The Privilege against Self-Incrimination
23 Section 128 of the Evidence Act relevantly provides:
(1) This section applies if a witness objects to giving particular evidence, or evidence on a particular matter, on the ground that the evidence may tend to prove that the witness:
(a) has committed an offence against or arising under an Australian law or a law of a foreign country; or
(b) is liable to a civil penalty.
(2) The court must determine whether or not there are reasonable grounds for the objection.
(3) Subject to subsection (4), if the court determines that there are reasonable grounds for the objection, the court is not to require the witness to give the evidence, and is to inform the witness:
(a) that the witness need not give the evidence unless required by the court to do so under subsection (4); and
(b) that the court will give a certificate under this section if:
(i) the witness willingly gives the evidence without being required to do so under subsection (4); or
(ii) the witness gives the evidence after being required to do so under subsection (4); and
(c) of the effect of such a certificate.
(4) The court may require the witness to give the evidence if the court is satisfied that:
(a) the evidence does not tend to prove that the witness has committed an offence against or arising under, or is liable to a civil penalty under, a law of a foreign country; and
(b) the interests of justice require that the witness give the evidence.
…
(7) In any proceeding in an Australian court:
(a) evidence given by a person in respect of which a certificate under this section has been given; and
(b) evidence of any information, document or thing obtained as a direct or indirect consequence of the person having given evidence;
cannot be used against the person. However, this does not apply to a criminal proceeding in respect of the falsity of the evidence. …
24 Section 128(7) refers to an Australian court. That term is defined in the Dictionary to the Evidence Act as follows:
Australian court means:
(a) the High Court; or
(b) a court exercising federal jurisdiction; or
(c) a court of a State or Territory; or
(d) a judge, justice or arbitrator under an Australian law; or
(e) a person or body authorised by an Australian law, or by consent of parties, to hear, receive and examine evidence; or
(f) a person or body that, in exercising a function under an Australian law, is required to apply the laws of evidence.
25 In relation to both questions, Person 14's counsel submitted that, as he put it, both limbs of s 128(1) were engaged. Person 14's counsel relied on the following as bringing the case within s 128(1) and (2): (1) s 60(1) (defence member doing an act likely to bring discredit on the Defence Force) and s 29 (defence member failing to comply with a lawful general order which applies to the defence member) of the Defence Force Discipline Act 1982 (Cth); (2) s 70(1) of the Crimes Act 1914 (Cth) (disclosure by a Commonwealth officer of information received as an officer which the officer is under a duty not to disclose); and (3) s 122.4 of the Schedule to the Criminal Code Act 1995 (Cth) (unauthorised disclosure of information by Commonwealth officers). As to s 29(1) of the Defence Force Discipline Act, counsel for Person 14 referred to the Media and Communication Policy dated 15 July 2019 (clauses 3.2, 3.4, 3.5, 3.8, 4.6, 4.10, 4.11, 4.13, 5.12, 5.13 and 5.20) and Defence Instructions (General) dated 5 October 2007 (now cancelled) (clauses 12, 24 and 33).
26 The assessment of whether there are reasonable grounds for the objection is to be made having regard to all the circumstances. The witness is not required to disclose the material which the witness contends is incriminatory. In Ross v Internet Wines Pty Ltd [2004] NSWCA 195; (2004) 60 NSWLR 436, Giles JA (with whom Spigelman CJ and McColl JA agreed) said (at [101]-[102]):
101 In my opinion, the appellant's position should be upheld. The appellant was obliged to deliver a disclosure affidavit to the judge's associate, and it would be "inspected" by the judge at a hearing. I will assume, without deciding, that the appellant would thereby be a witness for the purposes of s 128(1). But by compliance with the obligation his fundamental common law right would already be infringed. In order to have his claim to privilege determined, he would have to disclose the material which he said was incriminatory and should not be disclosed. There would be offence to the principle underlying the observation of Lord Denning MR in Rio Tinto Zinc Corporation v Westinghouse Electric Corporation [1978] AC 547 at 574, that a witness "should not be compelled to go into detail - because that may involve his disclosing the very matter to which he takes objection". See also Accident Insurance Mutual Holdings Ltd v McFadden (at 447 [90] supra) stating that the court will determine a claim to privilege "without requiring the witness fully to explain how the effect would be produced, for if it were necessary, the protection which the rule is designed to afford the witness would be annihilated".
