Greiner and Environment Minister Tim Moore decided to offer Liberal-turned-independent MP Terry Metherell an executive position in the Environmental Protection Authority. If Metherell accepted the position, he would have to resign his parliamentary seat, which the Liberal Party was confident of winning in a by-election. While Metherell initially agreed to the position on 10 April 1992, it was criticised by Labor and the independents, and documents were ultimately released showing he had applied for a job in the Premier's Department and then been seconded to the EPA, and had applied after the closing date, but was appointed within hours of his application. Greiner was accused of misleading the parliament, and in late April, Labor and the independents passed a no-confidence motion in Greiner's leadership (though, critically, not against the government) in the Legislative Assembly. The pressure led to Greiner moving that the Assembly refer the matter to ICAC. The inquiry began on 5 May, and following detailed evidence by Metherell that his resignation was part of a package negotiated with Greiner and Moore and the release of Metherell's diaries, Greiner and backbencher Brad Hazzard admitted their statements to the inquiry were wrong. Greiner as a witness could not recall 20 key events under investigation, and the inquiry heard that the director-general appointed Metherell when it was discovered he could not legally be appointed to the EPA.
