Disclosure of Information in UK Law

In order for a statement or disclosure to be a qualifying disclosure according to this language, it has to have a sufficient factual content and specificity such as is capable of tending to show one of the matters listed in subsection (1). The statements in the solicitors' letter in Cavendish Munro did not meet that standard.

They seem to me to point to a very reasonable principle that if through no fault of his own a person gets mixed up in the tortious acts of others so as to facilitate their wrong-doing he may incur no personal liability but he comes under a duty to assist the person who has been wronged by giving him full information and disclosing the identity of the wrongdoers.

For these reasons, the test to be applied when considering whether it is necessary to restrict freedom of expression in order to prevent disclosure of information received in confidence is not simply whether the information is a matter of public interest but whether, in all the circumstances, it is in the public interest that the duty of confidence should be breached.

What does, however, emerge clearly from the opinions are four propositions. First, neither article has as such precedence over the other. Secondly, where the values under the two articles are in conflict, an intense focus on the comparative importance of the specific rights being claimed in the individual case is necessary. Thirdly, the justifications for interfering with or restricting each right must be taken into account. For convenience I will call this the ultimate balancing test.

By the uniform practice of the judges which by the time of Marks v. Beyfus had already hardened into a rule of law, the balance has fallen upon the side of non-disclosure except where upon the trial of a defendant for a criminal offence, disclosure of the identity of the informer could help to show that the defendant was innocent of the offence. In that case, and in that case only, the balance falls upon the side of disclosure.

It is that, although the basis of the law's protection of confidence is that there is a public interest that confidences should be preserved and protected by the law, nevertheless that public interest may be outweighed by some other countervailing public interest which favours disclosure.

As to what degree of likelihood makes the prospects of success 'sufficiently favourable', the general approach should be that courts will be exceedingly slow to make interim restraint orders where the applicant has not satisfied the court he will probably ('more likely than not') succeed at the trial.
