41. In the present case, the Commission was given, expressly, the power to direct that the hearing take place privately. In aid of that power, the Commission was also given, in our opinion, by necessary implication, the power to take all reasonable steps, which when viewed objectively, were necessary in order to ensure that the hearing was conducted privately. The Commission is entitled to regulate its proceedings to avoid a situation arising where the confidentiality of information obtained by it may be exposed to the risk of premature disclosure (cf. National Crime Authority v. A, B and D (1988) 78 ALR 707 at p 716). This is not to say that the information should always be regarded as confidential. But, in order to conduct a hearing properly, it is necessary that the Commission have the power to prohibit, at least during the hearing itself, the disclosure of information obtained at the hearing. Publication of that material before the conclusion of the hearing could prejudice the effective conduct of the hearing. It follows, in our opinion, that it is proper to imply in the Act a power in the Commission to prevent or restrict the premature publication of evidence given at the hearing; or to put the matter positively rather than negatively, the Commission had the power, by necessary implication, to take all reasonable steps which were necessary to secure a "private", rather than a "public", hearing. The question then arises whether, in the present circumstances, the "non-disclosure" order was a reasonable step, viewed objectively, taken with a view to secure the privacy or secrecy of the hearing.
