Before the primary judge
62 The primary judge reasoned to the opposite conclusion to that reached by the Deputy President on the application of penalty privilege to AAT proceedings.
63 Consistently with the Deputy President, her Honour found that the cancellation of Mr Frugtniet's registration was in the nature of exposure to a penalty, by analogy with exposure to loss of office, exposure to dismissal or exposure to a disqualification order, citing Rich at [37]. As already noted, that conclusion will be assumed to be correct.
64 However, in contrast to the conclusion reached by the Deputy President, the primary judge held that the law, following Morris, Pyneboard and Sorby, was that penalty privilege was capable of applying in non-judicial proceedings, such as those in the AAT. Her Honour reasoned that the statement in Daniels at [31], reproduced above at [38], which was to the effect that there was little, if any, reason why penalty privilege should be recognised outside judicial proceedings and that no decision of the High Court had said it should be so recognised, was obiter dictum, and that it would not be correct to view those sentences as overturning Morris in finding that penalty privilege was capable of applying to non-judicial proceedings. Similarly, Rich at [24] was read down by her Honour to indicate no more than that the High Court was not prepared to give penalty privilege the same attributes as legal professional privilege.
65 The correctness of the primary judge's conclusions depends upon the observations in Daniels at [31] and Rich at [24] falling short of being "seriously considered dicta", such that they may be disregarded, especially in confronting the important distinction between penalty privilege and the privilege against self-incrimination. If those conclusions as to the nature of the observations in Daniels and Rich are not correct, the reasoning of the primary judge cannot readily be upheld by reference to other intermediate appeal court decisions.
66 The primary judge observed that the High Court has since considered penalty privilege and related privileges in judicial proceedings, but has not addressed its application in non-judicial proceedings, citing Construction, Forestry, Mining and Energy Union v Boral Resources (Vic) Pty Ltd [2015] HCA 21; 256 CLR 375, and cases considered in Boral, none of which touched on this question and none of which detracted from the conclusion that the law with respect to penalty privilege was as set out in Morris, which was said to be that penalty privilege is capable of applying to non-curial proceedings.
67 The primary judge considered a series of decisions of this Court, which her Honour accepted mostly concerned the application of penalty privilege in judicial proceedings. One exception was Griffin v Pantzer [2004] FCAFC 113; 137 FCR 209, which concerned the existence of privilege against self-incrimination in a bankruptcy examination under s 81 of the Bankruptcy Act 1966 (Cth). Particular reliance was placed by her Honour on the following paragraphs from the judgment of Allsop J (as his Honour then was, with whom Ryan and Heerey JJ agreed) at [43]-[46] (underlining added by her Honour):
43 The privilege not to answer questions or produce documents which have a tendency to expose the person to a criminal charge, or a penalty or to forfeiture has been recognised by the High Court as a deeply rooted principle of the general law: R v Associated Northern Collieries at 748; Sorby at 294, 309, 311; Pyneboard at 340, 341, 347; and Reid v Howard at 11-12, which can now be expressed also in terms of a human right: Environment Protection Authority v Caltex Refining Co Pty Ltd at 498.
44 The consequence of the recognition by the High Court that the privilege is one deeply rooted in the law as a fundamental right is that it is not merely a rule of evidence available in judicial proceedings, it is available generally, even in a non-curial context, as the foundation of an entitlement not to answer a question or produce a document: Pyneboard at 340-341; Sorby at 309; and Police Service Board v Morris (1985) 156 CLR 397.
45 Prior to Pyneboard, it had been generally expressed that the privilege was inherently incapable of application in non-judicial proceedings. In this form, it was seen as a testimonial privilege. That was the view of Wigmore, Wigmore on Evidence at [2263], of the United States Supreme Court: see, for example, Re Harris 221 US 274 (1911), and of the Full Courts of New South Wales and Victoria: see the cases cited in Pyneboard at 337-338; and see generally Phipson on Evidence pp 198-203. There was, however, a contrary line of authority: see the discussion in Pyneboard at 337-340.
