(a) any serious adverse effects the tenancy has had on neighbouring residents or other persons,
(b) whether any breach of the residential tenancy agreement was a serious one (and, in particular, whether it was one to which subsection (6) applies), and whether, given the behaviour or likely behaviour of the tenant, a failure to terminate the agreement would subject, or continue to subject, neighbouring residents or any persons or property to unreasonable risk,
(c) the landlord's responsibility to its other tenants,
(d) whether the tenant, wilfully or otherwise, is or has been in breach of an order of the Tribunal,
(e) the history of the tenancy concerned, including, if the tenant is a tenant under a public housing tenancy agreement, any prior tenancy of the tenant arising under any such agreement."
52 The evidence of the plaintiff may well have been decisive on such questions as "the circumstances of the tenant" given that on the hearing date she was over six months pregnant. Similarly, her evidence would also have been important on the other matters specifically referred to in s64(4) of the Residential Tenancies Act.
53 In those circumstances I am persuaded that, procedural unfairness having occurred, this Court ought intervene to set aside the findings of the Tribunal so as to allow to the plaintiff the opportunity to attend the hearing and give evidence on those issues.
54 For completeness, I should deal with the second basis for this Court intervening, i.e. error on the face of the record, that error being of a jurisdictional kind. The error relied upon was a failure to take into account relevant considerations and taking into account irrelevant considerations. As the argument progressed, however, the basis of the plaintiff's complaint was that the Tribunal had made findings pursuant to s64 of the Residential Tenancies Act for which there was no evidence before it.
55 The High Court in Kirk v Industrial Relations Commission of NSW [2010] HCA 1, (2010) 84 ALJR 154 identified how errors of law could arise on the face of the record and how those errors of law were jurisdictional errors on the facts of that case. The question of lack of evidence and its consequences in relation to decisions of the Tribunal was considered by French CJ in Kostas v HIA Insurance Services Pty Limited [2010] HCA 32 where his Honour said:
"15 The Tribunal may, subject to the CTTT Act determine its own procedure. It is not bound by the rules of evidence and may inquire into, and inform itself on, any matter in such manner as it thinks fit, subject to the rules of procedural fairness. That freedom is enjoyed by many administrative tribunals. The term "rules of evidence" does not lay out with precision its metes and bounds. Nor does it exclude the discretionary application of such rules. But the authority of the Tribunal to "inform itself on any matter in such manner as it thinks fit" indicates that it is able to act upon information whether or not it is embodied in evidence which would be admissible in a court of law.
16 There are qualifications upon the Tribunal's procedural freedom. One, which is explicit, is the requirement to observe procedural fairness. The Tribunal's modus operandi must also serve its function, which, in this case, was to hear and determine a building claim. That function implies a rational process of decision-making according to law. A decision based on no information at all, or based on findings of fact which are not open on information before the Tribunal, is not compatible with a rational process.
17 The exercise of the Tribunal's freedom from the rules of evidence should be subject to the cautionary observation of Evatt J in R v War Pensions Entitlement Appeal Tribunal; Ex parte Bott that those rules "represent the attempt made, through many generations, to evolve a method of inquiry best calculated to prevent error and elicit truth". It is a method not to be set aside in favour of methods of inquiry which necessarily advantage one party and disadvantage another. On the other hand, that caution is not a mandate for allowing the rules of evidence, excluded by statute, to "creep back through a domestic procedural rule"."
56 The Tribunal's findings which are challenged on this basis relate to the application of s 64 of the Residential Tenancies Act. In that regard the Tribunal said:
"42 In relation to the specific social housing considerations in s 64(4), Mr Jungwirth stated that there was no direct evidence of the effects on neighbouring residents and other persons. However, it was clear that the premises had been used, perhaps for some time, for the purpose of storing and packaging of prohibited drugs, and this has the potential for very serious social consequences. The landlord as a large social housing provider has responsibilities for all of its other tenants, and the location of the tenant's premises in a large housing estate, makes this particularly significant. The tenant's premises are in a large housing estate consisting entirely of Department of Housing properties. There are a large number of other tenants of the landlord who could be significantly affected by the illegal activities occurring in her premises.
