A. The proper meaning of section 49(4)
10Crucial to the meaning of s 49(4) of the Strata Schemes Management Act 1996 is the meaning of "hearing dog". The term is defined in the Macquarie Dictionary as "a dog which is trained to aid people with a hearing disability by alerting them to such noises as the doorbell or the telephone ringing, fire or burglar alarms, et cetera" and in the Oxford English Dictionary as "a dog trained to alert the deaf or hard of hearing to such sounds as the ringing of an alarm, doorbell, or telephone".
11These definitions recognise three components of a hearing dog: it is "trained", it assists persons with a hearing disability, and it provides this assistance by alerting the disabled person to household noises such as doorbells, telephones and alarms.
12It can be noted that the detail of the first and third components is not identified in the dictionaries. Neither the type or scope of training, nor the manner of alerting the disabled person, is defined.
13The owners corporation sought to narrow the ambit of the meaning of "hearing dog", submitting that the term had a technical meaning and applied only to dogs which had a particular period of training (six to eight months), which provided a particular level of assistance (alerting the disabled person to smoke alarms, door knocks, doorbells, alarm clocks, oven times, microwaves, a baby's cry, telephone, telephone typewriter and whistling kettles) and utilized a particular manner of alerting the disabled person (by touching the disabled person and leading them to the source of the sound, except in the case of a smoke alarm where the hearing dog would drop to the floor). The owners corporation relied for this submission on what appeared to be two brochures supplied by the organisation known as Lions Hearing Dogs Inc.
14In my view, the content of these brochures cannot properly be regarded as evidence of a technical meaning of the term "hearing dog". I do not propose to set out the brochures in full. It suffices to say that their content comprises an explanation of the features and training of a Lions hearing dog. They do not purport to indicate anything about other hearing dogs, nor do they contain anything resembling a purported definition of a "hearing dog".
15According to the analysis contained in paragraphs 4.15 and 4.18 of Statutory Interpretation in Australia, (D C Pearce and R S Geddes, 7th ed (2011) LexisNexis) the technical meaning of a term can only be established by evidence of trade usage. There was no relevant evidence before the Tribunal, nor is there any before me. Further, it is more difficult, according to Pearce and Geddes, to confine the ordinary meanings of words by trade usage (which is what is proposed by the owners corporation here) than to extend the ordinary meaning. The brochures supply no evidence of how the term is used in the industry. Rather, they detail the features of a particular type of hearing dog, a Lions hearing dog.
16The Tribunal considered the Lions Hearing Dog Inc material at paragraphs 28 and 54 (Red Appeal Book pp 28 and 36), noted that there was no relevant legislation in New South Wales providing for the accreditation of animals as hearing dogs (at [37] and [54]) and declined to define "hearing dog" in s 49 of the Strata Schemes Management Act 1996 in accordance with the features of a Lions hearing dog. I can find no error in this approach.
17The owners corporation also relied on certain dictionary meanings of "trained" in the Macquarie Dictionary, including "18 to subject to discipline and instruction, educate, drill", "19 to make proficient by instruction and practice as in some professional work" and "21 to discipline and instruct (an animal) to perform specified actions" and also relied on definitions in the Oxford English Dictionary, perhaps the most analogous of which is "to teach (an animal) a particular behaviour, especially to obey orders".
18Neither of these references indicate a narrower, more specific or technical meaning of "hearing dog". If anything, they confirm the ordinary meaning of the phrase indicated earlier that a hearing dog is a dog trained to assist persons with a hearing disability by alerting them to some common household sounds, such as a doorbell or a telephone.
19The owners corporation, before the Tribunal and perhaps to a lesser extent before this Court, relied upon the provisions of s 9(2) of the Disability Discrimination Act 1992 (Cth). Mr and Mrs Drexler disputed the relevance of this provision.
20Section 9(2) of the Disability Discrimination Act 1992 (Cth) provides:
"...
(2) For the purposes of this Act, an assistance animal is a dog or other animal:
(a) accredited under a law of a State or Territory that provides for the accreditation of animals trained to assist a persons with a disability to alleviate the effect of the disability; or
(b) accredited by an animal training organisation prescribed by the regulations for the purposes of this paragraph; or
(c) trained:
(i) to assist a person with a disability to alleviate the effect of the disability; and
(ii) to meet standards of hygiene and behaviour that are appropriate for an animal in a public place.
Note: For exemptions from Part 2 for discrimination in relation to assistance animals, see section 54A."
21Section 54A of the Disability Discrimination Act 1992 (Cth) makes specific provision in respect of assistance animals and discrimination.
