Evans unsuccessfully contested the
1975 Senate election as a
Liberal Movement candidate. In 1977, as an organiser for the
New Liberal Movement, he was closely associated with
John Siddons,
Robin Millhouse and others in formation of the
Centre-Line Party which was later renamed the Australian Democrats. He has been credited with recruiting
Don Chipp as leader of the new party for which he unsuccessfully contested the
1977 and the
1980 Senate elections as the lead
WA Democrat candidate. In 1980, he polled above 12% before losing the final seat to Liberal
Noel Crichton-Browne in a tight preference count. He eventually gained election at the
March 1983 double dissolution election on his third attempt as an Australian Democrats candidate. He was defeated at the
December 1984 election, his seat being won by
Jo Vallentine of the
Nuclear Disarmament Party. (Though he sat for only 28 months, his term was officially deemed to have begun on 1 July 1982 and ended on 30 June 1985.) At the
1986 Western Australian state election, he contested an Upper-House seat in circumstances which led to allegations that he had unethically negotiated Labor Party funding assistance in return for crucial
election preferences. For the
following Senate election in 1987, the party's membership selected him as the No. 2 Senate candidate, precipitating a bitter dispute and a second preselection ballot from which the first ballot winner, Richard Jeffreys, was excluded. Evans was again placed in the second position, deemed unwinnable, this time behind
Jean Jenkins, who was successful at the election. In 1988, he survived an expulsion motion from the party's WA branch and for several years withdrew from constructive participation while conducting disputes with the party's WA administration and its national ombudsman. During that time, he mounted an unsuccessful Supreme Court action to prevent circulation of a national ombudsman's report, and acted as campaign manager to former party member
Shirley de la Hunty who contested the
1989 Western Australian state election as an independent candidate. In 1993, following the collapse of his Australian Business College, he returned to serving the party in senior administrative positions, both state and federal, and successfully supported and mentored the Senate candidature of
Andrew Murray. ==Australian Business College==
