Commonwealth of Australia v Frost, S

The Commonwealth of Australia brought proceedings against Frost in the Federal Court, seeking to compel the production of documents related to an investigation under the Air Navigation Regulations. Frost argued that certain documents were protected by legal professional privilege. The court had to determine whether the privilege extended to communications between Frost and his legal representatives in the context of the inquiry.

The primary issue was whether a person appearing before a Board of Inquiry, established under the Air Navigation Regulations, and entitled to be represented by a solicitor or counsel, had a right to legal professional privilege. The court needed to consider whether the statutory scheme impliedly excluded the operation of the common law privilege or whether the privilege applied as a matter of right. Additionally, the court examined whether the privilege extended to communications between the witness and their solicitor for the purpose of the inquiry.

The court found that the statutory scheme did not imply an exclusion of the common law privilege. It held that a person entitled to be represented by a solicitor or counsel in proceedings before a Board of Inquiry has a right to legal professional privilege. The privilege extends to communications between the witness and their solicitor for the purpose of the inquiry. The court held that the Chairman of the Board had erred in law in concluding otherwise.

The court declared that the Chairman of the Board erred in law in deciding that legal professional privilege was not available to Frost as a matter of right. The matter was ordered to be referred back to the Board of Inquiry for further consideration in light of the court's declaration and reasons.
