Change of partisan support for premier: Beginning of Weatherill's second period in office; After the March 2014 general election for the House of Assembly, the Weatherill Australian Labor Party government lost its majority, winning only 23 of the 47 Assembly seats in the chamber. The Liberal Party won 22 seats, and two seats were won by Independents. After negotiations with the leaders of the Labor and Liberal parties, Independent member Geoff Brock agreed to support the Labor Party and become a minister in a Labor Party and Independent coalition government with a majority of 1 on the floor of the Assembly (note the difference between a coalition government and a minority government .
This change in the party composition of the parliamentary support for the premier meant that a second period in office had commenced for Weatherill (see previous period in office).
Further change of partisan support for premier: On 27 May 2014, Martin Hamilton-Smith, a member elected to the House of Assembly as a Liberal Party candidate and a former leader of the Liberal Party in South Australia, agreed to become a minister in the Weatherill ministry as an Independent. This gave the Weatherill Labor Party and Independent (Brock) coalition government an additional Independent member and ensured a comfortable working majority for the government. For details and commentary on this move, see Verity Edwards, 'Martin Hamilton-Smith’s ‘act of treachery and betrayal’ ensures survival of last Labor holdout', The Australian, 28 May 2014, online for subscribers: here [accessed 29 March 2018].
Shortly after the Assembly general election in March 2014, Independent member Bob Such had taken medical leave from parliament and died in October 2014. At the by-election for his seat of Fisher held in December 2014, an Australian Labor Party candidate was elected. This gave Premier Weatherill a Labor Party majority in the Assembly but he chose to continue his coalition government with the two Independents.
