12 June 2008, a day after a vote on the extension of detention of terror suspects without charge, in an unexpected move, Davis took the Chiltern Hundreds, effectively resigning his seat as the constituency's MP. He stated this was to force a by-election, in which he intended to provoke a wider public debate on the single issue of the perceived erosion of civil liberties. Over the course of the following week, the campaign was launched on the theme of David Davis for Freedom. Davis formally resigned as an MP on 18 June 2008, and the by-election took place on 10 July 2008, which Davis won.
