Loss of election (Unsworth): Beginning of Greiner's period in office; see Jim Hagan and Craig Clothier, '1988' in Michael Hogan and David Clune (editors), The People's Choice: Electoral Politics in 20th Century New South Wales, vol. 3 (1968-1999), pp. 251-281 at p. 254, (Sydney: Parliament of New South Wales and University of Sydney, 2001, ISBN 0909907412).
Change in parliamentary support: 'Following the [May] 1991 election, the government held 49 of the 99 seats against the opposition's 46 and there were four independents. Greiner unsuccessfully approached long-serving Independent John Hatton (South Coast) about the possibility of his becoming Speaker to break the deadlock. However, the coalition government secured the support of "conservative Independent" Tony Windsor and made commitments to provide significant benefits to his Tamworth electorate'; further negotiations with other independents led to the government's adoption of a 'Charter of Reform' to secure support for the Greiner coalition minority government; see Tony Smith, '1995', in Michael Hogan and David Clune (editors), The People's Choice: Electoral Politics in 20th Century New South Wales, vol. 3 (1968-1999), pp. 323-368 at pp. 323-324, (Sydney: Parliament of New South Wales and University of Sydney, 2001, ISBN 0909907412).
Change of party leader (Greiner): When Terry Metherell failed to be reappointed to the ministry after the 1991 election, he resigned from the Liberal Party and sat in the Assembly as an Independent, further weakening the position of the Greiner Liberal Party and National Party coalition minority government. In April 1992, Metherell resigned his seat in the Legislative Assembly providing the Liberal Party with the opportunity to regain control of the seat at a by-election. '[Metherell's] appointment to a senior public service role led to an inquiry by the Independent Commission Against Corruption; its report released on 19 June 1992 was critical of [Premier] Greiner's and [Environment minister Tim] Moore's parts in the affair. Proposals for a motion of confidence led to their resignations on 24 June; [Michael] Yabsley, who supported them, also resigned. Fahey was elected leader and [Bruce] Baird deputy leader. The ICAC findings against Greiner and Moore were subsequently overturned in the NSW Court of Appeal', Hughes, p. 54, (see 'Sources', below); for more details of these events, see Melleuish, pp. 457-460 (see 'References', below), and Tony Smith, '1995', in Michael Hogan and David Clune (editors), The People's Choice: Electoral Politics in 20th Century New South Wales, vol. 3 (1968-1999), pp. 323-368 at pp. 323-328, (Sydney: Parliament of New South Wales and University of Sydney, 2001, ISBN 0909907412).
