The history of s 128
19 The certificate procedure in s 128 of the Evidence Act reflects a modification of what is referred to generally as the common law privilege against self-incrimination. That privilege entitles a person to refuse to answer any question, or produce any document, if the production would tend to incriminate that person: Sorby v Commonwealth (1983) 152 CLR 281 at 288. Section 128 also encompasses the distinct privilege against self-exposure to a civil or administrative penalty, also known as penalty privilege. Both aspects - privilege against self-incrimination and penalty privilege - will be considered as a single privilege for the purposes of these reasons, although there are some important differences which do not presently need to be explored.
20 As Crennan J observed in Lee v New South Wales Crime Commission [2013] HCA 39; 251 CLR 196 at [134]:
In different contexts, legislatures have abrogated or modified the privilege against self-incrimination, and the closely related but not co-extensive right to silence, when public interest considerations have been elevated over, or balanced against, the interests of the individual so as to enable the true facts to be ascertained.
21 The House of Lords, now the Supreme Court of the United Kingdom, in addressing such a modification and balancing exercise in relation to the interrogation powers of the Serious Fraud Office, said in R v Director of Serious Fraud Office; Ex parte Smith [1993] AC 1 at 30 that the general immunity from being compelled, on pain of punishment, to answer questions the answers to which may incriminate a person, was to be regarded as one of a number of a group of disparate immunities falling under the general expression of the "right to silence". When considering a statutory modification, it is necessary to look at the reasons behind the immunity in the first place, in order to understand better what the modification is seeking to achieve.
22 Properly understood, the privilege is to be understood as a negative right to resist compulsion. It reflects "the long-standing antipathy of the common law to compulsory interrogations about criminal conduct": Lee at [1] per French CJ.
23 In considering the operation of s 128 as a modification of the privilege, it is useful to have regard to an Interim Report delivered by the Australian Law Reform Commission in 1985, ALRC 26 (ALRC Report), which preceded the enactment of the provision and addressed the issue of whether the common law privilege against self-incrimination should be abolished or instead modified. The ALRC recommended that the privilege be retained in modified form by way of the adoption of a certification procedure that was modelled, with some variations, on provisions operating in the Australian Capital Territory. The recommendation was summarised at xxxviii as follows:
At common law, a witness can object to answering any question the answer to which may tend to incriminate him. This privilege has been subject to various modifications in different jurisdictions. In particular, in Western Australia, Tasmania and the Australian Capital Territory there is a certification procedure under which a judge may grant a certificate which either confers immunity from prosecution on the witness or renders any evidence that he may give inadmissible against him in any subsequent criminal proceeding. In recent years the issue has been raised as to whether the privilege should be abolished. This issue is considered in the report. The conclusion reached is that the privilege should be retained as a protection of the individual's personal freedom. It is, however, recognised that the privilege can deprive the courts of information relevant to the proceedings and thus make the fact finding task more difficult. The Commission has formed the view that the proper solution in light of the competing interests is to retain the privilege in a modified form. A modified version of the certification procedure operating in the Australian Capital Territory is proposed. Under this proposal a witness may claim the privilege but if he is prepared to testify, the judge may issue a certificate which will prevent the evidence being admitted against him in subsequent legal proceedings. Unlike the ACT provision, the certificate will only be issued if the witness consents to the procedure. The decision will be for the witness, not for the judge.
24 The recommendation of the ALRC for a certification procedure was ultimately adopted by the enactment of s 128, save that a court was given the power to require the giving of evidence under certificate notwithstanding that a witness might not consent: see s 128(4).
25 The ALRC Report was tabled in the Parliament of the Commonwealth on 21 August 1985, long before the commencement of the Evidence Act, and s 128 in particular, in 1995. Accordingly, it may be considered in confirming the ordinary meaning of the text or determining the meaning of s 128 where any ambiguity or obscurity arises, or where the ordinary meaning of the provision leads to an absurd outcome: s 15AB(1) and (2)(b) of the Acts Interpretation Act 1901 (Cth).
26 The ALRC Report summarised the existing position as to the privilege as follows:
464. Common Law. A number of difficulties exist with the interpretations of the common law privilege:
• aspects of the privilege may be criticised as anachronistic; particularly, those that have allowed its invocation where it would expose the witness to ecclesiastical censure, notoriety of adultery, disgrace or liability to forfeiture;
• many judges perceive themselves under no obligation to inform a witness of his right to claim the privilege, meaning that witnesses who have not received legal advice may incriminate themselves without realising that they were not obliged to;
• should a judge compel the giving of testimony by a witness and in the course of that discover that the testimony was in fact self-incriminating, at common law it is probable that the witness has no alternative but to suffer the consequences; no retrospectivity of protection is available.
