preferred premier stakes. In 2008, O'Farrell led by-election campaigns in Lakemba, Ryde, and Cabramatta where the Coalition recorded the largest by-election swing against Labor in its history. The Liberals achieved a swing of 22.7% in Cabramatta and 13% in Lakemba. Ryde, once a safe Labor seat, was taken by Liberal Victor Dominello on a swing of 23.1%. On 2 September 2009, in the wake of the resignation of Labor's John Della Bosca following an affair, O'Farrell introduced a motion of no confidence on the Premier Nathan Rees and the NSW Government. O'Farrell was hoping to push an early election saying that "The job of changing New South Wales for the better needs to start today. The best thing that Nathan Rees could do is to allow the people to have their say through an early election". The motion was put to the house but defeated on party lines. Despite this, all independent members of the Legislative Assembly voted for the motion. In June 2010, the Liberals' Stuart Ayres won the Penrith by-election with a swing of 25%–at the time, the biggest swing against a sitting government in NSW history. The by-election was caused by the resignation of Karyn Paluzzano after she admitted rorting her electoral mail allowance and lying about it to the ICAC. A jubilant O'Farrell stated, "What we've seen this evening is the Liberal Party win its first seat in Western Sydney in 20 years. It demonstrates once and for all that Labor does not have a lock on Western Sydney." In August 2010, independent MP and lord mayor of Sydney Clover Moore introduced the Adoption Amendment (Same Sex Couples) Bill as a private member's bill, which, among other things, had the purpose of giving same-sex couples the right to adopt as a couple instead of as individuals. Both O'Farrell and Premier Kristina Keneally allowed a conscience vote on the bill. O'Farrell supported the reforms: "I support this measure today ... for the sake of children but also because I don't believe our society should exclude because of gender, sexuality, faith, background or some other factor, people who have a contribution they can make... That's not the free and confident society I seek." The bill was passed by the Legislative Assembly 46 votes to 44. In late 2010, following the government announcement of the sale of NSW's electricity assets, O'Farrell called for a judicial inquiry into the matter.
