Hawaii legislators have shelved a proposal to create civil unions for same-sex couples, indicating that the state legislature did not have enough votes to pass the law.

The state House Judiciary Committee declined to vote on the proposal after hours of testimony Tuesday without explaining the reasons for deferring debate. Hawaii was one of the first states to consider same-sex marriage when the Hawaii Supreme Court ruled in 1996 that same-sex couples cannot be denied marriage, but a 1998 constitutional amendment defined marriage as a union between a man and a woman.

Vermont, Connecticut and New Jersey each recognize civil unions for same-sex couples, while Massachusetts is the only US state to legally recognize same-sex marriage. Earlier this month, New Jersey became the first state to recognize same-sex marriage and civil unions from out of state jurisdictions.
