John Robert Rau SC (born 20 March 1959) is an Australian barrister and politician. He was the 12th Deputy Premier of South Australia from 2011 to 2018 and 48th Attorney-General of South Australia from 2010 to 2018 for the South Australian Branch of the Australian Labor Party in the Weatherill cabinet. Rau was the Labor member of the House of Assembly seat of Enfield from the 2002 election until announcing his intention to retire from Parliament on 10 December 2018, and submitting his resignation on 17 December 2018. Legal career Rau was admitted as a solicitor and barrister of the Supreme Court of South Australia in 1981. He worked as an adviser to Hawke government ministers Mick Young, Michael Tate and Neal Blewett from 1985 to 1988. He served as a Commonwealth nominee on the South Australian Legal Services Commission. He has also served on the ALP State and National Executives. Before his service as a political adviser, Rau worked as a solicitor at Duncan Groom, Carabellas & Hannon. From 1988 to 1997 he worked as a solicitor and barrister at the firm of Johnston Withers, becoming a partner. Rau joined the independent bar and Murray Chambers in 1997. Rau has appeared as counsel in the South Australian Industrial Relations Commission, the South Australian Industrial Relations Court, the Workers Compensation Tribunal, the Supreme Court of South Australia (including once as Attorney-General), the District Court of South Australia and the Federal Court of Australia. Political career His first political experience as a Labor candidate occurred at the 1993 federal election, when he stood for the Division of Hindmarsh, where he was narrowly defeated by Liberal Party candidate Chris Gallus by 1.6 percent. Prior to the 2002 state election, Rau contested Labor preselection for the safe seat of Enfield. The seat had previously been Ross Smith, held by Ralph Clarke, who had recently been deposed as the party's deputy leader. The local party branch chose Clarke who received 60 of 74 votes. However, the party's state executive stepped in and installed Rau as the pre-selected candidate. Clarke ran as an independent Labor candidate, receiving a respectable 23 percent of the vote; however, Clarke narrowly fell short of overtaking Rau and winning the seat on Liberal preferences. Rau easily won the seat with a 35.9 percent primary and 65.9 percent two-party vote. He is aligned with Labor's right faction. Rau gained publicity in
