The Harman obligation
27 In Hearne at [96], the plurality of the High Court described the Harman obligation in the following way:
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.
28 Their Honours noted that it was common to speak of the relevant obligation as flowing from an "implied undertaking": at [97]. Their Honours recorded - quoting a passage from Prudential Assurance Co Ltd v Fountain Page Ltd [1991] 1 WLR 756 at 764-765; [1991] 3 All ER 878 at [885] per Hobhouse J - that this had some benefit in that it confirmed that the obligation was one owed to the court and that the court can modify or release a party from it: at [107]. Nevertheless, their Honours noted that the obligation is one imposed as a matter of law rather than from any implied undertaking and the tendency has increasingly been for the language of implied undertaking to be regarded as "unrealistic, and on balance unmeritorious": at [115].
29 The content of the Harman obligation is such that it recognises and is shaped by inconsistent legal obligations. In Esso Australia Resources Limited v Plowman (1995) 183 CLR 10 (Esso) at 33, Mason CJ (with whom Dawson and McHugh JJ agreed) said:
It would be inequitable if a party were compelled by court process to produce private documents for the purposes of the litigation yet be exposed to publication of them for other purposes. No doubt the implied obligation must yield to inconsistent statutory provisions and to the requirements of curial process in other litigation, eg discovery and inspection, but that circumstance is not a reason for denying the existence of the implied obligation.
(Emphasis added.)
30 Esso concerned documents produced or disclosed to an opposing party in or for the purposes of an arbitration held in private. Brennan J, at 36-7, considered that an obligation of confidentiality would be implied into the arbitration agreement. He said:
I would hold that, in an arbitration agreement under which one party is bound to produce documents or disclose information to the other for the purposes of the arbitration and in which no other provision for confidentiality is made, a term should be implied that the other party will keep the documents produced and the information disclosed confidential except (a) where disclosure of the otherwise confidential material is under compulsion by law; (b) where there is a duty, albeit not a legal duty, to the public to disclose; (c) where disclosure of the material is fairly required for the protection of the party's legitimate interests; and (d) where disclosure is made with the express or implied consent of the party producing the material.
31 He equated this implied obligation of confidentiality with the Harman obligation owed by a party obtaining discovery in an action (footnotes mostly omitted):
To imply an obligation of qualified confidentiality in this way substantially equates the contractual obligation of a party under an arbitration agreement with the obligation of a party who impliedly gives an undertaking of confidentiality to the court when obtaining an order for discovery in an action. The underlying principle in the latter situation is that a party who obtains the production of documents or the disclosure of information for a particular purpose cannot use the documents or information for a "collateral or ulterior purpose" [Citing Alterskye v Scott (1948) I All ER 469 at 470; Central Queensland Cement Pry Ltd v Hardy (1989) 2 Qd R 509 at 510]. That phrase is not used in the pejorative sense, as Lord Diplock said in Home Office v Harman, but it is used "merely to indicate some purpose different from that which was the only reason why, under a procedure designed to achieve justice in civil actions, [the solicitor for a party] was accorded the advantage, which she would not otherwise have had, of having in her possession copies of other people's documents." If the duty of production or disclosure in an arbitration were ordered by a court, an undertaking to the court to use the documents produced or information disclosed only for the purposes of the arbitration would be implied and would be enforced by proceedings for contempt.
32 Later in that paragraph, his Honour said that "the obligation enforceable as an undertaking to the court in the case of a curial order is not unqualified". He then said:
In the present case, the Minister has a statutory right under the State Electricity Commission Act 1958 (Vict) (SEC Act) to obtain information from the State Electricity Commission of Victoria (SECV). It is the duty of SECV to furnish the Minister with the information required under that sub-clause and that duty cannot be defeated by any contractual duty to keep documents or information confidential. Any implied obligation of confidentiality must be qualified accordingly. Further, the Gas and Fuel Corporation of Victoria (GFC) and SECV are public authorities.
33 Whilst his Honour approached the case from the perspective of an obligation of confidentiality which he considered would be implied in the arbitration agreement, his Honour's reasons equate that obligation with the Harman obligation in curial proceedings, both being obligations the content of which he stated were qualified.
