The law of confidence is based on the moral principles of loyalty and fair dealing. An injunction was sought to restrain an intended publication: ‘The court will not restrain the publication of an article, even though it is defamatory, when the defendant says he intends to justify it or to make fair comment on a matter of public interest. That has been established for many years ever since Bonnard v. Perryman. The reason sometimes given is that the defences of justification and fair comment are for the jury, which is the constitutional tribunal, and not for a judge. But a better reason is the importance in the public interest that the truth should out. There is no wrong done if it is true, or if [the alleged libel] is fair comment on a matter of public interest. The court will not prejudice the issue by granting an injunction in advance of publication.’ and iniquity] is merely an instance of just cause or excuse for breaking confidence.’
