A v Boulton

In the case of A v Boulton, the appellant challenged the legality of the Crime (Confiscation of Proceeds) Act 2004 (NSW) in relation to its abrogating effect on the privilege against self-incrimination. The dispute was heard by the court, which had to determine whether the Act indeed abrogated this privilege and, if so, whether such abrogation was beyond the legislative power or permissible within the context of the statutory framework. The appellant's counsel presented several arguments, including the proposition that the Act did not abrogate the privilege, and if it did, it would be beyond the power of the legislature, and that the second respondent should not be permitted to examine the appellant regarding a crime for which he was under investigation.

The court addressed each of the appellant's submissions in turn, starting with the argument that the Act did not abrogate the privilege against self-incrimination. The appellant's counsel contended that section 30(4) of the Act limited the use of answers given by a witness who claimed that the answers "might tend to incriminate" them, but this did not imply an abrogation of the privilege. The court disagreed, noting that section 30(5) provided "direct use immunity" which, when read in conjunction with section 30(4), indicated an intention to abrogate the privilege. The court referenced the decision in Pyneboard Pty Ltd v Trade Practices Commission, which stated that an intention to abrogate the privilege might be more readily implied in matters where an obligation is imposed to assist an administrative agency. The decision in Mansfield v Australian Crime Commission further supported the court's view that the Act had abrogated the privilege.

The court's reasoning was grounded in the principle that legislation will not be construed to deprive a person of an important common law right, privilege, or immunity unless a legislative intent to do so clearly emerges. The court found that the language, character, and purpose of the Act indicated a necessary implication of abrogation of the privilege against self-incrimination. The court also noted that the Act provided compensatory protection to the witness, aligning with the principle that when a legislature abrogates this privilege, it often gives compensatory protection.

The final orders of the court were that the appeal be dismissed, and the appellant was to pay the costs of the first and second respondents, with no order made for the costs of the third respondent.
