Same-sex marriage has been legal in New Hampshire since January 1, 2010, based on legislation signed into law by Governor John Lynch on June 3, 2009. The law provided that civil unions, which the state had established as of January 1, 2008, would be converted to marriages on January 1, 2011, unless dissolved, annulled, or converted to marriage before that date.
Following the first same-sex marriages in Massachusetts in May 2004, New Hampshire established a 14-member commission to consider the question of civil recognition of same-sex relationships. The group, composed of legislators, politicians, and activists, reported its findings in November 2005. By a 7-to-4 vote it recommended modifying the State Constitution to restrict marriage to heterosexual unions, reinforcing the state's statutory definition of marriage to prevent the judiciary from finding a constitutional requirement that same-sex couples be allowed to wed. Their report opposed as well the idea of civil unions like those recognized in Vermont in July 2000. The commission proposed instead certificates that would guarantee certain rights like hospital visitation, but no financial benefits. The certificates would be available to siblings, parents, and children as well. The commission members who dissented said it spent too much time hearings attacks on the morality of homosexuality. The chairman, Tony Soltani, a Republican member of the state House of Representatives, said; "If we redefined marriage, we'd be tarred and feathered, but if we give them some rights, it will be accepted." He said homosexuality could not be compared to race, because it is an "acquired behavior" or a "combination of both nature and nurture." He added: "I know it's not a long-term solution, but it is something a child can point to and say, my representatives say I'm OK, and I'm not a freak."
Democrats became the majority party in the New Hampshire State Legislature in the 2006 general election. Both Democratic and Republican legislators proposed legislation to grant same-sex couples greater civil rights. The proposals ranged from allowing a couple to enter into a "contractual cohabitation," a "civil union," a "spousal union," or a same-sex marriage. Governor John Lynch opposed same-sex marriage, but indicated that he was receptive to discussing civil unions as a means of granting certain rights to same-sex couples.
