The Heller Documents
I have not inspected the Heller documents and, for reasons which will appear, I think it is unnecessary at this stage that I do so. There is no controversy about their general nature or the circumstances in which they came into existence. During 1994 the ASC conducted, on a referral from the Australian Stock Exchange, an investigation of suspected contraventions of the provisions of the Corporations Law concerning insider trading. The suspected contraventions related to trading, during November 1993, in shares of the fifth respondent. The investigation has long since concluded. The dealings investigated by the ASC took place close to the time when the first and fifth respondents entered into a series of transactions by which, among other things, the first respondent took up shares in the fifth respondent and transferred to the fifth respondent all the issued shares of a company entitled to take up a satellite pay television licence; the first respondent had, very shortly beforehand, acquired the shares in that company from their previous holders, principal among whom was the applicant. The transactions between the applicant and the first respondent and between the first respondent and the fifth respondent are of central importance to issues in this proceeding. Mr Heller was one of the officers of the first respondent principally involved in negotiating and completing those transactions.
In the course of its investigation, the ASC sought information from Mr Heller. Mr Heller provided information voluntarily, not under compulsion. He did so at an interview with officers of the ASC on 28 July 1994 and he provided further information in a nine page letter to the ASC dated 9 September 1994, by way of response to a series of detailed written questions from the ASC. The letter commences with a statement, in a series of numbered paragraphs, of the basis on which Mr Heller provided the information in it, followed by a suggestion that the ASC's retention of the letter "will be acceptance of the basis of our reply". The third of the numbered paragraphs is as follows:
The information in this response is confidential and commercially sensitive. The ASC will hold it in the strictest confidence and will not make copies of the whole or any part of it and will not release or disclose the contents of the whole or any part of it to anyone outside the ASC. The ASC agrees that this letter is not subject to any power of disclosure the ASC may have under legislation (including section 25 of the ASC Law) or otherwise.
The Heller documents, or copies of them, have not been produced on discovery: neither the first respondent nor Mr Heller has a copy of them. The letter of 9 September 1994 has been produced. Mr Heller (through his solicitors, who are also the solicitors for the first and second respondents) has notified the ASC that he objects to the release of the Heller documents on the basis that the information which they record was given to the ASC in confidence. Mr Riordan gave evidence that if Mr Heller consented to the release of the Heller documents the ASC would not object to their being made available for inspection. Since, however, Mr Heller does not consent, the ASC makes a claim of public interest immunity. Mr Riordan, in his affidavit, puts the claim of the ASC as follows:
For its part, the ASC seeks to uphold a claim of public interest immunity on this material, on the basis that the information was given to it on a voluntary basis, was full and frank and of significant importance for the purpose of its investigation. The ASC is concerned that, should information so received be produced in Court, it will adversely affect the willingness of persons to give information on a voluntary basis.
The principles relating to public interest immunity, as they emerge from the decisions of the High Court in Sankey v Whitlam (1978) 142 CLR 1 and Alister v The Queen (1984) 154 CLR 404, have been considered in a number of cases involving the ASC and its predecessor, particularly, by the Full Court of this Court, in Zarro v Australian Securities Commission (1992) 36 FCR 40 and Somerville v Australian Securities Commission (1995) 60 FCR 319. In Spargos Mining NL v Standard Chartered Aust. Ltd (No. 1) (1989) 1 ACSR 311, McLelland J said, at 312:
In my opinion, documents within the possession of the Commission of a confidential nature recording information received by the Commission relating to possible offences or irregularities, or recording information received in the course of the investigation of possible offences or irregularities, including the identity of informants, and confidential documents recording the actual or possible course of such investigations or particulars of available or potentially available evidence, are in the public interest prima facie immune from compulsory disclosure, on the basis that such disclosure would be likely to seriously impede the ability of the Commission to fulfil its function of effectively investigating possible offences......and in appropriate cases instituting and prosecuting criminal or civil proceedings in the public interest. ......
Such immunity as I have described is, however, not absolute. It may in particular circumstances have to yield to the requirements of justice.
In a proper case the court is required to perform what has been called a "balancing exercise" in which it considers the nature of the injury to the public interest which would be involved in disclosure as against the forensic importance of the documents in the circumstances of the particular litigation, and the nature of that litigation: ....
Those are, in substance, the principles which the Full Court has applied: see particularly Somerville at 331, 353, 354. In Somerville at 331, Lockhart J described the process to be undertaken by the court as follows:
Courts will not order the production of documents, although relevant and otherwise admissible, if it would be injurious to the public interest to disclose them and their contents. The Court must consider two conflicting aspects of the public interest: first, whether harm would be done by the production of the documents and secondly, whether it would impair the administration of justice if the documents were withheld. The Court must then engage in a balancing exercise and determine which of these elements predominates.
There is no doubt that there is a public interest in, as counsel for the first respondent put it, upholding the confidence of people who visit the ASC and give it information voluntarily in order to assist the ASC in its investigations. That is because the ability of the ASC to perform its investigative functions effectively may be impaired if people are deterred from providing information voluntarily on what they believe to be a confidential basis. There is no evidence in this case that Mr Heller provided information, in the interview, on the express basis that he did so in confidence. It was suggested, however, and I am prepared to accept, that it may be inferred from the terms of the subsequent letter that Mr Heller's understanding of the process was that information which he provided would be treated as confidential. The authorities make it plain, however, that that is not the end of the matter and that there is a public interest also in the proper administration of justice to be weighed in the balance.
The cumulative circumstances of this case are somewhat unusual. It is known that Mr Heller provided information to the ASC; significant information which he provided, in the form of the letter to the ASC, is already available to the applicant; it may be inferred that what Mr Heller said in the interview prompted the particular questions put to him by the ASC, to which in turn the September letter was a response. The matters concerning the fifth respondent in which Mr Heller was involved, on behalf of the first respondent, before and during the period covered by the investigation are of considerable importance in relation to the issues in this proceeding. The investigation itself concluded a considerable time ago, did not involve any contravention, suspected or alleged, against Mr Heller or the first respondent and resulted in no conclusion adverse to either. Mr Heller's account of the events in question, given in 1994, is, given the part played by him in the dealings with both the applicant and the fifth respondent, plainly of relevance in the proceeding; and part of that account, given in the letter, has already been disclosed. In all those circumstances, in my view, the disclosure of the Heller documents to the parties to this proceeding is likely to have only a slight deterrent effect, if any, on those who might in future contemplate voluntarily giving information to the ASC; on the other hand, the public interest in the proper administration of justice strongly suggests in the circumstances that the Heller documents should be disclosed.
Mr Riordan, as well as giving evidence, appeared for the ASC and made submissions on its behalf. He informed me that the ASC's concern included the possible effect of an order permitting inspection on the way in which large commercial legal firms would approach requests from the ASC for voluntary assistance of their clients. The suggestion was that their readiness to provide (or, presumably, advise clients to provide) assistance voluntarily would diminish. The answer to that submission is, I think, again that the circumstances of this case, as I have described them, are unusual and special: my decision does not - and could not - cast any doubt on the existence of a prima facie immunity which has authoritatively been held to exist, but is simply that, in the particular circumstances, the public interest in the proper administration of justice prevails.
For those reasons, I overrule the ASC's claim of public interest immunity in relation to the Heller documents; they may be inspected by the parties.
