Catherine Ena "Cate" HolmesACSC (born 12 October 1956) is a retired Australian jurist who served as Chief Justice of the Supreme Court of Queensland, the highest ranking court in the Australian state of Queensland. She was appointed to the Supreme Court of Queensland in 2000, to the Queensland Court of Appeal in 2006 and appointed chief justice on 11 September 2015.[1][2] She retired on 19 March 2022.
On 16 March 2000 Holmes was appointed as a judge on the Supreme Court of Queensland. From 2004 to 2006 she was a judge on the Queensland Mental Health Court. On 26 May 2006 she was appointed to the Queensland Court of Appeals of the Supreme Court of Queensland.
On 18 January 2011, it was announced that Justice Holmes would be appointed to head an inquiry into the 2011 Queensland floods.[5] The following day the Bar Association of Queensland criticised the appointment, suggesting that it would be unconventional for a sitting judge to head an inquiry. However, Paul de Jersey, then chief justice of Queensland, defended the appointment, arguing that it was appropriate because of the apparent absence of any suggestion of political or institutional corruption.[6] Since then, there have been several inquiries led by sitting judges, without giving rise to questions of convention.[7][8]
Holmes was appointed a Companion of the Order of Australia in the 2020 Australia Day Honours for "eminent service to the judiciary, notably to criminal, administrative, and mental health law, and to the community of Queensland."[10]