Some critics argue that the privilege should be abolished. This issue is considered in the Commentary to the Proposals.
465. Legislation. Aspects of the present certification provisions cause concern:
• The operation of the certification provision depends entirely upon the exercise of an unguided discretion. The decision has potentially grave consequences for the witness. The consideration ('in the interests of justice') gives no guidance. Is the judge to consider what consequential evidence might be obtained? He cannot do this without knowledge of the evidence the witness is likely to give.
• The judge is placed in the position of deciding whether the witness must be compelled to answer the incriminating questions. It is a proper matter for concern that a judge may be seen to be forcing people to give such evidence in the exercise of his unfettered discretion.
• Once the judge has made the decision, the witness on being informed of the availability of the certificate must answer the questions regardless of what the answers may reveal - he has no choice in the matter.
• The witness will receive the certificate only if he answers all the questions. If some unforeseen issue arises and he is questioned about it, he must answer.
27 The ALRC report explained the rationale for the privilege which the recommended certification procedure was intended to modify as follows:
852. Rationale. The issue to be considered is the availability to a witness of a right to object to answering questions on the ground that, to do so, may expose the witness to the risk of criminal and other proceedings adverse to him. Several justifications have been suggested:
• A Fundamental Human Right. The privilege developed in response to the abuses of past centuries, including the practices of the Star Chamber. It has persisted and is now supported by many as a human right. Justice Murphy has recently spoken of the correlation between human rights and the right to privacy on the one hand and the existence of a privilege against self-incrimination on the other:
The privilege against compulsory self-incrimination is part of the common law of human rights. It is based on the desire to protect personal freedom and human dignity. These social values justify the impediment the privilege presents to judicial or other investigation. It protects the innocent as well as the guilty from the indignity and invasion of privacy which occurs in compulsory self-incrimination; it is society's acceptance of the inviolability of the human personality.
Griswold remarked that 'the privilege against self-incrimination is one of the greatest landmarks in man's struggle to make himself civilised. It has been referred to as a 'fundamental bulwark of liberty'.
• It has, however, been suggested that it is not entirely proper to classify the privilege against self-incrimination by the emotive terminology of 'fundamental human right'. It has been argued that the privilege came into existence as a means of protection from the abuses of the process in the seventeenth century, notably the Star Chamber, and that with current procedural and evidentiary protections it is not a necessary concomitant of a fair and humane criminal justice system. Whatever its origins, however, the role it plays in defining the relationship between the individual and the State is significant and warrants the categorisation of 'human right'. It also reflects and supports the philosophy that the State must prove its case without recourse to the suspect. It also protects people against oppressive official behaviour. It must be acknowledged, however, that the protection given outside the courtroom is more necessary than that given in it. In the courtroom controls exist to protect the witnesses. It should also be noted that while one can speak of the privilege in terms of human rights, there is only arguable support in the International Covenant for treating the privilege applied in the courtroom as a human right.
• Encouraging Persons to Give Evidence. The privilege against self-incrimination may encourage witnesses to testify. Its effect is that the witness can give evidence without fear of having to give answers against his own interests. However, the State can give a witness protection by granting a nolle prosequi in respect of offences as to which it is desired that he give evidence. The decision on the entering of a nolle prosequi, though, is that of the Attorney-General alone. Its protection, however, is limited. A nolle prosequi terminates the particular proceedings but is not a discharge or an acquittal on the merits and the courts have been 'almost unanimous in holding that it is no bar to new criminal proceedings'. Thus, the procedure affords a qualified protection to the witness, his fate resting on the continuing good will of the State.
It is clear that the carrot of not having to give evidence on any subject that may incriminate a witness will have some effect upon those considering giving evidence before the courts. How much effect it will have, however, is another matter. The mere fact of refusal to testify on a certain matter puts the relevant authorities on clear notice that a witness has something to hide.
• Avoidance of Undue Hardship and Perjured Testimony. The witness can escape the unpleasant dilemma of choosing between harmful disclosure, contempt, and perjury. It may be said that a privilege is a reflection 'of a humane attitude which saves even the guilty from a harsh choice among perjury, recalcitrance or confession'. It must be remembered, however, that the problem arises because of the witness' past misdeeds. If his slate is clean, the compulsory questioning as to whatever is relevant to the matters in issue is unlikely to cause undue distress or hardship.