102 If the information in the disclosure affidavit tended to incriminate the appellant, he was imperilled because he had brought into existence an incriminatory document: the respondents' acceptance of infringement if it had been found that whatever was in the disclosure affidavit would infringe the appellant's privilege recognised the peril. The respondents submitted that the appellant was no more imperilled than a person who was ordered by subpoena to produce a document at court, the order being good and the claim to privilege being made at the time appointed for production. But that is different. The appellant was compelled to make a document which did not previously exist, and no longer had control of the document after its delivery to the judge's associate: all this without any s 128 certificate.
(See also Field v Kingston [2018] FamCAFC 145; (2018) 337 FLR 1 at [27].)
27 I was satisfied that there were reasonable grounds for Person 14's objection.
28 I then provided the information in s 128(3) to the witness and the witness indicated that he was not willing to give the evidence.
29 The applicant indicated that he pressed the question and ultimately he accepted that he had the onus of establishing the matters in s 128(4). That is correct (Gedeon v The Queen [2013] NSWCCA 257; (2013) 280 FLR 275 (Gedeon) at [285] per Bathurst CJ). I heard submissions on s 128(4) and determined that, although satisfied of the matter in s 128(4)(a), that is to say, that the evidence did not tend to prove that Person 14 had committed an offence against or arising under, or was liable to a civil penalty under, a law of a foreign country, I was not satisfied that the interests of justice required that the witness give the evidence within s 128(4)(b). As to s 128(4)(a), the alleged offences or acts giving rise to a civil penalty were, if committed, committed in Australia, involved Australian law and related to Australian Defence Force members or Commonwealth officers.
30 Before addressing s 128(4)(b), I should make it clear that there are two aspects or stages of the evidence that must be recognised. First, there is the effect on the Court's assessment of Person 14's credibility and reliability of the incriminating evidence, that is, evidence that tends to prove that he has committed an offence against or arising under an Australian law or is liable to a civil penalty. This is the effect of the incriminating conduct on credibility. Although it was not treated as irrelevant by the applicant in his submissions in relation to the first question, it was not the main focus of his submissions. The main focus of the applicant's submissions in terms of his case as to the importance of the evidence (one of the factors relevant to whether I am satisfied that the interests of justice require that the witness give the evidence) was that the evidence of Person 14 will or may lead to a situation where the applicant is able to test Person 14's account in Court with an account or accounts he has given previously to journalists. As will by now be clear, this identification of the importance of the evidence intersects with circumstances relevant to the respondents' objection based on s 126K of the Evidence Act.
31 Section 128(4)(b) requires the Court to be satisfied that the interests of justice require that the witness give the evidence. This is a high standard and higher than if the paragraph had provided that the interests of justice favour that the witness give the evidence. This was noted by Bathurst CJ in Gedeon as follows (at [286]):
Second, the requisite standard provided for in s 128(4)(b) of the Evidence Act is that the interests of justice require admission of the evidence. It is not enough that the evidence be relevant and in this case satisfy the exception to the credibility rule in s 103 of the Evidence Act. This relatively high standard of satisfaction is consistent with the fact that the legislation to a significant extent abrogates a basic common law right.
32 In Cureton v Blackshaw Services Pty Ltd [2002] NSWCA 187, Sheller JA (with whom Meagher JA and Beazley JA agreed) said (at [37]):
I find it unusual and troubling that the cross-examination of Mr Hicks should have been stopped. S128 enabled the Judge to require the witness to give evidence if he was satisfied that the interests of justice required that the witness do so even if the evidence might tend to incriminate the witness under Australian law. He was further empowered to cause the witness to be given a certificate in respect of the evidence. The interests of justice in this context should be construed broadly and would permit questions to be put going to credit, particularly where credit was important and where the credit of the chief witness on the other side was to be impugned for conduct similar to that to be tested in cross-examination.
