45 Even if judicial notice of these matters could be taken, it is very difficult to see how any conclusion drawn from these matters could be relevant to an assessment concerning costs orders. The interest of the public is not what is meant by the legal phrase 'public interest'. Indeed, as I explain in the conclusion to these reasons, the legal phrase 'public interest' is pregnant with ambiguity, uncertainty, and indeterminacy. Even if the extent of public concern was relevant to determining 'public interest', in the absence of expert evidence how could the depth and extent to which vocal public responses are truly representative be measured by a court? How could a court assess whether public concern about a programme means that litigation concerning the programme is in the interests of the public? Would such an assessment require examination of the validity or justification of the public concern? Does this require the court to engage in an exercise of weighing any arguments concerning the merits of the policy with arguments of demerit? These type of questions are classically issues of policy. They are questions which the legislature, advised by experts, and accountable to the public, is far better suited to answer. This is so even if, in some quarters, a distinction between legal principle (the domain of the judiciary) and public policy is not considered fashionable.
