FIRST BASIS OF OPPOSITION: BREACHES HARMAN OBLIGATIONS
11 The High Court described the Harman obligation in Hearne v Street (2008) 235 CLR 125 ('Hearne') at [96] (per Hayne, Heydon and Crennan JJ) as follows:
Where one party to litigation is compelled, either by reason of a rule of court, or by reason of a specific order of the court, or otherwise, to disclose documents or information, the party obtaining the disclosure cannot, without the leave of the court, use it for any purpose other than that for which it was given unless it is received into evidence.
12 The Harman obligation applies to documents and information disclosed compulsorily in the course of a proceeding, including discovered documents and documents produced pursuant to a subpoena: see, eg, Springfield Nominees Pty Ltd v Bridgelands Securities Ltd (1992) 38 FCR 217 at 222-223; Hearne at [96]. This is to ensure that privacy and confidentiality are not invaded more than is necessary for the purpose of doing justice: Hearne at [107].
13 The obligation is breached when documents obtained by compulsory process are used for a purpose other than the purpose for which the documents were given, unless the documents are received into evidence or leave is given: Hearne at [96]. That other purpose has been described as 'collateral' or 'ulterior' to the purpose for which the documents were produced: see, eg, Allstate Life Insurance Co v Australia & New Zealand Banking Group Ltd (1995) 57 FCR 360 ('Allstate').
14 The Harman obligation is a substantive obligation: Hearne at [105]-[108]. A breach of the Harman obligation may be prevented by the Court by either declining to grant leave sought by a party to take a step in a proceeding that is in breach of that party's Harman obligations, or by ordering a stay of the relevant court process that gives rise to the breach: see, eg, Connective Services Pty Ltd v Slea Pty Ltd (2017) 53 VR 130 ('Connective Services'). As already noted, in the present proceeding NAB sought to oppose leave being granted to the Applicant by way of both forms of relief: it opposed leave being granted to the Applicant simpliciter, and also sought a stay of the Applicant's interlocutory application in the manner granted by Almond J in Connective Services.
15 Turning to the Applicant's proposed new case, it must first be said that there is no doubt that the Applicant has 'used' the documents it obtained by way of discovery and subpoena in making the proposed amendments to its pleadings. This is supported by the affidavit evidence relied on by both the Applicant and NAB.
16 NAB rightly accepted that the Applicant is entitled to use the relevant documents to amend her existing claim to, for instance, include additional or different relief in relation to credit card insurance. That would not breach her Harman obligations. However, on NAB's submission, the amendments were such as to mount an entirely new case in relation to personal loan insurance, which it characterised as an entirely different insurance product.
17 I interpolate that, on one view, it may be that a permissible purpose for which documents protected by Harman may be used is simply the use of such documents in the same proceeding: see Allstate at 378-379. However, I proceed on the basis that there must be some 'reasonable relation', to use the language of Ryan J in Arnold Mann v Medical Defence Union Ltd [1997] FCA 45 ('Mann'), between the existing case and the 'new' case.
18 In support of this, NAB identified a number of features that rendered the use of the relevant documents to prosecute the Applicant's case regarding personal loan insurance products inimical to her implied Harman undertaking:
(1) NAB Personal Loan Cover has different terms and conditions, different premiums and different benefits as compared to NAB Credit Card Cover, and the products are neither linked nor operate inter-dependently;
(2) the Applicant has never applied for or received a personal loan from NAB, and has never applied for or received a personal loan insurance product; and
(3) as a result of (1) and (2) above, the Applicant lacks standing to bring claims for relief in relation to NAB Personal Loan Cover in freestanding proceedings.
19 NAB contended that, having regard to the features it identified, the Applicant's use of the documents to found a claim concerning personal loan insurance products would be for a purpose that is 'collateral' or 'ulterior' to the purpose for which the documents were produced. Adopting the approach taken by Chesterman JA in Northbuild Construction Pty Ltd v Discovery Beach Project Pty Ltd (No 4) [2011] 1 Qd R 145, NAB characterised the issue in the following way:
[T]he documents [the Applicant] seeks to use in aid of the new claim concerning personal loan insurance were not disclosed for the purpose of resolving that claim, but were disclosed to assist in the resolution of a dispute concerning something else entirely - namely, a dispute concerning the issue of NAB Credit Card Cover.
