Australian Securities and Investments Commission v Managed Investments Pty Ltd (No 6)

In the case of Australian Securities and Investments Commission v Managed Investments Pty Ltd (No 6), the primary issue before the court was whether the CEO of Managed Investments Pty Ltd, who had been charged with two offences under the Securities Act 1978 (NZ), could claim a privilege against self-incrimination to refuse to answer whether he had signed an affidavit in the current proceedings. The court had to determine if the common law privilege against self-incrimination applied when the witness had already affirmed an affidavit and whether this privilege extended to incrimination under the laws of any jurisdiction.

The legal issues centred around the extent and application of the common law privilege against self-incrimination, particularly in circumstances where a witness had already signed an affidavit but refused to answer questions about it during the examination in chief. The court needed to decide if the privilege could be invoked by a witness who had already affirmed an affidavit and whether this privilege could be used to avoid answering questions in court.

The court ruled that the common law privilege against self-incrimination did not apply in the circumstances of the case. It held that once a witness had affirmed an affidavit, they could not refuse to answer questions about it during the examination in chief on the basis of privilege. The court directed the witness to answer the question regarding whether he had signed the affidavit, concluding that the witness could not claim privilege after already having affirmed the affidavit.

The court's decision underscored the principle that the privilege against self-incrimination does not extend to situations where a witness has already affirmed an affidavit. This ruling reinforced the need for witnesses to answer questions about their affidavits without invoking privilege after having already affirmed them.
