Consideration
26 As noted above, in support of his claims of public interest immunity, the IGADF relies, inter alia, on the same open and confidential affidavits of Mr Gaynor sworn on 20 September 2021, as were relied on in Roberts-Smith (No 24). That material from the open affidavit is summarised at [12]-[28]. As I observed, although it was inappropriate to recite the evidence in the confidential affidavit, it sufficed to say that it added weight to the IGADF's claim for public interest immunity. I accepted his evidence in the open and confidential affidavits and concluded, inter alia, that significant weight can be attached to the opinions he expressed about the impact of disclosure of the information sought: at [62]-[63]. Those conclusions apply in this application.
27 In Roberts Smith (No 24), the orders made were interlocutory, of a substantial nature, and made after a contested hearing and in contemplation that the order will operate until the final disposition of the matter. The document sought in respect to Person 24 falls squarely within those orders. As such, a material change of circumstances is relied on by the applicant to contend the ruling should be reconsidered in respect to the documents sought.
28 The applicant's contention that in Roberts Smith (No 24) at [75] I held out that the ruling could be reconsidered in the event of a change of circumstances involves a misreading of the passage. That said, it is of no moment to the resolution of this application. In any event, the IGADF accepted that there has been a material change since Roberts-Smith (No 24) such as to permit that ruling to be revisited in respect to the material sought in relation to Person 24.
29 The IGADF also properly accepted that in that circumstance, there was a relevant public interest consideration on each side of the equation (that harm would be done by disclosure of the documents sought and the proper administration of justice would be frustrated or impaired if the documents were withheld), and that the balancing exercise described in Alister v The Queen [1984] HCA 85; (1984) 154 CLR 404 (Alister) is to be performed.
30 The observations made in Roberts-Smith (No 24) at [65] ff in respect to the public interest considerations that arose in connection with the documents sought from the IGADF in that matter, similarly apply in this application. I take those matters into account. It is unnecessary to repeat them here.
31 It is appropriate to add the following observations.
32 First, this application is based on the evidence given by Person 24 at the hearing in relation to Whiskey 108 which is said to be inconsistent with his version as summarised in the applicant's PAP notice. The nature of the PAP notice is described by Colvin J in Roberts-Smith v Fairfax Media Publications Pty Limited (No 6) [2020] FCA 1285 (Roberts-Smith (No 6)) at [60]-[61], recited in Roberts-Smith (No 14) at [79]. The applicant repeatedly characterised Person 24's evidence as false. That characterisation does not assist the argument, as an inconsistency in a witness' evidence does not, in and of itself, necessarily carry that connotation. Suffice to say, I approach this application on the basis that, on the evidence before me, prima facie there is an inconsistency between the evidence of Person 24 and what is recorded in the applicant's PAP notice in respect to Person 24's evidence of witnessing the applicant murder an unarmed PUC during a mission involving a compound known as Whisky 108 on 12 April 2009. I note that the respondents allege in their defence of truth that the applicant murdered a PUC at Whiskey 108: Second Further Amended Defence to Statement of Claim at [40]-[52]. This is a topic of significance. The IGADF did not submit otherwise.
33 Second, the material sought in Roberts-Smith (No 24), was directed to prior statements of current or former SOCOMD witnesses to be called by the respondents, because of the respondents' reliance on the defence of truth. The potential relevance of this material was directed to the credit of the witnesses, in the form of prior inconsistent statements. That eventuality was taken into account in the weighing process in Roberts-Smith (No 24) at [75]-[79]. As the IGADF submitted, this application is based on a factual matter foreseen and considered in that judgment. That the foreseen circumstance eventuated does not, without more, establish there has been a material change of circumstance such as to reopen the ruling. However, this individual application is now advanced on a more concrete foundation, as the applicant points to evidence of an inconsistency, and on a matter of significance. In a context where it is accepted by the IGADF that there is a material change of circumstance, the nature of the topic on which the inconsistency relates and the extent or significance of it, must be part of the weighing process. That must be so given the nature of the balancing exercise being conducted. The topic and the extent of the alleged inconsistency impacts on the Court's assessment on whether the proper administration of justice might be frustrated or impaired if the document was withheld. I note in this context that the applicant also relies on the fact that Person 24 has given evidence that he told somebody in 2017 or 2018 about this account of the events.
