Change of partisan support for Premier: Beginning of Gallagher's second period in office as Chief Minister; At the election for the ACT Legislative Assembly on 20 October 2012, both the Australian Labor Party and the Liberal Party won eight seats in the 17 seat Assembly. The ACT Greens, who had supported the previous Australian Labor Party minority government under Chief Minister Gallagher, lost three of their four seats with Shane Rattenbury as their sole representative.

Gallagher was elected as Chief Minister in the Legislative Assembly on 6 November and a list of ministers and their responsibilities was issued on 9 November 2012.

Gallagher had resigned her seat in the Legislative Assembly to take up a vacancy created by the resignation of the Australian Labor Party senator for the ACT.
