I fully agree with his Honour. Once it is accepted, as it must be, that despite the fundamental nature of the privilege against self-incrimination, it can, nevertheless, be excluded otherwise than by the use of express language, then the phrase "to the extent that the person is capable of doing so" achieves that result. Resort to the explanatory memorandum which indicated the intention to exclude the privilege, is, in my view, unnecessary. For the reasons given by Carr J and the reasons given in Stergis and Donovan the language chosen must be viewed as inconsistent with the availability of the privilege. It does not matter whether the passage from Pyneboard is directly binding on this Court or is merely highly persuasive. The language of the statute speaks for itself.
The respondent also sought a reversal of his Honour's finding that it was not established on the facts that the notice served under s 264 was issued for an improper purpose. Hill and Lindgren JJ agree with this finding. I am also satisfied that there are no grounds on which to reverse his Honour's finding. I do not wish to add to the reasons given by Hill and Lindgren JJ in this regard.
It was also submitted before this Court, as before Carr J, that the provisions of Article 14(3)(g) of the International Covenant on Civil and Political Rights required that the phrase under consideration should be construed so as to accommodate the privilege against self-incrimination. This Covenant was ratified by Australia on 13 November 1980 but has not been incorporated into Australian municipal law. The respondent relied upon the decision of the High Court in Minister for Immigration v Teoh (1995) 128 ALR 353 for the proposition that the ratification of an international treaty is sufficient to found a legitimate expectation that a decision-maker will act in conformity with it. I agree with Carr J and Hill and Lindgren JJ, for the reasons their Honours have given, that the provisions of the Covenant are not relevant to the question with which we are concerned in this case.
I, therefore, agree that the cross-appeal should be dismissed.
I turn, then, to the appeal. The appellant challenges Carr J's decision that ss 8C and 8D of the Administration Act do not prevent a person from refusing to answer questions and provide information sought pursuant to a notice under s 264 of the Act, on the ground that a demand for compliance could amount to contempt of court. His Honour reached this decision in the context of an admission by the appellant that the intended questioning of the respondent would cover factual areas which were germane to the criminal proceedings already brought against him in the Western Australian District Court. The nature of these proceedings are set in the judgment of Hill and Lindgren JJ and I shall not further refer to them in these reasons.
Hill and Lindgren JJ agree with Carr J. I agree with their Honours' conclusions and with their reasons for reaching them. However, as this involves disagreement with the decision of Wilcox J in this regard in Donovan, I wish to make some brief observations of my own.
It is convenient to state some preliminary matters. First, the inquisitorial and investigative powers provided for by s 264 of the Act are clearly given only for the purpose of obtaining information for the collection and protection of the revenue. Indeed, it has been asserted on behalf of the appellant and accepted at first instance and in this Court, that the questioning of the respondent is intended only for these purposes. The use of these investigative powers for the collateral purpose of obtaining evidence for use in a prosecution already launched, would be an improper purpose and one which would vitiate the use of the power. It would not, in effect, be a use authorised by the Act. Of course, a finding was made by Carr J and which should be upheld by this Court that no such improper purpose exists in the present case.
The situation therefore exists that the appellant wishes to examine the respondent in circumstances where the respondent cannot claim the privilege against self-incrimination. The examination is to take place in private and in the absence of any improper purpose on the part of the examiner. It is submitted on behalf of the appellant that, in these circumstances, no question of contempt of the District Court prosecution proceedings can arise.
It must be noted, however, that neither in the proceedings before Carr J nor in the appeal before this Court, has the appellant been prepared to give an undertaking that the material it obtains in the investigation under s 264 of the Act will not be made available to the prosecution. It is conceded that by virtue of statutory provisions which, for present purposes, need not be examined, the information could be forwarded to the prosecution irrespective of the absence of any intention for the time being to do so. It was submitted, however, that any answers given by the respondent under the compulsion of s 264 could not find their way into evidence in the prosecution because they would not be "free and voluntary". It was further submitted that, in any event, these considerations could have no bearing upon the construction of the statutory language which, by necessary implication, excludes reliance upon the doctrine of contempt of court.
