Despite several seat changes reducing the Government majority to 47, equal to Labor's, thereby threatening a constitutional crisis, no problems occurred until the "Metherell affair" emerged. The former Minister for Education, Terry Metherell, had resigned from the Liberal Party in October 1991, sitting as an independent. The government subsequently created a job for Metherell, a position with the Environment Protection Agency, which he accepted, effectively engineering a vacancy in a seat that the Liberal Party would recover at a by-election. At the May 1992 by-election the seat was won by Liberal candidate Andrew Humpherson. While the Liberal Party won the by-election, there was a much higher cost. Because the Greiner government was in a minority, it could not prevent the Legislative Assembly referring the matter of Metherell's appointment to the Independent Commission Against Corruption, which made findings of corruption. Five days after the findings, on 24 June 1992, Greiner tearfully met with Sinclair at Government House and tendered his resignation. That same day Sinclair commissioned John Fahey as Premier. The ICAC findings were eventually ruled by the Supreme Court of New South Wales as being outside the powers of the ICAC to make, but by then Premier Greiner had already resigned. Metherell never took up the offered job.
