Change of party leader: Beginning of Henderson's period in office: Martin, who had won office as Chief Minister of a majority Australian Labor Party government after the Legislative Assembly election of 2001 and increased her majority at the 2005 election, resigned as Chief Minister on 27 November 2007 after dissatisfaction with her leadership within the Labor caucus and the selection of Henderson as party leader on 26 November.
Change in parliamentary support: In June 2009, the Henderson government lost its majority in the Legislative Assembly when Marion Scrymgour resigned from the Australian Labor Party over a matter of public policy. The government remained in office as a minority government with the support of Scrymgour on matters of confidence. In August 2009, another member of the Labor caucus, Alison Anderson, resigned from the party, again threatening the continuation of the Henderson government. The minority government continued with the support of Marion Scrymgour who had rejoined the Labor Party, and the Independent member, Gerry Wood.
