in the fact of the obligation to disclose fully the relevant material to the Magistrate. He said that to be able to assess that, the applicants want access to all the information available to the first respondent
(2) if there was a "preconcerted plan" to alter the warrants as issued, the respondents would like to know that fact
(3) there is nothing in the expurgated version of the affidavit of the third respondent (bundle 49) that the applicants were at risk of prosecution, and there still has been no prosecution, and there is the prospect that the investigation was really that of the second respondent, with a possible improper purpose because it did not concern investigation of a relevant criminal activity, and so no prosecution may ever have been contemplated
(4) the material recording the process of the decision to apply for the warrant under s 3E of the Crimes Act rather than applying under the Act, touching upon the awareness of the respondents of the possible consequences of or benefits of those alternative possible sources of power to issue the warrants
(5) the nature of the information gathered in the investigation to disclose its sources, its content, and potential witnesses available to the first respondent and the information they have provided, and
(6) "regulatory issues" concerning the establishment of the joint task force, the role of the respondents in procuring and executing the warrants, the relationship between the respondents and regulatory agencies providing information to them, and the process by which the third respondent was seconded to the first respondent.
42 With the exception of the purpose in (4) above, it is in my view apparent that the applicants have no real foundation for the allegations made in the points of contention to which those categories of uses might relate. In the way it was expressed, category (2) was speculative only. Category (3) also can be no more than speculation. In respect of those two uses, there is no allegation in the points of claim concerning a state of mind on the part of any respondent to the effect asserted. Categories (1), (5) and (6) relate to whether information was withheld from the Magistrate upon which the warrant was sought: cp Propend Finance Pty Ltd v Commissioner of Australian Federal Police (1994) 72 A Crim R 278.
43 There is no issue about the obligation of the first and third respondents to have disclosed to the magistrate from whom the warrant was sought all material factors that may have affected the decision to issue the warrant: see per Davies J in Propend (above) at 280-281 and the authorities referred to in those reasons. In that case, there was an application to set aside notices to produce all documents relating to an investigation held at the time when the application for the warrants was sought. The mere allegation that there had been a failure to disclose all relevant material was insufficient to enhance the claim to production beyond a "fishing" request (at 284), and the notices to produce were set aside. Davies J did not have to determine whether they should not be produced on the ground of public interest immunity.
44 In the present circumstances, the documents in issue have been discovered pursuant to the order made on 21 May 1999. But there is nothing to indicate that, with the exception mentioned, the applicants have any foundation in fact for the allegation that proper disclosure was not made to the magistrate. No particular has been given of any such foundation. No affidavit evidence identifies any such foundation. Having briefly examined the sworn application for the warrant (bundle 49); as Davies J concluded upon a similar process in Propend, I did not identify any material further which ought to have been disclosed to the magistrate and which was not disclosed.
45 Those considerations, in my judgment, must be put into the balance when addressing the present issue. If there were a clear and serious issue raised about a particular type of information not brought to the magistrate's attention, or about particular material not brought to the magistrate's attention, the significance of what was disclosed and perhaps the existence and contents of documents relating to that type of information or material would be greater. The public interest in ensuring a just outcome for the proceedings in those circumstances would require significant weight to be given in favour of disclosure. Where the allegation is not particularised, and seems to be essentially fishing, the administration of justice does not demand so strongly disclosure of the documents.
46 On the other hand, disclosure of the material in issue would clearly be injurious to the public interest. The person taking the objection, Mr Irwin, is a member of the first respondent. He has inspected the documents. He has explained the reasons for the objection. I accept those reasons. They are not reasons which in all respects are of great significance. For instance, the extent to which cooperation with other governmental bodies might be jeopardised by their disclosure is, in my view, not of particular moment bearing in mind the first respondent's powers under s 19A of the Act. On the other hand, the disclosure of the identity of informants may have grave adverse consequences to the public interest in the identification, investigation and prosecution of criminals: Sankey at 61; Rogers v Home Secretary [1973] AC 388. One well recognised category of documents in respect of which public interest immunity has been acknowledged is documents disclosing methods of police investigation and plans in relation to ongoing police investigations: eg. Young v Quin at 495; Beneficial Finance Corporation Ltd v Commissioner of Australian Federal Police (1991) 51 A Crim R 423 at 436-438 and on appeal (1991) 31 FCR 523. Those considerations find statutory expression in s 130(4) of the Evidence Act.