33 The factors which are relevant to the application of the criterion in s 128(4)(b) as identified in the cases are conveniently listed in Odgers S, Uniform Evidence Law (16th ed, Lawbook Co, 2021) (at pp 1178-1179) and counsel for Person 14 referred me to that list.
34 The focus of the submissions of the applicant and Person 14 was, respectively, the importance of the evidence in the proceeding and effects on the witness not ameliorated by the provision of a certificate should the witness be required to give evidence. That this second matter is a relevant consideration was confirmed in Gedeon (at [292] per Bathurst CJ). In R v Lodhi [2006] NSWSC 638; (2006) 199 FLR 328, Whealy J said the following (at [55]):
But the certificate does not give absolute protection. There are, for example, the indefinable but no doubt real prejudices that may result where a witness has given evidence of the kind dealt with in s 128 which may as a consequence bring him into disfavour with some sections of the community or people who have previously held the witness in high regard. Secondly, the protection may not extend to the consequences that may be involved in disciplinary proceedings instituted against professional persons or even, at a wider level, against members of the general community. In the present case, particularly, there is the subtle but real damage that can be done to the rights of Ul-Haque if the entirety of the Crown case against him, in effect, becomes the material evidence he is required to give against the accused. The position is made the worse, I consider, in the particular circumstances where he is seeking to overturn those very records of interview and have them excluded from his trial. It is not inconceivable that a successful cross-examination by Mr Boulten SC in the present matter may disrupt and indeed, shatter the professional bond of confidence existing between Ul-Haque and his counsel of choice. The very substance of the questioning envisaged by Mr Boulten SC might well lead to a question whether the matters to be put to Ul-Haque fall into the category of material that is "oppressive and unjust" in the sense mentioned by Toohey J in Hamilton's case.
35 In this case, counsel for Person 14 submitted that there may be adverse consequences to the witness if he is required to give the evidence in terms of his security classification. He referred to two paragraphs in the Media and Communication Policy, clauses 5.13 and 5.20. He also referred to the reputational consequences for the witness.
36 In relation to the first question, I was not satisfied that the interests of justice required that Person 14 give the evidence. On the one hand, s 128(4)(b) sets a high standard and it is not merely a matter of balancing the interests of justice; the Court must be satisfied that the interests of justice require that the witness give the evidence. In addition, there are, or may well be, reputational consequences should the witness be required to give the evidence and I am prepared to accept the submissions of his counsel that his security clearance may be affected even with the protection of a certificate. On the other hand, the emphasis in the applicant's submissions on the first question was on the second aspect or stage of evidence which may or may not be given and which may or may not give rise to possible inconsistencies in the witness' account of the events which were the subject of his evidence-in-chief.
37 The second question raised similar issues to the first. As I have said, I overruled the respondents' objection to the second question on the same grounds which formed the basis of my decision in relation to the respondents' objection to the first question.
38 The position in relation to the privilege against self-incrimination was different. In relation to the second question, I was given by the applicant in closed court one important piece of information which had not been provided at the time of my ruling in relation to the first question. That information was contained in a sensitive document. The document may have a substantial affect on Person 14's credibility. I say "may" because it is not my task at this stage to determine Person 14's credibility. I am determining on this application one question and one question only and that is whether the interests of justice having regard to all the circumstances required the taking of the evidence. The additional information put forward by the applicant went to the first aspect or stage of the evidence as I have described that in [30] above and that is the important difference. That first aspect or stage was, as I have said, not emphasised in the applicant's submissions with respect to the first question and what was emphasised was possible inconsistencies in terms of any account given by Person 14 to journalists. In view of these circumstances, I was satisfied that the interests of justice required the taking of the evidence and I ruled accordingly.
I certify that the preceding thirty-eight (38) numbered paragraphs are a true copy of the Reasons for Judgment of the Honourable Justice Besanko.