It is necessary to consider the major authorities to which Wilcox J had regard in Donovan and which were considered by Carr J at first instance. Before doing so, I find it convenient to observe that during the course of argument counsel for the appellant tended to equate abrogation of the privilege against self-incrimination with exclusion of the contempt of court doctrine. He asserted that if the examinee were obliged to answer questions notwithstanding that the answers might incriminate him, then no contempt of court could arise from the putting of the questions, especially in circumstances where there was no ulterior purpose in the questioning. If it was intended to put this as a universal proposition, it cannot be accepted.
The privilege against self-incrimination is a fundamental safeguard given by the common law to an individual and can only be taken from him by the manifestation in statute of a clear legislative intention to do so. It is, nevertheless, personal to him. The doctrine of contempt of court, however, focuses upon a court's right and, indeed, its obligation, to protect the integrity of its operations and to prevent interference with its administration of justice. This may, of course, involve enforcing an individual's privilege against self-incrimination but it also encompasses a court taking other steps to ensure that its processes are not contaminated by unfairness. It does not follow, even where there is a statutory abrogation of the privilege against self-incrimination, that a court is not necessarily concerned to exclude other elements of unfairness or prejudice which may operate to the disadvantage of an accused contrary to the spirit of the common law.
It is clear from Victoria v Australian Building Construction Employees' and Builders' Labourers Federation (1982) 152 CLR 25 that even in the absence of an intention to interfere with the course of justice, the establishment or continuation of an administrative inquiry will be a contempt if there is an actual interference with the administration of justice or "a real risk, as opposed to a remote possibility" of such an interference (see per Gibbs CJ at 56).
The case of Hammond v The Commonwealth of Australia & Ors (1982) 152 CLR 188 is important for present purposes. It concerned s 6 of the Royal Commissions Act 1902 (Cth) which made it an offence for a witness before a Commission to refuse to answer any question relevant to the inquiry which was put to him by any member of the Commission. Section 6DD provided that any statement or disclosure made by such a witness in answer to such a question would not be admissible in evidence against him in any civil or criminal proceedings. It may be observed, therefore, that such a witness was in a better position than the present appellant. Although he was obliged by s 6 to answer questions, he was afforded a statutory safeguard against the use of his answers in other proceedings. In this case the appellant is provided with no such safeguard.
Hammond was committed for trial in April 1982 on a charge of conspiring with others to commit an offence against a law of the Commonwealth. In June 1982 he was called before a Royal Commission and asked questions about this conspiracy. It was held that, notwithstanding his answers would not be admissible in evidence against him, his examination before the Royal Commission would interfere with the due administration of justice. It is necessary to set out two passages from judgments in the case which have since been considered. The first is a passage from the judgment of Gibbs CJ (at 198):-
"Once it is accepted that the plaintiff will be bound, on pain of punishment, to answer questions designed to establish that he is guilty of the offence with which he is charged, it seems to me inescapably to follow, in the circumstances of this case, that there is a real risk that the administration of justice will be interfered with. It is clear that the questions will be put and pressed. It is true that the examination will take place in private, and that the answers may not be used at the criminal trial. Nevertheless, the fact that the plaintiff has been examined, in detail, as to the circumstances of the alleged offence, is very likely to prejudice him in his defence. In the Builders Labourers' Case I expressed the opinion that, if during the course of a commission's inquiries into allegations that a person had been guilty of criminal conduct, a criminal prosecution was commenced against that person based on those allegations, the continuance of the inquiry would, generally speaking, amount to a contempt of court, and that the proper course would be to adjourn the inquiry until the disposal of the criminal proceedings. Of course, the present inquiry is not simply into allegations against the plaintiff. It is an inquiry into alleged malpractices in connexion with the export of beef that are said to have caused immense damage to the reputation of our meat industry. It would be neither necessary nor right to adjourn this inquiry because a prosecution had been commenced against the plaintiff. But the public interest can be met, and the interest of justice at the same time safeguarded, if the inquiry proceeds to its conclusions without further examination of the plaintiff.
I would therefore restrain the defendants from examining or resuming the examination of the plaintiff under the Commissions until the determination of the trial."