22The Tribunal accepted the relevance of the definition in s 9 (at [41], Red Appeal Book p31 N-Q and at [46]-[47], Red Appeal p34 G-N and see generally Red Appeal Book pp31-34). The Tribunal considered the authorities dealing with s 9 of the Disability Discrimination Act 1992 (Cth). The provision and the related authorities led the Tribunal member to conclude (at [46], Red Appeal Book p34) that:
"I am satisfied that it is appropriate to invoke the provisions of s 9(2)(c) of that Act to assist in determining appropriate formal requirements to be applied to a hearing dog in circumstances where there is no provision for the accreditation of a hearing dog under New South Wales law nor is there any provision for accredited animal trainer organisations within New South Wales".
23There is a problem with this approach. Section 9(2)(c) was not enacted until 2009. All of the authorities considered by the Tribunal concerned an earlier version of s 9. In 2009, the Commonwealth Parliament enacted amendments to the Disability Discrimination Act 1992 (Cth) to include a definition of "assistance animal" and replaced s 9 with the current provision. Previous to that date, s 9 provided (see Forest v Queensland Health [2007] FCA 936 at [87]):
"9 Disability Discrimination - Guide dogs, Hearing Assistance Dogs and Trained Animals:
(1) For the purposes of this Act, a person (discriminator) discriminates against a person with:
(a) a visual disability; or
(b) a hearing disability; or
(c) any other disability;
(aggrieved person) if the discriminator treats the aggrieved person less favourably because of the fact that the aggrieved person possesses, or is accompanied by:
(d) a guide dog; or
(e) a dog trained to assist the aggrieved person in activities where hearing is required, or because of any matter related to that fact; or
(f) any other animal trained to assist the aggrieved person to alleviate the effect of the disability, or because of any matter related to that fact;
whether or not it is the discriminator's practice to treat less favourably any person who possesses, or is accompanied by, a dog or any other animal.
(2) Subsection (1) does not affect the liability of a person with a disability for damage to property caused by a dog or other animal trained to assist the person to alleviate the effect of the disability or because of any matter related to that fact."
24The previous provision contains references in its title to "hearing assistance dogs" and also contained references to a "hearing disability" in s 9(1)(b), to "a dog trained to assist the aggrieved person in activities where hearing is required" in s 9(1)(e) and to "any other animal trained to alleviate the effect of the disability" in s 9(1)(f). These references tend to indicate that, at least until 2009, the legislation regarded a "hearing assistance dog" as a dog trained to assist a person with a hearing disability to alleviate the effect of the disability. That definition replicates precisely the definition contained in the current version of s 9(2)(c)(i). This definition is similar to but perhaps more general and of broader scope than the definitions derived from the dictionaries: the latter confine the assistance to alerting the hard of hearing to normal household sounds, the former contemplates potentially a wider range of possible assistance. This difference is of no practical significance in the present case.
25What is of significance, however, is the Tribunal's decision to include in the definition of hearing dog the requirement stated in s 9(2)(c)(ii) of the current provision - that the dog be "trained to meet standards of hygiene and behaviour that are appropriate for an animal in a public place" (see the Tribunal's findings at, for example, [47] Red Appeal Book p34 and [56] Red Appeal Book p37).
26The meaning of s 49(4) of the Strata Schemes Management Act 1996 prior to 2009 must have been uninformed by the un-enacted content of s 9 of the Disability Discrimination Act 1992 (Cth) and, in particular, s 9(1)(c)(ii) of that Act. The provision, as it formerly existed, did not contain any reference to hygiene or behaviour in a public place so there was no scope to construe s 49(4) of the Strata Schemes Management Act 1996 as embracing this requirement.
27Moreover, it might be doubted whether a Commonwealth enactment changing the definition of a term could properly influence the definition of a related but not identical term in a State Act.
28It may be that the common law can be influenced by the "gravitation pull" of statutes (see Pilmer v The Duke Group Ltd (in liq) [2001] HCA 31, (2001) 207 CLR 165 at 230 [170]), but it seems less likely that the meaning of statutory terms in one jurisdiction would be affected by later enactments in another. Nor is it likely that principles that might allow constitutional meanings to change over time would have any application to a State Act dealing with a subject so prosaic as dogs (compare Baker v R [2004] HCA 45, (2004) 223 CLR 513 at [56]).
29In these circumstances, I do not accept that the requirement in s 9(1)(c)(ii) of the Disability Discrimination Act 1992 (Cth), by its enactment in 2009, can impact on or be incorporated in the meaning of "hearing dog" in s 49(4) of the Strata Schemes Management Act 1996. In my respectful view, the Tribunal was in error to find otherwise.
30But the question still remains as to whether the ordinary meaning of "hearing dog" embraces a requirement of public behaviour similar to that included in s 9(1)(c)(ii) of the Strata Schemes Management Act 1996, even though no such requirement is found in dictionaries. For what it is worth, there is little reference to this sort of training in the Lions Hearing Dog Inc brochures which, on the subject of alerting the hard of hearing to household sounds, go into great detail. One brochure (Blue Appeal Book p100 R) speaks of the dog being "entitled to enter any public place and use all forms of public transport" which, of course, says nothing of training. The other brochure (Blue Appeal Book p101 R) goes a little further, referring to "other training includes obedience and extensive socialisation...accompanying their owners into public areas such as supermarkets...transport". The brochure does not indicate how the hearing dog might, if at all, alleviate a hearing disability in public.