34 Third, in an attempt to distinguish these circumstances from those described in Roberts-Smith (No 24) at [82] and to compare them favourably to those of the Afghan witnesses who gave evidence without subpoena (addressed in Roberts-Smith (No 14)), the applicant submitted that although Person 24 was subpoenaed to give evidence, he has given evidence that he willingly came to Court to back up his friends and he was "happy" to do so. That, on the evidence before me, at the very least, rather overstates his evidence. On any scenario he was subpoenaed to give evidence without his knowledge, as is apparent from Roberts-Smith (No 12). Although, as the applicant submitted, he did not apply to be excused from doing so by having the subpoena set aside, that does not support a contention that the witness is willing or happy to give evidence. There are limited circumstances in which a witness can be excused from giving evidence, and simply not wishing to do so, would be insufficient. Moreover, this submission fails to grapple with the nature of the broader public interest considerations which arise from disclosure of material of the nature sought. The submission fails to recognise that there are a number of matters which distinguished this matter from the circumstances considered in respect to the Afghan witnesses: see for example Roberts-Smith (No 24) at [80].
35 Fourth, the IGADF correctly submitted that there is evidence other than that given by Person 24 which is directed to Whiskey 108 and that there have been a substantial number of documents provided to the respondents, as a result of subpoenas being issued, in respect to that mission. The allegations as to the events on 12 April 2009 at Whiskey 108 will be considered in light of all the evidence led on the topic. Also, of course, any assessment of a witness' evidence (including their credibility) is to be considered in the context of the whole of the evidence. Person 24's evidence will not be considered in a vacuum. However, the submission that the applicant has been able to challenge Person 24's evidence on this topic, fails to recognise that putting to a witness that his evidence is false, if denied, does not, without more, advance the applicant's case. I appreciate in this context that the IGADF submit the rule in Browne v Dunn (1893) 6 R. 67 (H.L) does not require that a witness "be cross-examined on every point", but only that he or she "be given an opportunity to comment on or explain some matter about which the opposing party intends to make comment", citing Cross On Evidence (12th ed, 2020) at [17440]. However, it may be that statements in the PAP notice need to be put into their proper context, the summary may be incomplete or inaccurate, or the witness, if asked, may provide an explanation. That said, I accept the applicant's submission that the material sought is potentially significant to an assessment of the credit of Person 24 given the nature of his evidence and the topic on which it was given.
36 Fifth, the applicant repeatedly submitted, as he has in previous applications, that the only reason the witness is giving evidence is because the PAP notice was provided to the respondents (in a redacted form) as a result of the ruling by Colvin J in Roberts-Smith (No 6) and Roberts-Smith (No 8). For the reasons previously expressed in Roberts-Smith (No 24) at [69], and in the confidential reasons at [14], that does not assist with the resolution of this application. It is to focus on the wrong question. That said, as noted in Roberts-Smith (No 24) at [67], the fact that the PAP notice was provided is part of the factual context in which this application arises.
37 Sixth, the provision of the material sought will, as the IGADF submitted, result in an information asymmetry between the parties, in that the respondents have not, and cannot, have access to material relating to the applicant and his witnesses: see on this issue, Roberts-Smith (No 24) at [53]-[55] and [77]-[78]. However, it is important to recall that the Subpoena relates to only one witness, and has arisen in very particular factual circumstances. Any decision in relation to this witness can have no broader application, for example, in respect to the other SOCOMD witnesses. So much was accepted by the applicant in his submissions. The applicant submitted, relying on the affidavit of Mr Bartlett, that the respondents intended to lead evidence consistent with the content of the PAP notice and that the applicant had not been provided with any advance notice of the evidence that was ultimately given by Person 24. So much may be accepted, although I note that in Roberts-Smith (No 12), the ruling in which Besanko J granted the respondents' application for leave to issue subpoenas to certain witnesses, including Person 24, to give evidence, his Honour at [54] did not order outlines of evidence to be filed on the basis that the PAP notice provided sufficient notice to the applicant of those witnesses' evidence. In any case, it is unclear how that impacts on this application, other than to indicate that the applicant had a lack of notice of the detail of the evidence ultimately given by Person 24 at the hearing. The respondents have called Person 24 in support of their case, and regardless of any issue of knowledge on their part as to what the contents of his evidence would be before he was called, they have material in the form of the PAP notice which, in part, is prima facie inconsistent. The respondents' reliance on his evidence must be considered in that context. The respondents did not raise any issue of information asymmetry as a consideration in this application, which is to be contrasted to the submissions made by the respondents in respect to Roberts-Smith (No 24).
