THE IMPLIED UNDERTAKING
22 During the course of the hearing of the present Interlocutory Application at least five propositions were common ground as between the parties, namely:
(i) the documents produced to the Court pursuant to each of the subpoenas were subject to an "implied undertaking" that they would only be used for the purposes of resolving the proceeding in which the subpoenas had been issued;
(ii) an "implied undertaking" ceases upon the documents being admitted into evidence in open court;
(iii) the Court has a discretionary power to release a person from the "implied undertaking";
(iv) the discretionary power "is not freely exercised, but it will be exercised when special circumstances appear"; and
(v) the onus lies upon those who seek to be released from the undertaking to persuade the Court that such an order should be made.
It was the application of these general propositions that divided the parties.
23 In the absence of an order to the contrary, it was thus accepted that documents which are produced to a superior court pursuant to the compulsory processes of that court - such as a subpoena - can only be used for the purposes of the proceeding in which they are produced. Documents so produced cannot be used for any "collateral or ulterior" purpose. The limitation upon the use of documents so produced is founded (at least in part) upon protecting the public interest in the administration of justice. Any intrusion upon the privacy of those compulsorily required to produce documents is to be no greater than is necessary to ensure that justice is done between the parties. See: Groves, The implied undertaking restricting the use of material obtained during legal proceedings (2003) 13 Aust Bar Rev 314.
24 Although this constraint upon the use of documents so produced is commonly referred to as an "undertaking", there is nothing voluntary about it; the constraint is a substantive obligation. Thus, in Hearne v Street [2008] HCA 36, 235 CLR 125 Hayne, Heydon and Crennan JJ set forth the reach of the "implied undertaking" as follows:
[96] 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. The types of material disclosed to which this principle applies include documents inspected after discovery, answers to interrogatories, documents produced on subpoena, documents produced for the purposes of taxation of costs, documents produced pursuant to a direction from an arbitrator, documents seized pursuant to an Anton Piller order, witness statements served pursuant to a judicial direction and affidavits. …
In concluding that the "implied undertaking" is an obligation of substantive law, their Honours went on to observe:
[106] The fact that the role of the word "undertaking" is merely to indicate the way in which an "obligation" which is "imposed by law" as a "condition" of discovery binds the disclosee highlights the substantive nature of the obligation. There is nothing voluntary about the "undertaking"…
[107] The expression "implied undertaking" is thus merely a formula through which the law ensures that there is not placed upon litigants, who in giving discovery are suffering "a very serious invasion of the privacy and confidentiality of [their] affairs", any burden which is "harsher or more oppressive … than is strictly required for the purpose of securing that justice is done.'…
Gleeson CJ agreed with Hayne, Heydon and Crennan JJ: [2008] HCA 36 at [3], 235 CLR 125 at 131.
25 The concern of courts to ensure that documents produced pursuant to their compulsory processes are used only for the purposes of resolving the proceeding in which they are produced has often been repeated and has long been recognised. In Esso Australia Resources Ltd v Plowman (1995) 183 CLR 10 at 32-33, for example, Mason CJ had observed:
In relation to documents produced by one party to another in the course of discovery in proceedings in a court, there is an implied undertaking, springing from the nature of discovery, by each party not to use any document disclosed for any purpose otherwise than in relation to the litigation in which it is disclosed. Over a century ago, Bray on Discovery stated:
"A party who has obtained access to his adversary's documents under an order for production has no right to make their contents public or communicate them to any stranger to the suit … nor to use them or copies of them for any collateral object … If necessary an undertaking to that effect will be made a condition of granting an order."
Because an undertaking is implied, it has not been the practice to condition the making of orders in that way. The implied undertaking is subject to the qualification that once material is adduced in evidence in court proceedings it becomes part of the public domain, unless the court restrains publication of it.
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.
