The disputed questions
12 The disputed questions are questions 44, 45 and 46 which appear under the subheading "Goods not of merchantable quality, non-compliant with Acceptable Quality Guarantee". They are in the following terms:
CQ44. By reference to the answers to the questions at paragraphs CQ19 and/or CQ20 and CQ42, was Alucobond PE Core Cladding fit for all the purposes for which goods of that kind were commonly bought?
CQ45. By reference to the answers to the questions at paragraphs CQ26 and CQ43, was Alucobond PE Core Cladding fit for all the purposes for which goods of that kind were commonly bought?
CQ46. By reference to the answers to the questions at paragraphs CQ44 and/or CQ45, was the Alucobond PE Core Cladding fitted to the Relevant Buildings and/or Relevant Building Parts of merchantable quality and compliant with the Acceptable Quality Guarantee?
13 As can be seen, the questions posed in questions 44 and 45 are to be answered by reference to the answers to other questions, questions 19, 20, 26, 42 and 43. It is unnecessary to refer to those questions in detail. It suffices to say that they pose various factual questions in relation to the properties or qualities of the relevant goods, including whether by reason of those properties the goods posed certain risks, or were not fit for certain purposes or were compliant or not with certain relevant codes.
14 It is common ground that the disputed questions address, or purport to address, the statutory tests in s 74D of the TPA and s 54 of the ACL.
15 Section 74D of the TPA provides as follows:
74D Actions in respect of goods of unmerchantable quality
(1) Where:
(a) a corporation, in trade or commerce, supplies goods manufactured by the corporation to another person who acquires the goods for re-supply;
(b) a person (whether or not the person who acquired the goods from the corporation) supplies the goods (otherwise than by way of sale by auction) to a consumer;
(c) the goods are not of merchantable quality; and
(d) the consumer or a person who acquires the goods from, or derives title to the goods through or under, the consumer suffers loss or damage by reason that the goods are not of merchantable quality;
the corporation is liable to compensate the consumer or that other person for the loss or damage and the consumer or that other person may recover the amount of the compensation by action against the corporation in a court of competent jurisdiction.
(2) Subsection (1) does not apply:
(a) if the goods are not of merchantable quality by reason of:
(i) an act or default of any person (not being the corporation or a servant or agent of the corporation); or
(ii) a cause independent of human control;
occurring after the goods have left the control of the corporation;
(b) as regards defects specifically drawn to the consumer's attention before the making of the contract for the supply of the goods to the consumer; or
(c) if the consumer examines the goods before that contract is made, as regards defects that the examination ought to reveal.
(3) Goods of any kind are of merchantable quality within the meaning of this section if they are as fit for the purpose or purposes for which goods of that kind are commonly bought as it is reasonable to expect having regard to:
(a) any description applied to the goods by the corporation;
(b) the price received by the corporation for the goods (if relevant); and
(c) all the other relevant circumstances.
16 Section 54 of the ACL provides as follows:
54 Guarantee as to acceptable quality
(1) If:
(a) a person supplies, in trade or commerce, goods to a consumer; and
(b) the supply does not occur by way of sale by auction;
there is a guarantee that the goods are of acceptable quality.
(2) Goods are of acceptable quality if they are as:
(a) fit for all the purposes for which goods of that kind are commonly supplied; and
(b) acceptable in appearance and finish; and
(c) free from defects; and
(d) safe; and
(e) durable;
as a reasonable consumer fully acquainted with the state and condition of the goods (including any hidden defects of the goods), would regard as acceptable having regard to the matters in subsection (3).
(3) The matters for the purposes of subsection (2) are:
(a) the nature of the goods; and
(b) the price of the goods (if relevant); and
(c) any statements made about the goods on any packaging or label on the goods; and
(d) any representation made about the goods by the supplier or manufacturer of the goods; and
(e) any other relevant circumstances relating to the supply of the goods.
(4) If:
(a) goods supplied to a consumer are not of acceptable quality; and
(b) the only reason or reasons why they are not of acceptable quality were specifically drawn to the consumer's attention before the consumer agreed to the supply;
the goods are taken to be of acceptable quality.
(5) If:
(a) goods are displayed for sale or hire; and
(b) the goods would not be of acceptable quality if they were supplied to a consumer;
the reason or reasons why they are not of acceptable quality are taken, for the purposes of subsection (4), to have been specifically drawn to a consumer's attention if those reasons were disclosed on a written notice that was displayed with the goods and that was transparent.
(6) Goods do not fail to be of acceptable quality if:
(a) the consumer to whom they are supplied causes them to become of unacceptable quality, or fails to take reasonable steps to prevent them from becoming of unacceptable quality; and
(b) they are damaged by abnormal use.
(7) Goods do not fail to be of acceptable quality if:
(a) the consumer acquiring the goods examines them before the consumer agrees to the supply of the goods; and
(b) the examination ought reasonably to have revealed that the goods were not of acceptable quality.
17 When consideration is given to the terms of both s 74D of the TPA and s 54 of the ACL, three things can be noted concerning the disputed questions.
18 First, questions 44 and 45 utilise the language found in s 74D of the TPA, rather than the language used in s 54 of the ACL. The parties nevertheless proceeded on the basis that there are no material differences between the language employed in the two sections.
19 Second, and more significantly, it can be seen that, while questions 44 and 45 purport to address the question whether the relevant goods were "fit for the purpose or purposes for which goods of that kind are commonly bought" (s 74D(3) of the TPA) or "fit for all the purposes for which goods of that kind are commonly supplied" (s 54(2)(a) of the ACL), in fact they do not address those statutory questions in their entirety. In particular, the questions do not include, in the case of s 74D(3), the words "as is reasonable to expect having regard to" or any of the words in paragraphs (a), (b) and (c). In the case of s 54(2), the questions do not include the words "as a reasonable consumer fully acquainted with the state and condition of the goods (including any hidden defects of the goods), would regard as acceptable having regard to the matters in subsection (3)" or any of the words in subsection (3).
20 Third, the effect of question 46 is to ask whether, having regard to the answers to questions 44 and 45, the relevant goods comply with the requirement of "merchantable quality" in s 74D of the TPA and comply with the "acceptable quality" guarantee in s 54 of the ACL. In effect, the question asks whether, having regard to the answers to questions 44 and 45, there has been a contravention of s 74D(1) of the TPA giving rise to a liability to compensate the consumer and a contravention of the acceptable quality guarantee in s 54(1), which gives rise to liability under s 271 of the ACL. It may be noted, however, that the question does not address whether any of the circumstances in s 74D(2) exist, in which case s 74D(1) would not apply. Similarly, it does not address whether any of the circumstances in s 54(7) of the ACL exist, in which case the goods would not fail to be of acceptable quality and therefore would not give rise to a contravention of the acceptable quality guarantee.
21 Putting those apparent drafting difficulties to one side for the moment, the critical question is whether the statutory questions purportedly posed by the disputed questions can be answered by reference to facts and circumstances which are common to all group members, or whether they can only be answered by having regard to the individual circumstances of the group members, or the specific circumstances in which the goods were supplied to each group member.
