannot apply to a person who was not the owner, occupier, operator or controller of the airport.
49 While as a matter of construction that is arguable, I do not consider it necessary to determine this application on that basis, or appropriate to do so in the absence of full argument. The only authority on which the Commissioner relies, Ellis v FJM Property Pty Ltd (No 2) [2019] FCCA 1821 at [26], is potentially distinguishable because the judge's comments there appear to be directed to a situation where the claim was made on a mistaken assumption that the respondent had some interest in the relevant premises or the business conducted on them. The status of the police as (arguably) controlling access to the airport for the purposes of the Face Mask Direction may put them in a different category.
50 As for the other potentially relevant area of life, s 24, the applicants' claim there is plainly incoherent. Their allegation is that the police on behalf of the Commissioner were providing a service, not to the applicants, but to 'the Airport Police'. But all the forms of discrimination enumerated in s 24 involve the provision of services to the aggrieved person or a refusal to provide those services to the aggrieved person (or, similarly, making facilities available to the aggrieved person or refusing to do so). Even if the Western Australian Police were providing services to 'Airport Police', that could not found a claim of discrimination by the applicants. So any claim under s 24 must fail.
51 Second, the Commissioner also submits that his conduct was reasonable, and that this is an insurmountable obstacle in the way of the applicants' complaint: see s 6(3) of the DDA. I agree that the applicants' case in relation to this issue appears weak. Gleeson CJ's judgment in Amery indicates that one reason it is important to identify the requirement alleged to give rise to indirect discrimination is that the reasonableness of the respondent's conduct must be judged by reference to the requirement. Here, it is the conduct of the Commissioner (or his officers) in imposing the requirement that is to be judged as reasonable or not: see Amery at [3], [15]. Importantly, it is not the Face Mask Direction itself that is alleged to be discriminatory here. It is what the officer(s) did at the airport that is said to have involved discrimination, and the alleged conduct of the Commissioner in instructing or allowing them to do it: cf. Amery at [17]. The Face Mask Direction is but one of the circumstances against which the conduct of the respondent must be judged: see Amery at [13].
52 Here it is a particularly important circumstance. The police officers were at the airport in order to ensure compliance with the Face Mask Direction. That direction imposed legal obligations which it was their responsibility to enforce. I have described the relevant obligation to wear a mask above, including the exception which applies when a person has a 'physical or mental illness, condition or disability which makes wearing a face mask unsuitable'. In that context, it is difficult to see how it could have been unreasonable for the police officers to require people who were unmasked, and who did not produce evidence of such a physical or mental illness, condition or disability, to wear a mask before being allowed to move through the airport. In imposing that requirement, the officers were giving effect to the Face Mask Direction, which had force of law under s 86 of the Emergency Management Act.
53 The submissions made by the applicants do not articulate relevant unreasonableness in any coherent way. As I have said, they do not clearly identify the requirement that was allegedly imposed, but in connection with reasonableness they do seem to place emphasis on an alleged requirement to produce medical evidence. The submissions say that the police officers 'were not permitted to demand the production of the Applicants' private medical information under the provisions of any WA state legislation' and that there was 'no reasonable ground on which the officers could presume that the Applicants were committing an offence'. The submissions assert that once the applicants told the officers that they suffered from medical conditions that made it unsafe to wear a face mask, 'any reasonable suspicion ended'. This amounts to an assertion that where a person who may be committing an offence tells a police officer that they have a lawful excuse, the police officer must take the person at their word, and it is not reasonable for the officer to inquire further or require verification of the excuse. That only needs to be stated to be seen to be false.
54 I therefore agree that it appears likely that the conduct of the police officer(s) in imposing any relevant requirement was reasonable. But as I have indicated, it is open to characterise the relevant requirement, not as the requirement to produce medical evidence of the disability, which seems to have been reasonable, but also as a broader requirement not to proceed through the airport without a mask. Also, I am conscious that the question of reasonableness is a question of fact that depends on all the circumstances, and also that the burden of proof for that question would be on the Commissioner. In relation to this defence then, the absence of evidence may be an issue for the Commissioner. I therefore will not dismiss the application for leave on the ground that the conduct of the police officer(s) in imposing any relevant requirement was reasonable. It is enough to dismiss it on the bases that it lacks any evidentiary foundation, and that the alleged disabilities have not been particularised or otherwise described, and that the apparent complaint that indirect discrimination arose from a requirement to produce medical evidence is incoherent.
