On 3 December 2011, delegates to the ALP national conference voted in favour of the amendment to the party platform moved by Prime Minister, Julia Gillard, allowing members a conscience vote on same-sex marriage (208 votes to 184). Members of the Left faction had argued strongly against treating same-sex marriage as a conscience issue. Delegates also agreed to change the definition of marriage (carried unanimously on the voices) by:
... amend[ing] the Marriage Act to ensure equal access to marriage under statute for all adult couples, irrespective of sex, who have a mutual commitment to a shared life. These amendments should ensure that nothing in the Marriage Act imposes an obligation on a minister of religion to solemnise any marriage.
