Michael Kirby J, in Osland [2008] HCA 37 (7 August), warns State sector lawyers, and private advisers to the State, of limits on the scope of legal professional privilege for state communication, saying at [89]
"It would be a mistake to assume that all communications with government lawyers, no matter what their origins, purpose and subject matter, fall within the ambit of the State’s legal professional privilege. Advice taken from lawyers on issues of law reform and public policy does not necessarily attract the privilege. Especially in the context of the [OIA], and legal advice to government, courts need to be on their guard [as they evidently had not been in the instant case, concentrating instead on issues of waiver of privilege] against any inclination of lawyers to expand the ambit of legal professional privilege beyond what is necessary and justifiable to fulfil its legal purposes."
“Free and frank advice” only covers communications with (or between) ministers. Non-privileged legal advice provided to a government CEO, for example, could not be properly withheld under the free and frank ground.
