Proposition 2 was a referendum for a state constitutional amendment placed on the ballot by the Texas legislature and approved by the voters at the November 8, 2005 general election. The measure added a new provision to the Texas Constitution, Article 1, Section 32, which provides that "Marriage in this state shall consist only of the union of one man and one woman", and "This state or a political subdivision of this state may not create or recognize any legal status identical or similar to marriage." Texas thus became the nineteenth US state to adopt constitutional amendment banning same-sex marriage. It was the most populous state to adopt a constitutional ban on same-sex marriage until California passed its ban in November 2008. Full text Article 1, Section 32 of the Texas Constitution, as amended, states: The joint resolution proposing the amendment included additional language about rights that the ban on same-sex marriage was not meant to restrict: Legislative approval As provided in Article 17, Section 1 of the Texas Constitution, a proposed constitutional amendment is placed on the ballot only after the Texas legislature has proposed the amendment in a joint resolution of both the Texas senate and the Texas house of representatives. The joint resolution may originate in either chamber. The resolution must be adopted by a vote of at least two-thirds of the membership of each chamber. That means a minimum of 100 votes in the house and 21 votes in the senate. On April 25, 2005, the house voted 101 in favor and 29 against the proposed amendment to ban same-sex marriage and civil unions, authored by Warren Chisum. On May 21, 2005, the senate voted 21 in favor and 8 against the proposed amendment, and the ballot was set for November 8.