47 I am satisfied in respect of all the bundles of documents to which objection against production is taken, that there is a firm public interest in their continued non-disclosure, although the weight to be attributed to each of the bundles in the weighing process is not equal. As I have indicated above, I do not consider that the interests of justice require that generally the documents in issue should be disclosed, notwithstanding their discovery by the first and third respondents. Their significance to the applicants is speculative only. There is nothing of substance to suggest that their disclosure is required to serve the administration of justice in the particular circumstances. I am firmly of the view that the claim for public interest immunity is made out.
48 I noted above one area in which the public interest in the administration of justice might nevertheless require disclosure of certain of the documents in the bundles. That is material recording the process of the decision to apply for the warrant under s 3E of the Crimes Act rather than under the Act. I make it clear that the documents to which I am referring are those which address the topic of how to apply for the warrant, including such matters as who should make the application, the various statutory powers potentially available to procure the warrant, the categories of person or persons to whom the application might be made, the selection of the process of making the application under s 3E of the Crimes Act, and the selection of the person or category of persons to whom that application was made. There are clear grounds specified in the points of contention why the warrant was not properly sought under s 3E of the Crimes Act. Those grounds are described in more detail in the next part of these reasons, when addressing the claim that the claim for public interest immunity must fail because the first and third respondents acted illegally in procuring the warrant. I am not satisfied by Mr Irwin's affidavit that it is necessary in the public interest that any such document should not be disclosed. He has not specifically identified any such documents or explained why they, in particular, should not be disclosed. There is no reason to think that such documents will contain confidential information relating to the investigations of the joint task force, or alert persons under investigation of proposed ongoing investigations. It is only in a limited way that they will disclose the methodology of the first respondent, and on the other hand it is a methodology about which the applicants have made detailed allegations and which, if the applicants are correct, may reveal improper conduct by the first and third respondents. There is also no reason to think that particular documents will disclose sources of information to the first respondent, or the nature of information procured by it. It may be that there are no such documents. I do not know. Short of calling for, and examining, all the documents in issue, it is not possible for the Court to determine that question for itself. I do not think that that is an appropriate course.
49 I accordingly propose to direct that the first and third respondents disclose to the applicants any documents of the character identified. That will require the bundles, or at least some of them, to be re-examined. I propose to give leave to the first and third respondents to mask in an appropriate way the contents of any such documents which do not relate to the topics I have referred to, if it is feared that the disclosure of the full document may have adverse consequences to the public interest. That leave is intended to relate only to the parts of such documents which do not touch on the topics described above. If the applicants nevertheless claim to be entitled to inspect any part of such a document, which has been masked, it may then be necessary for the Court to examine it to determine whether its full contents should be disclosed.
(e) Has illegality caused the claim to public interest immunity to be lost?
50 In A v Hayden (1984) 156 CLR 532, the High Court refused to restrain the Commonwealth from disclosing to the Commissioner of Police for Victoria the identity of officers of the Australian Secret Intelligence Service ("ASIS") who were alleged to have committed criminal offences in the course of a security training exercise. In the course of their reasons, some members of the Court considered and explained the pithy observation of Wood V.C. in Gartside v Outram (1856) 26 L.J. Ch 113 at 114 that "there is no confidence as to the disclosure of iniquity"; see per Gibbs CJ at 545, and Wilson and Dawson JJ at 572.
51 That case was relied upon by the applicants for the contention that, because the claim for public interest immunity has been made "in circumstances where there has been demonstrable illegality" the claim in its entirety must be rejected.
