When a court exercises its section 173 power to regulate its own process in a manner that affects constitutional rights, it must ensure the extent of impairment is proportional to the purpose sought. An appellate court should only interfere with such an exercise of discretion in narrow circumstances: where the court did not act judicially, was influenced by wrong legal principles, misdirected itself on facts, or reached a decision no reasonable court would reach. In balancing freedom of expression against fair trial rights, a court may adopt a test that privileges ensuring fairness of proceedings, particularly where the court remains open to the public and press and only the extension to live broadcast is at issue. The question is not whether an appellate court would have made the same decision, but whether the lower court committed a demonstrable blunder.