31I think the Court can take judicial notice of the fact that guide dogs often accompany their owners in public places and there provide assistance to them. That circumstance may support a requirement for "training to meet standards of hygiene and behaviour ... in a public place" in respect of guide dogs. But I am not persuaded that the same requirement applies to a hearing dog. The primary, perhaps exclusive role, of a hearing dog is to assist the hard of hearing to respond to some normal household sounds. The benefit of a hearing dog seems essentially to be "in the home", which is quite different from the place of the benefits, or at least some of them, provided by a guide dog.
32Further, the use of s 49(4) of the Strata Schemes Management Act 1996 is confined to the "keeping on a lot" of the dog, or the "use" of a dog "on a lot or common property". That is, s 49(4) is focused on the presence of the dog in and around the home of the owner and not in a public place. This may provide some further support for the conclusion to which I have come.
33For these reasons, I conclude that the proper meaning of a hearing dog in s 49(4) is a dog trained to assist a person with a hearing disability by alerting them to some normal household sounds, such as a telephone or a doorbell. It is not, in my opinion, necessary that the dog meet some standard of hygiene and behaviour in a public place in order to be a hearing dog under s 49(4). Of course, many hearing dogs may meet such standards. There is some evidence that Lions hearing dogs have obedience training in public places and I consider later in these reasons whether, in any event, there was evidence that Larry satisfied such behavioural standards. But if a dog is trained and able to alert the hearing impaired owner to a range of household sounds, that dog, in my view, does not cease to be a "hearing dog" if it, for example, tends to bark in public. It may just be a poorly behaved hearing dog.
34The next question that arises is whether the ambit of s 49(4) is affected by the use of the words "dog used as" a hearing dog. Mr and Mrs Drexler submitted that this broadened the scope of s 49(4), that it applied to more than just hearing dogs but includes also dogs used for that purpose.
35On the other hand, the owners corporation submitted that these words narrowed the range of dogs falling within the protection of s 49(4). It submitted that the phrase "dog used as a ... hearing dog" means "a hearing dog used as a hearing dog" so that the particular animal needed to be both a hearing dog and so used.
36In my view, the presence of these words "dog used as" do not work a substantial change to the range of animals falling within s 49(4). I accept that it is not enough that an animal be a trained hearing dog to fall within s 49(4) if it is not being used to assist the hearing impaired person. But on the other hand, the words seem to focus on the use being made of the dog, rather than its training, description, title or status. If a dog is doing the job of a hearing dog, that is sufficient. Of course, without training, a dog is unlikely to be able to perform the function of assisting the hearing impaired to respond to normal household sounds. Further, evidence of training would indirectly support the conclusion that a dog is being so used. Nevertheless, the phrase "used as a hearing dog" directs attention not directly to the training the dog has received but, rather, to the activities and functions the dog performs. The object of the provision supports a focus on the substance of what the dog does, rather than the formal nature of its training (see for example, Project Blue Sky Inc v Australian Broadcasting Authority (1998) 194 CLR 355, 381 at [69]).
37In my view, a dog is "used as a hearing dog" if a not insignificant part of its function is to alert a person with a hearing disability to normal household sounds. A dog with this quality is a dog that falls within the ambit of s 49(4) of the Act.
38During the course of this appeal, the owners corporation sought to draw a distinction between a person hard of hearing and a person with a hearing disability. I do not think any such distinction should be drawn and, in any event, I understood that this distinction was not pressed by the end of the submission. If such a difference exists, it is not material to the matter before me as will appear.
39The owners corporation also made the related submission that a hearing dog needed to be trained to deal with a profoundly or totally deaf person, as well as a person hard of hearing. The use of the disjunctive in the Oxford definition and the reference to "hearing disability" in the Macquarie definition does not support this submission. In my view, a dog can be a hearing dog if the dog is trained to alleviate the disability of the hearing impaired person even if that training would not enable a dog to assist a person who is profoundly deaf. The definition of "deaf" in the Macquarie Dictionary is "wholly or partially unable to hear" which also does not assist the owners corporation's submission.
40The Tribunal appeared not to distinguish between a "hearing dog" and a "dog used as a hearing dog" (cf paragraphs 46 and 47). For reasons that I have given, in my view, there is little practical difference between the two. The former is concerned principally with the training of the dog, the latter with its use. But as a practical matter, it is necessary that a dog, to be used as a hearing dog, be trained so that it can provide the assistance that a hearing dog is trained to provide. In these circumstances, I do not regard the attention the Tribunal gave to training as an error: the training was appropriately part of the method of identifying whether the dog was genuinely being used as a hearing dog.
