Lewis was first elected at the 1979 election as a Liberal candidate. He quickly gained a reputation as a maverick, defying the party authorities on many an occasion. In July 2000, the Liberals finally lost patience with Lewis and expelled him, even though it cost them their majority.[6]
At the 2002 election, Lewis contested his seat under the banner of the Community Leadership Independence Coalition (CLIC) and was re-elected. Three other CLIC candidates contested seats in the South Australian House of Assembly but failed.[7] During the campaign, Lewis said he would support any government that would commit to a program of parliamentary reform, including Labor. When pressed by The Advertiser, Lewis denied his statement meant he may help Labor form government, saying "You can quote me: That is bullshit. Clear, unequivocal, hot, green, sloppy, fresh bullshit. I'm not into forming government with Labor".[8]
Lewis' deal allowed Rann to form government by one seat. However, Kerin stated that since the Liberals had won the two-party vote on 50.9 percent, he would stay in office until Labor demonstrated it had support on the floor of the legislature. The House of Assembly reassembled earlier than normal after an election. With Lewis in the speaker's chair, Kerin moved a motion of confidence in his government. He lost, confirming Rann as premier. The Liberals hinted at challenging the result in Lewis' seat, but this did not eventuate.[10]
However, the other two independents, Rory McEwen and Bob Such, and the SA Nationals member, Karlene Maywald, later also agreed to support the Rann government in return for cabinet or speaker positions.[4][11]
Speaker
As speaker, he earned widespread attention for his colourful style of regulating parliamentary debate. The Rann government held a Constitutional Convention as promised in 2003, and as an outcome organised what ended up as failed attempts at bills for optional preferential voting, citizen initiated referendums and four-year Upper House terms.[12]
Terry Stephens
Lewis in 2002 faced media scrutiny over his links to businessman Terry Stephens (not to be confused with Liberal MP Terry Stephens) after claims were made in parliament, just prior to Lewis becoming speaker, by federal Liberal MP for Barker, Patrick Secker.[13][14][15] Lewis was exonerated of any wrongdoing despite submitting himself to extensive police investigations.[16] Stephens was later convicted of lying to smear Lewis.[17]
Standfield, Utting and Ratcliff
In 2004 Lewis and some of his staffers, including two child abuse activists and volunteer staffers named Malcolm Barry Standfield and Wendy Utting, were speaking to 8 informants about alleged pedophiles. One of the most vocal informants was named Craig Ratcliff and whilst he was providing plausible information that he had been a victim himself, he had also been found guilty as a perpetrator and is recorded as a convicted child sex offender.[18] Ratcliff was one of the informants who accused the MP during a television interview in August 2004. Ratcliff later recanted his claims, saying he realised the politician was not the man known as "Terry" who frequented gay beats in the late 1980s and early 1990s. He was subsequently convicted to a suspended prison sentence in 2008.[19]
Another of those informants named Robert Woodland was found bashed to death on 8 December 2004 in the South Parklands.[20] Then on 25 February 2005 another of the informants named Shaine Moore was found dead in suspicious circumstances.[21][22]
In early March 2005 the media and the Labor Government narrowed down the allegations of a pedophile politician to a male Labor Politician.[23] On 1 April 2005 Standfield and Utting faxed a press release, giving names of the alleged sitting MP and 2 policemen.
A police investigation of Standfield, Utting and Ratcliff started and all 3 were charged with criminal defamation.[24][25][26] In 2008 the two volunteer staffers working in Lewis' Office, Standfield and Utting, were found not guilty of defamation over the claims.[27][28][29] In December 2008 Ratcliff was sentenced for criminal defamation for the allegations.[30][31][32]
Resignation
On 4 April 2005 Lewis faced a potential motion of no confidence, but before a vote could be taken he gave a speech in parliament then resigned as speaker.[33][34][35]
2006 election
For the 2006 election, Lewis did not stand for his seat of Hammond, but instead stood as an independent for election to the Legislative Council. However he was not elected, receiving 0.6 percent of the statewide vote.[36][37]
2009 mining interests
Lewis owned eight mining leases, as well as interests in Goldus Operations and Mintech Resources. It was reported that Lewis had sold his iron ore project at Razorback Ridge, 80 km east of Yunta, to Western Australia's Royal Resources for $30 million.[38]