• Avoiding Suspect Evidence. If a witness is compelled to answer incriminating questions the quality of the evidence provided may well be suspect because of the likelihood of perjury. The privilege may, thus, be viewed as a recognition by the law of the folly of commanding the unlikely and the untrustworthy. This argument is one of the strongest for retaining the privilege in its traditional form. It is doubtful, for example, whether significant amounts of additional and relevant evidence would be obtained by the substitution for the common law of a certification procedure barring only the use of the witness' words in later proceedings.
28 The ALRC Report then considered a number of arguments for the abolition of the privilege, which were summarised at [853] as follows:
853. Arguments for Abolition of the Privilege. The foregoing considerations warrant the retention of an appropriate form of protection for witnesses. The critics, however, argue that the blanket privilege tilts the balance too much in favour of the individual against the State. It has been said that the privilege is a 'hiding place of crime':
Overwhelming difficulties confront the government today in the detection and prosecution of crime. In the case of a large number of offences the proof is difficult, if not impossible of ascertainment without the testimony of individuals accessory to the act.
Douglas Meagher QC recently has expressed grave concern to a similar effect:
It is not putting it too highly to say that if the privilege against self-incrimination is allowed to continue, there will be a whole class of highly intelligent people in our community who will be able to perpetrate massive criminal schemes with impunity. Their belief that they can do so has already arisen, as is shown by the massive taxation fraud of the last decade.
Justice Stewart recommended changes to the Commissions of Enquiry Acts 1950-1954 (Queensland) and the Evidence Act 1958 (Victoria) so that Commissions of Enquiry have power to compel persons appearing before them to answer relevant questions whether or not any such answer may or may not tend to incriminate such persons.
29 In support of its recommendation that the common law privilege should be retained, albeit in modified form, the ALRC considered that the following options were available:
(1) certification, with the evidence then given not being admissible in subsequent proceedings;
(2) certification, with neither the evidence nor consequential evidence being admissible in subsequent proceedings (these days commonly referred to as a "use/derivative use" prohibition);
(3) certification being a bar to prosecution - in effect, a statutory transactional indemnity - but with doubtful legislative capacity of the Commonwealth to bind the States; or
(4) optional certification, by which the witness would be able to choose whether or not to be given the certificate and thus give evidence, with the certificate affording protection against use of the evidence in subsequent proceedings.
30 Ultimately, the optional certification model referred to at (4) of the preceding paragraph was recommended by the ALRC. That was the only model that would have left the final question of whether evidence should be given under certificate in the hands of the witness. It will be apparent, however, that the model that was implemented by the legislature was the second model outlined above. That option provided for evidence to be compelled by a judicial officer if so ordered under s 128(4), but with protection from "use/derivative use" in subsequent proceedings by virtue of s 128(7).
31 It is instructive to consider the full terms of the ALRC's proposal, noting that the interpretative assistance to be derived from this aspect of the ALRC Report may be seen to be diminished in light of the legislature having declined to adopt the ALRC's recommendations in full. The relevant passage was as follows:
862. Proposal. The optional certification procedure is put forward as the preferred alternative. For the reasons given above, it best addresses the competing policy issues. Specific features of the proposal should be noted.
• Ambit of the Provision. A witness under the proposal is limited in his right to object to refusing to give evidence on the ground that it may tend to show that he has committed an offence or is liable to a civil penalty. A witness cannot refuse to give evidence on the ground that it might tend to 'disgrace' him, show him guilty of forfeiture or adultery or meriting of ecclesiastical censure. Anachronisms present in the existing law are, therefore, removed.
• Limits to Provision. Evidence with the protection of the certificate may still be given in respect of proceedings for perjury brought in respect of the evidence given:
• Oral/Documentary Evidence. No distinction is drawn in the legislation between the giving of oral and documentary evidence. This reflects the current position. A difference may be said to be that the document in issue in most cases will be one that has been brought into existence for purposes unrelated to the court proceedings. Oral and documentary testimony are, however, often intimately related.
• Natural Persons/Corporations. The law at present in England is that the privilege against self-incrimination applies to an answer tending to incriminate a corporation. The High Court has yet to rule on this question. Expressions of opinion on the subject have not as yet been received by the Commission although some debate in respect of the privilege arose in discussions concerning the National Crimes Commission Act 1982. It is not proposed at present to delimit the privilege or the protection accorded by the indemnity provisions by expressly excluding corporations. The issue will not arise in the courtroom because of the logistic problem that a corporation cannot testify in the box. It is not proposed to advance specific proposals. The Commission's view, however, is that the rationale for the privilege does not warrant its extension to corporations. The issue would have to be faced, however, if the proposals are to be applied to pre-trial discovery.
