Pearce was preselected for the new seat of
Gosnells ahead of the
1977 state election, beating Nick Clarke, a telecommunications technician, and narrowly won the seat, beating his Liberal rival by 238 votes. He was appointed Deputy Opposition Whip in 1977, and in June 1978, was commissioned to write a report into improving Labor's prospects at the
1980 election. He recommended that the party concentrate its energies on "middle class" seats. From 1980, he served as the Shadow Minister for Education and Women's Interests. With Labor's election victory at the
February 1983 election under leader
Brian Burke, at which Pearce contested and won the new seat of
Armadale, Pearce was promoted to the Ministry, serving as Minister for Education in the Burke ministry. On 20 December 1984 he was also given the Planning portfolio, and on 16 March 1987 the Intergovernmental Relations portfolio. From 12 May 1986 until 25 July 1986, he was also the Minister for Police and Emergency Services after
Arthur Tonkin's departure from the Ministry. At this time he also became Leader of the House in the Legislative Assembly, responsible for managing government business, and held that position until his departure from the Ministry. When
Peter Dowding became premier in February 1988, in a cabinet reshuffle designed to move ministers from portfolios in which they had been controversial, Pearce moved to the Transport portfolio and took on the Parliamentary and Electoral Reform portfolio, overseeing the implementation of the
Acts Amendment (Electoral Reform) Act 1987 which had been steered through by former deputy premier
Mal Bryce. On 20 October 1992, it was announced by the Premier, following the delivery of Part One of the Royal Commission into
WA Inc, that a finding of improper conduct had been made against Pearce and that he would stand down from the Ministry and vacate his parliamentary seat after the next election. He was accused of acting improperly in making information public about the Liberal Party president's fund withdrawals from the Teachers' Credit Society, which failed in 1987. Pearce denied the allegations, but stated that Westminster conventions meant he was required to resign anyway. On 26 October 1992, he was replaced as Environment Minister by
Jim McGinty, and as Leader of the House by
Eric Ripper. In 1998, he became Executive Director of the Forest Industries Federation of Western Australia and in March 2008, he became director of the National Association of Forest Industries. ==References==
