were reduced to 1.7 per cent of the Legislative Council (upper house) vote. Their sole councillor up for re-election, Kate Reynolds, was defeated. In July 2006, Richard Pascoe, national and South Australian party president, resigned, citing slumping opinion polls and the poor result in the 2006 South Australian election as well as South Australian parliamentary leader Sandra Kanck's comments regarding the drug MDMA which he saw as damaging to the party. In the New South Wales state election of March 2007, the Australian Democrats lost their last remaining NSW Upper House representative, Arthur Chesterfield-Evans. The party fared poorly, gaining only 1.8 per cent of the Legislative Council vote. On 13 September 2007, the ACT Democrats (Australian Capital Territory Division of the party) was deregistered by the ACT Electoral Commissioner, being unable to demonstrate a minimum membership of 100 electors. These losses left Sandra Kanck, in South Australia, as the party's only parliamentarian. She retired in 2009 and was replaced by David Winderlich, making him (as of 2020) the last Democrat to sit in any Australian parliament. The Democrats lost all representation when Winderlich resigned from the party in October 2009. He sat the remainder of his term as an independent, and lost his seat at the 2010 South Australian election. Post-parliamentary decline Following the loss of all Democrats MP's in both federal and state parliaments, the party continued to be riven by factionalism. In 2009 a dispute arose between two factions, the "Christian Centrists" loyal to former leader Meg Lees, and a faction comprising the party's more progressive members. The dispute arose when the Christian Centrist controlled national executive removed a website for party members from the internet, stating that its operation was a violation of the party constitution. In response, the progressive faction accused the national executive of being undemocratic and of acting contrary to the party constitution themselves. By 2012, this dispute had been superseded by another between members loyal to former Senator Brian Greig and members who were supporters of former South Australian MP Sandra Kanck. Brian Greig was elected the party's president, but resigned after less than a month due to frustration with the party's factionalism. Deregistration On 16 April 2015, the Australian Electoral Commission deregistered the Australian Democrats as a political party for failure to demonstrate the requisite 500 members to maintain registration. However, the party did run candidates and remain registered for a period