38 Seventh, the applicant's submission as to the harm done by the release of the document sought largely fails to address the broader public policy considerations referred to in Roberts Smith (No 24) at [97]-[98], but focusses almost entirely on his case. That said, it may be accepted that what is sought is much more limited, relating to one person and the events at one location on a specific day, and arises in a very particular factual context, which did not exist at the time Roberts-Smith (No 24) was decided. The public policy issues referred to in [97] and [98] are to be considered in that light. On the other hand, the IGADF's submissions focussed on the broader policy issues that arose at the time of Roberts-Smith (No 24), and while plainly still relevant, the weight to be attached to those policy concerns must now be considered in the context of this different factual context.
39 I have addressed Mr Gaynor's evidence as to the effectiveness of the NSI orders in minimising any potential harm caused by disclosure in previous judgments: see for example: Roberts-Smith (No 14) at [92]; Roberts-Smith (No 24) at [95]. Again, that must be considered in light of this case being a much more limited application. The IGADF made submissions expressing concern about the number and type of people who could have access to a document if one is released. In that regard, the applicant submitted that he would consent to amendments to the NSI orders which would have the effect of limiting access to any document produced, to the applicant's lawyers and any cross-examination relating to it would only occur in closed court. Irrespective of the terms of the NSI orders being amended, the applicant's counsel has given an undertaking that if a document is ordered to be produced, access would be limited to the applicant's lawyers and any cross-examination relating to it would only occur in closed court. The applicant himself would not have access to the document. Giving an undertaking to the Court is a serious matter and, therefore, I act on that basis. The IGADF also made submissions as to the difficulty it foresaw of the parties to the proceedings agreeing to amendments to the NSI orders to accommodate this document if it is required to be produced, given they have different interests. As just explained, the applicant has made his position clear. Given the circumstances, it is difficult to see a basis the respondents would not agree to that proposed course.
40 The document sought relates potentially to the credibility of Person 24. Denying access to the document sought would likely deprive the applicant of the opportunity to challenge Person 24's evidence on the basis that, on the material before this Court, he has prima facie made a prior inconsistent statement on a significant aspect of his evidence. In that context it would likely deprive the trial judge of an opportunity of making an informed decision as to the assessment of Person 24's credibility.
41 During oral submissions, the applicant described his earlier application the subject of Roberts-Smith (No 24) as a "fishing expedition", although that was not the description then proffered. It is not an inapt description. That subpoena was issued relating to 12 current or former SOCOMD persons who were expected to be called as witnesses by the respondents, in anticipation of them giving evidence. Each case must be considered on its own facts. As explained, this application arises in a very different factual context to that which existed at the time of Roberts-Smith (No 24). In the present matter, the applicant has relied on the evidence given by Person 24 in the hearing and on material in the PAP notice which prima facie is inconsistent with an aspect of the evidence, on a significant topic. The material sought is limited to the events on 12 April 2009 at Whiskey 108. The probative value of the material in assessing Person 24's credibility may be high. The credibility of the witness will be a matter for the trial judge to assess in light of all the evidence, at the end of the hearing. It is sufficient to say at this stage that, given the topic of Person 24's evidence which is sought to be relied on by the respondents, and the nature of the alleged inconsistency, the material sought by the Subpoena may affect the assessment of the credit of this witness.
42 As noted above, some submissions were made in closed court due to the application of the NSI orders to certain material, and I have addressed aspects of those submissions in confidential reasons which supplement this judgment. Those matters have been considered in the balancing process. Balancing all the considerations in the very particular circumstances of this case, I am satisfied that there should be production of the document. This conclusion has no broader application. Rather, and to be clear, this conclusion would be otherwise but for the very particular factual circumstances of this application. The conclusion in respect to the documents in respect to all other witnesses to which Roberts-Smith (No 24) relates, still holds. As noted above, the applicant did not contend otherwise.