McHugh and Dawson JJ agreed with Mason CJ. "The implied undertaking is an endeavour to balance the intrusion into privacy by the compulsory production of documents necessary to do justice, with maintenance of privacy otherwise": Blanch v Deputy Commissioner of Taxation [2004] NSWCA 461 at [14], 58 ATR 113 at 116 per Giles JA (Hodgson and Ipp JJA agreeing). See also: Northbuild Constructions Pty Ltd v Discovery Beach Project Pty Ltd [2009] QCA 345 at [13]-[16], [2011] 1 Qd R 145 at 149-150 per McMurdo P (Muir JA agreeing); [2009] QCA 345 at [26]-[41], [2011] 1 Qd R 145 at 152-154 per Chesterman JA.
26 But, as stated by Mason CJ in Esso Australia, "once material is adduced in evidence in court proceedings it becomes part of the public domain, unless the court restrains publication of it". Once a document is adduced in evidence "… the open court principal (sic) necessarily overrides the right of privacy": Clone Pty Ltd v Players Pty Ltd (In Liquidation Receivers Appointed) [2012] SASC 12 at [181] per Kourakis J. Whether any "right of privacy" is overridden by adducing a document in evidence may be left to one side; any suggestion that confidentiality in documents produced pursuant to the compulsory processes of the Court and adduced in evidence is maintained is inconsistent with the document now being "in the public domain". For the confidentiality in such documents to be lost, however, a mere reference in open court to "… the nature of the document or its general subject matter will not suffice … [w]hat is required, as a minimum, is a disclosure of the substance of what is stated in the document": Forty Two International Pty Ltd v Barnes [2010] FCA 397 at [86] per Yates J.
27 It has also long been recognised, however, that a Court may release a party from the "implied undertaking". In discussing the circumstances in which such an order may be made, Brennan J in Esso Australia Resources said:
But such an undertaking "can, in appropriate circumstances, be released or modified by the court". That dispensing power is not freely exercised, but it will be exercised when special circumstances appear. In the Federal Court, special circumstances have been held to exist where "there is a special feature of the case which affords a reason for modifying or releasing the undertaking and [the feature] is not usually present". It is unnecessary to consider whether the dispensing power should be so broadly defined. It is relevant to note only that the obligation enforceable as an undertaking to the court in the case of a curial order is not unqualified: (1995) 183 CLR at 37.
More recently, in Liberty Funding Pty Ltd v Phoenix Capital Ltd [2005] FCAFC 3, 218 ALR 283 Branson, Sundberg and Allsop JJ expressed the principles to be applied as follows:
[31] In order to be released from the implied undertaking it has been said that a party in the position of the appellants must show "special circumstances": see, for example, Springfield Nominees Pty Ltd v Bridgelands Securities Ltd (1992) 38 FCR 217; 110 ALR 685. It is unnecessary to examine the authorities in this area in any detail. The parties were not in disagreement as to the legal principles. The notion of "special circumstances" does not require that some extraordinary factors must bear on the question before the discretion will be exercised. It is sufficient to say that, in all the circumstances, good reason must be shown why, contrary to the usual position, documents produced or information obtained in one piece of litigation should be used for the advantage of a party in another piece of litigation or for other non-litigious purposes. The discretion is a broad one and all the circumstances of the case must be examined. In Springfield Nominees, Wilcox J identified a number of considerations which may, depending upon the circumstances, be relevant to the exercise of the discretion. These were:
• the nature of the document;
• the circumstances under which the document came into existence;
• the attitude of the author of the document and any prejudice the author may sustain;
• whether the document pre-existed litigation or was created for that purpose and therefore expected to enter the public domain;
• the nature of the information in the document (in particular whether it contains personal data or commercially sensitive information);
• the circumstances in which the document came in to the hands of the applicant; and
• most importantly of all, the likely contribution of the document to achieving justice in the other proceeding.
This list of "considerations" is, obviously enough, not exhaustive. See also: James G Oberg (Sales) Pty Ltd v Oberg [2012] FCA 722 at [26]-[28], 292 ALR 673 at 678-679 per Edmonds J.
28 The "… public interest in discovering the truth so that justice may be done between the parties … is to be put into the scales against the public interest in preserving privacy and protecting confidential information": Riddick v Thames Board Mills Ltd [1977] QB 881 at 895. Lord Denning MR there also went on to observe:
… The public interest in privacy and confidence demands that this compulsion should not be pressed further than the course of justice requires. The courts should, therefore, not allow the other party - or anyone else - to use the documents for any ulterior or alien purpose. Otherwise the courts themselves would be doing injustice … : [1977] QB at 896.