34 In Cadbury Schweppes Pty Ltd (ACN 004 551 473) v Amcor Limited (ACN 000 017 372) (2008) ATPR 42-224; [2008] FCA 398, a question arose as to whether documents subject to the Harman obligation because they had been compulsorily produced in one set of proceedings (between Cadbury and Amcor for damages in relation to collusion between Amcor and Visy) were required to be discovered and produced for the inspection of opposite parties (ACCC and Visy) in another proceeding. Gordon J concluded that the Harman obligation did not operate to prevent production in the second set of proceedings, not because a release should be granted (although her Honour noted at [14] that she would have granted one if necessary) but because the Harman obligation had a content which did not trespass on an inconsistent legal obligation. Her Honour stated at [13]:
[T]he resolution of any tension between what would otherwise be competing and inconsistent obligations, is readily apparent; resolution lies in properly identifying the contents of the implied undertaking. In particular, it is necessary to recognise that the undertaking impliedly given in one proceeding not to use documents compulsorily produced in that proceeding except for the purposes of that proceeding is necessarily subject to other requirements of the law. So to take what may be a clearer example of the limits of the undertaking, the implied undertaking given in one proceeding would provide no answer to a subpoena for production of these documents in another proceeding. When a party is subpoenaed to produce documents obtained in another proceeding, it is no answer to say that "I am subject to an undertaking about how I may use these documents". The party's undertaking in the first proceeding restricts the uses to which that party may choose to put the documents. But the undertaking is no answer to otherwise valid compulsive processes of law: Esso Australia Resources Ltd v Plowman (1995) 183 CLR 10, 32, 36-37, 46. As the Court in Plowman stated (at 33):
No doubt the implied obligation must yield to inconsistent statutory provisions and to the requirements of curial process in other litigation, eg discovery and inspection, but that circumstance is not a reason for denying the existence of the implied obligation. (Emphasis added)
35 It would not have been a contempt of Court or a breach of the Harman obligation to have discovered the documents and produced them for inspection in the second proceedings without first seeking a release from the obligation. The obligation simply did not apply to prevent discovery of the documents by the discovering party in the second proceedings, nor - by implication - of inspection of those documents by the other party (irrespective of the fact that the other party had notice that the documents were ones in respect of which a Harman obligation was owed).
36 We agree with this analysis. The same is true in the present case. The Harman obligation does not require the person owing the obligation to refuse to comply with a valid notice issued under s 353-10 or to make an application to the relevant court for release from the undertaking. That is because the content of the obligation does not extend to requiring the holder of the obligation not to comply with such a notice. Nor does the Harman obligation require the Commissioner not to use the documents, when received, for the purpose of discharging his statutory duties and functions.
37 We have set out at [27] above the statement of the Harman obligation in Hearne. In our opinion, providing documents to the Commissioner in answer to the Notice is not use of documents by the person the subject of the Notice. Rather, the true character of providing such documents is compliance with a requirement to give any document to the Commissioner in circumstances where a refusal or failure to give the document, where the person is capable of so doing, is an offence of absolute liability: s 8C of the TAA. An offence under s 8C is punishable on conviction under s 8E.
38 The first respondent submitted that:
(a) the Harman obligation is a "fundamental common law right"; and
(b) s 353-10 does not expressly, or by necessary implication, abrogate the Harman obligation.
39 In support of this submission, the respondent referred to Daniels Corporation International Pty Ltd v Australian Competition and Consumer Commission (2002) 213 CLR 453 (Daniels). In Daniels at [11], Gleeson CJ, Gaudron, Gummow and Hayne JJ stated that legal professional privilege was not merely a rule of substantive law but an important common law right. Their Honours noted it was well-settled that statutory provisions are not to be construed as abrogating important common law rights, privileges and immunities in the absence of clear words or necessary implication.
