First Gallagher Ministry
The First Gallagher Ministry was the 11th ministry of the Government of the Australian Capital Territory, and was led by Labor Chief Minister Katy Gallagher and her deputy Andrew Barr. It was initially appointed as a transitional ministry on 16 May 2011 following the resignation of Jon Stanhope as Chief Minister and the subsequent election of Katy Gallagher as his replacement by the Australian Capital Territory Legislative Assembly. Gallagher had stated that, once the 2011-12 ACT Budget was passed by the assembly, she would appoint her deputy Andrew Barr to the Treasury portfolio in her place. This was implemented on 1 July 2011.
The new ministry was the first step in aligning ministerial appointments with the new structure of the ACT public service as recommended by the Hawke Review and adopted by the government. To this end, a number of ministerial appointments from the final Stanhope ministry had been consolidated or removed in the new appointments.
The final Stanhope ministry contained five ministers including Stanhope. With Stanhope resigning his ministerial posts, the cabinet was reduced to four ministers. This was increased back to five ministers following the appointment of Chris Bourke to the ministry on 23 November 2011.
The ministry was replaced by the Second Gallagher Ministry after the Labor government's re-election at the 2012 election.