52 I do not consider that that decision stands for such a broad proposition. The claim to non-disclosure was made by the ASIS officers themselves, based upon an alleged enforceable obligation, at least partly arising under contract, not to disclose their identities. The Commonwealth wished to disclose those names; it did not assert that public interest immunity precluded that course. The outcome was that the obligation of confidentiality under the respective contracts of employment was unenforceable (per Mason, Murphy, Wilson, Brennan, Deane and Dawson JJ).
53 I agree that there is a strong public interest in the disclosure of iniquity (per Sheppard J in Allied Mills Industries Pty Ltd v Trade Practices Commission (1981) 55 FLR 160 at 166), but as Gibbs CJ said in Hayden at 545-546 there is nevertheless a balancing process, albeit one heavily weighted in favour of disclosure in the case of serious crime; see also the observations of Mason J at 559-560, and of Wilson and Dawson JJ at 577. It was not contended that the documents in issue could not be the subject of a claim to non-disclosure by reason of the circumstances in which they came into existence. The argument was that whatever public interest existing in their non-disclosure was lost by the illegality alleged. It is, as the applicants acknowledge, incumbent upon them to demonstrate a clear prima facie case of illegality: see Commissioner of Australian Federal Police v Propend Finance Pty Ltd (1997) 188 CLR 501 per Brennan CJ at 514, Toohey J at 532, Gaudron J at 546, McHugh J at 556, Gummow J at 573-574 and Kirby J at 591-592.
54 It also follows from Propend, in my view, that illegality will displace the privilege only in respect of the particular illegality alleged: see eg. per Gaudron J at 545, McHugh J at 556, and Gummow J at 563. Indeed, it would be surprising if it were otherwise. The discoverable documents in a matter involving a prolonged investigation may extend over a period of years, and there may be very sound reasons which the public interest is best served by the non-disclosure of those documents. If, in the course of that investigation, an act of illegality occurred (perhaps by accident or through ignorance) in the investigation, it would not follow that the public interest in the non-disclosure of all those documents would reverse. It may do so in respect of the part of those documents which involve the illegality.
55 The applicants submit that, because the third respondent was seconded to the first respondent, his powers under the Police Act 1952 (SA) and under any other law are suspended: ss 19B(3) and 27 of the Police Act. Then, it is put, his entitlement to apply for a warrant under the Crimes Act is lost because, by virtue of that suspension, he is no longer a "constable" under s 3 of the Crimes Act and so is not entitled to apply for or execute the warrant: ss 3C and 3E of the Crimes Act. Those requirements must be strictly adhered to: George v Rockett (1990) 170 CLR 104 at 110-111. The applicants also contend that there is evidence of the alteration or deletion of the name of the issuing magistrate from the warrant, and of the name of the third respondent, although the first and third respondents rely upon ss 3(h)(5) and 3E(5) of the Crimes Act for such alterations as were made.
56 I am satisfied that the applicants have made out a prima facie case of illegality in the third respondent applying for and executing the warrant. I do not, however, consider that that conclusion destroys all the claims for public interest immunity made by Mr Irwin. I have ruled that the claim for public interest immunity does not protect from disclosure documents which relate to the process of deciding to apply for the warrant. It is that category of documents which, once produced for inspection, may reveal how and why s 3E of the Crimes Act came to be used to procure the warrant. I am not, however, persuaded that any of the respondents were aware of the alleged illegality. The documents to be produced may disclose that to have been the case. If it were, the consequence may be that documents procured in the execution of the warrant, or other documents, might also be vulnerable to disclosure although at present I have ruled that public interest immunity protects them from disclosure. As I am not presently persuaded that the alleged wrongdoing (if established) was deliberate, or prima facie is shown to have been deliberate, I consider the appropriate order is to direct disclosure only of those documents which may tend to expose any such illegality. I do not consider that the authorities relied upon by the applicants oblige me to make any more extensive order at this point.
57 Consequently, in the light of those conclusions, presently I do not propose to make any additional order for the disclosure of documents in respect of which a claim for non-disclosure for public interest immunity has been made.