29 In determining whether an order that a person be released from an "implied undertaking" should be made, it is not necessary for a Court to be satisfied that "any particular end of justice will be furthered" by the use of a particular document otherwise subject to the undertaking: Liberty Funding [2005] FCAFC 3 at [33], 218 ALR at 290. There in issue was whether an Affidavit which had been sworn for the purposes of a proceeding in this Court by an officer of the Respondent (Mr Jeffery) and filed but not read in that proceeding could be used in another proceeding in the Supreme Court of Victoria. In permitting the use of the Affidavit, Branson, Sundberg and Allsop JJ there further observed:
[33] … It should be recognised, of course, that any use in the Supreme Court proceedings will be under the restriction of a similar implied undertaking as to the use for the purposes of the proceedings in the Supreme Court. While the Jeffery affidavit might not have been intended to reach the public domain, given the width of the permitted purpose, information within the Jeffery affidavit was likely to reach the public domain if the matter was litigated. It is not said that the Jeffery affidavit contains personal data or commercially sensitive information. If it does, its use will be able to be protected both by the implied undertaking in the Supreme Court or by any necessary confidentiality orders. While it cannot be said categorically that any particular end of justice will be furthered by the use of the Jeffery affidavit in the Supreme Court proceedings, it seems to us appropriate that, to the extent that it deals with issues relevant to the resolution of the controversy in the Supreme Court, the Supreme Court should have available to it relevant material, including such an affidavit, sworn in an earlier proceeding, which may illuminate matters in the Supreme Court.
It is sufficient if a Court is satisfied that releasing a party from an "implied undertaking" opens up "avenues of inquiry": Springfield Nominees Pty Ltd v Bridgelands Securities Ltd (1992) 38 FCR 217 at 220. An application was there made to use a witness statement prepared but not used in one proceeding in a different proceeding. In that decision Wilcox J made clear that an order may be made releasing a party from the "implied undertaking" for the purpose of enabling the party to pursue "avenues of inquiry". His Honour observed (at 220):
… Counsel for Hongkong Bank mentioned the possibility of calling Mr Preston, using the statement as his evidence in chief. Whether that course will eventually commend itself, I do not know. But, even if Mr Preston is not called by either party, it is possible that the statement will prove useful in opening up avenues of inquiry. Without wishing to predict the most likely form of use, I think it probable that the statement will assist Hongkong Bank in relation to the Aetna claim. No doubt that is why Aetna opposes the order now sought.
Apprv'd: Forty Two International Pty Limited v Barnes [2010] FCA 397 at [72] per Yates J. His Honour notes Wilcox J's observation that "perhaps the most important consideration of all in considering whether leave should be granted is the likely contribution of the documents in achieving justice": [2010] FCA 397 at [98].
30 One consideration which is not expressly referred to in Liberty Funding is whether the document or documents disclose wrongdoing. Just as the "implied undertaking" is founded upon the need to protect the public interest in the administration of justice, it is also to be recognised that there is a public interest in disclosing (for example) criminal conduct.
31 In Australian Trade Commission v McMahon (1997) 73 FCR 211 the Commission sought to be released from an "implied undertaking" in respect to documents it had received during the course of proceedings before the Administrative Appeals Tribunal. The Commission sought to use those documents for "the purpose of investigating possible criminal conduct". In releasing the Commission from the "implied undertaking", Lehane J observed:
… The general principle is, no doubt, that a release of the implied undertaking will be given only if "special circumstances" are established: Crest Homes plc v Marks [1987] AC 829. Where an application for release is decided in contested proceedings, it seems that "special circumstances" will fairly readily be found where it is established that the use of documents discovered in a proceeding is reasonably required for the purpose of doing justice between the parties in other proceedings: see, for example, Holpitt Pty Ltd v Varimu Pty Ltd (1991) 29 FCR 576; Springfield Nominees Pty Ltd v Bridgelands Securities Ltd (1992) 38 FCR 217. Where an authority or person charged with the investigation of possible criminal conduct is a party to a proceeding and obtains, through for example documents discovered in the proceeding, information suggesting that criminal conduct, of a kind which the authority or person is charged to investigate, the public interest seems to me to require, in most cases at least, that permission be given to use the information for that purpose. Once that step is taken, it seems to me difficult to resist the next step: if the public interest accepts the necessity of secrecy in the conduct of criminal investigation, particularly as to the issue of warrants, an authority ought, in a proper case, to be able on ex parte application, without notice, to obtain leave to use for that purpose information the subject of a Harman implied undertaking.
