A founding member of the Labor Right faction, Atkinson was first elected to Parliament at the 1989 election. Following the 1993 election, he was shadow minister in a range of portfolios until Labor won government at the 2002 election. He subsequently became Attorney-General, Minister for Justice, Minister for Consumer Affairs and Minister for Multicultural Affairs in the Ranncabinet. In a minor cabinet reshuffle in 2004, Atkinson lost his portfolio of Consumer Affairs. He became Minister for Correctional Services in 2006. He was re-elected at the 2006 election landslide in his seat of Croydon with a 76 percent two-party vote from a 6.9 percent two-party swing toward him. At the 2010 election Atkinson was again re-elected, but with a 12 percent two-party swing against him, significantly higher than the statewide 8.4 percent two-party swing. Following his re-election, he announced he would resign from the Rann ministry but remain on the backbench. Atkinson was re-elected at the 2014 election where he picked up a 3.5 percent two-party swing toward him. On 5 February 2013 Atkinson replaced Lyn Breuer as Speaker of the South Australian House of Assembly. In September 2016, Peter Malinauskas moved house and into Atkinson's electorate of Croydon. He said of Atkinson: "Mick knows the movements of every single one of his constituents – I suspect I’m no exception.” Atkinson announced in February 2017 that he would be retiring from parliament as of the 2018 election.
Political views
Media classification and censorship
Atkinson had blocked several attempts to introduce a R18+ for video games in Australia. In a letter on the subject, Atkinson stated, "I don't support the introduction of an R18+ rating for electronic games, chiefly because it will greatly increase the risk of children and vulnerable adults being exposed to damaging images and messages." He also withdrew his support for a discussion paper released for public consultation on the subject of an R18+ rating. Unanimity from Atkinson and his fellow state and federal Attorneys-General is required for the introduction of the rating. Australia's rating system lacked a classification for games above MA15+ at the time. It therefore lacked not only an equivalent rating to the ESRB's AO rating but also an equivalent to its Mature rating. After Atkinson stepped down as Attorney-General in 2010, an R18+ rating for video games in Australia was eventually implemented in 2013. In 2009, Atkinson, in his role as attorney-general of South Australia, introduced laws into parliament that made internet commentary on the upcoming 2010 election illegal unless the commenter provided their real name and postcode. The laws were passed, and came into effect on 6 January 2010. Following public criticism, Atkinson later promised to repeal the section following the 2010 South Australian election and indicated it would not be enforced during the electoral period.
Victims' rights
In 2008, Atkinson introduced legislation aimed at increasing the rights of victims of crime. The legislation purported to allow victims to suggest a suitable sentence for the offender and made it compulsory for judges to consider imposing a restraining order on convicted sex offenders.
Casting votes
Since accepting his role as speaker, Atkinson has used his casting vote in Parliament to oppose several bills presented during the Weatherill government. These include a bill which would have allowed transgender people to have their gender officially changed on their birth certificates and another bill intended to enable voluntary euthanasia.
Personal life
Atkinson is separated from his wife, Joan, with whom he has three sons and a daughter. Atkinson's long-term and current de facto partner is fellow state Labor MP Jennifer Rankine. Atkinson is a member of the Traditional Anglican Communion, and was formerly its chancellor.