• Availability to Spouses. The protection in the legislation is not extended to questions incriminating spouses. It is doubtful whether the common law privilege extends to such questions. While there are dangers of unreliability of evidence tending to incriminate a spouse, it is felt that this should reflect upon the degree of weight to be attached to the testimony rather than its admissibility. Where the witness is the spouse of the accused, the non-compellability discretion will be available.
• Retrospective Certification. Where an objection to giving evidence has been overruled by the court and the witness has given evidence which would tend to show that he has committed an offence or become liable to a civil penalty, the court may give a certificate to cover the evidence so compelled. This provides flexibility and a mechanism for the court to correct what may have been an erroneous ruling. It is an additional safeguard for the witness and is analogous with the common law.
• Informing of Rights. Under the draft legislation, the court must satisfy itself that the witness is aware of his rights.
• Constitutionality. There do not appear to be any constitutional impediments to the legislation as proposed. As an exercise of powers incidental to the judicial head of power, the effect of the Commonwealth legislation will be that the certificate issued by a federal court will be recognised by all courts in Australia. This provides real protection for admissions against interest compelled by the certification procedure and introduces uniformity in the area so far as it can be achieved by federal legislation.
• Inferences from Claim of Privilege. No adverse inference should be drawn from the fact that privilege is claimed. Under existing law, no adverse inferences should be drawn where a person claims a privilege. It is not thought to be necessary, therefore, expressly to forbid the drawing of adverse inferences.
32 As can be seen from the above passages, the ALRC Report did not suggest that what was in contemplation by the enactment of a certification procedure was a wholesale change to the nature of the privilege against self-incrimination and how it would operate. Quite to the contrary. The submissions calling for abolition of the privilege were dutifully recorded, but nothing more than modification was recommended.
33 That recommendation was for the complete retention of protection against any compulsion to give evidence, with the alternative certification process being optional to the witness and conditioned on their consent. There is nothing in the ALRC Report to suggest that there was perceived to be a problem with party witnesses having to make a choice about whether or not to give evidence in chief that might tend to incriminate them by way of use in a later investigation, prosecution or civil penalty proceeding, in return for obtaining the benefit of such evidence. When in fact compelled to answer questions under cross-examination, a party witness would have the same protections under s 128 as any other witness who might seek to refuse to answer questions on the ground that it may tend to incriminate him or her.
34 It is clear from the foregoing that the ALRC's focus was on balancing the individual's right or interest in not being compelled to give evidence that may tend to incriminate or expose him or her to penalty, and the public interest in having such evidence available to a court. In this regard, the report considered, in the form of different options canvassed, how best to compensate for the loss of the right to remain silent, and whether there should be retained any choice in the hands of the witness. At the centre of the ALRC's proposal was the question of the Court's power to compel the giving of evidence. There is nothing to indicate that the ALRC was considering whether the choices available to a party witness to control the evidence that he or she elected to give in an affidavit or in oral evidence in chief should be changed in any way.
35 What was lost in the statutory bargain that was ultimately legislated for by the enactment of s 128 was, in the confined circumstances in which that provision applied, the right to remain silent. The introduction of a means of compelling the giving of evidence that would otherwise be covered by the privilege was to be compensated for by protection from the use of that evidence in subsequent proceedings. The putative witness was, at least in a formal sense, worse off, but only to the extent that his or her evidence, which would otherwise be protected by the certificate, might be both known publicly and used in some way in the proceedings in which the evidence was given. To that extent, the privilege was wound back in a protected way, trading a private right or interest for a public interest. It was not a gain for the witness but, rather, a compensated loss.
36 By contrast, to extend that statutory bargain to a party witness in the absence of compulsion would be to bestow a gain on an individual to advance his or her private interest in litigation, protected from the adverse consequences that might otherwise arise from use of that evidence. Such an outcome would be divorced from the clear historical roots of the privilege as an immunity from compulsion that is closely related to the right to silence, as opposed to a positive right to advance a forensic desire. Even if there is any public interest to be had from such an outcome, it would be incidental and secondary to the private interest. That was not any part of the reasoning of the ALRC in recommending a limited modification of the privilege as an alternative to its complete abolition.