His Honour there placed reliance upon the status of the person applying for a release as a person or authority "charged to investigate" criminal conduct.
32 In Rank Film Distributors Ltd v Video Information Centre (A Firm) [1982] AC 380 at 447 reference was made to the prospect of answers to interrogatories tending to show that a party has been "guilty of a serious offence" and to there being nothing "improper in his opponent reporting the matter to the criminal authorities with a view to prosecution". Notwithstanding these observations, a possibly more cautious and qualified approach has been embraced in Australia: Bailey v Australian Broadcasting Corporation [1995] 1 Qd R 476. Lee J there referred to the Rank Film decision and went on to conclude:
Does it then follow that a party who, through discovery, has come into possession of documents which disclose the commission of a criminal offence may, as of right, disclose them to the criminal authorities? In my opinion, it does not. To so conclude one would have to be able to say that in every case where the criminal law is infringed, the public interest in pursuing a prosecution in respect of that infringement outweighs the public interest in ensuring the integrity of the discovery process. However, the law is not so black and white. Indeed the plaintiff conceded that it will not be in every case where the criminal law is infringed that the Court will grant the leave sought: … The infringement may be of a trivial or inconsequential nature or the application for leave might be brought, not for the purpose of promoting the public interest, but rather out of malice or spite on the part of the applicant: … Moreover, the disclosure may have been brought about by circumstances in which the respondent was unable to claim a privilege otherwise open to him, e.g. through the compulsion of an Anton Pillar order. In such a case, the respondent may have a legitimate right to have the order set aside … and that is a factor which may render it unfair or unjust for the Court to grant the leave sought. All of the circumstances must be looked to in order to determine the nature and extent of the countervailing public interest raised: [1995] 1 Qd R at 486.
Where the Commonwealth is a party to a proceeding, it too - like any other party - requires the leave of the Court to use documents it has acquired through the compulsory processes of the Court for a "collateral or ulterior" purpose: Commonwealth v Temwood Holdings Pty Ltd [2001] WASC 282 at [41], 25 WAR 31 at 39 per Pullin J.
33 Other than to recognise that the notion of "special circumstances" does not require a party seeking to be released from the "implied undertaking" to establish "extraordinary factors", it would be neither wise nor possible to attempt any exhaustive list of what would constitute "special circumstances" in a given case.
34 Finally, it needs to be remembered that the onus lies upon those who seek to be released from the undertaking to use documents only for the purposes of the proceeding in which they were produced and that "discharging that onus and persuading the court to relax or waive those obligations is no easy matter": Northbuild Constructions [2009] QCA 345 at [13]; [2011] 1 Qd R 145 at 149-150 per McMurdo P.
35 It was assumed throughout that these were the same principles to be applied when considering r 20.03 of the Federal Court Rules 2011 (Cth). Indeed, the application of that rule was not referred to during the course of either written or oral submissions. That rule, however, provides as follows:
Undertakings or orders applying to documents
(1) If a document is read or referred to in open court in a way that discloses its contents, any express order or implied undertaking not to use the document except in relation to a particular proceeding no longer applies.
(2) However, a party, or a person to whom the document belongs, may apply to the Court for an order that the order or undertaking continue to apply to the document.
The current rule had as its predecessor O 15 r 18 of the now-repealed Federal Court Rules. The principles to be applied when interpreting this rule were reviewed by Edmonds J in ThoughtWeb Systems Pty Ltd v Loughnan (No 2) [2006] FCA 432 at [11]-[25], 230 ALR 515 at 521-523. There is no reason why the current rule should be interpreted in any different manner to the former O 15 r 18.
