the public's interest in knowing and in expressing its opinion, outweighs the need to protect confidentiality.

The High Court of Australia had earlier in Commonwealth v. John Fairfax and Sons Ltd.40 observed: “The question, then when the executive government seeks the protection given by equity, is: What detriment does it need to show? The equitable principle has been fashioned to protect the personal, private and proprietary interests of the citizen, not to protect the very different interests of the executive government. It acts, or is supposed to act, not according to standards of private interest, but in the public interest. This is not to say that equity will not protect information in the hands of the government, but it is to say that when equity protects government information it will look at the matter through different spectacles. 39 (1987) 10 NSWLR 86 at 191. 40 (1980) 147 CLR 39 at 51. Civil Appeal No. 10044 of 2010 & Ors. Page 74 of 108 It may be a sufficient detriment to the citizen that disclosure of information relating to his affairs will expose his actions to public discussion and criticism. But it can scarcely be a relevant detriment to the government that publication of material concerning its actions will merely expose it to public discussion and criticism. It is unacceptable in our democratic society that there should be a restraint on the publication of information relating to government when the only vice of that information is that it enables the public to discuss, review and criticize government action. Accordingly, the court will determine the government's claim to confidentiality by reference to the public interest. Unless disclosure is likely to injure the public interest, it will not be protected. The court will not prevent the publication of information which merely throws light on the past workings of government, even if it be not public property, so long as it does not prejudice the community in other respects. Then disclosure will itself serve the public interest in keeping the community informed and in promoting discussion of public affairs. If, however, it appears that disclosure will be inimical to the public interest because national security, relations with foreign countries or the ordinary business of government will be prejudiced, disclosure will be restrained. There will be cases in which the conflicting considerations will be finely balanced, where it is difficult to decide whether the public's interest in knowing and in expressing its opinion, outweighs the need to protect confidentiality.
