Positivity theory posits that the courts rely on powerful legitimising symbols—such as elaborate judicial attire, honorific forms of address and imposing courtroom design—to ensure legitimacy in the eyes of the public in the absence of an electoral mandate. The argument is that such legitimising symbols evoke images of learning and pageantry and create the presumption that the process by which the decision was made was fair. Typically, positivity theory has been tested by examining whether people who have a greater awareness or knowledge of the courts express higher diffuse support for their decisions. Yet, such an approach assumes that those who know more about the courts will have greater exposure to their legitimising symbols. It does not directly test if exposure to the courts’ legitimising symbols causes people to be more acquiescent with decisions with which they disagree. In this article we use a survey-based experiment to examine if exposure to the legitimising symbols of the High Court makes people more willing to accept decisions of the Court with which they disagree. We assess whether the decision of the High Court Justices to simplify their attire, including, since 1988, ceasing to wear wigs when sitting on the Bench, has adversely affected the Court’s institutional legitimacy by removing some of the mystique associated with the decision-making process. We find that exposure to the Court’s legitimising symbols is associated with higher acquiescence with decisions which people disagree with, but the Court’s decision to simplify the Justices’ attire has not adversely affected diffuse support for its decisions. Our findings are important because the Court is reliant on maintaining legitimacy to enforce the rule of law. Our results speak directly to how the Court can best take steps to increase its institutional legitimacy in the eyes of the public.

16 Similarly, studies suggest this extends to when people are better informed of the operation of courts. Once they have procedures and practices explained to them, people become more accepting of both individual decisions and the courts as a whole.

See Stephen C O’Neill, ‘Why Are Judges Robes Black?’ (2001) 119(7) Massachusetts Legal History 119, 121–2 who describes how the norm evolved. There have been a few exceptions to the norm.

52. Obviously, the High Court did not decide recent cases on these topics. Telling participants that it did and adjusting the outcome to oppose their stated preferences merely facilitated the experiment.
53. These four questions are the same as those asked in Gibson, Lodge and Woodson (n 23) in order to ascertain willingness to accept a decision of the Court with which the participant disagreed.
54. The 10 photos shown to participants in the wig treatment group, together with the description that appeared below each photo, were: (i) The first sitting of the High Court of Australia in 1903; (ii) the Justices of the High Court of Australia in 1952; (iii) the Justices of the High Court of Australia in the late 1970s; (iv) Chief Justice Marilyn Warren, former Chief Justice of Victoria; (v) Judge’s wig and law reports; (vi) the first three Justices of the High Court, 1903; (vii) Dame Roma Mitchell, Australia’s first female QC who often appeared before the Court; (viii) High Court of Australia, Canberra—Court Room 2; (ix) the High Court of Australia building in Canberra; and (x) the High Court of Australia in Canberra in session.
55. The 10 photos shown to participants in the no-wig treatment group, together with the description that appeared below each photo, were: (i) The Justices of the High Court of Australia in 2009; (ii) the Justices of the High Court of Australia in 2016; (iii) the Justices of the High Court of Australia in 2012; (iv) Susan Kiefel, Chief Justice of Australia; (v) the black robes worn in the Court by Justices (after 1988); (vi) the Justices of the High Court of Australia in 2008; (vii) Susan Crennan, Justice of the High Court 2005–2015; (viii) High Court of Australia, Canberra—Court Room 2; (ix) the High Court of Australia building in Canberra; and (x) the High Court of Australia in Canberra in session.
56. The 10 photos shown to participants in the control group consisted of a mix of people in business attire, random office buildings in Canberra and lecture theatres.
57. Dame Roma was the first woman to be appointed a Queens Counsel in South Australia (in 1962) and the first woman to be appointed a judge of the Supreme Court of South Australia in 1965. She was also the first woman to appear as counsel before the High Court (Meader v Busch (1938) 59 CLR 684). The photo that we showed participants is of Dame Roma attired as a judge of the Supreme Court of South Australia in 1965.

The transcript of the exchange between Bell J and counsel is reported here: Van Thoang Tran v Venture Solutions Australia (Supreme Court of Victoria, Bell J, 25 May 2016) <http://static1.1.sqspcdn.com/static/f/556710/27049205/1464578618617/Wigs_Bell_Victoria.pdf?token=R9uAUxhZM8ElS8T1sK566xIEy3w%3D>. It was widely reported in the media: see, eg, James Hancock, ‘Senior Lawyer Backs Victorian Chief Justice’s Ban on Barristers Wearing Wigs to Court’, ABC News (online), 27 May 2016 <https://www.abc.net.au/news/2016-05-27/victorian-lawyer-backs-ban-on-barristers-wearing-wigs-to-court/7451510>. Similarly, wigs were abandoned in Western Australia in 2009. In other state jurisdictions, much depends on whether it is a criminal or civil case with wigs typically worn in criminal cases, but not civil case: see Schoff (n 64) 40 for a detailed account of differing practices across jurisdictions.
68. While we primarily focus on the judges’ attire, the move from Queens Counsel (QC) to Senior Counsel (SC) and back again is also worth noting. Essentially, the move away from using QC was about modernisation and the vast majority of people moved to SC. Then the option of assuming the title of QC was returned and a huge majority of barristers took that up. Victoria, for example, introduced SC in 2000 and returned the option of QC in 2014 and about 89 per cent took up the option of being QC rather than SC. For example, Victoria’s most recently anointed silks have been given the option of adopting the Queen’s Counsel (QC) title: Felicity Nelson, ‘New Victorian Silks Given Choice of QC or SC’, Lawyers Weekly (online), 27 January 2015 <https://www.lawyersweekly.com.au/wig-chamber/16084-new-victorian-silks-given-choice-of-qc-or-sc>.
