The 2009 Washington Referendum 71 (R-71) legalized domestic partnership in Washington state, the first statewide referendum in the United States that extended to LGBT people the rights and responsibility of domestic partnership. The bill had passed State Legislature, and it was signed into law by the Governor in May 2009, but opponents gathered enough signatures to put the measure before the voters, who returned ballots by mail over three weeks ending on November 3, 2009, approving the measure 53% to 47%. The new law went into effect 30 days later, on December 3, 2009.
