 Costa refused to step down and went on to win election in the 2007 state election.During 2009, Costa came under heavy criticism from Wollondilly Councillor Benn Banasik, Mayor of Camden Council Chris Patterson and Councillor Jai Rowell (who would become his Liberal opponent in Wollondilly in 2011) for the Labor Government's approval of the AGL Power Station at Appin.Wollondilly Council passed a resolution from Councillor Benn Banasik requesting Costa to resign but this was later withdrawn.