40 We do not consider this to be the correct approach to the resolution of the present issue. To characterise the Harman obligation as a "fundamental common law right" or a "substantive common law right" distracts attention from the real issue, namely the content or scope of the obligation. The use of the word "right" to describe the Harman obligation is not apt and directs attention away from the obligation on the recipient of the documents. The description "substantive" or "fundamental" does nothing to elucidate the nature of the obligation, but rather assumes some importance or significance which the obligation may or may not have.
41 The respondent relies on the decision of the Full Court of the Family Court in Commissioner of Taxation v Darling (2014) 285 FLR 428. Relying on his information gathering powers then contained in ss 263 and 264 of the ITAA 1936, the Commissioner had obtained documents from a Family Court file in proceedings to which he was not a party. He had sought an order from the primary judge releasing him from an implied obligation not to make use of those documents for purposes other than those of the proceedings. The primary judge had dismissed his application. The Full Court allowed the appeal. This was on the basis that the trial judge erred in exercising her discretion to release the Commissioner from the implied obligation. The Full Court relied upon the conduct of an audit pursuant to the duty and power imposed by s 166 of the ITAA 1936 in concluding that the Commissioner should be released from the implied obligation: at [175] and [198].
42 Before the Full Court, the Commissioner did not contend that the implied obligation must give way to ss 263 and 264 of the ITAA 1936: see [135]. The Full Court considered the Commissioner was correct not to put such an argument because it could not stand in the face of the High Court's decision in Daniels. These comments were obiter. We do not think it correct to equate the Harman obligation to the common law right to legal professional privilege. Daniels concerned the question of whether the common law right to legal professional privilege was abrogated by statute. That is not the question which arises here.
43 The issue was also considered by the New South Wales Court of Appeal in Blanch v Deputy Commissioner of Taxation [2004] NSWCA 461; (2004) 58 ATR 113. Documents had been produced under subpoenas issued in proceedings in the Court of Appeal for the removal of a legal practitioner from the Roll of legal practitioners. After the conclusion of the proceedings, the Commissioner had issued notices under s 264 of the ITAA 1936 requiring production to him of certain documents including documents which had been obtained by the recipients of the s 264 notices by virtue of the subpoenas, such documents therefore being the subject of a Harman obligation.
44 Giles JA (with whom Hodgson and Ipp JJA agreed), in an ex tempore decision, recorded that the Court of Appeal was invited by the claimants to deal with the matter on the basis of whether a release should be granted, even though the Commissioner preferred a resolution of the matter of principle:
[9] At the hearing of the summons the claimants in effect invited us to proceed directly to the question of release of the undertakings. They had filed written submissions as to the interaction between an implied undertaking and s 264, and were willing to argue for the former prevailing over the latter, but they had no interest in doing so if they could be released from the undertakings so as to permit compliance with the s 264 notices. The opponent asked that we decide which of the undertakings and s 264 prevailed over the other, and had filed written submissions supporting the primacy of s 264, but he also submitted that the claimants should be appropriately released from their undertakings.
45 His Honour went on to say:
[11] In my opinion it is not appropriate to decide in this case the important question of the relationship between a Harman v Secretary of State for the Home Department undertaking and s 264. Even if s 264 trumps the undertakings, release of the undertaking will have to be considered, although the result may be automatic …
46 It seems clear that, as indicated by Giles JA at [11], the claimants made plain that, in furtherance of good citizenship, their preference lay in providing the documents to the opponent, and they were really not a contradictor on the prior question. The prior question is the question with which we are presently concerned.
47 In those circumstances, with respect, it is not entirely clear what his Honour intended by the second sentence in [11]. In our view, his Honour was saying no more than that, even if the Court were to hear full argument on and address the question of whether s 264 "trumped" the Harman obligation, it would on the application before it also need to hear full argument on the question of whether a release should be granted in the event it concluded that s 264 did not have the effect contended for by the Commissioner. In our view, his Honour intended to do no more than indicate that the Court was prepared to deal with the matter on the basis of considering whether a release should be granted notwithstanding that a release might not have been required if the Commissioner's argument were correct. His Honour could not be taken as meaning that a Court would still need to consider whether a release should be granted if the Harman obligation did not prevent the recipient of a s 264 notice from complying with it.
