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. Prior to this Washington state vote, a ban on same-sex marriages and civil unions, Arizona Proposition 107, was rejected by voters in that state in 2006, who two years later passed the civil-unions-neutral Arizona Proposition 102. History Senate Bill 5688 was signed by Governor Christine Gregoire on May 18, 2009. On July 25, 2009, the organization Protect Marriage Washington submitted petitions containing 137,881 signatures to the Washington Secretary of State's office. State law requires at least 120,577 valid signatures to qualify for the October–November 2009 ballot. The Secretary of State officially verified 122,007 of the signatures on September 1, 2009. Under the State Constitution, laws passed by the legislature do not take effect until ninety days after the close of the legislative session, unless the Legislature declares an emergency, which would put the law in effect immediately. During this ninety-day period citizens can attempt to force a referendum by gathering enough verified signatures, at least four percent of the number of voters in the previous gubernatorial election. A successful petition places the law on hold, pending a referendum in the next election. Enactment of the Washington Legislature-approved law was initially halted pending signature-verification; having received sufficient valid signatures to require voter re-confirmation, the state extended the hold until the results of the 2009 general election were made official. Several lawsuits were filed to block R-71 from appearing on the ballot, but none was successful in court. A second challenge to the ballot certification brought in Thurston County by Arthur West was dismissed upon the Secretary of State's misrepresentation of the scope of the federal injunction. A third challenge brought by WFST was dismissed by agreement without review of the signature sheets. There was an active lawsuit to be heard by the Supreme Court to decide if and when signatories to ballot measures are to be revealed
