The "Presidential member" referred to is defined in s 4(1) of the Act to mean "the President, a Vice President, a Senior Deputy President or a Deputy President" of the Australian Industrial Relations Commission created by the Act. Heretofore, Presidential members of the Australian Industrial Relations Commission have enjoyed the same rank and status as Judges of the Industrial Relations Court [141] . This helps to explain the exclusion from the supervisory jurisdiction of the Federal Court of persons holding office under the Act [142] . Exceptionally, the Industrial Relations Reform Act 1993 Cth had inserted s 415 in the Act and rendered Presidential members of the Commission, along with other officers of the Commonwealth "at least one of whom is a Presidential member", amenable to the supervisory jurisdiction of the Industrial Relations Court, exercised by the Full Court of that Court. No express mention is made that the jurisdiction of the Court is to be exercised by a Full Court in relation, relevantly, to the issue of a writ of mandamus against a Judge of the Court. By inference, therefore, that supposed jurisdiction would be left to a single Judge pursuant to s 415(1) of the Act. This consequence has only to be stated to demonstrate that the Parliament did not intend to confer upon the Industrial Relations Court supervisory jurisdiction in respect of its own Judges. It is not expressly provided, as would (at least) have been necessary to alter a fundamental character of the writ of mandamus. On the contrary, the express indications given by the Parliament make it clear that no such conferral of jurisdiction was intended. The mere fact that this Court, out of its powers, may provide a direction that the matter remitted be heard by a Full Court of the Industrial Relations Court cannot alter the character of the proceeding within that Court. Despite any such direction, the proceeding would be in the original and not the appellate jurisdiction of the Court, a fact which would heighten the anomaly of remitting it to the very court to be supervised. For such a power clear and express legislative provision would be required. It does not exist here.
