Senators will be aware that the Government published on 2 July 2003 the Commissions of Investigation Bill, which it is hoped can provide for an alternative, more timely and cost-effective mechanism for investigations into matters giving rise to significant public concern. This would not be a single or permanent body but it is planned that commissions may be established as required and that more than one might sit at any one time. Commissions of investigation will not replace or alter in any way the work of the tribunals of inquiry currently under way or any other inquiry or investigation mechanism already available. It is envisaged that they will, instead, provide a new and alternative mechanism. In certain instances, this will be a precursor to a tribunal of inquiry. Commissions will be required to establish the factual position. A commission may be followed by a tribunal where it is unable to establish clear facts. In those situations, the evidence collected by a commission will be available to the tribunal, thereby reducing the time and cost associated with tribunals. In reducing the time and cost involved, while ensuring fair procedures and respect for confidentiality, the proposed commissions of investigation will add significantly to the mechanisms and instruments available for public investigations.
