Tzipi Livni parties to agree to join a new coalition under Prime Minister Benjamin Netanyahu, forming the thirty-third government of Israel. According to the coalition agreement negotiated between Hatnuah and Likud, Livni was appointed justice minister, as well as chief negotiator with the Palestinian Authority. As environmental issues constituted a central plank in Hatnuah's platform, Livni required her party be given the environmental protection ministry, to which she appointed Amir Peretz. Fulfilling her constitutional duty as Justice Minister, Livni served as chairwoman of the powerful Ministerial Committee on Legislation. Given her clout and experience with Western leaders, Netanyahu unofficially charged Livni with
Meretz new chairman. On 22 December 2008, Meretz finalized its merger with Hatnua HaHadasha ("The New Movement") for the 2009 Israeli elections. The joint Meretz-Hatnua HaHadasha list ended up winning only 3 seats in the elections. This electoral loss was largely attributed to traditionally left-wing voters choosing to strategically vote for Kadima, in an effort to get Tzipi Livni to head the next government instead of Benjamin Netanyahu of Likud. Following the party's failure in the 2009 legislative elections, some of the party members called for the resignation of the party chairman Haim Oron and to give way for Zehava Gal-On.
