At the start of this month, the judges of Victoria’s Supreme Court all stopped wearing wigs. A similar (but broader) decision was made by the High Court in 1988:
As of today, Tuesday, 2 August, the Chief Justice and Justices of the High Court of Australia will wear black gowns when sitting in court instead of the traditional attire of a robe, jabot and wig.
While the Victorian decision was a statutory determination by the state’s Chief Justice, the High Court’s decision was not made under any statute and involved no new rules or practice directions; the Court’s seven judges simply all entered the courtroom wigless, as Murphy J and (for a time) Starke J had individually decided in the past. The Court’s press release was careful to disclaim any implications for other Australian courts:
This decision is not intended to establish a model for other courts. The fact that the High Court is a constitutional and appellate court and not a trial court has been significant in the decision to alter the dress. Different considerations may well apply to other courts. The nature of their work, particularly that of trial courts, differs from that of the High Court.
By contrast, in the case of barristers’ wigs, decisions by other Australian courts, including this week’s direction from Victoria’s common law division that barristers appearing there must do so without wigs, can directly affect what barristers wear in the High Court.