20 NAB also evaluated the issue through a different lens. In Mann, Ryan J asked whether the new claim operates independently of the existing case made by the Applicant. In that case, his Honour held that a proposed new defamation claim:
[C]ould succeed or fail quite without reference to the resolution of the other existing issues between the parties. I therefore regard it as entirely collateral to the attack which the applicant seeks to mount through the remaining parts of his proposed further amended statement of claim.
21 Because, on NAB's submission, the two insurance products were sufficiently different, and the causes of action between the existing case and the proposed new case were sufficiently distinct, the Applicant should not be granted leave to amend her pleadings, or in the alternative, her interlocutory application seeking the same should be stayed as was done in Connective Services.
22 However, I am not persuaded that there exist such differences between the two insurance products so as to compel me to accede to NAB's submissions. In other words, I consider the claims in respect of NAB Credit Card Cover and the proposed claims in respect of NAB Personal Loan Cover are sufficiently connected for the Applicant's proposed amendments not to breach her implied Harman undertaking.
23 In this regard, despite the differences raised by NAB, the following similarities between the insurance products and the manner in which they were marketed or sold are relevant:
(1) The type of policy is the same. Each product comprised of insurance in relation to a financial product that the relevant customer held with NAB.
(2) The material terms of the two insurance products are the same or substantially similar. Each provide four forms of cover: 'life', 'critical illness', 'disability' and 'involuntary unemployment' cover. Both products were subject to the same policy exclusions.
(3) To the extent known, the manner of sale of the products was substantially the same. NAB arranged the sale and issue of its personal loan and credit card insurance, with sales conducted by NAB's website, by direct mail and by telephone. NAB Personal Loan Cover was also sold by staff members at local branches.
(4) The possible issues with the insurance products are the same. In each case, customers who were not 'gainfully employed' at the time of entry into either form of insurance were said to be unlikely to benefit from the 'involuntary unemployment' cover or the 'disability' cover. Similarly, customers who had a critical illness (or a pre-existing condition, with respect to NAB Personal Loan Cover) were said to be unlikely to benefit from the 'critical illness', 'life' or 'disablement' cover.
(5) Finally, the relevant factors to which a Court may have regard under s 12CC(1)(a) of the ASIC Act - being the section that sets out the matters a court may have regard to for the purposes of determining whether a person has contravened s 12CB of that Act, relevantly the section invoked by the Applicant in the primary proceeding - are substantially the same:
(a) whether NAB and MLC had significantly stronger bargaining positions than each of the customers in arranging the issue of the policies (and, with respect to MLC, in issuing and giving effect to the policies);
(b) whether the customers were able to understand the documents constituting the credit insurance policies, and in particular the terms relating to their eligibility for the benefits;
(c) the availability of identical or equivalent credit insurance policies from companies other than NAB and MLC (albeit that the analysis of the amount for which and circumstances under which such products could be acquired may differ);
(d) the requirements on NAB under the Code of Banking Practice; and
(e) the extent to which NAB and MLC were willing to negotiate the terms and conditions of the credit insurance policies (under each, it is alleged that the terms were standard terms which NAB and MLC were not willing to negotiate with the customer; that the customer was not given an effective opportunity to negotiate the terms; that MLC had a unilateral right to vary the terms and conditions).
24 This, in my view, supports the conclusion that there exists a reasonable relationship between the claims concerning the two insurance products, such that the Applicant ought to be granted leave to amend its pleading in the manner proposed.
25 I acknowledge that the Applicant did not have NAB Personal Loan Cover. However, this is of no moment as she is, as I will explain, entitled to bring the claim as a representative of the group members. In addition, Part IVA of the FCA Act provides for mechanisms, including the bringing before the Court of sample group members, to allow for the adjudication of all group member claims.
26 Even if I am wrong in reaching this conclusion and the Harman obligation does arise in respect of the documents obtained and the Applicant's proposed new case, the Applicant ought to be relieved of her implied Harman undertaking in view of the special circumstances that exist in this case. Those special circumstances include the facts that:
(1) the relevant documents were provided to the Applicant after NAB had the opportunity to make extensive redactions;
(2) the use of the information gleaned from the document is very confined in the context of amendments otherwise made based on publicly available information;
(3) the documents are not marked 'confidential' and nor were they prepared in circumstances that suggest they were intended to remain confidential; and
(4) the use of the documents to allow the proposed amendments will avoid a multiplicity of proceedings, in circumstances in which the law 'strongly favours the avoidance of a multiplicity of proceedings': Pinara Group Pty Ltd v Whiting [2013] FCA 1378 at [34]; see also Allstate at 379.
27 For these reasons, I reject NAB's first basis of opposition.