46 It is presumed that Parliament does not intend to interfere with fundamental principles or rights including entrenched general law rights, such as the privilege against self-incrimination, without expressing its intention clearly, whether by express words or necessary implication: Potter v Minahan (1908) 7 CLR 277 at 304; Sorby at 294-295, 309-310; Baker v Campbell (1983) 153 CLR 52 at 96-97, 116, 123, 132; Re Bolton; Ex parte Beane (1987) 162 CLR 514; Annetts v McCann (1990) 170 CLR 596 at 598; Bropho v Western Australia (1990) 171 CLR 1; Coco v The Queen (1994) 179 CLR 427 at 437; Commissioner of Australian Federal Police v Propend Finance Pty Ltd (1997) 188 CLR 501; Daniels at [11], [43], [88]-[94] and [132]-[134]; and Plaintiff S157/2002 v Commonwealth (2003) 211 CLR 476 at [30].
68 The above paragraphs from Griffin v Pantzer were said by the primary judge to identify penalty privilege as a principle of the general law, not confined to a court setting, with a presumption raised by the principle of legality against its statutory abrogation in the absence of express words or necessary implication. With great respect to her Honour, it is difficult to see how that interpretation of the passages reproduced above was able to be reached with such certainty. The first passage underlined above does refer to penalty privilege, but that does not change the fact that the decision was concerned with the privilege against self-incrimination, and not penalty privilege. The possible conflation of the two privileges in that passage cannot change the ratio of the decision. Moreover, there was no reasoning aligning the two privileges, because none was required.
69 The passing reference in Griffin v Pantzer to penalty privilege was made in the course of deciding that the privilege against self-incrimination was not available as a matter of statutory construction. By parity of reasoning, no lesser privilege, such as penalty privilege, would have been available either, had that been relied upon, which it apparently was not. Moreover, if the reference to a "deeply rooted principle of the general law" is intended to suggest that penalty privilege, like the privilege against self-incrimination, is not just a substantive rule of law but an important and fundamental common law immunity, which it may be doubted that Allsop J was intending to convey, that is contrary to Daniels and Rich, which must prevail.
70 The reference to "privilege" in Griffin v Pantzer at [44] is, in context, a reference only to the privilege against self-incrimination, notwithstanding the wider passing reference in [43] to the penalty privilege. The preceding paragraphs from [27] to [42] in Griffin v Pantzer were all dealing with the privilege against self-incrimination, not penalty privilege and, even then, in the context of testimonial privilege. In any event, even if the comment was to be regarded as a reference also to penalty privilege, it must only be an obiter comment, which does not have the status of the obiter comments in Daniels and Rich to the contrary.
71 Griffin v Pantzer was regarded by the primary judge as stating the law in a manner consonant with other intermediate appeal courts, with particular reliance on the decision of the New South Wales Court of Appeal in Valantine v Technical and Further Education Commission [2007] NSWCA 208; 166 IR 459 and the Victorian Court of Appeal in Towie, as applied in MH6 v Mental Health Review Board [2009] VSCA 184; 25 VR 382. However, those cases dealt with State tribunals and legislation, contexts which do not safely translate to a federal context. It is neither necessary nor desirable to comment upon the correctness or otherwise of those decisions.
72 Based on the primary judge's treatment of the privilege against self-incrimination and penalty privilege as relevantly equivalent, in line with the implied assumption made in Morris, her Honour regarded the statutory construction exercise as requiring a basis for abrogation or curtailment of penalty privilege, not its application. Her Honour set out the principles and leading authorities dealing with the abrogation of fundamental rights before turning to the AAT Act and Migration Act. The correctness of those principles and authorities is not in doubt when the question of abrogation of such a right properly arises. Her Honour did not find anything in the relevant provisions of either Act that operated to abrogate the penalty privilege that was already found to otherwise exist and apply. The primary judge did not carry out any statutory construction exercise to derive positively the application of penalty privilege to Mr Frugtniet's AAT proceedings.
